EXPLANATORY NOTE

First Mining Gold Corp. (the “Company” or the “Registrant”) is a Canadian issuer eligible, pursuant to Section 13 of the Securities Exchange Act, to file its annual report on
Form 40-F pursuant to the multi-jurisdictional disclosure system of the Exchange Act. The Company is a “foreign private issuer” as defined in Rule 3b-4 under the Exchange
Act. Equity securities of the Company are accordingly exempt from Sections 14(a), 14(b), 14(c), 14(f) and 16 of the Exchange Act pursuant to Rule 3a12-3.

FORWARD-LOOKING STATEMENTS

This annual report on Form 40-F and the exhibits attached hereto contain “forward-looking statements” within the meaning of the United States Private Securities Litigation
Reform  Act  of  1995  and  “forward-looking  information”  within  the  meaning  of  applicable  Canadian  securities  legislation.  Forward-looking  statements,  which  are  all
statements other than statements of historical fact, include, but are not limited to, statements with respect to the future price of commodities, the estimation of mineral reserves
and  mineral  resources,  the  realization  of  mineral  reserve  estimates,  the  timing  and  amount  of  estimated  future  production,  costs  of  production,  reserve  determination  and
reserve conversion rates. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “plans”, “expects” or “does not
expect”,  “is  expected”,  “budget”,  “scheduled”,  “estimates”,  “forecasts”,  “intends”,  “anticipates”  or  “does  not  anticipate”,  or  “believes”,  or  variations  of  such  words  and
phrases or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved”. Forward-looking statements are
subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of the Company to be
materially different from those expressed or implied by such forward-looking statements, including but not limited to: fluctuations in the price of commodities; expectations
and  anticipated  impact  of  the  COVID-19  pandemic;  risks  related  to  mining  and  exploration  operations  including  risks  related  to  fluctuations  in  the  price  of  the  primary
commodities  mined  at  such  operations,  actual  results  of  mining  and  exploration  activities,  economic  and  political  risks  of  the  jurisdictions  in  which  the  mining  and
exploration  operations  are  located,  changes  in  project  parameters  as  plans  continue  to  be  refined;  and  differences  in  the  interpretation  or  application  of  tax  laws  and
regulations;  as  well  as  those  factors  discussed  in  the  section  entitled  “Risks  that  can  affect  our  business”  in  the  Company’s  annual  information  form  (the  “AIF”)  for  the
financial  year  ended  December  31,  2020.  Forward-looking  statements  are  based  on  assumptions  management  believes  to  be  reasonable,  including  but  not  limited  to:  no
material adverse change in the market price of commodities, that the mining and exploration operations will operate and the mining projects will be completed in accordance
with their public statements and achieve their stated production outcomes, and such other assumptions and factors as set out herein. Although the Company has attempted to
identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results
not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate. Accordingly, readers should not place
undue reliance on forward-looking statements. The forward-looking statements and forward-looking information contained or incorporated by reference in this annual report
on  Form  40-F  are  included  for  the  purpose  of  providing  investors  with  information  to  assist  them  in  understanding  the  Company’s  expected  financial  and  operational
performance and may not be appropriate for other purposes. The Company does not undertake to update any forward-looking statements that are included or incorporated by
reference herein, except in accordance with applicable securities laws.

NOTE TO UNITED STATES READERS – DIFFERENCES
IN UNITED STATES AND CANADIAN REPORTING PRACTICES

The  Company  is  permitted,  under  a  multi-jurisdictional  disclosure  system  adopted  by  the  United  States,  to  prepare  this  annual  report  on  Form 40-F  in  accordance  with
Canadian disclosure requirements, which are different from those of the United States. The Company prepares its financial statements (the “Audited Financial Statements”)
in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”).

The AIF filed as Exhibit 99.1 to this annual report on Form 40-F has been prepared in accordance with the requirements of the securities laws in effect in Canada, which
differ from the requirements of United States securities laws. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining
terms as defined in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining,
Metallurgy and Petroleum (“CIM”)  Definition  Standards  on  Mineral  Resources  and  Mineral  Reserves,  adopted  by  the  CIM  Council,  as  amended.  These  definitions  differ
from the definitions in the United States Securities and Exchange Commission (the “SEC”) rules applicable to domestic United States companies.

Accordingly, information contained in this annual report on Form 40-F and the documents incorporated by reference herein containing descriptions of the Company’s mineral
deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal
securities laws and the rules and regulations thereunder.

subsidiaries is the Canadian dollar while the functional currency of the Company’s non-Canadian subsidiaries is the US dollar. The financial statement presentation currency

MANAGEMENT’S DISCUSSION AND ANALYSIS

See Exhibits 99.4, 99.5, 99.6 and 99.7, which are included as Exhibits to this annual report on Form 40-F.

DISCLOSURE CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

CERTIFICATIONS

As of the end of the period covered by this annual report on Form 40-F, an evaluation was carried out under the supervision of, and with the participation of, the Company’s
management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the Company’s disclosure controls and procedures
(as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the Exchange Act). Based upon the results of that evaluation, the CEO and the CFO have concluded that as of the
end of the period covered by this annual report on Form 40-F, the Company’s disclosure controls and procedures were effective. Disclosure controls and procedures include
controls and other procedures that are designed to ensure that (i) information required to be disclosed by the Company in reports that it files or submits to the SEC under the
Exchange Act is recorded, processed, summarized and reported within the appropriate time periods specified in applicable rules and forms and (ii) information required to be
disclosed  by  the  Company  in  reports  filed  under  the  Exchange  Act  is  accumulated  and  communicated  to  the  Company’s  management,  including  the  CEO  and  CFO,  as
appropriate, to allow for accurate and timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

The Company’s management, with the participation of the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting as
defined  in  Rules  13a-15(f)  and  15d-15(f)  under  the  Exchange  Act.  The  Company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  and  fair  presentation  of  financial  statements  for  external  purposes  in  accordance  with
International  Financial  Reporting  Standards  as  issued  by  the  International  Accounting  Standards  Board.  The  Company’s  internal  control  over  financial  reporting  includes
policies and procedures that:

● maintain records that accurately and fairly reflect, in reasonable detail, the transactions and dispositions of assets of the Company;
● provide reasonable assurance that transactions are recorded as necessary for preparation of financial statements in accordance with IFRS;
● provide  reasonable  assurance  that  the  Company’s  receipts  and  expenditures  are  made  only  in  accordance  with  authorizations  of  management  and  the  Company’s

Directors; and

● provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition  of  the  Company’s  assets  that  could  have  a

material effect on the Company’s consolidated financial statements.

Because  of  its  inherent  limitations,  the  Company’s  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Additionally,  projections  of  any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020, based on the criteria set forth in Internal Control
– Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation
of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Based on this evaluation,
management has concluded that the Company’s internal control over financial reporting was effective and no material weakness was identified as at December 31, 2020.

Attestation Report of the Registered Public Accounting Firm

This Annual Report on Form 40-F does not include an attestation report of the Company’s registered public accounting firm because the Company qualified as an "emerging
growth company" pursuant to Section 2(a)(19) of the Securities Act of 1933 during the year covered by this Annual Report on Form 40-F, and this Annual Report on Form
40-F is therefore not required to include such an attestation report.

Changes in Internal Control over Financial Reporting

During the period covered by this annual report on Form 40-F, no change occurred in the Company’s internal control over financial reporting that has materially affected, or is
reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations of Controls and Procedures

The Company’s management, including the CEO and CFO, does not expect that its disclosure controls and procedures or internal controls and procedures will prevent all
error  and  all  fraud.  A  control  system,  no  matter  how  well  conceived  and  operated,  can  provide  only  reasonable,  not  absolute,  assurance  that  the  objectives  of  the  control
system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their
costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any,
within  the  Company  have  been  detected.  These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty,  and  that  breakdowns  can  occur
because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management
override  of  the  control.  The  design  of  any  system  of  controls  also  is  based  in  part  upon  certain  assumptions  about  the  likelihood  of  future  events,  and  there  can  be  no
assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in
conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements
due to error or fraud may occur and not be detected.

Audit Committee

AUDIT COMMITTEE

accounting  principles  in  connection  with  the  accounting  for  estimates,  accruals  and  reserves.  Mr.  Polman  also  has  experience  preparing,  auditing,  analyzing  or  evaluating
financial  statements  that  present  a  breadth  and  level  of  complexity  of  accounting  issues  that  are  generally  comparable  to  the  breadth  and  complexity  of  issues  that  can
reasonably be expected to be raised by the Company’s financial statements (or actively supervising another person who did so). Mr. Polman also has an understanding of
internal  controls  and  procedures  for  financial  reporting  and  an  understanding  of  audit  committee  functions.  Mr.  Polman  has  experience  as  a  principal  financial  officer,

National Instrument 43-101 definitions

Canadian  reporting  requirements  for  disclosure  of  mineral  properties  are  governed  by  National  Instrument  43-101  Standards  of  Disclosure  for  Mineral  Projects (“NI 43-
101”). The definitions in NI 43-101 are adopted from those given by the Canadian Institute of Mining Metallurgy and Petroleum (“CIM”).

Qualified Person

Mineral Resource

The  term  “Qualified  Person”  refers  to  an  individual  who  is  an  engineer  or  geoscientist  with  at  least  five  years  of  experience  in
mineral  exploration,  mine  development,  production  activities  and  project  assessment,  or  any  combination  thereof,  including
experience  relevant  to  the  subject  matter  of  the  project  or  report  and  is  a  member  in  good  standing  of  a  self-regulating
organization.

The  term  “Mineral  Resource”  refers  to  a  concentration  or  occurrence  of  diamonds,  natural  solid  inorganic  material,  or  natural
solid fossilized organic material including base and precious metals, coal and industrial minerals in or on the Earth’s crust in such
form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity,
grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from
specific geological evidence and knowledge, including sampling.

Inferred Mineral Resource

The term “inferred mineral resource” refers to that part of a mineral resource for which quantity and grade or quality are estimated
on  the  basis  of  limited  geological  evidence  and  limited  sampling.  Geological  evidence  is  sufficient  to  imply  but  not  verify
geological  and  grade  or  quality  continuity.  The  estimate  is  based  on  limited  information  and  sampling  gathered  through
appropriate sampling techniques from locations such as outcrops, trenches, pits, workings and drill holes.

Indicated Mineral Resource

Measured Mineral Resource

The term “Indicated Mineral Resource” refers to that part of a Mineral Resource for which quantity, grade or quality, densities,
shape and physical characteristics can be estimated with sufficient confidence to allow the appropriate application of modifying
factors (including, but not limited to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environment,
social  and  governmental  factors)  in  sufficient  detail  to  support  mine  planning  and  evaluation  of  the  economic  viability  of  the
deposit.  The  estimate  is  based  on  detailed  and  reliable  exploration  and  testing  information  gathered  through  appropriate
techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to reasonably
assume geological and grade or quality continuity between points of observation. An Indicated Mineral Resource has a lower level
of confidence than that applying to a “Measured Mineral Resource” and may only be converted to a “Probable Mineral Reserve”.

The term “Measured Mineral Resource” refers to that part of a Mineral Resource for which quantity, grade or quality, densities,
shape and physical characteristics can be estimated with sufficient confidence to allow the appropriate application of modifying
factors (including, but not limited to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environment,
social  and  governmental  factors)  in  sufficient  detail  to  support  detailed  mine  planning  and  final  evaluation  of  the  economic
viability  of  the  deposit.  The  estimate  is  based  on  detailed  and  reliable  exploration,  sampling  and  testing  information  gathered
through  appropriate  techniques  from  locations  such  as  outcrops,  trenches,  pits,  workings  and  drillholes  that  are  spaced  closely
enough to confirm geological and grade or quality continuity between points of observation. A Measured Mineral Resource has a
higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be
converted to a “Proven Mineral Reserve” or to a Probable Mineral Reserve.

Mineral Reserve

Probable Mineral Reserve

Proven Mineral Reserve

The term “Mineral Reserve” refers to that part of a Measured and/or Indicated Mineral Resource which, after the application of all
mining factors, result in an estimated tonnage and grade which, in the opinion of the Qualified Person(s) making the estimates, is
the  basis  of  an  economically  viable  project  after  taking  account  of  all  relevant  modifying  factors  (including,  but  not  limited  to,
mining,  processing,  metallurgical,  infrastructure,  economic,  marketing,  legal,  environment,  social  and  governmental  factors).  It
includes  diluting  materials  that  will  be  mined  in  conjunction  with  the  Mineral  Reserves  and  delivered  to  the  treatment  plant  or
equivalent  facility,  as  well  as  allowances  for  losses  which  may  occur  when  the  material  is  mined  or  extracted,  and  Mineral
Reserves are defined by studies at pre-feasibility or feasibility level, as appropriate. Such studies demonstrate that, at the time of
reporting, extraction could reasonably be justified. The term Mineral Reserve does not necessarily signify that extraction facilities
are in place or operative or that all governmental approvals have been received. It does, however, signify that there are reasonable
expectations of such approvals.

The  term  “Probable  Mineral  Reserve”  refers  to  the  economically  mineable  part  of  an  Indicated  Mineral  Resource,  and  in  some
circumstances,  a  Measured  Mineral  Resource.  The  confidence  in  the  modifying  factors  (including,  but  not  limited  to,  mining,
processing, metallurgical, infrastructure, economic, marketing, legal, environment, social and governmental factors) applying to a
Probable Mineral Reserve is lower than that applying to a “Proven Mineral Reserve”. Probable Mineral Reserve estimates must be
demonstrated to be economic, at the time of reporting, by at least a pre-feasibility study.

The term “Proven Mineral Reserve” refers to the economically mineable part of a Measured Mineral Resource. A Proven Mineral
Reserve  implies  that  the  Qualified  Person  has  the  highest  degree  of  confidence  in  the  estimate  and  the  modifying  factors
(including,  but  not  limited  to,  mining,  processing,  metallurgical,  infrastructure,  economic,  marketing,  legal,  environment,  social
and governmental factors). Use of the term is restricted to that part of the deposit where production planning is taking place and
for  which  any  variation  in  the  estimate  would  not  significantly  affect  the  potential  economic  viability  of  the  deposit.  Proven
Mineral Reserve estimates must be demonstrated to be economic, at the time of reporting, by at least a pre-feasibility study.

About First Mining

First Mining Gold Corp. is a Canadian-focused gold exploration and development company that was created in 2015 by Mr. Keith Neumeyer, founding President and CEO of
First Majestic Silver Corp. and a co-founder of First Quantum Minerals Ltd.

We are a Canadian gold developer, with our primary focus being the development and permitting of our Springpole Gold Project (the “Springpole Project” or “Springpole”)
in northwestern Ontario. Springpole is one of the largest undeveloped gold projects in Canada. We announced the results of a positive Pre-Feasibility Study for the Springpole
Gold Project in January 2021, and permitting activities are on-going with submission of an Environmental Impact Statement for the project targeted by the end of 2021. We
also hold a large equity position in Treasury Metals Inc. (“Treasury Metals”) which is advancing the Goliath Gold Complex project towards construction. Our portfolio of
gold projects in eastern Canada also includes the Pickle Crow (being advanced in partnership with Auteco Minerals Ltd.), Cameron, Hope Brook, Duparquet, Duquesne, and
Pitt gold projects.

We are publicly listed on the Toronto Stock Exchange (“TSX”) under the trading
symbol “FF”, in the US on the OTC-QX under the trading symbol “FFMGF”, and on
the Frankfurt Stock Exchange under the symbol “FMG”. Our management team has
decades of experience in evaluating, exploring and developing mineral assets.

Vision and strategy

We hold a portfolio of 13 mineral assets in Canada and the United States, with a focus on gold. Our vision is to advance our material assets toward a construction decision
and, ultimately, to production.

To achieve this goal, our strategy is to:

● advance the Springpole Project to a construction decision by taking Springpole through the environmental assessment process and completing a feasibility study for

the project;

● de-risk our material assets through exploration, drilling, calculating resource estimates, conducting engineering, environmental and economic studies, advancing the

projects through permitting processes and other activities;

● surface value for our portfolio of assets by finding partners to help advance them by committing financial and human capital to advance and de-risk them;

● utilize our management team’s expertise to successfully permit, finance and construct producing mines at our material assets, either on our own or with financial or

operating partners; and

● continue to grow our asset base by acquiring additional mineral assets.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We may acquire additional mineral assets in the future. We consider the following criteria when assessing potential acquisition targets:

● Quality of asset – we consider factors such as economics, grade, size and exploration potential, metallurgy and mineability (eg. strip ratio) when assessing a new

mineral property.

● Location – we are focused on assets located in politically stable and mining friendly jurisdictions.

● Compatibility with our existing asset base – we consider whether a project can improve the economic or strategic value of our existing projects.

● Availability of infrastructure – we consider whether the project has good access to power, water, highways, ports and a labour force.

● Holding costs – we take into account the holding costs (eg. assessment work requirements) and annual taxes payable on the mineral claims when deciding whether to

acquire a new mineral property.

● Valuation – we look for attractively valued resources to add to our portfolio.

General overview of our business

We are in the exploration and development stage, and we do not currently own any producing properties. Consequently, we have no current operating income or cash flow
from our properties, nor have we had any income from operations in the past three financial years. At this time, our operations are primarily funded by equity financings.

An investment in First Mining is speculative and involves a high degree of risk due to the nature of our business and the present stage of exploration of our mineral properties.
We encourage readers to carefully consider the risk factors that are set out in this AIF in the section “Risks that can affect our business” which starts on page 92.

Principal products

We are currently in the exploration and development stage and do not produce or sell mineral products. Our principal focus is on gold.

Specialized skills and knowledge

Our  business  requires  individuals  with  specialized  skills  and  knowledge  in  the  areas  of  geology,  drilling,  geophysics,  geochemistry,  metallurgy,  engineering  and  mineral
processing,  implementation  of  exploration  programs,  mine  engineering,  environmental  assessment  and  mine  permitting,  acquisitions,  capital  raising,  mine  finance,
accounting, and environmental compliance. In order to attract and retain personnel with such skills and knowledge, we maintain competitive remuneration and compensation
packages. To date, we have been able to locate and retain such professionals in Canada and in the US, and we believe we will be able to continue to do so.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Competitive conditions

The  precious  metal  mineral  exploration  and  mining  industry  is  very  competitive  in  all  phases  of  exploration  and  development,  and  we  compete  with  numerous  other
companies and individuals in the search for, and the acquisition and development of, attractive precious metal mineral properties.

As a result of this competition, we may at times compete with other companies that have greater financial resources and technical facilities, and we may compete with other
exploration and mining companies for the procurement of equipment and for the availability of skilled labour, which means that there may be times where we are unable to
attract or retain qualified personnel. As well, we cannot assure you that additional capital or other types of financing will be available if needed or that, if available, the terms
of such financing will be favourable to us.

As a result of the competitors in our industry, many of whom have greater financial resources than us, the Company may be unable to acquire attractive mineral properties in
the future on terms it considers acceptable. We also compete with other companies when it comes to: (a) raising the capital necessary to fund our operations and the potential
development of our properties; and (b) obtaining the resources to conduct exploration and development activities on our properties.

Cycles

The mining business is subject to commodity price cycles. The gold market, late in 2010, made significant gains in terms of US dollars but remained volatile throughout 2011
and suffered significant declines in 2013 and 2014. The financial markets for mining in general and mineral exploration and development in particular, continued to be weak
through to the end of 2020 and, as a result of the COVID-19 crisis and the response of governments and the private sector to COVID-19, markets are experiencing extreme
volatility as of the date of this AIF. The long-term effects of this pandemic on financial markets and the economy in general is at present unknown. If the global economy
stalls and commodity prices decline as a consequence, a continuing period of lower prices could significantly affect the economic potential of many of our current properties
and may result in First Mining ceasing work on, or dropping its interest in, some or all of our properties. As we do not currently undertake production activities, our ability to
fund ongoing exploration is affected by the availability of financing (and particularly equity financing) which, in turn, is affected by the strength of the economy, commodity
prices and other general economic factors.

In addition, our mineral exploration activities may be subject to seasonality due to adverse weather conditions at our project sites. Drilling and other exploration activities on
our properties may be restricted during the winter season as a result of various weather-related factors including, without limitation, inclement weather, snow covering the
ground, frozen ground and restricted access due to snow, ice or other weather-related factors. In addition, access to the Springpole site for bulk material haulage is by a winter
ice road. The quality, functionality and duration of this access depends on temperatures being cold enough for a sufficient period of time. Failure to build or maintain winter
access can result in delays in our work programs and higher operating costs.

Economic dependence

Our  business  is  dependent  on  the  acquisition,  exploration,  development  and  operation  of  mineral  properties.  We  are  not  dependent  on  any  contract  to  sell  our  products  or
services or to purchase the major part of our requirements for goods, services or raw materials, or on any franchise or licence or other agreement to use a patent, formula,
trade secret, process or trade name upon which our business depends.

15

 
 
 
 
 
 
 
 
 
 
 
 
Employees

As  of  the  date  of  this  AIF,  we  have  21  full-time  employees,  and  we  utilize  consultants  and  contractors  as  needed  to  carry  on  many  of  our  activities  and,  in  particular,  to
supervise and carry out the work programs at our mineral projects.

Environmental protection

We are subject to the laws and regulations relating to environmental matters in all jurisdictions in which we operate, including provisions relating to property reclamation,
discharge of hazardous materials and other matters.

We  may  also  be  held  liable  should  environmental  problems  be  discovered  that  were  caused  by  former  owners  and  operators  of  our  projects.  We  conduct  our  mineral
exploration activities in compliance with applicable environmental protection legislation. A reclamation liability amount of $3.4 million was recorded in our audited annual
financial statements as at December 31, 2020 with respect to our Pickle Crow gold project in Ontario. We are not aware of any existing environmental issues relating to any of
our other properties that may result in material liability to First Mining.

New  environmental  laws  and  regulations,  amendments  to  existing  laws  and  regulations,  or  more  stringent  implementation  of  existing  laws  and  regulations  could  have  a
material adverse effect on us, both financially and operationally, by potentially increasing capital and/or operating costs and delaying or preventing the development of our
mineral properties.

We  believe  that  the  policies  and  procedures  implemented  by  our  executive  management  team  provide  a  safe  working  environment  for  all  our  employees,  consultants,
contractors,  stakeholders  and  rights  holders.  We  recognize  that  safety  and  environmental  due  diligence  are  significant  contributors  to  the  long-term  sustainability  of  our
operations and support our objective of projects being completed in a cost effective and timely manner with excellent quality control.

Bankruptcy and similar procedures

There are no bankruptcies, receivership or similar proceedings against us, nor are we aware of any such pending or threatened proceedings. We have not commenced any
bankruptcy, receivership or similar proceedings during our history.

Our projects

We have interests in mineral properties located in Canada and the United States. As at December 31, 2020, these properties were carried on our balance sheet as assets with a
total book value of approximately $179 million. The book value consists of acquisition costs plus cumulative expenditures on properties for which the Company has future
exploration plans. The current book value is not necessarily the same as the total cumulative expenditures on each property given the acquisition costs were based on the
consideration paid at the time of purchase. The book value is also not necessarily the fair market value of the properties.

Our material and non-material projects as of the date of this AIF are set out below.

Project description, location and access

The Springpole Project lies approximately 110 km northeast of the Municipality of Red Lake in northwest Ontario, Canada. The project is centered on a temporary tent-based
camp situated on a small land bridge between Springpole Lake and Birch Lake. The latitude and longitude coordinates are:

● Latitude                         N51° 23ʹ 44.3ʺ

● Longitude                      W92° 17ʹ 37.4ʺ

The Universal Transverse Mercator map projection based on the World Geodetic System 1984 zone 15N is:

● Easting                           549,183

● Northing                        5,693,578

● Average Elevation         395 m

During late spring, summer, and early fall, the Springpole Project is accessible by floatplane direct to Springpole Lake or Birch Lake. All fuel, food, and material supplies are
flown in from Red Lake or Pickle Lake, Ontario, or from Winnipeg, Manitoba, with flight distances of 110 km, 167 km, and 370 km, respectively. The closest road access at
present is 15 km away at the extension of the Wenesaga forestry road.

During winter, an ice road approximately 85 km long is constructed from the South Bay landing point on Confederation Lake to a point about 1 km from the Springpole Lake
camp.  During  breakup  in  spring  and  freeze-up  in  fall,  access  to  the  Springpole  Project  is  by  helicopter.  Additional  winter  access  may  be  available  via  temporary  airstrips
cleared on nearby frozen lakes.

First Mining acquired 100% of the Springpole Project on November 13, 2015 when it completed the acquisition of Gold Canyon Resources Inc. (“Gold Canyon”). When the
Springpole Project was acquired from Gold Canyon, it consisted of 30 patented mining claims and 300 unpatented, contiguous mining claims and six Crown mining leases,
totalling an area of approximately 32,448 ha. Additional mining claims were subsequently acquired by First Mining in the Satterly Lake area, and the original unpatented
‘legacy’ claims were converted into the new Ontario cell claim system in April 2018. A further seven mining leases were acquired by Gold Canyon in 2019 by conversion of
existing  mining  claims  covering  1,531  ha  to  mining  leases.  The  Springpole  Project  currently  comprises  30  patented  mining  claims,  282  contiguous  mining  claims  and  13
mining leases. The area covered by the Project has increased since 2015 to its current total of 41,943 ha.

Through Gold Canyon, we lease 10 patented mining claims covering a total area of 182.25 ha. These 10 patented claims are fee simple parcels with all mining and surface
rights  attached,  and  registered,  together  with  the  notices  of  lease,  with  the  Land  Registry  Office  in  Kenora,  Ontario.  The  lease  is  for  a  term  of  21  years  less  one  day  and
terminates on April 14, 2031. Pursuant to an amending agreement dated December 11, 2020 among First Mining, Gold Canyon and the leaseholder:

● We  have  an  option  to  purchase  these  10  patented  mining  claims  from  December  11,  2020  until  April  15,  2021  (“Purchase  Option  1”)  for  US$7,000,000,  of  which

US$1,000,000 may be satisfied by the issuance of common shares of First Mining (“First Mining Shares”) to the leaseholder.

● We  have  the  option  to  purchase  these  10  patented  mining  claims  from  April  16,  2021  until  April  15,  2025  (“Purchase  Option  2”)  for  US$8,000,000,  of  which

US$2,000,000 may be satisfied by the issuance of First Mining Shares to the leaseholder.

29

 
 
 
 
 
 
 
 
 
 
 
 
 
● If, on or before April 15, 2025, First Mining provides the leaseholder with written notice, pays US$250,000 to the leaseholder and issues 1,000,000 First Mining Shares
to  the  leaseholder,  we  acquire  a  further  option  to  purchase  these  10  patented  mining  claims  from  April  16,  2025  until  April  14,  2031  (“Purchase  Option  3”)  for
US$10,000,000, less US$250,000. Of the total purchase price, US$3,000,000 may be satisfied by the issuance of First Mining Shares to the leaseholder.

● If, on or before April 14, 2031, First Mining provides the leaseholder with written notice and pays US$2,000,000 in cash to the leaseholder, the 21-year term of the lease
shall automatically be extended by five additional years and the new expiry date of the lease will be April 14, 2036. In addition, we would immediately acquire a further
option to purchase the 10 patented mining claims from April 15, 2031 until April 14, 2036 (“Purchase Option 4”) for US$12,000,000, less US$2,250,000. Of the total

● If, on or before April 14, 2036, First Mining provides the leaseholder with written notice and pays a further US$2,000,000 in cash to the leaseholder, then the term of the
lease shall automatically be further extended by five additional years and the new expiry date of the lease will be April 14, 2041. In addition, we would immediately
acquire a final irrevocable option to purchase the 10 patented mining claims from April 15, 2036 until April 14, 2041 (“Purchase Option 5”) for US$12,000,000, less
US$4,250,000. Of the total purchase price, US$4,000,000 may be satisfied by the issuance of First Mining Shares to the leaseholder.

● If at any time during the term of the lease, First Mining commences commercial production, the leaseholder can, by written notice, require us to purchase the 10 patented
mining claims for US$12,000,000 (the “Mandatory Purchase Right”), less any cash payments made by Gold Canyon to the leaseholder in connection with Purchase
Option  3,  Purchase  Option  4,  and  Purchase  Option  5.  Of  the  total  purchase  price,  US$4,000,000  may  be  satisfied  by  the  issuance  of  First  Mining  Shares  to  the
leaseholder.

● If we purchase the 10 patented mining claims from the leaseholder prior to the commencement of commercial production, upon achieving commercial production, we
must make a top-up payment to the leaseholder such that the leaseholder would have received an aggregate of US$12,000,000 from us for the claims (after taking into
account  any  amounts  previously  paid  in  connection  with  the  various  purchase  options).  This  top-up  payment  can  be  any  satisfied  through  any  combination  of  cash
payments and First Mining Shares.

● We must pay the leaseholder advance royalty payments on a sliding scale of US$33,000/year (2010 – 2011), US$50,000/year (2011 – 2016), US$60,000/year (2016 –
2021), US$100,000/year (2021-2031), and US$120,000/year (2031 – 2041), and all such advance royalty payments shall be deducted from any future NSR payments
made to the leaseholder.

We must pay all applicable property taxes related to the 10 patented mining claims during the term of the lease, and we maintain a right of first refusal on any sale by the
leaseholder of its interest in the claims.

Through Gold Canyon, we also have an option and lease to a further 15 patented mining claims which are fee simple parcels with mining and surface rights attached and
registered, together with the notice of option and lease, with the Land Registry Officer, Kenora, Ontario. The current term of the purchase option expires on September 9,
2023 and may be extended for successive five-year terms by delivering notice along with a renewal fee of US$50,000 and confirmation that at least $300,000 was spent on
mining  operations  in  the  prior  option  period.  We  are  required  to  make  option  payments  in  the  aggregate  amount  of  US$35,000  per  year  and  to  expend  an  aggregate  of
$300,000 on mining operations in each option term as a condition of any renewal and to pay all property taxes related to these patented claims. We have an option to acquire
the 15 claims and would be required to do so upon the commencement of commercial production at any time during the option period by payment of an aggregate of US$2
million. Upon exercise of the purchase option, we must also acquire the cabin on the property for the lesser of fair market value or US$20,000.

Underlying royalties which affect the Springpole Project are:

● 3%  NSR  on  five  patented  claims  payable  to  Jubilee  Gold  Exploration  Ltd.  (“Jubilee Gold”)  upon  commencement  of  commercial  production  with  advance  royalty
payments of $70,000 per year, adjusted using the yearly Consumer Price Index. We have an option to acquire 1% of the NSR for $1,000,000 at any time, and a right of
first refusal on any sale of the NSR. We can terminate the royalty obligations at any time by transferring the five patented claims back to Jubilee Gold;

● 3%  NSR  on  10  leased  patented  claims  payable  to  a  leaseholder  upon  commencement  of  commercial  production  with  advance  royalty  payments  on  a  sliding  scale  of
US$33,000/year (2010 – 2011), US$50,000/year (2011 – 2016), US$60,000/year (2016 – 2021), US$100,000/year (2021-2031), and US$120,000/year (2031 – 2041). We
have a right to acquire up to 2% of the NSR for US$1,000,000 per 1% (the “Buy-Back Right”). In the event that any of Purchase Options 1 to 5 are exercised, or the
Mandatory Purchase Right is exercised, the leaseholder would still retain a 3% NSR on the claims, unless the foregoing Buy-Back Right had already been exercised;

● 3% NSR on 15 patented claims (held by us pursuant to an option and lease) is payable to an optionor and leaseholder during the option term upon commencement of
commercial production or a 1% NSR if the purchase option is exercised prior to commercial production. We have a right to acquire the remaining 1% NSR by a payment
of US$500,000; and

● 3% NSR on six unpatented mining claims payable to an individual vendor upon commencement of commercial production with advance royalty payments of US$50,000

per year. We have an option to acquire all or a portion of the NSR at a rate of US$500,000 per 1% of the NSR.

We are required to purchase a vacation home owned by a vendor that is located on the Springpole Project upon commencement of commercial production.

To  keep  a  mining  claim  current,  the  mining  claim  holder  must  perform  $400  per  single  cell  mining  claim  unit  worth  of  approved  assessment  work  per  year,  or  $200  per
boundary cell mining claim unit, immediately following the initial registration date. The claim holder has two years to file one year’s worth of assessment work.

Surface rights are separate from mining rights. Should any method of mining be appropriate, other than those claims for which Crown leases were issued, the surface rights
would need to be secured.

We  entered  into  the  Silver  Stream  Agreement  with  First  Majestic  on  June  10,  2020  pursuant  to  which  First  Majestic  has  agreed  to  pay  a  total  of  US$22,500,000  to  First
Mining over three tranches for the right to purchase 50% of the payable silver produced from the Springpole Project (the “Silver Stream”). The first two tranches have been
paid  (the  first  tranche  was  paid  at  closing,  and  the  second  tranche  was  paid  in  January  2021  following  the  announcement  by  First  Mining  of  the  results  of  the  PFS  for
Springpole), consisting of an aggregate of US$6,250,000 in cash and US$11,250,000 in common shares of First Majestic (“First Majestic Shares”). First Majestic will make a
final  payment  of  US$5,000,000  (payable  US$2,500,000  in  cash  and  US$2,500,000  in  First  Majestic  Shares)  to  First  Mining  upon  the  earlier  receipt  by  First  Mining  of
approval  of  a  federal  or  provincial  Environmental  Assessment  for  the  Springpole  Project.  Following  the  commencement  of  production  at  the  Springpole  Project,  First
Majestic will make ongoing cash payments to us equal to 33% of the lesser of the average spot price of silver for the applicable calendar quarter, and the spot price of silver at
the time of delivery, subject to a price cap of US$7.50 per ounce of silver. We have the right to repurchase 50% of the Silver Stream for US$22,500,000 at any time prior to
the commercial of production. We also granted First Majestic a right of first refusal with respect to any future silver stream financings related to the Springpole Project.

History

Gold exploration was carried out during two main periods, one during the 1920s to 1940s, and a second period from 1985 to the present.

Between 1933 and 1936, extensive trenching and prospecting was conducted on the Springpole Project, including 10 short holes totalling 458.5 m. Limited trenching and
prospecting was completed in 1945.

The area remained dormant until 1985, when an airborne geophysical survey was completed over the entire claim group, and on the 30 patented claims line cutting was done
at both 30.5 m centres and 61 m centres. Subsequently, geological mapping, humus geochemistry, and ground geophysics were conducted over the grids.

From 1986 through 1989, 118 diamond drillholes were completed in seven drill phases totalling 38,349 m. In addition, during 1986 and 1987, approximately 116,119 m2 of
mechanical stripping was carried out and four petrographic reports were produced.

From 1989 through 1992, an induced polarization survey over the central portion of the Portage zone under Springpole Lake was conducted and the Springpole Project was
tested with eighteen core holes totalling 5,993 m. The majority of the drilling was conducted on the Portage zone. At the same time, a seven-core hole drill program was
completed around the east margins of Springpole Lake and lake-bottom sediment sampling of Springpole Lake east of Johnson Island was completed.

During  1995,  an  exploration  program  consisting  of  remapping  of  the  main  area,  of  some  of  the  existing  drill  core,  and  a  reinterpretation  of  the  geology  was  carried  out.
During the 1995 and 1996 programs, an additional 69 holes were drilled totalling 15,085 m on the Springpole Project proper and two drillholes on Johnson Island. By late
1996, Gold Canyon acquired 100% of the Springpole Project. Gold Canyon continued exploration in 1997 and 1998 with another 52 core holes totalling 5,643 m.

In the summer of 1998 a lake bottom sediment sampling program was conducted in several areas of the Springpole Project, which identified several follow-up targets that
were tested in 1999 with 12 core holes totalling 2,779 m.

During 2004, 2005, and 2006, diamond drilling programs were conducted on the Springpole Project by Gold Canyon, totalling over 17,322 m in 109 drillholes.

In 2007, Gold Canyon conducted an 11 diamond drillhole program that totaled 2,122 m of drilling, and in the fall of 2007, they embarked on a limited exploration program to
further investigate the Fluorite zone that was previously identified during a trenching program in 1990.

In 2008, Gold Canyon drilled a further seven core holes totaling 2,452 m.

From early August through to the end of October 2009, Gold Canyon re-logged and re-sampled a portion of the historic drill core stored at the project site and temporary tent
camp. A total of 115 drillholes were re-logged which equates to approximately 31% of the available drillholes.

In the winter of 2010, a total of six diamond drill holes were drilled for a total of 1,774.5 m of HQ drilling. During the following summer and fall of 2010, a total of 8,662 m
of diamond drilling was completed in 23 drillholes.

In 2011, Gold Canyon carried out a drill program which totaled 29,787 m in 82 diamond core holes.

A 2012 drill program began in-filling the Portage zone based upon results of the 2011 drill program. The 2012 drill program totaled 39,392 m in 98 diamond core holes.

In 2013, Gold Canyon drilled 24 diamond drill holes totaling 5,394.5 m, and 18 Vibracore holes totaling 720.8 m.

In  the  winter  of  2013,  seven  inclined  diamond  drill  holes  were  drilled  totaling  2,401.5  m.  These  holes  were  drilled  to  explore  for  additional  mineralization  outside  the
proposed pit wall and to obtain further structural and geotechnical data around the proposed open-pit area.

In June and July 2013, 17 diamond drill holes totaling 2,993 m were drilled from barges on Springpole Lake.

In  the  fall  of  2013,  18  holes  totaling  720.9  m  were  drilled  from  a  barge  on  Springpole  Lake  using  a  new  drilling  technique  that  employed  a  combination  of  standard  soil
sampling tools and sampling techniques for the very soft material and the use of Vibracore equipment to penetrate and sample the more competent sediments/rocks.

In  2013,  Gold  Canyon  commissioned  SRK  Consulting  (Canada)  Inc.  (“SRK”)  to  supervise  the  2013  geotechnical  and  structural/geological  program  and  to  complete  a
preliminary economic assessment on the Springpole Project.

On November 13, 2015, we acquired Gold Canyon, and as a result, the Springpole Project.

In October 2016 we commenced a drilling program at the Springpole Project to collect additional material for metallurgical testing. A total of four holes comprising 1,712 m
were drilled, with hole locations specifically chosen to recover sample material that is representative of the Springpole deposit. In February 2017, we announced the results of
the drilling program.

In 2017, we commissioned SRK to complete an updated PEA on the Springpole Project.

In 2018, we carried out a limited geotechnical drill program to test the integrity of ground relevant to coffer dam construction and characterize the dyke foundation materials.
Eleven short holes were drilled totaling 243 m.

In 2020, three diamond drill holes totaling approximately 1,182 m were drilled to collect additional material for metallurgical testing within the immediate vicinity of the
proposed open pit. A further 24 diamond drill holes were drilled totaling 4,091 m in order to obtain additional geotechnical data in both the pit wall area and the areas of
planned mine infrastructure. The ten holes which targeted the pit wall were also utilized to collect hydrogeological data.

Geological setting, mineralization and deposit types

The Springpole Project is located within the Archean-aged Birch-Uchi Greenstone Belt. Studies of the southern part of the Birch-Uchi greenstone belt have revealed a long,
multistage history of crustal development. Based on mapping, lithogeochemistry, and radiometric dating, the supracrustal rocks of the greenstone belt were subdivided into
three stratigraphic group-scale units (listed in decreasing age): the Balmer, Woman and Confederation assemblages. This three-part subdivision was applied to most of the
Uchi Subprovince. The Confederation assemblage is thought to be a continental margin (Andean-type) arc succession, versus the less certain tectono-stratigraphic context of
the other assemblages. Some relatively small conglomeratic units likely form a synorogenic, discontinuously distributed, post-Confederation assemblage in the Birch-Uchi
greenstone belt.

The  northern  margin  of  the  Birch-Uchi  greenstone  belt  forms  a  pattern  of  sub-regional  scale  cusps  of  supracrustal  strata  alternating  with  batholiths.  Basaltic  units  are
prominent around the periphery of the greenstone belt and may be part of the Woman assemblage but the accuracy of this stratigraphic assignment is unknown. It is suggested
that Confederation assemblage age rocks make up the bulk of the greenstone belt.

The  Springpole  Project  is  underlain  by  a  polyphase  alkali,  trachyte  intrusion  displaying  autolithic  breccia.  The  intrusion  is  comprised  of  a  system  of  multiple  phases  of
trachyte  that  is  believed  to  be  part  of  the  roof  zone  of  a  larger  syenite  intrusion;  fragments  displaying  phaneritic  textures  were  observed  from  deeper  drill  cores  in  the
southeast  portion  of  the  Portage  zone.  Early  intrusive  phases  consist  of  megacrystic  feldspar  phenocrysts  of  albite  and  orthoclase  feldspar  in  an  aphanitic  groundmass.
Successive  phases  show  progressively  finer-grained  porphyritic  texture  while  the  final  intrusive  phases  are  aphanitic.  Within  the  country  rocks  to  the  north  and  east  are
trachyte and lamprophyre dikes and sills that source from the trachyte- or syenite-porphyry intrusive system.

The main intrusive complex appears to contain many of the characteristics of alkaline, porphyry style mineralization associated with diatreme breccias (e.g. Cripple Creek,
Colorado). Direct comparison with drill core from the two sites shows a number of consistent textures and styles of mineralization. A recent observation made from drilling,
combined  with  the  airborne  magnetic  survey,  shows  that  potentially  economic  gold  mineralization  is  coincident  with  an  unexplained  geophysical  anomaly.  This  style  of
mineralization is characterized by the Portage zone and portions of the East Extension zone where mineralization is hosted by diatreme breccia in aphanitic trachyte. It is
suspected that ductile shearing and brittle faulting have played a significant role in redistributing structurally controlled blocks of the mineralized rock. Still to be identified is
a form of porphyry style alteration zoning consisting of an outer zone of phyllic (sericite) dominant alteration with narrow zones of advanced argillic alteration characterized
by illite and kaolinite, and a core zone of intense potassic alteration characterized by biotite and K-feldspar.

Mineralization at the Springpole Gold Project is dominated by large tonnage, low grade, disseminated porphyry-style or epithermal-style gold mineralization associated with
the  emplacement  of  an  alkali  trachyte  intrusion.  Textures  observed  in  the  extensive  repository  of  drill  core  appear  to  confirm  that  the  disseminated  gold-silver-sulphide
mineralization, the mesothermal to epithermal lode vein gold mineralization, and the banded iron-formation hosted gold mineralization are all the result of the emplacement
of multiple phases of trachyte porphyry and associated diatreme breccias, hydrothermal breccias, dikes and sills.

Exploration

During  the  winter  of  2019  -  2020,  we  initiated  a  program  of  core  re-sampling.  A  total  of  8,358  samples  were  collected  for  total  sulphur  assays,  along  with  611  samples
collected for bulk density determination.

We conducted several field programs throughout 2020, with the primary purpose of collecting additional data to advance the metallurgical, geotechnical, hydrogeological, and
environmental studies at the Springpole Project through PFS level and beyond. Diamond drilling was undertaken to collect samples for metallurgical and geotechnical test
work.

In addition, a detailed geotechnical field testing and sampling program was completed over the areas of proposed mine infrastructure.

A  program  of  condemnation  drilling  targeting  key  infrastructure  areas  was  also  commenced  in  2020  and  is  scheduled  for  completion  in  2021.  Additional  mapping  and
sampling of nearby trachyte outcrops was completed during the summer of 2020 and further exploration on these areas and other potential targets outside of the main resource
area will continue in 2021.

Drilling

During  the  winters  of  2007  and  2008  Gold  Canyon  conducted  drill  programs  that  completed  18  holes  totalling  4,574  m,  11  holes  totalling  2,122  m,  and  7  holes  totalling
2,452 m of diamond core drilling, respectively.

During the winter of 2010, a total of six diamond drillholes were drilled for a total of 1,774.5 m of HQ drilling. Two drillholes were not completed and both holes ended in
altered and mineralized rock. The drill program revealed a more complex alteration with broader, intense zones of potassic alteration replacing the original rock mass with
biotite and pyrite. During the summer and fall of 2010, an additional 23 diamond drill holes were drilled for a total of 8,662 m.

The 2011 drill program totaled 29,787 m in 82 diamond core holes. Five of the diamond core holes were drilled for the purpose of metallurgical testing. All these holes were
twins of previously drilled holes.

The 2012 drill program began in-filling the Portage zone based upon results of the 2011 drill program. The goal was to infill areas where Inferred Mineral Resources had been
defined in the February 2012 Mineral Resource update and to potentially expand the mineralization to the southeast. The 2012 drill program totaled 39,392 m in 98 diamond
core holes.

During 2013, Gold Canyon drilled 24 drill holes totaling 5,394.5 m, and 18 Vibracore holes totaling 720.8 m. Between January and March 2013, Gold Canyon drilled a total
of 2,401.5 m in the seven holes. Three of the drill holes encountered multiple zones of mineralization. In June and July 2013, 17 diamond drill holes totalling 2,993 m were
drilled from barges on Springpole Lake. In Fall 2013, eighteen holes totalling 720.9 m were drilled from a barge on Springpole Lake. These holes established that the Portage
zone is covered with up to 71 m of soft clay lake bottom sediments and till. The 2013 drilling program firmly established that the zone between lake bottom and the top of
bedrock is essentially barren of any significant gold and silver mineralization.

The 2016 drill program was implemented to collect additional material from the Portage zone so that additional metallurgical testing could be carried out. In total, 1,712 m
were drilled in the four holes (PM-DH-01 to 04).

In 2018, we carried out a limited geotechnical drill program to test the integrity of ground relevant to cofferdam construction and characterize the dyke foundation materials.
Eleven short holes were drilled totalling 243 m.

In 2020, three diamond drill holes totaling approximately 1,182 m were drilled to collect additional material for metallurgical testing within the immediate vicinity of the
proposed open pit. A further 24 diamond drill holes were drilled totaling 4,091 m in order to obtain additional geotechnical data in both the pit wall area and the areas of
planned mine infrastructure. The ten holes which targeted the pit wall were also utilized to collect hydrogeological data.

Sampling, analysis and data verification

Detailed descriptions of the drill core were carried out under the supervision of a senior geologist, a member in good standing of the Association of Professional Geologists of
Ontario and American Institute of Professional Geologists. The core logging was carried out on-site in a dedicated core logging facility. Drill log data from drill programs up
to 2016 were recorded onto paper logs that were later scanned and digitized. Logging of the 2018 and 2020 drill core was completed using Datamine ‘DH Logger’ software,
and data was imported directly into our central Fusion SQL drilling database.

Core was laid out 30 to 40 boxes at a time. First, the core was photographed in 15 m batches prior to logging or sampling. This was followed by a geotechnical log that
recorded quantitative and qualitative engineering data including detailed recovery data and rock quality designation. Any discrepancies between marker blocks and measured
core length were addressed and resolved at this stage. The core was then marked up for sampling.

For Gold Canyon’s 2010 and 2011 drill programs, and the 2016 – 2020 First Mining drill programs, all the drill core intervals were sampled using sample intervals of 1 m.
During the 2012 drilling program, Gold Canyon changed its standard sample length from 1 m to 2 m lengths. However, in zones of poor recovery, 1.5 m or 3 m samples were
sometimes collected. Samples over the standard sample length were typically half core samples and whole core was generally only taken in intervals of poor core recovery
across the sampled interval. Sampling marks were made on the core and sample tickets were stapled into the core boxes at the beginning of each sample interval.

Quality control samples were inserted into the sample stream. Inserting quality control samples involved the addition of certified blanks, certified gold standards, and field
and laboratory duplicates. Field duplicates were collected by quartering the core in the sampling facility on-site. Laboratory duplicates were collected by splitting the first
coarse reject and crushing and then generating a second analytical pulp. Blanks, standards, and duplicates made up on average 10% of the total sample stream. Sample tickets
were marked blank, field or laboratory duplicate, or standard, and a sample tag was stapled into the core box within the sample stream.

Geological descriptions were recorded for all core recovered. Separate columns in the log allow description of the lithology, alteration style, intensity of alteration, relative
degree of alteration, sulphide percentage, rock colour, vein type, and veining density. A separate column was reserved for written notes on lithology, mineralization, structure,
vein orientations/relations etc. The header page listed the hole number, collar coordinates, final depth, start/end dates, and the name of the core logging geologist.

Following the logging and core marking procedures described above, the core was passed to the sampling facility. Core sampling was performed by experienced sampling
technicians (for Gold Canyon’s drill programs, technicians were from Ackewance Exploration & Services of Red Lake, Ontario), or on-site geologists, and quality control
was  maintained  through  regular  verification  by  on-site  geologists.  Core  was  broken,  as  necessary,  into  manageable  lengths.  Pieces  were  removed  from  the  box  without
disturbing the sample tags, were cut in half lengthwise with a diamond saw, and then both halves were carefully repositioned in the box. When a complete hole was processed
in this manner, one half was collected for assay while the other half remained in the core box as a witness. The remaining core in the boxes was then photographed. All logs
and photographs were then submitted to the senior geologist/project manager for review and were archived. Data were backed up.

The sampling technician packed one half of the split core sample intervals into transparent vinyl sample bags that were sequentially numbered to match the sample number
sequences in the sample tag booklets used by the core-logging geologists. The numbered, blank portion of the triplicate sample tag was placed in the bag with the sample; the
portion  that  was  marked  with  the  sample  interval  remained  stapled  into  the  bottom  of  the  core  box  at  the  point  where  the  sample  interval  begins.  Sample  bags  were  then
sealed with plastic tags. Sealed sample bags were packed into rice sacks five samples at a time. All sacks were individually labeled with the name of the company, number of
samples  contained  therein,  and  the  number  sequence  of  the  samples  therein.  Sacks  were  assigned  sequential  numbers  on  a  per  shipment  basis.  A  project  geologist  then
checked the sample shipment and created a shipping manifest for the sample batch. A copy was given to the project manager and a copy was sent along with the sample
shipment. A copy of the sample shipment form was also sent via e-mail to the analytical laboratory.

The  project  geologist  prepared  the  sample  submission  form  for  the  assay  laboratory.  This  form  identified  the  number  of  sample  sacks  as  well  as  the  sequence  of  sample
numbers to be submitted. Due to the remote location, the shipment was then loaded on to a plane or helicopter and flown direct to Red Lake where representatives of the
commercial analytical laboratory met the incoming flight and took the samples to the laboratory by pickup truck.

Once at the laboratory, a manager checked the rice sacks and sample numbers on the submission form. The laboratory then split the received sample manifest into batches for
analysis, assigned a work order to the batch, and sent a copy of the mineral analysis acknowledgement form to the project manager.

Aluminum tags embossed with the hole number, box number, and box interval (from/to) were prepared and stapled onto the ends of each core box. Core boxes were cross
stacked on pallets and then moved to on-site storage.

Core  samples  collected  at  the  drill  site  were  held  in  closed  core  boxes  sealed  with  fiber  tape;  at  various  times  of  day,  camp  staff  collected  the  core  boxes  that  were  then
delivered to the core logging facility. All core logging, sampling and storage took place at the Springpole Project site. Following the logging and marking of core, all core
preparation and sampling was performed by technicians (for Gold Canyon’s drill programs, technicians were from Ackewance of Red Lake, Ontario) under the supervision of
the project manager, or by company geologists. All on-site sampling activities were directly supervised by the project manager or geologist.

All gold assay work since the 2010 drill program has been performed by SGS Laboratories in Red Lake, Ontario. Silver and multi-element assays for the Gold Canyon drill
programs were performed by the SGS Don Mills laboratory in Toronto, Ontario, and by the SGS laboratory in Vancouver for our 2016 and 2020 drill programs. The SGS
facilities are certified and conform to requirements CAN-P-1579 and CAN-P-4E (ISO/IEC 17025:2005). Certification is accredited for precious metals including gold and
silver and 52 element geochemical analyses.

We  have  attested  that  there  is  no  commercial  nor  other  type  of  relationship  between  us  and  SGS  Laboratories  that  would  adversely  affect  the  independence  of  SGS
Laboratories.

All  samples  received  by  SGS  Red  Lake  were  processed  through  a  sample  tracking  system  that  is  an  integral  part  of  the  company’s  laboratory  information  management
system. This system utilizes bar coding and scanning technology that provides complete chain of custody records for every stage in the sample preparation and analytical
process.

Samples were dried, and then crushed to 70% of the sample passing 2 mm (-70 mesh). A 250 g sample was split off the crushed material and pulverized to 85% passing 75
microns (200 mesh). A 30 g split of the pulp was used for gold fire assay and a 2 g split was used for silver analysis. Crushing and pulverizing equipment was cleaned with
barren wash material between sample preparation batches and, where necessary, between highly mineralized samples. Sample preparation stations were also equipped with
dust extraction systems to reduce the risk of sample contamination. Once the gold assay was complete, a pulp was sent to the SGS Toronto facility for silver and possibly for
multi-element geochemical analysis.

As  part  of  the  standard  internal  quality  control  procedures  used  by  the  laboratory,  each  batch  of  75  Springpole  Project  core  samples  included  four  blanks,  four  internal
standards, and eight duplicate samples. In the event that any reference material or duplicate result would fall outside the established control limits, the sample batches would
be re-assayed.

Pulps and rejects from the core samples, as well as from earlier drill programs where still available, are currently being kept in storage by First Mining.

Prepared samples were analyzed for gold by fire assay with atomic absorption finish. Samples returning assays in excess of 10g/t gold were re-analyzed with a gravimetric
finish.

Prepared pulp samples shipped from SGS Red Lake to SGS Toronto were analyzed for silver by three-acid digestion with atomic absorption finish.

During the winter 2010 program, prepared samples were analyzed for 52 elements by acid digestion (3:1 HCl: HNO3).

All samples from the 2016 and 2020 drill programs by us were also analyzed for 52 elements by acid digestion.

The QA/QC program for 2003 to 2007 consisted of:

●

●

●

resubmission of approximately 10% of the sample pulps to a second laboratory (ALS Chemex).

insertion of two commercial standard reference materials (standards submitted every 30th sample)

insertion of blanks

A  total  of  18  drill  holes  were  completed  in  2007  and  2008  comprising  a  total  of  1,374  assay  intervals.  These  samples  were  assayed  for  gold  only  by  the  Accurassay
Laboratories of Thunder Bay, Ontario. SRK checked a total of 137 samples representing 10% of the total against the original certificates. No errors were found.

No program was set up for duplicates, standards, or blanks for this drilling program. The laboratory ran their own set of duplicates for internal monitoring purposes; however,
those data were not available to SRK.

In 2010, Gold Canyon instituted a QA/QC program consisting of commercial standard reference materials for gold, and, consistent with current industry practice, blanks, field
duplicates, and pulp duplicates. In addition, a “round robin” program was instituted in 2011 with ACT Labs of Red Lake, Ontario, that compared pulp re-assay results against
the original SGS results for 469 samples. SGS conducted their own program of internal duplicate analysis as well.

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
For the First Mining QA/QC programs from the 2016 and 2020 drilling, blanks and standards were inserted at a rate of one standard for every 20 samples (5% in total), and
one blank for every 30 samples (3% in total). ‘Coarse’ duplicates and ‘pulp’ duplicates were also inserted at regular intervals with an insertion rate of 4%. For the 2020 assay
program, field duplicates from quartered core were also inserted at regular intervals, with an insertion rate of 4%.

In addition to the QA/QC program implemented by First Mining, the laboratories operate their own internal laboratory QA/QC system, inserting quality control materials,
blanks, laboratory replicates and laboratory duplicates on each analytical run.

Of the 18 drillholes completed in 2007 and 2008, comprising a total of 1,374 assay intervals analyzed for gold, SRK checked a total of 137 samples representing 10% of the
total against the original certificates. No errors were found.

A total of 3,135 assay values for gold and 3,161 assay values for silver in the database were compared against the original protected PDF assay certificates submitted by SGS
Red Lake. These totals represent 10.1% and 10.4% of the total number of assays for gold and silver, respectively.

Of the original assay values checked against certificates, the focus was on values material to any resource estimate, either higher-grade intervals or very low-grade intervals in
proximity to higher-grade intervals. The average grade of gold samples verified was 2.05 g/t Au. The average grade of silver samples checked was 8.27 g/t Ag.

Only two errors were found for gold:

●

●

The gold value of sample interval SP10-028 from 433 m to 436 m (sample number 8287) was found to have an entered value of 5.96 g/t gold against a value on the
assay certificate of 9.00 g/t gold.

The  gold  value  of  sample  interval  SP11-076  from  69  to  70  m  (sample  number  14583)  having  the  value  of  0.45  oz./t  was  incorrectly  placed  in  the  parts  per  billion
column.

No errors were found with respect to silver assays.

This represents an error rate of 0.064% in gold assays and an error rate of 0.0% in silver assays. This error rate is well within acceptable industry standards.

As part of the Mineral Resource estimation process, SRK reviewed the QA/QC data collected by Gold Canyon, reviewed the procedures in place to assure assay data quality,
and verified the assay database against original assay certificates provided directly to SRK by SGS Red Lake, the assay laboratory. A total of 53,431gold assays, 46% of the
assay  data,  were  checked  against  original  assay  certificates.  No  significant  database  errors  were  identified.  About  143  minor  rounding  errors  were  observed.  None  of  the
rounding errors are deemed material or of any significance to the Mineral Resource estimate presented in the report.

During 2020, we completed a comprehensive comminution and metallurgical testwork program to support the PFS. This included head grade analyses, mineralogy, a full suite
of comminution, flotation, and leach tests; cyanide detoxification, rheology, and solid/liquid separation. Testwork was conducted by SGS Lakefield, Canada in two phases:
Phase 1 used available coarse reject material from the 2016 drilling campaign and Phase 2 used fresh HQ drill core from the 2020 winter drilling campaign.

Tests were performed on mineralization that is considered to be representative of plant feed, based on a recent mine plan. Composite samples representing major lithologies
and a range of head grades were prepared (0.60 to 2.0 g/t Au and 0.5 to 20 g/t Ag). The minimum and maximum grades aligned with expected plant feed for the first nine
years of production.

Bulk  mineralogy  on  select  composites  showed  the  main  sulphide  mineral  was  pyrite,  ranging  from  5.3  to  7.7%,  with  traces  of  chalcopyrite,  sphalerite,  and  galena.  Gold
deportment studies indicated 5 to 12% of the gold is sub-microscopic; 8 to 14% of the gold is locked in <11 µm size fractions; 42 to 64% of the gold is exposed and 22 to
32% is liberated. A host of telluride minerals exist in the microscopic size range, with petzite the most dominant. Gold and electrum occur in minor amounts.

Comminution testing showed that the materials tested are considered very soft to medium in competency, with SMC test A*b values ranging from 40 to 124 and SPI test
results from 7 to 67 min. Conventional Bond tests showed significant variation in hardness, with Bond rod mill work indices ranging 9 to 15 kWh/t and Bond ball mill work
indices ranging from 8 to 18 kWh/t, at a closing screen size of 150 µm.

Two  parallel  flowsheets  were  evaluated,  following  the  results  from  the  previous  studies:  flotation  +  concentrate  and  tailings  leaching  versus  whole  ore  leaching.  The
recommended flowsheet for this study is flotation with concentrate/tailings leaching.

40

 
 
 
 
 
 
 
 
 
 
 
 
Whole ore cyanide leach tests showed relatively poor extraction at a grind size of 80% passing 75 µm or greater using aggressive leach conditions to combat the effects of the
telluride minerals. Gold leach extractions ranged from 52 to 72%. At a finer grind of 80% passing 60 µm, gold extractions ranged from 64 to 84%.

Rougher flotation tests showed high sulphide recovery was generally achieved within eight minutes. Excessive foaming was observed in some samples. This was considered
attributable to a drilling compound added to the core, to aid core recovery (this was also commented on in the 2019 updated PEA report for the Springpole Project, which
tested  samples  from  the  same  drilling  program).  High  mass  pull  was  observed  in  these  samples.  A  cleaning  stage  reduced  the  mass  pull  reporting  to  concentrate  regrind.
Flotation recoveries to cleaner concentrate ranged from 55 to 83% for gold, 55 to 90% for silver and 75 to 98% for sulphur at a target mass pull of 15% or less. Leaching of
flotation tails is required to attain acceptable gold recovery. Tailings samples showed very high leach extractions in general.

Flotation  concentrate  gold  extraction  showed  significant  benefit  from  finer  regrinding  to  an  80%  passing  size  of  15  to  17  µm.  Particularly  high  concentrate  leach  residue
grades were observed at 80% passing 25 µm. Flotation concentrate gold extractions ranged from 62 to 97%, somewhat dependent on gold head grade. Flotation tails gold
extractions ranged from 52 to 94%.

Overall plant gold recoveries are predicted to average 86% for head grades of 0.8 to 1.22 g/t Au. Overall plant recoveries for silver are predicted to range from 85 to 92% for
head grades of 3.2 to 8.3 g/t Ag.

Cyanide detoxification tests achieved <1 mg/L CNWAD, with favourable reagent consumption rates.

Mercury  grades  were  in  the  range  of  <0.3  to  8  g/t  in  the  flotation  feed. A  retort  with  gas  collection  system  was  incorporated  into  the  plant  design  to  manage  and  control
mercury in the process. Arsenic is present in the feed at concentrations up to 30 g/t and is not expected to be problematic in processing. No other elements were noted that
may cause issues in the process plant or concerns with product marketability.

Thickening  and  filtration  of  cyanide  detoxified  slurry  showed  a  moisture  content  of  18.5%  (by  weight)  was  achieved  with  high-rate  thickening  followed  by  pressing  and
drying using a conventional plate and frame filter press. A moisture content of 15% was achieved when employing a membrane squeeze in addition to pressing and drying in
a plate and frame filter.

The  authors  of  the  Springpole  Technical  Report  make  the  following  recommendations:  (i)  future  drilling  should  be  done  using  drill  mud  additives  that  have  been
demonstrated  to  have  minimal  impact  on  metallurgical  testwork  (a  bulk  sample  might  be  considered  to  avoid  the  issue  of  drilling  compound  modifying  reagents);
(ii) investigate the impact of drilling mud additives on flotation mass pull with the objective of reducing flotation circuit size and regrind power requirements; (iii) further
optimize concentrate leach reagents and consider reductions in leach extraction time (this includes reducing the number of concentrate leach adsorption tanks and recover
residual gold/silver in solution using the flotation tails CIP circuit); (iv) optimize combined tails residual cyanide levels and aim to reduce cyanide detoxification retention
time; and (v) conduct a full Feasibility Study metallurgical testwork program incorporating variability and production composite testwork (this includes dewatering/filtering
tests on the final tailings material).

Mineral resource estimates

There  are  662  drillholes  in  the  Springpole  Project  database.  The  Mineral  Resource  estimate  for  the  Springpole  Project  utilizes  results  from  404  core  boreholes  drilled  by
previous owners of the property during the period of 2003 to 2013, and seven holes drilled by us in 2016 and 2020.

The revised Mineral Resource estimate was based on a gold price of US$1,550/oz and a silver price of US$20/oz, both considered reasonable economic assumptions by SRK.
To establish a reasonable prospect of economic extraction in an open pit context, the resources were defined within an optimized pit shell with pit walls set at 35° to 50° based
on  domains.  Assumed  metallurgical  recoveries  of  88%  for  gold  and  93%  for  silver  were  used.  Mining  costs  were  estimated  at  $1.62/t  of  total  material,  processing  costs
estimated at $15.38/t, and general and administrative (“G&A”) costs estimated at $1.00/t. A cut-off grade (“COG”) of 0.3 g/t Au was calculated and is considered to be an
economically reasonable value corresponding to breakeven mining costs. Approximately 90% of the revenue for the proposed project is derived from gold, with 10% derived
from silver.

The updated resource estimate is summarized in the table below.

Mineral  Resources  that  are  not  Mineral  Reserves  do  not  have  demonstrated  economic  viability.  The  estimate  of  Mineral  Resources  may  be  materially  affected  by
environmental,  permitting,  legal,  title,  taxation,  sociopolitical,  marketing,  or  other  relevant  issues.  The  quantity  and  grade  of  reported  Inferred  Mineral  Resources  in  this
estimation  are  uncertain  in  nature  and  there  has  been  insufficient  exploration  to  potentially  convert  some  or  all  of  these  Inferred  Mineral  Resources  as  an  Indicated  or
Measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to the Indicated or Measured Mineral Resource category. SRK is of the
opinion that further attempts to convert the remaining Inferred material to Indicated would be of questionable value. The current proportion of the Mineral Resource classified
as Inferred Mineral Resources is 10% of total tonnes, and 6% of contained gold.

Report mine plan. Indicated Mineral Resources in the mine plan were converted directly to Probable Mineral Reserves. There are currently no Measured Mineral Resource

*This Mineral Reserve estimate is as of December 30, 2020 and is based on the new Mineral Resource estimate dated July 30, 2020. The Mineral Reserve calculation was
completed under the supervision of Gordon Zurowski, P.Eng of AGP, who is a Qualified Person as defined under NI 43-101. Mineral Reserves are stated within the final
design pit based on a US$878/ounce gold price pit shell with a US$1,350 /ounce gold price for revenue. The equivalent cut-off grade was 0.34 g/t Au for all pit phases. The
mining cost averaged $2.75/tonne mined, processing averages $14.50/tonne milled, and G&A was $1.06/tonne milled. The process recovery for gold averaged 88% and the
silver recovery was 93%. The exchange rate assumption applied was $1.30 equal to US$1.00.

*Pit slope angles ranged from 35 - 50°.

The Mineral Reserves for the Springpole Gold Project are based solely on open pit mining assumptions.

The  Qualified  Person  responsible  for  the  preparation  of  the  Mineral  Reserve  estimates  in  the  Springpole  Technical  Report  has  not  identified  any  known  legal,  political,
environmental, or other risks that would materially affect the potential development of the Mineral Reserves. The risk of not being able to secure the necessary permits from
the government for development and operation of the Springpole Project exists but the Qualified Person is not aware of any issues that would prevent those permits from
being withheld per the normal permitting process.

Mining methods

The PFS is based on open pit mining of the proposed Springpole pit. This pit will provide feed material necessary to maintain the process plant feed rate at 30,000 tpd while
operational.

The Springpole pit will be a three phased pit which will provide 121.6 Mt of ore grading 0.97 g/t Au, and 5.23 g/t Ag. Waste from this pit will total 275.4 Mt for a strip ratio
of 2.3:1 (waste:ore). With the inclusion of the proposed quarry, the total waste movement will be 287.5 Mt for a life-of-mine (“LOM”) strip ratio of 2.36:1 (waste:ore)

In addition to the pit, a quarry would be established near the plant location in the pre-production period. This quarry would be used to construct mine infrastructure including
haul roads, cofferdams and to meet site fill requirements for other infrastructure.

The mill feed cut-off used is 0.40 g/t Au. During the mine operation material would be stockpiled to optimize the plant feed grade and defer lower-grade material until later in
the mine schedule. The three grade bins used for the stockpiles included: low grade (0.40 to 0.60 g/t Au), medium grade (0.60 to 0.80 g/t Au) and high grade (over 0.80 g/t
Au).

43

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  phases  are  scheduled  to  provide  30,000  tpd  of  feed  to  the  mill  over  an  11.3  year  mine  life  after  three  years  of  pre-production  stripping.  The  first  two  years  of  pre-
production stripping are construction related. The last three years of mining are stockpile reclaim. The pits are sequenced to minimize initial stripping and provide higher feed
grades in the early years of the mine life which the stockpiling strategy accomplishes.

The pits will be built on 12 m benches with safety berms placed every 24 m. Inter-ramp angles vary from 39 to 54° in rock depending upon the wall orientation. Overburden
will use a 30° inter-ramp angle with 12 m between berms. Minimum mining widths of 35 to 40 m were maintained in the design with preferred bench widths of 60 m or more.
Ramps will be at maximum 10% gradient and vary in width from 27.1 m (single lane width) to 35.4 m (double lane width). They have been designed for a 226 t haulage
truck.

The main fleet will consist of three 251 mm rotary drills, two 36 m3 electric hydraulic shovels and one 23 m3 front-end loader. The truck fleet will total seventeen 240 t trucks
at the peak of mining. This is due to the long hauls from the pit to the waste storage facilities (“WSF”) as well as the backhaul of tailings material from the plant. The usual
assortment of dozers, graders, small backhoes, and other support equipment is considered in the equipment costing. A smaller front-end loader (13 m3) will be stationed at the
primary crusher.

In the pre-production years -3 and -2, 3.9 Mt will be mined within the quarry area. This mining will be with 91 t trucks, 6 m3 excavators and smaller track drills, more suited
to  this  type  of  work,  preparing  the  site  for  the  larger,  more  productive,  equipment.  Year  -1  is  the  start  of  major  mining  activity  using  the  larger  equipment  when  the  bay
dewatering has advanced sufficiently for mining and the site infrastructure (power lines, roads, etc.) is in place. The early phases provide the highest grade to the mill early in
the schedule. The open pit will be in operation until Year 9 followed by three years of stockpile reclaim to feed the plant. When the open pit is complete, the larger mining
fleet will move to complete the quarry area, dumping the material into the open pit. This will serve to cover the slopes in the pit for reclamation purposes.

Waste material from the pit will be stored in the WSF. Non-acid generating (“NAG”) material will be used for the outer berms while potentially acid generating material will
be co-mingled with filtered tails. The filtered tails will be backhauled from trucks returning from dropping material at the plant either as feed or placed in the stockpiles. As
the WSF advances upwards, re-sloping of the sides will be occurring to allow for concurrent reclamation and reducing the visual impact of the facility. The majority of the
waste rock will be contained within the WSF (196.6 Mm3), but a small portion of NAG material will be backfilled into Phase 2 of the open pit near the end of the mine life.
This will reduce the overall haul length and will help in pit reclamation. A total of 9.8 Mm3 will be backfilled into the pit.

Processing and recovery operations

The process plant will be designed using conventional processing unit operations. It will treat 30,000 tpd or 1,250 t/h based on an availability of 8,059 hours per annum or
92%. The crusher plant section design is set at 75% availability and the gold room availability is set at 52 weeks per year including two operating days and one smelting day
per week. The plant will operate with two shifts per day, 365 days per year, and will produce gold doré bars.

The plant feed will be hauled from the mine to a crushing facility that will include a gyratory crusher as the primary stage before being conveyed to the crushed ore stockpile.
The crushed ore will be ground by a SAG mill, followed by a closed circuit of a ball mill with a hydro-cyclone cluster. The hydro-cyclone overflow with P80 of 150 mesh
(106 µm) will flow to a three-stage flotation circuit including rougher flotation, rougher scavenger flotation, and cleaner flotation. Flotation tailings will report to the tailings
leaching and CIP circuit. Flotation concentrate will report to a closed loop cyclone cluster and IsaMill before reporting to the concentrate leach and CIP circuit.

Gold and silver leached in the CIP circuits will be recovered onto activated carbon and eluted in a pressurized Anglo American Research Laboratory style elution circuit and
then recovered by electrowinning in the gold room. The gold-silver precipitate will be dried in a mercury retort oven and then mixed with fluxes and smelted in a furnace to
pour doré bars. Carbon will be re-activated in a carbon regeneration kiln before being returned to the CIP circuits. CIP tails will be treated for cyanide destruction prior to
pumping to a final tails thickener and pressure filter. Filter cakes will be hauled to the WSF for disposal.

The installed power for the process plant will be 58 MW and the power consumption is estimated to be 32 kWh/t processed. Raw water will be pumped from Birch Lake to a
raw-water storage tank. Potable water will be sourced from the raw-water tank and treated in a potable water treatment plant. Gland water will be supplied from the raw-water
tank. Process water will primarily consist of water reclaimed from the final tails thickener and pressure filters. Reagents will include pebble lime, sodium cyanide, sodium
hydroxide, copper sulphate pentahydrate, hydrochloric acid, sodium metabisulphite, activated carbon, flocculant, coagulant, collector, and frother. The selected flowsheet is
shown in the below figure.

Infrastructure, permitting and compliance activities

Key  project  infrastructure  as  envisaged  in  the  PFS  includes:  open  pit  mine  area  including  mine  haul  roads  and  ramps;  cofferdams  for  hydraulic  isolation  of  the  mine  pit
following  bay  dewatering;  site  main  access  roads,  administrative  access  roads  and  maintenance  roads,  site  main  gate  and  guard  house;  administration  and  dry  building,
construction  and  permanent  camp  accommodations;  process  plant  e-room;  crushing  area  e-room;  control  room;  reagent  storage  building;  gold  room;  assay  laboratory  and
sample preparation area; plant workshop and warehouse; truck shop and warehouse, tire changing facility, truck wash building; fuel facility, fuel storage and dispensing; fresh
water intake; 230 kV overland and 25 kV underground power distribution lines; fresh water intake pumping supply and treatment; WSF, contact water collection ponds; waste
water treatment plant and explosives magazine.

The main access road will be a private extension of the existing Wenesaga Road which is primarily used for forestry services and has been constructed up to 15 kilometres
from the project site.

Approximately 58 MW of electrical demand will be supplied via a new 230 kV overhead transmission line, built to connect to the provincial grid’s 230 kV line approximately
75 km to the southeast. A 230kV / 25kV transformer will provide step down prior to feeding a total of six electrical rooms. Variable frequency drives have been allowed
where required and all medium-voltage motors or drives will be supplied in 4.16 kV.

Two  cofferdams  will  be  constructed  to  isolate  the  area  of  the  proposed  open  pit  and  facilitate  mining  following  dewatering.  A  secant  pile  wall  and  grout  curtain  will  be
installed within the rockfill to establish a hydraulic barrier.

A single WSF will be constructed west of the open pit for storage of tailings produced from mineral processing and PAG waste rock generated from open pit mining. The
WSF will store approximately 76 Mm3 of tailings and 41 Mm3 of PAG waste rock within a cell. Structural stability of the facility will be provided by perimeter embankment
dams constructed with NAG waste rock generated from open pit mining. Surface water run-off from the facility will be removed and stored in a contact water management
pond (CWMP), to be located south of the WSF, to limit infiltration of water into the waste materials following placement. An engineered cover is conservatively considered
in closure, to promote surface run-off and limit seepage, and will be further evaluated through the Environmental Assessment (EA) process.

First Mining and its predecessor Gold Canyon have been collecting environmental baseline data to support the project’s EA since 2010, and data collection is ongoing. These
studies are primarily focused on characterizing biological and physical components of the aquatic and terrestrial environments that may be impacted by and may interact with
the proposed Springpole Project. The dataset compiled to date within these programs exceeds the level of environmental baseline data one would typically have in support of
a PFS.

The area of Springpole Lake that will be dewatered spans approximately 150 hectares and displays significant variation in lakebed elevation, with the deepest point reaching
an approximate maximum depth of 40 m (El. 353 masl). This activity will affect fish habitat. First Mining will continue working with Fisheries and Oceans Canada (DFO) to
develop off-setting measures that will help to mitigate any short or long-term effects to local fish communities.

First  Mining  will  fully  consider  the  concerns  and  issues  associated  with  potential  adverse  environmental  effects,  as  appropriate,  to  the  Indigenous  peoples  in  terms  of
proximity, historic resources, land and resource use, physical and social effects (including health) on their communities, as well as economy, employment, cultural heritage, in
the EA process.

Preliminary environmental design criteria have been developed for project features that have the potential to release contaminants into the air, water, and land. First Mining
will  also  develop  an  environmental,  health  and  safety  (“EHS”)  management  system  to  address  the  EHS  needs  of  the  Springpole  Project  based  on  the  results  of  the
Environmental Impact Statement.

On February 23, 2018, we submitted a Project Description to the Impact Assessment Agency of Canada (the “IAAC”). IAAC determined an EA is required for the Springpole
Project under the Canadian Environmental Assessment Act (2012) (“CEAA”). We have also entered into a voluntary agreement with the Ontario Ministry of Environment,
Conservation and Parks to undertake an Individual EA under Section 3.0.1 of the provincial Environmental Assessment Act.

We plan to submit an EIS for the Springpole Project by the end of 2021. The EIS would be developed to also meet the regulatory requirements associated with the provincial
voluntary agreement to undertake an individual EA.

In addition to the requirement for assessment under CEAA, 2012, key federal permits that may be required pending further regulatory advice:

●  Fisheries Act Authorization (Fisheries and Oceans Canada (DFO))

●  Canadian Navigable Waters Act (Transport Canada)

●  Schedule 2 of Metal and Diamond Mining Effluent Regulations (MDMER)

Prohibitions  under  other  pieces  of  federal  legislation  also  apply  but  no  permitting  requirements  are  currently  expected.  These  may  include,  but  would  not  necessarily  be
limited to, the following:

●  Canadian Environmental Protection Act, SC 1999

●  Migratory Birds Convention Act, SC 1994, c22

●  Explosives Act, RSC 1985, C. E-17

●  Transportation of Dangerous Goods Act, SC 1992, c. 34

●  Species at Risk Act, SC 2002; c. 29

●  Nuclear Safety Control Act, SC 1997, c. 9)

Capital and operating costs

The cost estimate for the Springpole Project is based on an engineering, procurement, and construction management (“EPCM”) implementation approach.

Operating Costs

The  operating  costs  for  a  mine  at  the  project  have  been  estimated  from  base  principles  with  vendor  quotations  for  repair  and  maintenance  costs  and  other  suppliers  for
consumables. Key inputs to the mine cost are fuel and labour. The price provided for the project was $0.80/L (US$0.60/L) delivered to the site. The mine truck and support
equipment  fleets  will  be  diesel  powered.  The  large  production  drills,  hydraulic  shovels  and  dewatering  pumps  will  be  electric  powered,  and  the  cost  estimate  used  an
electricity price of $0.08/kWh (US$0.06/kWh).

Labour costs are based on an owner-operated scenario whereby we would be responsible for the maintenance of the equipment with our own employees.

The mining fleet will be leased to help lower capital costs and payments are included in the operating cost. The mining cost is shown as both cost per tonne mined and cost
per tonne moved. This is due to the large quantity of tailings backhaul included in the operating cost. The cost per tonne mined is $2.75/t mined (US$2.06/t mined) or $1.94/t
moved (US$1.46/t moved). The cost per tonne milled over the LOM is $8.69/t milled (US$6.52/t milled).

The annual process operating cost is estimated at $158.8 M (US$119.1 M) and will average $14.50/t milled (US$10.87/t milled) over the LOM. 

The G&A cost is estimated at $11.57 M (US$8.68 M) and will average $1.06/t milled (US$0.79/t milled) over the LOM.

The  capital  cost  estimate  has  an  accuracy  of  -20%  /  +30%  (AACE  Class  4).  The  estimate  includes  the  cost  to  complete  the  design,  procurement,  construction,  and
commissioning  of  all  the  identified  facilities.  The  estimate  was  based  on  the  traditional  EPCM  approach  where  the  EPCM  contractor  would  oversee  the  delivery  of  the
completed project from detailed engineering and procurement to handover of a working facility.

The  estimate  was  derived  from  a  several  fundamental  assumptions  as  indicated  in  process  flow  diagrams,  general  arrangements,  mechanical  equipment  list,  electrical
equipment list, material take offs, electrical layouts, scope definition and a work breakdown structure. The estimate included all associated infrastructure as defined by the
scope of work.

Economic Analysis

The mine plan is based on Indicated Mineral Resources that have been converted to Probable Mineral Reserves.

An economic model was developed to estimate annual pre-tax and post-tax cash flows and sensitivities of the Springpole Project based on a 5% discount rate. It must be
noted that tax estimates involve complex variables that can only be accurately calculated during operations and, as such, the after-tax results are approximations. A sensitivity
analysis was performed to assess the impact of variations in metal prices, head grades, initial capital cost, total operating cost, foreign exchange rate, and discount rate.

The capital and operating cost estimates developed specifically for the Springpole Project are in Canadian dollars and converted with the stated exchange rate. The economic
analysis has been run on a constant dollar basis with no inflation.

The economic analysis was performed using the following assumptions:

●            gold price of US$1,600/oz, silver price of US$20/oz
●            LOM of 11.3 years
●            exchange rate of US$0.75 per $1.00
●            cost estimates in constant Canadian dollars with no inflation or escalation
100% ownership with 1.3% NSR; (assumes buy back of 1.4% NSR)
● 
●            capital costs funded with 100% equity (no financing costs assumed)
●            closure cost of US$29 M
● 
●            Ontario applies a mining tax rate of 10%
●            total undiscounted tax payments are estimated to be US$720 M over the LOM

Canadian corporate income tax system consists of 15% federal income tax and 10% provincial income tax

The pre-tax net present value (“NPV”) discounted at 5% is US$1,482 M; the IRR is 36.4%; and the payback period is 2.2 years. On an after-tax basis, the NPV discounted at
5% is US$995 M; the IRR is 29.4%; and the payback period is 2.4 years.

Exploration, development and production

As discussed above, during the winter of 2019 - 2020, we initiated a program of core re-sampling in order to quantify the sulphur content of the in-pit material. A total of
8,358 samples were collected for total sulphur assays, along with 611 samples collected for bulk density determination.

We completed several field programs throughout 2020, with the primary purpose of collecting additional data to advance the metallurgical, geotechnical, hydrogeological, and
environmental studies at the Springpole Project through PFS level and beyond. Diamond drilling was undertaken to collect samples for metallurgical and geotechnical test
work.

The geotechnical program targeting the pit wall area consisted of drilling and logging of inclined HQ size boreholes, packer tests, fracture surveys using acoustic televiewer,
rock testing (point load tests and Brazilian tests), and multi-level piezometer installation.

In addition, a detailed geotechnical field testing and sampling program was completed over the areas of proposed mine infrastructure, which included test pit excavations (for
overburden investigation), hand auguring, NQ-size borehole drilling, and ground penetrating radar surveys in selected locations.

A  program  of  condemnation  drilling  targeting  key  infrastructure  areas  was  also  commenced  in  2020  and  is  scheduled  for  completion  in  2021.  Additional  mapping  and
sampling of nearby trachyte outcrops was completed during the summer months and further exploration on these areas and other potential targets outside of the main resource
area will continue in 2021.

Technical report

The  description  in  this  section  of  our  Cameron  gold  project  (the  “Cameron  Project”)  is  based  on  the  project’s  technical  report:  Technical  Report  on  the  Cameron  Gold
Deposit, Ontario, Canada (effective date January 17, 2017) (the “Cameron Gold Technical Report”). The report was prepared for us by Optiro Pty Ltd. in accordance with NI
43-101 under the supervision of Mark Drabble, B. App. Sci. (Geology), MAIG, MAusIMM; and Kahan Cervoi, B. App. Sci (Geology), MAIG, MAusIMM; each Qualified
Persons within the meaning of NI 43-101. The following description has been prepared under the supervision of Hazel Mullin, P.Geo., who is a Qualified Person within the
meaning of NI 43-101, but is not independent of us.

The conclusions, projections and estimates included in this description are subject to the qualifications, assumptions and exclusions set out in the Cameron Gold Technical
Report, except as such qualifications, assumptions and exclusions may be modified in this AIF. We recommend you read the Cameron Gold Technical Report in its entirety to
fully understand the project. You can download a copy from our SEDAR profile (www.sedar.com), or from our website (www.firstmininggold.com).

Project description, location and access

The Cameron Project is wholly-owned by us through our wholly-owned subsidiary, Cameron Gold. The Cameron Project comprises 1,790 mining claims, 24 patented claims,
seven licences of occupation and four mining leases. All of the claims are located within unsurveyed crown lands, and are situated in the Rowan Lake, Heronry Lake, Tadpole
Lake, Brooks Lake, Lawrence Lake, Bluffpoint Lake, and Dogpaw Lake areas, and the Phillips and Godson townships.

The total area of the project is approximately 495.74 km2 (49,574 ha).

The Cameron Project currently consists of two project areas; namely Cameron (which includes the Cameron deposit) (the “Cameron Deposit”) and West Cedartree (which
includes  the  Dubenski  and  Dogpaw  deposits).  The  Cameron  Gold  Technical  Report  covers  only  the  Cameron  Deposit  and  Mineral  Resource  Estimate  within  the  broader
Cameron Project. The Cameron Project area comprises 1,699 mining claims, four patented claims, six licences of occupation and three mining leases. The West Cedartree
property comprises 91 mining claims, 20 patented claims, one licence of occupation and two mining leases.

The Cameron Project is located in the southern part of western Ontario, Canada approximately 80 km southeast of Kenora and 80 km northwest of Fort Frances. The nearest
towns  are  Sioux  Narrows  and  Nestor  Falls,  30  km  and  25  km  away  respectively.  The  Cameron  Project  is  on  unsurveyed  crown  lands  accessed  by  sealed  and  all-weather
gravel roads. From Kenora via Highway 17, Hwy 71 and the Cameron Lake road the distance is around 123 km. From Fort Frances via Hwy 11, Hwy 71 and the Cameron
Lake road the distance is 168 km.

55

 
 
 
 
 
 
 
 
 
 
 
 
Underlying royalties which affect the Cameron Deposit are:

● 1.5% NSR payable to Rubicon Minerals Corp. for 47 unpatented claims. We have the option to repurchase 0.75% of the NSR for $750,000;

● 1% NSR payable to Orion Resource Partners for 20 unpatented claims, 4 patented claims, 6 MLOs and 2 mining leases;

● 2%  NSR  payable  to  Mr.  Sherridon  Johnson  and  Mr.  Edward  Antony  Barkauskas  for  one  unpatented  claim.  We  have  the  right  to  repurchase  1%  of  the  NSR  for

$500,000;

● $0.30 per ton on all ore mined payable to the estate of W. Moorhouse and D. Petrunka for one mining lease;

● 3% NSR payable to Lasir Gold Inc. We have the right to reduce the NSR to 1.5% by payment of $1,500,000; and

● 1% NSR payable to Chalice on 133 unpatented mining claims, all of which are not encumbered by pre-existing royalties. We have the right to repurchase 0.5% of the

NSR for $1,000,000.

In order to maintain the title to a mining claim, the recorded holder of the claim is required to undertake approved work expenditure of $400 per single cell mining claim or
$200 per boundary cell mining claim within  two  years  of  the  granting  of  the  claim.  Work  programmes  and  expenditure  commitments  can  be  grouped  across  a  contiguous
series of mining claims. The duration of a mining lease is 21 years from the date of grant. The mining leases within the Cameron Project were initially granted in 1988 and
were subsequently renewed for a further 21 years in July 2009, except one mining lease which was renewed in May 2006.

History

Exploration  in  the  area  commenced  in  the  1940s  and  numerous  companies  have  carried  out  prospecting,  line  cutting,  geological  mapping,  trenching,  soil  and  outcrop
sampling and ground magnetic and electromagnetic geophysical surveys.

On the Cameron Project there have been numerous exploration and drilling programmes. On the Cameron Deposit itself, the first drilling was undertaken in July 1960. Prior
to 2010, there were 836 holes comprising in excess of 90 km of diamond drill core drilled by six companies.

In 1987 at the Cameron Gold Deposit, underground development for an extensive sampling programme was undertaken. Some 65,000 m3  of  material  was  excavated  with
some  bulk  sampling,  diamond  drilling  and  rock  chip  sampling  completed.  The  excavated  material  was  placed  on  surface  at  site  in  three  separate  stockpiles:  one  for
unmineralized access development material, one for “low-grade” mineralized material; and one for “mineralized” material. The unmineralized stockpile has been used from
time to time for access road maintenance. The mineralized material stockpiles have been surveyed and sampled for the purpose of reconciliation against depletion calculations
but no estimate has been prepared that would permit inclusion of the material in a disclosure of resources.

56

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Between 2010 and 2012, 242 surface diamond holes were drilled totalling 36,000 m, the majority on the Cameron Deposit.

Since 2010, the following exploration work has been carried out throughout the Cameron Project consisting of:

● Airborne magnetic gradiometers survey of the project area in 2010.

● 250 km of line cutting over the property

● 142-line km of Pole-Dipole Induced Polarisation surveys (July 2010 to February 2011)

● Orientation geochemical sampling programme of surface pits around the Cameron deposit in late 2011. A total of 19 samples of around 12 kg were collected from

the base of till over an area of about 900 m x 600 m.

● Excavation of 94 pits in 2013 on gold-in-till anomalies.

● Outcrop mapping and prospecting

● Heli-borne magnetics and Versatile Time-domain Electromagnetic (VTEM) over the western portion of the project in 2014. A total of 1457 line km of VTEM was

flown at 200 m spacings.

● Several historical Mineral Resource estimates have been done for the Cameron Deposit.

In May 2014, 15 holes for 2,599.5 m were diamond drilled at the Jupiter, Ajax, Juno and Hermione prospects that are proximal to the Cameron Deposit.

Geological setting, mineralization and deposit type

The  mineralization  at  the  Cameron  Project  is  mainly  hosted  in  mafic  volcanic  rocks  within  a  northwest  trending  shear  zone  (“Cameron  Lake  Shear  Zone” or “CLSZ”)
which dips steeply to the northeast. In the south-eastern part of the deposit where the greatest amount of gold has been delineated, the shear zone forms the contact between
the mafic volcanic rocks and diabase/dolerite rocks of the footwall.

Gold mineralization occurs within quartz breccia veins, associated with intense silica‐sericite‐carbonate‐pyrite alteration in a series of zones that dip moderately to steeply to
the northeast within and adjacent to the shear zone. Gold is associated with disseminated pyrite with high sulphide concentration generally corresponding with higher gold
grade. Visible gold is rare. The mineralization is open at depth and along strike to the northwest with potential to expand the Mineral Resource in these directions.

57

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Cameron Deposit is a greenstone‐hosted gold deposit. While the deposit can generally be considered to be part of the orogenic family of gold deposits, it bears many
characteristics atypical of the largest gold deposits of this style. These features include:

● mineralization dominated by disseminated sulphide replacement and quartz‐sulphide stockwork and quartz breccia veins;

● spatial and temporal association of mineralization with porphyry intrusive bodies that have similar alteration assemblages (taking into account primary lithological

variations);

● relatively minor amounts of auriferous quartz‐carbonate vein material comprising the mineralization, which is likely temporally‐late compared to the disseminated

sulphide replacement and quartz breccia veins;

● high‐grade mineralization is largely deformed and the disseminated sulphide replacement zones that constitute the bulk of the mineralization are commonly foliated;

and

● the alteration assemblage of the mineralization (sericite‐albite‐carbonate‐pyrite) is atypical.

Exploration

Exploration at the Cameron Project commenced in 1960 and has been conducted intermittently until the present day.

Drilling

A  number  of  diamond  drillhole  programmes  have  been  carried  out  across  the  Cameron  Project  area  by  a  number  of  explorers:  Noranda  Exploration  Company  Limited
(“Noranda”)  from  1960  to  1961;  Zahevy  Mines  Limited  and  Noranda  from  1972  to  1974;  Nuinsco  in  1981;  Nuinsco  and  Lockwood  Petroleum  Inc.  from  1983  to  1984;
Nuinsco and Echo Bay Mines Limited from 1985 to 1989; Nuinsco and Deak International Resources Holding Limited in 1989; Cambior Inc. in 1996; Nuinsco from 2003 to
2005; and Coventry Resources Inc. (“Coventry”) from 2010 to 2012. In addition, an RC drilling programme was completed by Nuinsco from 1985 to 1986 to sample the
overlying glacial till and the bottom of hole in bedrock to test for geochemical anomalism associated with gold mineralisation.

From 1960 through to 2012, 981 diamond drillholes were drilled for a total of 120,813 m. An additional 83 RC holes were drilled during the mid-1980s for a total of 862 m.

Underground  exploration  of  the  Cameron  Deposit  commenced  in  October  1986  and  was  undertaken  in  two  phases  until  July  1988  to  verify  the  surface  drilling  results.
Overall, 457 underground diamond drillholes were completed for a total of more than 21,707 m. An additional 55 diamond drillholes were drilled from underground for a
total of 4,887 m between 1989 and 1990.

Sampling, analysis and data verification

Documentation  regarding  historic  field  procedures  applied  by  previous  explorers  at  the  Cameron  Gold  Deposit,  including  details  regarding  sample  collection,  preparation,
transportation and security, and analytical techniques, is poor or non‐existent. Prior to 1988, core was manually split, with half‐core sent for analysis. Post 1988, drill core was
cut using a masonry saw. The inclusion of control samples is assumed and is sometimes referenced in documentation but details regarding this are not documented.

For  the  2010  to  2012  drill  programmes,  drill  core  was  cut  on  site  with  wet  masonry  core  saws  by  geotechnical  personnel  who  are  supervised  by  Coventry  site‐based
geologists.  The  selection  of  intervals  for  cutting  and  the  length  of  these  intervals  was  based  on  lithological,  alteration  or  mineralization  boundaries  as  defined  by  the
supervising geologist with 1 m intervals used in zones of similar lithology. Within mineralization the sampling intervals vary from 0.06 m to 2 m.

Samples were received at the laboratory and checked against accompanying sample dispatch sheets to ensure all samples are delivered. Any discrepancies were noted and
Coventry notified that resolution was required before the samples advanced through the preparation process.

Sample preparation comprised standard laboratory techniques of (i) drying for a minimum of 8 hours, (ii) mill crushing to greater than 70% passing 2 mm, (iii) riffle splitting
(using a Jones Splitter) to approximately 250 gm and (iv) disk pulverising to 85% passing 75 microns. The sample was then split to 30 g for analysis with the remainder
retained as a pulp residue. The coarse remainder was put aside as a bulk residue (reject).

Overweight samples (>2.5 kg) were crushed and split into two samples, treating each as above and recombining after pulverising.

All samples were analysed for gold by accredited and independent Activation Laboratories Ltd. (“ActLabs”) at their Thunder Bay facility using method ‘1A3‐Tbay Au – Fire
Assay Gravimetric’. The 30 g assay sample was combined with fire assay fluxes (borax, soda ash, silica and a lead oxide litharge) and silver added as a collector. The mixture
was placed in a fire clay crucible, preheated at 850°C, intermediate at 950°C and finished at 1060°C over approximately 60 minutes. The crucibles were then removed from
the assay furnace and the molten slag (lighter material) is carefully poured from the crucible into a mould, leaving a lead button at the base of the mould. The lead button is
then placed in a preheated cupel which absorbs the lead when cupelled at 950°C to recover the silver and gold doré bead.

The gold was separated from the silver in the doré bead by parting with nitric acid. The resulting gold flake is annealed using a torch. The gold flake remaining is weighed
gravimetrically on a microbalance. The detection limits are 0.03 ppm Au (lower) and 10,000 ppm Au (upper).

All drill core from the 2010 and 2011 drilling programs is stored in covered steel core racks at the Cameron Project. Every core box is labelled with Dymo tags, recording
hole ID, box number and ‘from’ and ‘to’ depths.

All samples were individually bagged and labelled with unique sample numbers. Corresponding laboratory specific assay tags were included in each sample bag, which were
then sealed with plastic zip‐ties and batched in woven nylon bags. Samples were transported via commercial road transport on a weekly basis during drilling programmes.
The samples were taken to ActLabs in Thunder Bay or to the ActLabs sample preparation facility in Dryden before being transferred to Thunder Bay for analysis.

Drill core was logged in the exploration camp at Cameron Lake. The core was logged for geology, alteration, mineralization, structure and other geological features such as
veining. The core was photographed in wet and dry condition and stored in racks prior to sampling by core cutting. The drill core was marked up with the sample intervals
and the core was cut using a diamond blade saw. Sample tickets were stapled into the wooden core trays and the other half put into the sample bag. The sample number was
also written on the outside of the calico sample bag for identification and sorting purposes. The core is stored in the exploration facility at the Cameron Property. This has
dedicated covered racks for storing drill core, wooden crates for sample residues, and sea containers for sample pulps.

All samples were individually bagged and labelled with unique sample numbers. Corresponding laboratory specific assay tags were included in each sample bag, which were
then sealed with plastic zip‐ties and batched in woven nylon bags. Samples were transported via Gardewine North commercial road transport of Kenora. The samples were
taken to ActLabs in Thunder Bay. Confirmation was sent to Chalice that the security tags were intact, and that the numbers match the sample despatch request.

As part of its QA/QC review, Optiro Pty Ltd. (“Optiro”) was provided a Microsoft access database containing two QA/QC tables. One table comprised standards and blanks
and one table comprised duplicates assay results. Optiro exported these tables into CSV format and imported the QA/QC results into data analysis spread sheets to review the
Cameron QA/QC results.

The underground drilling data collected between 1987 and 1989 was considered critical to the quantity and quality of the 2014 Mineral Resource Estimate, and as no QA/QC
information was available, Coventry undertook a re‐sampling program in order to establish confidence in the assay results. The Coventry re‐sampling programme targeted
mineralization in and around the underground development. Remaining core was quartered either using a core saw or manually (depending on core condition) over the same
sample intervals as currently recorded in the database. The re‐samples were prepared and assayed in exactly the same manner that samples from Coventry’s diamond drilling
programme were processed with sample preparation and analysis carried out at ActLabs in Thunder Bay. This re‐sample programme provided 816 directly comparable assay
results, from a total of 1,904.6 m of drill core. The comparison is between half core (original sample) and quarter core (resample).

Optiro  only  managed  to  identify  101  samples  recorded  in  the  QA/QC  database  to  be  duplicate  samples  and  that  were  submitted  by  Coventry  in  2010  and  2011.  Optiro’s
analysis of the 101 identified quarter core duplicate samples indicates a poor repeatability of grades between paired samples with a correlation coefficient of 0.24. The results
suggest that the duplicate samples are under reporting compared to the original grades at gold grades of less than 1 g/t Au, and over reporting compared to the original grades
at gold grades of greater than 2 g/t Au.

Results  from  the  scatter  plot,  precision  plot  and  relative  difference  plots  highlight  a  moderate  to  poor  precision  and  poor  repeatability  of  duplicates  from  this  resample
programme. In Optiro’s opinion the repeatability and precision of these duplicates does not demonstrate a high level of confidence. However, the small number of samples
does not in Optiro’s opinion provide definitive evidence of issues with the duplicate repeatability. Optiro notes that consideration for differing sample volumes i.e. manually
split  half  core  (versus)  sawn  quarter  core  needs  to  be  taken  into  account  when  reviewing  duplicate  analysis  results.  As  such,  whilst  Optiro  recommends  that  First  Mining
needs to review the performance of the Coventry resample programme further, Optiro considers these results to be adequate for resource estimation.

Optiro has identified 249 blanks submitted by Coventry as part of its resample programmes in 2010 and 2011. Of the 249 blanks submitted four returned grades above 0.03 g
/t Au. This represents a failure rate of less than 2%. Optiro considers these results to be adequate for resource estimation.

60

 
 
 
 
 
 
 
 
 
 
Optiro identified 236 standards submitted by Coventry as part of its resample programmes in 2010 and 2011. Of the 236 standards submitted, 10 different Certified Reference
Material (“CRM”) standards with gold grades ranging from 0.38 g/t to 7.97 g/t Au were used during the Coventry resample programme. A total of 55 gold standards fall
outside three standard deviations which represents a failure rate of approximately 23%. When graphed, it is evident that a large number of the standard failures are potential
sample swaps (i.e. incorrect standard labelling or blanks labelled as a standard). However, due to the close gold grades of a number of standards, it is not possible to determine
with 100% accuracy what the actual standard ID might be.

Optiro does not know whether Coventry resubmitted all failed batches for re-analysis.

Optiro considers that the sample swaps should be rectified in the database so that the QA/QC performance is representative of the performance of the standards. In taking
these into account, Optiro considers that the CRM assay performance is adequate for estimation.

As part of their 2010 to 2012 drilling programmes, Coventry submitted standards, duplicates and blanks as part of their quality control program.

The blank material was obtained from a granite quarry and whilst not certified, was considered by Coventry to be sufficiently homogenous and unmineralized to act as barren
material. Of the 921 blanks submitted eight (8) returned grades above 0.03 g /t Au. This represents a failure rate of less than 2%. These failures were reviewed at the time by
Coventry and were considered to be potential laboratory contamination issues. Optiro considers these results adequate for resource estimation.

Of  the  921  standards  submitted,  six  were  recorded  as  have  grades  of  -99.  Optiro  removed  these  standards  from  the  database  prior  to  any  further  analysis.  A  total  of  12
different CRM standards with gold grades ranging from 0.69 g/t Au to 7.97 g/t Au were used during the Coventry drill programs.

The  provided  database  contained  901  quarter  core  duplicate  samples  collected  by  Coventry  during  the  2010  to  2012  drilling  programmes.  The  duplicates  demonstrate  a
moderate correlation coefficient (0.83) indicating moderate repeatability of grades between paired samples.

The relative precision of a field duplicate dataset is determined by calculating the absolute difference between the two sample’s grades divided by the mean of the sample
pairs.  Good  or  high  precision  suggests  that  the  paired  samples  are  consistent  with  each  other,  both  samples  have  been  well  homogenised  and  that  sample  size  (weight)  is
adequate to be representative of the material collected from the drillhole. Poor or low precision suggests that the samples have been poorly prepared, have a high inherent
nugget,  poor  assaying,  or  are  not  large  enough  to  be  representative.  Of  the  duplicates  submitted  to  ActLabs,  74%  of  assays  were  within  5%  precision,  76%  within  10%
precision, and 78% within 15% precision.

Results from the scatter plot, precision plot, and relative difference plots highlight a moderate to poor precision and moderate to poor repeatability of duplicates from these
phases  of  drilling.  Part  of  this  could  be  due  to  the  use  of  chisel  vs.  saw  splitting,  or  the  use  of  quarter  vs.  half  core  samples,  which  Optiro  does  not  consider  to  be  a  true
representative duplicate sample when dealing with gold mineralisation. As previously stated, taking into account consideration for differing sample volumes (i.e. half core
versus quarter core), Optiro considers these results to be adequate for resource estimation.

In 2014, Chalice undertook a resampling program to provide additional confidence in the underlying drillhole sample assays results used for Mineral Resource estimation.
The samples selected were considered to be spatially representative of the majority of the Cameron Gold Deposit with an emphasis on near surface locations. A total of 492
pulps and 325 coarse rejects were selected from the existing drillholes within the following series:

● Historical holes – resample of pulp samples only

● Coventry 2010 holes – pulps and rejects

● Coventry 2011 holes – pulps and rejects.

The following is an overview of the pulp sampling program taken from the Chalice 2014 Report.

● Selected pulp samples were sent to AGAT Laboratories of Mississauga, Ontario – the Umpire Laboratory

● The samples were not re‐numbered given the sample sequence had never been seen by this laboratory

● The laboratory was requested to place an “A” prefix to the start of the sample number to distinguish these results from the original results.

● Standards and Blanks were included with these samples positioned in the same location sequence as in the original submission; a new Standard was placed in the
position  of  the  original  Standard  (the  original  Standard  sample  being  exhausted  by  the  analytical  process)  whilst  the  Blanks  were  retained  from  the  original
submissions.

The selected samples were renumbered (for disguise) and re‐submitted to ActLabs to preparation and analysis by the method adopted by Coventry and described in previous
reports.

Standards and Blanks were included with these samples positioned in the same location sequence as in the original submission; a new Standard was placed in the position of
the original Standard (the original Standard sample being exhausted by the analytical process) whilst the Blanks were retained from the original submissions.

Results from the pulp duplicate analysis indicates a good repeatability of pulps, while results from the coarse reject analysis illustrate that the average grade of the rejects is
4% lower than the original sample. Optiro was not provided with this data and as such has not been able to replicate these results.

Optiro  considers  the  assay  performance  of  the  pulp  and  reject  samples  to  provide  good  support  for  the  representivity  of  the  analytical  results  and  for  mineral  resource
estimation.

In 2015, Chalice undertook two resampling programs of unsampled intervals within the Cameron Shear Zone. Optiro has based the following analysis of standards, duplicates
and blanks submitted as part of the 2015 resampling programs based on the coding in the provided database.

62

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Of 1,608 blanks submitted during the 2015 resample program, 10 returned grades above 0.03 g/t Au. This represents a failure rate of less than 1%. Optiro considers these
results to be a good measure of the sample preparation process and acceptable for resource estimation.

Of 1,644 standards submitted, 10 were recorded as ‘sample consumed’. Optiro removed these standards from the database prior to any further analysis. A total of 9 different
CRM standards with gold grades ranging from 0.34 g/t Au to 7.97 g/t Au were used during the Chalice resample programmes.

A total of 144 gold standards fell outside of three standard deviations, which represents a failure rate of approximately 9%. The majority (but not all) of the failures appear to
be  sample  swaps  (i.e.  incorrect  standard  labelling  or  blanks  labelled  as  a  standard).  In  this  program,  Chalice  did  not  resubmit  failed  batches  for  re-analysis  but  Optiro
recommends implementation of this protocol for future programs. In addition, Optiro notes the presence of what appears to be cyclic trends in the standard results. Further
investigation into these trends is recommended.

Of  1,629  quarter  core  duplicates  submitted,  one  was  recorded  as  having  a  grade  of  -99.  Optiro  removed  this  sample  from  the  database  prior  to  any  further  analysis.  The
duplicates  demonstrate  a  moderate  correlation  coefficient  (0.79)  indicating  a  moderate  repeatability  of  grades  between  paired  samples.  Optiro  notes  there  are  a  number  of
original samples (43) with barren grade (<0.03 g/t Au) where the duplicate has returned gold grades ranging from 0.1 g/t Au to 2.42 g/t Au. Furthermore, there a number of
duplicate samples (47) of barren grade with an original grade ranging from 0.1 g/t Au to 3.1 g/t Au, suggesting that there are potentially sample swaps.

The relative precision of a field duplicate dataset is determined by calculating the absolute difference between the two sample’s grades divided by the mean of the sample
pairs.  Good  or  high  precision  suggests  that  the  paired  samples  are  consistent  with  each  other,  both  samples  have  been  well  homogenised  and  that  sample  size  (weight)  is
adequate to be representative of the material collected from the drillhole. Poor or low precision suggests that the samples have been poorly prepared, have a high inherent
nugget,  poor  assaying,  or  are  not  large  enough  to  be  representative.  Of  the  duplicates  submitted  to  ActLabs  86%  of  assays  were  within  5%  precision,  87%  within  10%
precision, and 88% within 15% precision.

Results  from  the  scatter  plot,  precision  plot,  and  relative  difference  plots  highlight  a  moderate  precision  and  a  moderate  repeatability  of  duplicates  from  these  resampling
programs.

Based  on  the  good  correlation  coefficient  and  moderate  repeatability  performance  of  the  duplicate  samples  Optiro  considers  the  results  from  the  Chalice  2015  resampling
program to be acceptable for use in a Mineral Resource estimate.

Aside from the pulp resample programme undertaken by Chalice in 2014, Optiro is unaware of any additional umpire duplicate sampling that has taken place at Cameron
Project.

Data verification has been carried out by the author to verify the following elements:

● Deposit location and geology confirmed by site visit to view outcrop exposures, drill core samples and photographs of drillcore;

● Drill collar locations and grid co-ordinates verified by GPS check of randomly selected drillhole co-ordinates;

● Downhole survey deviation compared on an random selection of drillholes;

63

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● Quantum of stated mineralisation supported by independent sampling of mineralization; and

● Assay integrity verified by sample QA/QC analysis, no significant bias identified.

Primary source data (surveys, downhole survey information, assay certificates) checked against database for errors and no material issues identified.

The results of the data validation process have verified the accuracy and integrity of the information provided by Chalice. It is Optiro’s opinion that the Cameron database is
acceptable for the purpose of mineral resource estimation.

Mineral processing and metallurgical testing

A number of preliminary metallurgical studies have been carried out on samples from the Cameron Property from 1985 to the present. Multi-element geochemical assays of
the samples from the drillholes drilled between 2010 and 2012 have indicated that concentrations of deleterious elements (such as sulphur) are not significant.

Metallurgical test work carried out on samples representative of the style of mineralization at the Cameron Gold deposit showed that recoveries of 92% to 93% were returned
from direct cyanidation of samples ground to 75 lm. The results also showed that the recoveries were grind sensitive with maximum recoveries at a P80 grind size in the range
53 to 75 lm. An alternative processing regime of sulphide flotation (mainly pyrite), regrind of flotation concentrate followed by intensive cyanidation of flotation concentrate
and flotation tailings provided gold recoveries marginally higher than direct cyanidation. At a grind size of 75 lm the optimum leach time was approximately 24 hours.

Test  work  completed  in  2013  by  the  Vancouver  branch  of  SGS  used  a  composite  sample  taken  from  17  drillhole  intersections  from  14  separate  drillholes  at  the  Cameron
Project. Comminution tests indicated that:

● rod and ball mill bond work indices are low;

● moderate abrasion index within typical ranges for dolerite-basalt material; and

● JK breakage parameters indicating the material is highly competent.

Gravity recoverable gold is typically around 25% with no improvement in overall recovery after gravity recovery with cyanidation of the gravity tails. Test work carried out in
2014 showed that cyanide in leach processing at a P80 of 75 lm would recover 92.5% of gold with a cyanide usage of 0.2 kg/t and lime usage of 1.2 kg/t. This result was an
improvement on direct cyanidation in terms of reagent usage with a lower recovery (92.5% vs. <95% cyanidation). No processing issues or deleterious elements have been
identified that could have a significant effect on potential mineral extraction in metallurgical test work completed to date.

Mineral resource estimates

The  Mineral  Resource  estimates  for  the  Cameron  Deposit  have  been  generated  from  drillhole  sample  assay  results.  The  interpretations  are  based  on  an  integrated  3D
geological model that defines the relationships of the geological elements at the Cameron Property. The interpreted mineralization wireframes (using a nominal 0.4 g/t Au,
and 0.25 g/t Au cut-off grade for low grade domains) have been used to constrain gold grade estimates. There are eight mineralization domains that are split into two global
areas – ‘northern’ and ‘southern’, with the separation defined by a set of northwest (grid) striking quartz feldspar porphyry (“QFP”) dykes. The southern domain is the most
strongly  mineralized.  The  stronger  mineralization  is  attributed  to  being  dominantly  mafic  hosted  with  an  inflection  point  in  the  Cameron  Lake  Shear  Zone  and  resultant
dilation zone defined by north-south striking hangingwall and footwall QFP dykes.

Block grade estimation parameters have been defined on the basis of geology, drillhole spacing and through geostatistical analysis of the data. Top-cut 1.0 metre composite
samples informed the block grade estimate by ordinary kriging (“OK”) into a panel size of 5 mE by 10 mN and 5 mRL, which is considered appropriate for the distribution of
sample  data  and  the  deposit  type.  Sub-celling  of  the  parent  cells  to  0.625  mE  by  2.5  mN  and  1.25  mRL  was  enabled  to  ensure  good  volumetric  correlation  with  the
mineralization wireframes.

The  Mineral  Resource  estimates  have  been  classified  by  the  geological  understanding,  data  spacing,  block  proximity  to  sample  locations,  underground  development  and
confidence in the block model grade estimate. The Mineral Resource estimate has been reported in accordance with the Standards on Mineral Resources and Reserves of the
Canadian Institute of Mining, Metallurgy and Petroleum 2014 Definition Standards.

The  Mineral  Resources  have  been  reported  using  the  constraints  and  cut-off  grades  specified  in  the  tabulations  below.  The  Mineral  Resource  is  tabulated  in  Table  A  for
Measured and Indicated Mineral Resources and in Table B for Inferred Mineral Resources.

The Measured and Indicated Mineral Resources are defined in the areas of the deposit that have the highest drilling density along with underground development that has
exposed and sampled the deposit on three levels of drift development.

Recent developments

On December 9, 2020, First Mining completed a transaction with Metalore pursuant to which it acquired from Metalore the East Cedartee claims which are located between
the Cameron claim block (which includes the “Cameron Gold Deposit” that hosts the current Mineral Resource on the Cameron property) and the West Cedartree claim block
(which  includes  the  Dubenski  and  Dogpaw  deposits  on  the  Cameron  property).  The  acquisition  of  the  East  Cedartree  claims  consolidates  First  Mining’s  land  holdings  at
Cameron  into  a  single  contiguous  block  and  adds  a  further  3,200  hectares  to  the  49,600  hectares  that  First  Mining  already  holds  in  the  district,  making  a  total  of  52,800
hectares for the entire property. The property area for the Cameron Project is now comprised of 2,002 mining claims, 24 patents, 4 mining leases and 7 licenses of occupation.

Under the transaction, as consideration for the acquisition of the East Cedartree claims, First Mining paid Metalore $3,000,000 in cash, and issued 3,000,000 common shares
of  First  Mining  to  Metalore  (with  such  shares  subject  to  a  statutory  hold  period  of  four  months  plus  one  day  from  closing  of  the  transaction).  The  East  Cedartree  claims
contain  an  existing  Mineral  Resource  estimate  that  was  prepared  in  accordance  with  NI  43-101  and  they  encompass  a  highly  favourable  geological  setting  for  new  gold
discoveries in close proximity to the existing known deposits at First Mining’s Cameron and West Cedartree properties.

Project description, location and access

The Pickle Crow Property is located in northwestern Ontario about 400 km north of Thunder Bay and approximately 11 km east of the town of Pickle Lake. The Pickle Crow
Property is centred at approximately 51º 31’ North latitude and 90º West longitude in NTS map area 52O/11.

The Pickle Crow Property can be reached from the city of Thunder Bay by proceeding westerly on the paved TransCanada Highway (Highway 17) for approximately 245 km
to the town of Ignace and then northward on paved Provincial Highway 599 approximately 290 km to the town of Pickle Lake. From Pickle Lake, access to the Pickle Crow
Property is along a good gravel road that connects to Highway 599 near the village of Central Patricia. The western boundary of the Pickle Crow Property is 6.5 km from the
turn off at Highway 599. The total road distance to the Pickle Crow Property from Thunder Bay is approximately 545 km.

In 2011, the Pickle Crow Property consisted of 98 contiguous patented mining claims covering a surveyed area of 1,583 ha. On August 6, 2014, an additional 8 patented
mining claims were acquired from Frontline Gold Corporation (“Frontline”) which increased the total property area to 1,712 ha. Additional property acquisitions, including
28  claims  from  Metalcorp  Limited  (“Metalcorp”),  increased  the  number  of  unpatented  mining  claims  to  88,  covering  an  area  of  approximately  14,048  ha.  The  original
unpatented ‘legacy’ claims were converted into the new Ontario cell claim system in April 2018 and the current property is made up of 482 mining claims and 106 patented
claims, and now covers an area of approximately 19,000 ha. The claims are located in Connell, McCullagh and Ponsford Townships as well as the Atik Lake, Collinshaw
Lake, Dona Lake, Firstloon Lake and Tarp Lake Areas, in the Patricia Mining Division, northwestern Ontario.

Through our wholly-owned subsidiary, PC Gold, we are party to a 99 year mining lease (the “Mining Lease”) with Teck Resources Limited (“Teck”). The Mining Lease
encompasses the original 98 patented claims of the Pickle Crow property, and it expires on July 31, 2067. The Mining Lease requires payment of $1.00 per year which has
been prepaid in full in advance. Registered ownership of mineral rights and surface rights for the Pickle Crow patented claims is held by Teck as ‘fee simple, absolute’, the
highest level possible.

Our leasehold interest in the original 2008 Pickle Crow Property is additionally subject to two NSRs totalling 1.25% that are payable upon the commencement of commercial
production. We have the option of purchasing these royalties.

The 8 patented claims and a further 5 unpatented claims acquired from Frontline are subject to a 2% NSR royalty in favor of Frontline, one half of which may be purchased
by the Company at any time for $1 million. This NSR is only payable upon the commencement of commercial production.

Certain of the claims acquired from Metalcorp are subject to a 2% NSR royalty in favour of Metalcorp one-half of which may be purchased by the Company at any time for
$2  million.  The  balance  of  the  claims  are  subject  to  a  1%  NSR  royalty  in  favour  of  Metalcorp,  one-half  of  which  may  be  purchased  by  the  Company  at  any  time  for  $1
million, and a 1% NSR royalty in favour of each of two individuals (for an aggregate 2% NSR), one-half of which may be purchased by the Company at any time for $1
million. The consideration for the NSR royalties may be paid in cash or, at the option of the Company, in common shares of the Company, valued by reference to the market
price of the Company's common shares prevailing on the date on which the Company becomes obligated to pay such consideration.

Fourteen  unpatented  claims  belonging  to  the  property  known  as  'Pickle  Lake  #6'  are  subject  to  a  2%  NSR  royalty  payable  to  Cadillac  Ventures  Inc.  (“Cadillac”). The
Company has the option to acquire one-half of the 2% NSR royalty within 3 years of the commencement of commercial production on the Pickle Lake #6 claims by paying to
Cadillac $1 million.

The mining claims in the Pickle Crow Property are subject to annual assessment work requirements to keep them in good standing.

All phases of our exploration activities on the Pickle Crow Property are subject to environmental regulation. These regulations mandate, among other things, the maintenance
of  air  and  water  quality  standards  and  land  reclamation  and  provide  for  restrictions  and  prohibitions  on  spills,  releases  or  emissions  of  various  substances  produced  in
association with certain exploration and mining industry activities and operations. They also set forth limitations on the generation, transportation, storage and disposal of
hazardous waste. A breach of such regulations may result in the imposition of fines and penalties. In addition, certain types of exploration and mining activities require the
submission and approval of environmental impact assessments.

The Pickle Crow Property has, over the course of the past two decades, been subject to several environmental studies which examined, among other things, water quality and
its impact, if any, on the health of aquatic populations in the watershed encompassing it. These preliminary studies indicate that in spite of the history of mining on the Pickle
Crow  Property,  including  a  significant  volume  of  historical  tailings  sitting  in  four  tailings  basins  on  surface  and  extensive  areas  of  flooded  mine  workings,  water  quality
samples generally meet provincial water quality standards. This appears to be due in part to the generally low sulphide content and natural buffering effect of the carbonate
minerals found in the vein ore historically mined.

History

The  Pickle  Crow  deposit  was  originally  discovered  in  the  early  1930s  and  commercial  production  at  the  mine  began  in  1935.  The  Pickle  Crow  mine  operated  until  1966
during which time it produced 1,446,214 troy ounces of gold and 168,757 troy ounces of silver from 3,070,475 tons of ore milled (at an average grade of 0.47 oz./t or 16.14
g/t). The Pickle Crow Property sat dormant from 1966 to the late 1970s.

In 1979, a VLF-EM (very low frequency-electromagnetic) geophysical survey of the Pickle Crow Property was performed and 47 surface diamond drillholes for 7,356 m
were drilled. The only known soil geochemical survey done on the Pickle Crow Property was completed in 1983. The samples were collected along the same cut grid lines as
used for the VLF-EM survey. Soil values ranged from 10 to 12,000 ppb, with the high values attributed to the mine tailings and thought to be cultural anomalies.

68

 
 
 
 
 
 
 
 
 
 
 
Between 1985 and 1987, the most extensive exploration program on the Pickle Crow Property since its closure and up to that time was completed. The program consisted of
line-cutting, magnetometer and induced polarization geophysical surveying, geological mapping, surface trenching, diamond drilling and environmental baseline studies. In
total, 286 surface diamond drillholes drilled for 46,189 m and 79 underground diamond drillholes for 9,341 m which were completed between 1985 and 1988. Following
completion of the program, all shafts, ventilation raises and other surface openings were capped with concrete in 1989 after an estimated $9.2 million was spent on the Pickle
Crow Property. Two historic (non-NI 43-101 compliant) resource estimates were commissioned, one in April of 1988 and a second in December of 1988.

A total of four surface diamond drillholes for 2,287 m were drilled in the fall of 1998. An additional 18 surface diamond drillholes were completed in 1999 for 2,173.5 m.

Between 1999 and 2001, two bulk samples were taken from the No. 5 Vein and No. 1 Vein crown pillars respectively.

In  2002,  the  building  of  a  225  t/d  extreme  gravity  mill  was  commenced  on  the  site,  a  partially  complete  production  closure  plan  was  submitted  to  the  then  MNDM  and
construction of a tailings management facility within the historic Pickle Crow tailings area began. Stockpiling of material mined from the historic No. 1 Vein shaft and crown
pillar area in the summer of 2002 also commenced.

On  May  13,  2008,  PC  Gold  acquired  its  interests  in  the  Pickle  Crow  Property.  It  then  launched  an  exploration  program  in  conjunction  with  the  staking  of  surrounding
unpatented claims which now define the boundaries of the current Pickle Crow Property.

Geological setting, mineralization and deposit types

The Pickle Crow Property lies within the Pickle Lake greenstone belt, part of the Uchi Subprovince, which is within the Superior Province of the Canadian Shield. The Pickle
Lake  greenstone  belt  comprises  an  approximately  70  km  long  by  25  km  wide  area  of  supracrustal  rocks  and  internal  granitoid  plutons  surrounded  by  large  granitoid
batholiths.

The supracrustal rocks have been deformed and metamorphosed to greenschist facies with amphibolite facies occurring in the thermal aureoles of younger plutonic bodies.
The Pickle Lake greenstone belt is subdivided into four tectono-stratigraphic assemblages including:

● The Pickle Crow assemblage.

● The Kaminiskag assemblage (not present on the Pickle Crow Property).

● Unnamed Temiskaming-like assemblage.

● The Confederation assemblage.

On the Pickle Crow Property, the Pickle Crow assemblage is dominated by tholeiitic basalts with intercalated sediments (primarily banded iron-formation, sometimes referred
to  as  BIF),  and  rare  calc-alkaline  volcanic  and  volcaniclastic  units.  The  assemblage  occupies  the  northwestern  part  of  the  greenstone  belt  and  is  interpreted  to  be
unconformably overlain by the Confederation assemblage.

69

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Gold  mineralization  on  the  Pickle  Crow  Property  is  orogenic  in  nature  and  occurs  in  complexly  folded  and  sheared,  mainly  tholeiitic,  volcanic  rocks  of  the  Pickle  Crow
assemblage  near  its  contact  with  calc-alkaline  volcanic/volcaniclastic  rocks  of  the  Confederation  assemblage.  Host  rocks  for  the  mineralization  include  tholeiitic  lavas,
banded iron formation, intermediate volcanic/volcaniclastic rocks and quartz feldspar porphyry. Gold occurrences on the Pickle Crow Property are associated with four styles
of mineralization:

● Narrow, high-grade gold-scheelite-bearing quartz veins, which were the main source of gold produced at the Pickle Crow mine from 1935 to 1966.

● Iron formation-hosted gold mineralization adjacent to vein structures. The iron formation contains stringers and discontinuous lenses of quartz and the iron-bearing
minerals  have  been  replaced  by  sulphides.  Both  quartz  and  sulphides  are  gold-  mineralized.  Only  a  limited  amount  of  this  type  of  material  was  processed  at  the
Pickle Crow mine. However, iron formation-hosted gold was the main ore type at the adjacent Central Patricia mine to the southwest.

● Shear zone-hosted gold mineralization consisting of complex wide zones of intense shearing and alteration which are intimately associated with the intrusion of the

Albany porphyry and characterized by disseminated pyrite, discontinuous quartz veining and sulphidation of interflow iron formation.

● Arsenopyrite-associated gold mineralization which typically occurs as disseminated to semi-massive arsenopyrite and quartz-arsenopyrite stockworks hosted by iron
formation but can be also found, to a lesser extent, in shear zones and/or quartz veins in volcanic rocks. Similar arsenopyrite-rich iron formation-hosted gold was the
main ore type at the adjacent Central Patricia mine.

We consider the gold occurrences in the Pickle Lake mining camp to be classical examples of deposits grouped under the descriptive model of Archean low-sulphide gold-
quartz  veins.  This  deposit  type  is  also  known  as  shear-  zone-hosted  gold,  Archean  quartz-carbonate  vein  gold  deposits,  Archean  lode  gold,  Archean  mesothermal  gold  or
orogenic gold.

Exploration

In 2007, sourcing and compilation of available historical data was started.

In October 2007, a total of nine samples were collected from the Pickle Crow Property. Two types of samples were obtained on a spontaneous and random basis: eight field
duplicate split core samples from a series of drillholes that are stored at two locations on the Pickle Crow Property and one composite chip channel sample taken from the
outcropping one vein in its bulk sample pit.

Starting in the spring of 2008 PC Gold commenced an extensive exploration program consisting of locating historical drill collars with a differential GPS; surveying historical
shafts; reconnaissance geological mapping and relocating historical trenches; limited channel sampling and mapping of historical trenches and diamond drilling of 33 holes
with up to 2 rigs totalling 8,638 m in the core mine trend to confirm historical holes. This program confirmed the results of historical drillholes and provided confidence in the
digital database.

70

 
 
 
 
 
 
 
 
 
 
 
 
 
Field exploration was renewed in the spring of 2009 with a focus continuing on the core mine trend. This exploration program consisted of diamond drilling of 34 holes with
up  to  3  rigs  totalling  14,308  m;  shallow  drilling  targeting;  U-Pb  age  dating  of  detrital  zircons  from  two  samples;  line  cutting  (114.9  km)  on  the  core  mine  and  Cohen-
MacArthur trends; a Titan IP (71.45 line-km, 80.25 km with current extensions) and ground magnetometer survey (110 line-km); and prospecting with a focus on the Cohen-
MacArthur  trend.  The  most  significant  results  of  the  2009  program  were  the  discovery  of  Conduit  Zone  1,  the  discovery  of  Pickle  Crow  type  high-grade  veins  hosted  in
intermediate  volcanic  rocks  and  gabbro  of  the  Confederation  assemblage  (Confederation  veins),  possibly  representing  surface  expression  of  a  vein,  the  identification  of
Temiskaming-like sediments in the core mine trend, and the identification of the Cohen-MacArthur trend by geophysics.

In 2010, exploration continued with the focus remaining on the core mine trend but expanding to include the Cohen-MacArthur trend. The exploration program consisted of
diamond  drilling  of  106  holes  with  up  to  4  rigs  totalling  35,545  m,  including  helicopter  supported  drilling;  and  trenching  program  consisting  of  9  trenches  totalling
approximately 32,000 m2 including 1,707 channel samples. The most significant results of the 2010 program were the discovery of the no. 19 vein, the Kawinogans Zone and
the Central Pat East Zone and the extension of the No. 1 Vein 700 m below the historical workings. The No. 20 and 21 Veins were also discovered.

The exploration program continued in Q1 2011 with drill testing of the core mine but with a focus on regional targets along the Cohen-MacArthur trend. The exploration
program consisted of diamond drilling of 11 holes with up to 3 rigs, totalling 4,476 m; 881.4 line-km of 50-m spaced helicopter borne AeroTEM and magnetometer surveys;
and  completion  of  baseline  water  sampling  and  sampling  of  stockpiled  high  and  low  grade  ore  for  finalizing  the  closure  plan.  Significant  results  of  the  2011  exploration
program include the expansion of the Central Pat East Zone as a possible near surface, bulk tonnage target and the continued expansion of the No. 19 Vein.

On April  18,  2011,  PC  Gold  announced  a  1.26  million  ounce  NI  43-101-compliant  Inferred  Mineral  Resource,  audited  by  Micon  International  Limited  (“Micon”), which
triggered the preparation of the Pickle Crow Technical Report.

Drilling

Since  acquiring  the  Pickle  Crow  Property  in  early  May  2008,  PC  Gold  has  conducted  an  aggressive  diamond  drill  program  designed  to  confirm  and  expand  the  historic
resources and make new discoveries. The most prominent of these new discoveries was the No. 19 Vein with 15.95 g/t Au over 0.70 m. Follow-up intercepts of the zone
included  43.28  g/t  Au  over  13.13  m  and  are  considered  by  PC  Gold  to  represent  the  most  significant  discovery  since  the  closure  of  the  mine  in  1966.  Other  discoveries
include the Conduit Zones in the Albany Shaft area and the Central Pat East Zone along the Cohen-MacArthur trend.

A total of 184 holes totalling 62,968 m were drilled on the Pickle Crow Property between June 2008 and March 12, 2011. Drilling was completed in three phases as described
above.

All holes were drilled with NQ-sized core (47.6 mm) with the exception of 9 BQ Thin Wall holes (40.7 mm) drilled.

The bulk of the PC Gold holes were drilled in the core mine trend with the second largest concentration along the Cohen-MacArthur trend. Several new mineralized zones
were intersected. Other newly discovered zones include the No. 20 and 21 Veins, the Confederation Veins, and the Kawinogans Zone. Significant extensions to known zones
include extending the No. 1 Vein at Shaft 1 to 1,500 m depth and the intersection of abundant quartz veining beneath the workings of Shaft 3 which is interpreted to be the
extension of the No. 6 and 7 Veins.

The drilling program has extended several known zones and outlined new discoveries. These include high grade, narrow vein targets and more disseminated bulk tonnage
targets which may be amenable to open pit or underground bulk mining.

71

 
 
 
 
 
 
 
 
 
 
 
 
 
Since 2011, 173 new holes have been drilled totalling 35,840.4 m. The 2011 to 2014 drilling concentrated mainly on the core mine trend and postulated eastward extensions
of the Central Patricia trend. The principal targets on the core mine trend were the No. 1 and No. 5 Veins and the BIF.

First  Mining  completed  small  diamond  drill  programs  in  2016  and  2017  to  meet  the  annual  assessment  work  requirements  for  the  Pickle  Crow  Property.  The  fall  2016
program was centred on selected targets in the core mine trend from the No.1 Shaft to the Crowshore shaft, and consisted of 9 holes totalling 1,318 m. The winter 2017 drill
program was designed to test the potential westward extension of the core mine trend and consisted of 6 holes, totalling 1,254 m.

Sampling, analysis and data verification

Two types of sample collected by PC Gold during exploration of the Pickle Crow Property were used in the preparation of the Mineral Resource estimate presented in the
Pickle Crow Technical Report, channel samples from trenches and diamond drill core. Sampling procedures remained the same after the previous 2011 Mineral Resource
report.

Channel  Samples  –  Collection  of  the  trench  channel  samples  was  completed  after  the  trenches  were  excavated,  washed  and  mapped.  Channel  sampling  was  performed
utilizing a Stihl ‘quick-cut’ rock saw. Two continuous parallel cuts were sawn approximately 5 cm apart and approximately 5 cm deep, with the rock in between then chipped
out using a chisel. Sample lengths varied between 0.3 and 2.0 m averaging 0.90 m. Each sample was placed in a thick plastic bag with the sample number clearly written on
the outside of the bag with permanent marker and with one portion of a three-part sampling ticket placed inside. Each sample was sealed with a cable strap. The location of
the samples was noted in the sample book and on the trench map. Aluminum tags with etched sample numbers were hammered into the cross cuts, using cement nails, at the
beginning  of  each  sample  interval  for  a  permanent  record  on  the  trench.  Once  collected,  the  samples  were  bagged  and  shipped  as  per  the  sample  shipment  procedures
described below, with the exception that all channel samples were shipped to AGAT Laboratories Ltd. (“AGAT”) of Mississauga, Ontario.

Diamond  Core  Logging  and  Sampling  –  NQ  diameter  (47.6  mm)  drill  core  was  logged,  then  sawn  in  half  using  diamond  bladed  saws  at  the  secure  logging/core-cutting
buildings  onsite,  under  the  overall  supervision  of  the  logging  geologists.  The  core  was  sawn  in  half  following  a  sample  cutting  line  determined  by  the  geologists  during
logging. After cutting, one half of the core was bagged, labelled and sealed with a zip tie or staples after one part of the three-part sample tag was placed inside. The second
part of the sample tag was stapled into the core box at the beginning of each sample. The third part of the tag was kept in the sample tag book as a permanent record. The
remaining half core was placed in core boxes to serve as a permanent record and stored in a secure onsite facility. All samples were shipped from the site in a locked wooden
crate with security tags. The samples were transported via Manitoulin Transport to laboratory preparation facilities in Thunder Bay, Ontario for crushing, pulverization and
pulp preparation. In 2008, samples were shipped to ALS Chemex’s (“ALS”) facility in Thunder Bay. In 2009 and 2010, samples were sent to Accurassay in Thunder Bay.

Once  the  core/channel  samples  were  cut,  bagged  and  sealed  with  zip  ties  or  staples,  ten  samples  were  put  into  a  larger  rice  bag,  which  was  then  sealed  with  a  secure,
numbered security tag. The security tag numbers were recorded along with the corresponding samples within the bag, and then shipped in the locked wooden crates to the
laboratory. Once they arrived at the laboratory, the security tags and corresponding samples were recorded again by the laboratory and emailed back to the PC Gold field site
for confirmation. Prior to shipment the sample bags were stored in a locked building onsite. The site was always occupied during exploration. No samples were left at the
project site during field breaks.

A  total  of  5,797  drill  samples,  which  include  QA/QC  samples  (i.e.  duplicates,  standards  and  blanks)  were  submitted  to  ALS  in  2008  for  analysis.  A  total  of  42,392  drill
samples,  including  QA/QC  samples,  were  submitted  to  Accurassay  in  2009  and  2010  for  analysis.  A  total  of  1,577  channel  samples,  including  QA/QC  samples,  were
submitted to AGAT in 2010 for analysis.

72

 
 
 
 
 
 
 
 
 
 
 
For the analysis of Pickle Crow Property drill core samples, ALS was chosen as the primary laboratory in 2008. Accurassay was chosen as the primary laboratory for drill
core samples in 2009 and going forward.

In 2008, samples were crushed and prepared at ALS’ facilities in Thunder Bay, Ontario and sample pulps were shipped to its North Vancouver, British Columbia laboratory
for analysis. ALS’ facilities in Thunder Bay are certified to ISO 9001. The laboratory in North Vancouver is accredited to ISO 17025 for gold fire assay by atomic absorption
and gravimetric finish as well as four-acid multi-element analysis by ICP and MS. In 2009 and 2010, samples were crushed, prepared and analyzed at the Accurassay facility
in Thunder Bay, Ontario. Accurassay is accredited to ISO 17025 for gold by fire assay with atomic absorption finish. The trench channel samples were assayed at AGAT in
Mississauga, Ontario. AGAT is accredited to ISO 17025.

All samples sent to ALS for analysis were prepared using a jaw crusher, which was cleaned with compressed air between samples, resulting in 70% of the sample passing
through a 10 mesh screen. A 1,000 g split of the crushed sample was then pulverized to 85% passing a 200 mesh screen. All samples sent to Accurassay for analyses were
prepared using a jaw crusher, which was cleaned with a silica abrasive between samples, resulting in 90% of the sample passing through an 8 mesh screen. A split of the
crushed sample weighing 1,000 g was then pulverized to 90% passing a 150 mesh screen. AGAT’s sample preparation procedures include crushing to 75% passing 2 mm and
pulverizing to 85% passing 75 µm.

For all three laboratories, the prepared sample pulps were analyzed for gold by fire assay using 50-g sample charge with AAS finish. If the returned assay result was equal to
or greater than 5 g/t then the sample was reassayed by fire assay with gravimetric finish. All samples greater than 10 g/t, and any samples suspected of nugget gold (quartz
veins) were additionally sent for pulp metallics analysis using the remainder of the pulp (~950 g of sample).

PC Gold has completed bulk density measurements on 2,602 samples of mineralized and unmineralized diamond drill core, and select grab samples from “ore” stockpiles
onsite from the Pickle Crow mine. Of these, 1,918 measurements were used in the calculation of average specific gravity for the Pickle Crow Property. During a review of the
data, 684 measurements were discarded due to laboratory errors that produced unrealistic specific gravity values.

Diamond drillhole data and trench data were stored in Excel spreadsheets. These can easily be imported into Microsoft Access database software and used in many resource
estimation/mine planning software packages. We also use Gemcom software to evaluate drill results and has the finalized data stored in Microsoft Access. Excel is used to
manage the data and QA/QC program.

The Pickle Crow Project QA/QC program includes the use of crush duplicates, ¼-split drill core (field duplicates), the insertion of certified reference materials including low,
medium and high-grade standards and coarse blanks. This is accomplished by inserting the QA/QC samples sequentially in the drill core sample numbering system. One set
of the four QA/QC types were inserted every 30 samples, consisting of 1 crush duplicate, 1 quarter-split field duplicate, 1 standard (alternating between a low, medium and
high standard), and 1 blank. This resulted in approximately every seventh sample being a QA/QC sample.

Sample  assay  results  are  evaluated  through  control  charts,  log  sheets,  sample  logbook  and  signed  assay  certificates  to  determine  the  nature  of  any  anomaly  or  failure.
Identified failures are re-assayed by the laboratory at which the failure occurred until a cause of the failure and correct analysis is obtained. Check assaying is also conducted
on approximately 1 in every 20 samples. The pulps are re-numbered with new, sequentially-inserted QA/QC samples and sent to a second ISO certified laboratory (ActLabs
of Ancaster, Ontario).

73

 
 
 
 
 
 
 
 
 
 
 
Approximately  1  out  of  every  20  samples  for  the  Pickle  Crow  Project  was  submitted  to  a  second  laboratory,  ActLabs,  an  ISO  17025  certified  laboratory  with  a  sample
preparation and analytical facility in Ancaster, Ontario. The assaying protocol used is similar to ALS and Accurassay’s using fire assaying with a 50-g charge and AAS finish.
Samples above 3 g/t Au are re-assayed using a gravimetric finish, and above 10 g/t by pulp metallic methods. A total of 2,117 check samples were sent to Actlabs. Check
assays  generally  matched  the  value  obtained  by  the  original  laboratory  and  the  overall  variation  between  laboratories  was  well  within  the  natural  variation  of  the  sample
material as indicated by the field and crush duplicates.

During the October 2011 site visit, Micon did not complete any check sampling. Micon did examine surface exposures and stockpiles of mineralization from the No. 1 Vein
and No. 5 Vein. Visible gold was noted in the samples on the No. 1 Vein stockpile.

The final database was sent to Micon in early March 2011 for validation. Micon performed a thorough validation of the database and specifically performed a cross-check
validation of the assay table against assay results received directly from the laboratories in electronic form. The cross-check validation of the assay table described above was
possible only for the newer PC Gold-generated data which contained laboratory sample identification numbers.

Several minor problems were found and corrected, most of them located outside of the modelled zones. The problems were related to the fact that the majority of the database
was collected from historical data digitized from old paper logs.

It is Micon’s opinion that the Company and PC Gold have run an industry standard QA/QC program for the drillhole database and insertion of control samples into the stream
of core and channel samples for the Pickle Crow Project exploration program.

While certain minor discrepancies in survey data of old workings have been noted it has been determined they will only affect the precise location in space of the workings
and  are  not  likely  to  materially  affect  the  estimate  of  remaining  volumes  of  mineralization.  As  such  they  are  suitable  for  use  in  an  Inferred  Mineral  Resource  estimate.
Determination of Measured and Indicated Mineral Resources or Mineral Reserves in the future will require resolution of these minor discrepancies, likely by dewatering and
re-accessing the workings.

The historic drill data have been shown to be acceptable for use in a mineral resource estimate with appropriate application of assay top cuts as discussed above.

Mineral processing and metallurgical testing

The historic ore produced at the Pickle Crow mine presented no major milling problems.

Pickle Crow Mill, 1935-1966: The long since removed process plant for the Pickle Crow mine ran from 1935 to 1966. The 400 ton/day (360 t/d) mill recovered gold by a
combination of gravity/amalgamation and cyanidation. Overall gold recovery averaged slightly over 98%. When the mine closed in 1966 efficiency in the gravity section had
been improved to achieve as much as 60% of the total recovery.

74

 
 
 
 
 
 
 
 
 
 
 
 
 
1999-2002: In October 1999, prior to mining the first of two bulk samples, grab samples were collected from the surface exposures of the No. 5 Vein. These samples were
sent to ORTECH Inc. of Mississauga, Ontario for bottle roll leach tests. The bottle roll tests were conducted on minus 8 material assaying 53.2 g/t Au, and minus 100 mesh
material assaying 40.04 g/t Au. After 48 hours, 53.5% and 95.4% recoveries were achieved for the minus 8 and minus 100 mesh fractions respectively.

No. 5 Vein Crown Pillar Bulk Sample: In December 1999, a bulk sample from the No. 5 Vein crown pillar was mined and sampled, estimated to contain 9,500 tons (8,600
tonnes) averaging 0.38 oz./t Au (13.02 g/t Au) assuming a 3.0 ft. (0.91 metre) minimum mining width; cut to 1 oz./t and 25% diluted. The average grade of the resource block
was determined using a weighted average 9 drillhole and channel samples located inside the block. The bulk sample was carefully mined from a small open pit, with vein
material comprising an estimated 95% and wall rock dilution only 5% of the sample. The bulk sample was shipped to St. Andrews Goldfields Ltd. 1,300 t/day CIP (carbon-
in-pulp)  gold  process  plant  located  at  Stock  Township  near  Timmins,  Ontario  for  custom  milling.  The  shipment  was  processed  on  December  21,  1999.  The  commercial
settlement was agreed upon at a recovered grade of 16.72 g/t Au (0.49 oz./t Au).

No. 1 Vein Crown Pillar Bulk Sample: A second phase of bulk sampling was initiated in 2000. 4,427 tonnes of material (over 90% from the No. 1 Vein) were trucked to the
Golden  Giant  mill  near  Hemlo,  Ontario  for  custom  milling.  The  custom  milling  flowsheet  included  secondary  crushing,  grinding,  gravity  concentration,  leaching,  CIP,
stripping, electrowinning and refining. The shipment was processed between December 4 and 10, 2000. The commercial settlement was agreed upon at a recovered grade of
16.72 g/t Au (0.49 oz./t Au). Prior to accepting the Pickle Crow Property bulk sample, laboratory metallurgical tests were completed to determine if the material could be
treated  at  the  mill  and  if  the  tailings  produced  would  have  a  negative  environmental  impact  on  the  tailings  basin.  No  environmental  problems  were  noted.  The  test  work
indicated that about 40% of the gold was recoverable with a single pass gravity Knelson concentrator. The remaining gold could be easily leached with cyanidation with an
optimum grind of 75% passing 200 mesh. Test work indicated that higher grinds could result in lower gold recoveries. Leach retention times of greater than 48 hours might be
required. An overall recovery of 98.4% was achieved in the tests.

No. 1 Vein Crown Pillar Bench Scale GRG & Leaching Test work: A set of five approximately 20 kg samples from the No. 1 Vein Crown Pillar bulk sample were submitted to
the Knelson Research and Testing Centre (“KRTC”) in Langley, British Columbia for gravity-recoverable-gold (“GRG”) and leaching testwork. These samples were sent
from the Golden Giant mine. The samples were received at the KRTC facility on July 3, 2001. The samples were weighed and logged prior to any processing. The primary
objective of this test work was to quantify the gravity recoverable gold content of the ore using a standard test. The secondary objectives were to determine the average head
grade of the sample and to perform cyanide leach tests on sub-samples of the final tails. A KC-MD3 laboratory scale Knelson Concentrator was utilized for the GRG test
work.

The procedure used for the KC-MD3 stage test was as follows:

● The samples were sorted by time and date into lots of approximately 20 kg.

● Each sample was screened at 10 mesh prior to the first pass through the KC-MD3 in order to prevent plugging. The oversize was saved and subsequently added into

the first grind.

● The ~20 kg test samples were processed through a 3” Laboratory Knelson Concentrator at a fluidization water flow rate of ~3.5 litres/min and at 60Gs.

● During the test, sub-samples of the tailings stream were collected for assays.

75

 
 
 
 
 
 
 
 
 
 
 
 
● At the end of the concentration stage, the concentrate was washed from the inner cone of the KC-MD3.

● The concentrate was panned to produce a pan concentrate and pan tailings (middlings) sample.

● The concentrate and tailings samples were labelled, dried, weighed and sent to an independent local lab for assaying.

● The tailings were re-ground two more times and steps 3 to 6 were repeated after each grind.

● During the final stage, an additional 2 kg sample of the tails was sub-sampled, dried and sent for cyanide leach test work.

● The remaining tails samples are being stored at the test facility.

This testing scheme is based on the philosophy that progressive size reduction allows the determination of gold liberated at finer grinds without over-grinding and smearing
coarse gold present in the initial sample.

Results indicate that the No. 1 Vein crown pillar samples have a very high gravity-recoverable gold content of 91.2% with a back-calculated head grade of 20.0 g/t Au. The
overall  mass  pull  to  the  concentrate  was  1.4%.  The  results  indicate  that  the  gold  is  fairly  liberated  in  this  particular  material  and  is  readily  recoverable.  Visible  gold  was
observed in all final concentrate samples.

Cyanide leaching was performed on sub-samples of the final GRG test tails.

The gold recoveries from leaching ranged from 93.5% to 95.4%. When the leach recoveries are combined with the gravity stage recoveries, the overall recoveries exceed 99%
for all samples. The final tailings assays were very low ranging from 0.09 to 0.11 g/t Au. Based on the encouraging bench scale GRG test results on the No. 1 Vein crown
pillar it was decided to commission the construction of a 225 tonne per day (~250 t/d) extreme gravity gold mill at Pickle Crow.

The concept of “extreme gravity” is a series of innovations that have resulted in a reintroduction of gravity recovery systems into the milling operations of most gold mines.
Traditionally, most gold milling circuits are designed around flotation and cyanidation requirements, with the gravity circuit being fit in where possible. Extreme gravity takes
the approach of optimizing the circuit in order to maximize recovery by gravity. In some cases gravity systems can achieve high enough recoveries to eliminate the need for
chemical systems such as cyanidation and flotation.

The  benefits  of  extreme  gravity  include  relatively  low  capital  costs  compared  to  conventional  gold  mills,  reduced  permitting,  short  project  lead  time,  and  much  reduced
environmental issues with no use of cyanide or other chemicals. In addition, small plants can be modular and easily moved between locations.

Pickle  Crow  Tailings  Bench  Scale  GRG  &  Leaching  Test  work:  In  September  2001,  a  composite  sample  from  Tailings  Area  1  was  submitted  to  Lakefield  Research  of
Lakefield, Ontario for cyanide leach test work. The sample, a blend of oxidized (10%) and unoxidized (90%) tailings, was leached for 48 hours. In May-June, 2002, a set of
two approximately 8 kg composite samples from Tailings Area 3 were subjected to ‘gravity recoverable gold’ and cyanide leach test work. Composite A was made up of
auger drillhole sample material assaying >0.3 g/t Au and composite B material assaying <0.3 g/t Au. The GRG test work was performed by the Knelson Research and Testing
Centre in Langley, British Columbia and leach tests were conducted at Accurassay of Thunder Bay, Ontario.

Post 2011 Metallurgical Testing

After the completion of the previous 2011 Mineral Resource estimate, PC Gold completed some additional metallurgical testwork.

2012 Banded Iron Formation (BIF) Samples: Four samples ranging from approximately 40 to 100 kg were sent to SGS Lakefield in two batches in 2012. Samples BIF-1 and
BIF-2 were selected from Cantera’s low grade BIF stockpile, care was taken to select samples with minimal weathering. Samples BIF-3 and BIF-4 were collected from PC
Gold drill core from the No. 5 BIF zone. Sample BIF-3 represents the deepest intercept (approximately 1,100 m) to date on the No. 5 BIF zone. Samples were ground in a rod
mill  and  passed  through  a  Knelson  MD-3  concentrator,  and  the  concentrate  was  then  further  treated  by  a  Mozley  table.  Gravity  tails  then  underwent  bottle  roll  test
cyanidation.

Historically, the BIF-hosted mineralization was typically below the cut-off grade (8.57 g/t) of the historic Pickle Crow mine and thus was not mined in any significant
quantities. As such, is there is no documented metallurgical history. Anecdotal evidence from past workers at Pickle Crow suggest that their mill setup did not result in great
recoveries when processing BIF, however, what constitutes bad recovery in a mine where >98% recoveries were the norm is unclear.

Cantera performed one bench scale gravity test on the BIF which resulted in 87.6% recovery. PC Gold’s results do not support this; it could be that Cantera’s sample had a
high  proportion  of  stringer  high-grade  vein  material  in  it.  PC  Gold’s  results  (Table  13.9)  indicate  the  BIF  has  poor  gravity  recoveries  (average  of  28.8%  at  75  microns),
however, it has acceptable gravity plus cyanide recoveries (average 89.9%).

2013  High-Grade  Vein  Samples:  In  January  2013,  PC  Gold  submitted  two  samples,  each  comprising  approximately100  kg  from  Cantera’s  high-grade  stockpile  from  the
crown pillar of the No. 1 Vein, to SGS Lakefield (SGS), in Lakefield, Ontario. These consisted of a high-grade sample (HG) with a moderate amount of visible gold, and a
low-grade sample (LG) with no visible gold, the samples were of vein material only and care was taken to select unweathered material.

The results of SGS indicated that the HG sample returned a head grade of 198 g/t and the LG sample 33.4 g/t. The test was carried out by milling the samples using a rod mill
to three different grind sizes, approximately160, 90, and 60 microns and then passing them through a Knelson concentrator with a Mozley table finish.

PC Gold’s test work is on the low end of Cantera’s Knelson test work, PC Gold’s % recoveries were achieved with a single grind and pass through the Knelson, whereas
Cantera’s involved 3 passes through the Knelson and 2 stages of grinding.

Mineral resource estimates

The Pickle Crow Project resource estimate is divided into three distinct areas within the core mine trend: the Shaft 1 area, the Shaft 3 area and the Albany Shaft area. These
areas comprise three mineralization styles, high-grade narrow veins, iron formation-hosted and alteration-shear zone-hosted gold mineralization.

The Mineral Resources were estimated using kriging, where variograms could be modelled, and inverse distance cubed interpolation elsewhere. Based on the use of historic
drilling and the somewhat imprecise modelling of the underground workings, the resources have been classified as Inferred Mineral Resources under the CIM guidelines. The
resources were reported using a Whittle-optimized pit shell or at underground cut-off grades.

In 2016, Micon updated the Mineral Resource models for the No. 1 and No. 5 Veins and the BIF using new drilling completed since 2011. The No. 19 Vein block model was
adjusted  so  as  to  constrain  interpretation  to  the  Pickle  Crow  porphyry  and  then  re-estimated.  The  No.  2  Vein  block  model  had  the  crown  pillar  removed  when  it  was
discovered  to  have  been  mined  out.  The  newly  discovered  Vein  22/23  structure  was  modelled  by  Fladgate  and  that  model  was  reviewed.  Otherwise,  the  remaining  vein
models are unchanged from 2011 but have been reported using different cut-off grades.

The resulting estimate of Inferred Mineral Resources for the Pickle Crow Project is presented in Table A below.

2014 CIM Definition Standards were followed for Mineral Resources.

Notes:
1. The Mineral Resource estimate is entirely classified as Inferred Mineral Resources.
2.
3. The Mineral Resource has been estimated using a gold price of US$1,300/oz.
4. High-grade assays have been capped. Each domain was capped with respect to their unique geology and statistics.
5. The  Mineral  Resource  was  estimated  using  a  block  model.  Three  dimensional  wireframes  were  generated  using  geological  information.  A  combination  of
kriging and inverse distance estimation methods were used to interpolate grades into blocks of varying dimensions depending on geology and spatial distribution
of sampling.

6. Mineral  Resources  that  are  not  Mineral  Reserves  do  not  have  demonstrated  economic  viability.  There  is  currently  insufficient  exploration  to  define  these

Inferred Mineral Resources as an Indicated or Measured Mineral Resource.

7. Mineral Resources have been adjusted for mined out areas. Small rib and sill pillars around old stopes have not been considered or reported.
8. Numbers may not add due to rounding.

Considering that a combination of current drilling, historic drilling and underground chip samples were used in the resource estimation, no particular common sample grid
exists.  There  also  exists  a  known  minor  error  in  terms  of  sample  location  and  the  accuracy  of  the  digitized  underground  workings.  However,  even  though  these  known
inaccuracies exist, the grade and tonnage discrepancy caused by this margin of error is within reasonable doubt for an Inferred Mineral Resource and the estimate is reported
as such.

Recent activities

In November 2016 we commenced a diamond drilling program at our Pickle Crow Project with a focus on identifying new high-grade vein gold mineralization. In February
2017, we announced the results of this exploration drilling program. A total of nine holes comprising approximately 1,300 m were drilled.

The  drill  program  targeted  several  shallow,  high-grade  vein  and  banded  iron  formation  hosted  targets  in  the  core  mine  trend.  The  objective  of  the  program  was  to  test
extensions of known vein zones and discover new high-grade gold mineralization.

Highlights of Fall 2016 Drilling at Pickle Crow:

● Hole PC-16-306 intersected 1.28 g/t Au over 12.70 m including 15.14 g/t Au over 0.70 m in the middle vein zone of the No. 15 Vein.

● Visible gold was intersected in Hole PC-16-306 in the lower vein zone of the No. 15 Vein.

Gold  mineralization  was  encountered  in  seven  of  the  nine  drillholes  and  visible  gold  was  intercepted  in  the  lower  most  vein  zone  of  the  No.  15  Vein  structure.  A  0.30  m
section of drill core from the lower vein zone which included the visible gold was not assayed as it was retained for display purposes, hence the reported intercept of 1.15 g/t
gold over 8.19 m excludes this interval and the 0.30 m section was included at zero grade.

Drill Hole Intercepts from Fall 2016 Drilling at Pickle Crow:

All assays were performed by Accurassay Laboratories of Thunder Bay, Ontario. Samples were analyzed by using 50 g fire assay with an atomic absorption finish. Samples
greater than 10 g/t or with visible gold were analyzed by 1,000 metallic analysis with a gravimetric finish. All assays reported are uncut. Reported widths are drilled core
lengths, and true widths are unknown at this time. Accurassay Laboratories is independent of First Mining and has no relationship with First Mining.

QA/QC Procedures

NQ diameter (47.6 mm) drill core was logged then sawn in half on-site, with one half bagged and labelled and the other half placed in core boxes to serve as a permanent
record and stored in a secure on-site facility. All samples were shipped from site via Manitoulin Transport to the Accurassay Laboratories facility in Thunder Bay, Ontario, for
crushing, pulverization and pulp preparation. Accurassay Laboratories is independent of First Mining and has no relationship with First Mining.

All samples sent for analyses were prepared using a jaw crusher, which is cleaned with compressed air between samples, resulting in 70% of the sample passing through a 10
mesh screen. A 1,000 g split of the crushed sample was then pulverized with 85% passing through a 200 mesh screen. Fire assays were performed using 50 g of samples with
assays  equal  to  or  greater  than  5  g/t  calculated  gravimetrically,  and  lower  grade  samples  measured  by  atomic  absorption  (AA).  All  samples  greater  than  10  g/t  were
additionally sent for screen metallics analysis using the remainder of the pulp (~950 grams of sample). Blanks, standards (one high-grade, one mid-grade, and one low-grade),
field duplicates (1/4 split cores), and crush duplicates were inserted into the drill core samples sequentially, at least every 8th sample, before shipment. Standards consisted of a
high-grade (~13 g/t Au), a mid-grade (~5 g/t Au), and a low-grade (~1 g/t Au) gold standard from Geostats Pty. Ltd. of Fremantle, Western Australia, as well as blanks from
Nelson Granite of Kenora, Ontario.

Recent developments

On March 12, 2020, the Company announced that it had entered into the Pickle Crow Earn-In Agreement with Auteco pursuant to which Auteco may earn up to an 80%
interest PC Gold, which owns the Pickle Crow Project. During the term of the agreement, Auteco will be the operator of the Pickle Crow Project and will be responsible for
all expenditures. For a summary of the key terms of the Pickle Crow Earn-In Agreement, see the section in this AIF entitled “Investor information – Material contracts”.

Since entering into the Pickle Crow Earn-In Agreement, Auteco has completed 84 diamond drill holes at the Pickle Crow Project totalling 19,400 m, with such holes focused
exclusively on near mine extensions and mineralized structures outside of the current resource area. These holes are part of a 45,000 m drill program, utilizing five diamond
drill rigs, that is currently being undertaken by Auteco at the Pickle Crow Project. Once the current drill program has been completed, Auteco plans to transition to a drill
program aimed at infill drilling and resource definition in order to provide sufficient data density to update the current Mineral Resource estimate for the Pickle Crow Project.

Recent Pickle Crow Drill Highlights

The  current  phase  of  drilling  by  Auteco  has  successfully  intersected  extensions  to  known  mineralized  structures,  in  addition  to  the  discovery  of  previously  undefined
mineralization. Recent drill highlights include:

● 5.6 m @ 33.4 g/t gold from 20.3 m in hole AUDD0078 (Shaft 3 Veins) – New Structure

(includes 3.4 m @ 51.3 g/t gold from 20.3 m) with individual assay grades of up to 117 g/t gold and 109 g/t gold (0.4 m @ 117 g/t gold from 21.3 m and 0.3 m @
109 g/t gold from 22.8 m)

● 1.6 m @ 16.9 g/t gold from 12.7 m in hole AUDD0077 (Shaft 3 Veins) – New Structure

(includes 0.7 m @ 36.6 g/t gold from 13.6 m)

● 2 m @ 8.2 g/t gold from 396.5 m in hole AUDD0056 (Shaft 1 Veins) – Extension of Structure

● 4 m @ 5.9 g/t gold from 420 m in hole AUDD0056 (Shaft 1 Veins) – Extension of Structure

Notes:

● Assaying for the Auteco drill program was completed by AGAT laboratories in Thunder Bay, Ontario.

Prepared 30 g samples were analyzed for gold by lead fusion fire assay with an atomic absorption spectrometry finish. Samples greater than 5 g/t Au were reassayed by
50 g fire assay with gravimetric finish.

● Reported widths are drilled core lengths; true widths are unknown at this time.
● Cut-off grade of 1 g/t Au allowing for 1 m internal dilution.
● The QA/QC program for the Auteco drill program consists of the submission of duplicate samples and the insertion of Certified Reference Materials (CRMs), including
low,  medium  and  high-grade  standards  and  coarse  blanks,  at  regular  intervals  in  the  sample  stream.  One  set  of  the  four  QA/QC  sample  types  are  inserted  every  25
samples consisting of 1 coarse duplicate, 1 quarter-split field duplicate, 1 CRM (altering between low, medium and high standards) and 1 blank.

Hope Brook

Technical report

The  description  in  this  section  of  our  Hope  Brook  gold  project  (the  “Hope  Brook  Project”)  is  based  on  the  project’s  technical  report:  2015  Mineral  Resource  Estimate
Technical  Report  for  the  Hope  Brook  Gold  Project,  Newfoundland  and  Labrador,  Canada  (effective  date  January  12,  2015,  report  date  November  20,  2015)  (the  “Hope
Brook  Technical  Report”).  The  report  was  prepared  for  us  by  Mercator  Geological  Services  in  accordance  with  NI  43-101  under  the  supervision  of  Michael  P  Cullen,
P.Geo.; a Qualified Person within the meaning of NI 43-101. The following description has been prepared under the supervision of Hazel Mullin, P.Geo., who is a Qualified
Person within the meaning of NI 43-101, but is not independent of us.

The  conclusions,  projections  and  estimates  included  in  this  description  are  subject  to  the  qualifications,  assumptions  and  exclusions  set  out  in  the  Hope  Brook  Technical
Report, except as such qualifications, assumptions and exclusions may be modified in this AIF. We recommend you read the Hope Brook Technical Report in its entirety to
fully understand the project. You can download a copy from our SEDAR profile (www.sedar.com), or from our website (www.firstmininggold.com).

Property description, location and access

The Hope Brook Project is located on the southwest coast of the island of Newfoundland, in the province of Newfoundland and Labrador, Canada. It is comprised of a core
holding of 1,003 contiguous exploration claims originally acquired through map staking and issued in 2003 and 2008. This main property covers 25,075 ha of surface area
and measures approximately 32 km by 12 km in maximum east-west and north-south dimensions, respectively. Constituent claims are held under 5 separate mineral licenses
and the property is approximately centered on the past-producing Hope Brook gold mine, located at Latitude 47.738° north and Longitude 58.095° west. An additional 63
claims (1,575 ha) are held by us in the Ironbound Hill (formerly “Peter Snout”) area, approximately 25 km northeast of the Hope Brook deposit. These were staked in late
2013 to cover areas of exploration potential defined through review of government assessment reporting records.

The Hope Brook Project is located approximately 85 km by water east of the community of Port aux Basques and is not accessible by any form of highway transportation at
this time. Direct site access to the Hope Brook Project can be gained by chartered boat from either the Burgeo or Port aux Basques areas and could also be gained through
small boat charter from La Poile, after travel to that community on the coastal service vessel. The most efficient means of current access to the property is by charter fixed
wing aircraft or helicopter from commercial bases in the Deer Lake- Pasadena area, approximately 120 km to the north.

Coastal Gold earned a 100% interest in 993 claims of the original Hope Brook Project property by fulfilling requirements of an option to purchase agreement dated January
25, 2010.

As of the date of the Hope Brook Technical Report, two exploration permits by the government of Newfoundland and Labrador were required for bedrock core drilling and
vibracore  tailings  drilling  programs  as  well  as  geochemical  and  geophysical  surveys,  valid  until  April  15,  2015  and  June  17,  2015,  respectively.  It  is  anticipated  that  new
permits will be required if we chose to initiate certain site-based aspects of the Phase I or Phase II work programs recommended in the Hope Brook Technical Report. In
addition, the License to Occupy for the Hope Brook exploration camp was being reviewed by government at the effective date of the Hope Brook Technical Report, with
timely  issuance  expected.  No  substantive  difficulties  have  been  encountered  to  date  with  respect  to  procurement  of  required  Exploration  Permits  and  camp  occupancy
permissions.

A  2%  net  smelter  returns  royalty  payable  applies  under  terms  of  a  royalty  pre-payment  schedule  of  $20,000  per  year.  All  royalty  pre-payment  funds  provided  under  the
agreement are to be accounted for against future production. We retain a right during the term of the agreement to purchase one half of the 2% NSR royalty for $1,000,000.

Annual work requirements for each claim are set out under the province’s Mineral Act and range from $200 per claim in year one to $1,200 per claim in years 16 through 20.
In addition, a renewal fee of $25 – $100 is payable for each claim on a five-year basis.

As part of the 2011 work program a screening level assessment of baseline environmental conditions was carried out at the Hope Brook Property. Results of this study showed
that a number of chemical impacts that are residual to the former mining operation are present locally. These include elevated metal levels in soil, sediment and water as well
as elevated petroleum hydrocarbon levels in soil. The most significant liabilities were deemed to be associated with subsurface conditions where impairment to both soil and
groundwater had occurred around existing landfill sites, the heap leach pad, and within the underground mine workings. All of these conditions pre-date Coastal Gold site
activities and therefore we are excluded from associated liability. However, if a new mining venture is established at this site it will be necessary to fully quantify the potential
impacts of such conditions on site development, mining and site decommissioning and reclamation plans for the new operation. All such issues would be dealt with under the
mine permitting and associated environmental approval processes.

History

Documentation of Hope Brook Project area’s history of exploration and mining spans the period between 1923 and the present day, but modern programs directed toward
assessment of gold potential and related mining have only occurred since discovery of the Hope Brook gold deposit in 1983.

Programs of deposit definition drilling, resource estimation, metallurgical assessment and feasibility assessment were completed for the Hope Brook deposit between 1984
and 1986 and a production decision was announced in 1986. The deposit was subsequently developed and mined during the period of 1987 through 1991. The production
decision  appears  to  have  been  supported  by  initial  resources  of  11.2  million  tonnes  grading  4.54  g/t  Au  above  a  2.5  g/t  Au  cut-off  (~1.6  million  troy  ounces)  that  were
reported. Additionally, the same tonnage and gold grade was separately reported for the deposit but additionally specified a 0.3% copper parameter.

Mining from both open pit and underground operations was ultimately carried out between 1987 and 1997. Provincial government records document production of 304,732
ounces of gold during the 1987-1991 period from all operations. Difficulties with elevated cyanide and copper levels were encountered in processing plant effluent during the
operating period and this may have contributed to cessation of mining and milling in early 1991.

During the 1987-1991 mining period, detailed exploration focus was largely restricted to the mine area and adjoining advanced argillic alteration zone (“AAZ”) areas to the
southwest, with particular attention paid to assessment of possible strike and dip extensions of the main deposit.

From 1991 to mid-1997, underground mining at the site was carried out. Operations ceased in mid-1997. Production of 447,431 ounces of gold was recorded during the 1992-
1997 period. Re-assessments of past exploration programs was carried out in both the mine area and surrounding district and follow-up exploration on several promising areas
not associated with the AAZ and the Hope Brook deposit trend was completed. No substantial new discoveries were made during this period.

During the period 2002 through 2007 the provincial government carried out environmental assessment and reclamation programs at the Hope Brook mine site. No mining
activities have been carried out subsequent to those of carried out from 1991 to 1997.

No drilling-based exploration programs were completed on the Hope Brook Project through the period 1997 through 2007. However, in 2003 mine area exploration holdings
were staked by related entities.

Beginning in 2008, an airborne magnetometer and electromagnetic survey of the entire property was carried out, past drilling results were compiled, prospecting was carried
out and an extensive bedrock sampling program was completed. Sampling was substantially focused in an area immediately northwest of the Hope Brook open pit where
alteration zone and silicified zone units occurring structurally below the mined Hope Brook deposit had been exposed during removal of acid generating waste rock during
the site reclamation program. No substantial new discoveries resulted from any of this work.

Since the start of exploration work in 2010, Coastal Gold carried out programs of drill core physical properties investigation, ground geophysics, environmental screening,
data  compilation,  data  validation,  core  drilling,  vibracore  tailings  drilling,  bedrock  and  tailings  mineral  resource  estimation,  metallurgical  assessment  and  general  property
evaluation.

From April 2010 through December 2014, Coastal Gold completed systematic gold exploration programs, primarily focused in the area surrounding the past producing Hope
Brook mine.

Geological setting, mineralization and deposit types

The Hope Brook Property occurs within a tectonically complex zone that has been interpreted by some to occur within the Avalon Zone of the Appalachian Orogen (or a
related Avalon Composite Terrane), near its generally east-west trending tectonic contact with adjacent rocks of the Dunnage Zone. The Avalon Zone represents a late Neo-
Proterozoic assemblage of active plate margin sequences that accumulated prior to development and closure of the Lower Paleozoic Iapetan Oceanic system. Sequences of
Avalonian  affinity  occur  throughout  much  of  the  Appalachian  Orogen,  and  extend  from  the Avalon  Peninsula  and  southwest  coast  areas  of  Newfoundland,  through  Nova
Scotia, New Brunswick and northern New England. From that point southward, more discontinuously distributed outcropping segments occur as far as northern Georgia and
subsurface extensions are interpreted to be present in Florida. Onshore exposures of confirmed Avalon Zone affinity are limited in comparison with its interpreted width of at
least 600 km in the eastern offshore area of Newfoundland and Labrador.

The geological aspects of the Avalon Zone, particularly in context of magmatic history represented in the Newfoundland, consist of four major tectono- stratigraphic events.
Most  significant  of  these  from  the  perspective  of  magmatic  activity  is  the  period  when  substantial  volumes  of  volcanic  and  plutonic  rocks  evolved  under  back-arc  or
continental arc settings, sometimes in broad association with terrestrial or marine siliciclastic sequences. These are related in time with development of auriferous, high level
hydrothermal alteration systems along the entire length of the Avalon Zone and the Hope Brook gold deposit may be an example of this metallogenic association.

The Hope Brook gold deposit and associated AAZ are of primary importance with respect to the Hope Brook Project. However, several other bedrock gold occurrences are
present within the Hope Brook Project that differ from Hope Brook. The most prominent examples of such are those in the Old Mans Pond, Phillips Brook and Cross Gulch
areas.  Each  of  these  areas  has  been  investigated  through  historic  exploration  programs  that  typically  included  geological,  geophysical  and  geochemical  surveys,  surface
trenching and limited amounts of core drilling. Drilling has locally confirmed subsurface gold-bearing intervals in each area but mineralized zones of economically significant
proportions have not been defined to date. The Hope Brook style of mineralization is considered to be most important. The Hope Brook gold deposit is a large, disseminated
gold-chalcopyrite-pyrite  deposit  hosted  by  highly  altered  sedimentary  and  volcano-sedimentary  rocks  of  the  late  Proterozoic  Whittle  Hill  Sandstone  and  Third  Pond  Tuff
successions,  similarly  altered  felsic  porphyry  dikes  and  sills  related  to  the  Roti  Intrusive  Suite  and  variably  altered  later  mafic  dikes  and  sills.  Zones  hosting  gold
mineralization of economic interest typically bear evidence of intense silicification and occur within the AAZ, a broad envelope of advanced argillic alteration that can be
traced for up to 8 km southwest of the deposit.

83

 
 
 
 
 
 
 
 
 
 
 
 
 
The  Hope  Brook  gold  deposit  is  currently  one  of  the  largest  gold  deposits  in  the  Canadian  Appalachians,  based  on  historic  resources  and  production.  As  noted  earlier,  it
occurs  within  a  zone  of  extensive  AAZ  hosted  by  late  Proterozoic  sedimentary,  volcanic  and  intrusive  rocks.  Recent  work  by  Coastal  Gold  has  added  to  the  technical
documentation of alteration and mineralization that characterize the deposit. Intense hydrothermal alteration and spatially associated silicification have been identified as key
components of the mineralizing system that gave rise to the deposit. However, differences exist with respect to interpreted placement of the Hope Brook mineralizing system
in the time/space context of the orogen and some of these bear directly on deposit classification.

In  addition  to  the  Hope  Brook  deposit,  several  gold  occurrences  associated  with  Silurian  or  younger  sericitic  alteration,  quartz  veining  and  silicification  have  also  been
documented within the Hope Brook Project area. None of these is substantial in size or gold grade as presently defined, but spatial association with the large Bay d’Est Fault
or its secondary splays, and possibly with Silurian magmatic activity, indicates that potential for more significant mineralization is present.

Exploration

No new exploration work has been undertaken to date by us on the core Hope Brook property. The Hope Brook Technical Report and associated Mineral Resource estimate
review reflect the first NI 43-101 technical reporting by us for the Hope Brook property.

Drilling

Between September 2010 and October 2013, Coastal Gold completed in five separate drilling programs 139 diamond drillholes and drillhole extensions on the Hope Brook
Property that total 39,320.4 m of drilling.

Coastal Gold completed 10 surface diamond holes totalling 3,421.9 m in length between September 2010 and January 2011 which successfully confirmed the presence of
disseminated gold-chalcopyrite-pyrite mineralization hosted by highly silicified sedimentary and volcano-sedimentary rocks both at depth, below the 4800 level of historic
mining, and at surface to the southwest of the historic open-pit. An exploratory drillhole targeting mineralization along the northeast extension of the mine at depth returned
no significant results and an exploratory drillhole targeting the 240 Zone caved short of the target.

Another surface drilling campaign was completed between February 2011 and December 2011 that consisted of 67 holes totalling 21,350.5 m. The program was successful in
demonstrating continuity of disseminated gold-chalcopyrite-pyrite mineralization hosted by highly silicified volcano-sedimentary rocks in all three targeted areas of drilling
and provided the drillhole density required for resource estimation.

Between February 2012 and May 2012 Coastal Gold completed a surface drill program that consisted of 15 holes, re-drills and hole extensions totalling 4,549 m in length.
This  program  focused  on  confirming  the  locations  of  workings  and  major  pillars  in  the  mine  area,  further  testing  of  the  Southwest  Extension  target  area  and  preliminary
testing of the Northeast target area.

84

 
 
 
 
 
 
 
 
 
 
 
 
The fourth Hope Brook drilling program by Coastal Gold began on November 3, 2012 and was completed on December 21, 2012. A total of 5,923.9 m of drilling in twenty-
one drillholes were completed. Six separate targets areas, along a 3.4 km long mineralized trend, were drilled during the program including the Stope 4960-150, the 240 Zone
– Mine Zone Connector Target, the Chetwynd Prospect and the Chetwynd South Prospects, the Chetwynd to 240 Connector Target and the NW Target Area. The drilling was
completed in these areas in order to continue to expand on the area of known gold mineralization outside of the current Hope Brook Deposit area.

The fifth drill program at the Hope Brook Property began on August 9, 2013 and was completed on October 10, 2013. A total of 4,075.2 m of drilling in twenty-six drillholes
were completed. The drill program was designed to test two major target areas; the Footwall Target and SW Pit Extension Target.

A systematic vibracore tailings drilling program on two tailing ponds at the Hope Brook site was carried out during the September through October period of 2013 and a total
of 73 vibracore drillholes totalling 155 m were completed on an approximate 100 m square grid over the two tailings ponds. The purpose of the program was to evaluate the
thickness and gold grade of the tailings and to provide sufficient data to support a NI 43-101 compliant Mineral Resource estimate of the contained gold and copper. Of the
holes completed, 51 successfully sampled tailings, with thicknesses of the tailings sections ranging from 0.3 to 6.0 m. Average thickness of cored tailings was 3.0 m.

Sampling, analyses and data verification

Coastal Gold staff members were responsible for arranging transport of core boxes from the drilling sites to the company’s secure core storage and logging facility located at
the  Hope  Brook  camp.  The  core  was  initially  examined  by  core  technicians  and  all  measurements  are  confirmed.  Core  was  then  aligned  and  repositioned  in  the  core  box
where possible and individual depth marks are recorded to facilitate logging. Core technicians photographed all core, measured core recovery between core meterage blocks,
carried  out  water  immersion  specific  gravity  measurements  as  required  and  recorded  information  on  hard  copy  data  record  sheets  that  were  then  entered  into  the  project
drilling database.

All paper copy and digital information for each hole, including quick logs, sample record sheets and assay certificates were maintained in a secure filing system at the site to
provide a complete archival record for each drillhole. Digital information was stored on a local server as well as on the company’s secure off-site server that was accessible by
satellite link from the camp facility. Subsequent to logging and processing, down hole lithocoded intervals, sample intervals and drillhole collar and survey information that
were  entered  into  the  digital  database  were  checked  for  completeness  before  being  uploaded  to  the  project  database  upon  which  drilling  section  generation  and  three-
dimension deposit modeling were based.

The  secured  plastic  sample  bags  were  grouped  in  batches  40  to  which  QA/QC  program  samples  were  added  prior  to  final  packing  for  shipment  to  the  ALS  preparation
laboratory in Sudbury, ON. Samples were transported from the site by aircraft or chartered boat and then delivered to a commercial transport service for final delivery to the
laboratory. Sample shipment change of custody forms were used to list all samples in each shipment and laboratory personnel crosschecked samples received against this list
and reported any irregularities by fax or email to Coastal Gold.

Primary project analytical work was completed by ALS with preparation taking place at ALS’ Sudbury, ON facility and subsequent analysis at the facility in Vancouver, BC.
ALS is an internationally accredited laboratory with National Association of Testing Authorities certification and also complies with standards of ISO 9001:2000 and ISO
17025:1999. The laboratory utilizes industry standard analytical methodologies and rigorous internal Quality Assurance and Quality Control (“QA/QC”) procedures for self-
testing.

All Hope Brook Project core samples were weighed upon receipt at the ALS preparation laboratory and prepared using ALS preparation procedure PREP-31B that consists of
crushing  the  entire  sample  to  >70%  -2  mm,  then  splitting  off  1  kg  and  pulverizing  it  to  better  than  85%  passing  75  microns  size.  The  coarse  reject  materials  from  this
processing were stored for future use.

85

 
 
 
 
 
 
 
 
 
 
 
 
Gold concentrations for submitted core and rock samples were determined by ALS using a 50 g sample split and fire assay pre-concentration methods followed by atomic
absorption  spectroscopy  finish  (FA-AAS). This  is  reflected  in  ALS  code  Au-AA24.  A  33-element  analysis  was  also  completed  on  selected  samples  by  method  code  ME-
ICP61 which denotes four acid digestion followed by inductively coupled plasma – atomic emission spectroscopy (ICP-AES) analysis.

Drill  core  sampling  carried  out  by  Coastal  Gold  during  the  September  2010  through  July  2012  period  on  the  Hope  Brook  Property  was  subject  to  a  QA/QC  program
administered by Coastal Gold. This included submissions of blank samples, use of certified reference materials and analysis of pulp and coarse reject check sample splits at a
third party commercial laboratory.

The 2012 piston sampling program and 2013 vibracore drilling program of historic Hope Brook Property mine tailings deposits were also subject to a systematic QA/QC
program carried out by Coastal Gold.

All of the drill core programs for the period from October 2012 through to November 2013 were subject to essentially the same QA/QC protocols as had been applied to the
earlier core drilling campaigns referred to above. This included systematic submission of blank samples, use of certified reference materials and analysis of pulp and, for core,
coarse reject check sample splits at a third party commercial laboratory. Results of both the in-house and laboratory quality control and assurance analyses were monitored by
Coastal Gold on an on-going basis and were also made available for review by Mercator Geological Services Limited (“Mercator”). A QA/QC protocol was also established
for the vibracore drilling program and this included systematic analysis of certified reference materials, duplicate sample splits, blank sample materials and analysis of third-
party pulp split check samples.

The  drill  core  samples  were  packaged  in  batches  of  40  samples,  which  included  one  blank  sample  (10th sample), one pulp duplicate (20th  sample),  one  certified  reference
material  sample  (30th  sample)  and  one  coarse  reject  duplicate  sample  (40th  sample).  ALS  provided  primary  analytical  services  for  the  project  while  pulp  duplicate  (20th
sample) and coarse reject duplicate (40th sample) splits were analyzed at SGS to provide independent laboratory check sample data sets. SGS is a commercial, ISO certified
laboratory independent of Coastal Gold.

After  standard  crushing  and  pulverization  of  bedrock  core  samples,  gold  analysis  was  by  atomic  absorption  methods  after  fire  assay  pre-concentration  and  multi-element
determinations were by inductively coupled plasma - optical emission spectroscopy methods after four acid total digestion. One certified reference material sample and one
blank sample were included in the core sample shipment. The tailings samples were separately processed from the core samples and were also accompanied by one certified
reference material sample and a blank sample. Results of the QA/QC program for these samples were acceptable.

Core sample records, lithologic logs, laboratory reports and associated drillhole information for all drill programs completed were digitally compiled by Coastal Gold staff
and made available for previous resource estimation purposes. Information pertaining to the exploration history in the property area had already been compiled by Mercator
and  was  reviewed  in  conjunction  with  newly  generated  records  to  assess  completeness,  consistency  and  validity  of  compiled  results.  This  progressively  compiled  and
validated information is acceptable for resource estimation purposes.

Database  records  for  previously  validated  historic  drillholes  were  modified  by  Coastal  during  2013  through  addition  of  copper  analytical  data  recovered  from  archival
records. All such amendments were checked against source documents by Mercator and through spot checks by AGP prior to use in the current resource estimation program
and no errors were noted.

In addition to the above, records for 47 new diamond drillholes completed by Coastal Gold during 2012 and 2013 were reviewed and validated by Mercator for addition to the
project  database  and  used  in  the  previous  and  current  resource  estimation  programs.  Digital  records  were  checked  against  original  source  documents  provided  by  Coastal
Gold  and  both  consistency  and  accuracy  of  such  records  were  assessed.  Parameters  reviewed  in  detail  include  collar  coordinates,  down  hole  survey  values,  hole  depths,
sample intervals, assay values and lithocodes. All 47 of the 2012 and 2013 holes completed by Coastal Gold were checked for correlation of sample interval, assay value and
lithocode information against source documents. This review showed consistently good agreement between original records and digital database values for all data sets.

86

 
 
 
 
 
 
 
 
 
 
 
 
In 2013, Coastal added 152 historical short core holes (“OP” series holes) to the project database. These holes have not been validated by Mercator and were excluded from
use in the previous and current resource estimates. After completion of manual checking procedures, all drillhole database records were further assessed through digital error
identification methods available through the Gemcom-Surpac Version 6.2.1® software. This provided a check on items such as sample record duplications, end of hole errors,
survey and collar file inconsistencies and some potential lithocode file errors. The digital review and import of the manually checked datasets provided a validated drillhole
database to support the resource estimation program described in the Hope Brook Technical Report.

Coastal Gold completed several core drilling holes during the 2010-2011 drilling programs to serve as twins to historic holes. These were typically planned to provide more
complete  lithological  and  assay  information  for  associated  historic  holes  and  to  provide  a  basis  for  comparison  of  the  historic  datasets  with  Coastal  Gold  data.  For  the
purposes of the Hope Brook Technical Report, 12 Coastal Gold holes that were completed in sufficiently close proximity to historic holes to provide such assessment were
selected for comparison with the Coastal Gold data.

For  assessment  purposes,  Mercator  reviewed  drill  log  lithocodes  and  gold  assay  entries  for  hole  pairs  to  determine  the  level  of  consistency  between  the  two  datasets.
Assessment of lithocodes focused primarily on identification of important silicified zone intervals associated with gold mineralization and secondarily on logged intervals of
mafic dike material. Comparison of the assay data on a sample by sample basis was not typically possible due to either spatial separation of hole traces, differing sample
lengths or presence of non-sampled intervals in some holes. Comparison of lithocoded intervals between hole pairs showed that good correlation between data sets exists.
However, greater detail in silicic lithocoding characterises the historic dataset prior to re-coding by Coastal Gold.

As noted above, comparison of assay values between hole pairs was affected in some instances by presence of un-sampled intervals within the historic holes that contrast to
continuously sampled Coastal Gold intervals, by differing mafic material percentages and by differing interpreted assay zone widths. Mercator focused on gold assay data
within  the  gold-bearing  silicified  zone  lithologic  units  and  created  weighted  average  intervals  to  support  comparison.  Results  of  this  program  for  the  12  holes  considered
showed that spatial definition of the gold zones based on assay boundaries is typically consistent between hole pairs and this is reflected in generally comparable intercept
lengths selected.

The weighted average Coastal Gold data set results are typically higher than equivalent intervals in historic holes but the reverse is also seen in some cases. Mercator believes
that several factors contribute to this result, including changes in mafic dike dilution between holes, higher overall core quality of the NQ and BQTK size Coastal Gold core
relative  to  the  historic  BQ  core,  and  higher  overall  core  recovery  for  Coastal  Gold  holes  in  fractured  intervals  of  the  mineralized  zone.  Heterogeneity  of  primary  gold
distribution is also a potential contributor.

Based on results of the twin hole comparison originally carried out in support of earlier resource estimates, at the effective date of the Hope Brook Technical Report Mercator
remains of the opinion that acceptable consistency exists between these hole pairs with respect to gold assay value and lithocode data sets.

Mineral processing and metallurgical testing

Scoping level metallurgical test work on mineralized samples was first carried out for Coastal by G&T Metallurgical Services Ltd. (“G&T”) in Kamloops, BC in 2012. The
objectives of that program were to evaluate potential processing routes for maximizing gold recovery and to identify operating parameters for the preliminary circuit design.
Flotation test work was successful at generating a concentrate grading 28% Cu from flotation of cyanidation residue in a process similar to the historical flowsheet at Hope
Brook. Gravity concentration tests indicated that between 16 and 41% of the contained gold was recoverable to concentrate by this method. Combined gold recoveries of
~86% were achieved using a flowsheet consisting of gravity concentration followed by cyanidation of the gravity tailings. Direct cyanidation of tailings resulted in up to 49%
extraction of contained gold.

87

 
 
 
 
 
 
 
 
 
 
Additional metallurgical testing was carried out by G&T in the fall of 2013 to further advance the understanding of the metallurgy of the Hope Brook deposit. This included
batch flotation test work focused on the opportunity to recover a saleable grade copper concentrate after the grinding and gravity recovery step. Scoping level test work was
also carried out at Tomra Sorting Solutions in Surrey, BC to evaluate the potential of rejecting dilution material before the grinding area using sensor-based sorting. Sorting
program results indicated that the mafic dyke dilution was readily distinguished from the mineralized rock using four separate detector systems, indicating that this material is
highly amenable to rejection by sorting.

Mineral resource estimates

The Mineral Resource estimate for the Hope Brook Project is based on a three-dimensional block model developed using Geovia – Surpac Version 6.1.1® deposit modeling
software and a matrix size of 10 m (X) by 5 m (Z) by 3 m (Y). Grade interpolation utilized multiple pass ordinary kriging methodology with an inverse distance squared
check model used for validation. Classification of the resource followed the approach used in the 2014 NI 43-101 Mineral Resource estimate and was based primarily on
interpolation pass number, distance to the closest informing assay composite and kriged variance. The 3 g/t Au cut-off value used is substantially higher than cut off values of
Coastal  Gold’s  previous  Mineral  Resource  estimates  that  were  focused  on  optimization  of  open  pit  mining  scenarios.  Current  Mineral  Resources  are  considered  to  have
reasonable potential for economic viability based on application of underground mining methods, historic gold recovery levels that range between 80% and 91% percent for
past  production  (86%  for  Coastal  Gold  testing)  and  a  long-term  gold  price  of  US$1,200  per  ounce.  This  estimate  of  Mineral  Resources  may  be  materially  affected  by
environmental, permitting, legal, title, taxation, socio-political, metal pricing, marketing, or other relevant issues.

Non-material properties

We also hold a number of non-material mineral properties in our portfolio. Some of these properties are resource-stage assets which have NI 43-101 technical reports that
support resources of less than one million ounces of attributable gold. Others are grassroots exploration projects that host mineralization but have not had sufficient drilling on
them to classify resources under the CIM definition standards. A brief summary of some of these properties is set out in this section.

Canada

Duquesne Gold Project, Québec

We acquired a 100% interest in the Duquesne Gold project located in the Abitibi Region of Québec (the “Duquesne Project”) through our acquisition of Clifton Star in April
2016. The Abitibi Region of Québec is one of the most prospective and productive mineral regions in Canada with more than 100 years of continuous mining history and
hosts a number of major Canadian mines.

The property, which comprises 85 contiguous mining claims and one mining concession, covers an area of 2,180 ha and is situated along the Destor-Porcupine Break, which
boasts  historical  production  of  192  million  oz.  Au.  It  is  approximately  30  km  northwest  of  the  city  of  Rouyn-Noranda,  and  approximately  16  km  east  of  the  town  of
Duparquet, so it has excellent access to infrastructure and a skilled labour pool.

The Duquesne Project hosts, an NI 43-101 Indicated Mineral Resource of 1.9 Mt grading 3.33 g/t Au, containing 199,000 oz. Au, and an Inferred Mineral Resource of 1.6 Mt
grading  5.58  g/t  Au,  containing  281,000  oz.  Au.  The  technical  report  in  support  of  these  Mineral  Resources,  entitled  “43-101  Technical  Report  Resource  Estimate  of  the
Duquesne Gold Property”, was prepared by Genivar Limited Partnership in accordance with NI 43-101 and was dated July 26, 2011 and filed on SEDAR by Clifton Star on
October 28, 2011 under its SEDAR profile.

Pitt Gold Project, Québec

We purchased a 100% interest in the Pitt Gold project located in the Abitibi Region of Québec (the “Pitt Project”) from Brionor in April 2016. The property, which comprises
14 contiguous mineral claims, covers an area of 492 ha.

The Pitt Project is close to our Duquesne Project, and to the Duparquet Gold Project located in the Abitibi Region of Québec (in which we hold an indirect 10% interest). It is
approximately 35 km north of the city of Rouyn-Noranda, and approximately 7 km east of the town of Duparquet, so it has excellent access to infrastructure and a skilled
labour pool.

The Pitt Project hosts an NI 43-101 Inferred Mineral Resource of 1,076,000 tonnes grading 7.42 g/t Au (at a cut-off grade of 3.0 g/t Au), containing 257,000 oz. Au. The
technical  report  in  support  of  these  resources,  entitled  “NI  43-101  Technical  Report  and  Review  of  the  Preliminary  Mineral  Resource  Estimate  for  the  Pitt  Gold  Project
Duparquet Township Abitibi Region, Quebec, Canada”, was prepared in accordance with NI 43-101 by Micon International Ltd., with an effective date of December 6, 2016,
and was filed by us on SEDAR on January 6, 2017 under our SEDAR profile at www.sedar.com.

Duparquet Gold Project, Québec

We have a 10% indirect interest in the Duparquet Gold Project which has a large open-pittable resource, as well as underground and tailings resource. Our interest in the
Duparquet  Gold  Project  was  acquired  through  our  acquisition  of  Clifton  Star.  The  Duparquet  Gold  Project  covers  an  area  of  1,147  hectares  and  is  located  in  the  Abitibi
Region of Québec which is one of the world's most prolific gold producing regions.

The Duparquet Gold Project hosts Measured Mineral Resources of 184,700 tonnes grading 1.52 g/t Au, containing 9,006 oz. Au, Indicated Mineral Resources of 60.6 Mt
grading 1.59 g/t Au, containing 3.1 million oz. Au and Inferred Mineral Resources of 29.7 Mt grading 1.51 g/t Au, containing 1.4 million oz. Au. The technical report entitled
“Technical Report and Prefeasibility Study for the Duparquet Project” was completed by InnovExplo, with an effective date of March 26, 2014 and was filed on SEDAR by
Clifton Star on May 23, 2014.

As  well  as  our  10%  indirect  interest  in  the  Duparquet  Gold  Project,  we  also  hold  a  100%  interest  in  the  adjoining  Central  Duparquet  Property,  which  was  purchased  on
January 20, 2017. This additional ground comprises 16 claims covering 339 ha. A technical report entitled “Technical Report and Mineral Resource Estimate Update for the
Duparquet Project” was completed by InnovExplo, with an effective date of June 26, 2013 and a signature date of August 2, 2013.

Infrastructure includes site roads, access to electrical power 15 km away, tailings storage facility and water management solutions and ancillary site buildings. The Duparquet
Gold Project is currently comprised of three mineral properties: Beattie, Donchester and Dumico. The 2014 prefeasibility study includes pre-production capital costs of $394
million, a pay-back period of 4.3 years and pre-tax NPV (5%) of $222 million at US$1,300 per ounce of gold.

Goldlund Gold Project, Ontario

In connection with the Treasury Metals Transaction, we were granted a 1.5% NSR royalty over all of the claims that comprise the Goldlund Project (which is now owned by a
subsidiary of Treasury Metals). The Goldlund Project is an exploration stage property located in northwestern Ontario. Treasury Metals has the option to buy-back 0.5% our
royalty by paying us $5 million in cash. For further details regarding the Treasury Metals Transaction, see the section in this AIF entitled “Investor information – Material
contracts – Treasury Metals SPA”.

The Turquoise Canyon property (formerly the Bald Mountain property) located in Nevada is wholly-owned by First Mining. The property covers an area of 1,562 hectares
and is located along the Battle Mountain-Eureka Trend, 16 km south of Barrick Gold Corp.'s Cortez Mine Complex (23 Moz. Au), and 9 km west of its newly discovered
Gold Rush deposit (7 Moz. Au) and 1.5 km east of the Toiyabe Mine, a Carlin type gold deposit that produced 89,000 oz. of gold in the 1990s.

Results  of  an  airborne  ZTEM  survey  commissioned  by  the  Company  show  an  antiformal  structure  in  the  underlying  Roberts  Mountain  Thrust  which  will  be  the  focus  of
future exploration. A gravity high and anomalous conductive/polarizable anomalies at the southwest corner of the property are high priority drill targets. Six other potential
drill targets were interpreted from two induced polarization/resistivity lines run over the property.

The  Company  entered  into  an  option  agreement  (the  “Turquoise  Canyon  Option Agreement”)  dated  August  20,  2019  with  Momentum  Minerals  Ltd.  (“Momentum”)
granting Momentum the right to earn a 100% interest in the Turquoise Canyon property. Pursuant to the Turquoise Canyon Option Agreement, First Mining will receive up to
$500,000 in aggregate proceeds from Momentum as follows:

● 10% of the current outstanding common shares of Momentum (value to be determined at the time of issuance);

● $25,000 cash within 30 days of signing the agreement;

● First anniversary: $50,000 in cash or Momentum common shares;

● Second anniversary: $150,000 in cash or Momentum common shares;

● Third anniversary: Half of the remaining amount owing in cash or Momentum common shares; and

● Fourth anniversary: Remaining amount owing in cash or Momentum common shares.

The  annual  consideration  payments  of  cash  or  Momentum  common  shares  will  be  at  Momentum’s  election.  Beginning  in  2020,  Momentum  will  also  be  responsible  for
paying all annual concession tax payments with respect to the Turquoise Canyon property to the Nevada State land management authorities.

In addition to the payment terms outlined above, Momentum will be required to incur exploration expenditures on the Turquoise Canyon property totaling $750,000 over the
four-year option period, incurring at least $50,000 in year one and $100,000 in year two. Upon completion of all payment and expenditure obligations, Momentum will obtain
100%  ownership  of  Turquoise  Canyon  property  and  First  Mining  will  retain  a  2%  NSR  royalty.  Momentum  will  have  the  right  to  buy  back  1%  of  the  NSR  royalty  for
$1,000,000 up until the first anniversary of the commencement of commercial production at the Turquoise Canyon property.

Risks that can affect our business

There are risks in every business.

The nature of our business means we face many kinds of risks and hazards – some that relate to the mineral exploration industry in general, and others that apply to specific
properties, operations or planned operations. These risks could have a significant impact on our business, earnings, cash flows, financial condition, results of operations or
prospects.

The following section describes the risks that are most material to our business. This is not, however, a complete list of the potential risks we face – there may be others we
are not aware of, or risks we believe are not material today that could become material in the future. We have in place systems and procedures appropriate for a company at
our stage of development to manage these risks, to the extent possible, but there is no assurance that we will be successful in preventing the harm that any of these risks could
cause.

Exploration, development, production and operational risks

Exploration and development risks

The exploration for and development of minerals involves significant risks which even a combination of careful evaluation, experience and knowledge may not eliminate.
These risks include:

● few properties that are explored are ultimately developed into producing mines;

● there can be no guarantee that the estimates of quantities and qualities of minerals disclosed will be economically recoverable;

● with all mining operations there is uncertainty and, therefore, risk associated with operating parameters and costs resulting from the scaling up of extraction methods

tested in pilot conditions; and

● mineral exploration is speculative in nature and there can be no assurance that any minerals discovered will result in an increase in our resource base.

Exploration and development of mineral properties is capital intensive and unsuccessful exploration or development programs could have a material adverse impact on our
operations and financial condition.

Operational hazards and risks

Our operations will be subject to all of the hazards and risks normally encountered in the exploration and development of minerals. To the extent that we take a property to
production, we will be subject to all of the hazards and risks associated with the production of minerals. These risks include:

● unusual and unexpected geological formations;

● rock falls;

● seismic activity;

● flooding and other conditions involved in the extraction of material, any of which could result in damage to, or destruction of, mines and other producing facilities,

damage to life or property, environmental damage and possible legal liability;

● environmental pollution, and consequent liability that could have a material adverse impact on our business, operations and financial performance;

● mechanical equipment and facility performance problems; and

● periodic disruptions due to inclement or hazardous weather conditions.

Substantial expenditures

Substantial expenditures are required to establish Mineral Resources and Mineral Reserves through drilling, to develop metallurgical processes to extract the metal from the
ore and, in certain cases, to develop infrastructure at any site chosen for exploration. Although substantial benefits may be derived from the discovery of a major mineralized
deposit, no assurance can be given that minerals will be discovered in sufficient quantities to justify commercial operations or that funds required for development can be
obtained on a timely basis.

The economics of developing mineral properties is affected by many factors including:

● the cost of operations;

● variations in the grade of mineralized material mined;

● fluctuations in metal markets; and

● such  other  factors  as  government  regulations,  including  regulations  relating  to  royalties,  allowable  production,  importing  and  exporting  of  minerals  and

environmental protection.

The remoteness and restrictions on access of properties in which we have an interest will have an adverse effect on expenditures as a result of higher infrastructure costs.
There are also physical risks to the exploration personnel working in the terrain in which our properties are located, occasionally in poor climate conditions.

No history of mineral production

First Mining has no history of commercially producing metals from its mineral exploration properties. There can be no assurance that we will successfully establish mining
operations  or  profitably  produce  gold  or  other  precious  metals  on  any  of  our  properties.  The  development  of  mineral  properties  involves  a  high  degree  of  risk  and  few
properties that are explored are ultimately developed into producing mines. The commercial viability of a mineral deposit is dependent upon a number of factors which are
beyond our control, including the attributes of the deposit, commodity prices, government policies and regulation and environmental protection. Fluctuations in the market
prices of minerals may render Mineral Reserves and deposits containing relatively lower grades of mineralization uneconomic.

While our Springpole Project is currently in development, none of our other mineral properties are currently under development or production. The future development of any
properties  found  to  be  economically  feasible  will  require  applicable  licenses  and  permits  and  will  require  the  construction  and  operation  of  mines,  processing  plants  and
related  infrastructure.  As  a  result,  the  development  of  any  property  will  be  subject  to  all  of  the  risks  associated  with  establishing  new  mining  operations  and  business
enterprises, including, but not limited to:

● the timing and cost of the construction of mining and processing facilities;

● the availability and costs of skilled labour and mining equipment;

● the availability and cost of appropriate smelting and/or refining arrangements;

● the need to obtain necessary environmental and other governmental approvals and permits and the timing of those approvals and permits; and

● the availability of funds to finance construction and development activities.

It  is  common  in  new  mining  operations  to  experience  unexpected  problems  and  delays  during  development,  construction  and  mine  start-up.  In  addition,  delays  in  the
commencement of mineral production often occur. Accordingly, there are no assurances that our activities will result in profitable mining operations or that mining operations
will be established at any of our properties.

Title risks

Title to mineral properties, as well as the location of boundaries on the ground may be disputed. Moreover, additional amounts may be required to be paid to surface right
owners in connection with any mineral exploration or development activities. At all properties where we have current or planned exploration activities, we believe that we
have either contractual, statutory, or common law rights to make such use of the surface as is reasonably necessary in connection with those activities.

We  do  not  have  title  insurance  for  any  of  our  mining  claims  and  our  ability  to  ensure  that  we  have  obtained  secure  claims  to  individual  mineral  properties  or  mining
concessions  may  be  severely  constrained.  We  have  not  conducted  surveys  of  all  our  claims;  therefore,  the  precise  area  and  location  of  such  claims  may  be  in  doubt.  In
addition,  many  of  our  mineral  properties  have  had  previous  owners,  and  third  parties  may  have  valid  claims  (known  or  unknown)  underlying  our  interests  therein.
Accordingly, our properties may be subject to prior unregistered liens, agreements, royalties, transfers or claims, including First Nations land claims, and title may be affected
by, among other things, undetected defects. In addition, we may be unable to explore our properties as permitted or to enforce our rights with respect to our properties. An
impairment to or defect in our title to our properties could have a material adverse effect on our business, financial condition or results of operation.

94

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Mineral reserves/mineral resources

The  properties  in  which  we  hold  an  interest  are  currently  considered  to  be  in  the  early  exploration  stage  only  and  do  not  contain  a  known  body  of  commercial  minerals
beyond the PFS level. Mineral Resources and Mineral Reserves are, in large part, estimates and no assurance can be given that the anticipated tonnages and grades will be
achieved or that the particular level of recovery will be realized.

Mineral Resources on our properties have been determined based upon assumed cut-off grades, metal prices and operating costs at the time of calculation, as set out in the
applicable technical reports. Future production, if any, could differ dramatically from Mineral Resource and Mineral Reserve estimates because, among other reasons:

● mineralization or formations could be different from those predicted by drilling, sampling and similar examinations;
● calculation errors could be made in estimating Mineral Resources and Mineral Reserves;
● increases in operating mining costs and processing costs could adversely affect Mineral Resources and Mineral Reserves;
● the grade of the Mineral Resources and Mineral Reserves may vary significantly from time to time and there is no assurance that any particular level of metals may

be recovered from the ore; and

● declines in the market price of the metals may render the mining of some or all of the Mineral Reserves uneconomic.

Estimated Mineral Resources may require downward revisions based on changes in metal prices, further exploration or development activity, increased production costs or
actual  production  experience.  This  could  materially  and  adversely  affect  estimates  of  the  tonnage  or  grade  of  mineralization,  estimated  recovery  rates  or  other  important
factors that influence Mineral Resource and Mineral Reserve estimates.

Any  reduction  in  estimated  Mineral  Resources  as  a  result  could  require  material  write  downs  in  investment  in  the  affected  mining  property  and  increased  amortization,
reclamation and closure charges, which could have a material and adverse effect on future cash flows for the property and on our earnings, results of operations and financial
condition.

Because we do not currently have any producing properties, mineralization estimates for our properties may require adjustments or downward revisions based upon further
exploration or development work or actual future production experience. In addition, the grade of mineralized material ultimately mined, if any, may differ from that indicated
by  drilling  results.  There  can  be  no  assurance  that  minerals  recovered  in  small-scale  tests  will  be  duplicated  in  large-scale  tests  under  on-  site  conditions  or  in  production
scale.

Extended declines in market prices for gold or other metals may render portions of our mineralization uneconomic and result in reduced reported mineralization. Any material
reductions in mineralization estimates, or of the ability to extract mineralized material from our properties, could (directly or indirectly) have a material adverse effect on our
results of operations or financial condition.

95

 
 
 
 
 
 
 
 
 
 
 
Capital costs, operating costs, production and economic returns

Actual capital costs, operating costs, production and economic returns with respect to our properties may differ significantly from those we have anticipated and there are no
assurances that any future development activities will result in profitable mining operations. The capital costs required to develop or take our projects into production may be
significantly higher than anticipated. To the extent that such risks impact upon any such properties, there may be a material adverse effect on results of operations on such
properties which may in turn have a material adverse effect on our financial condition.

None of our mineral properties have sufficient operating history upon which we can base estimates of future operating costs. Decisions about the development of these and
other mineral properties will ultimately be based upon feasibility studies. Feasibility studies derive estimates of cash operating costs based upon, among other things:

● anticipated tonnage, grades and metallurgical characteristics of the mineralized material to be mined and processed;

● anticipated recovery rates metals from the mineralized material;

● cash operating costs of comparable facilities and equipment; and

● anticipated climatic conditions.

Cash  operating  costs,  production  and  economic  returns,  and  other  estimates  contained  in  studies  or  estimates  prepared  by  or  for  us,  may  differ  significantly  from  those
anticipated  by  our  current  studies  and  estimates  due  to  a  variety  of  factors,  including  the  impact  of  the  COVID-19  crisis,  and  there  can  be  no  assurance  that  our  actual
operating costs will not be higher than currently anticipated.

Property interests

The  agreements  pursuant  to  which  we  hold  rights  to  certain  of  our  properties  provide  that  we  must  make  a  series  of  cash  payments  over  certain  time  periods  or  make
minimum exploration expenditures. If we fail to make such payments or expenditures in a timely manner, we may lose some or all of our interest in those projects.

Availability of supplies

As with other mineral exploration companies, certain raw materials, supplies and other critical resources used in connection with our operations are obtained from a sole or
limited group of suppliers. Due to an increase in activity in the global mining sector, there has been an increase in global demand for such resources. In addition, the COVID-
19  outbreak  may  cause  disruptions  in  global  supply  chains  which  may  reduce  or  eliminate  the  availability  of  certain  supplies,  particularly  those  sourced  from  outside  of
Canada.  Any  decrease  in  the  supplier’s  inventory  could  cause  unanticipated  cost  increases,  an  inability  to  obtain  adequate  supplies  and  delays  in  delivery  times,  thereby
impacting operating costs, and timing of exploration and development programs.

96

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Lack of infrastructure

The  completion  of  the  development  of  our  development  projects  is  subject  to  various  requirements,  including  the  availability  and  timing  of  acceptable  arrangements  for
electricity or other sources of power, water and transportation facilities. The lack of availability on acceptable terms or the delay in the availability of any one or more of these
items could prevent or delay the development of our exploration projects. If adequate infrastructure is not available in a timely manner, there can be no assurance that: the
development of our projects will be completed on a timely basis, if at all; any resulting operations will achieve the anticipated production volume; or the ongoing operating
costs associated with the development of our projects will not be higher than anticipated.

Personnel recruitment and retention

The  success  of  our  operations  and  development  projects  depend  in  part  on  our  ability  to  attract  and  retain  geologists,  engineers,  metallurgists  and  other  personnel  with
specialized skill and knowledge about the mining industry in the geographic areas in which we operate. The number of persons skilled in exploration and development of
mining  properties  is  limited  and  competition  for  such  persons  is  intense.  As  our  business  grows,  we  may  require  additional  key  financial,  administrative,  and  mining
personnel as well as additional operations staff. There can be no assurance that we will be successful in attracting, training, and retaining qualified personnel as competition
for persons with these skill sets increases. Due to travel restrictions as a result of the COVID-19 crisis we may be unable to source additional personnel from outside the local
area, which may greatly reduce the number of potential qualified candidates for key positions. If we are unable to attract and retain sufficiently trained, skilled or experienced
personnel, our business may suffer and we may experience significantly higher staff or contractor costs, which could have a material adverse effect on our operations and
financial condition.

Financial risks

Substantial capital requirements

Our management team anticipates that we may make substantial capital expenditures for the exploration and development of our properties, in the future. As we are in the
exploration stage with no revenue being generated from the exploration activities on our mineral properties, we have limited ability to raise the capital necessary to undertake
or  complete  future  exploration  work,  including  drilling  programs.  As  of  the  date  of  this  AIF,  financial  markets  have  suffered  significant  disruption  due  to  the  COVID-19
crisis. There can be no assurance that debt or equity financing will be available or sufficient to meet these requirements or for other corporate purposes or, if debt or equity
financing is available, that it will be on terms acceptable to us and any such financing may result in substantial dilution to existing shareholders. Moreover, future activities
may  require  us  to  alter  our  capitalization  significantly.  Our  inability  to  access  sufficient  capital  for  our  operations  could  have  a  material  adverse  effect  on  our  financial
condition, results of operations or prospects. In particular, failure to obtain such financing on a timely basis could cause us to forfeit our interest in certain properties, miss
certain acquisition opportunities and reduce or terminate our operations.

97

 
 
 
 
 
 
 
 
 
 
History of net losses

We have received no revenue to date from activities on our properties, and there is no assurance that any of our properties will generate earnings, operate profitably or provide
a  return  on  investment  in  the  future.  We  have  not  determined  that  production  activity  is  warranted  as  of  yet  on  any  of  our  mineral  properties.  Even  if  we  (alone  or  in
conjunction with a third party) undertake development and production activities on any of our mineral properties, there is no certainty that we will produce revenue, operate
profitably or provide a return on investment in the future.

We are subject to all of the risks associated with new mining operations and business enterprises including, but not limited to:

● the timing and cost, which can be considerable, for the further construction of mining and processing facilities;

● the availability and costs of skilled labour, consultants, mining equipment and supplies;

● the availability and cost of appropriate smelting and/or refining arrangements;

● the need to obtain necessary environmental and other governmental approvals, licenses and permits, and the timing of those approvals, licenses and permits; and

● the availability of funds to finance construction and development activities.

It is common in new mining operations to experience unexpected problems and delays during construction, development, and mine start-up. In addition, delays in mineral
production often occur. Accordingly, there are no assurances that our activities will result in sustainable profitable mining operations or that we will successfully establish
mining operations or profitably produce metals at any of our other properties.

Potential volatility of share price

The securities markets in Canada have in the past experienced a high level of price and volume volatility, and the market price of securities of many junior companies have
experienced wide fluctuations in price. The market price of our shares may be volatile and could be subject to wide fluctuations due to a number of factors, including but not
limited to: actual or anticipated fluctuations in the results of our operations; changes in estimates of our future results of operations by management or securities analysts; and
general economic or industry changes. In addition, the financial markets are currently experiencing significant price and value fluctuations as a result of the COVID-19 crisis
that have particularly affected the market prices of equity securities of many venture issuers and that sometimes have been unrelated to the operating performance of these
companies. Broad market fluctuations, as well as economic conditions generally and in the mining industry specifically, may adversely affect the market price of our shares.

Non-Canadian investors

We  are  a  public  Canadian  corporation,  with  our  principal  place  of  business  in  Canada.  A  majority  of  our  directors  and  officers  are  residents  of  Canada  and  a  significant
portion  of  our  assets  and  the  assets  of  a  majority  of  our  directors  and  officers  are  located  outside  the  United  States.  Consequently,  it  may  be  difficult  for  US  or  foreign
investors to effect service of process within their local jurisdiction upon First Mining or its directors or officers or such experts who are residents of Canada, or to realize in
their local jurisdiction upon judgments of local courts (including, but not limited to, judgments predicated upon civil liabilities under the United States Securities Act of 1933,
as  amended).  Investors  should  not  assume  that  Canadian  courts:  (i)  would  enforce  judgments  of  foreign  courts  obtained  in  actions  against  First  Mining  or  such  directors,
officers or experts (including, but not limited to, judgments predicated upon the civil liability provisions of the US federal securities laws or the securities or “blue sky” laws
of any state within the United States); or (ii) would enforce, in original actions, liabilities against First Mining or such directors, officers or experts predicated upon foreign
securities  laws  (including,  but  not  limited  to,  the  US  federal  securities  laws  or  any  state  securities  or  “blue  sky”  laws).  In  addition,  the  protections  afforded  by  Canadian
securities laws may not be available to foreign investors.

98

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Volatility of mineral prices

Metal prices are affected by numerous factors beyond our control, such as industrial demand, inflation and expectations with respect to the rate of inflation, the strength of the
US dollar and of other currencies, interest rates, forward sales by producers, production and cost levels, changes in investment trends, global and regional levels of supply and
demand,  metal  stock  levels  maintained  by  producers,  inventory  carrying  costs,  availability,  demand  and  costs  of  metal  substitutes,  international  economic  and  political
conditions,  reduced  demand  resulting  from  obsolescence  of  technologies  and  processes  utilizing  metals  and  increased  production  due  to  new  mine  developments  and
improved mining and production levels. Gold prices are sometimes subject to rapid short-term changes because of speculative activities, and the market price of gold and
other metals may not remain at current levels. If these prices were to decline significantly or for an extended period of time, we might be unable to continue our operations,
develop our properties or fulfill our obligations under agreements with our partners or under our permits and licenses. As a result, we might lose our interest in, or be forced
to  sell,  some  of  our  properties.  In  the  event  of  a  sustained,  significant  drop  in  gold  prices,  we  may  be  required  to  re-evaluate  our  assets,  resulting  in  reduced  estimates  of
Mineral Resources and Mineral Reserves and in material write-downs of our investment in mining properties. Furthermore, since gold prices are established in US dollars, a
significant decrease in the value of the Canadian dollar relative to the US dollar coupled with stable or declining gold prices could adversely affect our results with respect to
development of and eventual sale of gold.

Global financial conditions

Global  financial  conditions  have,  at  various  times  in  the  past  and  may,  in  the  future,  experience  extreme  volatility.  Many  industries,  including  the  mining  industry,  are
impacted by volatile market conditions. Global financial conditions may be subject to sudden and rapid destabilizations in response to economic shocks or other events, such
as  the  evolving  situation  concerning  the  COVID-19  pandemic.  A  slowdown  in  the  financial  markets  or  other  economic  conditions,  including  but  not  limited  to  consumer
spending,  employment  rates,  business  conditions,  inflation,  fluctuations  in  fuel  and  energy  costs,  consumer  debt  levels,  lack  of  available  credit,  the  state  of  the  financial
markets, interest rates and tax rates, may adversely affect our growth and financial condition. Future economic shocks may be precipitated by a number of causes, including
government debt levels, fluctuations in the price of oil and other commodities, the volatility of metal prices, geopolitical instability, changes in laws or governments, war,
terrorism, the volatility of currency exchanges, inflation or deflation, the devaluation and volatility of global stock markets, pandemics and natural disasters. Any sudden or
rapid destabilization of global economic conditions could impact our ability to obtain equity or debt financing in the future on terms favourable to us or at all. In such an
event, our operations and financial condition could be adversely impacted.

Public Health Crises

Our business, operations and financial condition could be materially adversely affected by the outbreak of epidemics, pandemics or other health crises, such as COVID-19,
and by reactions by government and private actors to such outbreaks. As at the date of this AIF, the global reactions to the spread of COVID-19 have led to, among other
things,  significant  restrictions  on  travel,  quarantines,  temporary  business  closures  and  a  general  reduction  in  consumer  activity.  While  these  effects  are  expected  to  be
temporary, the duration of the disruptions to business internationally and the related financial impact cannot be estimated with any degree of certainty at this time. Such public
health  crises  can  result  in  disruptions  and  extreme  volatility  in  financial  markets  and  global  supply  chains  as  well  as  declining  trade  and  market  sentiment  and  reduced
mobility of people, all of which could impact commodity prices, interest rates, credit ratings, credit risk, availability of financing and inflation. The risks to the Company of
such public health crises also include risks to employee health and safety and may result in a slowdown or temporary suspension of operations at some or all of our mineral
properties  as  well  as  our  head  office. Although  we  are  currently  continuing  certain  head  office  and  administrative  functions  remotely,  many  other  functions,  including  the
conduct  of  exploration  and  development  programs,  cannot  be  conducted  remotely  and  may  be  impacted  or  delayed  if  we  experience  additional  limitations  on  employee
mobility.

99

 
 
 
 
 
 
 
 
 
As of the date of this AIF, the province of Ontario is currently subject to a number of emergency orders (the “Emergency Orders”) resulting from COVID-19 which impose
various restrictions on workplaces in the province. Our exploration properties in Ontario are at present not directly affected by the Emergency Orders. However, there can be
no guarantee that they will not be in the future or that governments in other provinces in which we have mineral properties will not pass orders reducing or preventing access
to our properties. Any such orders may have a material adverse effect upon ongoing exploration programs at our properties and, ultimately, on our business and financial
condition. At this point, the extent to which COVID-19 may impact us remains uncertain; however, it is possible that COVID-19 could have a material adverse effect on our
business, results of operations and financial condition.

Dividends

To  date,  we  have  not  paid  any  dividends  on  our  outstanding  common  shares  and  we  have  no  plans  to  declare  or  pay  dividends  in  the  near  future.  Any  decision  to  pay
dividends on our shares will be made by our Board on the basis of our earnings, financial requirements and other conditions.

Dilution

The number of common shares we are authorized to issue is unlimited. We may, in our sole discretion, issue additional common shares from time to time, and the interests of
the shareholders may be diluted thereby.

Political risks

Indigenous peoples

Various international and national laws, codes, court decisions, resolutions, conventions, guidelines, and other materials (collectively, the “Instruments”) relate to the rights
of Indigenous peoples, including the First Nations and Metis of Canada. We operate in some areas presently or previously inhabited or used by Indigenous peoples including
areas  in  Canada  over  which  Indigenous  peoples  have  established  or  asserted  Aboriginal  treaty  rights,  Aboriginal  title,  or  Aboriginal  rights.  Many  of  these  rights  or  titles
impose obligations on governments and private parties as they relate to the rights of Indigenous people concerning resource development. Some mandate that government
consult  with,  and  if  required,  accommodate  Indigenous  people  for  government  actions  which  may  affect  Indigenous  people,  including  actions  to  approve  or  grant  mining
rights  or  exploration,  development  or  production  permits.  The  obligations  of  government  and  private  parties  under  the  various  international  and  national  Instruments
pertaining to Indigenous people continue to evolve and be defined.

Government  policy  and  its  implementation  regarding  Indigenous  consultation  (including  the  requirements  that  are  imposed  on  the  mining  industry)  and  accommodation
continue  to  change.  In  certain  circumstances,  Indigenous  communities  are  entitled  to  be  consulted  prior  to,  and  during,  resource  development.  The  consultation  and
accommodation process and expectations of parties (government, Indigenous communities and industry proponents) involved can vary considerably from project to project,
within stages of the project life and among Indigenous communities. There can be overlapping or inconsistent Indigenous or treaty claims respecting a project. These can
contribute to process uncertainty, increased costs, delay in receiving required approvals, and potentially, an inability to secure the required approvals for a project, each of
which  could  have  a  material  adverse  effect  on  the  Company’s  business,  operations,  results  of  operations,  financial  condition  and  future  prospects.  In  addition,  the  federal
government has committed to introducing legislation to implement the United Nations Declaration on the Rights of Indigenous Peoples (“UNDRIP”). Some provinces and
territories are also considering, or have introduced similar legislation. It is uncertain how the federal and other governments intend to implement UNDRIP. Implementation
may  add  additional  uncertainty  as  to  the  nature  and  extent  of  Aboriginal  rights  or  title  and  may  also  include  new  processes  and  additional  consultation  requirements  for
project development and operations, which may increase costs, increase approval timelines and impose development and operational additional obligations or restrictions.

100

 
 
 
 
 
 
 
 
 
 
 
 
Our  current  operations  and  current  and  future  exploration  program  may  be  subject  to  a  risk  that  one  or  more  groups  of  Indigenous  people  may  oppose  the  operations  on
development of any of our properties or on properties in which we hold a direct or indirect interest, even where we have entered into agreements with applicable Indigenous
and non-Indigenous authorities. Such opposition may be directed through legal or administrative proceedings or expressed in manifestations such as protests, roadblocks or
other  forms  of  public  expression  against  our  activities.  Opposition  by  Indigenous  people  to  our  operations  may  require  modification  of  or  preclude  development  of  our
projects or may require us to enter into agreements with Indigenous people with respect to projects on such properties. Such agreements or restrictions on operations may
have a material adverse effect on our business, financial condition and results of operations. Even where such agreements have been entered into, there can be no certainty
that there will not be disagreements between the Company and groups or sub-groups of Indigenous persons which may result in project delays or have other material adverse
effects on the Company.

Regulatory risks

Government approvals

Our activities are subject to government approvals, various laws governing prospecting, development, land resumptions, production taxes, labour standards and occupational
health, mine safety, toxic substances and other matters, including issues affecting local First Nations populations. The costs associated with compliance with these laws and
regulations can be substantial. Although we believe our activities are carried out in accordance with all applicable rules and regulations, no assurance can be given that new
rules and regulations will not be enacted or that existing rules and regulations will not be applied in a manner which could limit or curtail production or development, or cause
additional expense, capital expenditures, restrictions or delays in the development of our properties. Amendments to current laws and regulations governing operations and
activities of exploration and mining, or more stringent implementation thereof, could have a material adverse impact on our business, operations and financial performance.
Further, the mining licenses and permits issued in respect of our projects may be subject to conditions which, if not satisfied, may lead to the revocation of such licenses. In
the event of revocation, the value of our investments in such projects may decline.

Mineral claims, licenses and permitting

Our mineral claims, licenses and permits are subject to periodic renewal and may only be renewed a limited number of times for a limited period of time. While we anticipate
that renewals will be given as and when sought, there is no assurance that such renewals will be given as a matter of course and there is no assurance that new conditions will
not be imposed in connection therewith. Our business objectives may also be impeded by the costs of holding and/or renewing the mineral claims, licenses and permits. In
addition, the duration and success of efforts to obtain and renew mineral claims, licenses and permits are contingent upon many variables not within our control.

Our current and anticipated future operations, including further exploration, development activities and commencement of production on our properties, require licenses and
permits from various governmental authorities. Our business requires many environmental, construction and mining permits, each of which can be time-consuming and costly
to  obtain,  maintain  and  renew.  In  connection  with  our  current  and  future  operations,  we  must  obtain  and  maintain  a  number  of  permits  that  impose  strict  conditions,
requirements and obligations on the Company, including those relating to various environmental and health and safety matters. To obtain, maintain and renew certain permits,
we are required to conduct environmental assessments pertaining to the potential impact of our operations on the environment and to take steps to avoid or mitigate those
impacts. We cannot be certain that all licenses and permits that we may require for our operations will be obtainable on reasonable terms or at all. Delays or a failure to obtain
such licenses and permits, or a failure to comply with the terms of any such licenses and permits that we have obtained, could have a material adverse impact on First Mining.

101

 
 
 
 
 
 
 
 
 
 
On  August  28,  2019,  the  Impact  Assessment  Act  came  into  force  and  replaced  the  Canadian  Environmental  Assessment  Act,  thereby  establishing  a  new  environmental
assessment  process.  It  is  uncertain  how  the  new  assessment  process  adopted  by  the  federal  government  will  result  in  a  more  efficient  approval  process.  The  Impact
Assessment Act broadens the assessment factors to include health, economy, social, gender, and sustainability considerations. The lack of regulatory certainty is likely to have
an influence on investment decisions for major projects. Even when projects are approved on a federal level, such projects often face further delays due to interference by
provincial and municipal governments, as well as court challenges related to issues such as Indigenous rights, the government's duty to consult and accommodate Indigenous
peoples and the sufficiency of the relevant environmental review processes. Such political and legal opposition creates further uncertainty.

Anti-bribery legislation

Our activities are subject to a number of laws that prohibit various forms of corruption, including domestic laws, that prohibit both commercial and official bribery and anti-
bribery  laws  that  have  a  global  reach  such  as  the  Corruption  of  Foreign  Public  Officials Act.  The  increasing  number  and  severity  of  enforcement  actions  in  recent  years
present  particular  risks  with  respect  to  our  business  activities,  to  the  degree  that  any  employee  or  other  person  acting  on  our  behalf  might  offer,  authorize,  or  make  an
improper payment to a government official, party official, candidate for political office, or political party, an employee of a state-owned or state-controlled enterprise, or an
employee of a public international organization.

Transparency in the extractive industry

The Canadian Extractive Sector Transparency Measures Act (“ESTMA”) came into force on June 1, 2015 and applies to fiscal periods which commenced after that date. As
a result, as a Canadian publicly listed corporation we must report annually on payments of $100,000 or more made to any level of government in Canada or abroad related to
a  single  project.  The  reporting  applies  to  taxes,  licences,  fees,  royalties,  production  entitlements,  bonuses,  dividends,  fines  and  infrastructure  payments.  Our  reports  under
ESTMA are publicly available on the Department of Natural Resources website (www.nrcan.gc.ca).

Environmental risks

Environmental laws and regulations

All phases of the mining business present environmental risks and hazards and are subject to environmental regulation pursuant to a variety of international conventions and
state and municipal laws and regulations. Environmental legislation provides for, among other things, restrictions, conditions and prohibitions on, amongst other things, spills,
releases or emissions of various substances produced in association with mining operations and development. The legislation also requires that mines and exploration sites be
operated, maintained, abandoned and reclaimed to the satisfaction of applicable regulatory authorities and may require the deposit of adequate reclamation and remediation
security.  Compliance  with  such  legislation  can  require  significant  expenditures  and  a  breach  may  result  in  the  imposition  of  fines  and  penalties,  some  of  which  may  be
material. Environmental legislation is evolving in a manner expected to result in stricter standards and enforcement, larger fines and liability and potentially increased capital
expenditures  and  operating  costs.  Environmental  assessments  of  proposed  projects  carry  a  heightened  degree  of  responsibility  for  companies  and  directors,  officers  and
employees.  Companies  engaged  in  exploration  and  development  of  mineral  properties  may  from  time  to  time  experience  increased  costs  and  delays  in  exploration  and
production as a result of the need to comply with applicable laws, regulations and permits. The cost of compliance with changes in governmental regulations has a potential to
reduce the profitability of operations.

102

 
 
 
 
 
 
 
 
 
 
 
We believe we are in substantial compliance with all material laws and regulations which currently apply to our activities. We cannot give any assurance that, notwithstanding
our precautions and limited history of activities, breaches of environmental laws (whether inadvertent or not) or environmental pollution will not result in additional costs or
curtailment  of  planned  activities  and  investments,  which  could  have  a  material  and  adverse  effect  on  our  future  cash  flows,  earnings,  results  of  operations  and  financial
condition.  Failure  to  comply  with  applicable  laws,  regulations,  and  permitting  requirements  may  result  in  enforcement  actions  thereunder,  including  orders  issued  by
regulatory  or  judicial  authorities  causing  operations  to  cease  or  be  curtailed,  and  may  include  corrective  measures  requiring  capital  expenditures,  installation  of  additional
equipment, or remedial actions. Companies engaged in mining operations may be required to compensate those suffering loss or damage by reason of the mining activities
and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations and, in particular, environmental laws even where there has been no
intentional wrong-doing.

Amendments  to  current  laws,  regulations  and  permits  governing  operations  and  activities  of  mining  companies,  or  more  stringent  implementation  thereof,  could  have  a
material adverse impact on us and cause increases in capital expenditures or any future production costs or require abandonment or delays in the development of new mining
properties.

Compliance with emerging climate change regulations

Climate change is an international concern and poses risks to issuers of both direct and indirect effects of physical climate changes and government policy including climate
change legislation and treaties. Both types of risks could result in increased costs, and therefore decreased profitability of our operations. Governments at all levels may be
moving  towards  enacting  legislation  to  address  climate  change  concerns,  such  as  requirements  to  reduce  emission  levels  and  increase  energy  efficiency,  and  political  and
economic events may significantly affect the scope and timing of climate change measures that are ultimately put in place. Where legislation has already been enacted, such
regulations may become more stringent, which may result in increased costs of compliance. There is no assurance that compliance with such regulations will not have an
adverse effect on our results of operations and financial condition. Furthermore, given the evolving nature of the debate related to climate change and resulting requirements,
it is not possible to predict the impact on our results of operations and financial condition.

Climate change may result in a number of physical impacts on our business, including an increasing frequency of extreme weather events (such as increased periods of snow
and increased frequency and intensity of storms), water shortages and extreme temperatures, which have the potential to disrupt our exploration and development plans and
may have other impacts on our business, including transportation difficulties and supply disruptions. Our emergency plans for managing extreme weather conditions may not
be sufficient and extended disruptions could have adverse effects on our results of operations and financial condition.

Industry risks

Speculative nature of mineral development activities

Resource exploration and development is a speculative business, characterized by a number of significant risks including, among other things, unprofitable efforts resulting
not only from the failure to discover mineral deposits but from finding mineral deposits which, though present, may, for a variety of factors not be economic to produce.

103

 
 
 
 
 
 
 
 
 
 
 
The marketability of minerals acquired or discovered by us may be affected by numerous factors which are beyond our control and which cannot be accurately predicted, such
as:

● market fluctuations;

● the proximity and capacity of milling facilities;

● mineral markets;

● processing equipment; and

● government regulations, including regulations relating to royalties, allowable production, importing and exporting of minerals and environmental protection.

Estimates of Mineral Resources, Mineral Reserves, mineral deposits and production costs can also be affected by such factors as:

● environmental permitting regulations and requirements;

● weather;

● environmental factors;

● unforeseen technical difficulties;

● unusual or unexpected geological formations; and

● work interruptions.

In addition, the grade of mineralized material ultimately mined may differ from that indicated by drilling results.

Short term factors relating to mineral properties, such as the need for orderly development of mineralized bodies or the processing of new or different grades, may also have
an  adverse  effect  on  mining  operations  and  on  the  results  of  operations.  Material  changes  in  Mineral  Reserves,  grades,  stripping  ratios  or  recovery  rates  may  affect  the
economic viability of any project.

Our  mineral  properties  are  all  in  the  exploration  stage  only  and  are  without  known  bodies  of  commercial  mineralized  material.  Few  properties  which  are  explored  are
ultimately  developed  into  producing  mines.  Major  expenses  may  be  required  to  establish  Mineral  Reserves,  develop  metallurgical  processes  and  construct  mining  and
processing facilities at a particular site. There is no assurance that our mineral exploration activities will result in any discoveries of new commercial bodies of mineralized
material. There are no reassurances that commercial production activities will commence on any of our properties.

104

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Competition

The mining industry is highly competitive. We compete with companies for the acquisition, exploration and development of gold and other precious and base metals, and for
capital to finance such activities, and such companies may have similar or greater financial, technical and personnel resources available to them.

Other risks

Reliance on key employees

We manage our business with a number of key personnel, including key contractors, the temporary or permanent loss or unavailability (including as a result of exposure to or
quarantine as a result of COVID-19) of a number of whom could have a material adverse effect on us. In addition, as our business develops and expands, we believe that our
future success will depend greatly on our continued ability to attract and retain highly-skilled and qualified personnel and contractors. In assessing the risk of an investment in
our  shares,  potential  investors  should  realize  that  they  are  relying  on  the  experience,  judgment,  discretion,  integrity  and  good  faith  of  our  management  team  and  board  of
directors. We cannot be certain that key personnel will continue to be employed by us or that we will be able to attract and retain qualified personnel and contractors in the
future.  Failure  to  retain  or  attract  key  personnel  could  have  a  material  adverse  effect  on  us.  We  do  not  maintain  “key  person”  insurance  policies  in  respect  of  our  key
personnel.

Conflicts of interest

Certain directors and officers will be engaged in, and will continue to engage in, other business activities on their own behalf and on behalf of other companies (including
mineral companies) and, as a result of these and other activities, such directors and officers may become subject to conflicts of interest. The BCBCA provides that if a director
has a material interest in a contract or proposed contract or agreement that is material to the issuer, the director must disclose his interest in such contract or agreement and
must refrain from voting on any matter in respect of such contract or agreement, subject to and in accordance with the BCBCA. To the extent that conflicts of interest arise,
such conflicts will be resolved in accordance with the provisions of the BCBCA and in accordance with our Code of Business Conduct and Ethics. As a result of a conflict of
interest, we may miss the opportunity to participate in certain transactions, which may have a material adverse effect on our financial position.

Uninsured risks

Our business is subject to a number of risks and hazards, including adverse environmental conditions, industrial accidents, labour disputes, unusual or unexpected geological
conditions, ground or slope failures, cave-ins, changes in the regulatory environment and natural phenomena, such as inclement weather conditions, floods and earthquakes.
Such occurrences could result in damage to our properties, personal injury or death, delays in program development, monetary losses and possible legal liability.

Despite  efforts  to  attract  and  retain  qualified  personnel,  as  well  as  the  retention  of  qualified  consultants,  to  manage  our  interests,  even  when  those  efforts  are  successful,
people are fallible and human error and mistakes could result in significant uninsured losses to us. These could include, but are not limited to, loss or forfeiture of mineral
claims or other assets for non‐payment of fees or taxes, erroneous or incomplete filings or non‐fulfillment of other obligations, significant tax liabilities in connection with
any  tax  planning  effort  we  might  undertake  or  mistakes  in  interpretation  and  implementation  of  tax  laws  and  practices,  and  legal  claims  for  errors  or  mistakes  by  our
personnel.

105

 
 
 
 
 
 
 
 
 
 
 
 
 
Although we maintain insurance to protect against certain risks in amounts that we consider reasonable, our insurance will not cover all the potential risks associated with our
operations. We may also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage may not continue to be available or may
not  be  adequate  to  cover  any  resulting  liability.  Moreover,  insurance  against  certain  risks,  such  as  environmental  pollution  or  other  hazards  as  a  result  of  exploration  and
production,  is  not  generally  available  to  us  or  to  other  mineral  exploration  companies  on  acceptable  terms.  We  may  also  become  subject  to  liability  for  pollution  or  other
hazards which may not be insured against or which we may elect not to insure against because of premium costs or other reasons. Losses from these events may cause us to
incur significant costs that could have a material adverse effect upon our financial performance, results of operations and business outlook.

Litigation and regulatory proceedings

We may be subject to civil claims (including class action claims) based on allegations of negligence, breach of statutory duty, public nuisance or private nuisance or otherwise
in connection with our operations, or investigations relating thereto. While we are presently unable to quantify any potential liability under any of the above heads of damage,
such liability may be material to us and may materially adversely affect our ability to continue operations. In addition, we may be subject to actions or related investigations
by governmental or regulatory authorities in connection with our business activities, including, but not limited to, current and historic activities at our mineral properties. Such
actions may include prosecution for breach of relevant legislation or failure to comply with the terms of our licenses and permits and may result in liability for pollution, other
fines or penalties, revocations of consents, permits, approvals or licenses or similar actions, which could be material and may impact the results of our operations. Our current
insurance coverage may not be adequate to cover any or all the potential losses, liabilities and damages that could result from the civil and/or regulatory actions referred to
above.

Future Acquisitions and Dispositions

As part of our business strategy, we have sought and may continue to seek new mining and exploration opportunities in the mining industry. In pursuit of such opportunities,
we may fail to select appropriate acquisition targets or negotiate acceptable arrangements, including arrangements to finance acquisitions or integrate the acquired businesses
into us. Ultimately, any acquisitions would be accompanied by risks, which could include:

● a significant change in commodity prices after we have committed to complete the transaction and established the purchase price or exchange ratio;

● a material ore body could prove to be below expectations;

● difficulty in integrating and assimilating the operations and workforce of any acquired companies;

● realizing anticipated synergies and maximizing the financial and strategic position of the combined enterprise;

● the bankruptcy of parties with whom we have arrangements;

106

 
 
 
 
 
 
 
 
 
 
 
 
 
● maintaining uniform standards, policies and controls across the organization;

● disruption of our ongoing business and its relationships with employees, suppliers, contractors and other stakeholders as we integrate the acquired business or assets;

● the acquired business or assets may have unknown liabilities which may be significant;

● delays as a result of regulatory approvals; and

● exposure to litigation (including actions commenced by shareholders) in connection with the transaction.

Any material issues that we encounter in connection with an acquisition could have a material adverse effect on our business, results of operations and financial position.

Joint ventures

Our business plan anticipates that we may retain interest in properties which we have transferred in whole or in part to other parties who may choose to establish mining
operations, and that interest may be in the form of a joint venture or earn-in arrangement, such as the Earn-In Agreement entered into in relation to the Pickle Crow Project.
The existence or occurrence of one or more of the following circumstances and events could have a material adverse impact on our profitability or the viability of our interests
that  may  be  held  through  joint  venture  arrangements,  including  the  Pickle  Crow  Project,  which  could  have  a  material  adverse  impact  on  our  future  cash  flows,  earnings,
results of operations and financial condition:

● disagreements with joint venture partners on how to develop and operate mines efficiently;

● inability to exert influence over certain strategic decisions made in respect of joint venture properties;

● inability of joint venture partners to meet their obligations to the joint venture or third parties; and

● litigation between joint venture partners regarding joint venture matters.

We do not intend to be the operator of the Pickle Crow Project and therefore the success of any operations will be dependent on our joint venture partner (who will act as
operator). We are subject to the decisions made by the operator in the operation of the Pickle Crow Project and we will have to rely on the operator for accurate information
about  the  project.  Failure  by  the  operator  to  prudently  manage  the  operations  of  the  Pickle  Crow  Project  could  have  a  material  adverse  effect  on  our  business,  results  of
operations and financial position.

107

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Future Sales of Shares

Sales of a substantial number of our shares in the public market could occur at any time following, or in connection with, the completion of any offering. These sales, or the
market perception that the holders of a large number of our shareholders intend to sell our shares, could reduce the market price of our shares. A decline in the market price of
the shares could impair our ability to raise additional capital through the sale of securities should we desire to do so.

The issuance of shares to shareholders whose investment profile may not be consistent with our business may lead to significant sales of our shares or a perception that such
sales may occur, either of which could have a material adverse effect on the market for and market price of our shares. We are unable to predict the effect that sales may have
on the then prevailing market price of our shares.

Reputation Loss

Reputation  loss  may  result  in  decreased  investor  confidence,  increased  challenges  in  developing  and  maintaining  community  relations  and  an  impediment  to  our  overall
ability to advance our projects, thereby having a material adverse impact on our financial performance, financial condition and growth prospects. Damage to our reputation
can  be  the  result  of  the  actual  or  perceived  occurrence  of  any  number  of  events,  and  could  include  any  negative  publicity  (for  example,  with  respect  to  our  handling  of
environmental matters or our dealings with community groups), whether true or not. The increased usage of social media and other web-based tools used to generate, publish
and discuss user-generated content and to connect with other users has made it increasingly easier for individuals and groups to communicate and share opinions and views in
regards to us and our activities, whether true or not. We do not ultimately have direct control over how we are perceived by others and reputational loss could have a material
adverse impact on our financial performance, financial condition and growth prospects.

Equity Price Risk

The Company is exposed to equity price risk as a result of holding equity investments, which comprise of marketable securities and mineral property investments, in other
mineral property exploration companies.

Foreign Currency Risk

The Company is exposed to the financial risk related to the fluctuation of foreign exchange rates. The Company operates in Canada and the United States, and a portion of the
Company’s expenses are incurred in Canadian dollars and US dollars. A significant change in the currency exchange rates between the Canadian and US currencies could
have an effect on the Company’s results of operations, financial position or cash flows.

Interest Rate Risk

Interest rate risk is the risk that future cash flows will fluctuate as a result of changes in market interest rates. The Company does not have any borrowings that are subject to
fluctuations in market interest rates. Interest rate risk is limited to potential decreases on the interest rate offered on cash and cash equivalents held with chartered Canadian
financial institutions. The Company considers this risk to be immaterial.

108

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Credit Risk

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. Financial instruments
which are potentially subject to credit risk for the Company consist primarily of cash and cash equivalents, accounts and other receivables, and the reclamation deposit. The
Company considers credit risk with respect to its cash and cash equivalents to be immaterial as cash and cash equivalents are mainly held through large Canadian financial
institutions.

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company’s policy is to ensure that it will have sufficient
cash  to  allow  it  to  meet  its  liabilities  when  they  become  due,  under  both  normal  and  stressed  conditions,  without  incurring  unacceptable  losses  or  risking  damage  to  the
Company’s  reputation.  The  Company  manages  its  liquidity  risk  by  preparing  annual  estimates  of  exploration  and  administrative  expenditures  and  monitoring  actual
expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.

Capital Risk Management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to pursue the exploration and retention of its
mineral properties. The Company has historically demonstrated the ability to raise new capital through equity issuances and/or through surplus cash as part of its acquisitions.
In the management of capital, the Company includes the components of shareholders’ equity as well as cash.

Financing Risks

The Company has finite financial resources, has no current source of operating cash flow and has no assurance that additional funding will be available to it for its future
activities, including exploration or development of mineral projects. Such further activities may be dependent upon the Company’s ability to obtain financing through equity
or debt financing or other means. As a result of the ongoing COVID-19 crisis, global financial markets, and the economy in general, are experiencing extreme volatility which
may  impact  our  ability  to  obtain  financing.  Failure  to  obtain  additional  financing  could  result  in  delay  or  indefinite  postponement  of  exploration  and  development  of  the
Company’s existing mineral projects and could result in the loss of one or more of its properties.

Other risks

Our business and operations are subject to a number of risks and hazards including:

● environmental hazards;

● discharge of pollutants or hazardous chemicals;

● industrial accidents;

● failure of processing and mining equipment;

109

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● labour disputes;

● supply problems and delays (including as a result of public health crises);

● changes in regulatory environment;

● encountering unusual or unexpected geologic formations or other geological or grade problems;

● encountering unanticipated ground or water conditions;

● cave-ins, pit-wall failures, flooding, rock bursts and fire;

● periodic interruptions due to inclement or hazardous weather conditions;

● uncertainties relating to the interpretation of drill results;

● inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses;

● results of initial feasibility, pre-feasibility and feasibility studies, and the possibility that future exploration or development results will not be consistent with our

expectations;

● the potential for delays in exploration or the completion of feasibility studies; and

● other acts of God or unfavourable operating conditions.

Such  risks  could  result  in  damage  to,  or  destruction  of,  properties  or  equipment,  personal  injury  or  death,  loss  of  key  employees,  environmental  damage,  delays  in
development programs, monetary losses and possible legal liability. Satisfying such liabilities may be very costly and could have a material adverse effect on future cash flow,
results of operations and financial condition.

Legal proceedings

There are no material legal proceedings which we are or were a party to or to which our properties are or were subject, either during the financial year ended December 31,
2020 or as of the date of this AIF, nor are we aware that any material proceedings are contemplated.

During  the  financial  year  ended  December  31,  2020,  and  as  of  the  date  of  this  AIF,  we  have  not  had  any  penalties  or  sanctions  imposed  by  a  court  relating  to  securities
legislation or by a securities regulatory authority, or by a court or regulatory body. We have also never been involved in a settlement agreement before a court relating to
securities legislation or with a securities regulatory authority.

Investor information

Share capital

Our authorized share capital consists of:

● an unlimited number of common shares; and

● an unlimited number of preferred shares, issuable in series.

Common shares

We can issue an unlimited number of common shares with no nominal or par value. As of December 31, 2020 and as of the date of this AIF, we had 697,216,453 common
shares and 697,369,936 common shares outstanding, respectively. All of our outstanding common shares are fully paid and non-assessable.

The following is a summary of the principal attributes of our common shares:

Voting rights

Holders of our common shares are entitled to vote on all matters that are to be voted on at any shareholder meeting, other than meetings that are only for holders of another
class  or  series  of  shares.  Each  common  share  you  own  represents  one  vote.  There  are  no  cumulative  voting  rights,  and  directors  do  not  stand  for  re-election  at  staggered
intervals.

Dividends

Holders  of  our  common  shares  are  entitled  to  share  pro rata  in  any  profits  of  First  Mining  to  the  extent  that  such  profits  are  distributed  either  through  the  declaration  of
dividends by our Board or otherwise distributed to shareholders. There are no indentures or agreements limiting the payment of dividends. The Company has not paid any
dividends since incorporation and it has no plans to pay dividends for the foreseeable future.

Rights on dissolution

In the event of the liquidation, dissolution or winding up of First Mining, the holders of our common shares will be entitled to receive, on a pro rata basis, all of our assets
remaining after payment of all of our liabilities.

111

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Pre-emptive, conversion and other rights

Holders of our common shares have no pre-emptive, redemption, purchase or conversion rights attaching to their shares, and our common shares, when fully paid, will not be
liable to further call or assessment. No other class of shares may be created without the approval of the holders of our common shares. There are no provisions discriminating
against any existing or prospective holder of our common shares as a result of such shareholder owning a substantial number of common shares. In addition, non-residents of
Canada who hold our common shares have the same rights as shareholders who are residents of Canada.

Preferred shares

We can issue an unlimited number of preferred shares with no nominal or par value. As of the date of this AIF, we did not have any preferred shares outstanding.

The  preferred  shares  are  issuable  in  series.  The  preferred  shares  of  each  series  rank  in  parity  with  the  preferred  shares  of  every  other  series  with  respect  to  dividends  and
return of capital and are entitled to a preference over the common shares and any other shares ranking junior to the preferred shares with respect to priority in the payment of
dividends and the distribution of assets in the event of the liquidation, dissolution or winding-up of First Mining.

Our Board of Directors is empowered to fix the number of shares and the rights to be attached to the preferred shares of each series, including the amount of dividends and
any conversion, voting and redemption rights. Subject to our articles of incorporation and to applicable law, the preferred shares as a class are not entitled to receive notice of
or attend or vote at meetings of the Company’s shareholders.

Security-based compensation and convertible securities

Security-based compensation

Our shareholders most recently approved the Company’s existing share-based compensation plan (the “Share-Based Compensation Plan”) on June 25, 2019. The maximum
number  of  common  shares  issuable  under  the  Share-Based  Compensation  Plan,  together  with  the  number  of  common  shares  issuable  under  any  other  security-based
compensation arrangement of the Company, shall not in the aggregate exceed 10% of our issued and outstanding common shares.

The  Share-Based  Compensation  Plan  allows  for  the  issuance  of  up  to  10%  of  our  issued  and  outstanding  common  shares  as  incentive  share  options  (“Options”), bonus
shares, restricted share units, performance share units and deferred share units to our directors, officers, employees and consultants.

For a full description of the Share-Based Compensation Plan, see the section entitled “Particulars of the Matters to be Acted Upon – Approval of share-based compensation

Pickle Crow Earn-In Agreement

On March 12, 2020, we entered into the Pickle Crow Earn-In Agreement with Auteco pursuant to which Auteco may earn up to an 80% interest in PC Gold, a wholly-owned
subsidiary of First Mining that owns the Pickle Crow Project. During the term of the Pickle Crow Earn-In Agreement, Auteco will be the operator of the Pickle Crow Project
and will be responsible for all project expenditures.

As  upfront  consideration,  we  received  $50,000  cash  in  January  2020  (as  consideration  for  entering  into  a  term  sheet  as  a  precursor  to  the  definitive  agreement),  and  we
received $50,000 in cash concurrently with the execution of the Pickle Crow Earn-In Agreement. In addition, First Mining received 25,000,000 shares of Auteco (“Auteco
Shares”) in connection with the execution of the Pickle Crow Earn-In Agreement.

113

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The key terms of the Pickle Crow Earn-In Agreement are as follows:

Stage 1 Earn-In (51% earn-in)

Three-year initial earn-in period for Auteco to acquire a 51% interest in PC Gold (and thereby a 51% interest in the Pickle Crow Project) by:

● incurring  $5  million  of  exploration  and  environmental  expenditures  on  the  Pickle  Crow  Project,  of  which  $750,000  in  exploration  expenditures  must  be  incurred

within the first 12 months; and

● issuing an additional 100,000,000 Auteco Shares to First Mining (the “Stage 1 Earn-In Shares”).

Stage 2 Earn-In (additional 19% to earn-in to 70%)

Upon  completion  of  the  Stage  1  Earn-In,  Auteco  will  have  a  two-year  follow-on  period  to  acquire  an  additional  19%  interest  in  PC  Gold  (and  thereby  an  additional  19%
interest in the Pickle Crow Project), by:

● incurring a further $5 million of exploration expenditures on the Pickle Crow Project;

● paying First Mining $1 million in cash payment within 90 days of incurring the above-mentioned additional exploration expenditures; and

● granting First Mining a 2% NSR royalty on the Pickle Crow Project (1% of which can be bought back by Auteco for US$2.5 million).

Buy-In (additional 10% to earn-in to 80%)

Upon completion of the Stage 2 Earn-In, Auteco will have an option to acquire an additional 10% of PC Gold (and thereby an additional 10% interest in the Pickle Crow
Project), exercisable at any time after completion of the Stage 2 Earn-In, by paying First Mining $3 million in cash.

114

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additional Terms

● Upon completion of the Stage 1 Earn-in, First Mining and Auteco (through a wholly-owned subsidiary) will execute a joint venture shareholders’ agreement with

respect to PC Gold (at which point PC Gold will become a joint venture company).

● First Mining will be free carried, at a 20% interest, until the earlier of the termination of the Pickle Crow Earn-In Agreement or a decision to mine by Auteco.

Auteco  will  require  shareholder  approval  to  issue  the  Stage  1  Earn-In  Shares  to  First  Mining.  We  may  terminate  the  Pickle  Crow  Earn-In Agreement  if  such  shareholder
approval is not obtained.

A copy of the Pickle Crow Earn-In Agreement is available under our SEDAR profile at www.sedar.com.

Silver Stream Agreement

On June 10, 2020, First Mining and its wholly-owned subsidiary, Gold Canyon, entered into the Silver Stream Agreement with First Majestic pursuant to which First Majestic
agreed to purchase 50% of the payable silver produced from Springpole for the life of the project.

The key terms of the Silver Stream Agreement are as follows:

Consideration Details

● In return for its share of payable silver produced from the Springpole Project once production has commenced, First Majestic will make ongoing cash payments to
First Mining equal to 33% of the lesser of the average spot price of silver for the applicable calendar quarter, and the spot price of silver at the time of delivery,
subject to a price cap of US$7.50 per ounce of silver (the “Price Cap”). The Price Cap is subject to annual inflation escalation of 2%, commencing at the start of the
third year of commercial production at Springpole.

● First  Majestic  agreed  to  pay  US$10,000,000  to  First  Mining  upon  closing  of  transaction,  with  US$2,500,000  of  this  amount  payable  in  cash,  and  the  remaining
US$7,500,000  payable  in  common  shares  of  First  Majestic  (the  “First Majestic Shares”)  based  on  the  volume-weighted  average  trading  price  (“VWAP”) of the
First Majestic Shares on the TSX for the 20 trading days up to the day immediately prior to the closing date. These cash and share payments were made to First
Mining when the Silver Stream transaction closed on June 10, 2020.

● First Majestic agreed to pay First Mining an additional US$7,500,000 within five business days of a public announcement by First Mining of the completion of a
positive PFS for Springpole, with US$3,750,000 of this amount payable in cash, and the remaining US$3,750,000 payable in First Majestic Shares (based on the 20-
day VWAP of First Majestic Shares as of the date of First Mining’s public announcement). These cash and share payments were made to First Mining five business
days after the Company’s news release in January 2021 announcing the positive results of a PFS for the Springpole Project.

● First  Majestic  will  pay  a  final  amount  of  US$5,000,000  to  First  Mining  upon  the  Company  receiving  approval  of  either  a  federal  or  provincial  Environmental
Assessment for Springpole, with US$2,500,000 million of this amount payable in cash, and the remaining US$2,500,000 million payable in First Majestic Shares
(based on the 20-day VWAP of First Majestic Shares as of the date of such approval).

115

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Other Transaction Terms

● First Mining agreed to issue 30 million Warrants to First Majestic on the closing date of the Silver Stream Transaction, with each Warrant entitling First Majestic to
purchase one common share of First Mining at an exercise price of $0.40 for a period of five years. These warrants were issued to First Majestic when the Silver
Stream transaction closed on June 10, 2020.

● We  have  the  right  to  repurchase  50%  of  the  Silver  Stream  by  paying  US$22,500,000  to  First  Majestic  at  any  time  prior  to  the  commencement  of  commercial

production at Springpole.

● We have granted a right of first refusal to First Majestic with respect to any future silver stream financings for Springpole.

● First Mining and First Majestic agreed to form a three-member technical committee (the “Technical Committee”) comprised of two members from First Mining and
one  member  from  First  Majestic.  The  Technical  Committee  will  advise  First  Mining  on  metallurgical  testing,  process  flow  sheet  development  and  through  the
completion of the PFS and Feasibility studies for Springpole. This Technical Committee was established following the closing of the Silver Stream transaction on
June 10, 2020.

Treasury Metals SPA

On  June  3,  2020,  Treasury  Metals  and  First  Mining  entered  into  the  Treasury  Metals  SPA  pursuant  to  which  Treasury  Metals  agreed  to  acquire  all  of  the  issued  and
outstanding shares of Tamaka, a wholly-owned subsidiary of First Mining at that time that owns the Goldlund Project (through its own wholly-owned subsidiary, Goldlund
Resources Inc.).

The key terms of the Treasury Metals SPA are as follows:

Consideration Details

● In exchange for acquiring all of the issued and outstanding shares of Tamaka, Treasury Metals agreed to issue First Mining 130,000,000 common shares of Treasury

Metals (“TML Shares”) and 35,000,000 Warrants of Treasury Metals (“TML Warrants”) with an exercise price of $0.50 and a three-year term.

● Treasury Metals agreed to grant First Mining a 1.5% NSR royalty on all claims that comprise the Goldlund Project, 0.5% of which can be bought back by Treasury

Metals at any time by paying the $5,000,000 in cash to First Mining.

● Treasury Metals will pay $2,500,000 in cash to First Mining upon receipt of a mining lease to extract material from an open pit mine at the Goldlund Project.

● Treasury Metals will pay $2,500,000 in cash to First Mining upon 300,000 tonnes of ore being extracted from a mine at the Goldlund Project.

116

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Other Transaction Terms

● First  Mining  has  agreed  to  use  commercially  reasonable  efforts  to  distribute  up  to  70,000,000  TML  Shares,  and  all  35,000,000  TML  Warrants,  to  First  Mining's
shareholders  within  twelve  months  of  the  closing  of  the  Treasury  Metals  Transaction  (the  “Distribution”),  and  Treasury  Metals  has  agreed  to  use  commercially
reasonable efforts to list the TML Warrants on the TSX and the OTCQX following the Distribution.

● Upon closing of the Treasury Metals Transaction, First Mining will be entitled to nominate three directors of a seven-member Board of Directors of Treasury Metals
(the “Treasury Board”). After closing, First Mining will continue to have the right to nominate three directors to the Treasury Board until the later of (1) the next
meeting  of  shareholders  of  Treasury  Metals  at  which  directors  are  to  be  elected,  and  (2)  the  earlier  of  (i)  the  date  of  the  Distribution,  and  (ii)  the  date  that  is  12
months from the closing date of the transaction.

● If at any time after closing First Mining holds between 10% and 19.9% of the issued and outstanding TML Shares, we will have the right to nominate two directors
to the Treasury Board. If our share ownership in Treasury Metals is reduced to between 5% and 9.9% of the issued and outstanding TML Shares, we will have the
right to only nominate one director to the Treasury Board.

● Upon  closing, Treasury  Metals  will  constitute  a  Technical  Committee  to  oversee  project  development  of  the  consolidated  Goldlund-Goliath  assets. The  Technical

Committee will consist of four members, with First Mining initially entitled to appoint two members of the committee.

● Following closing, as long as we hold more than 19.9% of the issued and outstanding TML Shares, we will continue to have the right to appoint two members of the

Technical Committee.

● If at any time after closing the Treasury Metals Transaction our share ownership is reduced to between 10% and 19.9% of the issued and outstanding TML Shares,

we will have the right to only nominate one member of the Technical Committee.

After the Treasury Metals Transaction closed, Treasury Metals effected a three (3) for one (1) consolidation of the issued and outstanding TML Shares. As a result, following
this consolidation, First Mining now holds 43,333,333 TML Shares and 11,666,666 TML Warrants.

To  our  knowledge,  the  total  number  of  common  shares  that  the  directors  and  officers  as  a  group  either:  (i)  beneficially  owned;  or  (ii)  exercised  direction  or  control  over,
directly or indirectly, as at the date of this AIF was 21,398,146  common shares. This represents approximately 3.1% of our outstanding common shares as at the date of this
AIF (on an undiluted basis).

Interest of management and others in material transactions

To the best of our knowledge, none of the directors, executive officers or shareholders that either: (i) beneficially own; or (ii) control or direct, directly or indirectly, over 10%
of any class of our outstanding securities, nor their associates or affiliates, have or have had within the three most recently completed financial years, any material interests,
direct or indirect, in transactions which have materially affected, or are reasonably expected to materially affect, our Company.

Conflicts of interest

Certain directors and officers will be engaged in, and will continue to engage in, other business activities on their own behalf and on behalf of other companies (including
mineral companies) and, as a result of these and other activities, such directors and officers may become subject to conflicts of interest. The BCBCA provides that if a director
has a material interest in a contract or proposed contract or agreement that is material to the issuer, the director must disclose his interest in such contract or agreement and
must refrain from voting on any matter in respect of such contract or agreement, subject to and in accordance with the BCBCA. To the extent that conflicts of interest arise,
such conflicts will be resolved in accordance with the provisions of the BCBCA and in accordance with our Code of Business Conduct and Ethics.

Other information about our directors and officers

None  of  our  directors  or  officers,  or  a  shareholder  holding  a  sufficient  number  of  securities  of  First  Mining  to  affect  materially  the  control  of  our  Company,  is  or  was  a
director or executive officer of another company (including our Company) in the past 10 years that:

● was  subject  to  a  cease  trade  or  similar  order,  or  an  order  denying  that  company  any  exemption  under  securities  legislation  that  was  in  effect  for  more  than  30

consecutive days, while the director or executive officer held that role with the company;

● was involved in an event while the director or executive officer was acting in that capacity that resulted in the company being subject to one of the above orders after

Audit Committee information

National Instrument 52-110 Audit Committees (“NI 52-110”) requires us to have an audit committee (the “Audit Committee”) comprised of not less than three directors all of
whom are “independent” and “financially literate” (as such terms are defined in NI 52-110). NI 52-110 also requires us to disclose in this AIF certain information regarding
the Audit Committee. That disclosure is set out below.

Overview

The Company’s Audit Committee is principally responsible for:

● recommending to our Board the external auditor to be nominated for election by the shareholders at each annual general meeting and negotiating the compensation of

such external auditor;

● overseeing the work of the external auditor;

● reviewing  our  annual  and  interim  financial  statements,  MD&A  and  press  releases  regarding  earnings  before  they  are  reviewed  and  approved  by  our  Board  and

publicly disseminated; and

● reviewing  our  financial  reporting  procedures  and  internal  controls  to  ensure  adequate  procedures  are  in  place  for  our  public  disclosure  of  financial  information

extracted or derived from our financial statements.

Committee charter

A copy of the Audit Committee’s charter is attached as Appendix “A” to this AIF.

Composition of the Audit Committee

Our current Audit Committee consists of Raymond Polman (current chairman of the Audit Committee), Keith Neumeyer and Richard Lock.

NI 52-110 provides that a member of an audit committee is “independent” if the member has no direct or indirect material relationship with the Company, which could, in the
view of our Board, reasonably interfere with the exercise of the member’s independent judgment. All of the members of our Audit Committee are “independent” within the
meaning of NI 52-110.

NI 52-110 provides that an individual is “financially literate” if he or she has the ability to read and understand a set of financial statements that present a breadth and level of
complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the Company’s
financial statements. All of the members of our Audit Committee are “financially literate” as that term is defined in NI 52-110.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of First Mining Gold Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of First Mining Gold Corp. and its subsidiaries (together, the Company) as of
December 31, 2020 and 2019, and the related consolidated statements of net loss and comprehensive income (loss), cash flows and changes in equity for the
years then ended, including the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and its financial performance and
its cash flows for the years then ended in conformity with International Financial Reporting Standards as issued by the International Accounting Standards
Board.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or
fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud,
and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as
well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Expressed in Canadian dollars unless otherwise noted, tabular amounts are expressed in thousands of Canadian dollars)

1. NATURE OF OPERATIONS

First Mining Gold Corp. (the “Company” or “First Mining”) is a public company which is listed on the Toronto Stock Exchange (the “TSX”) under the symbol “FF”, on the
OTCQX under the symbol “FFMGF”, and on the Frankfurt Stock Exchange under the symbol “FMG”. The Company’s head office and principal address is Suite 2070 – 1188
West Georgia Street, Vancouver, British Columbia, Canada, V6E 4A2.

First Mining was incorporated on April 4, 2005. The Company changed its name to First Mining Gold Corp. in January 2018.

First Mining is a Canadian gold company focused on the permitting and development of the Springpole Gold Project in northwestern Ontario. The Company also holds a
significant equity investment in Treasury Metals Inc. (“Treasury Metals”) (TSX: TML) (Note 4) which is advancing the Goliath-Goldlund gold complex in Ontario towards a
construction  decision.  First  Mining’s  portfolio  of  gold  projects  in  eastern  Canada  also  includes  Pickle  Crow  (being  advanced  in  partnership  with  Auteco  Minerals  Ltd.
(“Auteco”) (ASX: AUT)), Cameron, Hope Brook, Duparquet, Duquesne, and Pitt.

In March 2020, the World Health Organization declared a global pandemic related to the virus known as COVID-19. As the Company does not have production activities, the
ability  to  fund  ongoing  exploration  is  affected  by  the  availability  of  financing.  Due  to  market  uncertainty  arising  from  the  impacts  of  COVID-19  the  Company  may  be
restricted in its ability to raise additional funding. The impact of COVID-19 on the Company over time is not determinable; however, its effects may have a material impact
on the Company’s financial position, results of operations and cash flows in future periods.

2. BASIS OF PRESENTATION

These consolidated annual financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting
Standards Board (“IFRS”), effective for the Company’s reporting for the year ended December 31, 2020.

These consolidated financial statements have been prepared on a historical cost basis, except for financial instruments classified as fair value through profit and loss or fair
value through other comprehensive income (loss), which are stated at their fair value. The consolidated annual financial statements are presented in thousands of Canadian
dollars, unless otherwise noted, and tabular amounts are expressed in thousands of Canadian dollars.

The functional currency of the Company and its Canadian subsidiaries is the Canadian dollar while the functional currency of the Company’s non-Canadian subsidiaries is the

3. ACCOUNTING POLICIES

These consolidated annual financial statements have been prepared using the following accounting policies:

a)

Financial Instruments

(i)

Classification

The Company classifies its financial instruments in the following categories: at fair value through profit and loss (“FVTPL”), at fair value through other comprehensive
income (loss) (“FVTOCI”) or at amortized cost. The Company determines the classification of financial assets at initial recognition. The classification of debt instruments
is driven by the Company’s business model for managing the financial assets and their contractual cash flow characteristics. Equity instruments that are held for trading are
classified  as  FVTPL.  For  other  equity  instruments,  at  the  time  of  acquisition  the  Company  can  make  an  irrevocable  election  (on  an  instrument-by-instrument  basis)  to
designate them as at FVTOCI. Financial liabilities are measured at amortized cost, unless they are required to be measured at FVTPL (such as instruments held for trading
or derivatives) or the Company has opted to measure them at FVTPL.

(ii) Measurement

Financial assets at FVTOCI
Elected investments in equity instruments at FVTOCI are initially recognized at fair value plus transaction costs. Subsequently they are measured at fair value, with gains
and losses recognized in other comprehensive income (loss).

Financial assets and liabilities at amortized cost
Financial assets and liabilities at amortized cost are initially recognized at fair value plus or minus transaction costs, respectively, and subsequently carried at amortized cost
less any impairment.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Expressed in Canadian dollars unless otherwise noted, tabular amounts are expressed in thousands of Canadian dollars)

3. ACCOUNTING POLICIES (Continued)

Financial assets and liabilities at FVTPL
Financial assets and liabilities carried at FVTPL are initially recorded at fair value and transaction costs are expensed in the consolidated statements of net (loss) income.
Realized  and  unrealized  gains  and  losses  arising  from  changes  in  the  fair  value  of  the  financial  assets  and  liabilities  held  at  FVTPL  are  included  in  the  consolidated
statements of net (loss) income in the period in which they arise. Where management elected to recognize a financial liability at FVTPL, any changes associated with the
Company’s own credit risk will be recognized in other comprehensive income (loss).

(iii)

Impairment of financial assets at amortized cost

The Company recognizes a loss allowance for expected credit losses on financial assets that are measured at amortized cost.

At each reporting date, the Company measures the loss allowance for a financial asset at an amount equal to the lifetime expected credit losses if the credit risk on the
financial asset has increased significantly since initial recognition. If at the reporting date, the credit risk on the financial asset has not increased significantly since initial
recognition, the Company measures the loss allowance for the financial asset at an amount equal to the twelve month expected credit losses. The Company recognizes in
the  consolidated  statements  of  net  (loss)  income,  as  an  impairment  gain  or  loss,  the  amount  of  expected  credit  losses  (or  reversal)  that  is  required  to  adjust  the  loss
allowance at the reporting date to the amount that is required to be recognized.

(iv) Derecognition

Financial assets
The  Company  derecognizes  financial  assets  only  when  the  contractual  rights  to  cash  flows  from  the  financial  assets  expire,  or  when  it  transfers  the  financial  assets  and
substantially  all  of  the  associated  risks  and  rewards  of  ownership  to  another  entity.  Gains  and  losses  on  derecognition  are  generally  recognized  in  the  consolidated
statements  of  net  (loss)  income.  However,  gains  and  losses  on  derecognition  of  financial  assets  classified  as  FVTOCI  remain  within  accumulated  other  comprehensive
income (loss).

Financial liabilities
The  Company  derecognizes  financial  liabilities  only  when  its  obligations  under  the  financial  liabilities  are  discharged,  cancelled  or  expired.  Generally,  the  difference
between the carrying amount of the financial liability derecognized and the consideration paid and payable, including any non-cash assets transferred or liabilities assumed,
is recognized in the consolidated statements of net (loss) income.

b)

Cash and Cash Equivalents

Cash and cash equivalents include cash and short-term deposits that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes
in value. The carrying amounts of cash and cash equivalents approximate fair value due to the short-term maturities of these instruments.

3. ACCOUNTING POLICIES (Continued)

c)

Mineral Properties

Once the legal right to explore a property has been acquired, costs directly related to exploration and evaluation expenditures are recognized and capitalized, in addition to the
acquisition  costs.  These  direct  expenditures  include  such  costs  as  mineral  concession  taxes,  option  payments,  wages  and  salaries,  surveying,  geological  consulting  and
laboratory costs, field supplies, travel and administration. Costs not directly attributable to exploration and evaluation activities, including general administrative overhead
costs, are expensed in the period in which they are incurred.

The  Company  may  occasionally  enter  into  option  or  royalty  arrangements,  whereby  the  Company  will  transfer  part  of  its  mineral  properties,  as  consideration,  for  an
agreement by the transferee to meet certain exploration and evaluation expenditures which would have otherwise been undertaken by the Company. Any cash consideration
received from the agreement is credited against the costs previously capitalized to the mineral interest given up by the Company, with any excess cash accounted for as a gain
on disposal.

The  Company  assesses  exploration  and  evaluation  assets  for  impairment  when  facts  and  circumstances  suggest  that  the  carrying  amount  of  an  asset  may  exceed  its
recoverable amount. The recoverable amount is the higher of the asset’s fair value less costs to sell and value in use.

Once the technical feasibility and commercial viability of extracting a mineral resource has been determined, the property is considered to be a mine under development and
is classified as ‘mines under construction’. Exploration and evaluation assets are also tested for impairment before the assets are transferred to mineral properties and mine
development costs.

d)

Impairment of Non-Financial Assets

Mineral  properties  are  subject  to  impairment  tests  whenever  events  or  changes  in  circumstances  indicate  that  their  carrying  amount  may  not  be  recoverable.  Where  the
carrying  value  of  an  asset  exceeds  its  recoverable  amount,  which  is  the  higher  of  value  in  use  and  fair  value  less  costs  to  sell,  the  asset  is  written  down  accordingly.  An
impairment loss is charged to profit or loss.

For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are largely independent cash flows (cash-generating units). As a result, some
assets may be tested individually for impairment and some are tested at a cash-generating unit level.

Impairment reviews for the Company’s exploration and evaluation stage mineral properties are carried out on a property by property basis, with each property representing a
single cash generating unit. An impairment review for an exploration and evaluation asset is undertaken when indicators of impairment arise, but typically when one of the
following circumstances apply:

● The right to explore the area has expired or will expire in the near future with no expectation of renewal;
● Substantive expenditure on further exploration for and evaluation of mineral resources in the area is neither planned nor budgeted;
● No commercially viable deposits have been discovered, and the decision had been made to discontinue exploration in the area; and
● Sufficient work has been performed to indicate that the carrying amount of the expenditure carried as an asset will not be fully recovered.

3. ACCOUNTING POLICIES (Continued)

e)

Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation and accumulated impairment losses. The initial cost of an asset comprises its purchase price or
construction  cost,  any  costs  directly  attributable  to  bringing  the  asset  into  operation  and,  where  applicable,  the  initial  estimation  of  any  asset  retirement  obligation.  The
purchase price or construction cost is the aggregate amount paid and the fair value of any other consideration given to acquire the asset.

Depreciation is recognized in profit or loss on a straight-line basis over the following estimated useful lives:

Buildings
Machinery and equipment
Furniture and fixtures
Vehicles
Computer equipment
Computer software

10 years
5 years
5 years
5 years
3 years
1 year

Depreciation methods, useful lives and residual values are reviewed at each financial year-end and adjusted if appropriate.

f)

Environmental Reclamation Provision

The Company is subject to various government laws and regulations relating to environmental disturbances caused by exploration and evaluation activities. The present value
of the estimated costs of legal and constructive obligations required to restore the exploration sites is recognized in the year in which the obligation is incurred.
The nature of the reclamation activities includes restoration and revegetation of the affected exploration sites.

When  a  liability  is  recognized,  the  present  value  of  the  estimated  costs  (discounted  using  a  risk-free  rate)  is  capitalized  by  increasing  the  carrying  amount  of  the  related
exploration property. Over time, the discounted liability is increased for the changes in present value based on current market discount rates and liability specific risks.

Additional  environment  disturbances  or  changes  in  reclamation  costs  will  be  recognized  as  additions  to  the  corresponding  assets  and  reclamation  provision  in  the  year  in
which they occur.

g)

Income Taxes

Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in net income except to the extent that it relates to a business combination
or items recognized directly in equity or in other comprehensive loss.

Current income taxes are recognized for the estimated income taxes payable or receivable on taxable income or loss for the current year and any adjustment to income taxes
payable in respect of previous years. Current income taxes are determined using tax rates and tax laws that have been enacted or substantively enacted by the year-end date.

Deferred tax assets and liabilities are recognized where the carrying amount of an asset or liability differs from its tax base, except for taxable temporary differences arising
on the initial recognition of goodwill and temporary differences arising on the initial recognition of an asset or liability in a transaction which is not a business combination
and at the time of the transaction affects neither accounting nor taxable profit or loss.

3. ACCOUNTING POLICIES (Continued)

Recognition of deferred tax assets for unused tax losses, tax credits and deductible temporary differences is restricted to those instances where it is probable that future taxable
profit will be available against which the deferred tax asset can be utilized. At the end of each reporting year the Company reassesses unrecognized deferred tax assets. The
Company recognizes a previously unrecognized deferred tax asset to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be
recovered.

h)

Share Capital

Equity instruments are contracts that give a residual interest in the net assets of the Company. Financial instruments issued by the Company are classified as equity only to the
extent that they do not meet the definition of a financial liability or financial asset. The Company’s common shares are classified as equity instruments.

Incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction, net of tax, from the proceeds.

Consideration received from financings involving units consisting of common shares and warrants is allocated to the share capital and the warrant reserve accounts using the
relative fair value method. As prescribed by this method, the consideration is allocated to the value of share capital and warrant reserve on a pro rata basis. The share capital is
valued at the closing share price of the Company on the completion date of the private placement and the warrant reserve is valued using the Black-Scholes option pricing
model.

i)

Flow-Through Units and Shares

The Company may, from time to time, issue flow-through common shares or units to finance a portion of its Canadian exploration programs. Pursuant to the terms of the
flow-through share agreements and the Income Tax Act (Canada) (the “ITA”), these equity instruments transfer the tax deductibility of qualifying resource expenditures to
investors.

Upon the issuance of a flow-through share, the Company bifurcates the flow-through share into i) fair value of capital stock issued, based on market price at time of issuance,
and ii) the residual as a flow-through share premium, which is recognized as a liability. Upon the issuance of a flow-through unit, the Company bifurcates the flow-through
unit  into  i)  relative  fair  value  of  capital  stock  issued,  ii)  relative  fair  value  of  a  warrant,  and  iii)  the  residual  as  a  flow-through  share  premium,  which  is  recognized  as  a
liability.

Upon incurring qualifying expenses, the Company derecognizes the flow-through share premium liability and recognizes a credit to deferred tax expense (recovery). Proceeds
received from the issuance of flow-through shares are to be used for Canadian resource property exploration expenditures within a certain time period as prescribed by the
Government of Canada’s flow-through regulations, as contained in the ITA. The portion of the proceeds received but not yet expended at the end of the Company’s relevant
reporting  period  is  disclosed  separately  in  the  notes  to  the  financial  statements  as  flow-through  expenditure  commitments  (Note  14).  The  Company  is  also  subject  to  Part
XII.6  of  the  ITA,  which  imposes  a  tax  on  flow-through  proceeds  renounced  under  the  “Look-back  Rule”,  in  accordance  with  the  Government  of  Canada’s  flow-through
regulations. When applicable, this tax is accrued until paid.

j)

Loss per Share

Basic  loss  per  share  is  calculated  by  dividing  the  net  loss  for  the  year  by  the  weighted  average  number  of  shares  outstanding  during  the  year.  Diluted  loss  per  share  is
calculated using the treasury stock method. Under the treasury stock method, the weighted average number of shares outstanding used in the calculation of diluted income or
loss  per  share  assumes  that  the  deemed  proceeds  received  from  the  exercise  of  stock  options,  share  purchase  warrants  and  their  equivalents  would  be  used  to  repurchase
common shares of the Company at the average market price during the year, if they are determined to have a dilutive effect. In periods when the Company has generated a net
loss, stock options and share purchase warrants are not included in the computation of diluted loss per share as they are anti-dilutive.

k)

Share-based Payments

Where equity-settled share options are granted to employees, the fair value of the options at the date of grant, measured using the Black-Scholes option pricing model, is
charged to the statement of comprehensive loss or capitalized to mineral properties over the vesting period using the graded vesting method. Performance vesting conditions
are taken into account by adjusting the number of equity instruments expected to vest at each reporting date so that, ultimately, the cumulative amount recognized over the
vesting period is based on the number of options that eventually vest. Charges for options that are forfeited before vesting are reversed from share-based payment reserve.

Where equity-settled share options are granted to non-employees, they are measured at the fair value of the goods or services received. However, if the value of goods or
services received in exchange for the options cannot be reliably estimated, the options are measured using the Black-Scholes option pricing model.

All equity-settled share-based payments are reflected in share-based payment reserve, until exercised. Upon exercise, shares are issued from treasury and the amount reflected
in share-based payment reserve is credited to share capital, together with any consideration received.

l)

Leases

The Company recognizes a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for short-term leases
(defined as leases with a lease term of 12 months or less) and leases of low value assets. For new leases, a right-of-use asset is initially measured at the amount of the liability
plus any initial direct costs. After lease commencement, the lessee shall measure the right-of-use asset at cost less accumulated depreciation and accumulated impairment.

m)

Segment Reporting

Operating  segments  are  reported  in  a  manner  consistent  with  the  internal  reporting  provided  to  the  chief  operating  decision-maker.  The  chief  operating  decision-maker  is
responsible for allocating resources and assessing performance of the operating segment.

n)

Investment in associate

An associate is an entity over which the Company has significant influence, and which is neither a subsidiary nor a joint arrangement.

The Company has significant influence over an entity when it has the power to participate in the financial and operating policy decisions of the associate but does not have
control or joint control.

The Company’s investment in the common shares of Treasury Metals (Note 4) has been treated as an investment in associate and accounted for using the equity method.

Under  the  equity  method,  the  Company’s  investment  in  the  common  shares  of  the  associate  is  initially  recognized  at  cost  and  subsequently  increased  or  decreased  to
recognize the Company’s share of net income and losses of the associate, after any adjustments necessary to give effect to uniform accounting policies, any other movement
in the associate’s reserves, and for impairment losses after the initial recognition date. The Company’s share of income and losses of the associate is recognized in net income
during the period.

Dividends and repayment of capital received from an associate are accounted for as a reduction in the carrying amount of the Company’s investment.

At the end of each reporting period, the Company assesses whether there is any objective evidence that an investment in an associate is impaired. Objective evidence includes
observable data indicating there is a measurable decrease in the estimated future cash flows of the investee’s operations. A significant or prolonged decline in the fair value of
an equity investment below its cost is also objective evidence of impairment. When there is objective evidence that an investment is impaired, the carrying amount of such
investment is compared to its recoverable amount, being the higher of its fair value less costs of disposal and value-in-use. If the recoverable amount of an investment is less
than its carrying amount, the carrying amount is reduced to its recoverable amount and an impairment loss, being the excess of carrying amount over the recoverable amount,
is  recognized  in  the  period  in  which  the  relevant  circumstances  are  identified.  When  an  impairment  loss  reverses  in  a  subsequent  period,  the  carrying  amount  of  the
investment is increased to the revised estimate of recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have
been determined had an impairment loss not been previously recognized. A reversal of an impairment loss is recognized in net income in the period in which the reversal
occurs.

o)

Accounting Policy Judgements and Estimation Uncertainty

The Company’s management makes judgments in its process of applying the Company’s accounting policies in the preparation of its consolidated financial statements. In
addition, the preparation of the financial data requires the Company’s management to make estimates of the impacts of uncertain future events on the carrying amounts of the
Company’s assets and liabilities at the end of the reporting period, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ
from those estimates as the estimation process is inherently uncertain. Estimates are reviewed on an ongoing basis based on historical experience and other factors that are
considered relevant under the circumstances. Revisions to estimates and the resulting impacts on the carrying amounts of the Company’s assets and liabilities are accounted
for prospectively.

3. ACCOUNTING POLICIES (Continued)

The following discusses accounting policy judgments and the sources of estimation uncertainty:

(i)

Accounting Policy Judgements

Mineral Property Impairment Indicators
In accordance with the Company’s accounting policy for its mineral properties, exploration and evaluation expenditures on mineral properties are capitalized. There is no
certainty  that  the  expenditures  made  by  the  Company  in  the  exploration  of  its  property  interests  will  result  in  discoveries  of  commercial  quantities  of  minerals.  The
Company applies judgment to determine whether indicators of impairment exist for these capitalized costs.

Management uses several criteria in making this assessment, including the period for which the Company has the right to explore, expected renewals of exploration rights,
whether  substantive  expenditures  on  further  exploration  and  evaluation  of  mineral  properties  are  budgeted,  and  evaluation  of  the  results  of  exploration  and  evaluation
activities up to the reporting date.

Impairment of Investment in Associate
With  respect  to  its  investment  in  associate,  the  Company  is  required  to  make  estimates  and  judgments  about  future  events  and  circumstances  and  whether  the  carrying
amount  of  the  asset  exceeds  its  recoverable  amount.  Recoverability  depends  on  various  factors,  including  the  identification  of  economic  recoverability  of  reserves  at
Treasury Metals’ exploration properties, the ability of Treasury Metals to obtain the necessary financing to complete the development, and future profitable production or
proceeds from the disposition of the Treasury Metals shares themselves. The publicly quoted share price of Treasury Metals is also a source of objective evidence about the
recoverable amount of the equity investment.

Milestone Payments per Treasury Share Purchase Agreement

The  Company  applied  judgment  in  the  determination  of  whether  to  recognize  the  contingent  milestone  payments  in  accordance  with  the  Treasury  Share  Purchase
Agreement (defined in Note 4). In management’s judgment, there is uncertainty of these milestones being reached. Management considered the expected length of time that
may pass before this uncertainty is resolved, as well as the fact that achievement of the milestones is outside of the Company’s control. Therefore, the milestone payments
have not been recognized as assets as at December 31, 2020.

(ii)

Estimation Uncertainty

Determining Amount and Timing of Reclamation Provisions
A  reclamation  provision  represents  the  present  value  of  estimated  future  costs  for  the  reclamation  of  the  Company’s  mineral  properties.  These  estimates  include
assumptions as to the future activities, cost of services, timing of the reclamation work to be performed, inflation rates and interest rates. The actual cost to reclaim a mine
or exploration property may vary from the estimated amounts because there are uncertainties with respect to the extent of required future remediation activities, as studies
are currently ongoing, and uncertainties in factors used to estimate the cost and potential changes in regulations or laws governing the reclamation of a mineral property.
Management periodically reviews the reclamation requirements and adjusts the liability as new information becomes available and will assess the impact of new regulations
and laws as they are enacted.

3. ACCOUNTING POLICIES (Continued)

Valuation of Mineral Property Investments

The Company makes estimates and assumptions that affect the carrying value of its mineral property investments, which are comprised of equity interests in the shares of
private companies. These financial assets are designated as fair value through other comprehensive income (loss), and management needs to determine the fair value as at
each period end. As there is no observable market data which can be used to determine this fair value, management uses property specific and market-based information to
determine whether a significant change in the fair value of these investments has occurred. Changes to the property specific and market-based variables could result in the
fair value being less than or greater than the amount recorded.

Fair Value of Silver Stream Derivative Liability

The determination of the fair value of the Silver Stream is an area of significant estimation uncertainty. The fair value is calculated by utilising a Monte Carlo simulation
valuation model. A Monte Carlo valuation model relies on random sampling and is often used when modeling cash flows with many inputs and where there is significant
uncertainty  in  the  future  value  of  inputs  and  where  the  movement  of  the  inputs  can  be  independent  of  each  other.  The  key  inputs  used  in  the  Silver  Stream  fair  value
calculation  are  further  disclosed  in  Note  5.  Changes  in  the  inputs  to  the  valuation  model  may  result  in  material  changes  in  the  fair  value  of  the  silver  stream  derivative
liability and the amount of fair value gains or losses recognized in the statement of net loss and comprehensive loss in future periods.

Fair Value of Treasury Metals Warrants
The Company made assumptions when estimating the fair value of its warrants held in Treasury Metals, as described in Note 4. The fair value of the warrants at the date of
grant  and  at  subsequent  reporting  dates  is  measured  using  the  Black‐Scholes  pricing  model.  Changes  in  the  input  assumptions  can  significantly  affect  the  fair  value
estimate.

Fair Value of the Option – PC Gold
The Company has made assumptions when estimating the fair value of this option liability which arises under the terms of the Earn-In Agreement described in Note 8(a).
As there is no observable market data which can be used to determine the fair value of the Option – PC Gold liability, management uses property specific and market-based
information  to  determine  whether  a  significant  change  in  the  fair  value  of  the  option  liability  has  occurred.  The  specific  assumptions  made  are  disclosed  in  Note  8(a).
Changes in these assumptions can significantly affect the fair value estimate.

p)

Accounting Standards Issued but Not Yet Applied

There are no IFRS or International Financial Reporting Interpretations Committee interpretations that are not yet effective that would be expected to have a material impact
on the Company’s consolidated financial statements.

4. INVESTMENT IN TREASURY METALS

a)

Treasury Share Purchase Agreement Overview

On August 7, 2020, First Mining completed its transaction with Treasury Metals under a share purchase agreement (the “Treasury Share Purchase Agreement”), pursuant to
which Treasury Metals agreed to acquire all of the issued and outstanding shares of Tamaka Gold Corporation, a previously wholly-owned subsidiary of the Company, and
100%  owner  of  the  Goldlund  Project.  Under  the  terms  of  the  Treasury  Share  Purchase  Agreement,  First  Mining  received  total  consideration  of  $91,521,000  which  was
comprised of (i) 43.33 million common shares (post-consolidation) of Treasury Metals (“Treasury Metals Shares”); (ii) 11.67 million common share purchase warrants (post-
consolidation) of Treasury Metals (“Treasury Metals Warrants”) with an exercise price of $1.50 for a 3-year term; (iii) a retained 1.5% Net Smelter Returns (“NSR”) royalty
on Goldlund (0.5% of which can be bought back by Treasury Metals for $5 million in cash); and (iv) the right to certain contingent milestone payments totaling $5 million,
payable in cash on certain key advancements at Goldlund which have not been recorded as at December 31, 2020.

b)

Initial Recognition of Consideration Received

The components of the consideration received in connection with the sale of Tamaka comprised the following:

● $78,000,000 for 43.33 million Treasury Metals Shares (the “Share Consideration”);
●   $9,812,000 for 11.67 million Treasury Metals Warrants (the “Warrant Consideration”) - Note 7; and
●   $3,709,000 for the retained 1.5% NSR (the “NSR Consideration”) - Note 8.

$91,521,000 

Share Consideration

The  Company  applies  equity  accounting  for  the  investment  in  the  Treasury  Metals  Shares.  The  fair  value  of  the  Treasury  Metals  Shares  at  closing  of  $78,000,000  was
determined using the quoted price of Treasury Metals common shares on August 7, 2020. Upon closing of the transaction, First Mining held approximately 40% (December
31, 2019 - nil) of Treasury Metals common shares (on an undiluted basis) and has nominated three individuals to its Board of Directors. The Company has concluded it has
significant influence over Treasury Metals. The Company is accounting for its investment using the equity method until such time as it no longer has significant influence.

Warrant Consideration

The warrants of Treasury Metals have been accounted for as FVTPL. The Company uses the Black-Scholes option pricing model to calculate the fair value of the warrants
held in Treasury Metals both as at August 7, 2020 and on an ongoing basis. The Company used the following assumptions:

Risk-free interest rate
Expected life (years)
Expected volatility(1)
Expected dividend yield

2020

December 31,
2020

0.23% 

3.00 years 

62.44%

0.20%

2.60 years 

64.42%
Nil 

(1)   The computation of expected volatility was based on Treasury Metals’ historical price volatility, over a period which approximates the expected life of the warrant.

As at December 31, 2020, the fair value of the warrants decreased to $5,772,000 which resulted in a loss of $4,040,000 for the period between August 7, 2020 to December
31, 2020. The loss is recorded within the investments fair value gain (loss) in the statement of net loss and comprehensive income (loss).

NSR Consideration

The 1.5% NSR royalty on Goldlund was measured at a fair value of $3,709,000 and is included as part of “Others” in “Mineral Properties” (Note 8).

c)

Equity Accounting Method for Investment in Treasury Metals and Impairment

As at December 31, 2020 the fair market value of the Company’s investment in common shares of Treasury Metals was $58,500,000, based on the quoted market price. Due
to  the  significant  decline  in  fair  value  of  the  Treasury  Metals  Shares  at  September  30,  2020  the  Company  recorded  an  impairment  of  the  investment  in  Treasury  Metals
amounting to $15,634,000. This impairment was recorded within the impairment of non-current assets in the statement of net loss and comprehensive income (loss). It was
determined that there was no additional impairment as at December 31, 2020.

Obligation to Distribute Investments

In  accordance  with  the  terms  of  a  Shareholders  Agreement  signed  in  connection  with  the  transaction,  First  Mining  is  required  to  distribute  approximately  20.92  million
Treasury  Metals  Shares  and  all  of  the  Treasury  Metals  Warrants  to  its  shareholders  (the  “Distribution”)  within  12  months  of  closing  of  the  transaction.  Following  the
Distribution,  First  Mining  will  retain  approximately  22.41  million  Treasury  Metals  Shares,  leaving  the  Company  with  a  19.9%  interest.  As  at  December  31,  2020,  the
Company recognized a liability for the Distribution of $34,040,000. The liability was recorded with a corresponding entry to accumulated deficit as it represents a distribution
to shareholders.

5. SILVER STREAM DERIVATIVE LIABILITY

a)

Silver Purchase Agreement Overview

On June 10, 2020, the Company entered into a silver purchase agreement (the “Silver Purchase Agreement”) with First Majestic Silver Corp. (“First Majestic”), which closed
on July 2, 2020. Under the terms of the Silver Purchase Agreement, First Majestic agreed to pay First Mining total consideration of US$22.5 million, in three tranches, for the
right to purchase 50% of the payable silver produced from the Springpole Gold Project over the life of the project (the “Silver Stream”) and also received 30 million common
share purchase warrants of First Mining. Each share purchase warrant entitles First Majestic to purchase one common share of First Mining at an exercise price of $0.40 for a
period of five years.

Upon receipt of its share of silver production, First Majestic will make ongoing cash payments to First Mining for each ounce of silver delivered in an amount equal to 33%
of the lesser of the average spot price of silver for the applicable calendar quarter, and the spot price of silver at the time of delivery (the "Silver Cash Price"), subject to a
price  cap  of  US$7.50  per  ounce  of  silver  (the  “Price  Cap”).  The  Price  Cap  is  subject  to  annual  inflation  escalation  of  2%,  beginning  at  the  start  of  the  third  year  after
commencement of production at the project.

First Mining has the right to repurchase 50% of the Silver Stream for US$22.5 million at any time prior to the commencement of production at Springpole (the “Buy-Back
Right”).

b)

Consideration Received and Future Silver Stream Terms

Per the Silver Purchase Agreement, First Majestic paid US$10 million to First Mining on the July 2, 2020 closing date, with US$2.5 million paid in cash and the remaining
US$7.5  million  paid  in  805,698  common  shares  of  First  Majestic.  As  at  December  31,  2020,  the  Company  held  400,000  First  Majestic  common  shares  recorded  in
Investments (Note 7).

Consideration payable for the Silver Stream includes two further tranches (split evenly between cash and First Majestic common shares) based on the achievement of certain
Springpole Gold Project milestones. Upon announcement of the Pre-Feasibility Study (“PFS”) subsequent to December 31, 2020, First Mining received US$7.5 million from
First Majestic (US$3.75 million paid in cash and the remaining US$3.75 million in common shares of First Majestic) (Note 22), with a further US$5 million payable upon
First  Mining  receiving  approval  of  either  a  Federal  or  Provincial  Environmental  Assessment.  (The  three  tranches  of  consideration  totaling  US$22.5  million  constitute  the
“Advance Payment”). In the event of default, First Majestic may terminate the Silver Purchase Agreement and the Advance Payment received by First Mining at that time
would become repayable.

FIRST MINING GOLD CORP.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Expressed in Canadian dollars unless otherwise noted, tabular amounts are expressed in thousands of Canadian dollars)

5. SILVER STREAM DERIVATIVE LIABILITY (Continued)

The Advance Payment amount is used to track the stream balance for commercial, but not accounting purposes. Until the date where the Advance Payment is reduced to nil,
an amount equal to the number of ounces of silver delivered to First Majestic multiplied by the difference between the spot price of silver and the Silver Cash Price shall
reduce the balance of the Advance Payment on the delivery date. In the event the Company exercises the Buy-Back Right by paying US$22.5 million to First Majestic, the
Advance Payment amount shall be reduced to nil.

The Silver Stream has an initial term of 40 years from July 2, 2020. The term is automatically extended by successive 10-year periods as long as the life of mine continues for
the Springpole Gold Project. If upon expiration of the term of the Silver Purchase Agreement, the Company has not sold to First Majestic an amount of silver sufficient to
reduce the Advance Payment to nil, then a refund of the uncredited balance, without interest shall be due and owing by the Company to First Majestic.

The silver delivered to First Majestic may be sourced from the Springpole Gold Project, or the Company may substitute any required refined silver with refined silver from a
source other than the Springpole Gold Project, with the exception of silver purchased on a commodity exchange.

c)

Silver Stream Derivative Liability Fair Value

The Company has concluded that the Silver Stream is a standalone derivative measured at FVTPL. The Company considered whether the Silver Stream would qualify as an
‘own use contract’, whereby it would not require fair value accounting under IFRS. An ‘own use contract’ is one that results in the physical delivery of a company’s own non-
financial asset. The Silver Stream failed to qualify under the ‘own use exemption’ as a result of the silver substitution provisions within the Silver Purchase Agreement. In
addition, the Company has an unavoidable obligation to repay the Advance Payment or deliver the silver to First Majestic.

As of the acquisition date, the estimated fair value of the Silver Stream derivative liability was determined using a discounted cash flow model which incorporated a Monte
Carlo simulation. The fair value of the Silver Stream derivative liability is a Level 3 measurement. The key inputs to calculate the fair value of the silver stream derivative
liability at each reporting date include:

●
●
●
●
●
●
●

COMEX spot silver price;
COMEX silver futures curve;
COMEX 4-year at-the-money silver implied volatility;
USD 3-month LIBOR discount curve;
First Mining’s estimated credit spread;
Probability of receiving future advanced payments; and
Quarterly delivery schedule of payable silver (updated for the recently completed Pre-Feasibility Study).

The  fair  value  of  the  Silver  Stream  derivative  liability  is  calculated  at  each  reporting  date  as  the  net  of  the  future  Advance  Payment  tranches  receivable  (an  asset  for  the
Company) and the Silver Stream obligation (a liability to the Company), with gains and losses recorded in the statement of net loss and comprehensive income (loss). The fair
value of the Silver Stream derivative liability at July 2, 2020 was determined to be US$5,431,000 ($7,378,000), which consisted of the fair value of the Advance Payment
tranches yet to be received of US$8,473,000 ($11,512,000), net of the fair value of the future Silver Stream obligation of US$13,904,000 ($18,890,000). At December 31,
2020 the fair value of the Silver Stream derivative liability is US$10,415,000 ($13,260,000), which is comprised of the Silver Stream obligation fair value of US$21,761,000
($27,706,000) less the Advance Payment receivable fair value of US$11,346,000 ($14,446,000).

The fair value of the 30 million common share purchase warrants issued to First Majestic as part of the transaction was calculated using the Black-Scholes option pricing
model. The fair value of the warrants of $6,278,000 was recorded in Equity (Warrant reserve) on the Company’s consolidated statements of financial position. The Company
measured the transaction date fair value using the following Black-Scholes assumptions:

Risk-free interest rate
Expected life (years)
Expected volatility(1)
Expected dividend yield

July 2,
2020

0.38%

5.00 years 

70.65%
Nil 

(1)   The computation of expected volatility was based on the Company’s historical price volatility, over a period which approximates the expected life of the warrant.

Other  mineral  properties  in  Canada  as  at  December  31,  2020  and  December  31,  2019  include  the  mining  claims  and  concessions  located  in  the  Township  of
Duparquet, Quebéc, which are near the Company’s Duquesne gold project. Other mineral properties in Canada as at December 31, 2020 also include the 1.5% NSR
Royalty under the terms of the Treasury Share Purchase Agreement (Note 4), which was reclassified from “Goldlund” to “Others” during the year ended December
31, 2020.

The Company has various underlying agreements and commitments with respect to its mineral properties, which define annual or future payments in connection with
royalty buy-backs or maintenance of property interests.

8. MINERAL PROPERTIES (Continued)

a)

Pickle Crow Project

On March 12, 2020, the Company and Auteco executed a definitive Earn-In Agreement (the “Earn-In Agreement”) whereby Auteco may earn up to an 80% interest in PC
Gold, a wholly-owned subsidiary of First Mining which owns the Pickle Crow Project. Pursuant to the Earn-In Agreement, the Earn-In is comprised of two stages:

● Stage 1 Earn-In (51% earn-in) – Three-year initial earn-in period to acquire a 51% equity interest in PC Gold by:

o Spending  $5,000,000  on  exploration  and  environmental  matters  at  the  Pickle  Crow  Gold  Project  (or  cash  payments  in  lieu),  of  which  $750,000  must  be  incurred

within the first 12 months; and

o Issuing 100 million shares of Auteco to First Mining.

● Stage 2 Earn-In (additional 19% to earn-in to 70%) – Upon completion of the Stage 1 Earn-In, Auteco will have a two-year follow-on period to acquire an additional

19% equity interest in PC Gold by:

o Spending a further $5,000,000 on exploration on the Pickle Crow Gold Project;
o Making a $1,000,000 cash payment to First Mining within 90 days of completing the additional exploration spend; and
o Issuing First Mining a 2% NSR royalty on the Project (1% of which can be bought back for USD$2,500,000) (issued upon completion of the Stage 2 Earn-In).

In  addition,  upon  completion  of  the  Stage  2  Earn-In,  Auteco  will  have  an  option  to  acquire  an  additional  10%  equity  interest  in  PC  Gold,  exercisable  any  time  following
completion of the Stage 2 Earn-In, by paying First Mining $3,000,000 in cash. First Mining’s residual 20% interest in the project is carried until a construction decision at
Pickle Crow, which is to be made after a final feasibility study and following Auteco having arranged sufficient financing to achieve commercial production. If Auteco should
fail to meet such requirements within the applicable time periods, the Earn-In Agreement will terminate and Auteco will be entitled to retain any interest which it has earned-
in to prior to the date of termination. During the term of the Earn-In Agreement, Auteco will incur all program costs and manage Pickle Crow exploration activity.

During  the  year  ended  December  31,  2020,  the  Company  received  the  scheduled  consideration  in  cash  of  $100,000  and  25  million  shares  of  Auteco  with  a  fair  value  on
receipt of $740,000 under the terms of the Earn-in Agreement. Auteco incurred a total of $3,570,000 in exploration expenditures during the year ended December 31, 2020.

As the Earn-In Agreement provides Auteco the right to earn an interest in PC Gold, rather than a direct interest in the Pickle Crow project, Auteco’s option to acquire PC Gold
shares is a financial liability of First Mining. As a derivative, the Option – PC Gold liability is classified as FVTPL.

As there is no observable market data which can be used to determine the fair value of the Option – PC Gold liability, management uses property specific and market-based
information to determine whether a significant change in the fair value of the option liability has occurred. Factors that are considered include:

● Performance of the Auteco share price;
● The amount or timing of Pickle Crow exploration expenditures incurred;
● Updates to the NI 43-101 resource report (or Australian equivalent);
● Milestone payment probability assumptions; and
● Gold spot prices over the period from the Earn-In Agreement closing to December 31, 2020.

8. MINERAL PROPERTIES (Continued)

As  at  December  31,  2020,  management  has  estimated  a  fair  value  for  the  Option  –  PC  Gold  liability  of  $4,410,000.  Management  has  concluded  that  there  were  no
developments in the period since inception that would indicate a material change in fair value and, accordingly, the Option – PC Gold liability remains recorded at the amount
received from the counterparty. These amounts include cash, exploration expenditures incurred and the value, at the time of receipt, of the 25 million Auteco shares received.

b)

Cameron Gold Project

On  December  9,  2020,  the  Company  and  Metalore  Resources  Limited  (“Metalore”)  completed  a  transaction  (“Metalore  Transaction”)  pursuant  to  which  First  Mining
acquired the East Cedartree claims from Metalore, filling in a strategic landholding which is contiguous to the Cameron Gold Project. Under the Metalore Transaction, as
consideration for the acquisition of the East Cedartree claims, First Mining paid Metalore $3,000,000 in cash and issued 3,000,000 shares of First Mining with a fair value of
$1,215,000.

c)

Mexican Property Portfolio

Mineral properties in Mexico as at December 31, 2019 included Miranda, Socorro, San Ricardo, Las Margaritas, Puertecitos, Los Tamales, Geranio, El Apache, El Roble,
Batacosa and Lachatao. On April 28, 2020, the Company entered into a share purchase agreement with a third-party private company (the “Purchaser”) pursuant to which the
Purchaser acquired all of the issued and outstanding shares of 0924682 B.C. Ltd. and 1089568 B.C. Ltd., two wholly-owned subsidiaries of the Company that held all of the
shares of two Mexican subsidiaries which owned all of the Company’s Mexican mineral properties. Consideration consisted of a nominal amount of cash, and the grant to the
Company of a 2% NSR on 10 of the 11 Mexican mineral properties. Following the date of this sales agreement, First Mining no longer holds any subsidiaries or mineral
properties in Mexico. The transaction resulted in a $303,000 loss on disposal of subsidiaries which was recorded on the statement of net loss and comprehensive income (loss)
for the year ended December 31, 2020, and the resultant recycling of currency translation adjustment on disposal of the Mexican subsidiaries amounting to $616,000.

9. MINERAL PROPERTY INVESTMENTS

The Company, through its subsidiary Clifton Star Resources Inc. (“Clifton”), has a 10% equity interest in the shares of Beattie Gold Mines Ltd., 2699681 Canada Ltd., and
2588111 Manitoba Ltd which directly or indirectly own various mining concessions and surface rights, collectively known as the Duparquet gold project.

Mineral property investments (which comprise equity interests in the shares of three private companies) are designated as FVTOCI, with changes in fair value recorded in
other comprehensive income (loss).

As there is no observable market data which can be used to determine the fair value of the Company’s mineral property investments, management uses property specific and
market-based information to determine whether a significant change in the fair value of these investments has occurred. Factors that are considered include:

● Changes in the economic and regulatory environment for the jurisdiction in which the Duparquet Gold project is located;
● Gold spot prices over the period from the acquisition of the investment to December 31, 2020;
● The Company’s market capitalization per in-situ ounce which are attributable to the Duparquet Gold project; and
● Recent transactions involving mineral properties located in Quebec.

9. MINERAL PROPERTY INVESTMENTS (Continued)

During the year ended December 31, 2020, management determined, as a function of the rising gold price environment, that there was an increase in the fair value of mineral
property investments and a fair value gain of $1,329,000 was recorded during the year ended December 31, 2020 (year ended December 31, 2019 - $981,000) (Note 20). As
at December 31 2020, the fair value of the Company’s mineral property investments is $6,726,000 (December 31, 2019 - $5,398,000).

10. RIGHT-OF-USE ASSET AND LEASE LIABILITY

In  December  2019,  the  Company  entered  into  a  5-year  lease  agreement  to  use  Vancouver  office  space.  At  the  commencement  date  of  the  lease,  the  lease  liability  was
measured  at  the  present  value  of  the  lease  payments.  The  lease  payments  are  discounted  using  an  interest  rate  of  10%,  which  is  the  Company’s  estimated  incremental
borrowing rate.

The  Company  has  an  obligation  to  undertake  decommissioning,  restoration,  rehabilitation  and  environmental  work  when  environmental  disturbance  is  caused  by  the
exploration and development of a mineral property. As at December 31, 2020, the Company estimates that the fair value of the environmental reclamation provision for the
Pickle  Crow  Gold  Project,  in  Ontario,  is  $3,383,000  (December  31,  2019  -  $2,355,000).  The  liability  was  estimated  based  on  management’s  interpretation  of  current
regulatory requirements and is recognized at the present value of such costs. The amount is recorded in the “Assaying, field supplies, and environmental” category in Mineral
Properties per Note 8. The undiscounted balance of the estimated cash flows is $3,190,000 in 2020 dollars. The recorded amount has been measured using a risk-free discount
rate of between 0.20% and 0.60% based on Canadian government bonds with associated maturities which match the estimated cash outflows and using an inflation rate of 2%
per year. The cash outflows in respect of the provision are estimated to occur over the next eleven years.

On August  26,  2020,  the  Company  closed  a  bought  deal  offering  (the  “August  Offering”).  Pursuant  to  the  August  Offering,  the  Company  issued  57,500,000  units  of  the
Company (the “Bought Deal Units”) at a price of $0.50 per Bought Deal Unit for gross proceeds of $28,750,000. In connection with the August Offering, the Company paid
issuance costs of $2,073,000 in cash, including professional fees, underwriters’ commission, and underwriters’ legal fees. Each Bought Deal Unit consists of one common
share  of  the  Company  and  one-half  of  one  common  share  purchase  warrant  (each  whole  common  share  purchase  warrant,  a  “Bought  Deal  Warrant”).  Each  Bought  Deal
Warrant  entitles  the  holder  to  acquire  one  common  share  of  the  Company  for  a  period  of  24  months  following  the  closing  of  the  August  Offering  at  a  price  of  $0.70.  An
amount  of  $23,518,000  ($25,339,000  net  of  allocated  issuance  costs  of  $1,821,000)  was  recorded  in  share  capital.  The  Bought  Deal  Warrants  were  valued  at  $3,159,000
($3,411,000 net of allocated issuance costs of $252,000) using the relative fair value method.

Non-Brokered Private Placement Financing

On March 6, 2020, the Company completed a non-brokered private placement raising aggregate gross proceeds of $8,532,000 (the “March Offering”). Pursuant to the March
Offering, the Company issued an aggregate of 27,420,318 units of the Company (the “Units”) at a price of $0.22 per Unit for gross proceeds of $6,032,000 and 10,000,000
flow-through units of the Company (the “FT Units”) at a price of $0.25 per FT Unit for gross proceeds of $2,500,000. In connection with the March Offering, the Company
paid  issuance  costs  of  $158,000  in  cash.  Each  Unit  consisted  of  one  common  share  of  the  Company  and  one-half  of  one  common  share  purchase  warrant  (each  whole
common share purchase warrant, a "Warrant"). Each Warrant entitles the holder to acquire one common share of the Company for a period of 36 months from the date of
issuance  at  a  price  of  $0.33.  Each  FT  Unit  consisted  of  one  flow-through  common  share  of  the  Company  that  qualifies  as  a  "flow-through  share"  for  the  purposes  of  the
Income Tax Act (Canada) (the “ITA”) and one-half of one Warrant on the same terms as the Warrants forming part of the Units. An amount of $7,274,000 ($7,410,000 net of
allocated issuance costs of $136,000) was recorded in share capital. The Warrants were valued at $1,100,000 ($1,122,000 net of allocated issuance costs of $22,000) using the
relative fair value method, and the remaining $300,000, representing the implied premium, was recorded as a flow-through share premium liability (Note 14).

Private Placement Equity Financing with Ausenco

First Mining has entered into an agreement with Ausenco Engineering Canada Inc. (“Ausenco”) to complete a PFS for the Company’s Springpole Gold Project. Ausenco or
an  affiliate  will  be  entitled  to  receive  approximately  $1,600,000  in  fees  thereunder.  Pursuant  to  the  agreement  with  Ausenco,  on  January  15,  2020  the  Company  closed  a
private placement with Ausenco, for gross cash proceeds of approximately $750,000 in respect of its subscription for common shares (the “Ausenco Offering”). Pursuant to
the Ausenco Offering, First Mining issued 2,777,777 common shares to Ausenco at a price of $0.27 per common share. First Mining then prepaid $750,000 to Ausenco for
the first tranche of work under the PFS, and these services were provided to the Company in full during the year ended December 31, 2020.

ATM distributions

On  August  20,  2019,  First  Mining  announced  it  had  entered  into  an  at‐the‐market  ("ATM")  equity  distribution  agreement  with  Cantor  Fitzgerald  Canada  Corporation
(“Cantor”) as agent pursuant to which First Mining may, at its discretion and from time‐to‐time, sell up to $15.0 million of common shares of the Company to the public at
the prevailing market price of the Company’s common shares on the TSX at the time of such sale. The sale of these common shares will be made through “at‐the‐market
distributions” as defined in the Canadian Securities Administrators’ National Instrument 44‐102 Shelf Distributions, including sales made directly on the TSX, or any other
recognized marketplace upon which the Company’s common shares are listed or quoted or where the common shares are traded in Canada. During the year ended December
31, 2020, First Mining sold 532,000 common shares of the Company under the ATM program at an average price of $0.24 per common share for gross proceeds of $129,000,
or net proceeds of $125,000 after deducting the commission of $4,000 paid to Cantor in respect of these ATM sales.

Certain stock options granted were directly attributable to exploration and evaluation expenditures on mineral properties and were therefore capitalized to mineral properties.
In addition, certain stock options were subject to vesting provisions. These two factors result in differences between the aggregate fair value of stock options granted and total
share-based  payments  expensed  during  the  periods.  Total  share-based  payments  expense  during  the  years  ended  December  31,  2020  and  2019  was  classified  within  the

19. SUPPLEMENTAL CASH FLOW INFORMATION

During the year ended December 31, 2020, the significant non-cash investing and financing transactions were as follows:

● 24,220 shares issued with a value of $4,000 in connection with a previous mineral property acquisition;
● 3,000,000 shares issued with a value of $1,215,000 in connection with acquisition of the East Cedartree claims (Note 8); and
● Received 25 million shares of Auteco with a fair value of $740,000 in connection with the Earn-In Agreement (Note 8(a)), 805,698 shares of First Majestic with a fair
value of $10,394,000 in connection with the Silver Purchase Agreement (Note 5), 43.33 million shares of Treasury Metals with a fair value of $78,000,000 and 11.67
million Treasury Metals Warrants with a fair value of $9,812,000 in connection with the Treasury Share Purchase Agreement (Note 4).

During the year ended December 31, 2019, significant non-cash investing and financing transactions were as follows:

● 370,250 shares issued as finder’s fee in connection with December 18, 2019 private placement (Note 13); and
● Received 1,217,532 shares of Gainey Capital Corp. with a fair value of $171,000 under the terms of the option agreement with Gainey Capital Corp.

20. FAIR VALUE

Fair values have been determined for measurement and/or disclosure requirements based on the methods below.

The Company characterizes fair value measurements using a hierarchy that prioritizes inputs depending on the degree to which they are observable. The three levels of the
fair value hierarchy are as follows:

●
●

●

Level 1: fair value measurements are quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2: fair value measurements are those derived from inputs other than quoted prices included within level 1 that are observable for the asset or liability, either
directly (i.e. as prices) or indirectly (i.e. derived from prices); and
Level  3:  fair  value  measurements  are  those  derived  from  valuation  techniques  that  include  significant  inputs  for  the  asset  or  liability  that  are  not  based  on
observable market data (unobservable inputs).

The carrying values of cash and cash equivalents, current accounts receivables, and accounts payable and accrued liabilities approximated their fair values because of the
short-term nature of these financial instruments. These financial instruments are classified as financial assets and liabilities at amortized cost.

The carrying value of the non-current reclamation deposit approximated its fair values as the amount is represented by a cash deposit. This financial instrument is classified as
a financial asset at amortized cost.

The carrying value of investments (except for Treasury Metals Warrants) were based on the quoted market prices of the shares as at December 31, 2020 and was therefore
considered to be Level 1. The fair value of Treasury Metals Warrants is determined using certain Level 2 inputs, as the Black-Scholes valuation model incorporates Treasury
Metals’ share price volatility.

20. FAIR VALUE (Continued)

The mineral property investments (First Mining’s 10% equity interest in three privately held companies that own the Duparquet Gold Project) are classified as financial assets
at FVTOCI. The fair value of the mineral property investments was not based on observable market data and was therefore considered to be Level 3. The initial fair value of
the mineral property investments was determined based on attributable pro-rata gold ounces for the Company’s 10% indirect interest in the Duparquet project, which formed
part of the identifiable assets from the acquisition of Clifton. Subsequently, the fair value has been reassessed at each period end. Scenarios which may result in a significant
change in fair value include, among others, a change in the performance of the investee, a change in the performance of comparable entities, a change in gold price, a change
in the economic environment, or evidence from external transactions in the investee’s equity. During the year ended December 31, 2020, management concluded that there
was an increase in the fair value of the mineral property investments, and a fair value gain of $1,329,000 (December 31, 2019 - $981,000) was recorded (Note 9).

As the Earn‐In Agreement provides Auteco the right to earn an interest in PC Gold, rather than a direct interest in the Pickle Crow project, Auteco’s option to acquire PC
Gold shares is a financial liability of First Mining. As a derivative, the Pickle Crow project option liability is classified as financial liability at FVTPL. The carrying value of
the Option - Pickle Crow Gold Project was not based on observable market data and involved complex valuation methods and was therefore considered to be Level 3. The
initial fair value of the Option – Pickle Crow Gold Project was determined based on initial consideration in cash of $100,000, 25 million shares of Auteco with a fair value
upon receipt of $740,000 and exploration expenditures incurred by Auteco under the terms of the Earn-in Agreement. Scenarios which may result in a significant change in
fair value include, among others, performance of the Auteco share price, the amount or timing of Pickle Crow exploration expenditures incurred or updates to the NI 43-101
(or Australian equivalent) resource report. During the year ended December 31, 2020, management concluded that there was no significant change in the fair value of the
Option – PC Gold liability.

The Silver Stream was determined to be a derivative liability, which is classified as a financial liability at FVTPL. The carrying value of the derivative liability was not based
on observable market data and involved complex valuation methods and was therefore considered to be Level 3.

21. FINANCIAL AND CAPITAL RISK MANAGEMENT

The  Company  thoroughly  examines  the  various  financial  instruments  and  risks  to  which  it  is  exposed  and  assesses  the  impact  and  likelihood  of  those  risks.  These  risks
include market risk (including equity price risk, foreign currency risk, interest rate risk and commodity price risk), credit risk, liquidity risk, and capital risk. Where material,
these risks are reviewed and monitored by the Board of Directors.

21. FINANCIAL AND CAPITAL RISK MANAGEMENT (Continued)

The Board of Directors has overall responsibility for the determination of the Company’s risk management objectives and policies. The overall objective of the Board is to set
policies that seek to reduce risk as far as possible without unduly affecting the Company’s competitiveness and flexibility.

a) Market Risk

Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate due to changes in market prices. Market risk includes equity price risk,
foreign currency risk, interest rate risk and commodity price risk.

Equity Price Risk

The  Company  is  exposed  to  equity  price  risk  as  a  result  of  holding  investments  in  equity  securities,  which  are  comprised  of  marketable  securities  and  mineral  property
investments, in other mineral property exploration companies.

If the fair value of our investments in equity instruments designated as FVTPL had been 10% higher or lower as at December 31, 2020, net loss for the year ended December
31, 2020 would have decreased or increased, respectively, by approximately $1,504,000 (2019 – $nil), as a result of changes in the fair value of equity investments. If the fair
value of our investments in equity instruments designated as FVTOCI had been 10% higher or lower as at December 31, 2020, other comprehensive income (loss) for the year
ended December 31, 2020 would have decreased or increased, respectively, by approximately $1,011,000 (2019 – $717,000), as a result of changes in the fair value of equity
investments.

Foreign Currency Risk

The Company is exposed to the financial risk related to the fluctuation of foreign exchange rates. During the first half of 2020, the Company operated in Canada and the
United States, and a portion of the Company’s expenses were incurred in Canadian dollars (“CAD”), and US dollars (“USD”). A significant change in the currency exchange
rates between the Canadian and US currencies could have an effect on the Company’s results of operations, financial position or cash flows. As at December 31, 2020, the
Company held USD denominated cash and cash equivalents of $5,567,000. The Company has not hedged its exposure to currency fluctuations.

 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
   
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
   
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
Interest Rate Risk

Interest rate risk is the risk that future cash flows will fluctuate as a result of changes in market interest rates. The Company does not have any borrowings that are subject to
fluctuations in market interest rate. Interest rate risk is limited to potential decreases on the interest rate offered on cash and cash equivalents held with chartered Canadian
financial institutions. The Company manages its interest rate risk by seeking to optimize the interest income earned on excess funds while maintaining the necessary liquidity
to conduct its day-to-day operations. The Company considers this risk to be immaterial.

(Expressed in Canadian dollars unless otherwise noted, tabular amounts are expressed in thousands of Canadian dollars)

21. FINANCIAL AND CAPITAL RISK MANAGEMENT (Continued)

Commodity price risk

The Company is subject to commodity price risk from fluctuations in the market prices for silver. Commodity price risks are affected by many factors that are outside the
Company’s  control  including  global  or  regional  consumption  patterns,  the  supply  of  and  demand  for  metals,  speculative  activities,  the  availability  and  costs  of  metal
substitutes, inflation, and political and economic conditions. The financial instrument impacted by commodity prices is the Silver Stream derivative liability.

b) Credit Risk

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. Financial instruments
which are potentially subject to credit risk for the Company consist primarily of cash and cash equivalents, accounts and other receivables, and the reclamation deposit. The
Company considers credit risk with respect to its cash and cash equivalents to be immaterial as cash and cash equivalents are mainly held through high credit quality major
Canadian financial institutions as determined by ratings agencies.

c) Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company’s policy is to ensure that it will have sufficient
cash  to  allow  it  to  meet  its  liabilities  when  they  become  due,  under  both  normal  and  stressed  conditions,  without  incurring  unacceptable  losses  or  risking  damage  to  the
Company’s  reputation.  The  Company  manages  its  liquidity  risk  by  preparing  annual  estimates  of  exploration  and  administrative  expenditures  and  monitoring  actual
expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.

The following table summarizes the maturities of the Company’s financial liabilities as at December 31, 2020 based on the undiscounted contractual cash flows:

hand to meet operating requirements as they arise for at least the next 12 months.

d) Capital Risk Management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to pursue the exploration and retention of its
mineral properties. The Company has historically demonstrated the ability to raise new capital through equity issuances and/or through surplus cash as part of its acquisitions.
In  the  management  of  capital,  the  Company  includes  the  components  of  shareholders’  equity  as  well  as  cash.  The  Company  prepares  annual  estimates  of  exploration  and
administrative expenditures and monitors actual expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

2020 HIGHLIGHTS

The following highlights the Company’s developments during fiscal 2020 (including subsequent events up to March 24, 2021).

Project Highlights

Springpole

● Announced results of a positive Pre-Feasibility Study (“PFS”) in January 2021. Post-tax net present value at a 5% discount rate (“NPV5%”) of US$995 million, post-

tax internal rate of return (“IRR”) of 29% and post-tax payback of 2.4 years on initial capital of US$718 million.

● Completed a silver stream transaction with First Majestic Silver Corp. (“First Majestic”) pursuant to which First Majestic will pay a total of US$22.5 million to the
Company, over three stages, for the right to purchase 50% of the payable silver produced from the Springpole Gold Project (US$17.5 million received to date).
● Progressed environmental fieldwork throughout 2020 and submitted the amended proposed Terms Of Reference to the Ontario Ministry (MECP) in April 2021, with

anticipated completion in May 2021.

● Continued engagement with local indigenous rights holders and stakeholders of the Springpole Gold Project.
● Filed the technical report for the PFS on the Springpole Gold Project filed on SEDAR in March 2021. The report, entitled “NI 43-101 Technical Report and Pre-
Feasibility  Study  on  the  Springpole  Gold  Project,  Ontario  Canada”  and  dated  February  26,  2021,  was  prepared  by  AGP  Mining  Consultants  Inc.  (“AGP”)  in
accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and is available under First Mining’s SEDAR profile at
www.sedar.com.

Cameron

● Acquired the East Cedartree claims from Metalore Resources Limited (“Metalore”) in December 2020, thereby consolidating First Mining’s land holdings in the
area into a single contiguous block and adding a further 3,200 hectares to the 49,574 hectares that the Company already held in the area. In connection with this
acquisition, First Mining paid $3.0 million in cash to Metalore, and issued 3 million common shares of First Mining (“First Mining Shares”) to Metalore (with such
shares subject to a statutory hold period of four months plus one day from the closing date of the transaction).

Pickle Crow

● Auteco  completed  the  spend  requirements  for  the  Stage  1  51%  earn-in  in  March  2021  and  will  operate  under  a  formal  Joint  Venture  in  April  2021  following  its
shareholder meeting to approve the issuance of 100 million Auteco shares. At the closing of Stage 1, First Mining will own 125 million Shares of Auteco with a
current value of approximately $10.6 million. Auteco is continuing its project spend to earn-in to 80% of the Project with four drill rigs currently operating at site.
The Company also has the right to a 2% net smelter returns (“NSR”), 1% of which can be bought back for US$$2.5 million.

Goldlund

● Sold  the  Goldlund  gold  project  (“Goldlund”)  to  Treasury  Metals  Inc.  (“Treasury Metals”)  in  August  2020.  First  Mining  currently  owns  43.3  million  shares  of
Treasury  Metals  and  11.67  million  warrants  of  Treasury  Metals  with  an  exercise  price  of  $1.50.  As  part  of  the  transaction,  First  Mining  also  owns  a  1.5%  NSR
royalty  on  the  Goldlund  gold  project,  of  which  0.5%  can  be  bought  back  by  Treasury  Metals  by  paying  First  Mining  $5.0  million  in  cash.  In  addition,  Treasury
Metals is to pay First Mining a milestone cash payment of $5.0 million, with $2.5 million payable upon receipt of a final and binding mining lease to extract ore from
an open pit mine at Goldlund, and $2.5 million payable upon the extraction of 300,000 tonnes of ore from a mine at Goldlund.

COVID-19 Response

In response to the onset of the COVID-19 novel coronavirus (“COVID-19”) pandemic, the Company adopted a series of robust COVID-19 risk mitigation policies
incorporating recommendations set by the provincial Governments of Ontario and British Columbia, and by the Government of Canada. To date, First Mining has not had any
cases of COVID-19 at any of the camp operations at its projects or its head office in Vancouver. The health and safety of First Mining’s workforce, their families and the
communities in which the Company operates is First Mining’s primary concern. In the interests of the health and well-being of its employees, contractors, visitors to its office
and operations, and the families of all such persons, First Mining implemented a work from home policy for its employees in March 2020. First Mining is committed to fully
supporting safety measures for its workforce, families and communities.

At Springpole, the Company initially demobilized one of its two drill crews in early March 2020. In order to ensure the health and safety of all its employees, the Company
had intended to complete the shift rotation while limiting access to site for any new individuals. Work at site was nearing completion ahead of a planned reduction in on-site
activities until after the spring ice break-up. However, due to the COVID-19 pandemic, First Mining decided to demobilize the remaining contractors and staff at Springpole
in the last week of March 2020, and to keep the project on care and maintenance until it was able to restart its work programs.

On May 28, 2020, the Company announced the restart of field operations at the Springpole Gold Project, which have been ongoing since then. First Mining continues to
monitor the COVID-19 situation very closely and will adapt technical work programs as the situation evolves.

(1)   This represents mineral property expenditures per consolidated statements of cash flows.
(2)   This is a non-IFRS measurement with no standardized meaning under IFRS and may not be comparable to similar financial measures presented by other issuers. For

further information please see the section in this MD&A titled “Non-IFRS Measures”.

(3)   The basic and diluted loss per share calculations result in the same amount due to the anti-dilutive effect of outstanding stock options and warrants.

Net Loss - Fluctuations in net loss are typically caused by non-cash items. Removing the impact of these illustrates that the income statement loss on operational activities is
relatively consistent over the years presented at an average of approx. $4.5 million.

Cash  and  Cash  Equivalents  - the  increase  in  2020  was  primarily  attributable  to  cash  raised  from  financing  activities  during  the  year,  partially  offset  by  cash  used  in
operational  activities  (Statement  of  Net  Loss)  and  investing  activities  at  the  projects  (Statement  of  Financial  Position).  See  ‘Financial  Condition,  Liquidity  and  Capital
Resources’ section in this MD&A.

Total Assets – increased  mainly  due  to  the  increases  in  current  assets,  being  the  net  cash  and  cash  equivalent  increases  noted  above  and  the  fair  value  balances  of  First
Mining’s  investments  reflecting  shares  and  warrants  held  by  the  Company  in  third  party  companies.  Non-current  assets  decreased  during  the  year  as  a  result  of  non-cash
impairments resulting from the sale of Goldlund to the Treasury Metals and the resultant reclassification of mineral property holdings for accounting purposes.

The Mineral Reserve estimate has an effective date of December 30, 2020 and is based on the Mineral Resource estimate that has an effective date of July 30,
2020.
The Mineral Reserve estimate was completed under the supervision of Gordon Zurowski, P.Eng., of AGP, a Qualified Person as defined under NI 43-101.
Mineral Reserves are stated within the final design pit based on a US$878/oz Au pit shell with a US$1,350/oz Au price for revenue.
The equivalent cut-off grade was 0.34 g/t gold (“Au”) for all pit phases.
The mining cost averaged $1.94/t mined, processing cost averaged $14.50/t milled, and the G&A cost averaged $1.06/t milled. The process recovery for gold
averaged 88% and the silver recovery was 93%.
The exchange rate assumption applied was $1.30 equal to US$1.00.

CANADIAN GOLD PROJECTS

Springpole Gold Project, Ontario

The Springpole Gold Project covers an area of 41,943 hectares in northwestern Ontario, consisting of 30 patented mining claims, 435 contiguous mining claims and thirteen
mining  leases.  The  project  is  located  approximately  110  kilometres  (“km”)  northeast  of  the  Municipality  of  Red  Lake  in  northwestern  Ontario  and  is  situated  within  the
Birch-Uchi Greenstone Belt. The large, open pittable resource is supported by significant infrastructure, including a 72-person onsite camp, winter road access, a logging road
and nearby power lines within 40 km. The Springpole Gold Project is located within an area that is covered by Treaty Three and Treaty Nine First Nations Agreements. With
approximately 4.7 million ounces of gold and 24 million ounces of silver in the indicated resource category, Springpole Gold Project is one of the largest undeveloped gold
projects in Ontario1.

During the year ended December 31, 2020, the most significant expenditures at the Springpole Gold Project were:

● $1,664,000 in connection with hydrogeology, geotechnical and metallurgical drilling;
● $1,593,000 in connection with the pre-feasibility study;
● $1,059,000 for site employees’ salaries and management salary allocations;
● $871,000 in connection with the continuation of environmental permitting and associated fieldwork; and
● $740,000 in connection with concessions and advanced royalty payments.

During the year ended December 31, 2020, and up to the date of this report in 2021, the most significant operational developments at the Springpole Gold Project were:

1.

Completion of Pre-Feasibility Study

The PFS for the Springpole Gold Project evaluates recovery of gold and silver from a 30,000 tonne-per-day (“tpd”) open pit operation, with a process plant that will include
crushing, grinding, and flotation, with fine grinding of the flotation concentrate and agitated leaching of both the flotation concentrate and the flotation tails followed by a
carbon-in-pulp recovery process to produce doré bars.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

The mineral resources defined in the PFS do not reflect the significant opportunities that are available for resource expansion or discovery of additional ore bodies in the
Springpole  district.  First  Mining  believes  that  the  Springpole  Gold  Project  has  several  avenues  for  resource  expansion,  both  within  the  existing  property  footprint  and
regionally in the under-explored Birch Uchi Greenstone belt. First Mining plans to undertake a further 10,000 m of diamond drilling at the Springpole Gold Project in 2021
for metallurgy, exploration, condemnation, and geotechnical purposes, and will continue to review other exploration opportunities in the area.

Project Enhancement Opportunities

The PFS identified several opportunities to enhance the economics of the Springpole Gold Project, and they will be investigated as First Mining continues to advance the
project. These opportunities include:

● Existing Resource Upgrades. Inferred Mineral Resources are contained within the existing pit design, and with additional infill drilling, these resources may potentially
support conversion of some or all of this material into Indicated Mineral Resources that could be converted to Probable Mineral Reserves and evaluated in a Feasibility
Study (“FS”).

● Mine Plan Optimization. Refined pit optimization parameters could result in better optimized open pit limits which could reduce the overall strip ratio.
● Process Optimization. Continued efforts to investigate opportunities to improve the metal recoveries through further metallurgical testing and refining milling processes,

as well as other process optimizations.

● Further  Geotechnical  Studies.  A  better  hydrogeological  and  geotechnical  understanding  may  increase  pit  slope  angles,  potentially  reducing  costs  associated  with

mining waste material.

● Additional Mineralization. There  are  geophysical  targets  in  the  area  around  the  current  resource,  where  additional  drilling  has  the  potential  to  identify  additional

mineralization that could support Mineral Resource estimation with upside potential for the LOM.

2.

Silver Stream transaction with First Majestic Silver Corp.

On  June  10,  2020,  First  Mining  entered  into  a  Silver  Purchase  Agreement  with  First  Majestic  pursuant  to  which  First  Majestic  has  agreed  to  pay  First  Mining  total
consideration  of  US$22.5  million  (the  “Advance  Payment”),  in  the  following  three  tranches,  for  the  right  to  purchase  50%  of  the  payable  silver  produced  from  the
Springpole Gold Project for the life of the project (the “Silver Stream”):

● US$10 million payable on closing the transaction, with US$2.5 million payable in cash and the remaining US$7.5 million to be satisfied by the issuance to First

Mining of 805,698 common shares of First Majestic (the “First Majestic Shares”);

● US$7.5 million payable upon First Mining publicly announcing the completion of a positive PFS for the Springpole Gold Project, with US$3.75 million payable in
cash and US$3.75 million payable in First Majestic Shares based on the 20-day volume-weighted average trading price (“VWAP”) of the First Majestic Shares on
the TSX at the time; and

● US$5  million  payable  upon  First  Mining  receiving  approval  of  a  Federal  or  Provincial  Environmental  Assessment  for  the  Springpole  Gold  Project,  with  US$2.5

million payable in cash and US$2.5 million payable in First Majestic Shares (based on 20-day VWAP of the First Majestic Shares on the TSX at the time).

The transaction closed on July 2, 2020, and upon closing the transaction, First Mining granted 30 million common share purchase warrants of First Mining (“First Mining
Warrants”) to First Majestic pursuant to the terms of the Silver Purchase Agreement. Each First Mining Warrant entitles First Majestic to purchase one First Mining Share at
an exercise price of $0.40 for a period of five years.

As of the date of this MD&A, the first two cash and share payments set out above, totalling US$17.5 million, have been paid to First Mining by First Majestic.

In the event of default, First Majestic may terminate the Silver Purchase Agreement and the Advance Payment received by First Mining at that time would become repayable.

FIRST MINING GOLD CORP.
(Expressed in thousands of Canadian dollars, unless otherwise indicated)

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

Upon receipt of its share of silver production, First Majestic will make cash payments to First Mining for each ounce of silver paid to First Majestic under the Silver Purchase
Agreement equal to 33% of the lesser of the average spot price of silver for the applicable calendar quarter, and the spot price of silver at the time of delivery (the “Silver
Cash Price”), subject to a price cap of US$7.50 per ounce of silver (the “Price Cap”). The Price Cap is subject to annual inflation escalation of 2%, commencing at the start
of the third year of production. First Mining has the right to repurchase 50% of the Silver Stream for US$22.5 million at any time prior to the commencement of production at
Springpole.

The Silver Stream has an initial term of 40 years from July 2, 2020. The term is automatically extended by successive 10-year periods as long as the life of mine continues for
the Springpole Gold Project. If upon expiration of the term of the Silver Purchase Agreement, the Company has not sold to First Majestic an amount of silver sufficient to
reduce the Advance Payment to nil, then a refund of the uncredited balance, without interest shall be due and owing by the Company to First Majestic.

The proceeds received by First Mining are being used to advance the Springpole Gold Project through the PFS process and will also be used to advance the project through
the federal and provincial environmental assessment (“EA”) processes, in additional they will fund general corporate expenses.

For  accounting  purposes,  the  Company  has  concluded  that  the  Silver  Stream  is  a  standalone  derivative  measured  at  FVTPL.  As  of  the  acquisition  date,  the  estimated  fair
value of the Silver Stream derivative liability was determined using a discounted cash flow model which incorporated a Monte Carlo simulation. The fair value of the Silver
Stream derivative liability is calculated at each reporting date as the net of the future Advance Payment tranches receivable (an asset for the Company) and the Silver Stream
obligation (a liability to the company), with gains and losses recorded in the statement of net income (loss) and comprehensive income (loss). The fair value of the Silver
Stream derivative liability at July 2, 2020 was determined to be US$5,431,000 ($7,378,000), which consisted of the fair value of the Advance Payment tranches receivable of
US$8,473,000 ($11,512,000), net of the fair value of future Silver Stream obligation of US$13,904,000 ($18,890,000). At December 31, 2020, the fair value of the Silver
Stream is US$10,415,000 ($13,260,000), which consisted of fair value of the remaining Advance Payment tranches receivable of US$21,761,000 ($27,706,000) net of the fair
value of the Silver Stream obligation of US$11,346,000 ($14,446,000).

The fair value of the 30 million First Mining Warrants issued to First Majestic as part of the transaction was calculated using the Black-Scholes option pricing model. At
inception, the fair value of these warrants was $6,278,000.

3.

Environmental Permitting and Baseline Data

First  Mining  made  key  strategic  additions  to  its  Environment  and  Community  Relations  team  in  2020  to  ensure  that  we  have  properly  resourced  the  permitting  and
community relations work for the Springpole Gold Project. Steve Lines joined First Mining as Vice President, Environment and Community Relations on December 1, 2020,
and has already built an expert team at the Company with extensive experience in Ontario’s EA process. The team brings across significant experience from Greenstone Gold
Mines’ Hardrock project which was subject to the same federal and provincial EA process that is currently underway for Springpole, and they bring further permitting and
regulatory experience from similar in-lake open pit mines in Canada including the Meadowbank Gold Mine and Gahcho Kué Diamond Mine. First Mining believes that the
experience, expertise and relationships of Steve and his team will contribute significantly to the ongoing de-risking of the Springpole Gold Project.

First Mining has been actively collecting environmental baseline data necessary to support an EA for the Springpole Gold Project since 2010. The studies, both completed
and  ongoing,  are  focused  on  characterizing  all  relevant  biological  and  physical  components  of  the  aquatic  and  terrestrial  environments  that  may  be  impacted  by,  and  may
interact with, the project.

First  Mining  continues  to  advance  the  Springpole  Gold  Project  through  the  federal  and  provincial  EA  processes.  The  Company’s  goal  is  to  prepare  a  coordinated  EA
document  that  meets  the  federal  and  provincial  requirements.  Community  consultation  and  engagement  with  local  Indigenous  communities  and  other  stakeholders  is
important to First Mining and will remain on-going through the EA process.

First Mining plans to advance the development of the coordinated EA document in 2021 in accordance with the federal Environmental Impact Statement (“EIS”) Guidelines
and the provincial EA Terms of Reference.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

The Springpole permitting timeline is as follows:

The final EIS guidelines outline federal information requirements for the preparation of an EIS and were prepared after taking into consideration comments received from
federal departments, the Ontario provincial ministry, Indigenous groups and the general public. To meet the requirements of the EIS, the Company has already undertaken a
broad range of environmental baseline studies at the Springpole Gold Project to collect biophysical data, which includes fish community and habitat surveys, species at risk
surveys,  atmospheric  environment  surveys  as  well  as  surface,  groundwater  and  hydrology  surveys.  Currently,  the  Company  is  collecting  environmental  baseline  data  and
other information to prepare an EIS for Springpole Gold Project. The Company chose to continue to stay in the Canadian Environmental Assessment Act, 2012 permitting
process and not move to the newly enacted Impact Assessment Act process.

 For the three months and year ended December 31, 2020

Cameron Gold Project, Ontario

The Cameron Gold Project covers an area of 49,574 hectares in northern Ontario and comprises 24 patented claims, 1,790 mining claims, 4 mining leases, and 7 Licenses of
Occupation.  The  Cameron  Gold  Project  deposit  is  a  greenstone‐hosted  gold  deposit  and  the  mineralization  is  mainly  hosted  in  mafic  volcanic  rocks  within  a  northwest
trending  shear  zone  (Cameron  Lake  Shear  Zone)  which  dips  steeply  to  the  northeast.  A  technical  report  titled  “Technical  Report  on  the  Cameron  Gold  Deposit,  Ontario,
Canada”,  prepared  by  Optiro  Pty  Limited,  was  filed  by  the  Company  on  SEDAR  on  March  22,  2017,  and  is  available  under  the  Company’s  SEDAR  profile  at
www.sedar.com. There is year-round road access to the property from the nearby highway and power lines within 20 km.

During the year ended December 31, 2020, the most significant expenditures at the Cameron Gold Project were:

● $4,219,000 in connection with the East Cedartree claims acquisition;
● $113,000 for site employees’ salaries and management salary allocations; and
● $18,000 in connection with the ore sorting test work program.

On December 3, 2020, the Company entered into an asset purchase agreement with Metalore in connection with the acquisition by First Mining of the East Cedartree claims
from Metalore, and the transaction closed on December 9, 2020. Under the terms of the transaction, First Mining paid Metalore $3 million in cash and issued 3 million First
Mining Shares to Metalore. The East Cedartree claims contain an existing mineral resource estimate that was prepared in accordance with NI 43-101 and they encompass a
highly favourable geological setting for new gold discoveries in close proximity to the existing known deposits at the Company’s Cameron and West Cedartree properties.
The acquisition of the East Cedartree claims consolidates First Mining’s land holdings at Cameron into a single contiguous block and adds a further 3,200 hectares to the
49,574 hectares that First Mining already holds in the district. Accordingly, as a result of the acquisition of the East Cedartree claims, the Cameron Gold Project now covers
an area of 52,774 hectares and comprises 24 patented claims, 2,002 mining claims, 4 mining leases, and 7 Licenses of Occupation.

2021 plans at Cameron include 10,000 metres of drilling to extend local understanding and identify new drill targets on the project and in particular at the recently acquired
East Cedartree claims, plus continued local community consultations and ongoing environmental permitting activities.

Pickle Crow Gold Project, Ontario

The Pickle Crow Gold Project covers an area of 19,033 hectares and comprises 104 patented claims and 932 mining claims. The area is located in northwestern Ontario and is
covered  by  the  Treaty  Nine  First  Nations  Agreement.  A  technical  report  titled  “An  Updated  Mineral  Resource  Estimate  for  the  Pickle  Crow  Property,  Patricia  Mining
Division,  Northwestern  Ontario,  Canada”,  prepared  by  Micon  International  and  dated  June  15,  2018,  was  filed  by  the  Company  on  SEDAR  on  August  23,  2018,  and  is
available under the Company’s SEDAR profile at www.sedar.com. Extensive infrastructure in place or proximal to the Pickle Crow Gold Project includes a 200 tpd gravity
mill on site, generators and fuel storage and gravel road access to the property, and the property is within 10 km of a regional airport at Pickle Lake. The Pickle Crow Gold
Project was a former high-grade operating mine until the late 1960s.

During the year ended December 31, 2020, the most significant expenditures at the Pickle Crow Gold Project were:

● $3,570,000 in exploration expenditures predominantly incurred by Auteco under the terms of the Earn-in Agreement;
● $45,000 for site employees’ salaries and management salary allocations; and
● $21,000 in mineral land taxes.

Earn-In Agreement with Auteco Minerals

On March 12, 2020, the Company and Auteco executed a definitive Earn-In Agreement, pursuant to which Auteco may complete the Earn-In relating to the Pickle Crow Gold
Project.  Under  the  terms  of  the  Earn-In  Agreement,  Auteco  can  earn  a  full  80%  equity  interest  in  PC  Gold  and  will  incur  all  program  costs  and  manage  Pickle  Crow
exploration activity.

Pursuant to the Earn-In Agreement, the Earn-In is comprised of two stages:

● Stage 1 Earn-In (51% earn-in) – Three-year initial earn-in period to acquire a 51% equity interest in PC Gold by:

o Spending  $5,000,000  on  exploration  and  environmental  matters  at  the  Pickle  Crow  Gold  Project  (or  cash  payments  in  lieu),  of  which  $750,000  must  be  incurred

within the first 12 months; and

o Issuing 100 million shares of Auteco to First Mining.

● Stage 2 Earn-In (additional 19% to earn-in to 70%) – Upon completion of the Stage 1 Earn-In, Auteco will have a two-year follow-on period to acquire an additional

19% equity interest in PC Gold by:

o Spending a further $5,000,000 on exploration at the Pickle Crow Gold Project;
o Making a $1,000,000 cash payment to First Mining within 90 days of completing the additional exploration spend; and
o Issuing First Mining a 2% NSR royalty on the Pickle Crow Gold Project (1% of which can be bought back by Auteco for US$2,500,000) (this NSR will be issued to

First Mining upon completion of the Stage 2 Earn-In).

During the year ended December 31, 2020, the Company received the scheduled cash consideration of $100,000 and 25 million shares of Auteco with a fair value on receipt
of  $740,000  under  the  terms  of  the  Earn-in  Agreement.  Subsequent  to  December  31,  2020,  Auteco  confirmed  to  the  Company  that  it  has  incurred  the  stage  1  earn-in
exploration spend of $5,000,000. Auteco will hold a meeting of its shareholders in April 2021 to approve the issuance of 100,000,000 Auteco shares to First Mining, and it
will apply to the Australian Securities Exchange (the “ASX”) for listing approval for such shares. First Mining expects to receive the 100,000,000 Auteco shares by the end of
April 2021, and upon receipt of such shares, Auteco will earn a 51% interest in PC Gold per the terms of the Earn-in Agreement. The parties will then execute a joint venture
shareholders’ agreement (the “JV Agreement”)  in  respect  of  PC  Gold.  Auteco  will  have  a  two-year  follow-on  period,  commencing  as  of  the  date  of  execution  of  the  JV
Agreement, within which to acquire an additional 19% interest in PC Gold per the Stage 2 Earn-In.

In  addition,  upon  completion  of  the  Stage  2  Earn-In,  Auteco  will  have  an  option  to  acquire  an  additional  10%  equity  interest  in  PC  Gold,  exercisable  any  time  following
completion of the Stage 2 Earn-In, by paying First Mining $3,000,000 in cash. First Mining’s residual 20% interest in the project is carried until a construction decision at
Pickle Crow, which is to be made after a final feasibility study and following Auteco having arranged sufficient financing to achieve commercial production. If Auteco should
fail to meet such requirements within the applicable time periods, the Earn-In Agreement will terminate and Auteco will be entitled to retain any interest which it has earned-
in to prior to the date of termination. Further details regarding the Earn-In are set out in the Company’s March 12, 2020 news release. In May 2020 and July 2020, Auteco
raised $5.1 million Australian dollars and $30.4 million Australian dollars, respectively, in equity placements from Australian and overseas investors.

On February 28, 2019, the Company received a letter from the Acting Director, Mine Rehabilitation, at the Ontario Ministry of Energy, Northern Development and Mines
(“MENDM”), which required the Company to submit a schedule for the development of a closure plan amendment for the Pickle Crow Gold Project. The Company complied
with  the  requirement  and  submitted  the  schedule  for  the  development  of  a  closure  plan  amendment  on  March  29,  2019.  The  submission  of  a  closure  plan  amendment
complete with cost estimates was initially due on November 1, 2019. The Company has been granted an extension and is working with the Ministry towards the filing of the
closure plan in Q2 2021. The Company has engaged consultants to assist with developing this plan. Pursuant to the Earn-In Agreement, Auteco is required to reimburse the
Company for a pro rata amount of its expenses with respect to any related bond requirements for the mine closure plan once it has completed the Stage 1 Earn-In, which will
result in Auteco owning 51% of the Pickle Crow Gold Project.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

Goldlund Gold Project, Ontario (owned by Treasury Metals as of August 7, 2020)

The Goldlund Gold Project is an advanced exploration stage project located in northwestern Ontario, approximately 60 km northeast of the town of Dryden. It consists of
1,349 mining claims (totaling 27,255 hectares), 27 patented claims (totaling 433 hectares), 1 mining lease (48.56 hectares), and 1 License of Occupation (74.84 hectares).
Goldlund Gold Project currently hosts 809,200 ounces of gold in the Indicated category and 876,954 ounces of gold in the Inferred category. Drilling in 2019 and early 2020
was  completed  on  the  project  to  better  define  both  the  extension  of  the  existing  resource  area  and  the  regional  scale  potential.  The  large  land  package  has  considerable
exploration potential, with the property extending over a strike-length of over 50 km with multiple exploration targets identified, including the Miller Prospect (“Miller”)
which was most recently drilled in late 2019. The project is in an area with excellent infrastructure and is accessible from a provincial highway.

A technical report titled “Technical Report Re-Issue, Goldlund Gold Project, Sioux Lookout, Ontario”, which has an effective date of July 22, 2020, was prepared by WSP for
Treasury Metals and was filed by Treasury Metals on SEDAR on August 7, 2020, and is available under their SEDAR profile at www.sedar.com.

Mining at the Goldlund Gold Project in the 1980s produced approximately 90,700 tonnes of ore grading 4.23 g/t Au from underground and 39,000 tonnes of ore grading 4.80
g/t from a small open pit. The project has year-round road access from Ontario Highway 72, which is 2 km to the south, and regional power lines are located 15 km to the
north.

During the year ended December 31, 2020 and prior to the Treasury Metals transaction, the most significant expenditures at the Goldlund Gold Project were $1,179,000 in
connection with First Mining’s 2020 drill campaign at the project of approximately 6,500 m in satisfaction of the Company’s remaining 2019 flow-through obligations.

Transaction with Treasury Metals Inc.

On August  7,  2020,  First  Mining  completed  its  transaction  with Treasury  Metals,  pursuant  to  which  Treasury  Metals  acquired  all  of  the  issued  and  outstanding  shares  of
Tamaka Gold Corporation (which, through a wholly-owned subsidiary, Goldlund Resources Inc., owned the Goldlund Gold Project) pursuant to the terms of a Share Purchase
Agreement. Under the terms of the transaction, First Mining received total consideration comprised of (i) 43.33 million common shares of Treasury Metals; (ii) 11.67 million
warrants of Treasury Metals with an exercise price of $1.50 for a 3-year term; (iii) a 1.5% NSR royalty on the Goldlund Gold Project (0.5% of which can be bought back by
Treasury Metals for $5 million in cash); and (iv) the right to certain contingent milestone payments totaling $5 million, payable in cash, on certain key advancements at the
Goldlund Gold Project.

Details of the contingent milestone payments are as follows:

●            $2.5 million payable upon receipt of a mining lease to extract material from an open pit mine at Goldlund; and
● 

$2.5 million payable upon 300,000 tonnes of ore that can form the basis of a mineral reserve being extracted from a mine at Goldlund.

The  Company  applied  equity  accounting  for  the  investment  in  the  Treasury  Metals  shares.  The  fair  value  of  the  Treasury  Metals  shares  at  closing  of  $78,000,000  was
determined  using  the  quoted  price  of  Treasury  Metals’  common  shares  on  August  7,  2020.  The  warrants  of  Treasury  Metals  have  been  accounted  for  as  FVTPL.  The
Company uses the Black-Scholes option pricing model to calculate the fair value of the warrants held in Treasury Metals both as at August 7, 2020 and on an ongoing basis.
The 1.5% NSR royalty on Goldlund was measured at a fair value of $3,709,000 and is included in “Others” in “Mineral Properties”.

Upon closing, First Mining held approximately 40% of the issued and outstanding common shares of Treasury Metals (on an undiluted basis) and had the right to appoint
three nominees to the board of directors of Treasury Metals. In August 2020, the Company exercised this right and nominated (and Treasury Metals subsequently appointed)
three individuals to the board of directors of Treasury Metals.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

In accordance with the terms of an Investor Rights Agreement signed in connection with the transaction, First Mining is required to distribute approximately 20.92 million
shares of Treasury Metals and all of the warrants of Treasury Metals to its shareholders within 12 months of closing of the transaction (the “Distribution”). Following the
Distribution,  First  Mining  will  retain  approximately  22.41  million  shares  of  Treasury  Metals,  leaving  the  Company  with  a  19.9%  ownership  interest.  As  at  December  31,
2020,  the  Company  has  recorded  a  liability  for  the  obligation  to  distribute  investments  of  $34,040,000.  As  the  distribution  will  be  a  transaction  with  shareholders,  the
obligation was recorded with a corresponding entry into shareholders equity.

For accounting purposes during the year ended December 31, 2020 the Company recorded an impairment of the Goldlund Gold Project amounting to $9,236,000 (2019 -
$nil), based on the fair value of the consideration received under the transaction with Treasury Metals. On August 7, 2020, as a result of closing the transaction with Treasury
Metals, the Company derecognized the Goldlund project mineral property costs with the exception of the retained NSR royalty interest, now recorded under “Other” mineral
properties. The Company also recorded equity income from the investment in Treasury Metals of $1,446,000 (2019 - $nil) during the year ended December 31, 2020, which
was predominantly relates to deferred income tax recoveries recorded by Treasury Metals in the fourth quarter of their 2020 financial statements. In addition, as at September
30, 2020, the Company recorded an impairment of the equity investment in Treasury Metals amounting to $15,634,000 (2019 - $nil), based on the recoverable amount of the
investment, which was indicated by the publicly quoted market price of Treasury Metals’ shares. It was determined that there was no additional impairment as at December
31, 2020.

Hope Brook Gold Project, Newfoundland

The Hope Brook Gold Project covers an area of 26,650 hectares in Newfoundland, including six mineral licenses, with a deposit hosted by pyritic silicified zones occurring
within a deformed, strike-extensive advanced argillic alteration zone. A technical report titled “2015 Mineral Resource Estimate Technical Report for the Hope Brook Gold
Project, Newfoundland and Labrador, Canada”, prepared by Mercator Geological Services Limited, was filed by the Company on SEDAR on November 27, 2015, and is
available under the Company’s SEDAR profile at www.sedar.com.

During the year ended December 31, 2020, the most significant expenditures at the Hope Brook Gold Project were:

● $122,000 for site employees’ salaries and management salary allocations;
● $91,000 for an aggregate study; and
● $20,000 for an advanced royalty payment.

The resource covers 1.5 km of an 8 km mineralized structure. Substantial infrastructure at the property includes a ramp to 350 metres (“m”) below surface with vent raise,
line-power to site, commercial barge and landing craft ramp, air strip, and a strong local labour force. The Hope Brook Gold Project was a former operating gold mine that
produced 752,163 oz Au from 1987 to 1997.

Sale of Mexican Exploration Projects

On April 28, 2020, the Company entered into a share purchase agreement with a third-party private company (the “Purchaser”) pursuant to which the Purchaser acquired all
of the issued and outstanding shares of 0924682 B.C. Ltd. and 1089568 B.C. Ltd., two wholly-owned subsidiaries of the Company that hold all of the shares of two Mexican
subsidiaries that owned all of the Company’s Mexican mineral properties. Consideration consisted of nominal cash, and the grant to the Company of a 2% NSR on 10 of the
11 mineral properties. The Purchaser has the right to buy-back 1% of each of these 10 NSRs by paying US$1 million to the Company for each NSR in respect of which the
buy-back right is exercised. From the date of this sale transaction, First Mining no longer holds any mineral properties in Mexico, and this sale will allow the Company to
focus its capital and resources on its Canadian mineral properties. The transaction resulted in a $303,000 loss on disposal of subsidiaries recorded on the statement of net loss
and comprehensive loss for the year ended December 31, 2020, and recycling of currency translation adjustment on disposal of Mexican subsidiaries amounting to $615,000.

NSRs owned by or available to First Mining

Through  recent  transactions,  the  Company  has  created  the  following  portfolio  of  seventeen  NSR  royalties  on  certain  of  our  mineral  properties  and  property  interests.  The
Company is currently evaluating all potential strategic opportunities available to enhance and optimize the value of its royalty portfolio.

(2)

MD&A titled “Non-IFRS Measures”.
“The certain non-cash items excluded” refers to the “Share-based payments expense”, “Impairment of non-current assets”, “Investments fair value loss”, “Loss on
disposal  of  subsidiaries”,  “Fair  value  loss  on  Silver  Stream  derivative  liability”,  “Deferred  income  tax  expense  (recovery)”  and  “Equity  loss  (income)  from
investment in Treasury Metals”.

(3) The basic and diluted loss per share calculations result in the same amount due to the anti‐dilutive effect of outstanding stock options and warrants in all periods.

Key trends in the quarterly results are as follows

Net loss - quarter to quarter fluctuations are typically due to the timing of non-cash items. Share-based payments expense, which fluctuates due to the timing and number of
stock option grants together with the associated fair value dollar amount calculated at the time of the grant, is one of the more common examples. Other non-cash items are
fair value movements on the silver stream derivative liability and certain investments based on underlying market prices at period end. As can be seen in the table above, the
fluctuation in net loss after excluding these non-cash items does not tend to vary nearly as much.

Cash and cash equivalent – fluctuations are principally due to the amount and timing of cash used to fund investing activities at the Company’s mineral property portfolio,
offset by the success of financings provided by private placements, public offerings, and the exercise of options and warrants to support such activities.

Total assets – quarterly changes are the direct result of fluctuations described above in cash and cash equivalent and investments in the current asset category, and due to
mineral property expenditure additions and more recently the investment in Treasury Metals in the non-current asset category.

Non-current liabilities – changes occur predominantly due to the Silver Stream derivative liability fair value movement at each period end date.

Increase  is  primarily  due  to  higher  employee  salaries  and  bonus  accrual  allocations.  In  addition,
professional fees were higher because of the increase in 2020 transactional activity.
Decrease  is  due  to  lower  employee  salaries  and  consulting  fee  allocations  to  exploration  and
evaluation activities vs 2019.

(1)   Working capital is a non-IFRS measurement with no standardized meaning under IFRS and may not be comparable to similar financial measures presented by other

issuers. For further information and a detailed reconciliation, please see the section “Non-IFRS Measures – Working Capital”.

Key reasons for variances from December 31, 2019 to December 31, 2020:

● The  increase  of  $22,999,000  in  cash  and  cash  equivalents  was  primarily  due  to  cash  raised  from  the  bought  deal  financing,  private  placements,  at‐the‐market
("ATM") sales and proceeds from sale of First Majestic shares received per the terms of the Silver Stream agreement, offset by cash used in operating and investing
activities;

● Cash used in operating activities is comparable between fiscal 2019 and fiscal 2020;
● Cash used in investing activities increased due to higher development activities on the Springpole Gold Project which included drilling expenditures partially offset

by proceeds from sale of investments;

● Cash provided by financing activities increased due to cash raised from the bought deal financing, private placements, ATM sales, and cash proceeds received from

First Majestic per terms of the Silver Stream agreement;

● Working capital increased due to increase in cash and cash equivalents as discussed above and increase in the market value of investments, offset by Option – PC

Gold and Obligation to distribute investments.

Trends in Liquidity, Working Capital, and Capital Resources

As at December 31, 2020, the Company has working capital of $9,201,000 (December 31, 2019 - $5,780,000). The Company has no history of revenues from its operating
activities. The Company is not in commercial production on any of its mineral properties and accordingly does not generate cash from operations. During the year ended
December  31,  2020,  the  Company  had  negative  cash  flow  from  operating  activities.  The  Company  anticipates  it  will  have  negative  cash  flow  from  operating  activities  in
future periods.

The Company has, in the past and during the year ended December 31, 2020, financed its activities by raising capital through issuances of new shares, other means such as
silver stream upfront proceeds and/or sales of its investments in other companies. In addition to adjusting spending, disposing of assets and seeking other non-equity sources
of  financing,  the  Company  will  remain  reliant  on  equity  markets  for  raising  capital  until  it  can  generate  positive  cash  flow  from  operations  to  finance  its  exploration  and
development programs.

The Company believes it has sufficient cash resources to maintain its mineral properties in good standing for the next twelve months.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

OUTLOOK

We remain focused on advancing the Company’s strategic objectives and near-term milestones, which include the following:

● Advancing the Springpole Environmental Assessment process which includes a focus on community, indigenous rights holder and stakeholder consultations.
● Springpole technical studies, including metallurgical work, geotechnical optimization and further process optimization following the release and publication of the

PFS.

● Springpole exploration drilling (33 holes, 6,000 m) - to identify and follow-up on regional targets.
● Cameron drill program (10 holes, 2,000 m) – to extend local understanding and identify new targets.
● Evaluating its Québec mineral properties and potential for partnership opportunities.
● Maintaining strong balance sheet and cash position to fund investing activities consistent with First Mining’s business strategy.
● Providing support as needed to partnership projects (Pickle Crow, Goldlund-Goliath) which will continue to enable the Company to surface value from these direct

and indirect interests.

● Establishing and initiating environmental, social and governance (“ESG”) reporting framework in 2021, including a new Board ESG Committee.

FINANCIAL INSTRUMENTS

All financial instruments are required to be measured at fair value on initial recognition. Fair value is based on quoted market prices unless the financial instruments are not
traded in an active market. In this case, the fair value is determined by using valuation techniques like the Black-Scholes option pricing model or other valuation techniques.
Measurement  in  subsequent  periods  depends  on  the  classification  of  the  financial  instrument.  A  description  of  financial  instruments  and  their  fair  value  is  included  in  the
audited consolidated financial statements for the year ended December 31, 2020, filed on SEDAR at www.sedar.com.

In the normal course of business, the Company is inherently exposed to certain financial risks, including market risk, credit risk and liquidity risk, through the use of financial
instruments. The timeframe and the manner in which we manage these risks varies based upon our assessment of these risks and available alternatives for mitigation. We do
not acquire or issue derivative financial instruments for trading or speculative purposes. All transactions undertaken are to support our operations.

RELATED PARTY TRANSACTIONS 

Amounts paid to related parties were incurred in the normal course of business and measured at the exchange amount, which is the amount agreed upon by the transacting
parties and on terms and conditions similar to non-related parties. There were no significant transactions with related parties outside of the ordinary course of business during
the year ended December 31, 2020.

OFF-BALANCE SHEET ARRANGEMENTS

The Company has no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on the results of operations or financial condition of
the Company including, without limitation, such considerations as liquidity and capital resources.

Alternative performance measures in this document such as “cash cost”, “AISC” and “AIC” are furnished to provide additional information. These non-IFRS performance
measures are included in this MD&A because these statistics are used as key performance measures that management uses to monitor and assess future performance of the
Springpole Gold Project, and to plan and assess the overall effectiveness and efficiency of mining operations.

Certain Non-IFRS financial measures used in this MD&A and common to the gold mining industry are defined below.

Total Cash Costs and Total Cash Costs per Gold Ounce - Total Cash Costs are reflective of the cost of production. Total Cash Costs reported in the PFS include mining costs,
processing,  water  &  waste  management  costs,  on-site  general  &  administrative  costs,  treatment  &  refining  costs,  royalties  and  silver  stream  credits.  Total  Cash  Costs  per
Ounce is calculated as Total Cash Costs divided by total LOM payable gold ounces.

All-in Sustaining Costs (“AISC”) and AISC per Gold Ounce - AISC is reflective of all of the expenditures that are required to produce an ounce of gold from operations.
AISC reported in the PFS includes Total Cash Costs, sustaining capital and closure costs. AISC per Ounce is calculated as AISC divided by total LOM payable gold ounces.

In addition, the Company has included non-IFRS measures in the annual and quarterly info tables above, which include working capital (calculated as Current Assets less
Current  Liabilities)  and  Net  Loss  excluding  certain  non-cash  items  (calculated  as  Net  Loss  excluding  share  based  payments  expense,  impairment  of  non-current  assets,
investments fair value loss, loss on disposal of subsidiaries, fair value loss on silver stream derivative liability, deferred income tax expense (recovery) and equity income
from investment in Treasury Metals) which should be read in conjunction with its financial statements which are prepared in accordance with IFRS. The Company believes
that  these  measures  provide  investors  with  an  improved  ability  to  evaluate  the  performance  of  the  Company.  Non-IFRS  measures  do  not  have  any  standardized  meaning
prescribed  under  IFRS.  Therefore,  such  measures  may  not  be  comparable  to  similar  measures  employed  by  other  companies.  The  data  is  intended  to  provide  additional
information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

ACCOUNTING POLICIES

The Company’s significant accounting policies are in accordance with IFRS and are contained in the audited consolidated financial statements for the year ended December
31, 2020. Furthermore, there were no changes in the Company’s accounting policies during the 2020 financial year.

CRITICAL ACCOUNTING ESTIMATES

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  IFRS  requires  management  to  make  judgments,  estimates  and  assumptions  which  affect  the
reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period. Estimates are based on historical experience and other factors considered to be reasonable and are reviewed on an ongoing
basis. Revisions to estimates and the resulting effects on the carrying amounts of the Company’s assets and liabilities are accounted for prospectively.
 Estimation uncertainties are described in the Company’s audited consolidated financial statements for the year ended December 31, 2020.

CRITICAL ACCOUNTING JUDGMENTS

The preparation of financial statements requires management to exercise judgment in the process of applying its accounting policies. Judgments are regularly evaluated and
are based on management’s experience and other factors, including expectations about future events that are believed to be reasonable under the circumstances. The following
section discusses significant accounting policy judgments which have been taken in the financial statements for the year ended December 31, 2020:

Mineral Property Impairment Indicators

In accordance with the Company’s accounting policy for its mineral properties, exploration and evaluation expenditures on mineral properties are capitalized. There is no
certainty that the expenditures made by the Company in the exploration of its property interests will result in discoveries of commercial quantities of minerals. The Company
applies judgment to determine whether indicators of impairment exist for these capitalized costs.

Management uses several criteria in making this assessment, including the period for which the Company has the right to explore, expected renewals of exploration rights,
whether  substantive  expenditures  on  further  exploration  and  evaluation  of  mineral  properties  are  budgeted,  and  evaluation  of  the  results  of  exploration  and  evaluation
activities up to the reporting date.

Impairment of Investment in Associate

With respect to its investment in associate, the Company is required to make estimates and judgments about future events and circumstances and whether the carrying amount
of the asset exceeds its recoverable amount. Recoverability depends on various factors, including the identification of economic recoverability of reserves at Treasury Metals’
exploration properties, the ability of Treasury Metals to obtain the necessary financing to complete the development, and future profitable production or proceeds from the
disposition of the Treasury Metals shares themselves. The publicly quoted share price of Treasury Metals is also a source of objective evidence about the recoverable amount
of the equity investment.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

Milestone Payments per Share Purchase Agreement with Treasury Metals

The Company applied judgment in the determination of whether to recognize the contingent milestone payments in accordance with the Treasury Share Purchase Agreement
(defined  in  Note  4  to  the  audited  consolidated  financial  statements  for  the  years  ended  December  31,  2020  and  December  31,  2019).  In  management’s  judgment,  there  is
uncertainty of these milestones being reached. Management considered the expected length of time that may pass before this uncertainty is resolved, as well as the fact that
achievement of the milestones is outside of the Company’s control. Therefore, the milestone payments have not been recognized as assets as at December 31, 2020.

ACCOUNTING STANDARDS ISSUED BUT NOT YET APPLIED

There are no IFRS or International Financial Reporting Interpretations Committee interpretations that are not yet effective that would be expected to have a material impact
on the Company’s consolidated financial statements.

RISKS AND UNCERTAINTIES

The Company is subject to a number of risks and uncertainties, each of which could have an adverse effect on its business operations or financial results. Some of these risks
and uncertainties are detailed below. For a comprehensive list of the Company’s risks and uncertainties, see the Company’s AIF for the year ended December 31, 2020 under
the heading “Risks that can affect our business”, which is available under our SEDAR profile at www.sedar.com, and on EDGAR as an exhibit to Form 40-F.

Risks related to Financial Instruments

The  Company  thoroughly  examines  the  various  financial  instruments  and  risks  to  which  it  is  exposed  and  assesses  the  impact  and  likelihood  of  those  risks.  These  risks
include market risk (including equity price risk, foreign currency risk, interest rate risk and commodity price risk), credit risk, liquidity risk, and capital risk. Where material,
these risks are reviewed and monitored by the Board.

The Board has overall responsibility for the determination of the Company’s risk management objectives and policies. The overall objective of the Board is to set policies that
seek to reduce risk as much as possible without unduly affecting the Company’s competitiveness and flexibility.

a) Market Risk

Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate due to changes in market prices. Market risk includes equity price risk,
foreign currency risk, interest rate risk and commodity price risk.

Equity Price Risk

The Company is exposed to equity price risk as a result of holding investments in equity securities, which are comprised of investments and mineral property investments, in
other mineral property exploration companies.

If the fair value of our investments in equity instruments designated as FVTPL had been 10% higher or lower as at December 31, 2020, net loss for the year ended December
31, 2020 would have decreased or increased, respectively, by approximately $1,504,000 (2019 – $nil), as a result of changes in the fair value of equity investments. If the fair
value of our investments in equity instruments designated as FVTOCI had been 10% higher or lower as at December 31, 2020, other comprehensive income (loss) for the year
ended December 31, 2020 would have decreased or increased, respectively, by approximately $1,011,000 (2019 – $717,000), as a result of changes in the fair value of equity
investments.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

Foreign Currency Risk

The Company is exposed to financial risk related to the fluctuation of foreign exchange rates. As at December 31, 2020, the Company was exposed to currency risk on the
following financial instruments denominated in US$. The sensitivity of the Company’s net loss due to changes in the exchange rate between the US$ against the Canadian
dollar is included in the table below in Canadian dollar equivalents:

Cash and cash equivalents

Interest Rate Risk

  $
  $
  $
  $

5,567 
(13,260)
(7,693)
(769)

Interest rate risk is the risk that future cash flows will fluctuate as a result of changes in market interest rates. The Company does not have any borrowings that are subject to
fluctuations in market interest rates. Interest rate risk is limited to potential decreases on the interest rate offered on cash and cash equivalents held with chartered Canadian
financial  institutions.  The  Company  manages  its  interest  rate  risk  by  maximizing  the  interest  income  earned  on  excess  funds  while  maintaining  the  necessary  liquidity  to
conduct its day-to-day operations. The Company considers this risk to be immaterial.

Commodity price risk

The  Company  is  subject  to  commodity  price  risk  from  fluctuations  in  the  market  prices  for  gold  and  silver.  Commodity  price  risks  are  affected  by  many  factors  that  are
outside the Company’s control including global or regional consumption patterns, the supply of and demand for metals, speculative activities, the availability and costs of
metal substitutes, inflation, and political and economic conditions. The financial instrument impacted by commodity prices is the Silver Stream derivative liability.

b) Credit Risk

Credit risk is the risk of financial loss to the Company if a counterparty to a financial instrument fails to meet its contractual obligations. Financial instruments which are
potentially subject to credit risk for the Company consist primarily of cash and cash equivalents, accounts and other receivables, and the reclamation deposit. The Company
considers credit risk with respect to its cash and cash equivalents to be immaterial as cash and cash equivalents are mainly held through high credit quality major Canadian
financial institutions as determined by ratings agencies. As a result, the Company does not anticipate any credit losses.

c) Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company’s policy is to ensure that it will have sufficient
cash  to  allow  it  to  meet  its  liabilities  when  they  become  due,  under  both  normal  and  stressed  conditions,  without  incurring  unacceptable  losses  or  risking  damage  to  the
Company’s  reputation.  The  Company  manages  its  liquidity  risk  by  preparing  annual  estimates  of  exploration  and  administrative  expenditures  and  monitoring  actual
expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.
See the section of this MD&A titled “Financial Liabilities and Commitments” for a summary of the maturities of the Company’s financial liabilities as at December 31, 2020
based on the undiscounted contractual cash flows.

As at December 31, 2020, the Company had cash and cash equivalents of $28,901,000 (December 31, 2019 – $5,902,000).

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

d) Capital Risk Management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to pursue the exploration and retention of its
mineral properties. The Company has historically demonstrated the ability to raise new capital through equity issuances and/or through surplus cash as part of its acquisitions.
In  the  management  of  capital,  the  Company  includes  the  components  of  shareholders’  equity  as  well  as  cash.  The  Company  prepares  annual  estimates  of  exploration  and
administrative expenditures and monitors actual expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.

Other Risk Factors

Financing Risks

The Company has finite financial resources, has no current source of operating cash flow and has no assurance that additional funding will be available to it for its future
activities, including exploration or development of mineral projects. Such further activities may be dependent upon the Company’s ability to obtain financing through equity
or debt financing or other means.  Failure to obtain additional financing could result in delay or indefinite postponement of exploration and development of the Company’s
existing mineral projects and could result in the loss of one or more of its properties.
Exploration and Development Risks

The exploration for and development of minerals involves significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate.
These risks include:

● few properties that are explored are ultimately developed into producing mines;
● there can be no guarantee that the estimates of quantities and qualities of minerals disclosed will be economically recoverable;
● with all mining operations there is uncertainty and, therefore, risk associated with operating parameters and costs resulting from the scaling up of extraction methods

tested in pilot conditions; and

● mineral exploration is speculative in nature and there can be no assurance that any minerals discovered will result in an increase in our resource base.

Exploration and development of mineral properties is capital intensive and unsuccessful exploration or development programs could have a material adverse impact on the
Company’s operations and financial condition.

Global Financial Conditions

Global  financial  conditions  have,  at  various  times  in  the  past  and  may,  in  the  future,  experience  extreme  volatility.  Many  industries,  including  the  mining  industry,  are
impacted by volatile market conditions. Global financial conditions may be subject to sudden and rapid destabilizations in response to economic shocks or other events, such
as developments concerning COVID-19. A slowdown in the financial markets or other economic conditions, including but not limited to consumer spending, employment
rates, business conditions, inflation, fluctuations in fuel and energy costs, consumer debt levels, lack of available credit, the state of the financial markets, interest rates and tax
rates, may adversely affect the Company’s growth and financial condition. Future economic shocks may be precipitated by a number of causes, including government debt
levels, fluctuations in the price of oil and other commodities, volatility of metal prices, geopolitical instability, changes in laws or governments, war, terrorism, the volatility
of currency exchanges inflation or deflation, the devaluation and volatility of global stock markets, pandemics and natural disasters. Any sudden or rapid destabilization of
global economic conditions could impact the Company’s ability to obtain equity or debt financing in the future on terms favourable to the Company or at all. In such an event,
the Company’s operations and financial condition could be adversely impacted.

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

Public Health Crises

The Company's business, operations and financial condition could be materially adversely affected by the outbreak of epidemics, pandemics or other health crises, such as
COVID-19, and by reactions by government and private actors to such outbreaks. As at the date of this MD&A, the global reactions to the spread of COVID-19 have led to,
among other things, significant restrictions on travel, quarantines, temporary business closures and a general reduction in consumer activity. While these effects are expected
to be temporary, the duration of the disruptions to business internationally and the related financial impact cannot be estimated with any degree of certainty at this time. Such
public health crises can result in disruptions and extreme volatility in financial markets and global supply chains as well as declining trade and market sentiment and reduced
mobility of people, all of which could impact commodity prices, interest rates, credit ratings, credit risk, availability of financing and inflation. The risks to the Company of
such  public  health  crises  also  include  risks  to  employee  health  and  safety  and  may  result  in  a  slowdown  or  temporary  suspension  of  operations  at  some  or  all  of  the
Company's mineral properties as well as its head office. Although the Company has the capacity to continue certain administrative functions remotely, many other functions,
including the conduct of exploration and development programs, cannot be conducted remotely and may be impacted or delayed if the Company experiences limitations on
employee mobility. At this point, the extent to which COVID-19 may impact the Company remains uncertain; however, it is possible that COVID-19 could have a material
adverse  effect  on  the  Company's  business,  results  of  operations  and  financial  condition.  There  can  be  no  assurances  that  the  Company  will  not  be  required  to  further
demobilize its personnel and contractors at any of its mineral projects in due to the ongoing COVID-19 pandemic. Any such demobilization may have an adverse impact on
the Company’s ability to conduct exploration and further advance its work programs on the affected properties.

Risks Generally

 Management’s Discussion & Analysis
 For the three months and year ended December 31, 2020

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s Management, with the participation of its CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting as
such term is defined in the SEC’s rules and the rules of the Canadian Securities Administrators. The Company’s internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of financial reporting and the preparation of annual financial statements for external purposes in accordance with
IFRS as issued by the IASB. The Company’s internal control over financial reporting includes policies and procedures that:

● address maintaining records that accurately and fairly reflect, in reasonable detail, the transactions and dispositions of assets of the Company;
● provide reasonable assurance that transactions are recorded as necessary for preparation of financial statements in accordance with IFRS;
● provide  reasonable  assurance  that  the  Company’s  receipts  and  expenditures  are  made  only  in  accordance  with  authorizations  of  Management  and  the  Company’s

Directors; and

● provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition  of  the  Company’s  assets  that  could  have  a

material effect on the Company’s consolidated financial statements.

The  Company’s  internal  control  over  financial  reporting  may  not  prevent  or  detect  all  misstatements  because  of  inherent  limitations.  Additionally,  projections  of  any
evaluation of effectiveness for future periods are subject to the risk that controls may become inadequate because of changes in conditions or deterioration in the degree of
compliance with the Company’s policies and procedures.

In the first quarter of 2020, the Company’s employees began to work remotely. Since then, the Company has reopened its offices and its employees have performed their
duties  through  a  combination  of  working  remotely  and  in  the  office.  This  change  has  required  certain  processes  and  controls  that  were  previously  done  or  documented
manually to be completed and retained in electronic form. Despite the changes required by the current environment, there have been no significant changes in our internal
controls during the year ended December 31, 2020 that have materially affected, or are likely to materially affect, the Company’s internal control over financial reporting.

LIMITATIONS OF CONTROLS AND PROCEDURES

The Company’s Management, including the CEO and CFO, believes that any disclosure controls and procedures or internal control over financial reporting, no matter how
well conceived and operated, may not prevent or detect all misstatements because of inherent limitations. Further, the design of a control system must reflect the fact that
there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot
provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the
realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by
the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control. The design of any control system is also based in part
upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential
future conditions. Accordingly, because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

mineral reserve and mineral resource estimates; statements regarding regulatory approval and permitting including, but not limited to, EA approval for the Springpole Gold
Project  and  the  expected  timing  of  such  EA  approval;  statements  regarding  the  Company’s  anticipated  timing  to  receive  final  approval  from  the  MECP  of  the  Terms  of
Reference for the Springpole Gold Project, and consultations in respect thereof; statements regarding the Company's compliance with laws and regulations including, but not
limited  to  environmental  laws  and  regulations;  statements  regarding  the  Pickle  Crow  Gold  Project  Earn-In  Agreement  and  payouts,  share  issuances  and  exploration

controls over financial reporting; and statements regarding the preparation or conduct of studies and reports and the expected timing of the commencement and completion of
such studies and reports.

There can be no assurance that such statements will prove to be accurate, and future events and actual results could differ materially from those anticipated in such statements.
Important factors that could cause actual results to differ materially from the Company’s expectations are disclosed under the heading “Risks that can affect our business” in
the  Company’s  AIF  for  the  year  ended  December  31,  2020  and  other  continuous  disclosure  documents  filed  from  time  to  time  via  SEDAR  with  the  applicable  Canadian
securities regulators. Forward-looking statements are based on the estimates and opinions of management on the date the statements are made, and the Company does not
undertake any obligation to update forward-looking statements should conditions or our estimates or opinions change, except as required by applicable laws. Actual results
may  differ  materially  from  those  expressed  or  implied  by  such  forward-looking  statements.  These  statements  involve  known  and  unknown  risks,  uncertainties,  and  other
factors  that  may  cause  the  Company’s  actual  results,  levels  of  activity,  performance  or  achievements  to  be  materially  different  from  any  future  results,  levels  of  activity,
performance or achievement expressed or implied by these forward-looking statements.

The Company believes that the expectations reflected in any such forward-looking statements are reasonable, but no assurance can be given that these expectations will prove
to be correct and such forward-looking statements included herein this MD&A should not be unduly relied upon.

CAUTIONARY NOTE TO U.S. INVESTORS REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

This MD&A has been prepared in accordance with the requirements of Canadian securities laws, which differ in certain material respects from the disclosure requirements of
United States securities laws. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance
with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) 2014 Definition Standards on Mineral Resources and Mineral Reserves, adopted by
the CIM Council, as may be amended from time to time. These definitions differ from the definitions in the United States Securities and Exchange Commission (the “SEC”)
rules  applicable  to  domestic  United  States  companies.  In  addition,  the  terms  “mineral  resource”,  “measured  mineral  resource”,  “indicated  mineral  resource”  and
“inferred mineral resource” are defined under the 2014 CIM definition standards, and are required to be disclosed by NI 43-101. However, these terms are not defined under
the SEC rules applicable to domestic United States companies. Accordingly, information concerning mineral deposits set forth or incorporated by reference in this MD&A
may not be comparable with information made public by companies that report in accordance with U.S. standards.
