Compliance with NI 43-101 

As required by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), Capstone 
has filed technical reports detailing the technical information related to its material mineral properties discussed 
herein. For the purposes of NI 43-101, Capstone’s material mineral properties as of December 31, 2019 are the 
Pinto  Valley  Mine  and  the  Cozamin  Mine.  Unless  otherwise  indicated,  Capstone  has  prepared  the  technical 
information  in  this  Annual  Information  Form  (“Technical  Information”)  based  on  information  contained  in  the 
technical  reports,  news  releases  and  other  public  filings  (collectively,  the  “Disclosure  Documents”)  available 
under Capstone’s profile on SEDAR at www.sedar.com. Each Disclosure Document was prepared by, or under 
the supervision of, or approved by a Qualified Person as defined in NI 43-101. For readers to fully understand the 
information in this Annual Information Form, they should read the Disclosure Documents in their entirety, including 
all  qualifications,  assumptions  and  exclusions  that  relate  to  the  Technical  Information  set  out  in  this  Annual 
Information Form which qualifies the Technical Information. The Disclosure Documents are each intended to be 
read as a whole, and sections should not be read or relied upon out of context. Readers are advised that Mineral 
Resources that are not Mineral Reserves do not have demonstrated economic viability. The Technical Information 
is subject to the assumptions and qualifications contained in the Disclosure Documents. 

Classification of Mineral Reserves and Mineral Resources 

In this Annual Information  Form and  as required by  NI 43-101, the definitions  of Proven  and  Probable Mineral 
Reserves  and  Measured,  Indicated  and  Inferred  Mineral  Resources  are  those  used  by  Canadian  provincial 
securities  regulatory  authorities  and  conform  to  the  definitions  utilized  by  the  Canadian  Institute  of  Mining, 
Metallurgy and Petroleum (“CIM”) in the “CIM Definition Standards for Mineral Resources and Mineral Reserves” 
adopted on August 20, 2000, as amended (“CIM Standards”). The CIM Standards were updated in in 2010 and 
2014 at the request of the CIM Standing Committee on Mineral Reserve and Mineral Resource Definitions. Our 
Pinto Valley, Cozamin and Santo Domingo NI 43-101 Technical Reports were written in accordance with the CIM 
Standards updated in 2014.  

Cautionary Note to US Investors Concerning Estimates of Mineral Reserves and Mineral Resources 

The disclosure in this Annual Information Form uses Mineral Resource and Mineral Reserve classification terms 
that comply with reporting standards in Canada, and, unless otherwise indicated, all Mineral Resource and Mineral 
Reserve estimates included in this Annual Information Form have been prepared in accordance with NI 43-101. 
NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public 
disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards 
differ significantly from the current disclosure requirements of the SEC set forth in Industry Guide 7. Consequently, 
Mineral Resource and Mineral Reserve information contained in this Annual Information Form is not comparable 
to similar information that would generally be disclosed by US companies in accordance with the rules of the SEC. 

In  particular,  the  SEC’s  Industry  Guide  7  applies  different  standards  in  order  to  classify  mineralization  as  a 
Reserve. As a result, the definitions of Proven and Probable Reserves used in NI 43-101 differ from the definitions 
in  Industry  Guide  7.  Under  SEC  standards,  mineralization  cannot  be  classified  as  a  “Reserve”  unless  the 
determination has been made that the mineralization could be economically and legally produced or extracted at 
the  time  the  Reserve  determination  is  made.  Accordingly,  Mineral  Reserve  estimates  contained  in  this  Annual 
Information Form may not qualify as “Reserves” under SEC standards. 

In  addition,  this  Annual  Information  Form  uses  the  terms  “Measured  Mineral  Resources”,  “Indicated  Mineral 
Resources”  and  “Inferred  Mineral  Resources”  to  comply  with  the  reporting  standards  in  Canada.  The  SEC’s 
Industry Guide 7 does not recognize Mineral Resources and US companies are generally not permitted to disclose 
Mineral Resources in documents they file with the SEC. Investors are cautioned not to assume that any part or all 
of the mineral deposits in these categories will ever be converted into SEC defined mineral “Reserves.” Further, 
“inferred Mineral Resources” have a great amount of uncertainty as to their existence and as to whether they can 
be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of an 
inferred Mineral Resource exists. In accordance with Canadian rules, estimates of “inferred Mineral Resources” 

5 

 
 
cannot  form  the  basis  of  feasibility  or  other  economic  studies,  except  in  rare  cases.  In  addition,  disclosure  of 
“contained  ounces”  in  a  Mineral  Resource  estimate  is  permitted  disclosure  under  NI  43-101  provided  that  the 
grade or quality and the quantity of each category is stated; however, the SEC normally only permits issuers to 
report mineralization that does not constitute “Reserves” by SEC standards as in place tonnage and grade without 
reference  to  unit  measures.  For  the  above  reasons,  information  contained  in  this  Annual  Information  Form 
containing  descriptions  of  our  Mineral  Resource  and  Mineral  Reserve  estimates  is  not  comparable  to  similar 
information made public by US companies subject to the reporting and disclosure requirements of the SEC.

(unless indicated otherwise in this Annual Information Form). 
Co: cobalt 
Cu: copper 
CuEq: copper equivalent value, calculated by dividing the sum of the secondary metals multiplied by their own 
commodity prices by the copper metal price  
diamond drillholes: holes drilled by a method whereby rock is drilled with a diamond impregnated, hollow drilling 
bit which produces a continuous, in situ record of the rock mass intersected in the form of solid cylinders of rock 
which are referred to as core.

tailings storage facility is safe, in that it is designed and constructed in accordance with the current state of practice 
and applicable regulations, statutes, guidelines, codes, and standards. 
Fault: a fracture in a rock across which there has been displacement 
Fe: iron 
G or g: gram 
Grade: the amount of valuable mineral in each tonne of ore, expressed as ounces per ton or grams per tonne for 
precious metal and as a percentage by weight for other metals.   
g/t: grams per metric tonne. 
g/t: grams per metric tonne. 
Ha: hectares 
host rock: a volume of rock within which mineralization or an ore body occurs. 
HQ: approximately 63 millimetre diameter diamond drill core 
Hydrothermal: applied to metamorphic and magmatic emanations high in water content; the processes in which 
they are concerned; and the rocks or ore deposits, alteration products, and springs produces by them.

Indicated Mineral Resource: in accordance with CIM Definition Standards, is that part of a Mineral Resource for 
which  quantity,  grade  or  quality,  densities,  shape  and  physical  characteristics  are  estimated  with  sufficient 
confidence  to  allow  the  application  of  Modifying  Factors  (as  defined  below)  in  sufficient  detail  to  support  mine 
planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately 
detailed and reliable exploration, sampling and testing and is sufficient to 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. 
Inferred Mineral Resources: in accordance with CIM Definition Standards, that part of a Mineral Resource for 
which  quantity  and  grade  or  quality  are  estimated  on  the  basis  of  limited  geological  evidence  and  sampling. 
Geological  evidence  is  sufficient  to  imply  but  not  verify  geological  and  grade  or  quality  continuity.  An  Inferred 
Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must 
not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources 
could be upgraded to Indicated Mineral Resources with continued exploration.

Masl: metres above sea level. 
Measured Mineral Resource: in accordance with CIM Definition Standards, is that part of a Mineral Resource for 
which  quantity,  grade  or  quality,  densities,  shape,  and  physical  characteristics  are  estimated  with  confidence 
sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the 
economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling 
and testing and is sufficient 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: in accordance with CIM Definition Standards, economically mineable part of a Measured and/or 
Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the 
material is mined or  extracted and  is defined by studies at pre-feasibility or feasibility level  as appropriate that 
include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could 
reasonably be justified. The reference point at which Mineral Reserves are defined, usually the point where the 
ore is delivered to the processing plant, must be stated. It is important that, in all situations where the reference 
point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully 
informed as to what is being reported. The public disclosure of a Mineral Reserve must be demonstrated by a pre-
feasibility study or feasibility study. 
Mineral Resource: in accordance with CIM Definition Standards, is a concentration or occurrence of solid material 
of economic interest 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. Mineral Resources are sub-divided, in order of increasing geological confidence, 
into Inferred, Indicated and Measured categories.

In June, Capstone announced the results of an updated Mineral Resource estimate for Cozamin in Mexico, 
and  subsequently  in  December,  an  updated  technical  report  resulted  in  an  increase  of  Proven  and 
Probable Mineral Reserves by 89% over the Mineral Reserves as at December 31, 2017, to 6.2 million 
tonnes grading 1.60% copper. Inferred Mineral Resources were also re-estimated to include high grade 
results from step-out drilling to October 24, 2018  and resulted in an increase to 17 million tonnes at  a 
copper grade of 1.11%; including 9.5 million tonnes at a copper grade of 1.61% in the Mala Noche Footwall 
Zone ("MNFWZ").  

•  On  November  26,  released  an  updated  technical  report  for  Santo  Domingo  and  launched  a  strategic 

process to right size or monetize Capstone’s 70% ownership.  

•  At Santo Domingo, three of the five long-lead permits required for construction were received.  
•  The  union  member  employees  at  Pinto  Valley  voted  to  ratify  a  new  four-year  collective  bargaining 

agreement, which was effective May 30.  

•  On October 11, Capstone announced it was putting Minto on care and maintenance to preserve its value, 
while continuing to explore value maximizing alternatives. All operations ceased in the fourth quarter once 
the ore stockpile was processed. Minto retained a core team of employees to oversee the site and meet 
environmental monitoring and legal obligations during the care and maintenance phase.  

2017 

•  On December 31, the copper price protection program set up in 2016 to assure continued debt repayment 

through 2017 was completed, resulting in full exposure to copper prices starting January 1, 2018.

3 – DESCRIPTION OF THE BUSINESS 

3.1 

General 

Capstone  is  a  Canadian  base  metals  mining  company,  focused  on  copper  in  politically  safe,  mining  friendly 
jurisdictions in the Americas. We have grown through a combination of exploration, development and acquisition 
of mineral properties and currently operate two producing copper mines: Pinto Valley in the US and Cozamin in 
Mexico.  

Our principal product is copper, with zinc, lead, molybdenum, silver and gold produced and sold as by-products. 
We  are  focused  on  optimizing  our  operations  and  assets  to  organically  grow  our  production  profile  and  are 
committed to the responsible development of our assets and the environments in which we operate. Capstone’s 
material mineral properties consist of: 

•  Pinto Valley Mine, an open-pit, copper mine located in Arizona, US; and 
•  Cozamin Mine, an underground, copper-silver mine located in the State of Zacatecas, Mexico. 

Capstone also owns 70% of the large-scale copper-iron Santo Domingo development project in Chile. In addition 
to ongoing exploration at the Cozamin Mine aimed at increasing mine life and throughput, we have a portfolio of 
early-stage, base metals exploration projects and are actively pursuing additional exploration opportunities through 
staking and acquiring properties and earn-in and/or joint venture models.

2  Pinto Valley gold production reaches payable levels from time to time. Any payable gold production will be reported in the 
period revenue is received. Gold and silver are not assayed on site, resulting in a significant lag time in receiving data. As such, 
this figure is an estimate. 
*  Silver  and  gold  have  not  been  estimated  in  the  Pinto  Valley  resource  model.  Only  recovered  silver  and  payable  gold  is 
reported for this mine. 
** Gold has not been estimated in the Cozamin resource model. Only payable gold is reported. 

During the year ended December 31, 2019, we generated gross revenue of $461.8 million primarily from the sale 
of 152.4 million pounds of payable copper. The year ended December 31,2018 generated gross revenue of $451.3 
million primarily from the sale of 143.5 million pounds of payable copper.

Pinto Valley production is primarily copper concentrate with a small amount of copper cathode produced from run-
of-mine leaching and SX/EW production and molybdenum concentrate as a by-product. The Mine also recovers 
a small amount of silver and gold as a by-product, though it is not estimated in the block model and is not included 
in the Mineral Resource or Mineral Reserve estimate. In 2019, 100% of the copper concentrate production was 
exported to Asia, specifically Japan and Korea as well as the Philippines since the implementation of the tariffs on 
US-origin material in mid-2018. In 2019, 100% of the copper concentrate was hauled using a modular truck system 
and  shipped  out  of  the  port  of  Guaymas,  Mexico.  The  copper  cathode  and  molybdenum  concentrate  are  sold 
through a competitive tendering process.  

Cozamin concentrate production is primarily copper with lesser amounts of by-product zinc and lead concentrate 
and significant  by-product  silver. The copper concentrate is  delivered by  truck under an  agreement to a major 
trading company in Manzanillo, Mexico. Depending on market conditions the copper concentrate is sold under an 
annual or multi-year agreement. Similarly, the zinc and lead concentrates are sold under annual tenders or multi-
year agreements and delivered by truck to Manzanillo or local Mexican smelters.  

Competitive Conditions 

Our  business  is  to  produce  and  sell  copper.  Prices  are  determined  by  world  markets  over  which  we  have  no 
influence  or  control.  Our  competitive  position  is  primarily  determined  by  our  costs  and  high  grade  copper 
concentrate with low impurities compared to other producers throughout the world and our ability to maintain our 
financial integrity through metal price cycles. Costs are governed to a large extent by the grade, nature and location 
of our Mineral Reserves as well as by input costs and operating and management skills. In contrast with diversified 
mining companies, we focus on copper production, development  and exploration, and are  therefore subject to 
unique competitive advantages and disadvantages related to the price of copper and to a lesser extent, the price 
of our metal by-products. If copper prices increase, we will be in a relatively stronger competitive position than 
diversified  mining  companies  that  produce,  develop  and  explore  for  other  minerals  in  addition  to  copper. 
Conversely, if copper prices decrease, we will be at a competitive disadvantage to diversified mining companies. 

The  mining  industry  is  competitive,  particularly  in  the  acquisition  of  additional  Mineral  Reserves  and  Mineral 
Resources  in  all  phases  of  operation,  and  we  compete  with  many  companies  possessing  similar  or  greater 
financial and technical resources. 

Metal Prices 

The Company’s financial flexibility is highly dependent on the prevailing prices for the commodities it produces. 
While the Company’s strategy is to remain unhedged, circumstances may arise where increased certainty of cash 

14 

 
 
 
flows is considered more important to long term value creation than providing investors short term exposure to the 
volatility  of  metal  prices.  In  these  circumstances,  the  Company  may  elect  to  fix  prices  within  a  contractual 
quotational period or to lock in future prices through the variety of financial derivative instruments available. 

Environmental Protection 

Capstone’s operations (Pinto Valley and Cozamin) and development project (Santo Domingo) are subject to the 
national  and  local  laws  and  regulations  in  respect  of  the  construction,  operating  standards  and  the  eventual 
abandonment  and  restoration  costs  applicable  to  each  location.  Since  the  Cozamin  Mine  is  a  relatively  small 
tonnage, high-grade operation, the overall financial impact of the environmental protection requirements is minor 
relative to our overall financial performance. Each operation is subject to a reclamation and closure cost obligations 
review at year-end to assess the abandonment and restoration cost for the operation at that point. Any changes 
from the previous period are reflected in the balance sheet and could flow through the earnings statement. While 
the financial obligations will increase as disturbance increases, given the relatively modest amounts involved, such 
impacts are likely to be relatively minor from a capital and earnings perspective in the near term. Pinto Valley Mine 
has  a  long  history  of  operations  in  an  established  mining  district  of  Arizona.  As  such,  there  are  significant 
reclamation liabilities. These were reviewed with regulators in 2013 at the time of the acquisition by Capstone and 
were also the subject of a detailed third-party assessment commissioned by the Company in 2015 and have been 
updated to reflect the current mine life. 

In May 2016, Pinto Valley submitted a formal Mine Plan of Operations in support of the Pinto Valley Mine Life 
Extension – Phase 3  (“PV3”) mine plan to the US Forest Service, marking the first step of the permitting process, 
required under the National Environmental Policy Act (“NEPA”). The NEPA process was initiated in January 2017 
after  publishing  a  Notice  of  Intent  to  conduct  an  Environmental  Impact  Statement  (“EIS”).  The  draft  EIS  was 
published for public comment in December 2019. The project is on track and anticipates issuance of a draft Record 
of Decision and final EIS in May 2020, a final Record of Decision in September 2020 and a Notice to Proceed in 
October 2020.Our assets are in mature and stable mining jurisdictions. The environmental protection requirements 
are not expected to be a significant cost or regulatory impediment to carrying on our business. 

Employees 

As of December 31, 2019, Capstone had 1,049 employees and 574 contractors. 

There are approximately 371 hourly employees at the Pinto Valley Mine, a portion of whom are members of six 
unions, and whom are all governed by one collective bargaining agreement negotiated by the United Steelworkers 
Union which is in effect until May 29, 2022. 

Foreign Operations 

Capstone’s material properties  are  in foreign jurisdictions, being the  Pinto Valley Mine (US), and  the Cozamin 
Mine (Mexico). We also have interests in exploration projects. and a mine development project in Chile.  

All of the revenue from continuing operations in 2019 related to foreign operations. Foreign operations represented 
approximately 94% of our assets as at December 31, 2019. 

Social and Environmental Policies 

Capstone places great emphasis on providing a safe and secure working environment for all our employees and 
contractors as we recognize the importance of operating in a sustainable manner. 

Our Values and Ethics – Code of Conduct (“Code of Conduct”) is our Company policy that sets out the standards 
which guide the conduct of our business and the behaviour of our employees, officers and our Board of Directors. 
The Code of Conduct is reviewed annually by the Board. Our Code of Conduct, amongst other things, sets out 
standards in areas relating to: 

•  Promotion and provision of a work environment in which individuals are treated with respect, provided 

15 

 
with equal opportunity and is free of all forms of discrimination; 
•  Zero tolerance policy relating to use of prohibited substances; 
•  Ethical business conduct and legal compliance, including without limitation prohibition against accepting 

or offering bribes; 

•  Commitment to health and safety in our business operations, and the identification, elimination or control 

of  workplace hazards; 

•  Commitment to maintain and improve sound environmental practices in all our activities. 

Capstone’s commitment to sustainable performance is defined in our Integrated Environment, Health, Safety and 
Sustainability  (“EHS&S”)  Policy.  The  Technical,  Health,  Environmental,  Safety  and  Sustainability  (“THES&S”) 
Committee  of  the  Board  has  oversight  of  the  EHS&S  Policy.  Annual  corporate  objectives  for  sustainable 
performance and improvement are approved by the Board and are linked to the objectives and compensation for 
employees at all levels of the organization. We measure our performance against these objectives.  

Capstone regularly reviews and implements internal standards based on industry best practice to ensure continual 
improvement in key areas including health and safety, environmental management, tailings management, energy 
management and social aspects, including stakeholder engagement.

Material Mineral Properties 

Pinto Valley Mine (US) 

The  Pinto  Valley  Mine  is  the  subject  of  a  report  titled  “Pinto  Valley  Mine  Life  Extension  –  Phase  3  (PV3)  Pre-
Feasibility Study” dated February 23, 2016 with an effective date of January 1, 2016. This technical report was 
compiled by Capstone Mining Corp, and authored by Gregg Bush, P.Eng., formerly of Capstone Mining Corp.; 
Tony J. Freiman, PE,  Amec Foster Wheeler  Environment  & Infrastructure, Inc.; Corolla Hoag, CPG, SME-RM, 
SRK Consulting (U.S.), Inc.; Garth Kirkham, P.Geo., FGC, Kirkham Geosystems Ltd.; Kenneth W. Major, P.Eng., 
KWM Consulting Inc.; and  John  Marek,  PE,  SME-RM, Independent Mining Consultants, Inc.,  each  a Qualified 
Person  as  defined  by  NI  43-101.  The  description  of  the  Pinto  Valley  Mine  in  this  document  is  based  on 
assumptions, qualifications and procedures which are set out in the PV3 PFS. Reference should be made to the 
full text of this report, which is available in its entirety on SEDAR at www.sedar.com under Capstone’s profile. The 
scientific and technical information below which is not contained in these reports has been reviewed and approved 
by Claydon Craig, P.Eng., Superintendent of Mine Technical Services at our Pinto Valley Mine and a Qualified 
Person under NI 43-101. 

Description and Location 

The property is located at the west end of the Globe-Miami mining district, approximately 130 km east of Phoenix 
and 10 km west of the town of Miami, in Gila County, Arizona, at 33°23’32”N and 100°58’15”W. The Pinto Valley 
property consists of approximately 5,130 ha of contiguous claims. These comprise 69 patented lode mining claims, 
53 patented mill sites, 451 unpatented lode mining claims and mill sites, and seven parcels of fee (private) land. 

Capstone  acquired  the  Pinto  Valley  Mine  and  associated  railroad  operations  (San  Manuel  Arizona  Railroad 
Company) on October 11, 2013 for a cost of $650 million. A 2% NSR applies to 26 of the unpatented mining claims 
that are not in the current mine plan. 

Pinto  Valley  is  an  open  pit  mine  producing  copper  and  molybdenum  concentrates  and  copper  cathode.  The 
administration, ore processing, tailings, waste rock storage, and maintenance facilities are located on the property, 
in close proximity to the pit. The processing facility consists of three crushing stages, ball mills, copper flotation 
stages,  a  molybdenum  flotation  circuit,  and  associated  thickeners  for  concentrates  and  tailings.  Two  tailings 
storage  facilities  (“TSF”)  are  currently  operational  (Figure  1)  and  two  former  tailings  facilities  are  no  longer  in 
service but remain part of our on-going inspection, maintenance and surveillance program. Pinto Valley also has 
an  SX/EW  facility  that  processes  pregnant  leach  solution  from  low  copper  grade  material  that  is  leached.  The 
SX/EW accounts for less than 5% of production. 

16 

 
Pinto Valley has an inspection, maintenance and surveillance program in place to ensure that its tailings storage 
facilities continue  to  perform safely and as  intended.  The  Engineer  of Record (“EOR”) for the TSFs  is Tony J. 
Freiman, PE of Wood Environment & Infrastructure Solutions, Inc. The EOR is responsible for the design of the 
active TSFs and provides guidance on construction and operational practices. Pinto Valley site personnel monitor 
performance  of  the  active  TSFs  daily  and  prepare  weekly  and  monthly  internal  reports  for  Pinto  Valley  Mine 
management and engineering groups. Pinto Valley site personnel communicate with the EOR at least weekly. The 
EOR performs a formal on-site inspection of the active TSFs each quarter and the inactive TSFs annually. Ad-hoc 
on-site inspections by the EOR occur approximately every month. A report is prepared by the EOR for each of the 
formal inspections with a summary of the TSF performance, and recommendations are provided for current and 
future work as appropriate. Approximately every 3 years, an independent third party reviews the work performed 
by the EOR and the performance of the active and inactive TSFs. The most recent independent third-party review 
was completed in January 2018 by Haley & Aldrich, Inc. 

Environmental  liabilities  at  the  Pinto  Valley  Mine  relate  to  the  heap  leach  facility,  tailings  impoundments  and 
associated engineered containment infrastructure, waste rock dumps, surface water containment structures, as 
well  as  the  removal  of  all  operational  infrastructures.  A  closure  and  post-closure  strategy  and  a  mined  land 
reclamation plan detailing methods and costs associated with restoring the site to an acceptable environmental 
standard were most recently approved in 2019 and 2016 respectively. Surety Bonds totaling $118.6 million have 
been filed with the Arizona Department of Environmental Quality (“ADEQ”) and the Arizona State Mine Inspector 
in  accordance  with  the  mandate  of  these  agencies  and  associated  regulations  and  policies.  These  financial 
security amounts represent the estimated interim closure and post-closure costs through 2023 for ADEQ-permitted 
facilities  and  through  2026  for  surface  reclamation  overseen  by  the  State  Mine  Inspector,  on  an  undiscounted 
basis. Amounts are reviewed with each significant change in the mine plan or closure measures. 

The  Pinto  Valley  Mine  requires  16  permits  granted  from  various  state  and  federal  agencies;  operations  of  the 
railroad requires five permits mainly from the State of Arizona. Pinto Valley Mine has all the necessary permits to 
conduct mining activities with the exception of consolidation/renewal of existing U.S. Forest Service (“USFS”) land 
use authorizations (Plan of Operations). Pinto Valley Mine is presently working with the USFS to develop an interim 
and a long-term renewal of its land use authorizations. An interim plan for existing disturbances to forest land will 
increase the reclamation bond by approximately $3.35 million. The consolidated Plan of Operation was submitted 
to the USFS and deemed complete in 2016. Once approved, the Plan of Operations includes tailings storage on 
USFS land to accommodate the PV3 mine plan.  

Accessibility, Climate, Local Resources, Infrastructure and Physiography 

The Pinto Valley Mine is accessed from US Highway 60 (“US 60”), then 5 km on paved Forest Road (“FR”) 287. 
The site can also be  accessed from Tucson, Arizona (160 km to the south) by travelling  north on State Route 
(“SR”) 77. The mine is 10 km west of Miami, a town of approximately 1,800 residents, and 18 km west of Globe, 
the County seat, with approximately 7,500 residents. Because of a long-standing mining tradition in the area, many 
local services are in place to supply the mine's needs, with the remaining services coming from the greater Phoenix 
area. Medical facilities are available in Miami. Fire, police, public works, transportation and recreational facilities 
are in place and fully functioning. 

Pinto  Valley  Mine’s  moderate,  semi-arid  regional  climate  allows  for  year-round  operation.  The  average  annual 
precipitation is 480 mm. May and June are typically the driest months of the year and may result in local drought 
conditions.  

Pinto  Valley  Mine  has  sufficient  surface  rights  for  mining  operations,  mineral  processing  facilities  and  tailings 
storage  to  mine  the  pushbacks  until  2026,  as  described  in  Capstone’s  “Pinto  Valley  Mine  2014  Pre-Feasibility 
Study” dated April 28, 2014 with an effective date of January 1, 2014 (“PV2 PFS”). The expanded PV3 PFS mine 
plan will require permit amendments. Off-site infrastructure includes the incoming electric power generation and 
transmission capacity provided by the Salt River Project, the local highway system provided by state and federal 

17 

 
governments,  the  local  transportation  services  provided  by  various  contractors,  and  the  telephone  and  data 
communications systems.  

Tailings are deposited in existing permitted tailings storage facilities. Tailings Dam No. 4 is the primary storage 
facility, with Tailings Dam No. 3 used during maintenance activities at Tailings Dam No. 4 (Figure 1). Pinto Valley 
Mine has several water sources including 
a  private  wellfield  with  three  wells,  a 
pipeline network connecting it to several 
neighboring  mines,  a  system  of  water 
catchments  with  pumpback  capabilities, 
and 
reclaim  systems  on  operating 
tailings impoundments however, periodic 
drought remains a risk.  

The Pinto Valley Mine is located in east-
central Arizona in the structural transition 
zone between the Sonoran section of the 
Basin and Range physiographic province 
to 
the 
the  south-southwest,  and 
Colorado  Plateau  to  the  north.  The 
terrain surrounding the mine is generally 
mountainous,  dominated  by  sharp 
landforms  and  prolific  exposures  of  a 
variety of bedrock formations present in 
the  region.  The  Pinto  Valley  Mine  is 
the  Pinto  Creek 
entirely  within 
watershed, where local elevations range 
from  about  900  m  to  1,500  m  above 
mean sea level. 

The  Pinto  Valley  Mine  is  near  the 
boundary of areas mapped as the Interior 
Chaparral  biotic  community  and  the 
Arizona  Upland  subdivision  of  Sonoran 
Desert scrub biotic community, with plant 
species on the property characteristic of 
each group. Most of the animal species 
observed  have  wide  environmental 
tolerances  and  are  present  in  both  plant 
communities on the property. 

History 

FIGURE 1: 
PINTO VALLEY INFRASTRUCTURE AND LOCATION OF OPEN PIT 

The Globe-Miami district is one of the oldest and most productive mining districts in the United States, with its first 
recorded production occurring in 1878. Since that time, more than 15 billion pounds of copper have been produced 
in the Globe-Miami mining district. Prior to the construction of Pinto Valley Mine, a chalcocite-enriched zone of the 
deposit was mined from 1943 until 1953 as the Castle Dome underground mine. 

The Pinto Valley open pit mine and concentrator went into production in 1974. The SX/EW plant began processing 
PLS  from  the  leach  dumps  in  1981.  In  February  1998,  mining  and  milling  operations  were  suspended  and 
environmental  permits  were  maintained  during  the  suspension  of  operations,  as  were  the  water  and  electrical 
systems. SX/EW facilities and cathode copper production continued during the suspension of mining and milling 
operations. 

18 

 
The mine has had two restarts since the 1998 shutdown. The mine resumed sulphide operations in mid-2007 for 
18 months to January 2009 and then went into care and maintenance with only leaching operations continuing. 
The second restart began in December 2012 and included extensive rehabilitation of the site and purchase of a 
new mining fleet. 

Ownership  of  Pinto  Valley  has  changed  numerous  times  since  its  inception.  At  the  time  of  construction  and 
commissioning, it was owned by Cities Service Company, who had recently merged with Tennessee Corporation. 
Occidental Petroleum Corporation acquired Cities Service Company in late 1982 and sold the Miami operations 
to Newmont Mining Corporation in 1983. At this time, the company's name was changed to Pinto Valley Copper 
Corporation. In 1986, Newmont merged the Pinto Valley Copper assets into Magma Copper Company holdings, 
and Pinto Valley Copper became the Pinto Valley Mining Division of Magma Copper Company. In 1995, Broken 
Hill Proprietary Company Limited purchased Magma Copper Company. With the merger of Broken Hill Proprietary 
Company Limited and Billiton in 2001, the Pinto Valley Mining Division became Pinto Valley Operations of BHP 
Copper  Inc.  (“BHP  Copper”).  In  2013,  Capstone  purchased  Pinto  Valley  Operations,  now  referred  to  as  Pinto 
Valley Mine or Pinto Valley. 

Pre-2006  Pinto  Valley  drilling  programs  comprised  a  combination  of  core,  rotary,  and  churn  drillholes.  Drilling 
documentation was limited to BHP Copper internal reports and lacked descriptions for pre-2010 procedures. Churn 
holes defined much of the early Castle Dome mineralization, which has been mined out. Drilling since the 1986 
block  model  includes  10  core  holes  and  3  Reverse  Circulation  (“RC”)  rotary  holes  drilled  in  1992.  From  the 
beginning of 1996 to April 1997, 67 RC exploration and infill holes were drilled: 48 RC holes drilled in 1996, and 
19  RC  holes  drilled  in  1997.  The  1997  holes  were  drilled  in  the  interior  pit  and  through  the  Gold  Gulch  and 
Continental faults. Seven of the exploration holes were drilled east of the existing pit and laid the ground work for 
future plans of an east pit expansion. All drillhole collar locations were surveyed. The majority of the drillholes are 
vertical  and,  therefore,  do  not  have  downhole  surveys.  However,  most  inclined  holes  have  downhole  surveys. 
From 2006 through 2008, there were drilling campaigns with various purposes, including delineation, exploration, 
geotechnical, and resource classification upgrade drilling. These include 39 drillholes in 2007 and 62 drillholes in 
2008. Diamond drillhole programs in 2010 focused on exploration, while those in 2011 and 2012 focused on infill 
drilling for resource classification upgrade in support of restarting operations. Ten holes were drilled in 2010, 40 
holes were drilled in 2011, and 64 holes were drilled in 2012. In 2013 BHP Copper drilled 12 in-pit infill diamond 
drillholes totaling 2,853 m, to close the drillhole spacing grid and 64 in-pit RC drillholes totaling 3,380 m to help 
characterize  the  mineralization  directly  beneath  working  levels  of  the  mine.  All  drillhole  logging  data,  including 
collar,  survey,  assay,  lithology,  alteration,  and  mineralization  data  were  entered  into  an  acQuire™  structured-
query-language (“SQL”) database system. All sample data were tagged and tracked using bar codes, which linked 
all assay information provided by the laboratory to the database, including the QAQC. The system was secured 
by BHP Copper using stringent protocols and procedures. Deviations and discrepancies from sample  dispatch 
reports were reported and investigated. 

A number of different companies and laboratories provided assay services to Pinto Valley over the years. Details 
of  sampling  and  assaying  procedures  used  during  the  earlier  stages  of  operation  are  not  readily  available. 
Procedures used by outside labs that ran assays for some of the later drilling campaigns, such as those performed 
by Mountain States for the 1992 holes and Chemex for the 1996 holes, are also not readily available. The analytical 
procedures were in line with industry standards for total copper analyses, but BHP Copper-specific procedures 
were used to determine acid soluble copper concentrations. These involved digestion with 10% sulphuric acid, 
followed by placement in a hot bath at 40°C, and read after 40 minutes. 

Independent  audits of  the  Pinto  Valley assays were conducted in 1992  and  2000. Results indicated the assay 
values in the Pinto Valley database have been reliably entered and that total copper assays in the Pinto Valley 
database were reproducible and could be considered representative within normally-accepted error limits. 

As  part  of  BHP’s  start-up  Feasibility  Study  done  in  2006,  a  QAQC  program  was  conducted  on  101  randomly 
selected drillhole assay interval pulp samples and 15 randomly selected drill core assay intervals. Samples were 

19 

 
sent to  Skyline Assayers and  Laboratories Inc. (“Skyline Labs”) in Tucson,  Arizona for total copper  and acid-
soluble copper analyses. Skyline Labs was instructed to analyze the samples for acid soluble copper using BHP 
Copper  lab  procedures.  Certified  reference  material  standards  from  the  National  Institute  of  Standards  and 
Technology (“NIST”) were inserted in sequential order for analysis preceding the 15th pulp sample in the analytical 
run. The results indicated that historical quality control measures used in the Pinto Valley Mine analytical laboratory 
were variable. At times they were extremely good, but at others they were less so, although still acceptable. 

BHP  Copper  undertook  surface  mapping  to  provide  additional  data  throughout  the  identification  and  selection 
phases  of  the  PV2  mine  planning  project.  Two  drilling  campaigns  were  conducted  on  separate  occasions  to 
improve  both  the  geotechnical  and  geometallurgical  knowledge  of  the  deposit.  The  surface  mapping  for 
geotechnical information focused primarily on the bedding planes, major structures, and overall geological strength 
index. Various ore-types were confirmed using surface mapping and by reviewing core logs. Alteration zones and 
ore-types were identified in the pit wall and correlated against core samples taken in previous drill campaigns. 
Descriptions from the core logs were used to plot the correlation between rock type and alteration zone. The most 
important ore types were narrowed down to Ruin granite, quartz monzonite, and diabase. These ore types are 
based on relative abundance, gangue mineralogy, copper grade, alteration, and the potential impact on overall 
production (recovery, throughput, and consumption of reagents/energy). Capstone relied extensively on the BHP 
Copper’s PV2 project data to complete the Capstone PV2 PFS. The data provided by BHP Copper was reviewed 
by the QPs in the Capstone PV2 PFS to ensure it was applicable and sufficiently detailed to form the basis of 
assumptions in the study. Additional work was conducted where data gaps were found, including field mapping 
for pit wall geotechnical analysis, geotechnical drilling for tailings impoundment design and metallurgical testing to 
validate previous test results. 

Geological Setting 

The  Globe-Miami  mining  district  of  central  Arizona  includes  porphyry  copper-molybdenum  (“Cu-Mo”)  deposits 
associated with Paleocene Epoch granodiorite to granite porphyry stocks (65-59 million years ago). Vein deposits 
and possible exotic copper deposits are also found within the district. 

Precambrian basement rocks throughout southern Arizona and New Mexico largely consist of early Proterozoic 
Pinal Schist (~1,700 million years old) intruded by granites correlative with two-mica granite batholiths (~1,450 
million years old). At the Pinto Valley Mine this is represented by the Ruin granite (also referred to as the Lost 
Gulch quartz monzonite) that hosts the Cu-Mo mineralization. The Late Proterozoic-aged (~1,420-1,150 million 
years  old)  Apache  group,  comprising  conglomerate,  limestone,  quartzite,  and  minor  basalt  units  overlying  the 
basement  rocks,  was  intruded  by  1,150  million  years  old  Apache  diabase  sills  of  varying  thicknesses.  These 
diabase units are represented at the Pinto Valley Mine as thin dikes and sills, and commonly contain higher copper 
concentrations  than  the  surrounding  Ruin  granite.  During  the  Paleozoic  Era,  various  limestone  units  were 
deposited representing the shallow, marine environment present over much of the southwestern US at the time. 

Subduction  of  the  Farallon  tectonic  plate  (80-50  million  years  ago)  off  the  west  coast  of  the  southwestern  US 
initiated arc magmatism responsible for generating the Cu-Mo-bearing intrusions in the region. Stocks emanating 
from  the  Schultze  granite,  the  source  of  the  mineral-bearing  fluids  to  the  Globe-Miami  mining  district,  were 
emplaced at the Pinto Valley Mine between 60-59 million years ago. 

Regional Tertiary-Era Basin and Range  extension  and faulting following cessation of subduction facilitated the 
dismemberment,  tilting,  and  exposure  of  the  Cu-Mo  deposits.  They  were  preserved  through  deposition  of  the 
Whitetail conglomerate (Oligocene Epoch) and the Apache Leap tuff (Miocene Epoch). Further extension in the 
Pliocene Epoch deposited the Gila conglomerate into basins. 

The Pinto Valley Mine deposit is bound by faults that vary in age from the Pre-Cambrian to the Tertiary. These 
have  controlled  the  emplacement  of  the  Ruin  granite,  stocks  of  the  Cu-Mo-bearing  Schultze  Granite,  and 
subsequent post-mineralization Basin-and-Range extensional faulting.

Exploration 

Capstone is not currently exploring the Pinto Valley property due to the large resource already identified, of which 
33%  are  Mineral  Reserves,  resulting  in  a  mine  life  to  2039.  Additional  Mineral  Resources  could  potentially  be 
brought  into  the  Mineral  Reserves  in  the  future  through  operational  improvements,  cost  reductions,  and/or 
increased metals prices. 

Mineralization 

The primary sulphide minerals encountered at the Pinto Valley Mine are chiefly pyrite and chalcopyrite with minor 
amounts of molybdenite. Gold and silver are recovered as by-products when material containing sulphide minerals 
is processed. Sphalerite and galena occur locally in very small amounts. Alteration of silicate minerals of the host 
rocks to other groups of minerals due to the presence of hydrothermal fluids associated with the Cu-Mo-bearing 
intrusive rocks include potassic, argillic, sericitic, and propylitic alteration suites. 

Sulphide  minerals  generally  occur  in  veins  and  microfractures  and  less  abundantly  as  disseminated  grains, 
predominantly in biotite sites. The ore zone grades outward into a pyritic zone with higher total sulphide content. 
Molybdenum distribution generally reflects copper distribution, with higher molybdenum values usually found in 
the higher-grade copper zones. Oxide mineralization and a supergene enrichment blanket was developed at the 
Pinto Valley Mine, but these areas have since been mined. 

Sulphide deposition at Pinto Valley is controlled to some extent by the host rock. The sulphide content decreases 
in  Precambrian  aplite  intrusions.  Aplite  usually  contains  less  than  0.25%  copper,  whereas  adjacent  Quartz 
Monzonite may have as much as 0.6% copper. The deficiency of copper in aplite is probably due to the absence 
of biotite, which makes up about 7% of Quartz Monzonite. Disseminated chalcopyrite shows an affinity for biotite, 
where it is disseminated through the biotite or partially replacing it. Additional chalcopyrite is also present in veins 
cutting both rock types. 

Drilling 

Recent drilling incorporated into the April 2019 Mineral Resource model consists of ten geotechnical holes in 2014, 
43 infill RC holes and three geotechnical holes in 2015, four infill RC holes in 2016, 17 infill RC holes and one 
RC/core hole in 2017, 4 RC holes and 1 core hole in 2018 and, in 2019, 4 RC holes and 1 core hole.  

Sampling and Analysis 

Pinto Valley uses RC and diamond drillcore samples for Mineral Resources estimates. The majority of drilling is 
vertical with spacing commonly between 200ft and 400ft. Capstone employees and contractors are responsible 
for all on-site sampling of drill core and drill cuttings. Typical sample intervals are 10 feet. Drillcore samples are 
split  by  core  saw  and  placed  in  marked  bags  and  shipped  to  accredited  external  laboratories  for  sample 
preparation and analysis for copper, acid soluble copper, and molybdenum. A total of 94,328 RC and diamond 
drillhole samples were used for the April 2019 Mineral Resources estimate. 

Sample quality of drillhole samples is monitored through regular insertion of reference material standards, blanks, 
and  duplicate  samples.  Certified  reference  material  (CRM)  standards  are  purchased  commercially,  and  in 
November  2017,  CRM  standards  were  also  created  from  PV  material.  QAQC  procedures  include  real-time 
monitoring of quality control data, thresholds for sample failures and sample batch reanalysis, and regular monthly 
reporting. QAQC results demonstrate that drillhole assay values are accurate, repeatable, and free from cross-
contamination. 

Database validation work comprises a check of 10% of all new records entered into the database. This includes 
verification  of  collar,  downhole  survey,  lithology,  and  assay  data.  The  most  recent  database  validation  was 
completed in April 2018.  

21 

 
Security of Samples 

Only employees and contractors are permitted in the core logging facility when unsampled drillcore is ready to be 
cut and prepped RC cuttings and core are awaiting transport. A transmittal form which identifies the batch number 
and the corresponding sample number series is emailed to the external laboratory. The samples are delivered to 
the external laboratory by a laboratory representative transporting from site to laboratory. 

Core and chip samples are stored on-site at a dedicated core storage facility. 

Mineral Resource and Mineral Reserve Estimates 

The April 2019 Mineral Resource estimate for Pinto Valley mineralization was completed by Pinto Valley’s Chief 
Geologist  and  Qualified  Person,  Klaus  Triebel,  CPG.  The  Mineral  Resources  were  estimated  using  accepted 
industry standards conforming to NI 43-101 requirements. Surfaces and solids were created by Pinto Valley Mine 
staff for the lithology and mineralization domains,  and major faults. Drillhole samples were composited downhole 
to 13 m (45 feet) length to match the selective mining unit (“SMU”) bench height and to reduce the influence of 
typically  narrow,  very  high-grade  samples.    Thirteen  lithology  units  were  defined  as  domains,  honouring  fault 
traces;  these  domains  were  considered  as  hard  boundaries  during  estimation.  Nine  sub-domains  based  on 
mineralization  trends  were  modelled,  with  6  forming  soft  boundaries  where  grade  can  be  informed  by  nearby 
samples located in an adjacent domain and 3 formed hard boundaries. Ordinary kriging (“OK”) was applied in all 
domains for the Cu estimation. To control the influence of high-grade Cu samples when estimating block grades, 
a combination of top-cutting and outlier search restriction was applied, with the resulting contained copper being 
within 1% of an uncapped model. For molybdenum (“Mo”), top cutting was not applied. Density was estimated in 
the April 2019 model using 300 density tests covering the five most important lithologies and 16 alteration types. 
The average estimated density for ore-grade mineralized rock, primarily Ruin Granite, is 2.61 t/m3. Grade variability 
is low, with nugget effects of less than 25% for both copper and molybdenum. The block model grades for copper 
and molybdenum were estimated using OK into blocks that were 30 m Easting × 30 m Northing × 14 m Elevation 
(100 ft × 100 ft × 45 ft) in size. During grade estimation, search orientations were designed to follow the general 
trend of the mineralization  in each  of the structural domains. The estimation plan for most domains involved a 
single search pass using a minimum of 2 composites and a maximum of 8 composites, with a maximum of 3 from 
any single drillhole. Confidence classification was modified slightly from 2018,  by adjusting the average maximum 
distances to the closest two or three holes based on variography. 

The reported Mineral Resources in Table 1 are based on the April 2019 Mineral Resources estimate completed 
by Klaus Triebel, CPG., and reflect the mined topographic surface as at December 31, 2019. Mineral Resources 
are reported above a 0.17% Cu cut-off grade within a reasonable economic prospects pit that use the following 
parameters: $3.30/lb Cu, $10.00/lb Mo, 88% Cu recovery, 50% Mo recovery, $1.50/ton mining costs, $1.50/ton 
G&A  costs,  $5.00/ton  milling  costs,  and  a  pit  slope  angle  of  45°.  Mineral  Resources  are  reported  inclusive  of 
Mineral  Reserves, and Mineral Resources that are not Mineral Reserves do not  have demonstrated economic 
viability. Contained metals are reported at 100%.

NOTE: Klaus Triebel, CPG., Chief Geologist at Pinto Valley, is the Qualified Person responsible for the Pinto Valley Mineral 
Resources estimate. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Mineral 
Resources are presented inclusive of Mineral Reserves. Mineral Resources are reported as at December 31, 2019 above a 
0.17% Cu cut-off grade. The economic assumptions for the reasonable prospects pit include: $3.30/lb Cu, $10.00/lb Mo, 88%

The Mineral Reserve pit design was developed by John Marek, PE, President of Independent Mining Consultants, 
Inc.  (“IMC”).  Claydon  Craig,  P.Eng.,  estimated  Mineral  Reserves  in  accordance  with  industry  guidelines  by 
tabulating the contained measured and indicated (Proven and Probable) material inside of the designed pit. The 
schedule utilizes a variable cut-off grade to the mill that fluctuates between 0.17 to 0.18 % Cu, resulting in a low-
grade stockpile that is processed at the end of the mine life. Stockpile material is included in the Mineral Reserve. 
The final pit design and the Mineral Reserve do not include the low-grade leach dump material in the economic 
analysis  or  Mineral  Reserve.  The  Mineral  Reserves  design  was  completed  at  $2.75/lb  copper  and  $12.50/lb 
molybdenum. The effective date of the Mineral Reserve is January 1, 2020. Claydon Craig, P.Eng., oversaw the 
production depletion of the Mineral Reserves model. To simplify the Mineral Reserve reporting process, the cut-
off  grade  was  changed  from  the  variable  0.17-0.18%  Cu  to  0.175%  Cu.  This  cut-off  closely  approximates  the 
reported Mineral Reserves and will be used going forward.

Mining Operations 

Run-of-mine ore is crushed through the primary crusher and conveyed to the fine crushing plant for further size 
reduction. The fine-crushed ore is fed to a conventional grinding and flotations circuit to produce a bulk copper 
concentrate  and  molybdenum  concentrate.  The  concentrates  are  thickened  and  filtered  to  produce  products 
suitable for transport. Tailings are thickened and deposited in one of the two active tailings storage facilities (TSF3 
and TSF4). Low-grade mineralization is leached and the pregnant solution is processed through an SX/EW plant 
that exists on the property. However, no additional low-grade ore is being placed under leach in accordance with 
the mine plan. 

The copper concentrates and cathodes produced from Pinto Valley Mine is sold to smelters and traders. The high 
quality of the concentrates makes it sought after by both smelters and traders. Pinto Valley has well-established 
environmental  protocols  that  adhere  to  federal  and  state  regulatory  requirements  and  to  internal  corporate 
guidance to reduce impacts to the environment. Pinto Valley is subject to environmental regulations addressing 
groundwater; surface water; storm water management; air quality; well installation; water withdrawal from state 
aquifers; waste handling and disposal; handling and storage of toxic substances; surface reclamation; and cultural 
and biological resources. The Pinto Valley Mine has all the necessary permits to conduct mining activities through 
2026 with the exception of the consolidated Plan of Operations that is currently under review by the USFS. The 
consolidated Plan of Operations is a compilation of prior authorizations and encroachments on federal lands. 

The Pinto Valley Mine’s applicable taxes include the following: 

•  Corporate Taxes – The Tax Cuts and Jobs Act signed into law on December 22, 2017 significantly reformed 
the US tax system. Effective for the 2019 taxation year, the combined US Federal and Arizona state corporate 
income tax is calculated at a blended 21% rate applied on taxable income. The Alternative Minimum Tax was 
permanently repealed. Arizona allocates taxable income based on sales to customers in the state and Pinto 
Valley does not expect to have sales in Arizona in the foreseeable future.   

•  The  Arizona  state  severance  tax  on  metalliferous  minerals  is  charged  at  a  2.5%  rate  on  50%  of  the 

difference  between the gross value of production and production costs. 

23 

 
•  The  Arizona  Department  of  Revenue  exercises  general  supervision  over  county  assessors  in 
administering the property tax laws to ensure that all property is uniformly valued for property tax purposes. 
Gila County tax authorities are responsible for the billing and collection of property taxes. 

Exploration and Development 

We do not currently have any planned exploration activities at the Pinto Valley Mine but from time to time we do 
undertake  in-pit  drilling  to  better  define  Mineral  Reserves  for  short-term  planning  purposes.  This  data  is  then 
incorporated  periodically  into  the  Mineral  Resource  block  model.  Our  development  activities  are  focused  on 
execution of the PV3 mine plan. 

Cozamin Mine (Mexico) 

The Cozamin Mine is the subject of a report titled “Technical Report on the Cozamin Mine, Zacatecas, Mexico” 
dated January 24, 2019 with an effective date of October 24, 2018 (the “Cozamin Report”). This technical report 
was  prepared  by  Gregg  Bush,  P.Eng.  former  COO  of  Capstone  Mining  Corp.;  Jenna  Hardy,  P.Geo.,  Nimbus 
Management Ltd.; Tucker Jensen, P.Eng., Capstone Mining Corp.; Darren Kennard, P.Eng., Golder Associates 
Ltd.; Garth Kirkham, P.Geo., FGC, Kirkham Geosystems Ltd.; Chris Martin, CEng MIMMM, Blue Coast Metallurgy 
Ltd.; Vivienne McLennan, P.Geo., Capstone Mining Corp. and Humberto Preciado, PhD, P.E., Wood Environment 
& Infrastructure Solutions, Inc., each a Qualified Person as defined by NI 43-101. Reference should be made to 
the full text of this report, which is available in its entirety on SEDAR at www.sedar.com under Capstone’s profile. 

All scientific and technical information in this summary relating to any updates to the Cozamin Mine since the date 
of the Cozamin Report, other than the Mineral Resource and Mineral Reserve estimates, has been reviewed and 
approved by Qualified Persons who supervised the preparation of updates to elements of the Cozamin Report. 
These Qualified Persons include those listed in Interests of Experts in this Annual Information Form. 

Project Description and Location 

The Cozamin Mine is an operating polymetallic mine with a 3,990 tonne per day milling capacity, located in the 
Morelos  Municipality  of  the  Zacatecas  Mining  District,  near  the  south-eastern  boundary  of  the  Sierra  Madre 
Occidental Physiographic Province in North-central Mexico. The mine and processing facilities are located near 
coordinates 22° 48’ N latitude and 102° 35’ W longitude on 1:250,000 Zacatecas topographic map sheet (F13-6). 
Currently,  91  Cozamin-owned  concessions  cover  4,210  hectares.  Capstone  acquired  these  concessions  in 
January 2004, which is 100% owned by Capstone, subject to a 3% NSR payable to Grupo Bacis S.A. de C.V., a 
Mexican resource company. Mineral claims acquired in September 2009 from Minera Largo S de RL de CV, a 
wholly owned subsidiary of Golden Minerals Company (“Golden Minerals”), are subject to future cash payments 
of a NSR of 1.5% on the first one million tonnes of production and cash payments equivalent to a 3.0% NSR on 
production in excess of one million tonnes from the acquired claims. The NSR on production in excess of one 
million tonnes also escalates by 0.5% for each $0.50 increment in copper price above $3.00 per pound of copper. 
In 2014, we acquired 45 additional concessions from Golden Minerals totalling 775 ha that surround the Cozamin 
Mine’s existing concessions. A total of 17 of the claims are subject to a finder’s fee to be paid as a 1.0% NSR or 
Gross  Proceeds  Royalty  to  International  Mineral  Development  and  Exploration  Inc.  pursuant  to  existing 
agreements on the concessions dating back to October 1994 and August 2000.  

In 2017, Capstone entered into an agreement with  Endeavour Silver Corp. (“Endeavour”) allowing for the  two 
companies to exchange access to certain of each other’s mining concessions that abut at the southern boundary 
of Capstone’s Cozamin Mine property. The agreement provides Capstone with exploration and exploitation rights 
on  the  Endeavour  concessions  below  2,000  metres  above  sea  level  (masl),  a  depth  where  copper-rich 
mineralization has been historically found and mined by Capstone and provides Endeavour with exploration and 
exploitation  rights  on  the  Capstone  concessions  above  2,000  masl,  where  more  precious-metal  dominant 
mineralization  has  historically  been  mined,  in  the  historic  Zacatecas  district.  The  agreement  provides  for  both 
parties to share information on the concession covered by the agreement and to jointly have access to explore for 
and  exploit  mineralization  appropriate  to  each  company’s  core  business;  being  base  metals  for  Capstone  and 

24 

 
precious metals for Endeavour. In certain instances, it also provides for a 1% NSR royalty for the entity electing 
not to produce. Additionally, and under certain well-defined circumstances, it provides flexibility around the 2,000 
masl division.  

The  Cozamin  property  requires  payment  of  mining  duties  to  the  Secretaria  de  Economía  on  the  mining 
concessions semi-annually in January and July, plus annual land payments for surface use. Mining duties totaled 
$64,167 in 2017,  $77,726 in 2018 and $91,889 in 2019. 

The Cozamin Mine lies within a regionally mineralized area that has seen extensive historic mining over more than 
475  years.  Host  rocks  surrounding  the  mineralized  vein  systems  are  anomalous  in  base  and  precious  metals, 
providing  a  detectable  halo  of  elevated  metal  values  that  extends  a  considerable  distance  beyond  the  known 
workings. Numerous old mine workings, excavations and dumps, and historic tailings are present, both on, and 
adjacent to, the Cozamin mine site; some lie on mining lands held by Capstone and others are held by third parties. 

Cozamin Mine has an inspection, maintenance and surveillance program in place to ensure that its TSF continues 
to perform safely and as intended. Humberto Preciado, PE, of Wood Environment & Infrastructure Solutions, Inc., 
is  the  EOR,  Engineer  of  Record,  for  Cozamin’s  TSF.  The  EOR  is  responsible  for  the  design  of  the  TSF  and 
provides guidance on construction and operational practices. Cozamin Mine personnel monitor performance of 
the TSF daily and prepare weekly and monthly internal reports for site management and engineering groups. The 
EOR reviews the site reports monthly. At least three times per year, a representative from the EOR’s firm, performs 
an inspection of the TSF, including one or two inspections per year by the EOR. Annually, the EOR summarizes 
TSF  performance  and  operational  practices,  and  provides  recommendations  for  current  and  future  work. 
Approximately  every  2  years,  an  independent  third  party  reviews  the  work  completed  by  the  EOR  and  the 
performance  of  the  TSF.  The  most  recent  independent  third-party  review  was  completed  in  February  2018  by 
Norwest Corporation. 

Prior  to  Capstone’s  involvement  in  the  Cozamin  Mine,  several  environmental  studies  had  been  carried  out  by 
previous owners. As the San Roberto Mine, the Cozamin Mine was previously fully permitted to operate at 750 
tpd. Capstone formally received its operating permit on October 20, 2006. This is known in Mexico as a Licencia 
Ambiental Única (“LAU”). A LAU for a throughput expansion to 2,600 tpd was received on March 25, 2008. On 
January 19, 2009, application was made to modify the LAU to expand throughput to 3,000 tpd, which was granted 
in May of that year. In January of 2011, further application was made to increase the permitted throughput from 
3,000 tpd to 4,000 tpd, which was granted in November of 2011. The permit to operate at throughput up to 4,500 
tpd capacity was granted in June 2015. 

The Cozamin Mine’s Mineral Resources and Mineral Reserves are situated within a mineralized vein/fault structure 
known  as  the  Mala  Noche  Vein  (“MNV”)  that  strikes  east-west  and  dips  to  the  north.  This  structure  hosts  the 
copper-rich San Roberto zone and adjacent to the east, the zinc-rich San Rafael zone. In 2010, we discovered 
the MNFWZ, a vein splay off the MNV vein on the footwall side oriented northwest-southeast. Capstone is currently 
exploring for extensions to mineralization found at MNV, San Rafael, and MNFWZ. Figure 2 illustrates the location 
of project infrastructure and the surface projection of the MNV.  

Environmental  studies  have  shown  that  flotation  tailings  and  some  types  of  waste  rock  have  the  potential  to 
generate  acidic drainage. In addition, construction activities as a part  of the  expansions have  already reduced 
identified  sources  of  acidic  drainage  associated  with  the  historic  tailings  impoundment  as  well  as  downstream 
contamination due to tailings spills by previous operators. An environmental management and monitoring program 
is  currently  underway  and  will  be  ongoing  for  the  life  of  the  mine.  Data  collected  are  being  used  to  define  an 
operational  environmental  management  and  monitoring  program,  which  will  include  appropriate  environmental 
management and mitigation plans based on the principle of continuous improvement. These will be reviewed and 
revised as necessary, on at least an annual basis, with results reported as required to Mexican regulators.

Other issues of environmental concern relate to potential impacts comparable to those in underground mines of 
similar size with flotation tailings impoundments. These include: dust, tailings handling/management, storm water 
diversion, combustibles and reagent management/handling, waste management and disposal and noise. Work to 
date indicates that environmental impacts are manageable. Cozamin was awarded the Clean Industry Certification 
from Mexico’s Federal Attorney for Environmental Protection (Procuraduría Federal de Protección al Ambiente or 
PROFEPA) for the third time in July 2018 for this management process and best practices and procedures. The 
Clean Industry Certification is valid until July 2020.

COZAMIN INFRASTRUCTURE AND LOCATION OF MINERAL RESOURCES AND RESERVES. 

Accessibility, Climate, Local Resources, Infrastructure and Physiography 

The Cozamin Mine is located 3.6 km to the north-northwest of the city of Zacatecas, the Zacatecas state capital. 
The  municipality  of  Zacatecas  has  a  population  of  approximately  138,000  people.  Other  communities  in  the 
immediate vicinity of the project include Hacienda Nueva (3 km west), Morelos (5 km northwest) and Veta Grande 
(5  km  north).  The  Cozamin  Mine  operates  year-round  and  is  accessible  via  paved  roads  to  the  project  area 
boundary where good, all-weather roads provide access to the mine and most of the surrounding area. The mine 
area falls within the Hacienda Nueva and La Pimienta Ejidos. 

The Cozamin Mine has excellent surrounding infrastructure including schools, hospitals, railroads, highways, and 
electrical power. The mine has access to a power line and substation that allows Capstone to draw up to 7.5 MW 
from the national power grid. Cozamin has requested an increase to 9.5 MW and is awaiting approval from El 
Centro  Nacional  de  Control  de  Energía  (“CENACE”).  Generators  (both  operating  and  back-up)  on  site  have  a 
capacity of 1.0 MW. There is sufficient capacity to store all of the tailings from the processing of identified Mineral 
Reserves,  assuming  continued  proper  tailings  management  and  construction  of  the  permitted  upstream  raise. 
Employees and contractors are sourced from Zacatecas and other nearby communities with minimal foreign staff 
at the mine. Sufficient surface rights have been obtained to conduct all mining operations. 

The climate in the region is semi-arid with maximum temperatures of approximately 30°C during the summer and 
minimum temperatures in the winter producing freezing conditions and occasional snow. The rainy season extends 
from June until September, with average annual precipitation totalling approximately 500 mm. As the certainty of 
runoff into the tailings pond cannot be predicted, additional water resources have been secured, with further water 
rights undergoing evaluation. 

26 

 
 
The Cozamin Mine is located in the Western Sierra Madre Physiographic Province near the boundary with the 
Mesa Central Province (Central Plateau Province). The Zacatecas area is characterized by rounded northwest 
trending mountains with the Sierra Veta Grande to the north and the Sierra de Zacatecas to the south. Elevations 
on the property vary from 2,400 m to 2,600 masl. The Zacatecas area is located between forested and sub-tropical 
regions to the southwest and desert conditions to the northeast. Vegetation consists of natural grasses, mesquite 
or huizache and crasicaule bushes. Standing bodies of water are dammed as most streams are intermittent. 

History 

In pre-Hispanic times, the area was inhabited by Huichol people who mined native silver from the oxidized zone 
of  argentiferous  vein  deposits  in  the  Zacatecas  Mining  District.  During  the  Spanish  Colonial  era  production 
commenced in 1548 at 3 mines: the Albarrada mine on the Veta Grande system, and the San Bernabe mine and 
Los Tajos del Panuco on the Mala Noche Vein system. The initial operations worked only the oxide minerals for 
silver and some gold, and later the sulphide-mineral zones were worked for base and precious metals. 

From  1972,  Consejo  de  Recursos  Minerales  worked  mines  in  El  Bote,  La  Purisima  and  La  Valencia  zones.  A 
number of old workings are located throughout the mine area, but accurate records of early production are not 
available. Consejo de Recursos Minerales estimated Zacatecas district historic production until 1992 at 750 million 
ounces  of  silver  from  20  million  tonnes  grading  over  900  g/t  Ag  and  approximately  2.5  g/t  Au.  Lead,  zinc  and 
copper have also been recovered but the production and grades were not estimated. 

Minera Cozamin was established in 1982 by Jack Zaniewicki who consolidated concession holdings over much of 
the Mala Noche Vein and operated the San Roberto Mine and plant at 250 tpd until October 1996. During this 
period,  Industrias  Peñoles  S.A.  de  C.V.  (“Peñoles”)  undertook  exploration  in  the  district  but  did  not  buy  any 
significant  concessions.  In  all,  it  is  estimated  that  1.2  million  tonnes  of  ore  were  mined  and  processed  at  the 
Cozamin Mine prior to October 1996. 

In October 1996, Zaniewicki sold Cozamin to Minera Argenta, a subsidiary of Minera Bacis S.A. de C.V. (“Bacis”). 
Bacis expanded the mill to a 750 tpd flotation plant, and processed 250,000 tonnes of ore grading 1.2% Cu, 90 g/t 
Ag, 0.5 g/t Au, 1.8% Zn and 0.6% Pb from 1997 to the end of 1999, mainly from shallow, oxide zone workings. 
Bacis developed resources principally by drifting and raising on the Mala Noche Vein within the San Roberto zone. 
Diamond  drilling  was  only  used  as  an  exploration  tool  to  identify  areas  with  mineralization  peripheral  to  the 
developed mine workings. In 1999, Bacis closed the mine primarily due to low metal prices and under-capitalization 
of the asset. Capstone  assumed ownership of the Cozamin Mine in 2004. 

Geological Setting 

The Zacatecas Mining District covers a belt of epithermal and mesothermal vein deposits that contain silver, gold 
and base metals (copper, lead and zinc). The district is in the Southern Sierra Madre Occidental Physiographic 
Province near the boundary with the Mesa Central Physiographic Province in north-central Mexico. The dominant 
structural  features  that  localize  mineralization  are  of  Tertiary  Era  age  and  are  interpreted  to  be  related  to  the 
development of a volcanic centre and to northerly trending basin-and-range structures. It occurs in a structurally 
complex setting, associated with siliceous subvolcanic and volcanic rocks underlain by sedimentary and meta-
sedimentary  rocks.  The  geologic  units  in  this  area  include  Triassic-aged  metamorphic  rocks  of  the  Zacatecas 
Formation  and  overlying  basic  volcanic  rocks  of  the  Upper  Jurassic-aged  or  Lower  Cretaceous-aged  Chilitos 
Formation. The Tertiary rocks consists mainly of a red conglomerate unit deposited in the Paleocene Epoch and/or 
Eocene Epoch and overlying rhyolitic tuff and intercalated flows that were deposited from Eocene to Oligocene 
Epochs. Some Tertiary Era rhyolite bodies cut the Mesozoic Era and Tertiary Era units and have the appearance 
of flow domes. 

The host rocks for the MNV are intercalated carbonaceous meta-sedimentary rocks and andesitic volcanic rocks 
ranging in age from Triassic to Cretaceous, and Tertiary-aged rhyolite intrusive rocks and flows. Mineralization in 
the  MNV  appears  to  have  been  episodic.  A  copper-silver  dominant  phase  is  interpreted  as  the  first  stage  of 
mineralization and is considered to  be the most important phase of mineralization at Cozamin. In general, this 

27 

 
copper-silver phase was emplaced then enveloped, overprinted or brecciated by moderate to strong zinc-lead-
silver mineralization. Local rheology contrasts between rock units may have some control on vein emplacement, 
as well as metal content. 

Exploration 

Cozamin  exploration geologists have systematically  mapped a total of 1,694 ha throughout the Cozamin  Mine 
property at scales of 1:1000 or 1:2000 since 2004. Regular surface exploration along the strike of the MNV system 
has occurred through channel sampling and chip sampling. Channel samples were cut perpendicular to the strike 
of the vein and weighed approximately 2 kg. The results of the surface channel and chip sampling programs have 
been used to assist with exploration drillhole planning, but not used for Mineral Resources estimation. In 2015, 
150 hectares were remapped at a scale of 1:2000 predominantly in the San Rafael area. 

Capstone undertook several geophysical surveys using contractors between 2004 and 2010. A ground magnetic 
survey completed by Zonge Engineering and Research Organization (“Zonge”) in 2004 collected total magnetic 
field data from 24 north-oriented lines spaced 25 m apart that permitted mapping of the linear east-west orientation 
of the Mala Noche system as well as other intrusive features. Also in 2004, Zonge undertook a resistivity study 
through  measurement  of  magnetic  response  using  Controlled  Source  Audio  Magnetotellurics  over  8  line-
kilometres and Natural Source Audio Magnetotellurics over 16 line-kilometres indicated the presence of sulphide 
mineralization  below  known  mineralized  extents.  These  results  were  used  to  assist  with  exploration  drillhole 
planning. During the summer of 2009, New Sense Geophysics Limited conducted an aeromagnetic survey over 
all of the Cozamin Mine concessions. The results revealed a broad magnetic high trending northwest. These data 
were later reprocessed in 2013 and used for tracking infrastructure such as power lines and pipe lines and the 
general structural and vein trends of the Mala Noche system. In some cases, the data were used as a secondary 
tool to help guide exploration and drill planning in new target areas. Between October 2009 and January 2010 
Zonge completed resistivity and ground-induced polarization studies centered over Mala Noche West, Hacienda 
Nueva South, Mala Noche North, and Mala Noche East. Identified anomalies were followed up by drilling, but the 
results were poor. The presence of sulphide-rich and graphitic sedimentary rocks coupled with close proximity to 
populated  areas  (buried  pipes,  fences,  etc.),  likely  precluded  effective  chargeability,  resistivity,  or  conductivity 
surveys, and as such we have not explored using geophysical methods since 2010. In 2015, Condor Consulting 
Ltd.  conducted  a  full  review  of  all  previous  geophysical  surveys  and  determined  the  most  likely  effective 
geophysical survey method for future exploration targeting is total field magnetics and derivative products. 

Mineralization 

All  mineralization  at  the  Cozamin  mine  occurs  in  veins  and  stockworks  of  veinlets.  On  surface,  the  MNV  was 
mapped for 5.5 km across the property. It strikes approximately east-west and dips on average at 60° to the north. 
Several shafts provided access to historical workings at Cozamin. The largest mined area is the San Roberto zone 
with a strike length of 1.4 km and a vertical extent of 820m. Adjacent to the San Roberto zone is the San Rafael 
zone,  a  zinc-rich  part  of  the  deposit  with  the  same  mineralization  characteristics  as  the  San  Roberto  zone. 
Mineralization peripheral to the historical workings was the principal target of Capstone’s exploration at Cozamin. 
The MNFWZ, a splay off the footwall (south) side of MNV discovered in 2010, is not exposed at surface. Based 
on underground drilling, MNFWZ strikes ~145° over more than 2.5 km and dips on average 54° to the northeast. 
Known base metal mineralization at MNFWZ has a maximum vertical extent of approximately 800m. The MNFWZ 
comprises  multiple  veins  in  close  spatial  association  with  rhyolite  dikes  and  locally  cross-cut  the  intrusions 
themselves. The relative age of the copper mineralization ranges from contemporaneous with to perhaps slightly 
post the rhyolite magmatism. 

The MNV system occupies a system of anastomosing faults. The mineralized bodies within the Mala Noche Fault 
System appear to be strongest where the individual faults coalesce into a single fault zone. 

Currently  mined  mineralization  at  Cozamin  is  best  described  as  intermediate  sulphidation.  The  copper-rich 
intermediate sulphidation mineralization is an early phase that is enveloped, overprinted or brecciated by zinc-rich 
intermediate sulphidation mineralization. The copper veins are inferred to be higher temperature, have significantly 

28 

 
fewer vugs and can be massive pyrrhotite-pyrite-chalcopyrite with little gangue. Zinc-rich veins also tend to  be 
sulphide rich, like the copper-rich ones, but with slightly more gangue. Well-banded quartz, or quartz-carbonate 
veins are inferred to be lower temperature and best classified as low sulphidation. They often have open space 
filling textures with quartz druse vug linings, are typically less sulphide rich and are gold and silver rich with lesser 
base metals and are generally not being mined on the property, but were historically important. 

This transition from intermediate sulphidation copper-dominant mineralization to intermediate sulphidation zinc-
dominant  mineralization  is  thought  to  be  the  result  of  an  evolving,  telescoped  hydrothermal  system.  Blocks  or 
fragments of massive chalcopyrite-pyrite-pyrrhotite mineralization enveloped by zinc-dominant mineralization are 
observed in drill core and in mine workings. This telescoping system is closely associated with the district’s largest 
center of rhyolite flow domes which may be the shallow expression of a hidden, inferred buried felsic stock. 

Pyrite is the dominant vein sulphide, is highly variable in concentration but typically comprises approximately 15% 
of the MNV in the San Roberto zone. Pyrrhotite commonly occurs as an envelope to, or intermixed with, strong 
chalcopyrite  mineralization.  Chalcopyrite  is  the  only  copper  sulphide  recognized  visually  at  the  Cozamin  mine. 
Like  pyrrhotite,  it  is more common  at  intermediate  and deeper levels  of the  mine. It occurs as disseminations, 
veinlets  and  replacement  masses.  Mineralization  at  the  MNFWZ  is  chalcopyrite  dominant  in  contrast  to  the 
polymetallic  nature  of  the  MNV.  Sphalerite  is  the  dominant  economic  sulphide  in  the  upper  levels  in  the  San 
Roberto mine. Most of the sphalerite is marmatitic. It occurs as disseminations and coarse crystalline masses and 
is commonly marginal to the chalcopyrite-dominant portion of the vein. Argentiferous (silver-bearing) galena is less 
common  than  sphalerite  but  is  generally  associated  with  it  as  crystalline  replacement  masses.  Arsenopyrite 
typically occurs as minor, microscopic inclusions in pyrite. Argentite is the most common silver mineral. It has been 
identified microscopically occurring as inclusions in chalcopyrite and pyrite. Gangue minerals  in the intermediate 
sulphidation veins consist of quartz, silica, calcite, chlorite, epidote and minor disseminated sericite. The quartz 
occurs as coarse-grained druse crystalline masses, and a stockwork of quartz veinlets. 

Drilling 

In all, 1,103 diamond drillholes including 956 holes of HQ and/or NQ diameter and 147 holes of BQ diameter have 
been completed from surface and from underground locations at the Cozamin Mine since April 2004. A total of 17 
phases of drilling have targeted resource definition and expansion along the MNV (San Roberto and San Rafael 
zones), MNFWZ (since discovery in 2010), and other exploration targets on our property.  

In 2019, Capstone drilled a total of 56,572 m in 87 angled HQ diamond drillholes and 6,755 m in 52 angled BQ 
diamond drillholes at the MNFWZ, plus 2,358 m in 3 angled HQ diamond drillholes at other brownfield targets on 
our property. Drilling for 2018 totaled 75,988 m in 108 angled HQ diamond drillholes and 1,926m in 15 angled BQ 
diamond  drillholes  at  the  MNFWZ,  plus  1,268  m  in  11  holes  in  the  San  Rafael  zone  of  MNV  to  define  ore 
boundaries immediately before mining. In 2017, Capstone drilled a total of 32,662 m in 44 angled, HQ diameter, 
diamond drillholes  at the  MNFWZ, 10,215 m in 28  angled,  HQ diameter, diamond drillholes  at the San Rafael 
zone, 1,945 m in 16 angled, HQ diameter, diamond drillholes at the San Roberto Zinc zone, and 2,019 m in 3 
angled, HQ diameter, diamond drillholes at a new brownfield target located east of San Rafael. Drillhole collars 
are located using a total station TRIMBLE instrument, model S6. Downhole survey readings were recorded using 
either an Eastman Single Shot, FLEXIT SensIT or Reflex EZShot instrument. Survey readings are generally taken 
every 50-150 m for surface holes and every 50-100 m for underground holes. Survey results were corrected for 
magnetic declination. 

In  the  core  logging  facility,  drillholes  are  assessed  for  drilling  recovery,  which  has  historically  been  very  good. 
Drillholes are then logged for geology, alteration and mineralogy, followed by structural data measurements and 
rock quality (RQD) assessment. Next, the drillholes are marked for sampling by the geologist. This is followed by 
core photography before the core is sent for cutting. 

29 

 
 
 
Sampling and Analysis 

We use diamond drillcore samples for Mineral Resources estimates. Diamond drillholes intersecting the MNV are 
spaced approximately 60 m along strike and down dip in the San Roberto zone. In 2017, infill drilling closed the 
drillhole spacing to approximately 40 m in the San Rafael zone. Mineralization is less continuous in the MNFWZ 
than in the MNV, thus drillholes are more closely spaced averaging approximately 45 m along strike and down 
dip. The entire vein width is sampled. Typical sample intervals for drillcore are 0.5 m in the vein and 2 m in the 
wallrock  (waste).  Very  high-grade  intervals  are  marked  out  and  sampled  separately  from  lower  grade  zones. 
Sample boundaries are based on mineral proportions and/or texture (e.g. massive versus disseminated). Drillcore 
samples  are  split  by  core  saw  and  placed  in  marked  bags  and  shipped  to  accredited  external  laboratories  for 
sample preparation and analysis for copper, lead, zinc, silver, and sometimes gold. Samples from BQ diameter 
are whole core. There were a total of 63,969 diamond drillhole samples contained in the database used for the 
October  2018  Mineral  Resources  update  of  the  MNFWZ  and  MNV  block  model.  Capstone  employees  are 
responsible for all on-site sampling of drill core. 

Sample quality of drillhole samples is monitored through regular insertion of reference material standards, blanks, 
and duplicate samples. Certified reference material standards are purchased commercially and are also created 
from MNV material. QAQC procedures include real-time monitoring of quality control data, thresholds for sample 
failures  and  sample  batch  reanalysis,  and  regular  monthly  reporting.  QAQC  results  demonstrate  that  drillhole 
assay  values  are  accurate  and  repeatable.  In  2018,  the  cross  contamination  first  observed  in  2017  across  all 
elements,  particularly  zinc,  was  intermittent.  The  impact  of  these  blank  failures  on  ore-waste  classification  is 
considered low. Investigation into the root cause and mitigation continues. 

The  Cozamin  Mine  collects  bulk  density  measurements  from  mineralized  and  non-mineralized  intercepts  from 
each drillhole. All drillcore pieces greater than 10 cm in length within an assay sample length are selected from 
the core box and measured using a weight-in-air weight-in-water technique. A review of these data highlighted 
widely ranging values, which were reanalyzed as a part of a quality control check. The QAQC samples indicated 
the bulk density dataset was of sufficient quality for use in Mineral Resource estimation. There are 37,428 bulk 
density measurements in the database available to estimate density. 

Database validation work comprises a check of 10% of all new records entered into the database as a part of the 
Mineral Resource update process. This includes verification of collar, downhole survey, lithology, assay, and bulk 
density data. This was completed twice in 2018 as part of the Mineral Resource update process. Other data checks 
included validations of the spatial locations of mineralized drillhole intercepts and the locations of production chip-
channel sample data with respect to underground mapped geology. Errors were noted and corrected. There were 
27 drillholes excluded from the geological modelling and Mineral Resource estimation process because either the 
logged  vein  intercepts  fell  outside  of  modelled  vein  structures,  the  hole  twinned  another  intersection,  or  they 
intercepted the vein at a very shallow angle.  

Security of Samples 

Only employees of Capstone entities are permitted in the core shack when unsampled drillcore is ready to be cut. 
Approximately 10 samples are placed in a large sack and secured by a tamper proof seal. A transmittal form is 
then completed, which identifies the batch number, the serial numbers of the seals and the corresponding sample 
number series, and delivered to the sample preparation laboratory by a Cozamin representative. 

Drill core containing intercepts of the MNV and MNFWZ structure is stored in a secured warehouse near the core 
shack. Waste hanging wall and footwall drill core is kept in a secure storage facility on the property and within the 
mine on Level 8. Access to the warehouse and storage facilities are controlled by the Mine Geology Department. 
No person other than the geologists responsible for logging is permitted to handle the core prior to sampling.

Mineral Resource and Mineral Reserve Estimates 

In March and October 2018, the MNFWZ block model was updated to incorporate drilling at MNFWZ. The July 
2017 MNV block model was updated to reflect the revised NSR formula and new cut-off NSR used in the updated 
MNFWZ model. Garth  Kirkham, P.Geo., FGC,  Kirkham Geosystems Ltd.,  an  independent Qualified Person as 
defined by NI 43-101, is responsible for the Cozamin Mineral Resource estimates. 

The NSR formula used to report Mineral Resources at MNV and MNFWZ is based on projected long-term metal 
prices of $3.50/lb copper, $18.00/oz silver, $1.20/lb zinc, and $1.00/lb lead with metal recoveries of 95% Cu, 78% 
Ag, 58% Zn, 40% Pb. Mineral Resources are reported at a cut-off of NSR $50.  

All  geological  modelling  was  undertaken  using  the  Leapfrog®  Geo  implicit  modelling  software.  It  comprised  a 
lithological model to assist with exploration targeting and mining planning activities, as well as a mineralization 
model  defining  the  mineralized  MNV  and  MNFWZ  structures.  The  veins  were  defined  using  logged  and 
underground-mapped contacts in combination with high NSR values as a guide where mineralization boundaries 
were not exclusively defined in a vein structure.  

All  MNV  samples  were  composited  to  a  2 m  length  and  MNFWZ  samples  were  composited  to  1  m.  This  was 
followed by an exploratory data analysis that showed a moderate correlation between copper and silver in the San 
Roberto zone, San Rafael zone, and MNFWZ. In the San Rafael zone, zinc and lead also showed a moderate 
correlation. The coefficient of variation (“COV”), which measures the spread of a distribution relative to its mean, 
was reviewed for each element to help assess the need for top cutting and to confirm the selected OK estimation 
method was appropriate. A COV of less than 1.5 is desired for OK grade estimation, which was found for copper, 
silver, and zinc. Minor top cuts were needed for these elements. Lead had a COV higher than 2 resulting from a 
longer high-grade tail of samples. This aligns with underground observations where lead can be found in high-
grade patches. As such, a combination of top cutting and search restrictions were used to limit the influence of the 
high-grade lead samples. In MNFWZ, both lead and zinc had COV over 2, indicating higher variability. The impact 
of  high-grade  lead  and  zinc  samples  at  MNFWZ  was  limited  using  top-cutting.  The  modelled  mineralization 
triangulations were treated as hard boundaries at MNV and MNFWZ. 

The three-dimensional spatial relationships of each element were assessed on the top-cut, composited data was 
undertaken  using  normal-score  transformed  semi-variograms.  At  MNV,  search  ellipses  were  set  to  vary 
dynamically during grade estimation to account for the local variations in strike and dip along the veins. The same 
variogram  and  search  parameters  were  used  for  copper  and  silver  in  all  domains  to  maintain  the  element 
correlations. At MNFWZ, the search ellipses were set as 100m spheres. At both MNV and MNFWZ, estimates do 
not cross the modelled mineralization triangulations. 

Grades were estimated into 12 m Easting × 2 m Northing × 10 m Elevation blocks in a sub-blocked model (in the 
MNFWZ  model the blocks  were rotated parallel to the strike of the mineralization). Bulk density samples were 
composited to 1.0 m lengths downhole and estimated using inverse distance weighting. Model validation included 
visual validation of grades against composited drillhole samples, creation of swath plots along easting, northing 
and elevation sections to assess grade smoothing, assessment of element correlations in the blocks, as well as a 
global  change  of  support  to  assess  grade  smoothing  at  various  cut-off  grades.  Validation  checks  showed  the 
model to be valid with an appropriate amount of grade smoothing.  

The June 2016 MNV and MNFWZ Mineral Resource models were externally reviewed by SRK Consulting. No 
material issues were identified with the geological modelling, estimation, validation, or classification process. The 
July 2017 MNV update followed the same methodology employed in the 2016 estimates.  

At MNV, grades were re-estimated in March 2018 and October 2018 using revised NSR formulae that included 
updated metallurgical recoveries and long-term outlook metal prices and updated NSR cut-offs of $42 and $50, 
respectively. In July 2017, the San Roberto zone geological interpretation was modified slightly, a zinc zone was 
broken out and grades were re-estimated. Zinc-oxide mineralization was identified in this zone during metallurgical 
test work and is estimated to represent on average 18% of the total zinc mineralization in the San Roberto zinc 

31 

 
zone.  However,  the  highest  concentrations  of  zinc-oxide  mineralization  are  not  spatially  associated  with  the 
highest zinc grades. Additional metallurgical studies are on-going to determine whether this zone is economically 
viable. In the San Rafael zinc zone, zinc-oxide mineralization is  not  observed. The NSR formula used for zinc 
zones is the same formula used for copper zones, and used recoveries of 95% copper, 78% silver, 58% zinc, and 
40% lead, and long-term estimated metal prices of $3.50/lb copper, $18.00/oz silver, $1.20/lb zinc, and $1.00/lb 
lead. NSR formulae are based on the blended ore stream received by the mill. 

The  updated  Measured  and  Indicated  Mineral  Resources  for  the  MNV  and  MNFWZ  copper  zones,  after  2019 
mining activities, total 14,091 kt with an average grade of 1.63% Cu above a $50 per tonne NSR cut-off (Table 3). 
The  NSR  formula  is  stated  in  the  table  notes.  Garth  Kirkham,  P.Geo.,  FGC,  Kirkham  Geosystems  Ltd.,  an 
independent  Qualified  Person  as  defined  by  NI  43-101,  is  responsible  for  the  Mineral  Resource  estimates  at 
Cozamin.  Mineral  Resources  are  presented  inclusive  of  Mineral  Reserves.  Mineral  Resources  are  not  Mineral 
Reserves and do not have demonstrated economic viability.

NOTE: The Cozamin Mineral Resource estimate was completed by Garth Kirkham, P.Geo., FGC, Kirkham Geosystems 
Ltd.,  and  an independent  Qualified  Person as  defined by  NI  43-101.  The  NSR  formula  used is  based  on  $3.50/lb  Cu, 
$18/oz Ag, $1.20/lb Zn, $1.00/lb Pb and metallurgical recoveries of 95% Cu, 78% Ag, 58% Zn, 40% Pb. The resulting 
NSR formula is Cu*65.024 + Ag*0.438 + Zn*10.755 + Pb*6.981. Mineral Resources are reported above $50/t NSR cut-
off. Mineral Resources are presented inclusive of Mineral Reserves. Mineral Resources are not Mineral Reserves and do 
not have demonstrated economic viability. Figures may not sum due to rounding. Contained metals are reported at 100%. 

33 

 
The MNV and MNFWZ Mineral Reserve model was updated in October 2018, by Tucker Jensen, P.Eng., Senior 
Mining Engineer at Capstone and a Qualified Person as defined by NI 43-101, using the October 2018 Mineral 
Resource models updated by Garth Kirkham, P.Geo., FGC. The Mineral Reserve estimate was generated using 
base assumptions of $2.75/lb copper, $16.00/oz Ag, $1.10/lb Zn, by longitudinal longhole open-stoping mining. 
The  cut-off  value  used  was  $50.00.  Development  and  stope  triangulations  were  generated  in  Maptek  Stope 
Optimizer software (“MSO”). These triangulations were applied to the MNV and MNFWZ Mineral Resource block 
models  after  the  models  were  depleted  of  past  mining  production  and  areas  of  geotechnical  sterilization.  The 
Mineral Reserve estimate also factors in unrecoverable geotechnical support pillars, 5% production losses and 
dilution. Mining widths of 2.0 to 9.0m were applied. Mineral Reserves were classified as Proven and Probable in 
accordance with CIM Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014). 

A geotechnical study was completed 2017-2018 to improve confidence in the mining methodology and to consider 
the appropriateness or make modifications to the  ground support methods continued in 2019. Further study on 
pillar recovery optimization is ongoing with an updated assessment to be completed  in 2020. Dilution and mining 
recovery  factors  need  to  be  continuously  validated  through  annual  reconciliations  and  adjusted  as  required, 
especially in lithologies where historical mining experience is low.  

Proven and Probable Mineral Reserves, discounted for mine production to December 31, 2019, contain 5,166 kt 
at an average grade of 1.50% Cu above a $50/t NSR cut-off (fully diluted and recovered) are detailed in the table 
below. Tucker Jensen, P.Eng., Senior Mining Engineer at Capstone and a Qualified Person as defined by NI 43-
101, is responsible for the Mineral Reserve estimates at Cozamin.

NOTE: Tucker Jensen, P.Eng., Senior Mining Engineer at  Capstone  Mining  Corp.,  is  the  Qualified  Person  for  the  Cozamin 
Mineral Reserve. Disclosure of the Cozamin Mine Mineral Reserves as of December 31, 2019 was completed using fully 
diluted mineable stope shapes generated by the Maptek Vulcan Mine Stope Optimizer software and estimated using the 
2018 MNFW and MNV resource block models completed by Garth Kirkham, P.Geo., FGC, Kirkham Geosystems Ltd. The 
Reserves are based on a $50/t NSR cut-off. The NSR formula used for the Reserves was based $2.75/lb Cu, $16/oz Ag, 
$1.10/lb Zn, and metallurgical recoveries of 96.5% Cu, 81% Ag, 44% Zn. The resulting NSR275 formula is ($50.707*%Cu 
+  0.366*Ag  ppm  +  7.276*Zn%)*(1-NSRRoyalty%).  Note  that  zero  value  is  attributed  to  Pb  due  to  low  concentrations. 
Tonnage and grade estimates include dilution and recovery allowances. The NSR royalty rate applied varies between 1% 
and  3%  depending  on  the  mining  concession.  Contained  metals  are  reported  as  100%.  Figures  may  not  sum  due  to 
rounding.

Mining Operations 

The Cozamin Mine is an underground mining operation that commenced in 2006. Ore is extracted primarily using 
long-hole open stoping. The mine extends for a strike length of over 2 km and Mineral Reserves extend to a depth 
of 1,000 m. Access to the underground workings is via two service and haulage ramps and a hoisting shaft. 

Run-of-mine ore is stockpiled on surface and sent to the crushing plant. The crushed ore is stored in two ore bins 
that feed parallel conventional grinding circuits. The resulting product is sent to the copper-lead rougher flotation 
where a copper- lead concentrate is produced. The tailings report to zinc conditioning tanks prior to zinc flotation, 
where reagents are added to activate zinc mineralization. The tailings go through zinc rougher and cleaning circuits 
to  product  a  zinc  concentrate.  Separate  copper  and  lead  concentrates  are  produced  from  the  copper-lead 
concentrate  via  selective  flotation.  The  concentrates  are  thickened  and  filtered  to  produce  product  suitable  for 
transport.  The  concentrates  are  trucked  to  Manzanillo,  Colima,  Mexico.  The  current  mine  plans  maintain  the 
Cozamin Mine operations life to 2024.  

A 2018 internal material handling study concluded the current hoisting and haulage resources were limiting mine 
production,  and  that  the  under-utilized  plant  is  capable  of  an  additional  842  tpd.  A  traffic  study  identified  truck 
haulage capacity is reduced by about 35% because of the bi-directional use of one of Cozamin’s two ramps for 
ore haulage. A one-way truck haulage loop will be created by connecting the two current ramps with ~1,600m of 
ramp development at -1:7 gradient. The one-way haulage loop is on schedule for completion before the end of 
2020. 

Permits required to conduct on-going mining work on the property have been obtained; permits required for the  
targeted production increase are under consideration. There are no known factors or risks that affect access, title 
or the ability to conduct mining. Environmental liabilities and issues are limited to those that are expected to be 
associated  with  an  underground  base  metal  operation.  These  include  an  underground  mine,  associated 
infrastructure,  access  roads  and  surface  infrastructure  including  the  process  plant,  waste  and  tailings  disposal 
facilities situation within the area of disturbance. 

The Cozamin Mine’s applicable taxes include the following: 

•  Corporate  Taxes  -  the  Mexican  corporate  income  tax  is  at  a  30%  rate  applied  on  net  income  after 

depreciation.  

•  A value added tax is payable to the Mexican government. Any overpaid (credit) amount may be offset with 

receivable value added tax. . 

•  The 2013 Mexican Tax Reform introduced a 7.5% mining tax. The mining tax, effective January 1, 2014, is 
applied on the positive difference between income arising from sales related to mining and the deductions 
permitted by the Income Tax Law, not including deductions on investments (except those involved in mining 
prospecting and exploration), interest payable and the annual inflation adjustment. The Tax Reform also 
introduced a 0.5% mining tax on precious metals that is applied on gross taxable revenues. 

•  Property taxes are approximately $20,000 per year. 
•  The  State  of  Zacatecas  introduced  taxes  effective  January  1,  2017  for  purposes  of  reducing  the 
environmental impact created by industrial activities carried out in the state. These new taxes consist of the 
(i)  Environmental  Remediation  Tax  on  the  Extraction  of  Materials,  (ii)  Tax  on  Gas  Emissions  to  the 
Atmosphere, (iii) Tax on Emissions of Pollutants to the Soil, Subsoil, and Water, and (iv) Tax on the Disposal 
of Wastes. Taxes are calculated based on a rate per tonne of gas emitted, waste deposited, and per meters 
of soil contaminated. The total environmental taxes paid by Cozamin were approximately $37,000 in 2019, 
$38,000 in 2018 and $165,200 in 2017.  

Exploration and Development 

The  2020  exploration  program  includes  a  proposed  43,000  metres  of  infill  drilling  at  MNFWZ  and  step-out 
exploration drilling to test for further extensions on the MNFWZ and additional structures splaying from the main 
Mala Noche fault system.

Other Properties 

Santo Domingo Project (Chile) 

The Santo Domingo copper-iron-gold project (“Santo Domingo” or “the Project”) is a fully-permitted development 
project located in Region III, Chile, and is owned 70% by Capstone and 30% by Korea Resources Corporation 
(“KORES”). The Project has all required construction permits and received final approval of the Mine Closure Plan 
in 2019. 

In 2019, Capstone updated the economic model for the Project with more certain cost estimates, and studied the 
option to produce battery-grade cobalt sulphate. In March 2020 Capstone published an updated technical report 
for  the  Project  titled  “Santo  Domingo  Project,  Region  III,  Chile,  NI  43-101  Technical  Report”  (“2020  Santo 
Domingo  Technical  Report“)  effective  February  19,  2020.  The  2020  Santo  Domingo  Technical  Report  was 
authored by Joyce Maycock, P.Eng., Amec Foster Wheeler Ingeniería y Construcción Ltda (doing business as 
Wood) (“Wood”), Antonio Luraschi, CMC, Wood, Marcial Mendoza, CMC, Wood, Mario Bianchin, P.Geo., Wood 
Canada  Ltd.,  David  Rennie,  P.Eng.,  Roscoe  Postle  Associates  Inc.  (“RPA”),  Carlos  Guzman,  CMC,  NCL 
Ingeniería y Construcción SpA (“NCL”), Roger Amelunxen, P. Eng., Aminpro, Michael Gingles, QP MMSA, Sunrise 
Americas LLC, Tom Kerr, P.Eng., Knight Piésold Ltd., Roy Betinol, P.Eng., BRASS Chile SA, Lyn Jones, P.Eng., 
M.Plan International, each an independent Qualified Person as defined in NI 43-101, and Gregg Bush, P.Eng., 
non-independent  consulting  engineer.  The  following  descriptions  of  the  Santo  Domingo  Project  are  based  on 
assumptions, qualifications and procedures which are set out in the 2020 Santo Domingo Technical Report filed 
on March 24, 2020. Reference should be made to the full text of this report which is available in its entirety on 
SEDAR at www.sedar.com under Capstone’s profile. 

Capstone has two groups of concessions with a total of 116 claims (96 exploitation concessions totaling 27,597 
ha and 20 exploration concessions totaling 1,300 ha) that cover a total of 28,897 ha and include the areas of the 
planned mine site, plant area, and auxiliary facilities including proposed port facilities. Easements to cover 100% 
of the facilities and infrastructure area  are in progress. Current surface rights include  17 registered  provisional 
surface rights (3,634 ha) and 16 definitive surface rights (3,856.78 ha); applications for an additional six definitive 
surface rights (239.84 ha) are in progress. 

The centre of the Project is located at approximately 26°28'00”S and 70°00'30”W. Most areas of the proposed 
open  pits  are  located  on  concessions  subject  to  one  or  the  other  of  two  2%  NSR  agreements  with  BHP  and 
Empresa Nacional de Mineria, commonly called ENAMI, a Chilean government corporation. On June 17, 2011, 
Capstone entered into a strategic relationship with KORES. The terms of this relationship provided for, amongst 
other things, a private placement in the equity of Capstone, representation on the Board of Directors of Capstone, 
the acquisition of a 30% interest in the project by KORES, participation in the financing of the project as well as 
an agreement to enter into a life of mine off-take agreement for 50% of the production of copper and iron from the 
project on prevailing market terms. 

The  currently  proposed  project  uses  desalinated  water  and  will  not  require  an  application  for  water  rights.  An 
approved maritime concession will allow the extraction of sea water for processing in the desalination plant. Water 
for construction will be obtained from an authorized third-party provider. 

Mineral Resource and Mineral Reserve Estimates 

David  Rennie,  P.Eng.,  of  RPA,  is  the  Qualified  Person  responsible  for  the  preparation  of  the  Santo  Domingo 
Mineral Resources estimates presented in the 2020 Santo Domingo Technical Report. The Mineral Resources 
estimates for Santo Domingo Sur, Iris, Iris Norte and Estrellita are presented in Table 5 and have an effective date 
of February 13, 2020. 

Risk factors that could potentially affect these Mineral Resources estimates include changes to assumed long-
term metal prices and exchange rates, densities, geotechnical and hydrogeological considerations, factors used 
in  the  preliminary  pit  optimization  on  the  block  models  using  a  Lerchs–Grossmann  algorithm  (“LG  shell”)

NOTE: Mineral Resources are classified according to CIM (2014) standards. Mineral Resources are reported inclusive of 
Mineral  Reserves.  Mineral  Resources  that  are  not  Mineral  Reserves  do  not  have  demonstrated  economic  viability.  The 
Qualified  Person  for  the  estimates  is  Mr.  David  Rennie,  P.  Eng.,  an  associate  of  Roscoe  Postle  Associates  Inc.  Mineral 
Resources for the Santo Domingo Sur, Iris, Iris Norte and Estrellita deposits have an effective date of 13 February 2020.  
Mineral Resources for the Santo Domingo Sur, Iris, Iris Norte and Estrellita deposits are reported using a cut-off grade of 
0.125%  copper  equivalent  (CuEq).  CuEq  grades  are  calculated  using  average  long-term  prices  of  US$3.50/lb)  Cu, 
US$1,300/oz Au and US$99/(dmt) Fe conc. The CuEq equation is: % Cu Equivalent = (Cu Metal Value + Au Metal Value + 
Fe Metal Value) / (Cu Metal Value per percent Cu). The general equation for metal value is: Metal Value = Grade * Cm * R * 
(Price – TCRC – Freight) * (100 – Royalty) / 100, were Cm is a constant to convert the grade of metal to metal price units, R 
is metallurgical recovery, and TCRC is smelter treatment charges and penalties. Only copper, gold and iron were recognized 
in  the  CuEq  calculation;  cobalt  and  sulphur  were  excluded.  Mineral  Resources  are  constrained  by  preliminary  pit  shells 
derived  using  a  Lerchs–Grossmann  algorithm  and  the  following  assumptions:  pit  slopes  averaging  45º;  mining  cost  of 
US$1.90/t,  processing  cost  of  US$7.27/t  (including  G&A  cost);  processing  recovery  of  89%  copper  and  79%  gold,  iron 
recoveries  are  calculated  based  on  magnetic  susceptibility;  and  metal  prices  of  US$3.50/lb  Cu,  US$1,300/oz  Au  and 
US$99/dmt  Fe  concentrate.  Rounding  as  required  by  reporting  standards  may  result  in  apparent  summation  differences.  
Tonnage measurements are in metric units. Copper, iron and sulphur are reported as percentages, gold as grams per tonne 
and cobalt as parts per million. 

Mr. Carlos Guzman, CMC, an employee of NCL, is the Qualified Person responsible for the preparation of the 
Santo Domingo Mineral Reserves estimate presented in the 2020 Santo Domingo Technical Report. The effective 
date of the Mineral Reserves estimate is November 14, 2018. 

Pit optimization, mine design and mine planning were carried out by NCL using the 2012 block model prepared 
by  RPA  and  did  not  include  consideration  of  material  classified  as  Inferred.  Inferred  Mineral  Resources  were 
treated as waste. A block size of 12.5 m Easting x 12.5 m Northing x 12 m Elevation was selected for the block 
model. The selected block size was based on the geometry of the domain interpretation and the data configuration. 
The mining cost estimate for the pit optimization process is based on studies developed by NCL during 2018. The 
estimated  average  project  mining  cost  was  separated  into  various  components  such  as  fuel,  explosives,  tires, 

37 

 
parts, salaries and wages, benchmarked against similar current operations in Chile. Each component was updated 
for third quarter 2018 prices and the exchange rate from Chilean Pesos to US dollars. This resulted in an estimated 
mining  cost  of  approximately  $1.75/t.  Estimated  metal  prices,  processing  costs,  refining  costs,  and  processing 
recoveries were provided to NCL by Capstone. A number of calculations were performed in the model in order to 
determine the NSR of each individual block. The internal (or mill) cut-off of $7.53/t milled incorporates all operating 
costs except mining. This internal cut-off is applied to material contained within an economic pit shell, where the 
decision to mine a given block was determined by the pit optimization and was applied to all of the Mineral Reserve 
estimates. Marginal ore was calculated for the same  $7.53/t cut-off,  but for a NSR determined at higher metal 
prices. Final slope angles used for the pit optimization process were a result of multiple iterations and analysis 
carried out by the NCL mining team and geotechnical specialists Derk Ingeniería y Geología Ltda (“Derk”). The 
original block model was based on an ore percentage with dimensions of 12.5 m x 12.5 m x 12 m, resulting in a 
1,875  m3  block volume; this means that every block  has a defined “ore” proportion with an ore density, and a 
corresponding “waste” proportion with a waste density. To accommodate selective mining methods, any resource 
block with an ore percentage that was less than 10% was treated as waste. Blocks with an ore percentage that 
was higher than 90% were diluted with waste such that all high-ore blocks were considered to contain only 90% 
ore. Selective mining therefore will be performed on those blocks that have an ore percentage of between 10% 
and 90%. The Santo Domingo Mineral Reserves estimate is summarized in  Table 6. 

In the opinion of NCL, the factors most likely to significantly affect the Mineral Reserves estimate are metallurgical 
recoveries and operating costs (fuel, energy and labour). NCL notes that the base price and changes in metals  
prices do not affect the Mineral Reserves estimate to any significant degree, despite being the most important 
factor for revenue calculation. A revenue factor of 0.84 was used for the LG shell that was employed as the guide 
for  the  practical  design  for  both  the  Santo  Domingo  and  Iris  Norte  pits.  This  revenue  factor  is  relatively 
conservative,  allowing  for  broad  swings  in  metals  prices  without  significantly  impacting  the  Mineral  Reserves 
estimate.

NOTE: Mineral Reserves have an effective date of 14 November 2018 and were prepared by Mr. Carlos Guzman, CMC, an 
employee of NCL. Mineral Reserves are reported as constrained within Measured and Indicated pit designs and supported 
by a mine plan featuring variable throughput rates and cut-off optimization. The pit designs and mine plan were optimized 
using the following economic and technical parameters: metal prices of US$3.00/lb Cu, US$1,280/oz Au and US$100/dmt 
of Fe concentrate; average recovery to concentrate is 93.4% for Cu and 60.1% for Au, with magnetite concentrate recovery 
varying  on  a  block-by-block  basis;  copper  concentrate  treatment  charges  of  US$80/dmt,  U$0.08/lb  of  copper  refining 
charges,  US$5.0/oz  of  gold  refining  charges,  US$33/wmt  and  US$20/dmt  for  shipping  copper  and  iron  concentrates 
respectively; waste mining cost of $1.75/t, mining cost of US$1.75/t ore and process and G&A costs of US$7.53/t processed; 
average pit slope angles that range from 37.6º to 43.6º; a 2% royalty rate assumption and an assumption of 100% mining 
recovery. Rounding as required by reporting standards may result in apparent summation differences between tonnes, grade 
and  contained  metal  content.  Tonnage  measurements  are  in  metric  units.  Copper  and  iron  grades  are  reported  as 
percentages, gold as grams per tonne. Contained gold ounces are reported as troy ounces, contained copper as million 
pounds and contained iron as metric million tonnes.

4 – RISK FACTORS 

Capstone is subject to a number of significant risks due to the nature of our business which includes acquisition, 
financing, exploration, development and operation of mining properties. You should carefully consider the risks 
and uncertainties described below and other information contained in this Annual Information Form before deciding 
whether to invest in Capstone common shares. The risks and uncertainties described below could have a material 
adverse effect on our business, financial condition or results of operations, and the trading price of our common 
shares may decline and investors may lose all or part of their investment. We cannot give assurance that we can 
control or will successfully address these risks or other unknown risks that may affect our business. Additional 
risks or uncertainties not presently known to Capstone or that Capstone currently considers immaterial may also 
impair our business operations. 

Mining is inherently dangerous and subject to conditions or events beyond Capstone’s control. 

Capstone’s  operations  are  subject  to  all  the  hazards  and  risks  normally  encountered  in  the  exploration, 
development, care and maintenance of mining operations and production of copper and other metals, including, 
without  limitation,  workplace  accidents,  fires,  including  wildfires,  power  outages,  labour  disruptions,  flooding, 
explosions, cave-ins, landslides, ground or stope failures, tailings dam failures and other geotechnical instabilities, 
weather  events,  access  to  water,  equipment  failure  or  structural  failure,  metallurgical  and  other  processing 
problems  and  other  conditions  involved  in  the  mining  of  minerals,  any  of  which  could  result  in  damage  to,  or 
destruction of, our mines, mineral properties, plants and equipment, personal injury or loss of life, environmental 
damage, delays in mining, increased production costs, care and maintenance costs, asset write-downs, monetary 
losses, legal liability and governmental action. Our mines have large tailings dams which could fail as a result of 
extreme weather events, seismic activity or for other reasons. The occurrence of any of these events could result 
in a prolonged interruption in Capstone’s operations, increased costs for asset protection or care and maintenance 
activities  that  would  have  a  material  adverse  effect  on  Capstone’s  business,  financial  condition,  results  of 
operations and prospects. 

Wildfires and inclement weather conditions, whether occurring at Capstone’s sites, adjacent lands, or supplier and 
downstream sites, may impact our ability to operate, transport or access and supply sites, and increase overall 
costs  or  impact  Capstone’s  financial  performance.  In  severe  circumstances,  civil  authorities  may  impose 
evacuation orders. Our sites in Arizona and Mexico are subject to drought conditions and create a higher exposure 
to wildfire risk. 

Changes  in  the  market  price  of  copper  and  other  metals  could  negatively  affect  the  profitability  of  the 
Company’s  operations  and  financial  condition  and  negatively  impact  Mineral  Reserve  estimations  or 
render our business, or part thereof, no longer economically viable. Our business is largely concentrated 
in the copper mining industry, and, as a result, may be negatively impacted by fluctuation in the copper 
mining industry generally.  

Capstone is concentrated in the copper mining industry, and as such our profitability will be sensitive to changes 
in, and our performance will depend, to a greater extent, on the overall condition of the copper mining industry. 
The commercial viability of Capstone’s properties and Capstone’s ability to sustain operations is dependent on, 
amongst  other  things,  the  market  price  of  copper,  zinc,  lead,  gold,  silver  and  molybdenum.  Depending  on  the 
expected price for any minerals produced, Capstone may determine that it is impractical to continue commercial 
production at the Pinto Valley Mine or the Cozamin Mine, or to develop the Santo Domingo Project. A reduction 
in the market price of copper, zinc, lead, gold, silver, iron, or molybdenum may prevent Capstone’s properties from 
being economically mined or result in the write-down of assets whose value is impaired as a result of low metals 
prices. The market price of copper, zinc, lead, gold, silver, iron and molybdenum is volatile and is impacted by 
numerous factors beyond Capstone’s control, including, amongst others:  

the supply/demand balance for any given metal;  
international economic and political conditions;  
tariffs or taxes imposed by governments; 

• 
• 
• 
•  expectations of inflation or deflation;  

39 

 
increased production due to new mine developments;  

international currency exchange rates;  
interest rates;  

• 
• 
•  global or regional consumptive patterns;  
•  speculative activities;  
•  global or regional crises or breakout and spread of contagious illnesses or diseases; 
• 
•  decreased production due to mine closures;  
• 
improved mining and production methods;  
•  availability and costs of metal substitutes;  
•  new technologies that use other materials in place of our products;  
•  metal stock levels maintained by producers and others; and  
• 

inventory carry costs.  

The effect of these factors on the price of base and precious metals cannot be accurately predicted and there can 
be no assurance that the market price of these metals will remain at current levels or that such prices will improve. 
A decrease in the market price of copper, zinc, lead, gold, silver or molybdenum would affect the profitability of 
the Pinto Valley Mine and the Cozamin Mine and could affect Capstone’s ability to finance the exploration and 
development of our other properties, which would have a material adverse effect on Capstone’s business, financial 
condition, results of operations and prospects.  

Within this  industry context, the Company’s strategy  is to  maintain a cost structure that  will allow  it to  achieve 
adequate levels of cash flow during the low point in the copper price cycle. Circumstances may arise, however, 
where increased certainty of cash flows is considered more important to long term value creation than providing 
investors short term exposure to the volatility of metal prices. In these circumstances, the Company may elect to 
fix  prices  within  a  contractual  quotational  period  and/or  to  lock  in  future  prices  through  the  variety  of  financial 
derivative  instruments  available.  There  are,  however,  risks  associated  with  programs  to  fix  prices  including, 
amongst other things, the potential risk that the counter party will not be able to meet their obligations, the risk of 
opportunity  losses  in  the  event  of  an  increase  in  the  world  price  of  the  commodity,  the  possibility  that  rising 
operating costs will make delivery into hedged positions uneconomic, and production interruption events.  

A global pandemic could cause temporary closure of businesses in regions that are significantly impacted by the 
health crises, or cause governments to take preventative measures such as the closure of points of entry, including 
ports and borders. These restrictive measures along with market uncertainty could cause an economic slowdown 
resulting in a decrease in the demand for copper and have a negative impact on base metal prices. The recent 
outbreak  of  the  novel  coronavirus  (COVID-19)  has  had  a  negative  impact  on  copper  prices  and  governmental 
actions to contain the outbreak may impact our ability to transport or market our concentrate or cause disruptions 
in our supply chains or interruption of production. A material spread of COVID-19 in jurisdictions where we operate 
could impact our ability to staff operations. 

Financial covenant compliance risks  

The terms of Capstone’s amended senior secured corporate revolving credit facility requires that Capstone satisfy 
various affirmative and negative covenants and meet certain quarterly financial ratio tests. These covenants limit, 
amongst other things, Capstone’s ability to incur further indebtedness if doing so would cause it to fail to meet 
certain financial ratio tests. They also limit the ability of Capstone to create certain liens on certain assets or to 
engage in certain types of transactions. A failure to comply with these covenants, including a failure to meet the 
financial tests or ratios, could result in an event of default and allow lenders to accelerate the debt repayment.  

Surety bonding risks  

Capstone secures its obligations for reclamation and closure costs with surety bonds provided by leading global 
insurance  companies  in  favour  of  regulatory  authorities  in  Arizona.  The  regulators  could  increase  Capstone’s 
bonding  obligations  for  reclamation  and  closure  activities.  Further,  these  surety  bonds  include  the  right  of  the 
surety bond provider to terminate the relationship with Capstone on providing notice of up to 90 days. The surety 

40 

 
bond provider would, however, remain liable to the regulatory authorities for all bonded obligations existing prior 
to  the  termination  of  the  bond  in  the  event  Capstone  failed  to  deliver  alternative  security  satisfactory  to  the 
regulator.  

Capstone remains as an Indemnitor for Minto Explorations Ltd.’s surety bond obligations in the Yukon and could 
be liable for the bonded obligations in the event Minto Explorations Ltd. does not satisfy those obligations.  

Financing requirement risks 

Capstone may require substantial additional capital to accomplish its exploration and development plans and fund 
strategic growth and there can be no assurance that financing will be available on terms acceptable to Capstone, 
or at all. Capstone may require substantial additional financing to advance the Pinto Valley Mine, and the Cozamin 
Mine to achieve designed production rates, to finance potential strategic acquisitions required for growth and to 
accomplish any exploration and development plans for the Santo Domingo Project. These financing requirements 
could adversely affect Capstone’s ability to access the capital markets in the future. Failure to obtain sufficient 
financing,  or  financing  on  terms  acceptable  to  Capstone,  may  result  in  a  delay  or  indefinite  postponement  of 
exploration, development or production at one or more of our properties. Additional financing may not be available 
when needed and the terms of any agreement could impose restrictions on the operation of our business. Failure 
to raise financing when needed could have a material adverse effect on our business, financial condition, results 
of operations and prospects.  

Our operations are subject to geotechnical challenges, which could adversely impact our production and 
profitability. 

No  assurances  can  be  given  that  unanticipated  adverse  geotechnical  and  hydrological  conditions  such  as 
landslides, cave-ins, rock falls, slump, ground or stope failures, tailings storage facility failures or releases and pit 
wall failures will not occur in the future or that such events will be detected in advance. Due to the age of our mines 
and  more  complex  deposits,  Capstone’s  pit  is  becoming  deeper  resulting  in  higher  pitwalls  and  underground 
environments are becoming more complex, potentially increasing the exposure to geotechnical instabilities and 
hydrological  impacts.  Geotechnical  instabilities  can  be  difficult  to  predict  and  are  often  affected  by  risks  and 
hazards outside of Capstone’s control, such as seismic activity and severe weather events, which may lead to 
periodic floods, mudslides, and wall instability. 

Capstone’s mine sites have multiple active and inactive tailings storage facilities, including upstream raised dams 
and legacy facilities inherited through acquisition activities. Our tailings storage facilities have been designed by 
professional  engineering  firms  specializing  in  this  activity.  Capstone  continues  to  review  and  enhance  existing 
practices in line with international best practices; however, no assurance can be given that these events will not 
occur in the future. Tailings storage facilities have the risk of failure due extreme weather events, seismic activity 
or for other reasons. The failure of tailings dam facilities or other impoundments could cause severe or catastrophic 
environmental and property damage or loss of life. Geotechnical or tailings storage facility failures could result in 
the  suspension  of  our  operations,  limited  or  restricted  access  to  sites,  government  investigations,  remediation 
costs,  increased  monitoring  costs  and  other  impacts,  which  could  result  in  a  material  adverse  effect  on  our 
operational results and financial position. 

Capstone’s ability to acquire properties for growth.  

The life of any mine is limited by its Mineral Reserves. As we seek to replace and expand our Mineral Reserves 
through  exploration,  acquisition  of  interests  in  new  properties  or  of  interests  in  companies  which  own  the 
properties, we encounter strong competition from other companies in connection with the acquisition of properties. 
This competition may limit our ability to adequately replace Mineral Reserves.  

The sale of our metals is subject to counterparty and market risks.  

Capstone  enters  into  concentrate  off-take  agreements  whereby  a  percentage  of  planned  production  of  copper 
concentrate produced from our mines is committed to various external parties throughout the calendar year. If any 
counterparty to any off-take or forward sales agreement does not honour such arrangement, or should any such 

41 

 
counterparty become insolvent, Capstone may incur losses on the production already shipped or be forced to sell 
a greater volume of our production in the spot market, which is subject to market price fluctuations. In addition, 
there can be no assurance that Capstone will be able to renew any of our off-take agreements at economic terms, 
or  at  all,  or  that  Capstone’s  production  will  meet  the  qualitative  and  quantitative  requirements  under  such 
agreements.  

We may face market access restrictions or tariffs.  

Capstone  could  experience  market  access  interruptions  or  trade  barriers  due  to  policies  or  tariffs  of  individual 
countries, or the actions of certain interest groups to restrict the import of certain commodities. Regional and global 
crises including but not limited the breakout of contagious illnesses and global pandemics could significantly impact 
our ability to or costs to market and transport our concentrate. Restrictions or interruptions in Capstone’s ability to 
transport concentrate across country borders and globally could materially affect our business operations.  Our 
exported  copper  concentrate,  or  the  supplies  we  import  may  also  be  impacted,  which  may  impair  the 
competitiveness of our business.  

Fluctuations in foreign currency exchange rates could have an adverse effect on Capstone’s business, 
financial condition, results of operations and prospects.  

Fluctuations in the Canadian dollar or Mexican peso relative to the US dollar could significantly affect our business, 
financial condition, results of operations and prospects. Exchange rate movements can have a significant impact 
on Capstone as all of Capstone’s revenue is received in US dollars but a portion of the Company’s operating and 
capital  costs  are  incurred  in  Canadian  dollars  and  Mexican  pesos.  Also,  Capstone  is  exposed  to  currency 
fluctuations in the Chilean peso relating to expenditures for the Santo Domingo Project. As a result, a strengthening 
of these currencies relative to the US dollar will reduce Capstone’s profitability and affect its ability to finance its 
operations.  While  Capstone  does  not  currently  have  any  foreign  currency  contracts  in  place  to  hedge  against 
currency risk, circumstances may arise in the future where this may be an appropriate strategy to manage costs 
and risks.  

General  economic  conditions  or  changes  in  consumption  patterns  may  adversely  affect  Capstone’s 
growth and profitability.  

Many industries, including the base and precious metals mining industry, are impacted by global market conditions. 
Some of the key impacts of financial market turmoil include contraction in credit markets resulting in an increase 
in credit risk, devaluations and high volatility in global equity, commodity, foreign exchange and metals markets, 
and a lack of market liquidity. A slowdown in the financial markets or other economic conditions, including, but not 
limited  to,  reduced  consumer  spending,  increased  unemployment  rates,  deteriorating  business  conditions, 
inflation, deflation, volatile fuel and energy costs, increased consumer debt levels, lack of available credit, changes 
in  interest  rates  and  changes  in  tax  rates  may  adversely  affect  Capstone’s  growth  and  profitability  potential. 
Specifically:  

•  a global credit/liquidity issue could impact the cost and availability of financing and our overall liquidity;  
•  volatility  of  prices  for  copper,  zinc,  lead,  gold,  silver,  iron  and/or  molybdenum  may  impact  our  future 

revenues, profits and cash flows;  

•  recessionary pressures could adversely impact demand for our production;  
•  volatile energy prices, commodity and consumables prices and currency exchange rates could negatively 

impact potential production costs; and  

•  devaluation and volatility of global stock markets could impact the valuation of Capstone’s securities, which 

may impact Capstone’s ability to raise funds through future issuances of equity.  

These factors could have a material adverse effect on our business, financial condition, results of operations and 
prospects.  

42 

 
 
 
Capstone’s Mineral Resources and Mineral Reserves are estimates and are subject to uncertainty.  

Our  Mineral  Resources  and  Mineral  Reserves  are  estimates  and  depend  upon  geological  interpretation  and 
statistical  inferences  drawn  from  drilling  and  sampling  analysis,  which  may  prove  to  be  inaccurate.  Actual 
recoveries of copper, zinc, lead, gold, silver, iron and molybdenum from mineralized material may be lower than 
those indicated by test work. Any material change in the quantity of mineralization, grade or stripping ratio, may 
affect the economic viability of Capstone’s properties. In addition, there can be no assurance that metal recoveries 
in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production. 
Notwithstanding pilot plant tests for metallurgy and other factors, there remains the possibility that the ore may not 
react in commercial production in the same manner as it did in testing. Mineral Resources that are not Mineral 
Reserves  do  not  have  demonstrated  economic  viability.  Mining  and  metallurgy  are  inexact  sciences  and, 
accordingly, there always remains an element of risk that a mine may not prove to be commercially viable.  

Until a deposit is  actually  mined  and processed, the  quantity  of  Mineral Resources and  Mineral Reserves and 
grades must be considered as estimates only. In addition, the quantity of Mineral Resources and Mineral Reserves 
may  vary  depending  on,  amongst  other  things,  metal  prices,  cut-off  grades  and  operating  costs.  Any  material 
change in quantity of Mineral Reserves, Mineral Resources, grade, percent extraction of those Mineral Reserves 
recoverable by underground mining techniques or the stripping ratio for those Mineral Reserves recoverable by 
open pit mining techniques may affect the economic viability of Capstone’s mining projects.  

We  face  added  risks  and  uncertainties  of  operating  in  foreign  jurisdictions,  including  changes  in 
regulation and policy, and community interest or opposition.  

Capstone’s business operates in a number of foreign countries where there are added risks and uncertainties due 
to the different economic, cultural and political environments. Our mineral exploration and mining activities may 
be adversely affected by political instability and changes to government regulation relating to the mining industry. 
Changes in governmental leadership in the US, Chile, and Mexico, could impact Capstone’s operations and local 
societal conditions. Other risks of foreign operations include political or social unrest, labour disputes and unrest, 
invalidation  of  governmental  orders and permits, corruption, organized crime, theft, war, civil disturbances  and 
terrorist actions, arbitrary changes in law or  policies of particular countries (including nationalization of mines), 
trade disputes, foreign taxation, price controls, delays in obtaining or renewing or the inability to obtain or renew 
necessary environmental permits, opposition to mining from local communities and environmental or other non-
governmental  organizations,  social  perception  impacting  our  social  license  to  operate,  limitations  on  foreign 
ownership, limitations on the repatriation of earnings, limitations on mineral exports and increased financing costs. 
Local economic conditions, including higher incidences of criminal activity and violence in areas of Mexico can 
also  adversely  affect  the  security  of  our  people,  operations  and  the  availability  of  supplies.  Capstone  may 
encounter  social  and  community  issues  including  but  not  limited  to  public  expression  against  our  activities, 
protests, road blockages, work stoppages, or other forms of expression, which may have a negative impact on our 
reputation and operations or projects. Opposition to  our mining  activities by  local  landowners, communities, or 
activist groups may cause significant delays or increased costs to operations, and the advancement of exploration 
or  development  projects,  and  could  require  Capstone  to  enter  into  agreements  with  such  groups  or  local 
governments. 

In addition, risks of operations in Mexico include extreme fluctuations in currency exchange rates, high rates of 
inflation, significant changes in laws and regulations including but not limited to tax regulations, hostage taking 
and  expropriation.  These  risks  may  limit  or  disrupt  Capstone’s  projects,  reduce  financial  viability  of  local 
operations, restrict the movement of funds or result in the deprivation of contract rights or the taking of property 
by  nationalization  or  expropriation  without  fair  compensation.  There  can  be  no  assurance  that  changes  in  the 
government  or  laws  or  changes  in  the  regulatory  environment  for  mining  companies  or  for  non-domiciled 
companies  will  not  be  made  that  would  adversely  affect  Capstone’s  business,  financial  condition,  results  of 
operation and prospects.  

43 

 
 
Differences  in  interpretation  or  application  of  tax  laws  and  regulations  or  accounting  policies  and  rules  and 
Capstone’s application of those tax laws and regulations or accounting policies and rules where the tax impact to 
the  Company  is  materially  different  than  contemplated  may  occur  and  adversely  affect  Capstone’s  business, 
financial condition, results of operation and prospects.  

Resource nationalism  

Governments  in  certain  jurisdictions  struggle  with  depressed  economies  and  as  a  result  have  targeted  mining 
companies  for  additional  revenue  by  way  of  increased  economic  rent  for  the  exploitation  of  resources  in  their 
countries.  Many  countries  including  Chile  and  Mexico  have  recently  implemented  changes  to  their  respective 
mining regimes. Future changes could include things such as, but not limited to, law affecting foreign ownership 
and take-overs, mandatory government participation, taxation and royalties, working conditions, export duties or 
repatriation of income or return of capital.  

Our  operations  are  subject  to  significant  governmental  regulation,  which  could  significantly  limit  our 
exploration and production activities.  

Capstone’s mineral exploration, development and operating activities are subject to governmental approvals and 
various laws and regulations governing development, operations, taxes, labour standards and occupational health, 
mine safety, toxic substances, land use, water use and land claims affecting local communities, First Nations and 
Aboriginal populations. The liabilities and requirements associated with the laws and regulations related to these 
and  other  matters  may  be  costly  and  time-consuming  and  may  restrict,  delay  or  prevent  commencement  or 
continuation of exploration or production operations. We cannot provide definitive assurance that we have been 
or will be at all times in compliance with all applicable laws and regulations and governmental orders. Failure to 
comply with applicable laws, regulations and governmental orders may result in the assessment of administrative, 
civil  and  criminal  penalties,  the  imposition  of  cleanup  and  site  restoration  costs  and  liens,  the  issuance  of 
injunctions  to  limit  or  cease  operations,  the  suspension  or  revocation  of  permits  or  authorizations  and  other 
enforcement  measures  that  could  have  the  effect  of  limiting  or  preventing  production  from  our  operations. 
Capstone may incur material costs and liabilities resulting from claims for damages to property or injury to persons 
arising from Capstone’s operations. If Capstone is pursued for sanctions, costs and liabilities in respect of these 
matters, Capstone’s mining operations and, as a result, Capstone’s financial performance, financial position and 
results of operations, could be materially and adversely affected.  

In addition, 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 that could limit or curtail our exploration, development or production. 
This risk may increase following changes to government leadership or governing parties, or through increasing 
societal pressures. Amendments to current laws, tax regimes, regulations and permits governing operations and 
activities of mining and exploration companies, or the more stringent implementation thereof, could have a material 
adverse impact on Capstone and increase our exploration expenses, capital expenditures, ability to attract funds, 
or production costs or reduce production at our producing properties or require abandonment or delays in exploring 
or developing our properties.  

Capstone  is  required  to  obtain,  maintain  and  renew  environmental,  construction  and  mining  permits, 
which is often a costly, time-consuming and uncertain process.  

Mining companies, including Capstone, need 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  Capstone,  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 current and future operations on the environment and to take steps to avoid or mitigate 
those impacts. For example, additional permits will be required to fully exploit the resources at Pinto Valley and 
Cozamin. There is a risk that Capstone will not be able to obtain such permits or that obtaining such permits will 
require more time and capital than anticipated.  

44 

 
Permit terms and conditions can also impose restrictions on how we operate and limits our flexibility in developing 
our mineral properties. Many of Capstone’s permits are subject to renewal from time to time, and renewed permits 
may contain more restrictive conditions than Capstone’s existing permits. In addition, we may be required to obtain 
new permits to expand our operations, and the grant of such permits may be subject to an expansive governmental 
review of our operations. Alternatively, we may not be successful in obtaining such permits, which could prevent 
Capstone  from  commencing,  extending  or  expanding  operations  or  otherwise  adversely  affect  Capstone’s 
business,  financial  condition,  results  of  operation  and  prospects.  Further,  renewal  of  our  existing  permits  or 
obtaining new permits may be more difficult if we are not able to comply with our existing permits. Applications for 
permits, permit area expansions and permit renewals may be subject to challenge by interested parties, which can 
delay or prevent receipt of needed permits. The permitting  process can also vary by jurisdiction  in terms of its 
complexity and likely outcomes.  

Accordingly, permits required for Capstone’s operations may not be issued, maintained or renewed in a timely 
fashion or at all, may be issued or renewed upon conditions that restrict Capstone’s ability to operate economically, 
or may be subsequently revoked. Design and construction standards for tailings storage facilities may become 
more restricted in the future, impacting our mines’ ability to expand, operate, or renew permits and as a result, 
considerable  capital  expenditures  may  be  required  to  comply  with  new  standards,  regulations  and  permitting 
requirements.  Any  such  failure  to  obtain,  maintain  or  renew  permits,  or  other  permitting  delays  or  conditions, 
including  in  connection  with  any  environmental  impact  analyses,  could  have  a  material  adverse  effect  on 
Capstone’s business, results of operations, financial condition and prospects. At the end of 2018, Cozamin mine 
increased its Mineral Reserves and will require additional tailings capacity to support the extension of operations. 
Cozamin is studying several potential tailings storage facility design options which will require additional permits 
and regulatory approvals for construction activities. The proposed option could be more costly to design, construct, 
or operate, and may impact the footprint of the mine plan boundaries. The current tailings facility will eventually 
reach  an  optimal  capacity  limit,  after  which  further  expansion  stages  will  not  be  pursued.  This  may  result  in 
additional requirements for maintaining the tailings dam post-operation and pre-reclamation activities.  

Climatic  conditions  can  affect  our  operations  at  the  Pinto  Valley  and  Cozamin  Mines  and  our  Santo 
Domingo Project, or current and future development projects.  

The potential physical impacts of climate change on our operations are highly uncertain and are particular to the 
geographic circumstances in areas in which we operate. These may include changes in rainfall and storm patterns 
and  intensities,  water  shortages,  changing  sea  levels  and  changing  temperatures.  Additionally,  global  climatic 
conditions can impact the capacity for insurance available in the market which could have a negative effect on 
Capstone’s financial condition or risk exposure. 

Arizona  can  be  subject  to  periods  of  drought.  Operations  at  the  Pinto  Valley  Mine  require  water  for  normal 
operations.  Capstone  has  entered  into  a  Water  Supply  Agreement  with  BHP  Copper,  but  such  agreement  is 
subject to water availability and BHP Copper’s own requirements. A lack of necessary water for a prolonged period 
of time could affect operations at the Pinto Valley Mine and materially adversely affect our results of operations. 
Arizona can also be subject to significant rainfall events which could result in excess water or flooding of the pit, 
tailings  storage  facilities  or  other  significant  areas  at  the  Pinto  Valley  Mine  adversely  affecting  our  results  of 
operations or causing adverse impacts.  

Operations at the Cozamin Mine are also subject to extreme adverse weather conditions including, but not limited 
to, flooding and drought. The rainy season extends from June until September with an average annual precipitation 
of approximately 500mm. Drought has also been prevalent in Central Mexico for years and the effects of lack of 
water might disrupt normal process operations.  

Extreme weather conditions in Chile, including but not limited to flooding, may have adverse effects on the ability 
of the Santo Domingo project to advance development.  

45 

 
Changes in climate change regulatory regime could adversely affect our business.  

Climate change is an international concern and as a result poses risk of both climate changes and government 
policy in which governments are introducing climate change legislation and treaties at all levels of government that 
could result in increased costs, and therefore, decreased profitability at some of our operations or projects. As the 
regulatory  requirements  are  evolving  there  is  uncertainty  to  the  requirements.  Mining  is  an  energy-intensive 
business and can result in an increased carbon footprint. Regulation specific to greenhouse gases, emission levels 
and  energy  efficiency  is  becoming  more  stringent.  Carbon-pricing  mechanisms  may  be  introduced  in  the 
jurisdictions we operate or conduct business. New legislation and increased regulation could impose costs on our 
operations, customers, and suppliers, including increased energy, capital equipment, environmental monitoring 
and reporting and other costs to comply with such regulations. The trend towards more stringent regulations and 
carbon-pricing mechanisms aimed at reducing the effects of climate change could impact our decision to pursue 
future opportunities, or maintain our existing operations, which could have an adverse effect on our business.  

Our operations are subject to stringent environmental laws and regulations that could significantly limit 
our ability to conduct our business.  

Our  operations  are  subject  to  various  laws  and  regulations  governing  the  protection  of  the  environment, 
exploration, development, production, taxes, labour standards, occupational health, waste disposal, tailings facility 
management,  safety  and  other  matters.  Environmental  legislation  provides  for  restrictions  and  prohibitions  on 
spills, releases or emissions of various substances produced in association with certain mining operations, such 
as spills or excessive seepage or dust from tailings storage facilities, which could result in environmental pollution. 
A breach of such legislation may result in the imposition of fines and penalties. In addition, certain of our operations 
require the submission and approval of environmental impact assessments. Environmental legislation is evolving 
in  the  direction  of  stricter  standards  and  enforcement,  higher  fines  and  penalties  for  non-compliance,  more 
stringent  environmental  assessments  of  proposed  projects  and  a  heightened  degree  of  responsibility  for 
companies  and  their  directors,  officers  and  employees.  Compliance  with  changing  environmental  laws  and 
regulations may require significant capital outlays, including but not limited to revisions to tailings facility designs, 
obtaining  additional  permits,  installation  of  additional  equipment,  or  remedial  actions  and  may  cause  material 
changes or delays in, or the cancellation of, our exploration programs or current operations.  

Land reclamation and mine closure requirements may be burdensome and costly.  

Land  reclamation  and  mine  closure  requirements  are  generally  imposed  on  mining  companies,  which  require 
Capstone, amongst other things, to  minimize the  effects of land disturbance.  Additionally, Capstone has  lease 
agreements, and may enter into agreements in the future, which may require environmental restoration activities 
at transportation, storage and shipping facilities such as the Skagway Ore Terminal and the San Manuel Transload 
Facility or other properties. Further, the San Manuel Arizona Railroad Company may have increased reclamation 
requirements  as  a  rail  transportation  company.  Such  requirements  may  include  controlling  the  discharge  of 
potentially dangerous effluents from a site and restoring a site’s landscape to its pre-exploration form. The actual 
costs  of  reclamation  and  mine  closure  are  uncertain  and  planned  expenditures  may  differ  from  the  actual 
expenditures required. Through acquisition activities Capstone may discover or inherit historic tailings or waste 
deposits  which  may  require  further  remediation  activities,  including  but  not  limited  to  the  historic  mining  and 
processing operations at Chiripa-La Gloria arroyo at the Cozamin Mine. Therefore, the amount that we are required 
to  spend  could  be  materially  higher  than  current  estimates.  Any  additional  amounts  required  to  be  spent  on 
reclamation and mine closure may have a material adverse effect on our financial performance, financial position 
and results of operations and may cause Capstone to alter Capstone’s operations. Although we include liabilities 
for estimated reclamation and mine closure costs in our financial statements and Life of Mine models, it may be 
necessary to spend more than what is projected to fund required reclamation and mine closure activities.  

46 

 
 
 
There are uncertainties and risks related to the potential development of the Santo Domingo Project.  

The development of the Santo Domingo Project will require securing financing and equity partnerships. Capstone's 
ability  to  raise  its  equity  contribution  to  the  Santo  Domingo  Project  may  be  influenced  by  future  prices  of 
commodities and the market for project debt. 

Various factors may influence the ability to further enhance the value of the Santo Domingo project including but 
not limited to the expected timing for commencement of construction, the realization of Mineral Reserve estimates, 
grade or recovery rates, an increase in capital requirements or construction expenditures, the timing and terms of 
a power purchase agreement, title disputes, claims  and limitations on  insurance coverage  or extreme weather 
events.  Delays  to  the  development  of  the  Santo  Domingo  project  may  be  influenced  by  factors  such  as 
dependence  on  key  personnel,  availability  of  contractors,  accidents,  labour  pool  constraints,  labour  disputes, 
availability of infrastructure, objections by the communities or environmental lobby of the Santo Domingo Project 
and associated infrastructure and other risks of the mining industry. These events could have a material adverse 
effect on Capstone’s financial condition, business, operating results and prospects. 

Any changes in the Santo Domingo Project parameters or development and construction delays may impact the 
timing  and  amount  of  estimated  future  production,  costs  of  production,  success  of  mining  operations, 
environmental compliance, and reclamation requirements.  

The costs, timing and complexities of developing Capstone’s projects may be greater than anticipated.  

Cost  estimates  may  increase  significantly  as  more  detailed  engineering  work  is  completed  on  a  project.  It  is 
common  in  mining  operations  to  experience  unexpected  costs,  problems  and  delays  during  construction, 
development and mine start-up. Accordingly, we cannot provide assurance that our activities will result in profitable 
mining operations at our mineral properties. If there are significant delays in when these projects are completed 
and are producing on a commercial and consistent scale, or their capital costs were to be significantly higher than 
estimates, these events could have a significant adverse effect on Capstone’s results of operation, cash flow from 
operations and financial condition.  

Mineral rights or surface rights to our properties could be challenged, and, if successful, such challenges 
could have a material adverse effect on our production and our business, financial condition, results of 
operations and prospects.  

Title  to  Capstone’s  properties  may  be  challenged  or  impugned.  Our  property  interests  may  be  subject  to  prior 
unregistered agreements or transfers and title may be affected by undetected defects. Surveys have not been 
carried out on the majority of our properties and, therefore, in accordance with the laws of the jurisdiction in which 
such properties are situated, their existence and area could be in doubt.  

A  claim  by  a  third  party  asserting  prior  unregistered  agreements  or  transfer  on  any  of  Capstone’s  properties, 
especially  where  Mineral  Reserves  have  been  located,  could  result  in  Capstone  losing  a  commercially  viable 
property. Even if a claim is unsuccessful, it may potentially affect Capstone’s current operations due to the high 
costs  of  defending  against  the  claim  and  its  impact  on  Capstone’s  resources.  Title  insurance  is  generally  not 
available for mineral properties and Capstone’s ability to ensure that Capstone has obtained a secure claim to 
individual  mineral  properties  or  mining  concessions  may  be  severely  constrained.  We  rely  on  title  information 
and/or representations and warranties provided by our grantors. If we lose a commercially viable property, such a 
loss could lower our future revenues or cause Capstone to cease operations if the property represented all or a 
significant portion of our Mineral Reserves at the time of the loss.  

It may be difficult for Capstone to find and hire qualified people in the mining industry who are situated in 
Arizona, Mexico and Chile or to obtain all of the necessary services or expertise in Arizona, Mexico and 
Chile or to conduct operations on Capstone’s projects at reasonable rates.  

If qualified people and services or expertise cannot be obtained in Arizona, Mexico and Chile, we may need to 
seek and obtain those services from people located outside of these areas, which will require work permits and 
compliance with applicable laws and could result in delays and higher costs.  

47 

 
We are dependent on key management personnel.  

We are very dependent upon the personal efforts and commitment of our existing management and our current 
operations and future prospects depend on the experience and knowledge of these individuals. Capstone does 
not maintain any “key person” insurance. To the extent that one or more of Capstone’s members of management 
are unavailable for any reason, or should Capstone lose the services of any of them, a disruption to Capstone’s 
operations could result, and there can be no assurance that Capstone will be able to attract and retain a suitable 
replacement.  

Our directors and officers may have interests that conflict with Capstone’s interests.  

Certain of Capstone’s directors and officers also serve as directors or officers, or have significant shareholdings 
in,  other  companies  that  are  similarly  engaged  in  the  business  of  acquiring,  developing  and  exploiting  natural 
resource properties. To the extent that such other companies may participate in ventures which Capstone may 
participate in, or in ventures which Capstone may seek to participate in, our directors and officers may have a 
conflict  of  interest  in  negotiating  and  concluding  terms  respecting  the  extent  of  such  participation.  In  all  cases 
where our directors and officers have an interest in other companies, such other companies may also compete 
with Capstone for the acquisition of mineral property investments. As a result of these conflicts of interest, we may 
not have an opportunity to participate in certain transactions, which may have a material adverse effect on our 
business, financial condition, results of operation and prospects.  

Corruption and bribery risk  

Capstone is required to comply with anti-corruption and anti-bribery laws of various countries including, Canada, 
US, Mexico and Chile. In recent years there has been an increase in enforcement and severity of penalties under 
such  laws.  A  company  may  be  found  liable  for  violations  by  employees,  contractors  and  third  party  agents. 
Capstone has implemented policies and taken measures including training to mitigate the risk of non-compliance, 
however, such measures are not always effective in ensuring that Capstone, its employees, contractors and third 
party agents comply strictly with such laws. If Capstone is found to be in violation of such laws, this may result in 
significant penalties, fines and/or sanctions resulting in a material adverse effect on Capstone’s reputation and 
financial results.  

Capstone’s  insurance  does  not  cover  all  potential  losses,  liabilities  and  damage  related  to  Capstone’s 
business and certain risks are uninsured or uninsurable.  

In  the  course  of  exploration,  development  and  production  of  mineral  properties  and  in  the  conduct  of  our 
operations, certain risks, including but not limited to rock bursts, cave-ins, environmental incidents, fires, flooding, 
earthquakes and cyber-attacks may occur. It is not always possible to fully insure against such risks. Capstone 
currently  does  not  have  insurance  against  all  risks  and  may  decide  to  or  become  required  to  accept  higher 
deductibles or self-insure and not to take out insurance against certain risks as a result of high premiums or for 
other  reasons.  Further,  insurance  against  certain  risks,  including  but  not  limited  to  those  related  to  certain 
environmental matters, is generally not available to Capstone or to other companies within the mining industry. 
Losses from these events may cause Capstone to incur significant costs that could have a material adverse effect 
on Capstone’s business, financial condition, results of operation and prospects.  

Our operations will be adversely affected if we fail to maintain satisfactory labour relations.  

Our workforce is not unionized with the exception of approximately 371 of the hourly employees at the Pinto Valley 
Mine which are represented by six unions, governed by one collective bargaining agreement negotiated by the 
United Steelworkers Union which was renewed on May 30, 2018. Additional groups of non-union employees may 
seek  union  representation  in  the  future.  Further,  relations  with  employees  may  be  affected  by  changes  in  the 
scheme of labour relations that may be introduced by the relevant governmental authorities in jurisdictions where 
Capstone conducts business. Changes in such legislation or otherwise in our relationship with our employees may 
result in higher ongoing labour costs, employee turnover, strikes, lockouts or other work stoppages, any of which 
could have a material adverse effect on our business, results of operations and financial condition.  

48 

 
Increased energy prices could adversely affect Capstone’s results of operations and financial condition.  

Mining operations and facilities are intensive users of electricity and carbon-based fuels. Energy prices can be 
affected by numerous factors beyond our control, including global and regional supply and demand, political and 
economic conditions, and applicable regulatory regimes. The prices of various sources of energy may increase 
significantly from current levels. An increase in energy prices for which Capstone is not hedged could materially 
adversely affect our results of operations and financial condition.  

We may not be able to compete successfully with other mining companies.  

The  mining  industry  is  competitive  in  all  of  its  phases.  Capstone  faces  strong  competition  from  other  mining 
companies in connection  with the  acquisition of properties  producing or capable of producing metals. Many of 
these  companies  have  greater  liquidity,  greater  access  to  credit  and  other  financial  resources,  newer  or  more 
efficient  equipment,  lower  cost  structures,  more  effective  risk  management  policies  and  procedures  and/or  a 
greater ability than Capstone to withstand losses. Our competitors may be able to respond more quickly to new 
laws or regulations or emerging technologies or devote greater resources to the expansion or efficiency of their 
operations than we can. In addition, current and potential competitors may make strategic acquisitions or establish 
cooperative relationships amongst themselves or with third parties. Accordingly, it is possible that new competitors 
or alliances amongst current and new competitors may emerge and gain significant market share to our detriment. 
Capstone  may  also  encounter  increasing  competition  from  other  mining  companies  in  our  efforts  to  hire 
experienced  mining  professionals.  Increased  competition  could  adversely  affect  Capstone’s  ability  to  attract 
necessary  capital  funding,  to  acquire  it  on  acceptable  terms,  or  to  acquire  suitable  producing  properties  or 
prospects for mineral exploration in the future. As a result of this competition, we may not be able to compete 
successfully against current and future competitors, and any failure to do so could have a material adverse effect 
on our business, financial condition, results of operations and prospects. Further, Capstone may become a target 
for a corporate takeover or may decide to engage in a strategic merger. Such activities may create uncertainty 
among shareholders and markets and therefore influence share prices. 

Capstone may experience difficulties with Capstone’s joint venture partners.  

Capstone  currently  operates  the  Santo  Domingo  Project  through  a  joint  ownership  arrangement  with  Korea 
Resources Corporate (KORES) and may in the future enter into additional joint ownership arrangements with other 
partners. Capstone is subject to the risks normally associated with the conduct of joint ownership arrangements, 
which include disagreements with Capstone’s partners on how to develop, operate and finance Capstone’s joint 
ownership  activities,  including  future  acquisitions  or  the  Santo  Domingo  Project,  and  possible  disputes  with 
Capstone’s  partners  regarding  joint  ownership  arrangement  matters.  These  disagreements  and  disputes  may 
have an adverse effect on Capstone’s ability to successfully pursue joint ownership arrangements, including the 
development  of  the  Santo  Domingo  Project,  which  could  affect  our  business,  financial  condition,  results  of 
operation and prospects.  

Capstone acquired the Pinto Valley Mine on an “as is where is” basis, provided indemnities to BHP Copper 
and has limited recourse against BHP Copper with respect to many potential liabilities related to the Pinto 
Valley Mine.  

The Pinto Valley Mine was acquired on an “as is where is” basis with limited representations and warranties. In 
addition, Capstone has provided indemnities to  BHP  Copper with respect to certain liabilities  and have  limited 
recourse against BHP Copper with respect to many potential liabilities related to the Pinto Valley Mine. As a result, 
the acquisition of mineral properties, such as the Pinto Valley Mine, may subject Capstone to unforeseen liabilities, 
including environmental liabilities.  

Capstone may experience cybersecurity threats  

We rely on secure and adequate operations of information technology systems in the conduct of our operations. 
Access to and security of the information technology systems are critical to our operations. To our knowledge, we 
have not experienced any material losses relating to disruptions to our information technology systems. We have 
enhanced and implemented ongoing policies, controls and practices to manage and safeguard Capstone and our 

49 

 
stakeholders from internal and external cybersecurity threats and to comply with changing legal requirements and 
industry practice. Given that cyber risks cannot  be fully mitigated and the  evolving nature  of these threats, we 
cannot assure that our information technology systems are fully protected from cybercrime or that the systems will 
not  be  inadvertently  compromised  or  are  without  failures  or  defects.  Disruptions  to  our  information  technology 
systems, including, without limitation, security breaches, power loss, theft, computer viruses, cyber-attacks, natural 
disasters, and non-compliance by third party service providers and inadequate levels of cybersecurity expertise 
and  safeguards  of  third  party  information  technology  service  providers,  may  adversely  affect  the  operations  of 
Capstone  as  well  as  present  significant  costs  and  risks  including,  without  limitation,  loss  or  disclosure  of 
confidential,  proprietary,  personal  or  sensitive  information  and  third  party  data,  material  adverse  effect  on  our 
financial  performance,  compliance  with  our  contractual  obligations,  compliance  with  applicable  laws,  damaged 
reputation, remediation costs, potential litigation, regulatory enforcement proceedings and heightened regulatory 
scrutiny.  

Reputational risk  

Capstone is subject to public scrutiny and negative publicity which may impact our public image and reputation 
and ultimately impact our social license to operate. Our reputation can be damaged by the actual or perceived 
occurrence of any number of events or societal trends.  

Legal proceedings  

From  time  to  time,  Capstone  is  involved  in  routine  legal  matters,  including  but  not  limited  to,  regulatory 
investigations, claims, lawsuits, contract disputes and other proceedings in the ordinary course of our business. 
There can be no assurances that these matters will not have a material effect on our business. 

5 – DIVIDENDS AND DISTRIBUTIONS 

We have not declared or paid any dividends or distributions on our common shares in the last three financial years 
and have no present intention of doing so, as we anticipate that all available funds will be invested to finance the 
growth of our business.

approximately 3% of the issued and outstanding common shares of Capstone. 

8.3  

Cease Trade Orders, Bankruptcies, Penalties or Sanctions 

To the knowledge of Capstone, after reasonable enquiry, no director or officer of Capstone is, as at the date of 
this Annual Information Form, or was within 10 years before the date of this Annual Information Form, a director, 
chief executive officer or chief financial officer of any company (including Capstone) that:  

a.  was subject to a cease trade order, an order similar to a cease trade order, or an order that denied the 
relevant company access to any exemption under securities legislation, that was in effect for a period for 
more than 30 consecutive days (together, an “order”), that was issued while the director or officer was 
acting in the capacity as director, chief executive officer or chief financial officer; or 

53 

 
b.  was subject to an order that was issued after the director or officer ceased to be a director, chief executive 
officer or chief financial officer and which resulted from an event that occurred while that person was acting 
in the capacity as director, chief executive officer or chief financial officer, except: 

Mr. Peter Meredith served as a director of Ivanhoe Energy Inc. (“Ivanhoe Energy”) from December 2007 
to December 2014. On February 20, 2015, Ivanhoe Energy filed a Notice of Intention to Make a Proposal 
under subsection 50.4(1) of the Bankruptcy and Insolvency Act (Canada). Cease trade orders were issued 
against  Ivanhoe  Energy  in  Alberta  (July  15,  2015),  Quebec  (May  7,  2015),  Manitoba  (May  6,  2015), 
Ontario (May 4, 2015) and British Columbia (April 14, 2015) in respect of the company failing to file its 
audited financial statements and annual management’s discussion and analysis, annual information form 
and certification of annual filings for the year ended December 31, 2014. The foregoing cease trade orders 
remain  in  effect.  On  June  2,  2015,  having  failed  to  file  a  proposal,  Ivanhoe  Energy  was  assigned  into 
bankruptcy. Ivanhoe Energy dissolved on May 16, 2017.  

To  the  knowledge  of  Capstone,  after  reasonable  enquiry,  no  director  or  officer  of  Capstone,  or  a  shareholder 
holding a sufficient number of securities of Capstone to affect materially the control of Capstone:  

a. 

is as at the date of this Annual Information Form, or has been within the 10 years before the date of this 
Annual Information Form, a director or officer of any company that, while that person was acting in that 
capacity, or within a year of that person was acting in that capacity, became bankrupt, made a proposal 
under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, 
arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to 
hold its assets; or  

b.  has,  within  the  10  years  before  the  date  of  this  Annual  Information  Form,  become  bankrupt,  made  a 
proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any 
proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee 
appointed to hold the assets of the director, executive officer or shareholder. 

To  the  knowledge  of  Capstone,  after  reasonable  enquiry,  no  director  or  officer  of  Capstone,  or  a  shareholder 
holding a sufficient number of securities of Capstone to affect materially the control of Capstone has been subject 
to  any  penalties  or  sanctions  imposed  by  a  court  relating  to  securities  legislation  or  by  a  securities  regulatory 
authority or has entered into a settlement agreement with a securities regulatory authority, or any other penalties 
or  sanctions  imposed  by  a  court  or  regulatory  body  that  would  likely  be  considered  important  to  a  reasonable 
investor in making an investment decision. 

8.4 

Conflicts of Interest 

Certain  of  our  directors  and  officers  serve  or  may  agree  to  serve  as  directors  or  officers  of  other  reporting 
companies, including public companies as noted in 8.1 above, or have significant shareholdings in other reporting 
companies and, to the extent that such other companies may participate in ventures in which we may participate, 
our directors may have a conflict of  interest in negotiating and concluding  terms respecting the extent of such 
participation. In the event that such a conflict of interest arises at a meeting of our directors, a director who has a 
conflict abstains from voting for or against the approval of such participation or such terms and such director will 
not  participate  in  negotiating  and  concluding  terms  of  any  proposed  transaction.  From  time  to  time,  several 
companies may participate in the acquisition, exploration and development of natural resource properties thereby 
allowing for their participation in larger programs, permitting  involvement in a greater number of programs  and 
reducing financial exposure in respect of any one program. It may also occur that a particular company will assign 
all or a portion of its interest in a particular program to another of these companies due to the financial position of 
the company making the assignment. Under the laws of the Province of British Columbia, the directors of Capstone 
are required to act honestly, in good faith and in the best interests of Capstone. In determining whether or not we 
will  participate  in  a  particular  program  and  the  interest  therein  to  be  acquired  by  it,  the  directors  will  primarily 
consider the degree of risk to which we may be exposed and our financial position at that time. See also  Risk 
Factors.

Audit Committee Oversight 

At no time since the commencement of our most recently completed financial year was a recommendation of the 
Committee to nominate or compensate an external auditor not adopted by the Board of Directors. 

9.4 

Pre-Approval Policies and Procedures 

The Audit Committee pre-approves all non-audit services provided by our external auditor and has established 
policies  and  procedures  accordingly.  When  a  new  service  is  proposed  by  Capstone’s  external  auditor, 
management confirms with the audit engagement partner that there is no independence concern related to the 

55 

 
proposed service. Once it is confirmed by the audit engagement partner and the Chair of the Audit Committee that 
the proposed service(s) would not impair the auditor’s independence, the matter is raised to the Audit Committee 
for approval before management proceeds with engaging the external auditor to perform the proposed service(s). 

9.5

10 – LEGAL PROCEEDINGS AND REGULATORY ACTIONS 

Legal Proceedings 

Capstone  was  not  subject  to  any  material  legal  proceedings  throughout  the  recently  completed  financial  year. 
Capstone is, from time to time, involved in legal claims, proceedings and complaints arising in the ordinary course 
of business. While the outcome of these legal proceedings cannot be predicted with certainty, we believe that any 
adverse  decision  in  such  proceedings  or  complaints  will  not  have  a  material  adverse  effect  on  the  financial 
condition  or  operations  of  Capstone.  The  directors  and  management  know  of  no  contemplated  or  pending 
proceedings against anyone that might materially adversely affect our financial condition or results of operations. 

Regulatory Actions 

Capstone is not subject to: 

•  any penalties or sanctions  imposed against Capstone by a court relating to securities  legislation or by  a 

securities regulatory authority during the financial year ended December 31, 2019; or 

•  any other penalties or sanctions imposed by a court or regulatory body against Capstone that would likely 

be considered important to a reasonable investor in making an investment decision; or 

•  settlement  agreements  Capstone  entered  into  before  a  court  relating  to  securities  legislation  or  with  a 

securities regulatory authority during the financial year ended December 31, 2019. 

11 – INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS 

Except as otherwise disclosed herein, no director, executive officer or principal shareholder of Capstone, or any 
associate or affiliate of the foregoing, have had any material interest, direct or indirect, in any transaction within 
the three most recently completed financial years or during the current financial year prior to the date of this Annual 
Information Form that has materially affected or will materially affect Capstone.
