cut-off grade

deposit

Select Mining Definitions

A  type  of  intrusive  or  extrusive  igneous  rock  defined  by  mineralogic  composition  consisting  of  greater  than  50%
carbonate minerals.

The  grade  (i.e.,  the  concentration  of  metal  or  mineral  in  rock)  that  determines  the  destination  of  the  material  during
mining. For purposes of establishing “prospects of economic extraction,” the cut-off grade is the grade that distinguishes
material deemed to have no economic value (it will not be mined in underground mining or if mined in surface mining, its
destination will be the waste dump) from material deemed to have economic value (its ultimate destination during mining
will be a processing facility). Other terms used in similar fashion as cut-off grade include net smelter return, pay limit,
and break-even stripping ratio.

A mineralized body which has been physically delineated by sufficient drilling, trenching, and/or underground work, and
found  to  contain  a  sufficient  average  grade  of  metal  or  metals  to  warrant  further  exploration  and/or  development
expenditures.  Such  a  deposit  does  not  qualify  as  a  commercially  mineable  ore  body  or  as  containing  reserves  or  ore,
unless final legal, technical, and economic factors are resolved.

development stage issuer

An issuer that is engaged in the preparation of mineral reserves for extraction on at least one material property

development stage property

A property that has mineral reserves disclosed, pursuant to Regulation S-K 1300, but no material extraction

diamond drilling

dysprosium or Dy

dysprosium oxide

economically viable

feasibility study

A type of rotary drilling in which diamond bits are used as the rock-cutting tool to produce a recoverable drill core sample
of rock for observation and analysis

The chemical element with an atomic number 66. It is a rare-earth element in the lanthanide series.

The chemical compound composed of dysprosium and oxygen with the formula Dy2O3

When  used  in  the  context  of  mineral  reserve  determination,  means  that  the  qualified  person  has  determined,  using  a
discounted  cash  flow  analysis,  or  has  otherwise  analytically  determined,  that  extraction  of  the  mineral  reserve  is
economically viable under reasonable investment and market assumptions

A comprehensive technical and economic study of the selected development option for a mineral project, which includes
detailed  assessments  of  all  applicable  modifying  factors,  as  defined  under  S-K  1300,  together  with  any  other  relevant
operational  factors,  and  detailed  financial  analysis  that  are  necessary  to  demonstrate,  at  the  time  of  reporting,  that
extraction is economically viable. The results of the study may serve as the basis for a final decision by a proponent or
financial institution to proceed with, or finance, the development of the project.

(1) A feasibility study is more comprehensive, and with a higher degree of accuracy, than a pre-feasibility study. It must
contain mining, infrastructure, and process designs completed with sufficient rigor to serve as the basis for an investment
decision or to support project financing.

(2) The  confidence  level  in  the  results  of  a  feasibility  study  is  higher  than  the  confidence  level  in  the  results  of  a  pre-
feasibility study. Terms such as full, final,

i

comprehensive, bankable, or definitive feasibility study are equivalent to feasibility study.

indicated mineral resource

inferred mineral resource

That part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological
evidence  and  sampling. The  level  of  geological  certainty  associated  with  an  indicated  mineral  resource  is  sufficient  to
allow  a  qualified  person  to  apply  modifying  factors  in  sufficient  detail  to  support  mine  planning  and  evaluation  of  the
economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of
confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral
reserve.

That part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological
evidence  and  sampling. The  level  of  geological  uncertainty  associated  with  an  inferred  mineral  resource  is  too  high  to
apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful
for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence
of  all  mineral  resources,  which  prevents  the  application  of  the  modifying  factors  in  a  manner  useful  for  evaluation  of
economic  viability,  an  inferred  mineral  resource  may  not  be  considered  when  assessing  the  economic  viability  of  a
mining project, and may not be converted to a mineral reserve.

LoM

Life of Mine, the period from the beginning of construction to the end of mine life

measured mineral resource

mineral reserve

mineral resource

modifying factors

That part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological
evidence  and  sampling.  The  level  of  geological  certainty  associated  with  a  measured  mineral  resource  is  sufficient  to
allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine
planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher
level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a
measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

An  estimate  of  tonnage  and  grade  or  quality  of  indicated  and  measured  mineral  resources  that,  in  the  opinion  of  the
qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable
part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may
occur when the material is mined or extracted.

A concentration or occurrence of 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 economic extraction. A mineral resource is a reasonable estimate of
mineralization,  taking  into  account  relevant  factors  such  as  cut-off  grade,  likely  mining  dimensions,  location  or
continuity,  that,  with  the  assumed  and  justifiable  technical  and  economic  conditions,  is  likely  to,  in  whole  or  in  part,
become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

The factors that a qualified person must apply to indicated and measured mineral resources and then evaluate in order to
establish  the  economic  viability  of  mineral  reserves. A  qualified  person  must  apply  and  evaluate  modifying  factors  to
convert

measured  and  indicated  mineral  resources  to  proven  and  probable  mineral  reserves.  These  factors  include,  but  are  not
restricted  to:  mining;  processing;  metallurgical;  infrastructure;  economic;  marketing;  legal;  environmental  compliance;
plans,  negotiations,  or  agreements  with  local  individuals  or  groups;  and  governmental  factors.  The  number,  type  and
specific characteristics of the modifying factors applied will necessarily be a function of and depend upon the mineral,
mine, property, or project.

The element niobium (atomic number 41), a transition metal primarily used in the production of high-strength, low-alloy
steel

Niobium pentoxide, a commercial form of refined niobium

The chemical compound composed of neodymium and oxygen with the formula Nd2O3

qualified person

An individual who is:

(1)   A mineral industry professional with at least five years of relevant experience in the type of mineralization and type
of  deposit  under  consideration  and  in  the  specific  type  of  activity  that  person  is  undertaking  on  behalf  of  the
registrant; and

(2)   An eligible member or licensee in good standing of a recognized professional organization at the time the technical

report is prepared. For an organization to be a recognized professional organization, it must:

(i)  Be either:

(A)  An organization recognized within the mining industry as a reputable professional association; or

(B)  A board authorized by Unites States federal, state, or foreign statute to regulate professionals in the mining,

geoscience, or related field;

(ii)   Admit eligible members primarily on the basis of their academic qualifications and experience;

(iii)    Establish and require compliance with professional standards of competence and ethics;

(iv)    Require or encourage continuing professional development;

(v)     Have and apply disciplinary powers, including the power to suspend or expel a member regardless of where the

member practices or resides; and

relevant experience

(vi)    Provide a public list of members in good standing.

A group of 15 elements referred to as the lanthanide series in the periodic table of elements. Scandium and yttrium, while
not true REEs, are also included in this categorization because they exhibit similar properties to the lanthanides and are
found  in  the  same  ore  bodies.  Individual  mineral  deposits  may  not  contain  all  REEs  in  economically  recoverable
quantities.

Commercial  rare  earth  products  currently  being  examined  for  production  by  the  Company,  including  neodymium-
praseodymium  oxide  (sometimes  referred  to  as  didymium  oxide),  dysprosium  oxide,  and  terbium  oxide. These  are  the
primary rare earths compounds used to manufacture the world’s most powerful permanent magnets.

For purposes of determining whether a party is a qualified person, that the party has experience in the specific type of
activity that the person is undertaking on behalf of the registrant. If the qualified person is preparing or supervising the
preparation  of  a  technical  report  concerning  exploration  results,  the  relevant  experience  must  be  in  exploration.  If  the
qualified person is estimating, or supervising the estimation of mineral resources, the relevant experience must be in the
estimation,  assessment  and  evaluation  of  mineral  resources  and  associated  technical  and  economic  factors  likely  to
influence  the  prospect  of  economic  extraction.  If  the  qualified  person  is  estimating,  or  supervising  the  estimation  of
mineral  reserves,  the  relevant  experience  must  be  in  engineering  and  other  disciplines  required  for  the  estimation,
assessment, evaluation, and economic extraction of mineral reserves.

(1)   Relevant experience also means, for purposes of determining whether a party is a qualified person, that the party has
experience evaluating the specific type of mineral deposit under consideration (e.g., coal, metal, base metal, industrial
mineral,  or  mineral  brine).  The  type  of  experience  necessary  to  qualify  as  relevant  is  a  facts  and  circumstances
determination.  For  example,  experience  in  a  high-nugget,  vein-type  mineralization  such  as  tin  or  tungsten  would
likely be relevant experience for estimating mineral resources for vein-gold mineralization, whereas experience in a
low grade disseminated gold deposit likely would not be relevant.

Note 1 to Paragraph (1) of the Definition of Relevant Experience: It is not always necessary for a person to have five
years’  experience  in  each  and  every  type  of  deposit  in  order  to  be  an  eligible  qualified  person  if  that  person  has
relevant experience in similar deposit types. For example, a person with 20 years’ experience in estimating mineral
resources  for  a  variety  of  metalliferous  hard-rock  deposit  types  may  not  require  as  much  as  five  years  of  specific
experience in porphyry-copper deposits to act as a qualified person. Relevant experience in the other deposit types
could count towards the experience in relation to porphyry-copper deposits.

(2)      For  a  qualified  person  providing  a  technical  report  for  exploration  results  or  mineral  resource  estimates,  relevant
experience  also  requires,  in  addition  to  experience  in  the  type  of  mineralization,  sufficient  experience  with  the
sampling and analytical techniques, as well as extraction and processing techniques, relevant to the mineral deposit
under  consideration.  Sufficient  experience  means  that  level  of  experience  necessary  to  be  able  to  identify,  with
substantial confidence, problems that could affect the reliability of data and issues associated with processing.

iv 

 
 
 
 
 
 
 
(3)      For  a  qualified  person  applying  the  modifying  factors,  as  defined  by  this  section,  to  convert  mineral  resources  to

mineral reserves, relevant experience also requires:

(i)        Sufficient  knowledge  and  experience  in  the  application  of  these  factors  to  the  mineral  deposit  under

consideration; and

(ii)    Experience with the geology, geostatistics, mining, extraction, and processing that is applicable to the type of

mineral and mining under consideration.

Mineral Reserves and Resources

Information  concerning  our  mining  property  in  this Annual  Report  on  Form  10-K  has  been  prepared  in  accordance  with  the  requirements  of  S-K  1300,  which  first
became applicable to us for the fiscal year ended June 30, 2022. All mineral resource and mineral reserve estimates included in this Annual Report on Form 10-K have been
prepared in accordance with S-K 1300. Previously, we prepared our estimates of mineral resources and mineral reserves following only National Instrument 43-101 of the
Canadian Securities Administrators entitled “Standards of Disclosure for Mineral Projects” (“NI 43-101”) and the Canadian Institute of Mining and Metallurgy (“CIM”)
“Definition Standards – For Mineral Resources and Mineral Reserves, May 10, 2014.” The CIM-compliant NI 43-101 technical report (the “NI 43-101 Elk Creek Technical
Report”) for the Company’s niobium, scandium, and titanium project (the “Elk Creek Project”) and S-K 1300 Elk Creek Technical Report Summary, filed as Exhibit 96.1 to
the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2022 and incorporated by reference into this Annual Report on Form 10-K, are based on a
feasibility study prepared by qualified persons (the “2022 Elk Creek Feasibility Study”) and are substantively identical to one another except for internal references to the
regulations under which the report is made, and certain organizational differences. In addition, S-K 1300 requires us to disclose our mineral resources, in addition to our
mineral reserves, as of the end of our most recently completed fiscal year. You are cautioned that mineral resources are subject to further exploration and development and
are subject to additional risks and no assurance can be given that they will eventually convert to future reserves. Inferred resources, in particular, have a great amount of
uncertainty  as  to  their  existence  and  their  economic  and  legal  feasibility.  Investors  are  cautioned  not  to  assume  that  any  part  or  all  of  the  inferred  resource  exists  or  is
economically or legally mineable. See Item 1A, Risk Factors.

Currency and Exchange Rates

All  dollar  amounts  in  this Annual  Report  on  Form  10-K  are  expressed  in  United  States  (“U.S.”)  dollars  unless  otherwise  indicated.  The  Company’s  accounts  are
maintained  in  U.S.  dollars  and  the  Company’s  consolidated  financial  statements  are  prepared  in  accordance  with  U.S.  generally  accepted  accounting  principles  (“U.S.
GAAP”). Some of the Company’s significant agreements, as well as certain vendors, use Canadian dollars. As used herein, “C$” represents Canadian dollars. 

The  following  table  sets  forth  the  rate  of  exchange  for  the  Canadian  dollar,  expressed  in  U.S.  dollars  in  effect  at  the  end  of  the  periods  indicated,  the  average  of

“Kingston Resources Ltd.” On June 29, 2001, we changed our name to “Butler Developments Corp.” On February 12, 2009, we changed our name to “Butler Resource
Corp.” On March 4, 2010, we changed our name to “Quantum Rare Earth Developments Corp.” On March 4, 2013, we changed our name to “NioCorp Developments Ltd.”

NioCorp is a reporting issuer in British Columbia, Alberta, Saskatchewan, Ontario, and New Brunswick. Our registered and records office is located at 595 Burrard
Street, Suite 2600, Vancouver, British Columbia V7X 1L3 (ATTN: Blake, Cassels & Graydon LLP). Our principal executive office is located at 7000 South Yosemite Street,
Suite 115, Centennial, Colorado 80112.

Historical Development of the Business

During 2009 and 2010, the Company commenced mineral exploration activities in the Elk Creek, Nebraska area, including negotiations with local landowners for land
access agreements. The acquisition of the carbonatite property located in Southeast Nebraska, USA (the “Elk Creek Property”) was closed in December 2010 and involved
the  purchase  of  all  of  the  issued  and  outstanding  common  shares  of  0859404  BC  Ltd.,  a  private  British  Columbia  company,  which  in  turn  held  100%  of  the  issued  and
outstanding shares of Elk Creek Resources Corp., a Nebraska corporation (“Old ECRC”), and was signatory to the option agreements covering the Elk Creek Property area.
A new Canadian company, 0886338 BC Ltd. was formed to merge with 0859404 BC Ltd., and this merged entity was subsequently amalgamated into 0896800 B.C. Ltd., a
private British Columbia company and a wholly owned subsidiary of the Company (“0896800”).

The Company commenced a field exploration program in 2011, which included verification of previous work which was completed on the Elk Creek Property in the
1970s and 1980s, re-assaying of historic drill core, an airborne geophysical survey and the completion of five new diamond drillholes. The available data for the Elk Creek
Property was compiled into an updated NI 43-101 resource estimate for the Elk Creek Project, which was issued in April 2012. Additional drilling and NI 43-101 technical
reports, including resource updates and preliminary economic assessments, were completed and issued by the Company in 2014 and 2015.

During  fiscal  years  2016  and  2017,  the  Company  focused  on  feasibility  study  development,  and  on  June  30,  2017,  we  announced  the  completion  of  a  NI  43-101
technical  report  for  the  Elk  Creek  Project  (the  “2017  NI  43-101  Elk  Creek  Technical  Report”).  In  connection  with  a  review  by  the  Ontario  Securities  and  Exchange
Commission, on December 15, 2017, the Company filed a revised 2017 NI 43-101 Elk Creek Technical Report. This revised report contained no changes to any previously
reported numbers or forecasted economic returns of the Elk Creek Project from those contained in the originally filed 2017 NI 43-101 Elk Creek Technical Report.

During fiscal year 2019, we received a new mine design based on detailed underground engineering conducted by The Nordmin Group of Companies (“Nordmin”)
along  with  an  updated  mineral  resource  and  mineral  reserve.  On  April  16,  2019,  we  announced  the  results  of  the  updated  underground  mine  design  and  supporting
infrastructure, the results of an update to the Elk Creek Project, and the filing of an NI 43-101 technical report for the Elk Creek Project based on the new mine design.
During fiscal year 2020, the Company focused efforts on advancing detailed engineering of the surface and underground facilities and negotiating the follow-on contracts
associated with the planned construction of the surface and underground features of the project, as well as obtaining a State of Nebraska permit which describes all the
prospective air emissions from a facility (the “Air Permit”). The Air Permit required the completion of an air quality model that demonstrates compliance with the U.S.
National Ambient Air Quality Standards limits on atmospheric concentration of six pollutants that cause smog, acid rain, and other health hazards, as established by the EPA
(“NAAQS”). The final Air Permit was issued by the State of Nebraska on June 2, 2020, for the Elk Creek Project.

During fiscal year 2021, we obtained funding which allowed us to purchase land and mineral rights at the Elk Creek Property and continue early project execution
activities. With the acquisition of the land and mineral rights, the Company now owns the surface land on which the Elk Creek Project’s mine infrastructure and supporting
operations will be located once sufficient project financing is obtained, along with ownership of the mineral rights to more than 90% of the Elk Creek Project’s mineral
resources and mineral reserves.

During fiscal year 2022, we focused efforts towards refining our Elk Creek Project mineral resource and mineral reserve estimates with respect to REEs. This work
included additional assays of historical drill core to fill data gaps in the existing resource database and re-modeling. Based on this re-interpretation of the geologic data, an
update to the mine plan was also completed. Based on this work, we issued the 2022 NI 43-101 Elk Creek Technical Report on June 28, 2022, and filed the S-K 1300 Elk
Creek Technical Report Summary as an exhibit to our Annual Report on Form 10-K for the year ended June 30, 2022.

During fiscal year 2022, we also advanced our efforts to optimize our process design to contemplate the recovery and production of REEs, including completion of
bench and pilot scale testing on elements of the current metallurgical flowsheet. This work illustrated that NioCorp could recover and produce high purity, fully separated
magnetic rare earth products, such as neodymium-praseodymium oxide, dysprosium oxide, and terbium oxide in addition to the niobium, scandium, and titanium products
already planned for production by the Company, once Project financing is secured and additional work has been completed on the technical and economic feasibility of
adding REEs to the Elk Creek Project’s existing planned product suite. Following the success of this testing, the Company advanced the construction of a demonstration-
scale processing plant located in Trois-Rivieres, Quebec built by the Company and L3 Process Development (“L3”) and operated by L3 (the “Demonstration Plant”).

During fiscal year 2023, we completed construction and operated the Demonstration Plant. The Demonstration Plant results showed higher recoveries for our primary
niobium product, much higher recoveries and a higher value titanium product in the form of titanium tetrachloride, and a high recovery rate for the three planned rare earth
oxides of consequence: neodymium/praseodymium oxide, dysprosium oxide and terbium oxide. In addition, we completed initial site preparation work at the Elk Creek
Project, which consisted of tree and brush clearing. A geotechnical investigation at the project site was also completed, which involved excavated test pits, geotechnical
borings and the installation of shallow groundwater piezometers. The geotechnical program generated valuable data for the firms that are working on the detailed design of
the facilities and infrastructure associated with the Elk Creek Project.

Information regarding the Elk Creek Project is discussed below under Item 2., “Properties.”

On March 17, 2023 (the “Closing Date”), the Company closed a series of transactions (the “GXII Transaction”) pursuant to the Business Combination Agreement, dated
as of September 25, 2022 (the “Business Combination Agreement”), by and among the Company, GX Acquisition Corp. II, a Delaware corporation (“GXII”), and Big Red
Merger Sub Ltd., a Delaware corporation and a direct, wholly owned subsidiary of the Company (“Merger Sub”). Pursuant to the Business Combination Agreement, the
GXII Transaction was accounted for as an equity raise

2

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
transaction in accordance with U.S. GAAP. At the Closing of the GXII Transaction (the “Closing”), the following transactions occurred:

  ● As  a  result  of  a  series  of  transactions,  including,  without  limitation,  the  mergers  of  Merger  Sub  and  Old  ECRC  with  and  into  GXII,  with  GXII  surviving  such
mergers, GXII became an indirect, majority-owned subsidiary of NioCorp and changed its name to “Elk Creek Resources Corp”, which we refer to as “ECRC”.

  ● As  the  parent  company  of  the  merged  entity,  NioCorp  issued  1,753,821  post-Reverse  Stock  Split  common  shares  of  the  Corporation  (the  “Common  Shares”)  in
exchange for all of the Class A shares of GXII issued and outstanding immediately prior to the Closing, including 83,770 Common Shares issued to BTIG, LLC in
exchange for Class A shares of GXII that it received as partial payment for advisory services.

  ● All of the Class B shares of GXII issued and outstanding immediately prior to the Closing (after giving effect to the surrender of certain Class B shares of GXII in
accordance with the Sponsor Support Agreement, dated September 25, 2022 (the “Sponsor Support Agreement”), among GX Sponsor II LLC (the “Sponsor”), GXII,
the Company, and the other persons party thereto, were converted into 7,957,404 shares of Class B common stock of GXII (now known as ECRC) as the surviving
entity  of  the  mergers  that  occurred  on  the  Closing  Date  as  part  of  the  GXII Transaction.  Pursuant  to  the  Business  Combination Agreement,  the  Sponsor  Support
Agreement and the Exchange Agreement, dated as of March 17, 2023 (as amended, supplemented or otherwise modified, the “Exchange Agreement”), by and among
NioCorp, ECRC and the Sponsor, after the Closing, the shares of Class B common stock of ECRC are exchangeable into Common Shares on a one-for-one basis,
subject to certain equitable adjustments, under certain conditions. Of the issued and outstanding shares of Class B common stock of ECRC, 4,565,808 shares (the
“Vested Shares”) were vested as of the Closing Date and are exchangeable at any time, and from time to time, until the tenth anniversary of the Closing Date (the
“Ten-Year Anniversary”) and 3,391,596 shares (the “Earnout Shares”) are exchangeable until the Ten-Year Anniversary, subject to certain vesting conditions. See
Note 10 to the consolidated financial statements included in Part II, Item 8 hereof for additional information regarding the Class B common stock of ECRC.

  ● NioCorp assumed GXII’s obligations under the agreement governing the GXII share purchase warrants (the “GXII Warrants”) and issued an aggregate of 15,666,626
warrants (the “NioCorp Assumed Warrants”) to purchase up to an aggregate of 17,519,864 Common Shares. The NioCorp Assumed Warrants issued at the Closing
consisted of (a) 9,999,959 public NioCorp Assumed Warrants (the “Public Warrants”) that were issued in respect of the GXII Warrants that were publicly traded prior
to the Closing and (b) 5,666,667 NioCorp Assumed Warrants (the “Private Warrants”) that were issued to the Sponsor in respect of the GXII Warrants that it held
prior to the Closing, which NioCorp Assumed Warrants were subsequently distributed by the Sponsor to its members in connection with the Closing. See Note 11b to
the consolidated financial statements included in Part II, Item 8 hereof for additional information regarding the NioCorp Assumed Warrants.

On the Closing Date, the Company also effected a reverse stock split (the “Reverse Stock Split”) based on one (1) post-Reverse Stock Split Common Share for every
ten (10) pre-Reverse Stock Split Common Shares issued and outstanding effectuated by the Company on the Closing Date. Any fractional shares resulting from the Reverse
Stock Split were rounded down to the nearest whole Common Share.

As part of the GXII Transaction, on January 26, 2023, the Company entered into definitive agreements with respect to two separate financing packages with YA II PN,

Ltd., an investment fund managed by Yorkville Advisors Global, LP (“Yorkville”), including:

● A  Securities  Purchase  Agreement,  dated  January  26,  2023  (as  amended,  the  “Yorkville  Convertible  Debt  Financing  Agreement”),  between  the  Company  and
Yorkville,  under  which  the  Company  issued  to  Yorkville  unsecured  convertible  debentures  in  the  original  aggregate  principal  amount  of  $16.0  million  (the
“Convertible Debentures”) and Common Share purchase warrants, exercisable for up to 1,789,267 Common Shares for cash or, if at any time there is no effective
registration  statement  registering,  or  no  current  prospectus  available  for,  the  resale  of  the  underlying  Common  Shares,  on  a  cashless  basis,  at  the  option  of  the
holder, at a price per Common Share of approximately $8.9422, subject to adjustment to give effect to any stock dividend, stock split, reverse stock split or similar
transaction (the “Financing Warrants”), on the

Closing Date, for gross proceeds of $15.36 million (the “Yorkville Convertible Debt Facility Financing”); and. 

● A Standby Equity Purchase Agreement, dated January 26, 2023 (the “Yorkville Equity Facility Financing Agreement”), between the Company and Yorkville, under
which Yorkville agreed to purchase up to $65.0 million of Common Shares over the next three years, at NioCorp’s direction and subject to certain restrictions (the
“Yorkville Equity Facility Financing”).

These  financing  packages  are  further  discussed  below  under  “Management’s  Discussion  and Analysis  of  Financial  Condition  and  Results  of  Operations  –  Liquidity  and
Capital Resources – Financing Activities.”

The  transactions  contemplated  by  the  Business  Combination  Agreement,  including  the  GXII  Transaction,  the  Yorkville  Convertible  Debt  Facility  Financing,  the

Yorkville Equity Facility Financing, and the Reverse Stock Split are referred to, collectively, as the “Transactions.”

After  consideration  of  GXII  expenses  incurred  in  connection  with  the Transactions,  the  Company  acquired  net  cash  of  approximately  $2.2  million  and  assumed  net
liabilities of approximately $0.4 million. We also assumed Private Warrant liabilities and the Earnout Shares liability, which were initially recorded at their non-cash fair
market value of approximately $3.0 million and approximately $13.2 million, respectively. The Company incurred expenses related to the Transactions of approximately
$6.8 million, all of which were recorded as other operating expenses.

In addition, in connection with the Transactions, the Common Shares and the NioCorp Assumed Warrants were listed for trading on The Nasdaq Stock Market LLC
(“Nasdaq”). The Common Shares and the NioCorp Assumed Warrants began trading on the Nasdaq Global Market and the Nasdaq Capital Market, respectively, on March
21,  2023,  under  the  symbols  “NB”  and  “NIOBW,”  respectively. The  Common  Shares  continued  to  trade  on  the Toronto  Stock  Exchange  (the  “TSX”)  under  the  symbol
“NB,” and began trading on the Nasdaq on a post-Reverse Stock Split basis on March 21, 2023. The Common Shares ceased being quoted on the U.S. over the counter
markets in connection with the commencement of trading on the Nasdaq Global Market.

Business Operations

NioCorp is a mineral exploration company engaged in the acquisition, exploration, and development of mineral properties. NioCorp, through ECRC, is developing a
superalloy materials project that, if and when developed, will produce niobium, scandium, titanium, and potentially, rare earth products. Known as the “Elk Creek Project,”
it is located near Elk Creek, Nebraska, in the southeast portion of the state.

● Niobium is used to produce various superalloys that are extensively used in high performance aircraft and jet turbines. It also is used in high-strength, low-alloy
steel, a stronger steel used in automobiles, bridges, structural systems, buildings, pipelines, and other applications that generally enables those applications to be
stronger and lighter in mass. This “lightweighting” benefit often results in environmental benefits, including reduced fuel consumption and material usage, which
can result in fewer air emissions.

● Scandium can be combined with aluminum to make super-high-performance alloys with increased strength and improved corrosion resistance. Scandium also is a

critical component of advanced solid oxide fuel cells, an environmentally preferred technology for high-reliability, distributed electricity generation.

● Titanium  is  a  component  of  various  superalloys  and  other  applications  that  are  used  for  aerospace  applications,  weapons  systems,  protective  armor,  medical

implants and many others. It also is used in pigments for paper, paint, and plastics.

During fiscal year 2023, the Company completed work at its Demonstration Plant that confirmed metallurgical recoveries for magnetic rare earth products. Additional

work is needed to modify the design of the proposed surface plant to make these products and to determine the capital cost of these modifications.

Our primary business strategy is to advance our Elk Creek Project to commercial production. We are focused on obtaining additional funds to carry out our near-term

planned work programs associated with securing the project financing necessary to complete detailed design, development, and construction of the Elk Creek Project.

Competitive Business Conditions

There is significant competition within the minerals industry to discover and acquire mineral properties considered to have commercial potential. We compete for the
opportunity  to  participate  in  promising  exploration  projects  with  other  entities.  In  addition,  we  compete  with  others  in  efforts  to  obtain  financing  to  acquire  and  explore
mineral properties, acquire and utilize mineral exploration equipment, and hire qualified mineral exploration personnel. We may compete with other mining companies for
mining claims in regions adjacent to our existing claims, or in other parts of the world should we dedicate resources to doing so in the future. These companies may be better
capitalized than us and we may have difficulty in expanding our holdings through the staking or acquisition of additional mining claims or other mineral tenures.

In competing for qualified mineral exploration personnel, we may be required to pay compensation or benefits relatively higher than those paid in the past, and the
availability of qualified personnel may be limited in high-demand mining periods, such as was the case in past years when the price of gold and other metals was higher than
it is now.

Cycles

The mining business is subject to mineral price cycles. The marketability of minerals and mineral concentrates is also affected by worldwide economic cycles. At the
present  time,  strong  demand  for  some  minerals  in  many  countries  is  lifting  commodity  prices,  although  it  is  difficult  to  assess  how  long  such  trends  may  continue.
Fluctuations in supply and demand in various regions throughout the world are common.

The following table sets forth commodity prices for the last five calendar years for the ferroniobium, scandium trioxide and titanium dioxide products the Company
anticipates extracting from its Elk Creek Project. These pricing surveys may not be representative of the pricing that the Company anticipates achieving for its products once
commercial production begins from its Elk Creek Project.

Based  on  results  of  the  Company’s  Demonstration  Plant,  a  higher  value  titanium  tetrachloride  product  can  be  produced  with  a  substantially  higher  metallurgical
recovery than TiO2. The Company is in the process of completing feasibility level cost estimates to replace the previous TiO2 production equipment with new equipment
that would produce titanium tetrachloride.

As NioCorp is a development stage issuer and has not yet generated any revenue from the operation of the Elk Creek Project, it is not currently significantly affected by
changes in commodity demand and prices, except to the extent that same impact the availability of capital for mineral exploration and development projects. As it does not
carry on production activities, NioCorp’s ability to fund ongoing exploration is affected by the availability of financing, which is, in turn, affected by the strength of the
economy and other general economic factors.

Economic Dependence

Other than land and mineral right option agreements and agreements between NioCorp and third parties for the purchase and sale of products to be produced from the
Elk Creek Project (“offtake agreements”), NioCorp’s business is not substantially dependent on any contract such as a contract to sell the major part of its product or services
or to purchase the major part of its requirements for goods, services or its raw materials, or any franchise or license or other agreement to use a patent, formula, trade secret,
process or trade name upon which its business depends.

Government Regulation

The exploration and development of a mining prospect is subject to regulation by a number of federal and state government authorities. These include the United States
Environmental  Protection  Agency  (the  “EPA”)  and  the  United  States  Army  Corps  of  Engineers  (the  “USACE”)  as  well  as  the  various  state  and  local  environmental
protection agencies. The regulations address many environmental issues relating to air, soil, and water contamination, and apply to many mining related activities including
exploration, mine construction, mineral extraction, ore milling, water use, waste disposal, and use of toxic substances. In addition, we are subject to regulations relating to
labor standards, occupational health and safety, mine safety, general land use, export of minerals, taxation, data protection, and data security. Many of the regulations require
permits  or  licenses  to  be  obtained,  the  absence  of  which  and/or  inability  to  obtain  such  permits  or  licenses  will  adversely  affect  our  ability  to  conduct  our  exploration,
development, and operation activities. The failure to comply with the regulations and terms of permits and licenses may result in fines or other penalties or in revocation of a
permit or license or loss of a prospect.

General

While none of the lands on which the Elk Creek Project is proposed to be built are owned by the U.S. Government, mining rights on public lands are governed by the
General Mining Law of 1872, as amended, which allows for the location of mining claims on certain federal lands upon the discovery of a valuable mineral deposit and
compliance with location requirements. The exploration of mining properties and development and operation of mines is governed by both federal and state laws. Federal
laws that govern mining claim location and maintenance and mining operations on federal lands are generally administered by the Bureau of Land Management. Additional
federal laws, governing mine safety and health, also apply. State laws also require various permits and approvals before exploration, development or production operations
can begin. Among other things, a reclamation plan must typically be prepared and approved, with financial assurance provided in the amount of projected reclamation costs.
The  financial  assurance  is  used  to  ensure  that  proper  reclamation  takes  place  and  will  not  be  released  until  that  time.  Local  jurisdictions  may  also  impose  permitting
requirements, such as conditional use permits or zoning approvals.

Environmental Regulation

Our mineral projects are subject to various federal, state and local laws and regulations governing protection of the environment. These laws are continually changing
and, in general, are becoming more restrictive. The development, operation, closure, and reclamation of mining projects in the U.S. requires numerous notifications, permits,
authorizations, and public agency decisions. Compliance with environmental and related laws and regulations requires us to obtain permits issued by regulatory agencies and
to file various reports and keep records of our operations. Certain of these permits require periodic renewal or review of their conditions and may be subject to a public
review process during which opposition to our proposed operations may be encountered. We are currently operating under various permits for activities connected to mineral
exploration, reclamation, and environmental considerations. Our policy is to conduct business in a way that safeguards public health and the environment. We believe that
our operations are conducted in material compliance with applicable laws and regulations.

Changes  to  current  local,  state,  or  federal  laws  and  regulations  in  the  jurisdictions  where  we  operate  could  require  additional  capital  expenditures  and  increased

operating and/or reclamation costs. Although we are unable to predict

6

 
 
 
 
 
 
 
 
 
 
 
 
what additional legislation, if any, might be proposed or enacted, additional regulatory requirements could impact the economics of our projects.

Environmental Regulation - U.S. Federal Laws

The Comprehensive Environmental, Response, Compensation, and Liability Act (“CERCLA”), and comparable state statutes, impose strict, joint, and several liability
on  current  and  former  owners  and  operators  of  sites  and  on  persons  who  disposed  of  or  arranged  for  the  disposal  of  hazardous  substances  found  at  such  sites.  It  is  not
uncommon  for  the  government  to  file  claims  requiring  clean-up  actions  and/or  demands  for  reimbursement  for  government-incurred  clean-up  costs  or  natural  resource
damages. It is also not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous
substances released into the environment. The Resource Conservation and Recovery Act (“RCRA”), and comparable state statutes, govern the disposal of solid waste and
hazardous waste and authorize the imposition of substantial fines and penalties for noncompliance, as well as requirements for corrective actions. CERCLA, RCRA, and
comparable state statutes can impose liability for clean-up of sites and disposal of substances found on exploration, mining and processing sites long after activities on such
sites have been completed.

The  Clean Air Act,  as  amended  (“CAA”),  restricts  the  emission  of  air  pollutants  from  many  sources,  including  mining  and  processing  activities. Any  future  mining
operations by the Company may produce air emissions, including fugitive dust and other air pollutants from stationary equipment, storage facilities, and the use of mobile
sources such as trucks and heavy construction equipment, which are subject to review, monitoring and/or control requirements under the CAA and state air quality laws.
New facilities may be required to obtain permits before work can begin, and existing facilities may be required to incur capital costs in order to remain in compliance. In
addition, permitting rules may impose limitations on our production levels or result in additional capital expenditures in order to comply with the rules.

The  National  Environmental  Policy  Act  (“NEPA”)  requires  federal  agencies  to  integrate  environmental  considerations  into  their  decision-making  processes  by
evaluating the environmental impacts of their proposed actions, including issuance of permits to mining facilities and assessing alternatives to those actions. If a proposed
action  could  significantly  affect  the  environment,  the  agency  must  prepare  either  a  detailed  statement  known  as  an  Environmental  Impact  Statement  (“EIS”),  or  a  less
detailed statement known as an Environmental Assessment (“EA”). The EPA, other federal agencies, and any interested third parties can review and comment on the scope
of the EIS or EA and the adequacy of any findings set forth in the draft and final EIS or EA. This process can cause delays in issuance of required permits or result in
changes to a project to mitigate its potential environmental impacts, which can in turn impact the economic feasibility of a proposed project.

The Clean Water Act (“CWA”), and comparable state statutes, impose restrictions and controls on the discharge of pollutants into waters of the U.S. The discharge of
pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. The CWA regulates storm
water from mining facilities and requires a storm water discharge permit or Stormwater Pollution Prevention Plan for certain activities. Such a permit requires the regulated
facility  to  monitor  and  sample  storm  water  run-off  from  its  operations.  The  CWA  and  regulations  implemented  thereunder  also  prohibit  discharges  of  dredged  and  fill
material in wetlands and other waters of the U.S. unless authorized by an appropriately issued permit. The CWA and comparable state statutes provide for civil, criminal, and
administrative  penalties  for  unauthorized  discharges  of  pollutants,  and  impose  liability  on  parties  responsible  for  those  discharges  for  the  costs  of  cleaning  up  any
environmental damage caused by the release and for natural resource damages resulting from the release.

The  Safe  Drinking  Water  Act  (“SDWA”)  and  the  Underground  Injection  Control  (“UIC”)  program  promulgated  thereunder,  regulate  the  drilling  and  operation  of
subsurface injection wells. The EPA directly administers the UIC program in some states and in others the responsibility for the program has been delegated to the state. The
program requires that a permit be obtained before drilling a disposal or injection well. Violation of these regulations and/or contamination of groundwater by mining-related
activities may result in fines, penalties, and remediation costs, among other sanctions and liabilities under the SDWA and state laws. In addition, third-party claims may be
filed by landowners and other parties claiming damages for alternative water supplies, property damages, and bodily injury.

Environmental Regulation − Nebraska

Nebraska has a well-developed set of environmental regulations and responsible agencies but does not have clearly defined regulations with respect to permitting mines.
As such, review of the project and the issuance of permits by Nebraska agencies and regulatory bodies could potentially impact the total time to market for our Elk Creek
Project. Other Nebraska regulations govern operating and design standards for the construction and operation of any source of air emissions and landfill operations. Any
changes to these laws and regulations could have an adverse impact on our financial performance and results of operations by, for example, requiring changes to operating
conditions, technical criteria, fees, or surety requirements. The most stringent permit related to air quality is known as a Prevention of Significant Deterioration (“PSD”)
permit,  which  requires  the  applicant  to  demonstrate  compliance  with  NAAQS  and  Best Available  Control Technology  (“BACT”)  for  the  control  of  air  emissions.  If  the
facility exceeds the potential to emit thresholds for such a permit and is thus subject to PSD requirements, permanent construction at the project site may not begin until the
responsible  agency  issues  the  PSD  permit.  For  facilities  in  Nebraska  with  potential  emissions  below  PSD  thresholds,  a  state  air  construction  permit  is  needed. The  state
permit also requires a demonstration of compliance with NAAQS but does not require a BACT demonstration and further allows construction at a subject facility to proceed
ahead of permit issuance through an established variance process.

Human Capital

The  Company’s  ability  to  continue  to  progress  the  Elk  Creek  Project  will  depend  on  its  ability  to  attract  and  retain  individuals  with  (among  other  skills)  financial,
administrative,  engineering,  geological  and  mining  skills,  and  knowledge  of  our  industry  and  targeted  markets.  Much  of  the  necessary  specialized  skills  and  knowledge
required  by  the  Company  as  a  mineral  exploration  company  are  available  from  the  Company’s  current  management  team  and  Board  of  Directors. The  Company  retains
outside consultants if additional specialized skills and knowledge are required.

As of June 30, 2023, we had seven full-time employees as well as one contract employee. In addition, we use consultants with specific skills to assist with various

aspects of our corporate affairs, project evaluation, due diligence, corporate governance and property management.

Our  compensation  programs  are  designed  to  align  compensation  of  our  employees  with  the  Company’s  performance  and  to  provide  the  proper  incentives  to  attract,
retain and motivate employees to achieve superior results. The structure of our compensation programs balances competitive wages and benefits and incentive earnings for
both short-term and long-term performance.

Our priority to maintain a culture of ethical performance as a core value is reflected in the Company’s Code of Business Conduct and Ethics (the “Code of Conduct”)
and  other  related  policies.  Oversight  is  provided  by  the  Company’s  Board  of  Directors  and,  for  specific  areas  of  performance,  by  committees  of  the  Board  of  Directors.
Employees are required to review the Code of Conduct on a periodic basis. Our compensation programs also include consideration of ethical performance in determining
incentive awards.

The  Company  also  provides  a  robust  suite  of  benefits  to  our  employees,  including  401(k)  participation,  medical-insurance  options,  and  programs  to  encourage  and

support the whole person.

“possible,” and similar expressions, or statements that events, conditions, or results “will,” “may,” “could,” or “should” (or the negative and grammatical variations of any of
these  terms)  occur  or  be  achieved. Any  statements  that  express  or  involve  discussions  with  respect  to  predictions,  expectations,  beliefs,  plans,  projections,  objectives,
assumptions, or future events or performance (often, but not always, using words or phrases such as “expects” or “does not expect,” “is expected,” “anticipates” or “does not
anticipate,” “plans,” “estimates,” or “intends,” or stating that certain actions, events, or results “may,” “could,” “would,” “might,” or “will” be taken, occur or be achieved)
are not statements of historical fact and may be forward-looking statements. Such forward-looking statements reflect the Company’s current views with respect to future
events and are subject to certain known and unknown risks, uncertainties, and assumptions. Many factors could cause actual results, performance, or achievements to be
materially different from any future results, performance, or achievements that may be expressed or implied by such forward-looking statements, including, among others,
risks  related  to  the  following:  NioCorp’s  ability  to  recognize  the  anticipated  benefits  of  the  Transactions,  including  NioCorp’s  ability  to  access  the  full  amount  of  the
expected net proceeds under the Yorkville Equity Facility Financing Agreement over the next three years; unexpected costs related to the Transactions; the outcome of any
legal proceedings that may be instituted against NioCorp following closing of the Transactions; NioCorp’s ability to receive a final commitment of financing from EXIM on
the anticipated timeline, on acceptable terms, or at all; NioCorp’s ability to continue to meet Nasdaq listing standards; NioCorp’s ability to operate as a going concern; risks
relating  to  the  Common  Shares,  including  price  volatility,  lack  of  dividend  payments  and  dilution  or  the  perception  of  the  likelihood  any  of  the  foregoing;  NioCorp’s
requirement  of  significant  additional  capital;  the  extent  to  which  NioCorp’s  level  of  indebtedness  and/or  the  terms  contained  in  agreements  governing  NioCorp’s
indebtedness or the Yorkville Equity Facility Financing Agreement may impair NioCorp’s ability to obtain additional financing; covenants contained in agreements with
NioCorp’s secured creditors that may affect its assets; NioCorp’s limited operating history; NioCorp’s history of losses; the restatement of NioCorp’s consolidated financial
statements as of and for the fiscal years ended June 30, 2022 and 2021 and the interim periods ended September 30, 2021, December 31, 2021, March 31, 2022, September
30, 2022 and December 31, 2022 and the impact of such restatement on NioCorp’s future financial statements and other financial measures; the material weaknesses in
NioCorp’s internal control over financial reporting, NioCorp’s efforts to remediate such material weaknesses and the timing of remediation; the possibility that NioCorp may
qualify as a PFIC under the Code; the potential that the Transactions could result in NioCorp becoming subject to materially adverse U.S. federal income tax consequences
as a result of the application of Section 7874 and related sections of the Code; cost increases for NioCorp’s exploration and, if warranted, development projects; a disruption
in, or failure of, NioCorp’s information technology systems, including those related to cybersecurity; equipment and supply shortages; variations in the market demand for,
and  prices  of,  niobium,  scandium,  titanium  and  rare  earth  products;  current  and  future  offtake  agreements,  joint  ventures,  and  partnerships;  NioCorp’s  ability  to  attract
qualified management; the effects of global health crises on NioCorp’s business plans, financial condition and liquidity; estimates of mineral resources and reserves; mineral
exploration  and  production  activities;  feasibility  study  results;  the  results  of  metallurgical  testing;  changes  in  demand  for  and  price  of  commodities  (such  as  fuel  and
electricity) and currencies; competition in the mining industry; changes or disruptions in the securities markets; legislative, political or economic developments, including
changes in federal and/or state laws that may significantly affect the mining industry; the impacts of climate change, as well as actions taken or required by governments
related  to  strengthening  resilience  in  the  face  of  potential  impacts  from  climate  change;  the  need  to  obtain  permits  and  comply  with  laws  and  regulations  and  other
regulatory requirements; the timing and reliability of sampling and assay data; the possibility that actual results of work may differ from

9

 
 
 
 
projections/expectations  or  may  not  realize  the  perceived  potential  of  NioCorp’s  projects;  risks  of  accidents,  equipment  breakdowns,  and  labor  disputes  or  other
unanticipated  difficulties  or  interruptions;  the  possibility  of  cost  overruns  or  unanticipated  expenses  in  development  programs;  operating  or  technical  difficulties  in
connection with exploration, mining, or development activities; the management of the water balance at the Elk Creek Project site; land reclamation requirements related to
the  Elk  Creek  Project;  the  speculative  nature  of  mineral  exploration  and  development,  including  the  risks  of  diminishing  quantities  of  grades  of  reserves  and  resources;
claims on the title to NioCorp’s properties; potential future litigation; and NioCorp’s lack of insurance covering all of NioCorp’s operations.

Should  one  or  more  of  these  risks  or  uncertainties  materialize,  or  should  underlying  assumptions  prove  incorrect,  actual  results  may  vary  materially  from  those
described  herein. This  list  is  not  exhaustive  of  the  factors  that  may  affect  any  of  the  Company’s  forward-looking  statements.  Forward-looking  statements  are  statements
about the future and are inherently uncertain, and actual achievements of the Company or other future events or conditions may differ materially from those reflected in the
forward-looking statements due to a variety of risks, uncertainties, and other factors, including without limitation those discussed under Item 1A. “Risk Factors” below.

The Company’s forward-looking statements contained in this Annual Report on Form 10-K are based on the beliefs, expectations, and opinions of management as of the
date of this Annual Report on Form 10-K. The Company does not assume any obligation to update forward-looking statements if circumstances or management’s beliefs,
expectations, or opinions should change, except as required by law. For the reasons set forth above, investors should not attribute undue certainty to, or place undue reliance
on, forward-looking statements.

ITEM 1A. RISK FACTORS

Our business activities are subject to significant risks, including those described below. You should carefully consider these risks. If any of the described risks occurs,
our  business,  financial  position,  and  results  of  operations  could  be  materially  adversely  affected.  Such  risks  are  not  the  only  ones  we  face,  and  additional  risks  and
uncertainties not presently known to us or that we currently deem immaterial may also affect our business. This report contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of a number of factors, including the risks
described below. See “Forward-Looking Statements” under Item 1., “Business.”

Risks Related to Our Business

Our ability to operate as a going concern is in doubt.

The notes that accompany our consolidated financial statements for the year ended June 30, 2023, disclose that substantial doubt exists as to our ability to continue as a

going concern. The consolidated financial statements included in this Annual Report

10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
on Form 10-K have been prepared under the assumption that we will continue as a going concern. We are a development stage issuer and we have incurred losses since our
inception.

We currently have no historical recurring source of revenue and our ability to continue as a going concern is dependent on our ability to raise capital to fund our future
exploration and working capital requirements or our ability to profitably execute our business plan. Our plans for the long-term return to and continuation as a going concern
include financing our future operations through sales of our Common Shares and/or debt and the potential profitable exploitation of our Elk Creek Project. Additionally,
capital markets and general economic conditions in the U.S. and Canada may impose significant obstacles to raising the required funds. As discussed further below, while we
have been successful in doing so in the past, there can be no assurance we will be able to raise funds in the future. These factors raise substantial doubt about our ability to
continue as a going concern.

We will require significant additional capital to fund our business plan.

We will be required to expend significant funds to develop our existing properties and to identify and acquire additional properties to diversify our property portfolio.

We anticipate that we will be required to make substantial capital expenditures for the development of our Elk Creek Project.

As of June 30, 2023, the Company had cash of $2.3 million and working capital of $0.2 million, compared to cash of $5.3 million and working capital of $0.6 million

on June 30, 2022.

As of June 30, 2023, the Company’s current planned operational needs are approximately $11.8 million through the end of fiscal 2024. From the date of this Annual
Report on Form 10-K, the Company anticipates that it does not have sufficient cash to continue to fund basic operations for the next twelve months. This includes general
overhead costs, expected costs relating to securing financing necessary for the Elk Creek Project, satisfying outstanding accounts payable, and potential retirement of our
short-term debt obligations. Access to additional funds will be utilized to fund basic operations as well as to further advance the Elk Creek Project through substantive near-
term milestones.

Except  for  the  net  funds  of  $1.5  million  received  from  financing  transactions  closed  in  September  2023,  the  potential  funding  under  the  Yorkville  Equity  Facility
Financing, discussed below under “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Financing
Activities,” and the potential exercise of Options and Warrants, we currently have no further funding commitments or arrangements for additional financing at this time, and
there is no assurance that we will be able to obtain any such additional financing on acceptable terms, if at all. In addition, pursuant to the Exchange Agreement, NioCorp is
restricted from issuing equity or equity-linked securities (other than Common Shares) or any preferred equity or non-voting equity if such issuance would adversely impact
the rights of the holders of the shares of Class B common stock of ECRC, without the consent of the holders of a majority of the shares of Class B common stock of ECRC.
The Yorkville Convertible Debt Financing Agreement also contains certain covenants that, among other things, limit NioCorp’s ability to use the proceeds from the Yorkville
Convertible Debt Financing to repay related party debt or to enter into any variable rate transaction, including issuances of equity or debt securities that are convertible into
Common Shares at variable rates and any equity line of credit, ATM agreement or other continuous offering of Common Shares, other than with Yorkville, subject to certain
exceptions. Notwithstanding the restrictions set forth in the Exchange Agreement and the Yorkville Convertible Debt Financing Agreement, there is significant uncertainty
that we would be able to secure any additional financing in the current equity or debt markets.

We are actively pursuing additional sources of debt and equity financing, and while we have been successful in doing so in the past, there can be no assurance we will

be able to do so in the future.

Our ability to obtain necessary funding for these purposes, in turn, depends upon a number of factors, including the status of the national and worldwide economy and
the price of the products we intend to produce. We may not be successful in obtaining the required financing or, if we can obtain such financing, such financing may not be
on terms that are favorable to us.

In  addition,  the  EXIM  Financing  discussed  below  under  “Management’s  Discussion  and Analysis  of  Financial  Condition  and  Results  of  Operations  –  Liquidity  and
Capital  Resources”  is  subject  to,  among  other  matters,  the  satisfactory  completion  of  due  diligence,  the  negotiation  and  settlement  of  final  terms,  and  the  negotiation  of
definitive

11

 
 
 
 
 
 
 
 
 
 
 
 
documentation. There can be no assurance that the EXIM Financing will be completed on the terms described herein or at all.

Our inability to access sufficient capital for our operations could have a material adverse effect on our financial condition, results of operations, or prospects. Sales of
substantial amounts of securities may have a highly dilutive effect on our ownership or share structure. Sales of a large number of Common Shares in the public markets, or
the potential for such sales, could decrease the trading price of the Common Shares and could impair our ability to raise capital through future sales of Common Shares. We
have not yet commenced commercial production at any of our properties and, as such, have not generated positive cash flows to date and have no reasonable prospects of
doing so unless successful commercial production can be achieved at our Elk Creek Project. We expect to continue to incur negative investing and operating cash flows until
such  time  as  we  enter  into  successful  commercial  production. This  will  require  us  to  deploy  our  working  capital  to  fund  such  negative  cash  flow  and  to  seek  additional
sources of financing. There is no assurance that any such financing sources will be available or sufficient to meet our requirements. There is no assurance that we will be
able to continue to raise equity capital or to secure additional debt financing, or that we will not continue to incur losses.

We have a limited operating history on which to base an evaluation of our business and prospects.

Since  our  inception,  we  have  had  no  revenue  from  operations.  We  have  no  history  of  producing  products  from  any  of  our  properties.  Our  Elk  Creek  Project  is  a
development stage property. Advancing our Elk Creek Project from a development stage property to a production stage property will require significant capital and time, and
successful commercial production from the Elk Creek Property will be subject to permitting and construction of the mine, processing plants, roads, and other related works
and infrastructure. As a result, we are subject to all of the risks associated with developing and establishing new mining operations and business enterprises including:

● the  timing  and  cost,  which  can  be  considerable,  of  further  exploration,  preparing  feasibility  studies,  permitting,  engineering  and  construction  of  infrastructure,

mining, and processing facilities;

● the availability and costs of drilling equipment, exploration personnel, skilled labor, and mining and processing equipment, if required;
● the availability and cost of appropriate smelting and/or refining arrangements, if required;
● compliance with environmental and other governmental approval and permit requirements;
● the availability of funds to finance exploration, development, permitting, and construction activities, as warranted;
● potential opposition from non-governmental organizations, local groups, or local residents that may delay or prevent development activities;
● potential increases in exploration, construction, and operating costs due to changes in the cost of fuel, power, materials, and supplies; and
● potential shortages of mining, mineral processing, hydrometallurgical, pyrometallurgical, construction, and other facilities-related supplies.

The  costs,  timing,  and  complexities  of  exploration,  development,  engineering,  and  construction  activities  may  be  increased  by  the  location  of  our  properties  and
competition  from  other  mineral  exploration  and  mining  companies.  It  is  common  for  exploration  companies  to  experience  unexpected  problems  and  delays  during
development,  if  commenced,  including  engineering,  procurement,  construction,  commissioning,  and  ramp-up.  Accordingly,  our  activities  may  not  result  in  profitable
operations and we may not succeed in establishing operations or profitably producing products at any of our current or future properties, including our Elk Creek Project.

We have a history of losses and expect to continue to incur losses in the future.

We  have  incurred  losses  since  inception,  have  negative  cash  flow  from  operating  activities,  and  expect  to  continue  to  incur  losses  in  the  future.  We  incurred  the

following net losses attributable to the Company during each of the following periods:

● $40.1 million for the year ended June 30, 2023;
● $10.9 million for the year ended June 30, 2022; and
● $4.8 million for the year ended June 30, 2021.

12

 
 
 
 
 
 
 
 
 
 
 
We expect to continue to incur losses unless and until such time as one of our properties enters into commercial production and generates sufficient revenues to fund
continuing operations. We recognize that if we are unable to generate significant revenues from operations and dispositions of our properties, we will not be able to earn
profits  or  continue  operations. At  this  early  stage  of  our  operation,  we  also  expect  to  face  the  risks,  uncertainties,  expenses,  and  difficulties  frequently  encountered  by
companies at the start-up stage of their business development. We cannot be sure that we will be successful in addressing these risks and uncertainties and our failure to do
so could have a materially adverse effect on our financial condition.

Increased costs could affect our financial condition.

We anticipate that costs at our projects that we may explore or develop will frequently be subject to variation from one year to the next due to a number of factors, such
as changing ore grade, metallurgical performance, and revisions to mine plans, if any, in response to the physical shape and location of the ore body. In addition, costs are
affected by the price of commodities such as fuel, steel, aluminum, iron, chemicals, natural gas, fresh water, and electricity, as well as by government actions such as tariffs.
Such commodities are at times subject to volatile price movements, including increases that could make production at certain operations less profitable or not profitable at
all. A material increase in costs at any significant location could have a significant effect on our profitability.

A disruption in, or failure of our third-party service providers’ IT systems, including those related to cybersecurity, could adversely affect our business operations and
financial performance.

We rely on the accuracy, capacity, and security of our third-party service providers’ IT systems for the operations of many of our business processes and to comply with
regulatory, legal, and tax requirements. We are dependent on third parties to provide important IT services relating to, among other things, operational technology at our
facilities, human resources, electronic communications, and certain finance functions. Despite the security measures that our third-party service providers have implemented,
including  those  related  to  cybersecurity,  their  systems  could  be  breached  or  damaged  by  computer  viruses,  natural  or  man-made  incidents  or  disasters,  or  unauthorized
physical or electronic access. Though our third-party service providers have controls in place, we cannot provide assurance that a cyber-attack will not occur. Furthermore,
we may have little or no oversight with respect to security measures employed by third-party service providers, which may ultimately prove to be ineffective at countering
threats. Failures of our third-party service providers’ IT systems, whether caused maliciously or inadvertently, may result in the disruption of our business processes, or in
the  unauthorized  release  of  sensitive,  confidential,  or  otherwise  protected  information  or  result  in  the  corruption  of  data,  which  could  adversely  affect  our  business
operations and financial performance. In addition, we may be required to incur significant costs to protect against and, if required, remediate the damage caused by such
disruptions or system failures in the future.

A shortage of equipment and supplies could adversely affect our ability to operate our business.

We  are  dependent  on  various  supplies  and  equipment  to  carry  out  our  mining  exploration  and,  if  warranted,  project  development  operations.  The  shortage  of  such
supplies, equipment, and parts could have a material adverse effect on our ability to carry out our operations and could therefore limit, or increase the cost of, production.
Ongoing disruptions to the world’s economy, including issues related to supply chains, inflation, and increased raw material and labor costs, may delay our ability to secure
supplies and equipment for the Elk Creek Project on a timely basis.

Joint ventures and other partnerships, including offtake arrangements, may expose us to risks.

We have entered into three offtake agreements and one letter of intent related to our Elk Creek Project as well as agreements related to the supply of natural gas and
electricity to the project site, and may enter into joint ventures or partnership arrangements, including additional offtake agreements, with other parties in relation to the
exploration, development, and production of certain of the properties in which we have an interest. Any failure of such other companies to meet their obligations to us or to
third parties, or any disputes with respect to the parties’ respective rights and obligations, or price fluctuations and termination provisions related to such agreements, could
have a material adverse effect on us, the development and production at our properties, including the Elk Creek Project, the joint ventures, if any, or their properties and
therefore could have a material adverse effect on our results of operations, financial performance, cash flows, and the price of our Common Shares.

13

 
 
 
 
 
 
 
 
 
 
 
We  may  experience  difficulty  attracting  and  retaining  qualified  management  to  meet  the  needs  of  our  anticipated  growth,  and  the  failure  to  manage  our  growth
effectively could have a material adverse effect on our business and financial condition.

We are dependent on a relatively small number of key employees, including our Chief Executive Officer. The loss of any officer could have an adverse effect on us. We

have no life insurance on any individual, and we may be unable to hire a suitable replacement for them on favorable terms, should that become necessary.

The effect on the capital markets and the economy of recent global events, including inflation, volatility in commodity prices, supply chain uncertainty, and increases in
raw material and labor costs, could have an adverse effect on NioCorp’s business plans, financial condition, and liquidity.

Certain events have effected, and continue to effect, the global and United States economies, including increased inflation, volatility in commodity prices, supply chain
uncertainty, and increases in raw material and labor costs. In addition, in the U.S., the Federal Reserve has begun raising interest rates sharply, the continuation of which
could lead to a recession with uncertain and potentially severe impacts upon most operating sectors. We cannot predict how this will affect our business, but the impact may
be adverse.

Although it is not possible to predict the ultimate impact of these factors on NioCorp’s business plans, financial position, or liquidity, such impacts that may be material
include,  but  are  not  limited  to:  (i)  delays  in  the  completion  of  the  mine  and  surface  engineering  designs  and  uncertainty  regarding  our  ability  to  finalize  necessary
Engineering, Procurement, and Construction (“EPC”) agreements as a result of disruptions in the businesses of our engineering consultants and key contractors for the Elk
Creek Project, (ii) reduced availability and increased costs of employees, (iii) a negative impact on our liquidity position, and (iv) increased costs and less ability to access
funds in the capital markets. The full extent to which these factors may continue to impact our business will depend on future developments, which continue to be highly
uncertain and cannot be predicted at this time.

In addition, we cannot predict the impact that recent global events, including inflation, volatility in commodity prices, supply chain uncertainty, and increases in raw
material and labor costs will have on our customers, suppliers, vendors, and other business partners, and each of their financial conditions; however, any material effect on
these parties could adversely impact us.

It may be difficult to enforce judgments or bring actions outside the U.S. against us and certain of our directors.

We are a Canadian corporation and, as a result, it may be difficult or impossible for an investor to do the following:

● enforce in courts outside the U.S. judgments obtained in U.S. courts based upon the civil liability provisions of U.S. federal securities laws against these persons

and the Company; or

● bring in courts outside the U.S. an original action to enforce liabilities based upon U.S. federal securities laws against these persons and the Company.

The Company may not realize all or any of the anticipated benefits expected as a result of the Transactions.

The  listing  of  the  Common  Shares  on  Nasdaq  may  not  provide  the  anticipated  benefits  of  broader  access  to  capital  and  financing  alternatives  or  otherwise  enhance
NioCorp’s public profile. If the Company is not successful in realizing these anticipated benefits, including the anticipated benefits of listing the Common Shares on the
Nasdaq and the anticipated acceleration of financing efforts to advance, complete construction, and commence operation of the Elk Creek Project, such consequences may
adversely affect the Company’s results of operations, cash flows, financial position, and the price of our Common Shares.

We may not recognize the full value of the Yorkville Equity Facility Financing Agreement and may not receive any proceeds from the exercise of the Financing
Warrants,  the  NioCorp Assumed  Warrants,  and  our  other  outstanding  Warrants,  and  the  potential  adverse  effect  on  the  prevailing  market  prices  for  our  Common
Shares as a result of sales, or the perception of future sales, of Common Shares could adversely affect our ability to raise additional capital.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Although we have entered into the Yorkville Equity Facility Financing Agreement, we may not recognize the full value thereof. Specifically, our ability to sell Common
Shares to Yorkville pursuant to the Yorkville Equity Facility Financing Agreement is subject to certain restrictions and limitations, which may prevent us from selling the
full Commitment Amount prior to the expiration of the Commitment Period. Our ability to recognize the full value of the Yorkville Equity Facility Financing Agreement
may be further impeded by the potential negative pressure on the market price of our Common Shares as a result of sales, or the perception of future sales, of Common
Shares by us or by other security holders. As a result, there can be no assurance that we will receive all or even a significant portion of the proceeds that we expect to receive
in connection with the Yorkville Equity Facility Financing Agreement.

In  addition,  upon  exercise,  we  will  receive  the  cash  exercise  price  of  the  Financing  Warrants,  the  NioCorp Assumed  Warrants,  and  our  other  outstanding  Warrants
(assuming,  with  respect  to  the  Financing  Warrants  and  the  NioCorp Assumed  Warrants,  that  they  are  not  exercised  on  a  cashless  basis).  We  believe  the  likelihood  that
holders of the Financing Warrants, the NioCorp Assumed Warrants or other outstanding Warrants will exercise their Financing Warrants, NioCorp Assumed Warrants, or
other outstanding Warrants, and therefore, the amount of cash proceeds that we would receive, is, among other things, dependent upon the market price of our Common
Shares. For so long as the market price for our Common Shares is less than the applicable exercise price of the Financing Warrants, NioCorp Assumed Warrants, or other
outstanding  Warrants,  we  believe  such  holders  will  be  unlikely  to  exercise  their  Financing  Warrants,  NioCorp  Assumed  Warrants,  or  other  outstanding  Warrants.  The
potential adverse effect on the prevailing market price of our Common Shares as a result of sales of Common Shares by us or by other security holders, or the perception
that  such  sales  may  occur,  could  keep  the  market  price  for  our  Common  Shares  below  the  applicable  exercise  price  of  the  Financing  Warrants,  the  NioCorp Assumed
Warrants,  or  other  outstanding  Warrants.  Accordingly,  the  holders  of  the  Financing  Warrants,  the  NioCorp  Assumed  Warrants,  or  other  outstanding  Warrants  may  not
exercise their Financing Warrants, NioCorp Assumed Warrants, or other outstanding Warrants before they expire, and we may not receive any proceeds from the exercise of
the Financing Warrants, the NioCorp Assumed Warrants, or other outstanding Warrants.

We incurred significant debt in connection with the Transactions, including upon issuance of the Convertible Debentures, and we require significant additional capital to
operate our business. For example, notwithstanding whether we are able to recognize the full value of the Yorkville Equity Facility Financing Agreement or receive the cash
exercise price of the Financing Warrants, the NioCorp Assumed Warrants, or other outstanding Warrants, we are obligated to repay or issue Common Shares upon settlement
of  the  full  $16.0  million  aggregate  principal  amount  of  the  Convertible  Debentures,  plus  accrued  interest.  Such  significant  additional  debt  could  adversely  affect  our
business,  which  may  prevent  us  from  fulfilling  our  obligations  with  respect  to  our  existing  debt  or  obtaining  future  financing.  Further,  the  Yorkville  Convertible  Debt
Financing Agreement restricts us from pursuing certain variable rate financing transactions, which could impair our ability to obtain additional financing on terms that are
favorable, or at all. In addition, if the market price of the Common Shares were to drop as a result of sales, or the perception of future sales, of Common Shares by us or by
other security holders, this might impede our ability to raise additional capital. Our inability to obtain additional financing on terms that are favorable, or at all, could have a
material adverse effect on our financial condition, results of operations and prospects.

The Company has identified material weaknesses in its internal control over financial reporting. If not remediated, the Company’s failure to establish and maintain
effective disclosure controls and procedures and internal control over financial reporting could result in material misstatements in its financial statements and a failure
to meet its reporting and financial obligations, each of which could have a material adverse effect on the Company’s financial condition and the trading price of the
Common Shares.

Our management has identified material weaknesses in its internal control over financial reporting relating to its control over the consideration of all related relevant
accounting  guidance  for  non-routine  transactions,  its  control  over  the  design  and  maintenance  of  an  effective  control  environment  and  risk  assessment  process,  and  its
monitoring controls over the timely remediation of identified internal control weaknesses. A material weakness is a deficiency, or a combination of deficiencies, in internal
control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be
prevented or detected on a timely basis.

15

 
 
 
 
 
 
 
As discussed in Item 9A, “Controls and Procedures,” of this Annual Report on Form 10-K, the Company’s management has assessed the effectiveness of its internal

control over financial reporting and its disclosure controls and procedures and concluded that they were not effective as of June 30, 2023.

The  Company  is  committed  to  remediating  its  material  weaknesses  as  promptly  as  possible.  Management  is  in  the  process  of  implementing  its  remediation  plan.
However, there can be no assurance as to when the material weaknesses will be remediated or that additional material weaknesses will not arise in the future. If the Company
is  unable  to  maintain  effective  internal  control  over  financial  reporting,  its  ability  to  record,  process  and  report  financial  information  timely  and  accurately  could  be
adversely affected, which could subject the Company to litigation or investigations, require management resources, increase costs, negatively affect investor confidence and
adversely impact the trading price of the Common Shares.

We may face litigation and other risks as a result of the material weaknesses in our internal control over financial reporting.

We  identified  material  weaknesses  in  our  internal  control  over  financial  reporting  that  exist  as  of  June  30,  2023. As  a  result  of  such  material  weaknesses  and  other
matters raised or that may in the future be raised by the SEC or the Canadian securities regulators, we face potential for litigation or other disputes, which may include,
among  others,  claims  invoking  the  federal  and  state  securities  laws,  contractual  claims  or  other  claims  arising  from  the  material  weaknesses  in  our  internal  control  over
financial reporting and the preparation of our financial statements. As of the date of this Annual Report on Form 10-K, we have no knowledge of any such litigation or
dispute. However, we can provide no assurance that such litigation or dispute will not arise in the future. Any such litigation or dispute, whether successful or not, could
adversely affect our business, financial condition and results of operations.

Risks Related to Mining and Development

We  face  numerous  uncertainties  in  estimating  our  mineral  reserves  and  resources  and  inaccuracies  in  our  estimates  could  result  in  lower  than  expected  revenues,
higher than expected costs and decreased profitability.

A mineral is economically recoverable when the price at which we may sell the mineral exceeds the costs and expenses of mining and selling the mineral. Forecasts of
our future performance are based on, among other things, estimates of our mineral reserves. We base our reserve and resource information on engineering, economic and
geological data assembled and analyzed by qualified persons, which include various engineers and geologists on our staff and of third parties. Our estimates are also subject
to SEC regulations regarding classification of reserves and resources, including S-K 1300. Our reserve and resource estimates as to both quantity and quality are updated
from  time  to  time  to  reflect  additional  information  received.  There  are  numerous  uncertainties  inherent  in  estimating  quantities  and  qualities  of  mineral  reserves  and
resources, including many factors beyond our control.

Estimates of mineral reserves and resources necessarily depend upon a number of variable factors and assumptions, any one of which may, if incorrect, result in an

estimate that varies considerably from actual results. These factors and assumptions include, but are not limited to:

● geologic and mining conditions, which may not be fully identified by available exploration data and may differ from our experience;
● demand for the minerals that we plan to produce;
● current and future market prices for minerals and contractual arrangements;
● current  and  future  operating  costs  and  capital  expenditures  may  exceed  estimates,  notwithstanding  that,  under  S-K  1300,  operating  cost  and  capital  expenditure

estimates in feasibility studies must have an accuracy level of at least ±15% and a contingency range not exceeding 10%;

● additional capital expenditures related to the modification of the proposed surface plant related to the potential addition of rare earth elements;
● severance and excise taxes, royalties and development and reclamation costs;
● future mining technology improvements;
● the effects of regulation by governmental agencies;
● the ability to obtain, maintain and renew all required permits;
● employee health and safety; and
● historical production from the area compared with production from other producing areas.

16

 
 
 
 
 
 
 
 
 
 
 
The conversion of reported mineral resources to mineral reserves should not be assumed, and the reclassification of reported mineral resources from lower to higher
levels of geological confidence should not be assumed. As such, actual mineral tonnage recovered from identified reserves, and revenues and expenditures with respect to
our reserves, may vary materially from estimates. Thus, these estimates may not accurately reflect our actual reserves. Any material inaccuracy in our estimates related to
our reserves could result in lower than expected revenues, higher than expected costs, or decreased profitability, which could materially and adversely affect our business,
results of operations, financial position, and cash flows.

The nature of mineral exploration and production activities involves a high degree of risk and the possibility of uninsured losses.

Exploration for and the production of minerals is highly speculative and involves much greater risk than many other businesses. Most exploration programs do not result
in the discovery of mineralization, and any mineralization discovered may not be of sufficient quantity or quality to be profitably mined. Our operations are, and any future
development  or  mining  operations  we  may  conduct  will  be,  subject  to  all  of  the  operating  hazards  and  risks  normally  incident  to  exploring  for  and  developing  mineral
properties, such as, but not limited to:

● economically insufficient mineralized material;
● fluctuation in production costs that make production uneconomical;
● labor disputes;
● unanticipated variations in grade and other geologic problems;
● environmental hazards;
● water conditions;
● difficult surface or underground conditions;
● industrial accidents;
● metallurgical, pyrometallurgical, and other processing problems;
● mechanical and equipment performance problems;
● failure of dams, stockpiles, wastewater transportation systems, or impoundments;
● unusual or unexpected rock formations; and
● personal injury, fire, flooding, cave-ins, and landslides.

Any  of  these  risks  can  materially  and  adversely  affect,  among  other  things,  the  development  of  properties,  production  quantities  and  rates,  costs  and  expenditures,
potential revenues, and production dates. We currently have very limited insurance to guard against some of these risks. If we determine that capitalized costs associated
with any of our mineral interests are not likely to be recovered, we would incur a write-down of our investment in these interests. All of these factors may result in losses in
relation to amounts spent that are not recoverable, or that result in additional expenses.

We have no history of producing commercial products from our current mining properties and there can be no assurance that we will successfully establish mining
operations or profitably produce minerals.

We  have  no  history  of  producing  commercial  products  from  our  current  mining  properties.  We  do  not  produce  commercial  products  and  do  not  currently  generate
operating earnings. While we seek to move our Elk Creek Project from a development stage property to a production stage property, such efforts will be subject to all of the
risks associated with establishing new mining operations and business enterprises, including:

● the timing and cost, which are considerable, of the construction of mining and processing facilities;
● the availability and costs of skilled labor and equipment;
● compliance with environmental and other governmental approval and permit requirements;
● the availability of funds to finance construction and development activities;
● potential opposition from non-governmental organizations, local groups, or local residents that may delay or prevent development activities; and
● potential increases in construction and operating costs due to changes in the cost and availability of labor, fuel, power, materials, and equipment and supplies, and

the time elapsed since the most recent estimates of cost and availability were made.

17

 
 
 
 
 
 
 
 
 
 
It is common in new mining and processing operations to experience unexpected problems and delays during engineering, procurement, construction, commissioning,
and initial operations. In addition, our management and workforce will need to be expanded, and sufficient housing and other support systems for our workforce will have to
be established. This could result in delays in the commencement of production and increased costs of production. Accordingly, we cannot assure you that our activities will
result in profitable operations or that we will successfully establish mining and processing operations.

Results of metallurgical testing by us may not be favorable to, or as expected by, us.

We have completed significant bench, mini-pilot, and pilot scale metallurgical testing on material from the Elk Creek Project and will continue to complete necessary
metallurgical  testing  at  the  bench,  mini-pilot,  and  pilot  scale  as  the  exploration  and,  if  warranted,  development  of  the  Elk  Creek  Project  progresses.  There  can  be  no
assurance that the results of such metallurgical testing will be favorable to, or will be as expected by, us. Furthermore, there can be no certainty that metallurgical recoveries
obtained in bench or pilot scale tests will be achieved in either subsequent testing or commercial operations. The development of a complete metallurgical process to produce
saleable final products from the Elk Creek Project is a complex and resource-intensive undertaking that may result in overall schedule delays and increased project costs for
us.

Price volatility could have dramatic effects on our results of operations and our ability to execute our business plan.

The price of commodities varies on a daily basis. Niobium is a specialty metal and not a commonly traded commodity such as copper, zinc, gold, or iron ore. The price
of  niobium  tends  to  be  set  through  a  limited  long-term  offtake  market,  contracted  between  very  few  suppliers  and  purchasers.  The  world’s  largest  supplier  of  niobium,
Companhia Brasileira de Metalurgia e Mineração, supplies approximately 85% of the world’s niobium. Any attempt to suppress the price of niobium by such supplier, or an
increase in production by any supplier in excess of any increased demand, would have negative consequences on the price of niobium and, potentially, on our value. The
price of niobium may also be reduced by the discovery of new niobium deposits, which could not only increase the overall supply of niobium (causing downward pressure
on its price) but could draw new firms into the niobium industry that would compete with us.

Sc2O3 is used in solid oxide fuel cells and has the potential to become a valuable alloy with aluminum in the aerospace and automotive industries. Supply of scandium
has been sporadic in recent years, and there are no primary scandium mines in the world at present. Production primarily occurs as a by-product from existing metallurgical
plants, primarily in Russia, Canada, the Philippines, and China. Our management believes the Elk Creek Project would significantly increase the world’s supply of scandium
trioxide. Although the Company’s market studies indicate a positive outlook for demand, there is no assurance at present that the Company could sell all of its production. In
addition,  the  sale  of  scandium  represents  a  significant  portion  of  the  Elk  Creek  Project  revenue;  achieving  the  revenue  projected  in  the  Company’s  studies  is  subject  to
market growth in scandium, which is a developing market with a risk of oversupply and/or undersupply disrupting pricing.

Titanium metal is used in various superalloys and other applications for aerospace applications, armor, and medical implants, and in oxide form is a key component of
pigments used in paper, paint, and plastics. The Elk Creek Project would produce a small quantity of titanium dioxide relative to other producers. As a small producer, we
would be subject to fluctuations in the price of TiO2 that would result from normal variations in supply and demand for this commodity.

We may not be able to establish a viable recovery process for REEs.

The market for rare earth products requires particular levels of purity and chemical form, which are achieved through the extraction and separation of individual REEs
from each other as well as from the other constituents in the rare earth ore. At present, the Company has substantially completed the engineering and testing of a process for
producing commercial rare earth products but has not completed all work necessary to declare a REE reserve estimate for the Elk Creek deposit. The completion of the work
necessary to demonstrate an economically feasible rare earth recovery system will require additional expenditures of cash and time to complete. There is no guarantee that
the Company will be successful in demonstrating positive economics for a rare earth recovery system tied to the Elk Creek

18

 
 
 
 
 
 
 
 
 
 
 
Project, nor is there any guarantee that once constructed, the rare earth recovery system will operate as designed and produce saleable commercial products.

Estimates of resources and reserves are subject to evaluation uncertainties that could result in project failure.

Our  exploration  and  future  mining  operations,  if  any,  are  and  would  be  faced  with  risks  associated  with  being  able  to  accurately  predict  the  quantity  and  quality  of
resources/reserves within the earth using statistical sampling techniques. Estimates of any resources/reserves on any of our properties would be made using samples obtained
from  appropriately  placed  trenches,  test  pits,  underground  workings,  and  intelligently  designed  drilling.  There  is  an  inherent  variability  of  assays  between  check  and
duplicate samples taken adjacent to each other and between sampling points that cannot be reasonably eliminated. Additionally, there also may be unknown geologic details
that have not been identified or correctly appreciated at the current level of accumulated knowledge about our properties. This could result in uncertainties that cannot be
reasonably eliminated from the process of estimating resources/reserves. If these estimates were to prove to be unreliable, we could implement an exploitation plan that may
not lead to commercially viable operations in the future.

Any material changes in mineral resource/reserve estimates and grades of mineralization will affect the economic viability of placing a property into production and a
property’s return on capital.

Mineral resource/reserve estimates may require adjustments or downward revisions. In addition, the grade of ore ultimately mined, if any, may differ from that indicated
by  our  feasibility  studies  and  drill  results.  Minerals  recovered  in  small  scale  tests  may  not  be  duplicated  in  large  scale  tests  under  on-site  conditions  or  at  commercial
production scale.

The  resource  and  reserve  estimates  included  in  the  S-K  1300  Elk  Creek Technical  Report  Summary  and  contained  in  this Annual  Report  on  Form  10-K  have  been
determined based on assumed future prices, cut-off grades, and operating costs that may prove to be inaccurate. Extended declines in market prices for our products may
render  portions  of  our  resource/reserve  estimates  uneconomic  and  may  result  in  reduced  reported  resources/reserves  or  may  adversely  affect  any  commercial  viability
determinations we may reach. Any material reductions in estimates of resources/reserves could have a material adverse effect on our Common Share price and on the value
of our properties.

We face intense competition in the mining industry.

The  mining  industry  is  intensely  competitive  in  all  of  its  phases. As  a  result  of  this  competition,  some  of  which  is  with  large  established  mining  companies  with
substantial  capabilities  and  with  greater  financial  and  technical  resources  than  ours,  we  may  be  unable  to  acquire  additional  properties,  if  any,  or  financing  on  terms  we
consider acceptable. We also compete with other mining companies in the recruitment and retention of qualified managerial and technical employees. If we are unable to
successfully  compete  for  qualified  employees,  our  exploration  and  development  programs  may  be  slowed  down  or  suspended.  We  compete  with  other  companies  that
produce our planned commercial products for capital. If we are unable to raise sufficient capital, our exploration and development programs may be jeopardized or we may
not be able to acquire, develop, or operate additional mining projects.

Difficulties in water balance management at our Elk Creek Project could negatively affect our potential production and economics at the project.

The  Company  has  conducted  three  field  investigations  and  two  major  technical  studies  into  the  hydrogeology  of  the  Elk  Creek  carbonatite,  which  is  the  geologic
formation which hosts the mineralized material that would be extracted by the Company’s mining operations. The Company expects to encounter significant amounts of
water in the carbonatite, which will need to be pumped out of the formation to facilitate a mining operation. Water quality analyses have demonstrated that this water will
have elevated temperature and salt content when compared to other water resources in the area. While the Company has developed plans to treat water produced from the
mine for use in its operations, there is no guarantee that the permits needed for the treatment of the water or the disposal of the resultant waste products will be issued by the
State of Nebraska, nor is there any guarantee that such permits will be issued in a timely fashion. Further, based on such plans, the operations will rely on a water treatment
system to achieve zero discharge of wastewater, and there is no guarantee that this system will function as designed or achieve nameplate treatment capacity.

19

 
 
 
 
 
 
 
 
 
 
 
 
Title to our properties may be subject to other claims that could affect our property rights and claims.

There  are  risks  that  title  to  our  properties  may  be  challenged  or  impugned.  Our  Elk  Creek  Project  is  located  in  Nebraska  and  may  be  subject  to  prior  unrecorded
agreements or transfers or native land claims, and title may be affected by undetected defects. Our current land and/or mineral rights lease agreements between ECRC and
individual landowners give us an option to purchase additional property (“OTP”), which, along with the property we already own, will allow us to construct the Elk Creek
Project  once  sufficient  project  financing  is  obtained. The  rights  of  the  current  owners  to  sell  the  property  subject  to  these  options  may  be  subject  to  prior  unrecorded  or
unknown  claims  to  title.  We  have  investigated  our  rights  to  explore  and  exploit  the  Elk  Creek  Project  resource/reserve  and,  to  the  best  of  our  knowledge,  our  rights  in
relation  to  lands  covering  the  Elk  Creek  Project  resource/reserve  are  in  good  standing.  However,  there  may  be  valid  challenges  to  the  title  of  our  properties  that,  if
successful, could impair development and/or operations. Further, our current OTP agreements, which are important for operations, are of fixed duration and expire between
December 2024 and May 2040.

Our properties and operations may be subject to litigation or other claims.

From time to time our properties or operations may be subject to disputes that may result in litigation or other legal claims. We may be required to assert or defend
against  these  claims,  which  will  divert  resources  and  management  time  from  operations. The  costs  of  these  claims  or  adverse  filings  may  have  a  material  effect  on  our
business and results of operations.

We do not currently insure against all the risks and hazards of mineral exploration, development, and mining operations.

Exploration,  development,  mining,  and  surface  operations  involve  various  hazards,  including  environmental  hazards,  industrial  accidents,  metallurgical  and  other
processing problems, unusual or unexpected rock formations, structural cave-ins or slides, flooding, fires, and periodic interruptions due to inclement or hazardous weather
conditions.  These  risks  could  result  in  damage  to  or  destruction  of  mineral  properties,  facilities,  or  other  property,  personal  injury,  environmental  damage,  delays  in
operations, increased cost of operations, monetary losses, and possible legal liability. We may not be able to obtain insurance to cover these risks at economically feasible
premiums or at all. We may elect not to insure where premium costs are disproportionate to our perception of the relevant risks. The payment of such insurance premiums
and of such liabilities would reduce the funds available for exploration and production activities.

Risks Related to Government Regulation

We may not be able to obtain or renew all required permits and licenses to place any of our properties into production.

Our  current  and  future  operations,  including  development  activities  and  commencement  of  production,  if  warranted,  on  the  Elk  Creek  Project,  require  permits  from
governmental  authorities  and  such  operations  are  and  will  be  governed  by  laws  and  regulations  governing  prospecting,  development,  mining,  production,  exports,  taxes,
labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety, and other matters. Companies engaged in mineral
property  exploration  and  the  development  or  operation  of  mines  and  related  facilities  generally  experience  increased  costs,  as  well  as  delays  in  production  and  other
schedules as a result of the need to comply with applicable laws, regulations, and permits. We cannot predict if all permits that we may require for continued exploration,
development, or construction of mining facilities and conduct of mining operations will be obtainable or renewable on reasonable terms, if at all. Costs related to applying
for  and  obtaining  permits  and  licenses  may  be  prohibitive  and  could  delay  our  planned  exploration  and  development  activities.  Failure  to  comply  with  applicable  laws,
regulations, and permitting requirements may result in enforcement actions, including orders issued by regulatory or judicial authorities causing operations to cease or be
curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, or remedial actions.

Facilities  associated  with  the  Elk  Creek  Project,  such  as  the  mine,  surface  plant,  tailings  facilities,  stockpiles  and  supporting  infrastructure,  are  likely  to  either
temporarily or permanently impact waterbodies and wetlands that are subject to regulation by the USACE as Waters of the United States (“WOUS”). We believe that we
have obtained the necessary USACE permits to construct the project, but changes to the design or layout of the facility may trigger the

20

 
 
 
 
 
 
 
 
 
 
 
 
USACE to require us to obtain and maintain additional permits for the Elk Creek Project. The duration of this permitting exercise is dictated by the USACE and would need
to be completed before facilities that would impact WOUS could be constructed. We may experience delays or additional costs in relation to obtaining the necessary permits
and these delays and additional costs could negatively affect the economics of the Elk Creek Project and our results of operations.

Parties engaged in mining operations may be required to compensate those suffering loss or damage by reason of the mining activities and may have civil or criminal
fines  or  penalties  imposed  for  violations  of  applicable  laws  or  regulations. Amendments  to  current  laws,  regulations,  and  permits  governing  operations  and  activities  of
mining  companies,  or  more  stringent  implementation  thereof,  could  have  a  material  adverse  impact  on  our  operations  and  cause  increases  in  capital  expenditures  or
production costs or reduction in levels of production at producing properties or require abandonment or delays in development of new mining properties.

We are subject to significant governmental regulations that affect our operations and costs of conducting our business.

Our current and future operations, including development of the Elk Creek Project, are and will be governed by laws and regulations, including:

● laws and regulations governing mineral concession acquisition, prospecting, development, mining, and production;
● laws and regulations related to exports, taxes, and fees;
● labor standards and regulations related to occupational health and mine safety; and
● environmental standards and regulations related to waste disposal, toxic substances, land use reclamation, and environmental protection.

Companies  engaged  in  development  activities  often  experience  increased  costs  and  delays  in  production  and  other  schedules  as  a  result  of  the  need  to  comply  with
applicable laws, regulations, and permits. Failure to comply with applicable laws, regulations, and permits may result in enforcement actions, including the forfeiture of
mineral claims or other mineral tenures and/or orders issued by regulatory or judicial authorities requiring operations to cease or be curtailed, and may include corrective
measures requiring capital expenditures, installation of additional equipment, or costly remedial actions. We may be required to compensate those suffering loss or damage
by reason of our development activities and may have civil or criminal fines or penalties imposed for violations of such laws, regulations, and permits.

Existing and possible future laws, regulations, and permits governing operations and activities of mineral development companies, or more stringent implementation,
could have a material adverse impact on our business and cause increases in capital expenditures or require abandonment or delays in development. Our Elk Creek Project is
located  in  Nebraska,  and  while  the  State  does  have  a  comprehensive  and  modern  set  of  environmental  regulations,  it  does  not  have  specific  regulations  with  respect  to
permitting or reclaiming mines which could potentially impact the total time to market for the project.

Our activities are subject to environmental laws and regulations that may change, thereby increasing our costs of doing business and restricting our operations.

All phases of our operations are subject to environmental regulation in the jurisdictions in which we operate. Environmental legislation is evolving in a manner that may
require  stricter  standards  and  enforcement,  increased  fines  and  penalties  for  non-compliance,  more  stringent  environmental  assessments  of  proposed  projects,  and  a
heightened degree of responsibility for companies and their officers, directors, and employees. These laws address emissions into the air, discharges into water, management
of waste, management of hazardous substances, protection of natural resources, antiquities and endangered species, and reclamation of lands disturbed by mining operations.
Compliance  with  environmental  laws  and  regulations,  and  future  changes  in  these  laws  and  regulations,  may  require  significant  capital  outlays  and  may  cause  material
changes  or  delays  in  our  operations  and  future  activities.  It  is  possible  that  future  changes  in  these  laws  or  regulations  could  have  a  significant  adverse  impact  on  our
properties or some portion of our business, causing us to re-evaluate those activities at that time.

21

 
 
 
 
 
 
 
 
 
 
 
Regulations and pending legislation governing issues involving climate change could result in increased operating costs, which could have a material adverse effect on
our business.

A  number  of  governments  or  governmental  bodies  have  introduced  or  are  contemplating  legislative  and/or  regulatory  changes  in  response  to  concerns  about  the
potential impact of climate change. Legislation and increased regulation regarding climate change could impose significant costs on us, on our future venture partners, if any,
and  on  our  suppliers,  including  costs  related  to  increased  energy  requirements,  capital  equipment,  environmental  monitoring  and  reporting,  and  other  costs  necessary  to
comply  with  such  regulations. Any  adopted  future  climate  change  regulations  could  also  negatively  impact  our  ability  to  compete  with  companies  situated  in  areas  not
subject to such limitations. Given the emotion, political significance, and uncertainty surrounding the impact of climate change and how it should be dealt with, we cannot
predict  how  legislation  and  regulation  will  affect  our  financial  condition,  operating  performance,  and  ability  to  compete.  Furthermore,  even  without  such  regulation,
increased awareness and any adverse publicity in the global marketplace about potential impacts on climate change by us or other companies in our industry could harm our
reputation. The potential physical impacts of climate change on our operations are highly uncertain and could be particular to the geographic circumstances in areas in which
we  operate  and  may  include  changes  in  rainfall  and  storm  patterns  and  intensities,  water  shortages,  changing  sea  levels,  and  changing  temperatures. These  impacts  may
adversely impact the cost, production, and financial performance of our operations.

Land reclamation requirements for our properties may be burdensome and expensive.

Although variable depending on location and the governing authority, land reclamation requirements are generally imposed on mineral exploration companies (as well

as companies with mining operations) in order to minimize long-term effects of land disturbance.

Reclamation may include requirements to:

● control dispersion of potentially deleterious effluents;
● treat ground and surface water to achieve water quality standards; and
● reasonably re-establish pre-disturbance landforms and vegetation.

In order to carry out reclamation obligations imposed on us in connection with our potential development activities, we must allocate financial resources that might
otherwise be spent on further exploration and development programs. We plan to set up a provision for our reclamation obligations on our properties, as appropriate, but this
provision may not be adequate. If we are required to carry out unanticipated reclamation work, our financial position could be adversely affected.

Risks Related to Our Debt

The level of our indebtedness from time to time could impair our ability to obtain additional financing.

From time to time, we may enter into transactions to acquire assets or the shares of other companies or to fund development of the Elk Creek Project. These transactions
may  be  financed  partially  or  wholly  with  debt,  which  may  increase  our  debt  levels  above  industry  standards.  Our  articles  of  incorporation  do  not  limit  the  amount  of
indebtedness  that  we  may  incur.  Our  indebtedness  could  impair  our  ability  to  obtain  additional  financing  in  the  future  on  a  timely  basis  to  take  advantage  of  business
opportunities that may arise. Our ability to service our debt obligations will depend on our future operations, which are subject to prevailing industry conditions and other
factors, many of which are beyond our control.

Risks Related to the Common Shares

NioCorp may be a “passive foreign investment company” for the current taxable year and for one or more future taxable years, which may result in materially

adverse U.S. federal income tax consequences for U.S. investors.

If NioCorp is a passive foreign investment company (“PFIC”) for any taxable year, or portion thereof, that is included in the holding period of a U.S. holder of Common

Shares or other securities of NioCorp, such U.S. holder

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
may be subject to certain adverse U.S. federal income tax consequences. These adverse tax consequences include requirements to treat any gain realized upon a disposition
of Common Shares or other securities, or any “excess distribution” received on Common Shares, as ordinary income, to pay an interest charge on a portion of such gain or
distribution, and certain additional reporting requirements. Such consequences may be mitigated with respect to Common Shares (but not with respect to warrants or other
securities  of  NioCorp)  if  the  holder  thereof  makes  a  timely  and  effective  “qualified  electing  fund”  or  “QEF”  election  or  a  “mark-to-market”  election. A  U.S.  holder  of
Common Shares that makes a QEF election generally must include in income on a current basis for U.S. federal income tax purposes its share of NioCorp’s net capital gain
and ordinary earnings for any taxable year in which it is a PFIC, whether or not NioCorp distributes any amount to its shareholders. A U.S. holder of Common Shares that
makes a mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer’s basis
therein.

NioCorp generally will be classified as a PFIC for a taxable year if (a) 75% or more of its gross income for such year is “passive income” (generally, dividends, interest,
rents,  royalties,  and  gains  from  the  disposition  of  assets  producing  passive  income)  or  (b)  at  least  50%  or  more  of  the  value  of  its  assets  produce,  or  are  held  for  the
production of, passive income, based on the quarterly average of the fair market value of such assets. NioCorp believes that it may be classified as a PFIC for its taxable year
ended June 30, 2023 and was classified as a PFIC for its taxable year ended June 30, 2022 and, based on the current composition of its income and assets, as well as current
business plans and financial expectations, may be classified as a PFIC for future taxable years. Any conclusion regarding PFIC status is a factual determination that must be
made annually at the close of each taxable year and, thus, is subject to change. In addition, even if NioCorp concluded it did not qualify as a PFIC, it is possible that the U.S.
Internal  Revenue  Service  (the  “IRS”)  could  assert,  and  that  a  court  could  sustain,  a  determination  that  NioCorp  is  a  PFIC. Accordingly,  there  can  be  no  assurance  that
NioCorp will not be treated as a PFIC for any taxable year. The PFIC rules are complex and each holder of Common Shares or other securities of NioCorp should consult its
own tax advisors regarding these rules and the U.S. federal income tax consequences of the acquisition, ownership, and disposition of such securities.

The Transactions could result in NioCorp becoming subject to materially adverse U.S. federal income tax consequences.

Section 7874 and related sections Code, provide for certain adverse tax consequences when the stock of a U.S. corporation is acquired by a non-U.S. corporation in
certain transactions in which former shareholders of the U.S. corporation come to own 60% or more of the stock of the non-U.S. corporation (by vote or value, and applying
certain  specific  counting  and  ownership  rules).  These  adverse  tax  consequences  include  (i)  potential  additional  required  gain  recognition  by  the  U.S.  corporation,  (ii)
treatment  of  certain  payments  to  the  non-U.S.  corporation  that  reduce  gross  income  as  “base  erosion  payments,”  (iii)  an  excise  tax  on  certain  options  and  stock-based
compensation of the U.S. corporation, (iv) disallowance of “qualified dividend” treatment for distributions by the non-U.S. corporation, and (v) if former shareholders of the
U.S. corporation come to own 80% or more of the stock of the non-U.S. corporation, treatment of the non-U.S. corporation as a U.S. corporation subject to U.S. federal
income tax on its worldwide income (in addition to any tax imposed by non-U.S. jurisdictions). If the Transactions result in the application of any of these, or any other,
adverse  tax  consequences,  NioCorp  could  incur  significant  additional  tax  costs.  While  NioCorp  currently  does  not  believe  the  Transactions  will  cause  such  adverse  tax
consequences as a result of Section 7874 and related sections of the Code, this determination is subject to significant legal and factual uncertainty. NioCorp has not sought
and will not seek any rulings from the IRS as to the tax treatment of any of the Transactions. Further, there can be no assurance that your tax advisor, the IRS, or a court, will
agree with the position that NioCorp is not subject to these adverse tax consequences.

Our Common Share price may be volatile and as a result you could lose all or part of your investment.

In addition to volatility associated with equity securities in general, the value of your investment could decline due to the impact of any of the following factors upon the

market price of the Common Shares:

● disappointing results from our exploration and/or, if warranted, project development efforts;
● decline in demand for Common Shares;
● downward revisions in securities analysts’ estimates or changes in general market conditions;
● technological innovations by competitors or in competing technologies;
● investor perception of our industry or our prospects; and
● general economic trends.

In  addition,  stock  markets  in  general  have  experienced  extreme  price  and  volume  fluctuations,  and  the  market  prices  of  securities  have  been  highly  volatile.  These
fluctuations  are  often  unrelated  to  operating  performance  and  may  adversely  affect  the  market  price  of  the  Common  Shares. As  a  result,  you  may  be  unable  to  sell  any
Common Shares you acquire at a desired price.

We have never paid dividends on the Common Shares.

We have not paid dividends on the Common Shares to date, and we may not be in a position to pay dividends for the foreseeable future. Our ability to pay dividends
with respect to the Common Shares will depend on our ability to successfully develop one or more properties and generate earnings from operations. Further, our initial
earnings,  if  any,  will  likely  be  retained  to  finance  our  operations. Any  future  dividends  on  Common  Shares  will  depend  upon  our  earnings,  our  then-existing  financial
requirements, and other factors, and will be at the discretion of our Board of Directors.

Future  sales,  or  the  perception  of  future  sales,  of  Common  Shares  by  existing  shareholders  or  by  us,  or  future  dilutive  issuances  of  Common  Shares  by  us,  could
adversely affect prevailing market prices for the Common Shares and cause investors to suffer dilution in their net book value per Common Share.

Sales of a substantial number of Common Shares in the public market could occur at any time, including issuances and sales of additional Common Shares by us and
sales  by  other  security  holders.  These  sales,  or  the  market  perception  that  the  holders  of  a  large  number  of  Common  Shares  or  securities  convertible,  exercisable,  or
exchangeable into Common Shares intend to sell Common Shares, could reduce the prevailing market price of the Common Shares. The effect, if any, that future public
sales of these securities or the availability of these securities for sale will have on the market price of the Common Shares is uncertain. If the market price of the Common
Shares were to drop as a result, this might impede our ability to raise additional capital and might cause remaining shareholders to lose all or part of their investment.

The Articles of NioCorp, as amended in connection with the Transactions, permit us to issue an unlimited number of Common Shares. Subject to the requirements of the
British Columbia Business Corporations Act, Nasdaq and TSX, we will not be required to obtain the approval of the NioCorp shareholders for the issuance of additional
Common  Shares. We  have  issued  Common  Shares  in  the  past  and  will  continue  to  issue  Common  Shares  to  finance  our  activities  in  the  future.  In  addition,  outstanding
options,  warrants,  and  broker  warrants  to  purchase  Common  Shares  may  be  exercised,  resulting  in  the  issuance  of  additional  Common  Shares.  If  we  issue  additional
Common Shares or decide to enter into joint ventures with other parties in order to raise financing through the sale of equity securities, investors’ interests in the Company
will be diluted and investors may suffer dilution in their net book value per Common Share depending on the price at which such securities are sold.

Additionally, pursuant to the Yorkville Equity Facility Financing Agreement, Yorkville has committed to purchase up to $65.0 million of our Common Shares, at our
direction from time to time during the Commitment Period, subject to certain limitations and the satisfaction of the conditions in the Yorkville Equity Facility Financing
Agreement. We have filed a registration statement under the Securities Act covering resales by Yorkville of the Common Shares issuable pursuant to the Yorkville Equity
Facility Financing Agreement. Accordingly, any Common Shares that we issue pursuant to the Yorkville Equity Facility Financing Agreement will be available for sale into
the public market, subject to applicable securities laws, which could reduce the prevailing market price for the Common Shares.

24

 
  
 
 
 
 
 
 
 
 
 
We are subject to the continued listing criteria of the Nasdaq and TSX and our failure to satisfy these criteria may result in delisting of the Common Shares.

Our Common Shares are currently listed on the Nasdaq Global Market and TSX under the symbol “NB”. The public NioCorp Assumed Warrants are currently listed on
the Nasdaq Capital Market under the symbol “NIOBW.” Both the Nasdaq Capital Market and TSX have rules for continued listing. In order to maintain the listings, we must
maintain certain financial and share distribution targets, including maintaining a minimum number of public shareholders. In addition to objective standards, TSX may delist
the  securities  of  any  issuer  if,  in  TSX’s  opinion,  the  issuer’s  financial  condition  and/or  operating  results  appear  unsatisfactory;  if  it  appears  that  the  extent  of  public
distribution or the aggregate market value of the security has become so reduced as to make continued listing on TSX inadvisable; if the issuer sells or disposes of principal
operating assets or ceases to be an operating company; if an issuer fails to comply with the listing requirements of TSX; or if any other event occurs or any condition exists
which makes continued listing on TSX, in the opinion of TSX, inadvisable.

If  Nasdaq  or  TSX  delists  the  Common  Shares,  investors  may  face  material  adverse  consequences,  including,  but  not  limited  to,  a  lack  of  a  trading  market  for  the
Common Shares, reduced liquidity, a determination that our Common Shares are a “penny stock,” decreased analyst coverage of the Company, and an inability for us to
obtain additional financing to fund our operations.

The issuance of additional Common Shares may negatively impact the trading price of our securities.

We have issued Common Shares in the past and will continue to issue Common Shares to finance our activities in the future. In addition, outstanding options, warrants,
and  broker  warrants  to  purchase  Common  Shares  may  be  exercised,  resulting  in  the  issuance  of  additional  Common  Shares. The  issuance  by  us  of  additional  Common
Shares  would  result  in  dilution  to  our  shareholders,  and  even  the  perception  that  such  an  issuance  may  occur  could  have  a  negative  impact  on  the  trading  price  of  the
Common Shares.

If  our  Common  Shares  are  considered  a  penny  stock  and  are  subject  to  the  penny  stock  rules,  broker-dealers  may  be  discouraged  from  effecting  transactions  in
Common Shares.

Our Common Shares has in the past, and may in the future, be considered a “penny stock.” The SEC has adopted Rule 15g-9 which generally defines “penny stock” to
be any equity security that has a market price (as defined) less than $5.00 per share or an exercise price of less than $5.00 per share, subject to certain exceptions. Applicable
penny stock rules impose additional sales practice requirements on broker-dealers who sell to persons other than established customers and “accredited investors.” The term
“accredited  investor”  refers  generally  to  institutions  with  assets  in  excess  of  $5.0  million  or  individuals  with  a  net  worth  in  excess  of  $1.0  million  or  annual  income
exceeding $200 or $300, jointly with their spouse. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules,
to deliver a standardized risk disclosure document in a form prepared by the SEC, which provides information about penny stocks and the nature and level of risks in the
penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and
its  salesperson  in  the  transaction,  and  monthly  account  statements  showing  the  market  value  of  each  penny  stock  held  in  the  customer’s  account.  The  bid  and  offer
quotations, and the broker-dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be
given  to  the  customer  in  writing  before  or  with  the  customer’s  confirmation.  In  addition,  the  penny  stock  rules  require  that  prior  to  a  transaction  in  a  penny  stock  not
otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive
the purchaser’s written agreement to the transaction. If and when applicable, these disclosure requirements may have the effect of reducing the level of trading activity in the
secondary market for the Common Shares. Consequently, these penny stock rules may affect the ability of broker-dealers to trade in the Common Shares.

Property Description and Location

The  Elk  Creek  Property  is  a  carbonatite  deposit  located  in  Johnson  County,  southeast  Nebraska,  USA. The  carbonatite  contains  elements  of  economic  significance,
including niobium, titanium, and scandium, as well as potential economic significance for rare earth products. The Elk Creek Property is situated as shown below and is
located  within  the  USGS Tecumseh  Quadrangle  Nebraska  SE  (7.5  minute  series)  mapsheet  in  Sections  1-6,  9-11; Township  3N;  Range  11E  and  Sections  19-23,  25-36;
Township  4N,  Range  11E,  at  approximately  40°16’  north  and  96°11’  west  in  the  State  of  Nebraska,  in  central  USA. The  Elk  Creek  Property  is  approximately  45  miles
southeast of Lincoln, Nebraska, the state capital of Nebraska.

Title and Ownership

Land in the project area is exclusively owned by private entities, and there is no federal or state land in the project area. The Company has secured its rights to the

project area by purchasing land from private landowners or by entering into agreements with the landowners as described below.

The  Company  currently  owns  one  approximately  225-acre  parcel  of  land  and  associated  mineral  rights,  and  an  additional  40  acres  of  mineral  rights,  within  the
carbonatite footprint. The Elk Creek Project’s mine infrastructure and a portion of the supporting operations is planned to be located on this land parcel. Ownership of the
mineral rights discussed above includes a 2% NSR royalty and grants us access to more than 90% of the Elk Creek Project’s mineral resources and mineral reserves.

As of June 30, 2023, the total book value of the Elk Creek Property and associated buildings and equipment was $16.9 million.

The Company also holds eight OTPs that are associated with the Elk Creek Project and one perpetual easement of a land parcel along the Missouri River. The current
optioned land package covers an area of 1,396 acres and is reflective of the land needed to secure the remaining mineral resources and mineral reserves held under the OTPs
along with the land needed for the development and operations of the Elk Creek Project for its proposed 38-year operating life.

In general, exercise of an OTP is accomplished by paying the greater of a fixed amount per acre or a multiple of the appraised value at the time of purchase. If the land
is not purchased by the Company during the term of the OTP and the land in question is needed for the project, the Company will negotiate a new OTP with the landowner.
The OTP is accompanied by a negotiated payment to the landowner that is paid upon execution of the OTP by the Company and the landowner. As of June 30, 2023, the
Company is obligated to make payments totalling approximately $45,000 over the next 12 years to maintain our rights under these OTPs. Details on the current OTPs held
by the Company are shown in the table below.

The  OTPs  are  between  NioCorp’s  subsidiary  ECRC  and  the  individual  landowners.  Land  subject  to  the  OTP  agreements  is  currently  used  for  agricultural  purposes,
including growing row crops (corn and soybeans) and pasturing livestock. The land owned by ECRC houses the company drill core and geological sample repository in two
steel core shed buildings and the company maintains a cover crop (sorghum and rye) on portions of the property that were formerly used for growing row crops. The former
landowner maintains a residence and several outbuildings on the property subject to a life estate that accompanied the purchase of the property by the Company in fiscal year
2021.

The agreements that involve mineral rights include a 2% NSR royalty attached with the OTP. The OTPs grant the Company an exclusive right to explore and evaluate
the  property  for  the  term  thereof,  with  an  option  to  purchase  the  surface  rights  or  a  combination  of  the  mineral  and  surface  rights  at  any  time  during  the  term. As  the
Woltemath80S agreement is limited to an option to purchase the surface rights only, it does not contain an NSR provision.

Land Tenure Map as of October 2023

The current estimated mineral resource and reserve is wholly contained within land owned by the Company and parcel Woltemath003J. The Company considers these

two properties to be the only properties on which the Company’s development of the Elk Creek Project is substantially dependent.

As  part  of  the  OTPs,  where  required,  the  Company  has  also  secured  surface  rights,  which  allow  for  access  to  the  land  for  drilling  activities  and  associated  mineral

exploration and project development work.

Accessibility, Physiography, Climate and Infrastructure

The Elk Creek Property is easily accessible year-round as it is situated approximately 45 miles southeast of Lincoln, Nebraska, the state capital, and approximately 68
miles south of Omaha, Nebraska. Access to the site can be completed via road or from one of the regional airports. There are several regular flights to both Lincoln and
Omaha; however, the Elk Creek Property is most easily accessible from Lincoln. From Lincoln Municipal Airport, the Elk Creek Property is accessed via paved roads on the
main network and a secondary network of gravel roads. The drive from the Lincoln Municipal Airport to the property is typically 1 hour and 15 minutes, and from Omaha’s
Eppley Airport, the drive is approximately 1 hour and 45 minutes.

The Elk Creek Property is immediately adjacent to paved Nebraska state highway 50, and the mineral resource and mineral reserve are centered in Township 4N, Range
11E, Section 33. This section is immediately southwest of the junction of Nebraska state highways 50 and 62. Rail access is available in the town of Elk Creek, which is
located 3 miles east of the project area. Water is available at the project site from a well, as well as from Elk Creek, which crosses Section 33. Water is also available from
the Johnson County Rural Water system, which has distribution infrastructure on the north side of the Section 33 and from the Pawnee County Rural Water system, which
has distribution infrastructure on the south side of Section 33. Electricity is provided at the Company’s Core Storage sheds located on the west side of Section 33 on land
owned by the Company from the Omaha Public Power District (“OPPD”). Personnel are available from the local surrounding towns, including Elk Creek (3 miles east),
Tecumseh

28

 
 
 
 
 
 
 
 
 
 
(6 miles north), Steinauer (5 miles south), Pawnee City (10 miles south) and Syracuse (20 miles north). Due to the project’s location in Nebraska, there are no ports nearby.

Southeast  Nebraska  is  situated  in  a  humid  continental  climate  (Dfa)  on  the  Köppen  climate  classification  system.  In  eastern  Nebraska,  this  climate  is  generally
characterized by hot humid summers and cold winters. Average winter temperatures vary between 13°F to 35°F. Average summer temperatures vary between 64°F to 90°F.
Exploration, construction and operational activities may be conducted all year round.

Average monthly precipitation (rain and snowfall) varies between 0.9 and 5.0 inches. Average yearly precipitation is between 31 and 33 inches with an average yearly
snowfall of approximately 28 inches. Nebraska is located within an area known for tornadoes which runs through the central U.S. where thunderstorms are common in the
spring and summer months. Tornadoes primarily occur during the spring and summer and may occur into the autumn months.

There are several local communities near the Elk Creek Property, including Elk Creek and Tecumseh, that will provide local housing for the Elk Creek Project. There
are a number of other communities within driving distance and the large cities of Lincoln and Omaha are within reasonable driving distance. Mining activities currently
taking place in the area are limited to limestone and aggregate operations to support the local cement manufacturing and construction industries.

The Elk Creek Project is expected to incorporate surface and underground infrastructure, as well as tailings storage facilities. The offsite infrastructure is expected to
include a new high voltage transmission line constructed by the local utility company and providing power to an on-site primary sub-station and a natural gas pipeline built
by the owner of the interstate pipeline. Water used for all on-site process needs and activities will be supplied from mine dewatering activities, local groundwater wells and
from a local water utility. See “2022 Elk Creek Feasibility Study” below for additional information regarding proposed infrastructure related to the Elk Creek Project.

The local topography of eastern Nebraska is relatively low-relief with shallow rolling hills intersected by shallow river valleys. Elevation varies from about 1,066 to

1,280 ft above sea level. Bedrock outcrop exposure is nonexistent in the Elk Creek Project area.

The majority of the area around the Elk Creek Project is used for cultivation of corn and soybeans, along with uses as grazing land. Native vegetation typical of eastern

Nebraska is upland tall-grass, prairie and upland deciduous forests.

Geology and Mineralization

Geology

The Elk Creek Property includes a carbonatite that has intruded older Precambrian granitic and low- to medium-grade metamorphic basement rocks. The carbonatite is
an elliptical magmatic body with a northwest-trending long axis perpendicular to the strike of the Midcontinent Rift System, near the northern part of the Nemaha uplift. The
carbonatite consists predominantly of dolomite, calcite and ankerite, with lesser chlorite, barite, phlogopite, pyrochlore, serpentine, fluorite, sulfides, bastnasite, monazite,
and  quartz.  It  is,  however,  believed  from  stratigraphic  reconstruction  based  on  drill  core  observation  in  the  area  that  the  carbonatite  is  unconformably  overlain  by
approximately 200 m of essentially flat-lying Palaeozoic marine sedimentary rocks, including carbonates, sandstones and shales of Pennsylvanian age.

Mineralization

The  property  hosts  niobium,  titanium,  and  scandium  mineralization  as  well  as  REE  mineralization  that  occurs  within  the  Elk  Creek  carbonatite. The  current  known
extents of the carbonatite unit are approximately 950 m along strike, 300 m wide, and 750 m in dip extent, below the unconformity. Niobium, titanium, scandium, and rare
earths are considered the main elements of interest.

The  deposit  contains  significant  concentrations  of  niobium.  Based  on  the  metallurgical  testwork  completed  to  date  at  a  number  of  laboratories  using  QEMSCAN®

analysis, the niobium mineralization is known to be fine grained,

29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
and that 77% of the niobium occurs in the mineral pyrochlore, while the balance occurs in an iron-titanium-niobium oxide mineral of varying composition.

Within the Elk Creek carbonatite, a host of other elements exist with varying degrees of concentration. The Company has completed both whole rock analysis and multi-

element analysis on all samples for the 2014 drilling program, described below, plus resampling of selected historical core/pulps between 2011 and 2014.

Historical Exploration

Drilling at the Elk Creek Property was conducted in three phases. The first was during the 1970’s and 1980’s by the Molybdenum Company of America (“Molycorp”),
the second in 2011 by Quantum Rare Earth Developments Corp (“Quantum” - NioCorp under its former name), and the third and latest program from 2014 to 2016 by
NioCorp. To date, 129 diamond core holes have been completed for a total of 64,981 m over the entire geological complex. Of these, a total of 48 holes (33,909 m) have
been completed to date in the mineralized area and are used in the current mineral resource and reserve estimates. Five additional holes, with a total length of 3,353.1 m,
were drilled for hydrogeologic and geotechnical purposes in 2015. No sampling has been completed of these five holes to date and therefore they have not been considered
for the mineral resource or reserve estimates.

All drilling has been completed using a combination of Tricone, Reverse Circulation (“RC”) or Diamond Drilling (“DDH”) in the upper portion of the hole within the

Pennsylvanian sediments. All drilling within the underlying carbonatite has been completed using DDH methods.

Between 1973 and 1974, Molycorp completed six drillholes: EC-1 to EC-4, targeting the Elk Creek anomaly, and two other holes outside the Elk Creek anomaly area.

Drillholes were typically carried out by RC drilling through the overlying sedimentary rocks and diamond drilling through the Ordovician-Cambrian basement rocks.

Molycorp  continued  their  drill  program  from  1977  and,  in  May  1978,  Molycorp  made  its  discovery  of  the  current  mineral  resource  with  drillhole  EC-11.  EC-11  is

located on Section 33, Township 4N, and Range 11. The carbonatite hosting the Elk Creek Project was intersected at a vertical depth of 203.61 m (668 ft).

Molycorp continued its drilling program through to 1984, which mainly centered on the Elk Creek Project within a radius of roughly 2 km. By 1984, Molycorp had

completed 57 drillholes within the Elk Creek gravity anomaly area, which included 25 drillholes over the Elk Creek Project area.

From 1984 to 1986, drilling was focused on the Elk Creek gravity anomaly area. The anomaly area is roughly 7 km in diameter and drilling was conducted on a grid

pattern of approximately 610 m by 610 m (roughly 2,000 ft by 2,000 ft) with some closer spaced drillholes in selected areas.

By 1986, a total of 106 regional drillholes were completed for a total of approximately 46,797 m (153,532 ft). The deepest hole reached a depth of 1,038 m (3,406 ft)

and bottomed in carbonatite.

Quantum, 2010-2011

In April 2011, Quantum conducted a preliminary drill program (three holes) on the Elk Creek deposit and two REE exploration targets (two holes), which have been
excluded  from  the  current  mineral  resource  and  reserve  estimation,  as  they  do  not  intersect  the  Nb2O5  anomaly  and  are  located  to  the  east.  The  objectives  of  the  drill
program

over the Elk Creek Property were to verify the presence of higher-grade niobium mineralization at depth, and to infill drill the known niobium deposit in order to upgrade the
resource  category  of  the  previous  resource  estimate  and  expand  the  known  resource.  The  drill  program  was  also  established  to  collect  sufficient  sample  material  for
metallurgical characterization and process development studies of the niobium mineralization.

The 2011 program consisted of five inclined drillholes, totaling 3,420 m of NQ size diameter core. Inclusive of this total, three drillholes, totaling 2,318 m, were drilled

into the known Elk Creek deposit.

NioCorp, 2014 to Present

NioCorp  commenced  drilling  on  the  Elk  Creek  Property  using  a  three-phased  program.  The  three-phased  program  was  originally  based  on  14  drillholes  for
approximately 12,150 m (announced in a press release on April 29, 2014), but was subsequently expanded during the program to 18 drillholes for approximately 15,482 m.
Three  of  the  18  drillholes  were  drilled  for  the  purpose  of  metallurgical  characterization  and  process  development  studies.  Two  of  these  drillholes,  NEC14-MET-01  and
NEC14-MET-02, were not assayed, while NEC14-MET-03 was quarter cored with one quarter being assayed and the remainder used for metallurgical testwork. The drilling
has  been  orientated  to  intersect  the  geological  model  from  the  southwest  and  northeast  (perpendicular  to  the  strike),  with  the  exception  of  NEC14-011  and  NEC14-012,
which were oriented southeast and northwest, respectively.

During  fiscal  year  2022,  NioCorp  collected  a  total  of  1,095  samples  originating  from  18  diamond  drill  holes  completed  by  MolyCorp,  as  discussed  above.  These
samples were collected, and subsequently assayed, in order to fill in gaps in our records regarding REE grades and tonnage that may exist in the deposit. Assaying was
conducted at Actlabs in Ancaster, Ontario. The assay results were subjected to a Quality Assurance and Quality Control (“QA/QC”) program consistent with industry best
practices.

A list of the drillholes, sample storage location, and number of assay results, related to the records gaps noted above, are presented below and are represented as blue
drillhole  intervals.  Each  sample  represented  a  5-foot  section  of  drill  core. All  of  the  holes  noted  below  were  drilled  into  the  Elk  Creek  carbonatite  in  the  vicinity  of  the
mineral resource for the Elk Creek Project.

Internal Controls

NioCorp integrated a series of routine QA/QC procedures throughout the sampling and analytical analysis for drilling programs to ensure the highest level of quality
was maintained throughout the process leading to the estimate of mineral reserves and mineral resources for the Elk Creek Project. This included the insertion of duplicate
samples taken from various stages of the process, insertion of known control samples (standard reference materials, certified reference materials (“CRM”), and blanks) and
sending third-party pulps to the secondary lab (SGS Canada Inc.).

Sample  tickets  were  assigned  initially  at  the  core  shed  using  barcodes  with  duplicate  tickets  placed  inside  and  on  the  outside  of  the  bag.  Sample  identification  was
confirmed using barcode labelling and visual sample type comparisons before sample shipment. The use of barcoded samples ensured both shipment forms and analytical
labs used accurate information. Multiple types of QC samples were inserted at this stage of the process, which includes the following:

● Field  quartz  blanks  (1  in  20,  or  5%)  were  inserted  within  or  immediately  after  samples  collected  from  mineralized  intervals,  targeting  zones  of  elevated  visual

mineralization, where possible.

● CRMs (1 in 20, or 5%) were inserted in the field with the sample sequence.

● Field quarter-core duplicates (1 in 20, or 5%) were inserted to test mineralization and sampling variability.

Additional details on the QA/QC program can be found in Section 8 of the S-K 1300 Elk Creek Technical Report Summary.

Mineral deposits, including the Elk Creek deposit, are inherently uncertain because of variability at all scales and sparse sampling. In addition to uncertainty associated

with estimation, there are specific risks and sources of uncertainty associated with the Elk Creek deposit. See Item 1A, Risk Factors.

S-K 1300 and other similarly purposed International Codes (JORC, 2012; NI 43-101, 2014) are designed to require disclosure to the public of risks relating to mineral
resource and reserve estimation as identified and evaluated by a qualified person. The qualified persons responsible for the S-K 1300 Elk Creek Technical Report Summary
address the technical risks in various sections and consider that no material technical risks are identified. Additional descriptions of the risks and uncertainty associated with
reported mineral reserves and resources can be found in Section 11 of the S-K 1300 Elk Creek Technical Report Summary.

2022 Elk Creek Feasibility Study

During fiscal year 2022, the Company launched geological, metallurgical, engineering, and other analyses to assess the feasibility of adding REE production to its plans
once  sufficient  work  has  been  completed.  The  Company  and  its  consultants  were  required  to  complete  additional  assays  of  historical  drill  core  to  fill  data  gaps  in  the
existing resource database to establish an REE mineral resource. The mine plan was also updated and the S-K 1300 Elk Creek Technical Report Summary was filed with the
SEC as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2022. The S-K 1300 Elk Creek Technical Report Summary was based
on  the  economic  and  process  results  of  the  feasibility  study  conducted  by  the  qualified  persons,  which  were  also  presented  in  the  2022  NI  43-101  Elk  Creek Technical
Report.

The Elk Creek Project is planned as an underground mining operation using a long-hole stoping mining method and paste backfill, operating with a processing rate of
2,764 tonnes per day. Expected total production over the 38-year mine life includes 171,140 tonnes of payable niobium, 3,676 tonnes of Sc2O3, and 431,793 tonnes of TiO2.
Estimated up-front direct capital costs are $760 million, in addition to indirect costs of $187 million, pre-production capital costs of $92 million, an overall contingency of
$102 million, and pre-production net revenue credit of $257 million.

Financial Analysis Included in the 2022 Elk Creek Feasibility Study

The metrics reported in the S-K 1300 Elk Creek Technical Report Summary are based on the cash flow model results. The metrics are on both a pre-tax and after-tax
basis,  on  a  100%  equity  basis  with  no  Elk  Creek  Project  financing  inputs  and  are  in  first  quarter  2019  U.S.  constant  dollars.  Foreign  exchange  impacts  were  deemed
negligible as most, if not all, costs and revenues are denominated in U.S. dollars. Key criteria used in the analysis are discussed in detail throughout this section.

Planned Mining Operations

The  Elk  Creek  Project  is  planned  as  an  underground  mining  operation  using  a  long-hole  stoping  mining  method  and  paste  backfill,  with  shaft  access  to  minimize
development through water bearing horizons. The mine will utilize jumbo drills for lateral development and tophammer and down-the-hole drills for vertical development
and production stoping. Rock bolters will be used for ground support and probe holes will be used to support mine grouting where required. Ore will be remotely mucked
from the bottom stope accesses using 14 tonne Load-Haul-Dump units (“LHD”). The LHDs will transport the ore to an ore pass directly or to remuck bays to maximize the
efficiency of the stope mucking operations. When needed, a second LHD and a fleet of 40 tonne haul trucks will be used to transport ore from the remuck bays to the grizzly
feeding the underground material handling system. Multiple remuck bays are used on each level to avoid interference between the LHD and the haul trucks. The ore is fed
through the grizzlys with rock breakers into an underground crusher (the “Primary Crusher”) and via a material handling system to the surface.

Planned Processing Operations

Planned  ore  process  operations  include  mineral  processing,  hydrometallurgical  processing  (“Hydromet”),  and  pyrometallurgical  processing  (“Pyromet”)  housed  in

separate buildings.

35

 
 
 
 
 
 
 
 
 
 
 
 
 
The mineral processing building will house all of its equipment within a single large building. Ore from the Primary Crusher (located in the underground mine) will be
fed to the secondary cone crusher system, operating in closed circuit with a double deck screen. The screen undersize from the cone crusher system will be fed to a high-
pressure grinding roll unit (“HPGR”), operating in closed circuit with another double deck screen. The HPGR screen undersize is the comminution product that will report to
the Hydromet process.

The  Hydromet  plant  building  will  be  a  multi-level  engineered  steel  structure,  which  will  house  equipment  on  two  levels.  Ore  from  mineral  processing  will  be  fed
through 15 individual processes required to separate the three recoverable products. The purpose of the Hydromet processing steps is to leach the pay metals into solution
using two separate acid leaches (Hydrochloric Acid Leach and Sulfuric Acid Bake), remove impurities, separate the three pay metals, and perform precipitation/processing to
final solid oxide forms. Outputs from the Hydromet Process include saleable TiO2 and Sc2O3, with Nb2O5 reporting to the Pyromet plant for final processing. The Hydromet
plant will be supported by a Hydrochloric Acid Regeneration plant and a Sulfuric Acid Plant.

The Pyromet building will house most of its equipment within a single building. The purpose of the Pyromet plant is to reduce the Nb2O5 coming from the Hydromet
plant  by  converting  it  into  a  saleable  FeNb  metal. Aluminum  shots  and  iron  oxide  pellets  will  be  introduced  to  an  electric  arc  furnace  on  a  continuous  basis  along  with
fluxing agents and Nb2O5 to produce a saleable ferroniobium metal.

Proposed Production Plan and Schedule

Based on the 2022 Elk Creek Feasibility Study, the operating mine life is approximately 38 years with a nominal processing rate of 2,764 tonnes per day. The Elk Creek
Project timeline is based on 39 months to mechanical completion after Authorization to Proceed, plus an additional six months of commissioning and ramp-up to 100% of
production capacity for a total of 45 months and assumes no financing constraints. The NioCorp board must approve a construction program and budget before construction
of the Elk Creek Project can begin. This approval, along with the receipt of all required governmental permits and approvals and the completion of project financings, will
determine whether and when construction of the Elk Creek Project can begin.

Proposed Tailings Storage

The  tailings  produced  by  the  process  plant  will  consist  of  filtered  water  leach  residue,  calcined  excess  oxide,  and  slag.  Four  engineered  and  lined  tailings  storage
facilities (“TSFs”) will be constructed sequentially to contain the tailings over the life of the Elk Creek Project and would contain approximately 14.5 million tonnes of
tailings.  The  tailings  facilities  have  been  designed  to  incorporate  two  independent  areas:  a  composite-lined  tailings  solids  storage  area;  and  an  area  with  double  lined
containment, including a leak collection and recovery system for management of stormwater runoff and drainage from the tailings solids. The TSFs will store predominantly
dry (i.e., not in a slurry consistency) tailings from the plant with embankment construction based on a “downstream” construction method. Facility closure is considered in
the design.

Proposed Salt Management

The  crystalline  salt  produced  as  a  waste  product  of  heating  and  evaporating  brine  from  the  reverse  osmosis  (“RO”)  water  treatment  plant  will  be  transported  by
conveyor to the temporary salt staging area and then be transported by truck to the dedicated salt management cells (“SMC”). Two SMCs will be constructed sequentially to
contain the salt over the life of the project and would contain approximately 1.63 million cubic meters of salt. The SMCs design will incorporate a composite-lined storage
area with double-lined containment including a leak collection and recovery system for management of stormwater runoff and drainage.

Proposed Water Management

For the first several years of construction, the advancement of the shaft and underground workings will require limited dewatering, anticipated to be through lower-level
sumping and pumping for surface collection and disposal. Initially, water will be stored in the lined SMC #1 during construction or will be trucked off-site for treatment at a
local publicly owned treatment works. Excess water in the SMCs will be spray evaporated within the footprint of the SMC, to avoid the reintroduction of soluble salts into
the water treatment system. Temporary on-site storage or off-site shipment and disposal of the crystallizer solid waste may be necessary until construction of SMC #1 is
completed.

36

 
 
 
 
 
 
 
 
 
 
 
 
 
Once  full  operations  commence,  we  anticipate  a  shortfall  of  approximately  3,700  gallons  per  minute  of  operational  and  processing  water,  as  the  underground  mine

dewatering is only expected to produce 1,000 gallons per minute. To make up this shortfall, we would purchase fresh water from a local utility and from local landowners.

Once tailings begin being deposited in the TSF, internal contact water (from residual moisture in the tailings and precipitation falling within the impoundment footprint)
will need to be actively managed. This water will be collected and treated using lime softening to precipitate hydroxide and carbonate solid forms for many of the inorganic
constituents. The treated water will be filtered to remove the solids (which will be returned to the TSF for disposal), and the clean water will be pumped to the process plant
RO  system  for  further  treatment.  The  clean  water  from  the  process  plant  RO  unit  will  be  used  in  the  process  plant,  and  the  reject  concentrate  will  be  crystallized  and
deposited into the SMCs.

Proposed Source of Power

The  local  power  utility  (Omaha  Public  Power  District)  will  provide  power  from  nearby  transmission  lines  to  the  site. This  will  require  that  an  approximate  18-mile
transmission line be installed by the utility to provide the site sub-station with the required site power demand. The local power utility will also design and install the main
substation that will be owned and maintained by the utility. This infrastructure will be paid back through rate charges on the electrical usage.

Proposed Source of Natural Gas

Natural gas, to be used throughout the Elk Creek Project during the construction and operation phases of the project, will be brought to the site via pipeline from the
local  utility  company.  NioCorp  has  a  natural  gas  transportation  contract  with  Tallgrass  Energy,  which  operates  the  Rockies  Express  (“REX”)  pipeline.  Tallgrass  will
construct a 45 kilometer (28 mile) gas pipeline lateral from the main REX pipeline system in Kansas to the project site. The lateral will be sized to provide a minimum of
27.5 dekatherms of gas per day. Natural gas will be distributed to all on-site facilities utilizing buried high-density polyethylene natural gas distribution pipe. Natural gas
piping above ground and located inside of facilities will consist predominately of carbon steel pipe. Maximum on-site pipeline distribution pressure will be 100 pounds per
square inch gauge. Natural gas will be used for facility heating, water heating, and for gas-fired process equipment.

Markets

Market studies for niobium, TiO2, and Sc2O3 are an important part of the proposed Elk Creek operation. These commodities, especially niobium and Sc2O3, are thinly
traded  without  an  established  publicly  available  price  discovery  mechanism.  Hence,  detailed  third-party  market  studies  provide  the  basis  for  assumptions  used  in  the
economic analysis.

The economic analysis in the 2022 Elk Creek Feasibility Study used the 2019 U.S. dollar base price of $47/kg Nb as the forward-looking price for steel grade (65%)
ferroniobium based on published independent third-party reports. The base price is adjusted to a realized price to account for the discount provisions contained in the two
ferroniobium offtake agreements that the Company has concluded.

NioCorp  engaged  OnG  Commodities  LLC  (“OnG”)  to  produce  a  market  assessment  in  April  2017.  The  study  examines  current  scandium  production  trends
(approximately 20 tons/year) from existing and emerging producers plus an outlook for supply to 2028. The outlook then reviewed the current and emerging applications for
scandium, including fuel cells, aerospace, industrial and other uses, plus an outlook for demand to 2028. Based on these inputs, OnG provided pricing forecasts and global
demand  volumes  by  year  to  2028  based  estimated  production  costs  and  supply-demand  balances.  The  pricing  sheet  for  the  OnG  Commodities  report  was  updated  for
NioCorp in 2019.

No formal market study was done for TiO2 as it only represents 2% of overall revenue in the economic analysis. All market information for titanium and TiO2 is derived

from USGS Commodity Market Summaries (Bedinger, 2019).

Taxation Rates Included in the 2022 Elk Creek Feasibility Study

Taxes that may be levied on the Elk Creek Project include corporate income tax rates of 21% for federal and 5.84% for Nebraska. The Elk Creek Project is eligible for
federal  depletion  allowances  and  credits,  as  well  as  various  state  incentives.  The  calculated  effective  income  tax  rate  for  the  Elk  Creek  Project  is  16.42%  for  the  2022
Feasibility Study.

Design Considerations for Environmental Performance

The current mine design incorporates these following strategies and technologies designed to minimize environmental impacts of operation:

● Zero Process Liquid Discharge: The Elk Creek facility will now operate as a “Zero Process Liquid Discharge” facility, with no releases of process liquids. Instead,
both  naturally  occurring,  brackish  (slightly  salty)  water  produced  during  mining  operations,  and  water  used  in  ore  processing,  will  be  treated  on  site  for  use  in
operations. A solid salt will be produced from water treatment operations which will be stored on site.

● Additional  Protection  of  Groundwater  Resources  Through  Artificial  Ground  Freezing:  The  Elk  Creek  Project’s  new  mine  design  will  utilize  artificial  ground
freezing as part of the process of sinking the production and ventilation shafts. Artificial ground freezing creates a temporary frozen barrier that helps to protect
groundwater resources in the area while shaft-sinking operations are underway.

● Avoidance of Permanent Impacts to Federally Jurisdictional Waters: We designed the layout of the Elk Creek Project to minimize or avoid permanent impacts to
any federally jurisdictional waters and/or wetlands on the property. This reduced the expected environmental impacts and allowed the Elk Creek Project to secure a
Clean Water Act Section 404 permit from the USACE under the Nationwide Permit Program, a much more efficient and less expensive process than an individual
Section 404 permit. No other NEPA-level federal permits are now expected to be required for the Elk Creek Project.

● Recycling of Reagents Used in Mineral Processing: Metallurgical and process advances made in 2016 and 2017 are expected to help reduce the volume of material
planned for disposal in the Elk Creek Project’s tailings storage areas. As more of this material is recycled, the environmental footprint of the Elk Creek Project is
reduced.

● Utilizing  Tailings  as  Underground  Mine  Backfill:  We  plan  to  fill  underground  voids  concurrently  with  mining  operations  using  a  paste  backfill  material  that

contains mine waste material that typically would be stored in above-ground tailings storage areas.

The Company has not identified any significant encumbrances to the property it owns or holds under OTP agreements. The Company has not had any permit violations

or fines since the filing of our Annual Report on Form 10-K for the fiscal year ended June 30, 2022.

Permitting requirements for the project have been identified. The Company holds an Air Construction Permit from the State of Nebraska and a Special Use Permit from
Johnson County, both of which are necessary to allow the start of project construction. In addition, the Elk Creek Project will be required to obtain a series of permits for
operations from federal, state, and local agencies. The majority of these permits are ministerial in nature and present minimal risk to the Company, and typically involve the
completion  of  an  application  and  the  payment  of  a  nominal  fee. Three  permits  from  the  state  of  Nebraska  are  discretionary  in  nature,  where  an  application  and  fee  are
provided to the state and the state must make a decision as to whether or not the permit will be granted. While the risk involved in such permits is low, such discretionary
permits require more processing time by the state and do require the state agency to make a decision in favor of issuance of the permit. These three permits include the
following:

● Solid Waste Permit;
● Air Operating Permit; and
● Radioactive Materials License.

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The cost and schedule for obtaining both the discretionary and ministerial permits is included in the overall execution plan for the Elk Creek Project. Additional details

c. The mineral resources are reported at a Diluted Net Smelter Return (NSR) Cut-off of US$180/tonne.
d. The diluted NSR is defined as:

●  Diluted NSR (US$)=

Revenue per block Nb2O5 (diluted) + Revenue per block TiO2 (diluted) + Revenue per block Sc (diluted)
Diluted tonnes per block

● The diluted revenue from Nb2O5, TiO2, and Sc per block used the following factors:

● Nb2O5 Revenue: a 94% grade recovery, a 0.696 factor to convert Nb2O5 to Nb, 82.36% assumption for plant recovery, and a US$39.60 selling price per kg

of ferroniobium as of June 30, 2022.

● TiO2 Revenue: a 94% grade recovery, a 40.31% assumption for plant recovery, and an US$0.88 kg selling price per kg of titanium oxide as of June 30,

2022.

● Sc Revenue: a 94% grade recovery, a 1.534 factor to convert Sc to Sc2O3, 93.14% assumption for plant recovery, and a US$3,675 selling price per kg of

scandium oxide as of June 30, 2022.

● The diluted tonnes are a 6% increase in the total tonnes of the block.

e. Price assumptions for FeNb, Sc2O3, and TiO2 as shown in note d, above, are based upon independent market analyses for each product.
f. Numbers may not sum due to rounding. The rounding is not considered to be material.
g. Rare Earth Oxides (REO) were evaluated as a potential by-product to the mining of niobium, titanium, and scandium; thus, the estimated values of the REOs are

reported using the previously determined diluted NSR as derived from the Nb2O5, TiO2, and Sc mineral resources and are assigned a price of $0

h. The stated Light Rare Earth Oxides (LREO) grade (%) is the summation of La2O3 (%), Ce2O3 (%), Pr2O3 (%), and Nd2O3 (%) estimates.

● The Qualified Person for the mineral reserve estimate is Optimize Group Inc. The estimate has an effective date of June 30, 2023.
● The mineral reserve is based on the mine design, mine plan, and cash-flow model utilizing an average cut-off grade of 0.679% Nb2O5 with an NSR of US$180/mt.
● The  estimate  of  mineral  reserves  may  be  materially  affected  by  metal  prices,  environmental,  permitting,  legal,  title,  taxation,  socio-political,  marketing,

infrastructure development, or other relevant issues.

● The economic assumptions used to define mineral reserve cut-off grade are as follows:

○ Annual life of mine (LoM) production rate of ~7,450 tonnes of FeNb/annum during the years of full production.
○ Initial elevated five-year production rate ~ 7,500 tonnes of FeNb/annum when full production is reached.
○ Mining  dilution  of  ~6%  was  applied  to  all  stopes  and  development,  based  on  3%  for  the  primary  stopes,  9%  for  the  secondary  stopes,  and  5%  for  ore

development.

○ Mining recoveries of 95% were applied in longhole stopes and 62.5% in sill pillar stopes.

● Price  assumptions  are  as  follows:  FeNb  US$39.60/kg  Nb,  Sc2O3  US$3,675/kg,  and  TiO2  US$0.88/kg.  Price  assumptions  are  based  upon  independent  market

analyses for each product as of June 30, 2022.

● Price  and  cost  assumptions  are  based  on  the  pricing  of  products  at  the  “mine-gate,”  with  no  additional  down-stream  costs  required.  The  assumed  products  are

ferroniobium (metallic alloy shots consisting of 65%Nb and 35% Fe), a titanium dioxide product in powder form, and scandium trioxide in powder form.

● The mineral reserve has an average LoM NSR of US$563.06/tonne.
● Optimize  Group  has  provided  detailed  estimates  of  the  expected  costs  based  on  the  knowledge  of  the  style  of  mining  (underground)  and  potential  processing

methods (by 3rd party Qualified Persons).

● Mineral reserve effective date is June 30, 2023. The financial model was run after the estimate of the NSR above, which reflects a total cost per tonne of US$196.72

versus US$189.91. This is not considered a material change.

● Price variances for commodities are based on independent market studies versus earlier projected pricing. The independent market studies do not have a negative

effect on the reserve.

Comparison of Mineral Resources and Mineral Reserves

There were no changes in the Elk Creek Project mineral resource or reserve estimates as of June 30, 2023, as compared to the Elk Creek Project mineral resource and

reserve estimates as of June 30, 2022.

Environmental and Social

A number of key permits and environmental management requirements have been identified for the Elk Creek Project, some of which need to be implemented as soon

as practicable in order to maintain the proposed Elk Creek Project schedule.

● While  not  necessarily  complex,  the  timing  generally  required  to  complete  permitting  through  any  federal  regulatory  agency  requires  that  NioCorp  engage  key
agencies (in this case the USACE and possibly the EPA) early on in Elk Creek Project development and consider the siting and orientation of facilities carefully to
minimize the risk of a protracted National Environmental Policy Act analysis of the Elk Creek Project. At the present time, the company believes that we have
completed  the  major  federal  permitting  actions  needed  for  project  construction,  although  changes  to  the  design  or  location  of  project  facilities  may  require  that
additional federal permits be obtained.

● Construction at the facility requires the Air Permit from the State of Nebraska, which was issued to the Company on June 2, 2020. The Air Permit describes all the
prospective air emissions from the facility and required the completion of an air quality model that demonstrates compliance with the NAAQS. On April 15, 2022,
the Company announced that the Nebraska Department of Environment and Energy advised the Company that periodic extensions to the Elk Creek Project’s Air
Permit  are  no  longer  required  because  the  Company  has  met  the  regulatory  definition  of  “construction,  reconstruction,  or  modification  of  the  source”  since  the
permit was issued.

● A radioactive materials license will be needed from the Nebraska Department of Health and Human Services (“NDHHS”), Office of Radiological Health. Because
of their limited experience with hard rock mining in the State of Nebraska, much less mining that includes Naturally Occurring Radioactive Material, the NDHHS
may require additional information and more time to approve the Elk Creek Project under a Broad Scope License. The Company has been working with NDHHS
on this aspect of project permitting since 2014.

● Documentation  of  existing  baseline  environmental  conditions  at  the  Elk  Creek  Project  site  was  initiated  in  2014  and  will  continue  as  needed  throughout  the

permitting process.

● Surface water monitoring will continue throughout the permitting process and extend into construction and operations as part of the Environmental Management

System and likely State of Nebraska permit requirements.

41

 
 
 
 
 
 
 
 
 
 
 
 
 
● A wetland delineation and potential jurisdictional waters assessment was conducted in late 2014 to identify wetland and drainage features within the proposed Elk

Creek Project boundary which resulted in a formal JD being issued by the USACE on September 6, 2016.

● The major land-use authorization for the project was received from Johnson County, Nebraska, on December 24, 2019, in the form of a Special Use Permit for the
project. This land-use permit is a necessary precursor to any project-related construction activities. County zoning permits will be required for individual buildings
constructed at the site, and the County requirement is that such applications must be submitted five days before construction commences.

● Closure costs for the Elk Creek Project have been estimated at just over $44 million, including approximately $13.5 million for reclamation and closure of the TSFs

and $16.6 million for plant and building removal and reclamation.

● Community  engagement  has  occurred  in  parallel  with  Nebraska  field  operations  and  has  included  public  meetings,  presentations  to  public  agencies,

communications with local and state politicians, meetings with environmental groups, and one-on-one meetings with area landowners.

Other Elk Creek Project Activities

On September 6, 2022, the Company announced that the Demonstration Plant had commenced processing a three-tonne sample of representative ore from the Elk Creek
Project. The Demonstration Plant project is intended to demonstrate that the Company can extract and separate rare earth elements from ore that NioCorp expects to mine
from the Elk Creek Project site, subject to receipt of necessary project financing, and that its simplified process for potentially producing niobium, scandium, and titanium is
technically and economically feasible.

On October 25, 2022, the Company announced that the Demonstration Plant had completed demonstrating its planned process for removing calcium and magnesium
from ore obtained from the Elk Creek Project. This positive result is a key milestone in NioCorp’s proposed optimization of its process flow sheet for the Elk Creek Project,
which was designed by L3 and NioCorp. Removing carbonate minerals in this fashion is expected to reduce the size of the follow-on planned production steps and make
them more efficient. Characterization of the calcium and magnesium carbonate from the completed Demonstration Plant production runs has demonstrated very low levels
of impurities, and an overall 99% purity of the mixed calcium-magnesium carbonate.

On January 4, 2023, the Company announced that the Demonstration Plant has succeeded in obtaining a rare earth dissolution rate of 86-95% from ore from the Elk
Creek Project site through hydrochloric acid leaching and has achieved a loading rate of rare earths as high as 99% in the follow-on solvent extraction recovery step. These
relatively high rates, which were expected, point to potentially strong rates of overall recovery of separated rare earth oxides, subject to additional demonstration testing.

On February 6, 2023, the Company announced that overall recoveries for praseodymium oxide, neodymium oxide, terbium oxide, and dysprosium oxide are likely to be
greater than 92% and meet commercial purity specifications for magnetic rare earth oxides. These results are in line with bench- and pilot-scale testing of L3’s rare earth
recovery system, as well as hydrometallurgical performance models that have been run on the rare earth recovery process upon which the Demonstration Plant is based.

On February 20, 2023, the Company announced that it had executed a contract with Zachry Group (“Zachry”) to develop a cost for the surface facilities associated with
the Elk Creek Project. The contract represents the first phase of EPC contracting for the Elk Creek Project. NioCorp had previously selected Zachry as its EPC firm for the
Elk Creek Project’s surface facilities.

On April 4, 2023, the Company announced a process breakthrough in niobium and titanium recovery achieved at the Demonstration Plant. The breakthrough points to a
potentially more efficient way to process niobium and titanium into higher-purity products, which may in turn open up new markets for the Elk Creek Project’s planned
products.

On May 25, 2023, the Company announced that it has successfully demonstrated the ability to recover greater amounts of the critical mineral niobium from each tonne

of ore the Company expects to mine at the Elk Creek Project,

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
once  sufficient  financing  is  obtained  and  the  project  is  constructed.  Final  results  from  the  demonstration  show  that  NioCorp’s  new  and  improved  recovery  process  can
achieve a 90.7% rate of niobium recovery through the hydrometallurgical process. Overall recovery through the pyrometallurgical production of the commercial product
ferroniobium  is  expected  to  be  86.7%.  NioCorp’s  previous  approach  to  niobium  production  was  able  to  achieve  recovery  rates  through  the  hydrometallurgical  and
pyrometallurgical processes of 86.8% and 82.4%, respectively.

On May 26, 2023, the Company announced that it has successfully demonstrated an ability to potentially double the recovery of titanium from each tonne of ore the
Company expects to mine at the Elk Creek Project. The new process is expected to produce a purer form of titanium that may command a higher price than is assumed in the
2022 Elk Creek Feasibility Study. The Demonstration Plant has shown that the Company’s new and improved recovery process can likely achieve an 83.7% rate of overall
titanium recovery to final product. This compares to a 40.3% titanium recovery rate in NioCorp’s previous process approach. This new result points to a potentially large
increase in the amount of titanium that NioCorp can potentially produce at currently planned rates of mining.

Based  on  results  of  the  Company’s  Demonstration  Plant,  a  higher  value  titanium  tetrachloride  product  can  be  produced  with  a  substantially  higher  metallurgical
recovery than TiO2. The Company is in the process of completing feasibility level cost estimates to replace the previous TiO2 production equipment with new equipment
that would produce titanium tetrachloride.

On June 1, 2023, the Company announced the successful completion of a geotechnical drilling campaign at the Elk Creek Project, which was done in advance of the
proposed site preparation, grading, heavy construction, and eventual foundation pours for the Elk Creek Project that are expected to commence once sufficient financing is
obtained. The campaign involved drilling 16 boreholes and 20 test pits across the one square mile Elk Creek Project site, analyzing soil samples, and generating data for
engineering  design  firms  that  are  continuing  to  finalize  plans  for  the  potential  construction  of  the  facility.  The  campaign  also  involved  the  installation  of  6  shallow
groundwater piezometers to monitor water levels in the soil layer, which will also aid in construction planning.

Proposed Activities

At present, the Company is maintaining the Elk Creek property in anticipation of obtaining project financing that will facilitate the construction, commissioning, and
operation of the Elk Creek Project. The property is characterized as a development stage property and is expected to move to a production stage property should financing be
obtained.

As funds become available through the Company’s fundraising efforts, we expect to undertake the following activities:

● Continuation of the Company’s efforts to secure federal, state and local operating permits;

● Continued evaluation of the potential to produce rare earth products and sell such products under offtake agreements;

● Negotiation and completion of offtake agreements for the remaining uncommitted production of Nb, Sc, and Ti from the project, including the potential sale of Ti as

titanium tetrachloride;

● Negotiation and completion of engineering, procurement, and construction agreements;

● Completion of the final detailed engineering for the underground portion of the Elk Creek Project;

● Initiation and completion of the final detailed engineering for surface project facilities;

● Construction of natural gas and electrical infrastructure under existing agreements to serve the Elk Creek Project site;

● Completion of water supply agreements and related infrastructure to deliver fresh water to the project site;

● Initiation of revised mine groundwater investigation and control activities;

● Initiation of long-lead equipment procurement activities; and

● As a follow-on to the Company’s Demonstration Plant operations, complete characterization and testing of waste materials to support tailings impoundment and

paste backfill plant designs.

Non-GAAP Financial Performance Measures

Non-GAAP financial performance measures are intended to provide additional information only and do not have any standard meaning prescribed by U.S. GAAP. These

measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with U.S. GAAP.

The  S-K  1300  Elk  Creek Technical  Report  Summary  uses  non-GAAP  financial  performance  measures,  such  as  EBITDA, Averaged Annual  EBITDA,  and Averaged
EBITDA Margin, for purposes of projecting the economic results of the Elk Creek Project. We are unable to provide a reconciliation of these forward-looking non-GAAP
measures  to  the  most  comparable  U.S.  GAAP  financial  performance  measures  because  certain  information  needed  to  reconcile  those  non-GAAP  measures  to  the  most
comparable U.S. GAAP financial performance measures is dependent on future events, some of which are outside the control of the Company, such as FeNb, Sc2O3, and
TiO2 prices, interest rates, and exchange rates. Moreover, estimating such U.S. GAAP measures with the required precision necessary to provide a meaningful reconciliation
is extremely difficult and could not be accomplished without unreasonable effort.

ITEM 3.

LEGAL PROCEEDINGS

As of October 6, 2023, we are not a party to any legal proceedings that could have a material adverse effect on the Company’s business, financial condition, or operating

results. Further, to the Company’s knowledge, no such proceedings have been threatened against the Company.

ITEM 4.

MINE SAFETY DISCLOSURES

Pursuant  to  Section  1503(a)  of  the  United  States  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection Act  of  2010  (the  “Dodd-Frank Act”),  issuers  that  are
operators, or that have a subsidiary that is an operator, of a coal or other mine in the U.S. are required to disclose specified information about mine health and safety in their
periodic reports. These reporting requirements are based on the safety and health requirements applicable to mines under the Federal Mine Safety and Health Act of 1977
(the “Mine Act”) which is administered by the U.S. Department of Labor’s Mine Safety and Health Administration (“MSHA”). During the fiscal year ended June 30, 2023,
the Company and its subsidiaries and their properties or operations were not subject to regulation by MSHA under the Mine Act and thus no disclosure is required under
Section 1503(a) of the Dodd-Frank Act.

Exchange Controls

There are no governmental laws, decrees, or regulations in Canada that restrict the export or import of capital, including foreign exchange controls, or that affect the
remittance of dividends, interest or other payments to non-resident holders of the securities of NioCorp, other than Canadian withholding tax. See “Certain Canadian Federal
Income Tax Considerations for U.S. Residents” below.

Certain Canadian Federal Income Tax Considerations for U.S. Residents

The following generally summarizes certain Canadian federal income tax consequences generally applicable under the Income Tax Act (Canada) and the regulations
enacted  thereunder  (collectively,  the  “Canadian  Tax  Act”)  and  the  Canada-United  States  Tax  Convention  (1980)  (the  “Convention”)  to  the  holding  and  disposition  of
Common Shares.

Comment is restricted to holders of Common Shares each of whom, at all material times for the purposes of the Canadian Tax Act and the Convention, (i) is resident
solely in the U.S. for tax purposes, (ii) is a “qualifying person” under and entitled to the benefits of the Convention, (iii) holds all Common Shares as capital property, (iv)
holds no Common Shares that are “taxable Canadian property” (as defined in the Canadian Tax Act) of the holder, (v) deals at arm’s-length with and is not affiliated with
NioCorp, (vi) does not and is not deemed to use or hold any Common Shares in a business carried on in Canada, (vii) is not an insurer that carries on business in Canada and
elsewhere, and (viii) is not an “authorized foreign bank” (as defined in the Canadian Tax Act)(each such holder, a “U.S. Resident Holder”).

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Certain U.S.-resident entities that are fiscally transparent for U.S. federal income tax purposes (including limited liability companies) may not in all circumstances be
entitled to the benefits of the Convention. Members of or holders of an interest in such an entity that holds Common Shares should consult their own tax advisers regarding
the extent, if any, to which the benefits of the Convention will apply to the entity in respect of its Common Shares.

Generally, a U.S. Resident Holder’s Common Shares will be considered to be capital property of such holder provided that the U.S. Resident Holder is not a trader or
dealer in securities, did not acquire, hold, or dispose of the Common Shares in one or more transactions considered to be an adventure or concern in the nature of trade (i.e.
speculation), and does not hold the Common Shares in the course of carrying on a business.

This summary is based on the current provisions of the Canadian Tax Act and the Convention in effect as of the date prior to the date hereof, all specific proposals to
amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, and the current published
administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”). It is assumed that all such amendments will be enacted as currently proposed,
and that there will be no other material change to any applicable law or administrative policy or assessing practice, whether by way of judicial, legislative or governmental
decision or action, although no assurance can be given in these respects. This summary is not exhaustive of all possible Canadian federal income tax considerations. Except
as otherwise expressly provided, this summary does not take into account any provincial, territorial, or foreign tax considerations, which may differ materially from those set
out herein.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be and should not
be  construed  as  legal  or  tax  advice  to  any  particular  U.S.  Resident  Holder.  U.S.  Resident  Holders  are  urged  to  consult  their  own  tax  advisers  for  advice  with
respect to their particular circumstances. The discussion below is qualified accordingly.

Generally, a U.S. Resident Holder’s Common Shares will not constitute “taxable Canadian property” of such holder at a particular time at which the Common Shares

are listed on a “designated stock exchange” (which currently includes the TSX and Nasdaq) unless both of the following conditions are concurrently met:

1. at any time during the 60-month period that ends at the particular time, 25% or more of the issued shares of any class of the capital stock of NioCorp were owned by

or belonged to one or any combination of:

the U.S. Resident Holder,

a.
b. persons with whom the U.S. Resident Holder did not deal at arm’s length, and
c. partnerships  in  which  the  U.S.  Resident  Holder  or  a  person  referred  to  in  clause  (b)  holds  a  membership  interest  directly  or  indirectly  through  one  or  more

partnerships, and

2. at  any  time  during  the  60-month  period  that  ends  at  the  particular  time,  more  than  50%  of  the  fair  market  value  of  the  Common  Shares  was  derived  directly  or
indirectly from, one or any combination of, real or immovable property situated in Canada, “Canadian resource properties” (as defined in the Canadian Tax Act),
“timber resource properties” (as defined in the Canadian Tax Act), or options in respect of, or interests in any of the foregoing, whether or not the property exists.

Common Shares may also be deemed to be “taxable Canadian property” in certain circumstances set out in the Canadian Tax Act.

A U.S. Resident Holder who disposes or is deemed to dispose of one or more Common Shares generally should not thereby incur any liability for Canadian federal

income tax in respect of any capital gain arising as a consequence of the disposition.

A  U.S.  Resident  Holder  to  whom  NioCorp  pays  or  credits  or  is  deemed  to  pay  or  credit  a  dividend  on  such  holder’s  Common  Shares  will  be  subject  to  Canadian
withholding tax, and NioCorp will be required to withhold the tax from the dividend and remit it to the CRA for the holder’s account. The rate of withholding tax under the
Canadian Tax Act is 25% of the gross amount of the dividend, but should generally be reduced under the Convention to 15% (or, if the U.S. Resident Holder is a company
which is the beneficial owner of at least 10% of the voting stock of NioCorp, 5%) of the gross amount of the dividend. For this purpose, a company that is a resident of the
United States for purposes of the Canadian Tax Act and the Convention and is entitled to the benefits of the Convention shall be

46

 
 
 
 
 
 
 
 
 
 
 
 
 
considered to own the voting stock of NioCorp owned by an entity that is considered fiscally transparent under the laws of the United States and that is not a resident of
Canada, in proportion to such company’s ownership interest in that entity.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis (“MD&A”) provides information that management believes is relevant to an assessment and understanding of
the  consolidated  financial  condition  and  results  of  operations  of  NioCorp  and  subsidiaries.  This  item  should  be  read  in  conjunction  with  our  consolidated  financial
statements and the notes thereto included in this Annual Report on Form 10-K.

See Item 1, “Business – Recent Corporate Events,” for a description of the Transactions.

Summary of Consolidated Financial and Operating Performance

The Company had no revenues from mining operations during the fiscal years presented below. Operating expenses incurred related primarily to performing exploration

and feasibility study related activities, as well as the activities necessary to support corporate and shareholder duties.

The net loss attributable to the Company increased to $40.1 million for fiscal year 2023 from $10.9 million for fiscal year 2022. This increased net loss in fiscal year
2023 as compared to fiscal year 2022 is primarily due to the recognition of Earnout Shares and warrant liabilities associated with the GXII Transaction as well as an increase
in legal and other professional fees.

The net loss attributable to the Company increased to $10.9 million for fiscal year 2022 from $4.8 million for fiscal year 2021. This increased net loss in fiscal year
2022 as compared to fiscal year 2021 is primarily due to increased exploration expenditures associated with process development costs and rare earth review costs, as well
increased non-cash costs of our fiscal year 2022 Option grants, which were fully vested and expensed on the grant dates, and increased loss on partial debt extinguishment
from debt conversions reported as interest expense.

Results of Operations

The  Company  had  no  revenues  from  mining  operations  during  the  fiscal  years  presented  below.  Operating  expenses  incurred  related  primarily  to  costs  incurred  in
connection with the Transactions, as well as performing exploration and feasibility study related activities, and the activities necessary to support corporate and shareholder
duties, as detailed in the following table.

Other  operating  expenses  include  costs  incurred  in  connection  with  the  Transactions,  including  direct  transaction  expenses,  and  the  fair  value  of  warrant  and
Earnout  Shares  liabilities  assumed,  as  well  as  costs  related  to  investor  relations,  general  office  expenditures,  equity  offering  and  proxy  expenditures,  board-related
expenditures, and other miscellaneous costs. These costs increased in fiscal year 2023 as compared to fiscal year 2022 primarily due to the costs incurred in connection
with the Transactions, which closed on March 17, 2023. A summary of these costs is presented below:

In addition, other operating expenses increased due to increased directors and officers insurance premiums associated with our US stock exchange listing, as well as

increased financial and investor relation services performed during 2023.

Exploration expenditures increased in fiscal year 2023 as compared to fiscal year 2022, reflecting work performed in fiscal year 2023 to complete the development
of the Demonstration Plant and the subsequent operation of the Demonstration Plant to verify process improvement efforts and advance the technical and economic
analyses  on  the  potential  addition  of  magnetic  rare  earth  oxides  to  NioCorp’s  planned  product  suite.  In  addition,  2023  costs  increased  due  to  costs  related  to  the
completion and filing of the Technical Report Summary

based on the Company’s 2022 Feasibility Study for the Elk Creek Project, which was filed with the SEC on September 6, 2022.

Professional fees increased in fiscal year 2023 as compared to fiscal year 2022, primarily due to additional accounting and legal services related to our March 31,

2023 Form 10-Q SEC filings, as well as legal costs associated with corporate funding initiatives.

Employee  related  costs  for  fiscal  year  2023  increased  as  compared  to  fiscal  year  2022  primarily  due  to  the  impact  of  discretionary  bonus  payouts  totaling  $0.2

million, partially offset by the impact of lower employee headcount at the end of fiscal year 2023 as compared to fiscal year 2022.

Other significant items impacting the change in the Company’s net loss are noted below:

Change in fair value of Earnout Shares liability represents the change in fair value related to the Earnout Shares between the Closing Date and the end of fiscal year

2023, based on the results of Monte Carlo financial modeling.

Change  in  fair  value  of  warrant  liability  represents  the  change  in  fair  value  related  to  the  additional  Warrants  (the  “Contingent  Consent  Warrants”)  that  the
Company agreed to issue to Lind Global Asset Management III, LLC (“Lind”) upon certain conditions in connection with the Waiver and Consent Agreement, dated
September 25, 2022, between the Company and Lind (the “Lind Consent”), as discussed in Note 9 to the consolidated financial statements included in Part II, Item 8
hereof,  as  well  as  the  change  in  the  fair  value  of  the  Private Warrants  based  primarily  on  the  impacts  of  a  lower  closing  Common  Share  price,  which  increases  the
probability of these Contingent Consent Warrants being issued under the Lind Consent terms.

Loss  on  debt  extinguishment  represents  the  loss  incurred  under Accounting  Standards  Codification  (“ASC”) Topic  470,  Debt,  related  to  the  convertible  security
issued to Lind (the “Lind III Convertible Security”) with a face value of $11.7 million (representing $10.0 million in funding plus an implied 8.5% interest rate per
annum for the term of the Lind III Convertible Security) pursuant to the Convertible Security Funding Agreement, dated February 16, 2021, as amended by Amendment
#1 to the Convertible Security Funding Agreement, dated December 2, 2021, between the Company and Lind (as amended, the “Lind III Agreement”), as discussed in
Note 9 to the consolidated financial statements included in Part II, Item 8 hereof.

Interest  expense  decreased  in  fiscal  year  2023  as  compared  to  fiscal  year  2022  due  to  the  impacts  of  conversions  on  the  outstanding  balance  of  the  Lind  III
Convertible Security during fiscal year 2022, as well as the impact of debt extinguishment accounting as discussed in Note 9 to the consolidated financial statements
included in Part II, Item 8 hereof, partially offset by Convertible Debenture interest expense incurred in fiscal year 2023.

Loss attributable to noncontrolling interest represents the portion of net loss in ECRC attributable to the Vested Shares, which are not owned by the Company.

Fiscal Year 2022 as Compared to Fiscal Year 2021

Significant items affecting operating expenses are noted below:

Employee related costs for fiscal year 2022 increased as compared to fiscal year 2021 primarily due to increased share-based compensation costs which primarily

reflected the impact of increased Common Share values on the fair value calculations in the Black-Scholes model, as well as the number of Options granted.

Professional fees increased in fiscal year 2022 as compared to fiscal year 2021, primarily due to additional legal services related to SEC filings, including our shelf

registration statement on Form S-3 filed in November 2021.

49

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Exploration expenditures increased in fiscal year 2022 as compared to fiscal year 2021 reflecting work performed in fiscal year 2022 to advance the development of
a  demonstration-scale  test  plant  to  verify  process  improvement  efforts  as  well  as  to  potentially  incorporate  REEs  into  our  planned  production.  Fiscal  year  2021
expenditures primarily related to the ongoing personnel costs, as well as ongoing engineering and metallurgical projects and project advancement activities.

Other  operating  expenses  include  investor  relations,  general  office  expenditures,  equity  offering  and  proxy  expenditures,  board-related  expenditures,  and  other
miscellaneous costs. These costs increased in fiscal year 2022 as compared to fiscal year 2021 primarily due to increased financial advisory fees and investor relations
fees associated with our ongoing financing efforts. In addition, share-based compensation for directors and other advisors increased in fiscal year 2022 as compared to
fiscal year 2021 due to increased share-based compensation costs, which primarily reflected the impact of increased Common Share values in the Black Scholes model.
Options issued in both periods were fully vested upon issuance and expensed on the grant date.

Other significant items impacting the change in the Company’s net loss are noted below:

Other income for fiscal year 2021 represents the one-time forgiveness of the Company’s U.S. Small Business Administration Loan, which occurred on November

18, 2020.

Loss on extinguishment for fiscal year 2021 represents the one-time loss incurred in connection with the December 18, 2020, conversion of a convertible note in the
principal  amount  of  approximately  $1.9  million  issued  by  the  Company  to  Nordmin  pursuant  to  a  convertible  note  and  warrant  subscription  agreement,  dated  as  of
December 18, 2020, between NioCorp and Nordmin (the “Nordmin Note”).

Foreign exchange (gain) loss is primarily due to changes in the U.S. dollar against the Canadian dollar rate as applied to U.S. dollar-denominated debt instruments,
which are carried on the Canadian parent company books, and the fiscal year 2022 loss reflected the impacts of a strengthened U.S. dollar to Canadian dollar, whereas
the fiscal year 2021 gain primarily reflects the impact of a weakened U.S. dollar.

Interest expense increased in fiscal year 2022 as compared to fiscal year 2021 primarily due to the accretion of the Nordmin Note, which was issued in December

2020, as well as accretion of the Lind Convertible Security, which was issued in February 2021.

Liquidity and Capital Resources

We have no revenue generating operations from which we can internally generate funds. To date, our ongoing operations have been financed by the sale of our equity
securities by way of private placements, convertible securities issuances, the exercise of incentive Options and Warrants, and related party loans. With respect to currently
outstanding Options and Warrants, we believe that exercise of these instruments, and cash proceeds from such exercises, will not occur unless and until the market price for
our Common Shares equals or exceeds the related exercise price of each instrument.

In connection with the Closing of the Transactions, the Company received net cash proceeds of $8.3 million, as follows:

The  Transactions  delivered  to  NioCorp  several  important  benefits,  including  a  ready  pathway  to  an  up-listing  to  the  Nasdaq,  which  is  expected  to  allow  additional
institutional firms to invest in the Company for the first time. Further, we believe it has given NioCorp and the Elk Creek Project a much higher profile among institutional
investors evaluating projects in the critical materials space.

The Yorkville Convertible Debt Financing has provided, and the Yorkville Equity Facility Financing is expected to provide, near-term and longer-term access to capital.
The ability of the Company to draw down on the Yorkville Equity Facility Financing Agreement, at its discretion, is subject to certain limitations and the satisfaction of
certain conditions. When available, the Yorkville Equity Facility Financing Agreement provides an opportunity to actively manage the cash needs of the Company more
closely.  Historically,  cash  has  generally  been  available  to  the  Company  through  private  placements  of  equity  for  which  the  timing  did  not  always  coincide  with  the
Company’s  cash  needs.  The  Company  may  utilize  the  Yorkville  Equity  Facility  Financing  Agreement  to  potentially  generate  funds  at  a  time  when  they  are  in  need.
Alternatively, the Company can also utilize the Yorkville Equity Facility Financing Agreement for opportunistic share sales.

As of June 30, 2023, the Company had cash of $2.3 million and working capital of $0.2 million, compared to cash of $5.3 million and working capital of $0.6 million
on June 30, 2022. On September 1, 2023, the Company closed a non-brokered private placement (the “September 2023 Private Placement”) of units of the Company (the
“September 2023 Units”). A total of 250,000 September 2023 Units were issued at a price per September 2023 Unit of $4.00, for total gross proceeds to the Company of
$1.0  million.  Each  September  2023  Unit  consists  of  one  Common  Share  and  one  Common  Share  purchase  warrant  (“September  2023 Warrant”).  Each  September  2023
Warrant entitles the holder to acquire one Common Share at a price of $4.60 at any time prior to September 1, 2025. In addition, On September 12 and September 15, 2023,
the Company issued 70,000 and 75,000 Common Shares, respectively, under the Yorkville Equity Facility Financing Agreement in exchange for $0.5 million in gross cash
proceeds. NioCorp intends to use the net proceeds from these September financing transactions for working capital and general corporate purposes, including to advance its
efforts to launch construction of the Elk Creek Project and move it to commercial operation.

We expect that the Company will operate at a loss for the foreseeable future. The Company’s current planned cash needs are approximately $11.8 million until June 30,

2024.

In  addition  to  outstanding  accounts  payable  and  short-term  liabilities,  our  average  monthly  planned  expenditures  through  June  30,  2024  are  expected  to  be
approximately $685,000 per month where approximately $390,000 is for corporate overhead and estimated costs related to securing financing necessary for advancement of
the Elk Creek Project. Approximately $295,000 per month is planned for expenditures relating to the advancement of the Elk Creek Project by NioCorp’s majority owned
subsidiary, ECRC. The Company’s ability to continue operations and fund our current work plan is dependent on management’s ability to secure additional financing.

The Company anticipates that it does not have sufficient cash on hand to continue to fund basic operations for the next twelve months, and additional funds totaling
$8.0 million to $9.0 million, net of funds raised from the September financing transactions discussed above, are likely to be necessary to continue advancing the project in
the areas of financing, permitting, and detailed engineering. While the Yorkville Equity Facility Financing Agreement may provide the Company with access to additional
capital, the Company may require additional capital to meet its cash need. Management is actively pursuing such additional sources of debt and equity financing, and while
it has been successful in doing so in the past, there can be no assurance it will be able to do so in the future.

Elk Creek property and lease commitments are $20,000 through June 30, 2024. To maintain our currently held properties and fund our currently anticipated general and
administrative costs and planned exploration and development activities at the Elk Creek Project for the fiscal year ending June 30, 2024, the Company will likely require
additional financing during the current fiscal year. Should such financing not be available in that timeframe, we will be required to reduce our activities and will not be able
to carry out all our presently planned activities at the Elk Creek Project.

On June 6, 2023, the Company announced that it had submitted an application to the Export-Import Bank of the United States (“EXIM”) for debt financing (the “EXIM
Financing”) to fund the project costs for the Elk Creek Project, under EXIM’s “Make More in America” initiative. The EXIM Financing is subject to, among other matters,
the

51

 
 
 
 
 
 
 
 
 
 
satisfactory completion of due diligence, the negotiation and settlement of final terms, and the negotiation of definitive documentation. There can be no assurance that the
EXIM Financing will be completed on the terms described herein or at all.

Except for potential funding under the Yorkville Equity Facility Financing, discussed above, and the potential exercise of Options and Warrants, we currently have no
further funding commitments or arrangements for additional financing at this time, and there is no assurance that we will be able to obtain any such additional financing on
acceptable terms, if at all. Pursuant to the Exchange Agreement, NioCorp is restricted from issuing equity or equity-linked securities (other than Common Shares) or any
preferred equity or non-voting equity if such issuance would adversely impact the rights of the holders of the shares of Class B common stock of ECRC, without the consent
of the holders of a majority of the shares of Class B common stock of ECRC. The Yorkville Convertible Debt Financing Agreement also contains certain covenants that,
among other things, limit NioCorp’s ability to use the proceeds from the Yorkville Convertible Debt Financing to repay related party debt or to enter into any variable rate
transaction, including issuances of equity or debt securities that are convertible into Common Shares at variable rates and any equity line of credit, ATM agreement or other
continuous offering of Common Shares, other than with Yorkville, subject to certain exceptions. Notwithstanding the restrictions set forth in the Exchange Agreement and
the Yorkville Convertible Debt Financing Agreement, there is significant uncertainty that we would be able to secure any additional financing in the current equity or debt
markets.  The  quantity  of  funds  to  be  raised  and  the  terms  of  any  proposed  equity  or  debt  financing  that  may  be  undertaken  will  be  negotiated  by  management  as
opportunities to raise funds arise. Management may to pursue funding sources of both debt and equity financing, including but not limited to the issuance of equity securities
in the form of Common Shares, Warrants, subscription receipts, or any combination thereof in units of the Company pursuant to private placements to accredited investors or
pursuant to public offerings in the form of underwritten/brokered offerings, registered direct offerings, or other forms of equity financing and public or private issuances of
debt securities including secured and unsecured convertible debt instruments or secured debt project financing. Management does not currently know the terms pursuant to
which  such  financings  may  be  completed  in  the  future,  but  any  such  financings  will  be  negotiated  at  arm’s-length.  Future  financings  involving  the  issuance  of  equity
securities  or  derivatives  thereof  will  likely  be  completed  at  a  discount  to  the  then-current  market  price  of  the  Company’s  securities  and  will  likely  be  dilutive  to  current
shareholders. In addition, we could raise funds through the sale of interests in our mineral properties, although current market conditions and other recent worldwide events
have substantially reduced the number of potential buyers/acquirers of any such interests. However, we cannot provide any assurances that we will be able to be successful
in raising such funds.

Based on the conditions described within, management has concluded and the audit opinion and notes that accompany our consolidated financial statements for the year
ended June 30, 2023, disclose that substantial doubt exists as to our ability to continue in business. The consolidated financial statements included in this Annual Report on
Form 10-K have been prepared under the assumption that we will continue as a going concern. As defined under S-K 1300, we are a development stage issuer, and we have
incurred losses since our inception. We may not have sufficient cash, including option and warrant exercises subsequent to June 30, 2023, to fund normal operations and
meet debt obligations for the next twelve months without deferring payment on certain current liabilities and raising additional funds. Recent worldwide events have created
general global economic uncertainty as well as uncertainty in capital markets, supply chain disruptions, increased interest rates and inflation, and the potential for geographic
recessions. During fiscal year 2023, these events continued to create uncertainty with respect to overall project funding and timelines. We believe that the going concern
uncertainty cannot be alleviated with confidence until the Company has entered into a business climate where funding of its planned ongoing operating activities is secured.
Therefore, these factors raise substantial doubt as to our ability to continue as a going concern.

We have no exposure to any asset-backed commercial paper. Other than cash held by our subsidiaries for their immediate operating needs in Colorado and Nebraska, all
of our cash reserves are on deposit with major U.S. and Canadian chartered banks. We do not believe that the credit, liquidity, or market risks with respect thereto have
increased as a result of the current market conditions. However, in order to achieve greater security for the preservation of our capital, we have, of necessity, been required to
accept lower rates of interest, which has also lowered our potential interest income.

Operating Activities

During the year ended June 30, 2023, the Company’s operating activities consumed $17.3 million of cash (2022: $6.2 million and 2021: $4.7 million). The cash used in
operating activities for fiscal year 2023 reflects the Company’s funding of losses of $40.1 million, the net fair value losses related to the Private Warrants and the Earnout
Shares liabilities, share-based compensation, and other non-cash transactions. Overall, operational outflows during fiscal year 2023 increased from the corresponding period
of  2022  due  to  cash  expenses  related  to  the Transactions  and  an  increase  in  exploration-related  spending  at  the  Elk  Creek  Project.  Overall,  fiscal  year  2023  operational
outflows were higher than fiscal year 2022 due primarily to increased exploration expenditures. Going forward, the Company’s working capital requirements are expected to
increase substantially in connection with the development of the Elk Creek Project.

Investing Activities

The Company had minimal investing activities during the years ended June 30, 2023 and 2022, respectively.

Financing Activities

Net  cash  provided  by  financing  activities  was  $14.6  million  in  fiscal  year  2023  (2022:  $4.3  million  and  2021:  $18.1  million).  This  increase  in  financing  inflows

primarily reflects the timing of cash inflows from the financing transactions disclosed below.

The following is a discussion of significant financing transactions for fiscal year 2023:

● On February 28, 2023, the non-revolving credit facility agreement, dated January 16, 2017, as amended, with Mark Smith, our Chief Executive Officer, President,
and Executive Chairman (the “Smith Credit Agreement”) was amended to increase the borrowing limit to $4.0 million from the previous limit of $3.5 million. The
Company subsequently drew down $1.13 million under the Smith Credit Agreement. On March 22, 2023, the Company repaid Mr. Smith $2.0 million, representing
$159,000 of interest and $1.84 million of principal borrowed under the Smith Credit Agreement. This repayment was made out of funds transferred to the Company
from the GXII trust account on the Closing Date. Subsequently, on May 31, 2023, the Company repaid Mr. Smith $1.31 million, representing $24,000 of interest
and the remaining principal balance outstanding of $1.29 million.

● In connection with the GXII Transaction, on January 26, 2023, NioCorp and Yorkville entered into the Yorkville Convertible Debt Financing Agreement, which

was subsequently amended on February 24, 2023.

Pursuant to the Yorkville Convertible Debt Financing Agreement, at the Closing, Yorkville advanced a total amount of $15.36 million to NioCorp in consideration
of  the  issuance  by  NioCorp  to Yorkville  of  (i)  $16.0  million  aggregate  principal  amount  of  Convertible  Debentures  and  (ii)  the  Financing  Warrants,  which  are
exercisable for up to 1,789,267 Common Shares for cash or, if at any time there is no effective registration statement registering, or no current prospectus available
for, the resale of the underlying Common Shares, on a cashless basis, at the option of the holder, at a price per Common Share of approximately $8.9422, subject to
adjustment to give effect to any stock dividend, stock split, reverse stock split or similar transaction.

Each Convertible Debenture issued under the Yorkville Convertible Debt Financing Agreement is an unsecured obligation of NioCorp, matures on September 17,
2024, which maturity may be extended for one six-month period in certain circumstances at the option of NioCorp, and incurs a simple interest rate obligation of
5.0% per annum (which will increase to 15.0% per annum upon the occurrence of an event of default). The outstanding principal amount of, accrued and unpaid
interest, if any, on, and premium, if any, on the Convertible Debentures must be paid by NioCorp in cash when the same becomes due and payable under the terms
of the Convertible Debentures at their stated maturity, upon their redemption or otherwise.

Subject to certain limitations contained within the Yorkville Convertible Debt Financing Agreement and the Convertible Debentures, including those as described
below, holders of the Convertible Debentures will be entitled to convert the principal amount of, and accrued and unpaid interest, if any, on each Convertible

53

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Debenture, in whole or in part, from time to time over their term, into a number of Common Shares equal to the quotient of the principal amount and accrued and
unpaid interest, if any, being converted divided by the Conversion Price. The “Conversion Price” means, as of any Conversion Date (as defined below) or other
date of determination, the greater of (i) 90% of the average of the daily U.S. dollar volume-weighted average price of the Common Shares on the principal U.S.
market for the Common Shares as reported by Bloomberg Financial Markets during the five consecutive trading days immediately preceding the date on which the
holder exercises its conversion right in accordance with the requirements of the Yorkville Convertible Debt Financing Agreement (the “Conversion Date”) or other
date of determination, but not lower than the Floor Price (as defined below), and (ii) the five-day volume-weighted average price of the Common Shares on the
TSX (or on the principal U.S. market if the majority of the trading volume and value of the Common Shares occurred on Nasdaq during the relevant period) for the
five consecutive trading days immediately prior to the Conversion Date or other date of determination less the maximum applicable discount allowed by the TSX.
The “Floor Price” means a price of $2.1435 per share, which is equal to the lesser of (a) 30% of the average of the daily volume-weighted average price of the
Common  Shares  on  the  principal  U.S.  market  for  the  Common  Shares  as  reported  by  Bloomberg  Financial  Markets  during  the  five  consecutive  trading  days
immediately  preceding  the  Debenture  Closing  and  (b)  30%  of  the  average  of  the  volume-weighted  average  price  of  the  Common  Shares  on  the  principal  U.S.
market  for  the  Common  Shares  as  reported  by  Bloomberg  Financial  Markets  during  the  five  consecutive  trading  days  immediately  following  the  Debenture
Closing, subject to certain adjustments to give effect to any stock dividend, stock split, reverse stock split, recapitalization or similar event.

The  terms  of  the  Convertible  Debentures  restrict  the  number  of  Convertible  Debentures  that  may  be  converted  during  each  calendar  month  by  Yorkville  at  a
Conversion Price below a fixed price equal to approximately $8.9422 (i.e., the quotient of $10.00 divided by 1.11829212 (being the number of Common Shares
that  were  exchanged  for  each  share  of  GXII  at  the  Closing,  after  giving  effect  to  the  Reverse  Stock  Split)),  subject  to  adjustment  to  give  effect  to  any  stock
dividend, stock split, reverse stock split, recapitalization or similar event. The Convertible Debentures are subject to customary anti-dilution adjustments.

The  terms  of  the  Convertible  Debentures  restrict  the  conversion  of  Convertible  Debentures  by Yorkville  if  such  a  conversion  would  cause Yorkville  to  exceed
certain beneficial ownership thresholds in NioCorp or such a conversion would cause the aggregate number of Common Shares issued pursuant to the Yorkville
Convertible Debt Financing Agreement to exceed the thresholds for issuance of Common Shares under the rules of the TSX and Nasdaq, unless prior shareholder
approval is obtained.

Pursuant to the terms of the Convertible Debentures, following certain trigger events, and until a subsequent cure event, NioCorp will be required to redeem $1.125
million aggregate principal amount of Convertible Debentures (the “Triggered Principal Amount”) each month by making cash payments to the Investors, on a pro
rata  basis,  in  an  amount  equal  to  the  Triggered  Principal Amount,  plus  accrued  and  unpaid  interest  thereon,  if  any,  plus  a  redemption  premium  of  7%  of  the
Triggered Principal Amount. Such monthly prepayments under the terms of the Convertible Debentures are triggered (i) at the time when NioCorp has issued 95%
of the total amount of Common Shares pursuant to the Yorkville Convertible Debt Financing that it may issue under applicable TSX and Nasdaq rules or (ii) when
NioCorp has delayed or suspended the effectiveness or use of the Convertible Debt Financing Registration Statement for more than 20 consecutive calendar days,
and such monthly prepayment obligations will continue until, with respect to (i) above, shareholder approval is obtained or, with respect to (ii) above, the Investors
may once again resell Common Shares under the Convertible Debt Financing Registration Statement, respectively.

● In connection with the GXII Transaction, on January 26, 2023, the Company and Yorkville entered into the Yorkville Equity Facility Financing Agreement.

Pursuant to the Yorkville Equity Facility Financing Agreement, Yorkville has committed to purchase up to $65.0 million of our Common Shares (the “Commitment
Amount”),  at  our  direction  from  time  to  time  for  a  period  commencing  upon  the  Closing  Date  and  ending  on  the  earliest  of  (i)  the  first  day  of  the  month  next
following the 36-month anniversary of the Closing, (ii) the date on which Yorkville shall have made payment

54

 
 
 
 
 
 
 
 
of the full Commitment Amount and (iii) the date that the Yorkville Equity Facility Financing Agreement otherwise terminates in accordance with its terms (the
“Commitment Period”), subject to certain limitations and the satisfaction of the conditions in the Yorkville Equity Facility Financing Agreement. Pursuant to the
terms of the Yorkville Equity Facility Financing Agreement, we issued 81,213 of our Common Shares (the “Commitment Shares”) to Yorkville as consideration for
its  irrevocable  commitment  to  purchase  Common  Shares  under  the  Yorkville  Equity  Facility  Financing  Agreement.  Yorkville  has  since  resold  all  of  the
Commitment  Shares.  On  June  9,  2023,  we  issued  and  sold  100,000  Common  Shares  to  Yorkville  under  the  Yorkville  Equity  Facility  Financing  Agreement.
Additionally, we are required to pay Yorkville an aggregate fee of $1,500,000 in cash (the “Cash Fee”), including $500,000 that we paid on the Closing Date and an
additional $250,000 we have paid as of June 30, 2023. We will pay the remaining $750,000 balance in installments over a 12-month period following the Closing
Date, provided that, we will have the right to prepay without penalty all or part of the remaining installments of the Cash Fee at any time. The Common Shares that
may be sold pursuant to the Yorkville Equity Facility Financing Agreement would be purchased by Yorkville at a purchase price equal to 97% of the daily volume-
weighted average price of the Common Shares on Nasdaq or such other principal U.S. market for the Common Shares if the Common Shares are ever listed or
traded on the New York Stock Exchange or the NYSE American as reported by Bloomberg Financial Markets (or, if not available, a similar service provider of
national recognized standing) during the applicable pricing period, which is a period during a single trading day or a period of three consecutive trading days, at the
Company’s option and subject to certain restrictions, in each case, defined based on when an Advance Notice (as defined in the Yorkville Equity Facility Financing
Agreement) is submitted, subject to certain limitations.

As of June 30, 2023, 100,000 Common Shares, representing $488,080 in net proceeds, had been issued under the Yorkville Equity Facility Financing Agreement.

● On April 28, 2023, the Company issued and sold 314,465 Common Shares in a registered direct offering at a price of $6.36 per share. Net proceeds to the Company
from the offering were approximately $1.8 million. NioCorp intends to use the net proceeds from the offering for working capital and general corporate purposes,
including to advance its efforts to launch construction of the Elk Creek Project and move it to commercial operation.

The following is a discussion of significant financing transactions for fiscal year 2022:

● On June 30, 2022, the Company closed a non-brokered private placement (the “June 2022 Private Placement”) of units (the “June 2022 Units”) of the Company. A
total of 4,981,035 June 2022 Units were issued at a price per June 2022 Unit of C$0.96, for total gross proceeds to the Company of approximately C$4.8 million.
Each June 2022 Unit consists of one Common Share and one common share purchase warrant (“June 2022 Warrant”). Each June 2022 Warrant entitles the holder to
acquire  one  Common  Share  at  a  price  of  C$1.10  at  any  time  prior  to  July  1,  2024.  Proceeds  of  the  June  2022  Private  Placement  will  be  used  for  continued
advancement of the Company’s Elk Creek Critical Minerals Project and for working capital and general corporate purposes. The Company paid cash commissions
of C$62,000 and 65,100 warrants (the “Finder Warrants”), having the same terms as the June 2022 Warrants, to finders outside of the United States. The Finder
Warrants were valued at C$18,000 using a risk-free rate of 3.2%, expected volatility of 64% and expected life of two years.

● On July 23, 2021, the Company repaid $358,000 to Mr. Smith, representing a partial principal repayment of $318,000 on the Smith Credit Agreement plus accrued

interest.

Cash Flow Considerations

The  Company  has  historically  relied  upon  debt  and  equity  financings  to  finance  its  activities.  Subject  to  the  restrictions  set  forth  in  the Yorkville  Convertible  Debt
Financing Agreement, the Company may pursue additional debt and/or equity financing in the medium term; however, there can be no assurance the Company will be able
to obtain any required financing in the future on acceptable terms.

55

 
 
 
 
 
 
 
 
 
 
The Company has limited financial resources compared to its proposed expenditures, no source of operating income, and no assurance that additional funding will be

available to it for current or future projects, although the Company has been successful in the past in financing its activities through the sale of equity securities.

The ability of the Company to arrange additional financing in the future will depend, in part, on the prevailing capital market conditions, and its success in developing
the  Elk  Creek  Project. Any  quoted  market  for  the  Common  Shares  may  be  subject  to  market  trends  generally,  notwithstanding  any  potential  success  of  the  Company  in
creating revenue, cash flows, or earnings, and any depression of the trading price of the Common Shares could impact its ability to obtain equity financing on acceptable
terms.

Historically, the Company has used net proceeds from issuances of Common Shares to provide sufficient funds to meet its near-term exploration and development plans
and  other  contractual  obligations  when  due.  However,  development  and  construction  of  the  Elk  Creek  Project  will  require  substantial  additional  capital  resources. This
includes near-term funding and, ultimately, funding for Elk Creek Project construction and other costs. See “Liquidity and Capital Resources” above, for the Company’s
discussion of arrangements related to possible future financings.

Debt Covenants

The Convertible Debentures contain events of default customary for instruments of their type (with customary grace periods, as applicable) and provide that, upon the
occurrence of an event of default arising from certain events of bankruptcy or insolvency with respect to NioCorp, all outstanding Convertible Debentures will become due
and payable immediately without further action or notice. If any other type of event of default occurs and is continuing, then any holder may declare all of its Convertible
Debentures to be due and payable immediately. The Company obtained a waiver from Yorkville with respect to any acceleration rights it may have under the Convertible
Debentures in connection with the restatements of the Company’s financial statements for the periods ended September 30, 2022, and December 31, 2022, and the delay in
filing the Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2023. The Yorkville Convertible Debt Financing Agreement also contains
certain covenants that, among other things, limit NioCorp’s ability to use the proceeds from the Yorkville Convertible Debt Financing to repay related party debt or to enter
into any variable rate transaction other than with Yorkville, subject to certain exceptions. The Company was in compliance with these covenants as of June 30, 2023.

Environmental

Our mining and exploration activities are subject to various federal and state laws and regulations governing the protection of the environment. We have made, and
expect to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures. As of June 30, 2023 and
2022, we had accrued $48,000 and $48,000, respectively, related to estimated environmental obligations.

Forward-Looking Statements

The foregoing discussion and analysis, as well as certain information contained elsewhere in this Annual Report on Form 10-K, contain “forward-looking statements”
within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, and are intended to be covered by the safe harbor created thereby. See the
discussion in “Forward-Looking Statements” in Item 1., “Business.”

Accounting Developments

For  a  discussion  of  Recently  Adopted  Accounting  Pronouncements  and  Recently  Issued  Accounting  Pronouncements,  see  Note  3  to  the  consolidated  financial

statements included in this Annual Report on Form 10-K.

Critical Accounting Estimates and Recent Accounting Pronouncements

Our significant accounting policies are described in Note 3 to the consolidated financial statements included in this Annual Report on Form 10-K. As described in Note
3, we are required to make estimates and assumptions that affect the reported amounts and related disclosures of assets, liabilities, revenue, and expenses. Our estimates are
based on our experience and our interpretation of economic, political, regulatory, and other factors that affect our

56

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
business prospects. Many of the inputs into our estimation process are subjective and are subject to uncertainty over time and therefore, actual results may differ significantly
from our estimates. Note 3 also discloses recent accounting pronouncements applicable to the Company.

We believe that our most critical accounting estimates are related to the carrying value of our long term assets; accounting for income taxes and the valuation of deferred
tax assets; and the valuation of warrants and earnout shares, as they require us to make assumptions that are highly uncertain at the time the accounting estimates are made
and changes in them are reasonably likely to occur from period to period. Management has discussed the development and selection of these critical accounting estimates
with the Audit Committee of our board of directors, and the Audit Committee has reviewed the disclosures presented below. In addition, there are other items within our
consolidated  financial  statements  that  require  estimation,  but  are  not  deemed  to  be  critical.  However,  changes  in  estimates  used  in  these  and  other  items  could  have  a
material impact on our consolidated financial statements.

Carrying Value of Long-Lived Assets

The  recoverability  of  the  carrying  values  of  mineral  properties  is  dependent  upon  economic  reserves  being  discovered  or  developed  on  the  properties,  permitting,
financing, start-up, and commercial production from, or the sale/lease of, or other strategic transactions related to these properties. Development and/or start-up of a project
will depend on, among other things, management’s ability to raise sufficient capital for these purposes. We assess the carrying cost of our mineral properties for impairment
whenever information or circumstances indicate the potential for impairment. Key inputs include events and circumstances such as our inability to obtain all the necessary
permits, changes in the legal status of our mineral properties, government actions, the results of exploration activities and technical evaluations and changes in economic
conditions,  including  the  price  of  commodities  or  input  prices.  Many  of  these  inputs  are  subjective  and  are  subject  to  uncertainty  over  time.  Such  evaluations  compare
estimated future net cash flows with our carrying costs and future obligations on an undiscounted basis. If it is determined that the estimated future undiscounted cash flows
are less than the carrying value of the property, an impairment loss will be recorded, measured by the amount by which the carrying amount of the assets exceeds the fair
value  of  the  assets.  Where  estimates  of  future  net  cash  flows  are  not  determinable  and  where  other  conditions  indicate  the  potential  for  impairment,  management  uses
available market information and/or third-party valuation experts to assess if the carrying value can be recovered and to estimate fair value.

We review and evaluate our long-lived assets, other than mineral properties, for impairment when events or changes in circumstances indicate that the related carrying
amounts may not be recoverable. An impairment loss is measured and recorded based on the estimated fair value of the long-lived assets being tested for impairment and
their carrying amounts.

Income Taxes

We have assets, hold interests, and conduct activities in the U.S. and Canada and are subject to their tax regimes. Tax laws are complex and continue to evolve. While
we have a history of losses, our assumptions made in tax returns are subject to review and interpretation by taxing authorities and could be modified. Management judgment
is required in determining our provision for income taxes, our deferred tax assets and liabilities, and any valuation allowance recorded against our deferred tax assets. We
consider factors such as the cumulative income or loss in recent years; reversal of deferred tax liabilities; projected future taxable income exclusive of temporary differences;
the character of the income tax asset, including income tax positions; tax planning strategies and the period over which we expect the deferred tax assets to be recovered in
the determination of the valuation allowance. In the event that actual results differ from these estimates or we adjust our estimates in the future, we may need to adjust our
valuation allowance, which could materially impact our financial position and results of operations.

57

 
 
 
 
 
 
 
 
 
Earnout Shares and Private Warrants

The fair values of our Earnout Shares liability and Private Warrants liability were determined using various significant unobservable inputs, including a discount rate
and our best estimate of expected volatility and expected holding periods. Changes in the estimated fair values of these liabilities may have material impacts on our results of
operations in any given period, as any increases in these liabilities have a corresponding negative impact on our U.S. GAAP results of operations. See Note 10 and 11c to our
consolidated financial statements included in this Annual Report on Form 10-K for additional details.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk

The Company’s exposure to changes in market interest rates, relates primarily to the Company’s earned interest income on cash deposits and short-term investments.
The Company maintains a balance between the liquidity of cash assets and the interest rate return thereon. The carrying amount of financial assets, net of any provisions for
losses, represents the Company’s maximum exposure to credit risk.

Foreign currency exchange risk

The company incurs expenditures in both U.S. and Canadian dollars. Canadian dollar expenditures are primarily related to engineering and metallurgical expenses, as
well as certain professional services. As a result, currency exchange fluctuations may impact the costs of our operating activities. To reduce this risk, we maintain sufficient
cash balances in Canadian dollars to fund expected near-term expenditures.

Commodity price risk

The Company is exposed to commodity price risk related to the elements associated with the Elk Creek Project. A significant decrease in the global demand for these
elements  may  have  a  material  adverse  effect  on  our  business.  The  Elk  Creek  Project  is  not  in  production,  and  the  Company  does  not  currently  hold  any  commodity
derivative positions.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

Shareholders and Board of Directors
NioCorp Developments Ltd.
Centennial, Colorado

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of NioCorp Developments, Ltd. (the “Company”) as of June 30, 2023 and 2022, the related consolidated
statements  of  operations  and  comprehensive  loss,  shareholders’  (deficit)  equity  and  redeemable  noncontrolling  interest,  and  cash  flows  for  each  of  the  three  years  in  the
period ended June 30, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements
present fairly, in all material respects, the financial position of the Company at June 30, 2023 and 2022, and the results of its operations and its cash flows for each of the
three years in the period ended June 30, 2023, in conformity with accounting principles generally accepted in the United States of America.

Going Concern Uncertainty

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  as  a  going  concern. As  discussed  in  Note  4  to  the
consolidated  financial  statements,  the  Company  has  an  accumulated  deficit  and  suffered  recurring  losses  without  any  current  revenue  generating  operations.  These
conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 4.
The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to
perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting
but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

60

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

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required
to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our
especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial
statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts
or disclosures to which they relate.

Certain Financing Transactions

As described in Notes 1 and 9 to the consolidated financial statements, the Company entered into the following financing transactions during the year ended June 30, 2023:

● On September 25, 2022, the Company and Lind Global Asset Management III, LLC (“Lind”) entered into the waiver and consent agreement (the “Lind Consent”).
As consideration for entering into the Lind Consent, Lind received, amongst other things: the right to receive a cash payment; and the right to receive additional
warrants (the “Contingent Consent Warrants”) if certain contingencies are met on the date that is 18 months following the closing date.

● On  January  26,  2023,  the  Company  entered  into  a  definitive  agreement  with  YA  II  PN,  Ltd.,  an  investment  fund  managed  by  Yorkville Advisors  Global,  LP
(together  with  YA  II  PN,  Ltd.,  “Yorkville”).  Pursuant  to  the  definitive  agreement,  at  the  closing,  Yorkville  advanced  a  total  amount  of  $15.36  million  to  the
Company in consideration for $16 million aggregate principal amount of unsecured convertible debentures (the “Yorkville Convertible Debt”) and common share
purchase warrants (the “Financing Warrants”).

We identified the accounting treatment of these transactions and the inputs and valuation model used in estimating the fair value of the Contingent Consent Warrants as a
critical  audit  matter.  The  principal  considerations  for  our  determination  were:  (i)  the  evaluation  of  the  accounting  treatment  for  the  Lind  Consent  as  to  whether  this
agreement resulted in a debt modification or extinguishment based on the analysis of cash flows, (ii) the evaluation of the potential derivatives that may require bifurcation

audit effort required to address these matters, including the extent of specialized skills or knowledge needed.

The primary procedures we performed to address this critical audit matter included:

● Reviewing and analyzing the terms of the agreements associated with each transaction.

● Reviewing and analyzing the changes in cash flows for the Lind financing transaction.

● Utilizing personnel with specialized knowledge and skills in the relevant technical accounting guidance to assist in: (i) evaluating relevant contract terms of the

financing transactions in relation to the appropriate accounting literature, and (ii) assessing the appropriateness of conclusions reached by the Company.

● Utilizing personnel with specialized knowledge and skill to assist in analyzing the Company’s inputs and valuation model used in estimating the fair value for the

Contingent Consent Warrants.

GX Acquisition Corp. II Transaction

As discussed in Notes 1, 5, 10, and 11 on March 17, 2023 (the “Closing Date”), the Company closed the GXII Transaction with GX Acquisition Corp. II (“GXII”), pursuant
to the Business Combination Agreement, dated September 25, 2022 (the “Business Combination Agreement”).

In connection with the closing, pursuant to the Business Combination Agreement, the Company assumed the GXII Warrant Agreement and each GXII Warrant thereunder
that was issued and outstanding immediately prior to the Closing Date was converted into one Company assumed warrant. The Company’s private warrants are required to
be accounted for as a liability and are subject to remeasurement at each balance sheet date, with a June 30, 2023 value of $3.3 million.

Certain shares of Class B common stock of Elk Creek Resource Corporation (“ECRC”) (the “Earnout Shares”) are subject to certain vesting conditions. The Earnout Shares
are required to be accounted for as a liability and are subject to remeasurement at each balance sheet date, with a June 30, 2023 value of $10.5 million.

We identified the accounting treatment of the GXII Transaction and the inputs and valuation models used in estimating the fair value of the private warrants and Earnout
Shares included in the GXII Transaction as a critical audit matter. The principal considerations for our determination were: (i) the evaluation of the accounting treatment for
the GXII Transaction, including the accounting for the private warrants and Earnout Shares, and (ii) the evaluation of the inputs and valuation models used in estimating the
fair value of both the private warrants and Earnout Shares. Auditing these elements involved especially challenging auditor judgment

due to the nature and extent of audit effort required to address these matters, including the extent of specialized skills or knowledge needed.

The primary procedures we performed to address this critical audit matter included:

● Reviewing and analyzing the terms of the agreements associated with the GXII Transaction.

● Utilizing personnel with specialized knowledge and skills in the relevant technical accounting guidance to assist in: (i) evaluating relevant contract terms in relation

to the appropriate accounting literature, and (ii) assessing the appropriateness of conclusions reached by the Company.

● Utilizing personnel with specialized knowledge and skill to assist in analyzing the Company’s inputs and valuation models used in estimating the fair value for both

the private warrants and Earnout Shares.

(expressed in thousands of U.S. dollars, except share and per share data)

1. DESCRIPTION OF BUSINESS

NioCorp Developments Ltd. (the “Company” or “NioCorp”) was incorporated on February 27, 1987, under the laws of the Province of British Columbia and currently
operates  in  one  reportable  operating  segment  consisting  of  exploration  and  development  of  mineral  deposits  in  North  America,  specifically,  the  Elk  Creek
Niobium/Scandium/Titanium property (the “Elk Creek Project”) located in southeastern Nebraska.

As  further  discussed  in  Notes  5,  9,  10,  and  11,  on  March  17,  2023  (the  “Closing  Date”),  the  Company  closed  the  GXII  Transaction  (as  defined  below)  with  GX
Acquisition  Corp.  II  (“GXII”),  pursuant  to  the  Business  Combination Agreement,  dated  September  25,  2022  (the  “Business  Combination Agreement”),  among  the
Company, GXII and Big Red Merger Sub Ltd (the “Closing”). At the Closing, the Company also closed convertible debt financings (the “Yorkville Convertible Debt
Financing”) with YA II PN, Ltd., an investment fund managed by Yorkville Advisors Global, LP (together with YA II PN, Ltd., “Yorkville”), and the standby equity
purchase  facility  with Yorkville  (the  “Yorkville  Equity  Facility  Financing”  and,  together  with  the Yorkville  Convertible  Debt  Financing,  the  “Yorkville  Financings”)
became effective. The transactions contemplated by the Business Combination Agreement, including the GXII Transaction, the Yorkville Financings and the Reverse
Stock Split (as defined below), are referred to, collectively, as the “Transactions.”

The GXII Transaction is being accounted for as an equity raise transaction in accordance with generally accepted accounting principles of the United States of America
(“U.S. GAAP”). Under this method of accounting, GXII is treated as the “acquired” company for financial reporting purposes. Accordingly, the GXII Transaction is
treated as the equivalent of NioCorp issuing common shares, no par value, of the Company (“Common Shares”) for the assets and liabilities of GXII. The net assets of
GXII are stated at historical cost, with no goodwill or other intangible assets recorded.

These  consolidated  financial  statements  have  been  prepared  on  a  going  concern  basis  that  contemplates  the  realization  of  assets  and  discharge  of  liabilities  at  their
carrying values in the normal course of business for the foreseeable future. These consolidated financial statements do not reflect any adjustments that may be necessary
if the Company is unable to continue as a going concern. 

The  Company  currently  earns  no  operating  revenues  and  will  require  additional  capital  in  order  to  advance  the  Elk  Creek  Project  to  construction  and  commercial
operation. As  further  discussed  in  Note  4,  these  matters  raised  substantial  doubt  about  the  Company’s  ability  to  continue  as  a  going  concern,  and  the  Company  is
dependent upon the generation of profits from mineral properties, obtaining additional financing and maintaining continued support from its shareholders and creditors.

2. BASIS OF PREPARATION

a) Basis of Preparation and Consolidation

These  consolidated  financial  statements  have  been  prepared  in  conformity  with  U.S.  GAAP  and  the  rules  and  regulations  of  the  U.S.  Securities  and  Exchange
Commission.  The  consolidated  financial  statements  include  the  consolidated  accounts  of  the  Company  and  its  wholly  owned  subsidiaries  with  all  significant
intercompany transactions eliminated. Certain transactions include reference to Canadian dollars (“C$”) where applicable.

b) Use of Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported
amounts of expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to the deferred income tax asset valuations,
convertible  debt  valuations,  earnout  valuation,  warrant  liabilities,  and  share-based  compensation.  The  Company  bases  its  estimates  and  assumptions  on  current
facts,  historical  experience,  and  various  other  factors  that  it  believes  to  be  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making
judgments about the other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent
there are material differences between estimates and the actual results, future results of operations will be affected. 

3. SIGNIFICANT ACCOUNTING POLICIES

a) Development Stage Issuer

The Company is considered to be a development stage issuer under Subpart 1300 of Regulation S-K of the United States Securities Act of 1933, as amended (“S-K
1300”), and it devotes substantially all of its efforts to acquiring and exploring mining interests that management believes should eventually provide sufficient net
profits to sustain the Company’s existence. Until such interests are engaged in commercial production, the Company will continue to seek additional funding to
support the completion of its exploration and development activities. The Company’s activities are subject to significant risks and uncertainties, including its ability
to secure sufficient funding to continue operations, to obtain proven and probable reserves, to comply with industry regulations and obtain permits necessary for
development of the Elk Creek Project, as well as environmental risks and market conditions.

b) Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, cash in banks, investments in certificates of deposit with original maturities of 90 days or less, and money market
funds. The Company maintains the majority of its cash balances with two financial institutions. Accounts at banks in the United States (“U.S.”) are insured by the
Federal  Deposit  Insurance  Corporation  (“FDIC”)  up  to  $250,  while  accounts  at  banks  in  Canada  are  insured  by  the  Canada  Deposit  Insurance  Corporation
(“CDIC”) up to C$100. At June 30, 2023 and 2022, the Company had $1,717 and $4,721 in excess of the FDIC and CDIC insured limits, respectively.

c) Foreign Currency Translation

Functional and reporting currency
Items included in the financial statements of each of the Company’s entities are measured using the currency of the primary economic environment in which the
entity operates (“the functional currency”).

The reporting currency for these consolidated financial statements is U.S. dollars.

Change in functional currency
Prior to March 17, 2023, the Company’s functional currency was the Canadian dollar. The Company re-assessed its functional currency and determined that on
March 17, 2023, its functional currency changed from the Canadian dollar to the U.S. dollar based on significant changes in economic facts and circumstances in
our organization. The change in functional currency was accounted for prospectively from March 17, 2023 and prior-period consolidated financial statements were
not restated for the change in functional currency.

NioCorp Developments Ltd.
Notes to Consolidated Financial Statements
June 30, 2023
(expressed in thousands of U.S. dollars, except share and per share data)

For both monetary and non-monetary assets and liabilities, translated balances as of March 17, 2023 became the new accounting basis. The exchange rate on the
date of change became the historical rate at which non-monetary assets and liabilities were translated in subsequent periods. There was no effect on the cumulative
translation adjustment on the consolidated basis. Previously recorded cumulative translation adjustments were not reversed.

The functional currency for the Company’s Canadian subsidiary, 0896800 BC Ltd., which has no independent operations from its parent, also changed from the
Canadian dollar to the U.S. dollar. The functional currency for Elk Creek Resources Corp. remains as the U.S. dollar.

Transactions in foreign currency 
Transactions  made  in  a  currency  other  than  the  functional  currency  are  remeasured  to  the  functional  currency  at  exchange  rates  at  the  dates  of  the  transactions.
Monetary assets and liabilities denominated in foreign currencies at the reporting date are remeasured to the functional currency at the exchange rate at that date and
non-monetary assets and liabilities are remeasured at historical rates. Foreign currency translation gains and losses are included in profit or loss.

Translation to reporting currency 
Translation gains and losses from the application of the U.S. dollar as the reporting currency for all periods prior to March 17, 2023 (when the Canadian dollar was
the  functional  currency)  are  included  as  part  of  cumulative  currency  translation  adjustment,  which  is  reported  as  a  component  of  shareholders’  equity  under
accumulated other comprehensive loss.

d) Mineral Properties

Mineral property acquisition costs, including indirectly related acquisition costs, are capitalized when incurred. Acquisition costs include cash consideration and the
fair market value of Common Shares issued as consideration. Properties acquired under option agreements, whereby payments are made at the sole discretion of the
Company,  are  capitalized  as  mineral  property  acquisition  costs  at  such  time  as  the  payments  are  made.  Exploration  costs  are  expensed  as  incurred.  When  it  is
determined that a mining deposit can be economically and legally extracted or produced based on established proven and probable reserves under S-K 1300, and the
Board of Directors has approved the commencement of formal development activities, development costs related to such reserves and incurred after such board
approval will be considered for capitalization. The establishment of proven and probable reserves is based on results of feasibility studies, which indicate whether a
property is economically feasible. Upon commencement of commercial production, capitalized costs will be amortized over their estimated useful lives or units of
production,  whichever  is  a  more  reliable  measure.  Capitalized  amounts  relating  to  a  property  that  is  abandoned  or  otherwise  considered  uneconomic  for  the
foreseeable future are written off.

The recoverability of the carrying values of mineral properties is dependent upon economic reserves being discovered or developed on the properties, permitting,
financing, start-up, and commercial production from, or the sale/lease of, or other strategic transactions related to these properties. Development and/or start-up of a
project will depend on, among other things, management’s ability to raise sufficient capital for these purposes. We assess the carrying cost of our mineral properties
for impairment whenever information or circumstances indicate the potential for impairment. This would include events and circumstances such as our inability to
obtain  all  the  necessary  permits,  changes  in  the  legal  status  of  our  mineral  properties,  government  actions,  the  results  of  exploration  activities  and  technical
evaluations and changes in economic conditions, including the price of commodities or input prices. Such evaluations compare estimated future net cash flows with
our carrying costs and future obligations on an undiscounted basis. If it is determined that the estimated future undiscounted cash flows are less than the carrying
value of the property, an impairment loss will be recorded. Where estimates of future net cash flows are not determinable and where other conditions indicate the
potential for impairment, management uses available market information and/or third-party valuation experts to assess if the carrying value can be recovered and to
estimate fair value. There was no impairment recorded to mineral properties as of June 30, 2023 or 2022, respectively.

e) Long Lived Assets

Long-lived assets, other than mineral properties, held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable.

NioCorp Developments Ltd.
Notes to Consolidated Financial Statements
June 30, 2023
(expressed in thousands of U.S. dollars, except share and per share data)

For purposes of evaluating the recoverability of long-lived assets, the recoverability test is performed using undiscounted net cash flows related to the long-lived
assets. If such assets are considered to be impaired, the impairment recognized is measured by the amount by which the carrying amount of the assets exceeds the
fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. There was no impairment recorded to
long-lived assets as of June 30, 2023 or 2022, respectively.

f) Leases

Under Accounting Standards Codification (“ASC”) 842, “Leases,” we determine if a contractual arrangement is, or contains, a lease at the inception date. Right-of-
use  (“ROU”)  assets  and  liabilities  related  to  operating  leases  are  separately  reported  in  the  consolidated  balance  sheets. The  Company  currently  has  no  finance
leases.

ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the future lease payments over the lease term. When
the rate implicit to the lease cannot be readily determined, we utilize our incremental borrowing rate in determining the present value of the future lease payments.
The incremental borrowing rate is derived from information available at the lease commencement date and represents the rate of interest that a lessee would have to
pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term in a similar economic environment. Operating lease ROU assets
also  include  any  cumulative  prepaid  or  accrued  rent  when  the  lease  payments  are  uneven  throughout  the  lease  term.  The  ROU  assets  and  lease  liabilities  may
include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

Lease liabilities are increased by interest and reduced by payments each period, and the ROU asset is amortized over the lease term. For operating leases, interest on
the lease liability and the amortization of the ROU asset result in straight-line rent expense over the lease term. Variable lease expenses are recorded when incurred.

g) Warrants

We  apply  relevant  accounting  guidance  for  warrants  to  purchase  our  stock  based  on  the  nature  of  the  relationship  with  the  counterparty.  For  warrants  issued  to
investors or lenders in exchange for cash or other financial assets, we follow guidance issued within ASC 480, Distinguishing Liabilities from Equity, and ASC
Topic 815, Derivatives and Hedging, (“ASC 815”) to assist in the determination of whether the warrants should be classified as liabilities or equity. The fair value
of warrants is estimated using Black Scholes modeling or Monte Carlo modeling, depending on the settlement features embedded in the warrant. Inputs under both
models include inputs such as NioCorp’s Common Share price, the risk-free interest rate, the expected term, the volatility, and the dividend rate. Warrants that are
determined to require liability classifications are measured at fair value upon issuance and are subsequently remeasured to their then fair value at each subsequent
reporting period with changes in fair value recorded in current earnings. Warrants that are determined to require equity classifications measured at fair value upon
issuance and are not subsequently remeasured unless they are required to be reclassified.

h) Earnout Shares

Earnout Shares are classified as a liability due to failure to meet the equity classification criteria under ASC 815-40. The fair value of the Earnout Shares on the date
of issuance and on each measurement date is estimated using a Monte Carlo simulation methodology, which includes inputs such as NioCorp’s Common Share
price, the risk-free interest rate, the expected term, the implied volatility underlying the Company’s Public Warrants, the dividend rate, the conversion price, and the
number of Earnout Shares outstanding. Assumptions used in the model are subjective and require significant judgment.

i)

Financial Instruments
The Company’s financial instruments consist of cash and cash equivalents, receivables, equity securities, accounts payable and accrued liabilities, convertible debt
and the related party loan. It is management’s opinion that the Company is not exposed to significant interest, currency or credit risks arising from its financial
instruments. The fair values of these instruments approximate their carrying value unless otherwise noted.

j) Concentration of Credit Risk

The financial instrument which potentially subjects the Company to credit risk is cash and cash equivalents, The Company holds investments or maintains available
cash primarily in two commercial banks located in Vancouver,

NioCorp Developments Ltd.
Notes to Consolidated Financial Statements

(expressed in thousands of U.S. dollars, except share and per share data)

British  Columbia  and  Santa  Clara,  California.  As  part  of  its  cash  management  process,  the  Company  regularly  monitors  the  relative  credit  standing  of  these
institutions.

k) Asset Retirement Obligation

The Company is subject to various government laws and regulations relating to environmental disturbances caused by exploration and evaluation activities. The
estimated costs associated with environmental remediation obligations are accrued in the period in which the liability is incurred if it is reasonably estimable or
known. Until such time that a project life is established, the Company records the corresponding cost as an exploration stage expense and has accrued $48 as an
accrued liability related to estimated obligations as of June 30, 2023 (2022 - $48).

Future reclamation and environmental-related expenditures are difficult to estimate in many circumstances due to the early-stage nature of the Elk Creek Project,
the uncertainties associated with defining the nature and extent of environmental disturbance, the application of laws and regulations by regulatory authorities and
changes in reclamation or remediation technology. The Company periodically reviews accrued liabilities for such reclamation and remediation costs as evidence
indicating  that  the  liabilities  have  potentially  changed  becomes  available.  Changes  in  estimates  are  reflected  in  the  consolidated  statement  of  operations  and
comprehensive loss in the period an estimate is revised.

l)

Income Taxes
Income taxes are provided based upon the liability method of accounting pursuant to ASC 740-10-25, “Income Taxes – Recognition.” Under the approach, deferred
income taxes are recorded to reflect the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting
amounts at each year-end. A valuation allowance is recorded against deferred tax assets if management does not believe the Company has met the “more likely than
not” standard imposed by ASC 740-10-25-5 to allow recognition of such an asset. ASC 740-10-50, “Income Taxes – Disclosure,” requires the Company to evaluate
its income tax positions and recognize a liability for uncertain tax positions that are not more likely than not to be sustained by tax authorities. As of June 30, 2023
and 2022, the Company believes it had no income tax uncertainties that required recognition of a liability. If the Company were to determine that uncertain tax
positions meet the criteria for recognition, an estimated liability and related interest and penalties would be recognized as income tax expense.

m) Reverse Stock Split

On March 17, 2023, the Company effected a reverse stock split (the “Reverse Stock Split”) on the basis of one (1) post-Reverse Stock Split Common Share for
every ten (10) pre-Reverse Stock Split Common Shares issued and outstanding, with any fractional shares resulting from the Reverse Stock Split rounded down to
the nearest whole share. Immediately after the Reverse Stock Split, there were 30,000,442 Common Shares issued and outstanding. All references to share and per
share amounts (excluding authorized shares) in the consolidated financial statements and accompanying notes have been retroactively restated to reflect the Reverse
Stock Split.

n) Redeemable Noncontrolling Interest

Redeemable Noncontrolling Interest refers to non-controlling interest associated with the Vested Shares that are redeemable upon the occurrence of an event that is
not  solely  within  the  Company’s  control  and  is  reported  in  the  mezzanine  section  between  total  liabilities  and  shareholders’  deficit,  as  temporary  equity  in  the
Company’s consolidated balance sheets. The Company’s non-controlling interest is redeemable at fair value, and no adjustment to the earnings per share numerator
is required because redemption at fair value is not considered an economic distribution different from other common stockholders.

o) Basic and Diluted Per Share Disclosure

Basic  earnings  (loss)  per  share  represents  net  earnings  (loss)  attributable  to  common  shareholders  divided  by  the  weighted  average  number  of  Common  Shares
outstanding  during  the  period. The  Company  considers Vested  Shares  and  Released  Earnout  Shares  (each  as  defined  in  Note  10),  to  be  participating  securities,
requiring  the  use  of  the  two-class  method.  Diluted  earnings  (loss)  per  share  represents  net  earnings  (loss)  attributable  to  common  shareholders  divided  by  the
weighted average number of Common Shares outstanding, inclusive of the dilutive impact of all potentially dilutive securities outstanding during the period, as
applicable.

The  Company  utilizes  the  weighted  average  method  to  determine  the  impact  of  changes  in  a  participating  security  on  the  calculation  of  loss  per  share.  The
following table sets forth the computation of the Company’s basic and diluted net loss per share attributable to common shareholders:

amounts have not been adjusted for the treasury stock method or weighted average outstanding calculations as required if the securities were dilutive.

(2) Earnout Shares (as defined below) are excluded as the vesting terms were not met as of the end of the reporting period.

p) Share Based Compensation

The Company grants stock options to directors, officers, employees, and business advisors. Option terms and vesting conditions are at the discretion of the Board of
Directors.  Prior  to  March  21,  2023,  the  option  exercise  price  was  equal  to  the  closing  market  price  on  The  Toronto  Stock  Exchange  (the  “TSX”)  on  the  day
preceding the date of grant. Effective March 21, 2023, the option exercise price is equal to the closing market price on the Nasdaq Stock Market LLC (“Nasdaq”)
on the day preceding the date of the grant.

The Company estimates the fair value of stock options using the Black-Scholes option pricing model. The Company recognizes forfeitures as they occur.

q) Recent Accounting Standards

Issued and Adopted
In August 2020, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, Debt - Debt with Conversion
and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”), which simplifies the
accounting for convertible instruments. ASU 2020-06 removes certain accounting models which separate the embedded conversion features from the host contract
for convertible instruments. Either a modified retrospective method of transition or a fully retrospective method of transition is permissible for the adoption of this
standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal

years. The Company adopted ASU 2020-06 on July 1, 2022, with no material effect on the Company’s current financial position, results of operations or financial
statement disclosures.

Issued and Not Effective
From time to time, new accounting pronouncements are issued by the FASB that are adopted by the Company as of the specified effective date. Unless otherwise
discussed, management believes that the impact of recently issued standards did not or will not have a material impact on the Company’s consolidated financial
statements upon adoption.

r) Revision of Financial Statements (Unaudited)

During the fourth quarter of fiscal year 2023, the Company determined that it had used an incorrect strike price while valuing the Private Warrants (as defined below in
Note 11c) at both the March 17, 2023, issuance date and as of March 31, 2023. This resulted in an overstatement of other operating expenses, at fair value, and an
understatement of change in fair value of warrant liabilities in condensed consolidated statement of operations and comprehensive loss for both the three- and nine-
month periods ended March 31, 2023. In addition, warrant liabilities, at fair value and accumulated deficit were overstated and understated, respectively, as of March
31, 2023.

The  Company  determined  that  these  errors  were  immaterial  to  the  previously  issued  consolidated  financial  statements,  and  as  such  no  restatement  was  necessary.
Periods not presented herein will be revised, as applicable, in future filings.

The effects of the revision on the previously issued consolidated financial statements are as follows:

The Company incurred a net loss of $40,080 for the year ended June 30, 2023 (2022 - $10,887 and 2021 - $4,824) and had an accumulated deficit of $150,477 as of
June 30, 2023. As a development stage issuer, the Company has not yet commenced its mining operations and accordingly does not generate any revenue. As of June 30,
2023, the Company had cash and cash equivalents of $2,341 which is not sufficient to fund normal operations for the next twelve months without deferring payment on
certain  liabilities  or  raising  additional  funds.  In  addition,  the  Company  will  be  required  to  raise  additional  funds  for  construction  and  commencement  of  operations.
These factors raise substantial doubt about the Company's ability to continue as a going concern.

The Company’s ability to continue operations and fund its expenditures, which have historically averaged approximately $2,350 per quarter over the preceding three-
year period, is dependent on management’s ability to secure additional financing. NioCorp expects to have access to up to $62,577 in net proceeds from the Yorkville
Equity  Facility  Financing  through April  1,  2026,  as  discussed  in  Note  11d.  Management  is  actively  pursuing  additional  sources  of  financing,  and  while  it  has  been
successful  in  doing  so  in  the  past,  there  can  be  no  assurance  it  will  be  able  to  do  so  in  the  future.  Other  than  the  potential  issuance  of  Common  Shares  under  the
Yorkville Equity Facility Financing Agreement, the Company did not have any further funding commitments or arrangements for additional financing as of June 30,
2023. These consolidated financial statements do not give effect to any adjustments required to realize the Company’s assets and discharge its liabilities in other than the
normal course of business and at amounts different from those reflected in the accompanying consolidated financial statements.

Recent worldwide events have created general global economic uncertainty as well as uncertainty in capital markets, supply chain disruptions, increased interest rates
and inflation, and the potential for geographic recessions. We believe this could have an adverse impact on our ability to obtain financing, development plans, results of
operations,  financial  position,  and  cash  flows  during  the  current  fiscal  year.  The  full  extent  to  which  these  events  and  our  precautionary  measures  may  continue  to
impact our business will depend on future developments, which continue to be highly uncertain and cannot be predicted at this time.

5. GXII TRANSACTION

Pursuant to the Business Combination Agreement, the following transactions (collectively, the “GXII Transaction”) occurred on the Closing Date:

● As a result of a series of transactions, GXII became an indirect, majority-owned subsidiary of NioCorp and changed its name to “Elk Creek Resources Corp”

(“ECRC”).

● As the parent company of the merged entity, NioCorp issued 1,753,821 post-Reverse Stock Split Common Shares in exchange for all of the Class A shares of
GXII issued and outstanding immediately prior to the Closing, including 83,770 Common Shares issued to BTIG, LLC in exchange for Class A shares of GXII
that it received as partial payment for advisory services.

● All of the Class B shares of GXII issued and outstanding immediately prior to the Closing (after giving effect to the surrender of certain Class B shares of GXII in
accordance with the Sponsor Support Agreement, dated September 25, 2022 (the “Sponsor Support Agreement”), among GX Sponsor II LLC (the “Sponsor”),
GXII,  NioCorp  and  the  other  persons  party  thereto)  were  converted  into  7,957,404  shares  of  Class  B  common  stock  of  GXII  (now  known  as  ECRC)  as  the

In October 2022, the Company entered into an agreement with the State of Nebraska (the “State”) to sell a strip of Company-owned land totaling approximately 1.27
acres located adjacent to State Highway 50 in connection with highway improvements to be completed by the State, for $21, inclusive of estimated fence replacement
costs. The Company retained ownership of the mineral rights associated with this 1.27-acre parcel. The Company recorded a gain on this sale of $13 in other gains in the
consolidated statement of operations and comprehensive loss.

7. MINERAL PROPERTIES

During the year ended June 30, 2011, the Company completed the acquisition of the Elk Creek property through a share exchange agreement with 0859404 BC Ltd, a
Canadian  company,  which  owned  all  the  issued  and  outstanding  shares  of  ECRC. The  Company  issued  1,899,053  Common  Shares  to  acquire  all  of  the  issued  and
outstanding shares of 0859404 BC Ltd. and issued 103,434 Common Shares as a finder’s fee with respect to the acquisition. The transaction did not meet the definition
of a business acquisition, as set forth in ASC 805, “Business Combinations,” and therefore was accounted for as a purchase of assets. The acquisition price was based on
the  market  value  of  the  Company’s  Common  Shares  on  the  closing  date  and  total  consideration  given  was  C$13,246,  including  associated  deferred  tax  impacts  of
C$4,736.

On April 23, 2021, ECRC formally closed the purchase of two parcels of land and associated buildings and mineral rights in Johnson County, Nebraska, associated with
the Elk Creek Project, pursuant to an Amended and Restated Option to Purchase, dated as of April 29, 2020 (the “Option Agreement”). Pursuant to the terms of the
Option Agreement, the Owner sold, transferred, conveyed and assigned all of the rights, privileges, title and interest in and to the real property to ECRC, including any
associated mineral rights. The Option Agreement provided for a purchase price calculated based on the appraised value per acre of the parcels of land, the mineral rights
and the structures erected on the land. The purchase price was approximately $6,300, including indirect costs of $57. Of this amount, $837 was allocated to land and
buildings and the remaining $5,468 was allocated to mineral properties as costs related to mineral rights acquisition.

In addition to the land and mineral rights currently owned by the Company, the property interests of Elk Creek include eight prepaid mineral exploration option-to-
purchase agreements and include a pre-determined buyout for permanent ownership of the mineral and/or surface rights. Terms of the agreements require no further
significant payments, and the Company may negotiate lease extensions or elect to purchase the mineral and/or surface rights any time. Agreements that allow for the
purchase of mineral rights contain provisions whereby the landowners would retain a 2% net smelter return.

Lind III Convertible Security

On February 16, 2021, the Company issued to Lind Global Asset Management III, LLC (“Lind”), an entity managed by The Lind Partners, the convertible security (the
“Lind III Convertible Security”) pursuant to the Convertible Security Funding Agreement, dated February 16, 2021, as amended by Amendment #1 to the Convertible
Security Funding Agreement, dated December 2, 2021, between the Company and Lind (as amended, the “Lind III Agreement”). The Lind III Convertible Security had
a face value of $11,700 (representing $10,000 in funding plus an implied 8.5% interest rate per annum for the term of the Lind III Convertible Security). After deducting
a $350 commitment fee as set forth in the Lind III Agreement, NioCorp received net proceeds of $9,650 from the funding of the Lind III Convertible Security. The
Company used a portion of the proceeds from the funding of the Lind III Convertible Security to purchase a key land parcel associated with the Company’s Elk Creek
Project, with the remainder spent for general corporate purposes.

The Lind III Convertible Security had a term of (i) 24 months or (ii) 30 calendar days after the date on which the face value of the Lind III Convertible Security is nil
due to such amount having been fully converted and/or fully repaid (including with any applicable premium) in accordance with the terms of the Lind III Agreement,
whichever is earlier.

Pursuant to the Lind III Agreement, Lind was entitled to convert the Lind III Convertible Security into Common Shares in monthly installments over its term at a price
per Common Share equal to 85% of the volume-weighted average price Common Shares on the TSX for the five trading days immediately preceding to the date on
which Lind provides notice to the Company of its election to convert. The Lind III Agreement provided that Common Shares issuable upon conversion, together with
the number of Common Shares issued upon exercise of Warrants, shall not exceed 4,358,800 Common Shares.

On  February  19,  2021,  in  connection  with  the  funding  and  issuance  of  the  Lind  III  Convertible  Security,  the  Company  issued  855,800  Common  Share  purchase
warrants, exercisable at a price per Common Share of C$9.70, expiring February 19, 2025 (the “Lind III Warrants”), to Lind pursuant to the Lind III Agreement.

The Company identified embedded derivatives in the Lind III Convertible Security that were evaluated to be immaterial at both the closing date and at June 30, 2022.

The Company allocated the net proceeds of $9,477 from the Lind III Convertible Security as follows:

●

●

$1,712 was allocated to Common Stock, representing the fair value of the Lind III Warrants based on the Black Scholes pricing model using a risk-free interest
rate of 0.40%, an expected dividend yield of 0%, a volatility of 51.60%, and an expected life of 4.0 years.

$7,938  was  allocated  to  the  convertible  debt  liability.  Transaction  costs  of  $173,  in  addition  to  a  commitment  fee  of  $350,  were  recognized  as  a  direct
deduction  from  the  debt  liability,  resulting  in  a  net  opening  balance  of  $7,765. This  balance  was  accreted  up  to  the  face  value  of  the  Lind  III  Convertible
Security  at  maturity  using  the  effective  interest  method  and  recorded  as  non-cash  interest  expense  in  the  consolidated  statement  of  operations  and
comprehensive loss.

Notes to Consolidated Financial Statements
June 30, 2023
(expressed in thousands of U.S. dollars, except share and per share data)

On September 25, 2022, the Company and Lind entered into the Waiver and Consent Agreement, dated September 25, 2022, between the Company and Lind (the “Lind
Consent”), which included the following principal terms: (i) the consent of Lind to the GXII Transaction disclosed in Note 5 and Yorkville Financings disclosed below
and in Note 11d, including all actions taken by NioCorp as set out in the Business Combination Agreement to permit the completion of the Transactions; (ii) the consent
of Lind to NioCorp’s expected cross-listing to the Nasdaq and the consolidation of the Common Shares in order to meet the minimum listing requirements thereof; (iii)
the waiver of Lind of its participation right for up to 15% of the total offering in the Yorkville Equity Facility Financing; and (iv) the waiver of Lind of certain restrictive
covenants in the Lind III Agreement.

As consideration for entering into the Lind Consent, Lind received, amongst other things: (i) the right to receive a payment of $500, which would have been reduced to
$200 if the Transactions had not been consummated on or before April 30, 2023 (collectively, the “Consent Payment”); (ii) an extension of its existing participation
rights  under  the  Lind  III  Agreement  in  future  financings  of  NioCorp  for  a  further  two-year  period,  subject  to  certain  exceptions  as  well  as  an  extension  of  such
participation rights beyond the additional two-year period if Yorkville or any affiliate is a party to any such applicable transaction; and (iii) the right to receive additional
Warrants (the “Contingent Consent Warrants”) if on the date that is 18 months following the Closing Date, the closing trading price of the Common Shares on the TSX
or such other stock exchange on which such shares may then be listed, is less than C$10.00 (on a post-Reverse Stock Split basis), subject to adjustments. The number of
Contingent Consent Warrants to be issued, if any, is based on the Canadian dollar equivalent (based on the then current Canadian to US dollar exchange rate as reported
by Bloomberg, LP) of $5,000 divided by the five-day volume weighted average price of the Common Shares on the date of issuance. Further, the number of Contingent
Consent Warrants issued will be proportionately adjusted based on the percentage of Warrants currently held by Lind that are exercised, if any, prior to the issuance of
any Contingent Consent Warrants. The Lind Consent was signed as an amendment to the existing Lind III Agreement.

Management determined that the Lind Consent should be evaluated using ASC 470, which requires an evaluation of the contract amendment under debt modification
guidance. The Company performed a comparison of the discounted cash flows of the Lind III Convertible Security pursuant to the existing Lind III Agreement and
pursuant to the Lind III Agreement as amended by the Lind Consent and determined that a debt extinguishment loss of $201 had occurred. Further, ASC 470 requires
that the minimum estimated Consent Payment of $200 also be included in the calculation of the initial loss on debt extinguishment. The Company also evaluated the
Contingent  Consent Warrant  feature  included  in  the  Lind  Consent  and  determined  that  the  Contingent  Consent Warrants  meet  the  criteria  to  be  considered  separate,
freestanding instruments, should be accounted for as a liability under ASC 480, and should be booked at fair value on the date of the Lind Consent, with subsequent
changes in valuation recorded as a non-operating gain or loss in the consolidated statement of operations and comprehensive loss. The following table summarizes the

The Contingent Consent Warrants are classified as a Level 3 financial instrument and were valued utilizing a Monte Carlo simulation pricing model, which calculates
multiple potential outcomes for future share prices based on historic volatility of the Common Shares to determine the probability of issuance at 18 months following
the applicable valuation date and to determine the value of the Contingent Consent Warrants. The following table discloses the primary inputs into the Monte Carlo
model at each valuation date, and the probability of issuance calculated by the model.

Loss on debt extinguishment is presented as a non-operating expense in the Company’s consolidated statements of operations and comprehensive loss. This accounting
also resulted in a decrease in the amount of accretion to be recognized over the remaining life of the Lind III Convertible Security through February 2023. Accretion
expenses are disclosed as a part of interest expense, which is not included as a component of operating costs.

Yorkville Convertible Debentures

In  connection  with  the  GXII  Transaction,  on  January  26,  2023,  NioCorp  entered  into  definitive  agreements  with  respect  to  the  Yorkville  Financings,  including  a
Securities Purchase Agreement, dated January 26, 2023 (as amended the “Yorkville Convertible Debt Financing Agreement”), between the Company and Yorkville, and
a Standby Equity Purchase Agreement, dated January 26, 2023 (the “Yorkville Equity Facility Financing Agreement”), between the Company and Yorkville.

Pursuant  to  the Yorkville  Convertible  Debt  Financing Agreement,  at  the  Closing, Yorkville  advanced  a  total  amount  of  $15,360  to  NioCorp  in  consideration  of  the
issuance by NioCorp to Yorkville of (i) $16,000 aggregate principal amount of unsecured convertible debentures (the “Convertible Debentures”) and (ii) Common Share
purchase  warrants,  exercisable  for  up  to  1,789,267  Common  Shares  for  cash  or,  if  at  any  time  there  is  no  effective  registration  statement  registering,  or  no  current
prospectus available for, the resale of the underlying Common Shares, on a cashless basis, at the option of the holder, at a price per Common Share of approximately
$8.9422, subject to adjustment to give effect to any stock dividend, stock split, reverse stock split or similar transaction (the “Financing Warrants”).

Each Convertible Debenture issued under the Yorkville Convertible Debt Financing Agreement is an unsecured obligation of NioCorp, has an 18-month term from the
Closing Date, which may be extended for one six-month period in certain circumstances at the option of NioCorp, and incurs a simple interest rate obligation of 5.0%
per annum (which will increase to 15.0% per annum upon the occurrence of an event of default). The outstanding principal amount of, accrued and unpaid interest, if
any,  on,  and  premium,  if  any,  on  the  Convertible  Debentures  must  be  paid  by  NioCorp  in  cash  when  the  same  becomes  due  and  payable  under  the  terms  of  the
Convertible Debentures at their stated maturity, upon their redemption or otherwise.

Subject to certain limitations contained within the Yorkville Convertible Debt Financing Agreement and the Convertible Debentures, including those as described below,
holders of the Convertible Debentures will be entitled to convert the principal amount of, and accrued and unpaid interest, if any, on each Convertible Debenture, in
whole or in part, from time to time over their term, into a number of Common Shares equal to the quotient of the principal amount and accrued and unpaid interest, if
any, being converted divided by the Conversion Price. The “Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, the
greater of (i) 90% of the average of the daily U.S. dollar volume-weighted average price of the Common Shares on the principal U.S. market for the Common Shares as
reported by Bloomberg Financial Markets during the five consecutive trading days immediately preceding the date on which the holder exercises its conversion right in
accordance with the requirements of the Yorkville Convertible Debt Financing Agreement (the “Conversion Date”) or other date of determination, but not lower than the
Floor Price (as defined below), and (ii) the five-day volume-weighted average price of the Common

TSX. The “Floor Price” means a price of $2.1435 per share, which is equal to the lesser of (a) 30% of the average of the daily volume-weighted average price of the
Common  Shares  on  the  principal  U.S.  market  for  the  Common  Shares  as  reported  by  Bloomberg  Financial  Markets  during  the  five  consecutive  trading  days
immediately preceding the Debenture Closing and (b) 30% of the average of the volume-weighted average price of the Common Shares on the principal U.S. market for
the Common Shares as reported by Bloomberg Financial Markets during the five consecutive trading days immediately following the Debenture Closing, subject to
certain adjustments to give effect to any stock dividend, stock split, reverse stock split, recapitalization or similar event.

The terms of the Convertible Debentures restrict the number of Convertible Debentures that may be converted during each calendar month by Yorkville at a Conversion
Price below a fixed price equal to approximately $8.9422 (i.e., the quotient of $10.00 divided by 1.11829212 (being the number of Common Shares that were exchanged
for each share of GXII at the Closing, after giving effect to the Reverse Stock Split)), subject to adjustment to give effect to any stock dividend, stock split, reverse stock
split, recapitalization or similar event. The Convertible Debentures are subject to customary anti-dilution adjustments.

The terms of the Convertible Debentures restrict the conversion of Convertible Debentures by Yorkville if such a conversion would cause Yorkville to exceed certain
beneficial ownership thresholds in NioCorp or such a conversion would cause the aggregate number of Common Shares issued pursuant to the Yorkville Convertible
Debt  Financing Agreement  to  exceed  the  thresholds  for  issuance  of  Common  Shares  under  the  rules  of  the  TSX  and  Nasdaq,  unless  prior  shareholder  approval  is
obtained.

Pursuant to the terms of the Convertible Debentures, following certain trigger events, and until a subsequent cure event, NioCorp will be required to redeem $1,125
aggregate principal amount of Convertible Debentures (the “Triggered Principal Amount”) each month by making cash payments to the Investors, on a pro rata basis, in
an  amount  equal  to  the Triggered  Principal Amount,  plus  accrued  and  unpaid  interest  thereon,  if  any,  plus  a  redemption  premium  of  7%  of  the Triggered  Principal
Amount. Such monthly prepayments under the terms of the Convertible Debentures are triggered (i) at the time when NioCorp has issued 95% of the total amount of
Common Shares pursuant to the Yorkville Convertible Debt Financing that it may issue under applicable TSX and Nasdaq rules or (ii) when NioCorp has delayed or
suspended the effectiveness or use of the Convertible Debt Financing Registration Statement for more than 20 consecutive calendar days, and such monthly prepayment
obligations will continue until, with respect to (i) above, shareholder approval is obtained or, with respect to (ii) above, the Investors may once again resell Common
Shares under the Convertible Debt Financing Registration Statement, respectively.

The Convertible Debentures may also be redeemed at NioCorp’s option at any time and from time to time over their term at a redemption price equal to 110% of the
principal amount being redeemed, plus accrued and unpaid interest, if any.

In  conjunction  with  the  issuance  of  the  Convertible  Debentures,  NioCorp  issued  to  Yorkville  1,789,267  Financing  Warrants  at  an  exercise  price  of  approximately
$8.9422  per  Common  Share  (the  “Financing  Warrant  Exercise  Price”),  subject  to  adjustment  to  give  effect  to  any  stock  dividend,  stock  split,  reverse  stock  split
recapitalization or similar event.

The Financing Warrants are exercisable, in whole or in part, but not in increments of less than $50 aggregate Financing Warrant Exercise Price (unless the remaining
aggregate Financing Warrant Exercise Price is less than $50), beginning on May 4, 2023, and may be exercised at any time prior to their expiration. Holders of the
Financing  Warrants  may  exercise  their  Financing  Warrants,  at  their  election,  by  paying  the  Financing  Warrant  Exercise  Price  in  cash  or,  if  at  any  time  there  is  no
effective registration statement registering, or no current prospectus available for, the resale of the underlying Common Shares, on a cashless exercise basis. 1/12th of
the Financing Warrants will expire on each of the first 12 monthly anniversaries of the date that is six months following the Closing Date.

The Financing Warrants have customary anti-dilution adjustments to be determined in accordance with the requirements of the applicable stock exchanges, including the
TSX. The terms of the Financing Warrants restrict the

exercise of Financing Warrants by Yorkville if such an exercise would cause Yorkville to exceed certain beneficial ownership thresholds in NioCorp or such an exercise
would cause the aggregate number of Common Shares issued pursuant to the Yorkville Convertible Debt Financing Agreement to exceed the thresholds for issuance of
Common Shares under the rules of the Nasdaq and the TSX, unless prior shareholder approval is obtained.

The  Financing Warrants  were  originally  recorded  as  a  $2,704  contingent  liability  on  January  26,  2023,  and  were  subsequently  marked  to  market  of  $3,337  through
March 16, 2023. The change in fair value during this period resulted in a loss of $633, which was booked to change in fair value of warrant liability in the consolidated
statement of operations and comprehensive loss. The Financing Warrants were reclassified to shareholders equity on March 17, 2023, in connection with the closing of
the Convertible Debentures as noted below.

The Company allocated the net proceeds of $15,360 from the Convertible Debentures as follows:

● $2,704  was  booked  to  Common  Shares,  representing  the  initial  fair  value  of  the  Financing Warrant  tranches  on  January  26,  2023  based  on  the  Black  Scholes
pricing model using a risk-free interest rate of 4.33%, an expected dividend yield of 0%, a volatility of 64.6%, and an expected life of 6 months to 18 months.

● $12,656 was booked to the convertible debt liability. In addition, transaction costs of $503 were recognized as a direct deduction from the debt liability, resulting
in a net opening balance of $12,153 at an effective interest rate of 18.4%. This balance will be accreted to face value of the Convertible Debentures at maturity
using the effective interest method and recorded as non-cash interest expense in the consolidated statement of operations and comprehensive loss.

Changes in the Convertible Debentures are as follows:

Opening balance, March 17, 2023
Accretion expense
Principal and accrued interest converted
Balance, June 30, 2023
Add: Unamortized debt issuance costs

1,962

2,439 
13,000 

   $

  $

  $

Upon conversion, the portion of remaining unamortized issuance costs associated with the conversion are recognized as a component of interest expense.

The Convertible Debentures contain events of default customary for instruments of their type (with customary grace periods, as applicable) and provide that, upon the
occurrence of an event of default arising from certain events of bankruptcy or insolvency with respect to NioCorp, all outstanding Convertible Debentures will become
due  and  payable  immediately  without  further  action  or  notice.  If  any  other  type  of  event  of  default  occurs  and  is  continuing,  then  any  holder  may  declare  all  of  its
Convertible Debentures to be due and payable immediately. The Company obtained a waiver from Yorkville with respect to any acceleration rights it may have under
the  Convertible  Debentures  in  connection  with  the  restatements  of  the  Company’s  consolidated  financial  statements  for  the  periods  ended  September  30,  2022  and
December 31, 2022 and the delay in filing the Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2023. The Yorkville Convertible
Debt Financing Agreement also contains certain covenants that, among other things, limit NioCorp’s ability to use the proceeds from the Yorkville Convertible Debt
Financing to repay related party debt or to enter into any variable rate transaction other than with Yorkville, subject to certain exceptions.

Based on the Company’s closing Common Share price of $5.03 as of June 30, 2023, conversion of the remaining Convertible Debenture principal balance of $13.0
million, including accrued interest, would require the issuance of approximately 2,871,660 Common Shares. For each $0.10 change in the fair value of one Common
Share, the total shares the Company would be obligated to issue would change by approximately 58,300 shares.

10. CLASS B COMMON STOCK OF ECRC

Pursuant to the Business Combination Agreement, the Sponsor Support Agreement, and the Exchange Agreement, after the Closing, the GXII founders have the right to
exchange shares of Class B common stock of ECRC for Common Shares on a one-for-one basis, subject to certain equitable adjustments, under certain conditions. All
7,957,404 shares of Class B common stock of ECRC that were issued in connection with the Closing were issued and outstanding as of June 30, 2023. Of the issued and
outstanding shares of Class B common stock of ECRC, 4,565,808 shares (the “Vested Shares”) were vested as of the Closing Date and are exchangeable at any time, and
from time to time, until the tenth anniversary of the Closing Date (the “Ten-Year Anniversary”) and 3,391,596 shares (the “Earnout Shares”) are exchangeable until the
Ten-Year Anniversary, subject to certain vesting conditions. Under certain circumstances, and subject to certain exceptions, NioCorp may instead settle all or a portion
of any exchange pursuant to the terms of the Exchange Agreement in cash, in lieu of Common Shares, based on a volume-weighted average price of Common Shares.

All  of  the  shares  of  Class  B  common  stock  of  ECRC  are  subject  to  the Amended  and  Restated  Registration  Rights Agreement,  dated  as  of  March  17,  2023  (the
“Registration Rights and Lock-up Agreement”), among NioCorp, GXII, the Sponsor, the pre-Closing directors and officers of NioCorp and the other parties thereto,
including the members of the Sponsor. Pursuant to Registration Rights and Lock-up Agreement, all shares of Class B common Stock of ECRC (including the Vested
Shares and the Released Earnout Shares) are subject to certain “lock-up” restrictions on transfer beginning upon the Closing and ending upon the earlier of (i) one year
after the Closing and (ii) the date on which the trading price of Common Shares exceeds certain thresholds or the date on which NioCorp completes a transaction that
results  in  all  of  NioCorp’s  shareholders  having  the  right  to  exchange  their  Common  Shares  for  cash,  securities  or  other  property.  Both Vested  Shares  and  Released
Earnout Shares may be exchanged by the holders into Common Shares at any time. Under the Exchange Agreement, all Vested Shares and Earnout Shares must be
exchanged for Common Shares by the Ten-Year Anniversary except for Released Earnout Shares that have been vested for a period of fewer than twenty-four months as
of  the Ten-Year Anniversary.  Such  Released  Earnout  Shares  will  be  forfeited  if  not  exchanged  for  Common  Shares  by  the  date  that  is  twenty-four  months  after  the
vesting date.

Vested Shares

As the exchange of Vested Shares are contingently redeemable at the option of the noncontrolling interest shareholders, the Company classifies the carrying amount of
the redeemable noncontrolling interest in the mezzanine section on the consolidated balance sheet, which is presented above the equity section and below liabilities. The
redeemable  noncontrolling  interests  are  classified  as  a  Level  1  financial  instrument  and  are  measured  at  the  fair  value  of  the  Company’s  Common  Shares  at  each
reporting period. Adjustments to the carrying value of the redeemable noncontrolling interest are recorded through retained earnings.

Earnout Shares

The  Earnout  Shares  vest  (the  “Released  Earnout  Shares”)  in  two  equal  tranches  based  upon  achieving  market  share  price  milestones  of  approximately  $12.00  per
Common Share and approximately $15.00 per Common Share, respectively, prior to the Ten-Year Anniversary, or upon a change in control as defined in the underlying
agreement. These shares will be forfeited if the market share price milestones or an acceleration event is not reached prior to the Ten-Year Anniversary. At such time that
the Earnout Shares shall become vested, and therefore, become Released Earnout Shares, the shares will be transferred to the redeemable noncontrolling interest in the
mezzanine section of the Consolidated Balance Sheet.

The Earnout Shares were classified as a liability due to failure to meet the equity classification criteria under ASC 815-40, as Level 3 instruments under the fair value
hierarchy and are considered a financial liability under ASC 480, Distinguishing Liabilities from Equity. The Earnout Shares were measured at fair value on the Closing
Date with subsequent changes in fair value recorded in earnings. The Earnout Shares were valued utilizing a Monte Carlo simulation pricing model, which calculates
multiple potential outcomes for future share prices and establishes current fair value based on the most likely outcome. The following table discloses the primary inputs
into the Monte Carlo models.

11. COMMON SHARES

a)

Issuances

Fiscal Year 2023 Issuances

In addition to the Common Shares issued in connection with the GXII Transaction, as discussed in Note 5, the following Common Share issuances occurred during
fiscal year 2023:

On April 28, 2023, the Company closed a registered direct offering and issued 314,465 Common Shares for $2.0 million, before deducting share issuance costs of
$172. The Common Shares were sold pursuant to a securities purchase agreement, dated April 26, 2023, between the Company and a fund managed by Kingdon
Capital Management, LLC.

On June 9, 2023, the Company issued 100,000 Common Shares under the Yorkville Equity Facility Financing Agreement (discussed below) in exchange for $488
in cash proceeds. The Company recorded a non-cash operating expense of $13 which represented the difference between the proceeds received and the fair value of
the Common Shares issued based on Nasdaq closing price per Common Share on the issuance date.

Fiscal Year 2022 Issuances

On June 30, 2022, the Company closed a non-brokered private placement (the “June 2022 Private Placement”) of units (the “Units”) of the Company. A total of
498,103  Units  were  issued  at  a  price  per  Unit  of  C$0.96,  for  total  gross  proceeds  to  the  Company  of  approximately  C$4.8  million.  Each  Unit  consists  of  one
Common Share and one common share purchase warrant (“June 2022 Warrant”). Each June 2022 Warrant entitles the holder to acquire one Common Share at a
price of C$1.10 at any time prior to July 1, 2024. Proceeds of the June 2022 Private Placement will be used for continued advancement of the Company’s Elk Creek
Critical Minerals Project and for working capital and general corporate purposes. The Company paid cash commissions of C$62 and 6,510 warrants (the “Finder
Warrants”), having the same terms as the June 2022 Warrants, to finders outside of the United States. The Finder Warrants were valued at C$18 using a risk-free
rate of 3.2%, expected volatility of 64% and expected life of two years.

b) Stock Options

On November 5, 2020, the Company’s shareholders voted to approve an amendment and restatement of its long-term incentive plan (the “2017 Amended Long-
Term Incentive Plan”) and the granting of incentive securities thereunder until November 5, 2023. Under the 2017 Amended Long-Term Incentive Plan, the Board
may, in its discretion from time to time, grant Options and share units (in the form of restricted share units and performance

share units) to directors, employees and certain other service providers (as defined in the 2017 Amended Long-Term Incentive Plan) of the Company and affiliated
entities selected by the Board.

Subject to adjustment as described in the 2017 Amended Long-Term Incentive Plan, the aggregate number of Common Shares that may be reserved for issuance to
participants  under  the  2017 Amended  Long-Term  Incentive  Plan,  together  with  all  other  security-based  compensation  arrangements  of  the  Company,  may  not
exceed 10% of the issued and outstanding Common Shares from time to time, and the Common Shares reserved for issuance upon settlement of share units will not
exceed  5%  of  the  issued  and  outstanding  Common  Shares  from  time  to  time.  The  2017 Amended  Long-Term  Incentive  Plan  limits  the  maximum  number  of
Common Shares issued to insiders (as defined under TSX rules for this purpose) within any one-year period, or issuable to insiders at any time, in the aggregate,
under all security-based compensation arrangements (including the 2017 Amended Long-Term Incentive Plan) to 10% of the then issued and outstanding Common
Shares. The 2017 Amended Long-Term Incentive Plan also limits the aggregate number of Common Shares that may be reserved for issuance to any one participant
under the 2017 Amended Long-Term Incentive Plan, together with all other security-based compensation arrangements of the Company, to 5% of the then issued
and  outstanding  Common  Shares  (on  a  non-diluted  basis).  Subject  to  the  adjustment  provisions  of  the  2017 Amended  Long-Term  Incentive  Plan,  the  aggregate
number of Common Shares actually issued or transferred by the Company upon the exercise of Incentive Stock Options will be limited as described above.

The Board has power over the granting, amendment, administration, or settlement of any award.

Notes to Consolidated Financial Statements
June 30, 2023
(expressed in thousands of U.S. dollars, except share and per share data)

In connection with the Closing, pursuant to the Business Combination Agreement, the Company assumed the GXII Warrant Agreement and each GXII Warrant
thereunder that was issued and outstanding immediately prior to the Closing Date was converted into one NioCorp Assumed Warrant pursuant to the GXII Warrant
Agreement, as amended by an Assignment, Assumption and Amendment Agreement, dated March 17, 2023, among the Company, GXII, Continental Stock Transfer
& Trust Company, as the existing warrant agent, and Computershare Inc. and its affiliate, Computershare Trust Company, N.A, together as the successor warrant
agent (the “NioCorp Assumed Warrant Agreement”). In connection with the Closing, NioCorp issued (a) 9,999,959 public NioCorp Assumed Warrants (the “Public
Warrants”) in respect of the GXII Warrants that were publicly traded prior to the Closing and (b) 5,666,667 NioCorp Assumed Warrants (the “Private Warrants”) to
the Sponsor in respect of the GXII Warrants that it held prior to the Closing, which NioCorp Assumed Warrants were subsequently distributed by the Sponsor to its
members in connection with the Closing.

Each NioCorp Assumed Warrant entitles the holder to the right to purchase 1.11829212 Common Shares at an exercise price of $11.50 per 1.11829212 Common
Shares (subject to adjustments for stock splits, stock dividends, reorganizations, recapitalizations and the like). No fractional shares will be issued upon exercise of
any NioCorp Assumed Warrants, and fractional shares that would otherwise be due to the exercising holder will be rounded down to the nearest whole Common
Share. In no event will the Company be required to net cash settle any NioCorp Assumed Warrant.

Public Warrants

The Company may elect to redeem the Public Warrants subject to certain conditions, in whole and not in part, at a price of $0.01 per Public Warrant if (i) 30 days’
prior written notice of redemption is provided to the holders, (ii) the last reported sale price of the Common Shares equals or exceeds approximately $16.10 per
share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on
the  third  business  day  prior  to  the  date  on  which  the  Company  sends  the  notice  of  redemption  to  the  warrant  holders  and  (iii)  there  is  an  effective  registration
statement covering the Common Shares issuable upon exercise of the Public Warrants, and a current prospectus relating thereto, available through the redemption
date. Upon issuance of a redemption notice by the Company, the warrant holders will have until the redemption date to exercise for cash, or, at the Company’s
election,  on  a  cashless  basis. The  Public Warrants  are  not  precluded  from  equity  classification  and  are  accounted  for  as  such  on  the  date  of  issuance,  and  each
balance sheet date thereafter. Because the Transactions resulted in an excess of liabilities over assets acquired, no value was ascribed to the Public Warrants.

Private Warrants

The Private Warrants: (i) will be exercisable either for cash or on a cashless basis at the holder’s option and (ii) will not be redeemable by the Company, in either
case as long as the Private Warrants are held by the Sponsor, its members or any of their permitted transferees (as prescribed in the NioCorp Assumed Warrant
Agreement). In accordance with the NioCorp Assumed Warrant Agreement, any Private Warrants that are held by someone other than the Sponsor, its members or
any their permitted transferees are treated as Public Warrants.

The Company accounts for the Private Warrants assumed in the Transactions in accordance with the guidance contained in ASC 815-40. Such guidance provides
that  because  the  Private Warrants  do  not  meet  the  criteria  for  equity  treatment  thereunder,  each  Private Warrant  must  be  recorded  as  a  liability. This  liability  is
carried as a component of Warrant Liabilities on the consolidated balance sheet and is subject to re-measurement at each balance sheet date. With each such re-
measurement, the warrant liability will be adjusted to its current fair value, with the change in fair value recognized in the consolidated statement of operations and
comprehensive loss. The Company will reassess the classification at each balance sheet date.

The Company classifies Private Warrants as Level 2 instruments under the fair value hierarchy and estimated the fair value using a Black Scholes model with the
following assumptions:

d) Yorkville Equity Facility Financing

Concurrent with the closing of the GXII Transaction, the Yorkville Equity Facility Financing became effective. Pursuant to the Yorkville Equity Facility Financing
Agreement, Yorkville committed to purchase up to $65,000 of Common Shares (the “Commitment Amount”), at NioCorp’s direction from time to time for a period
commencing upon the Closing Date and ending on the earliest of (i) the first day of the month next following the 36-month anniversary of the Closing, (ii) the date
on which Yorkville shall have made payment of the full Commitment Amount and (iii) the date that the Yorkville Equity Facility Financing Agreement otherwise
terminates  in  accordance  with  its  terms  (the  “Commitment  Period”),  subject  to  certain  limitations  and  the  satisfaction  of  the  conditions  in  the Yorkville  Equity
Facility  Financing  Agreement.  The  Common  Shares  that  may  be  sold  pursuant  to  the  Yorkville  Equity  Facility  Financing  Agreement  would  be  purchased  by
Yorkville at a purchase price equal to 97% of the daily volume-weighted average price of the Common Shares on Nasdaq or such other principal U.S. market for
the Common Shares if the Common Shares are ever listed or traded on the New York Stock Exchange or the NYSE American as reported by Bloomberg Financial
Markets  (or,  if  not  available,  a  similar  service  provider  of  national  recognized  standing)  during  the  applicable  pricing  period,  which  is  a  period  during  a  single
trading  day  or  a  period  of  three  consecutive  trading  days,  at  the  Company’s  option  and  subject  to  certain  restrictions,  in  each  case,  defined  based  on  when  an
Advance Notice (as defined in the Yorkville Equity Facility Financing Agreement) is submitted, subject to certain limitations.

Pursuant to the terms of the Yorkville Equity Facility Financing Agreement, NioCorp issued 81,213 of Common Shares (the “Commitment Shares”) valued at $650
to Yorkville  as  consideration  for  its  irrevocable  commitment  to  purchase  Common  Shares  under  the Yorkville  Equity  Facility  Financing Agreement.  On  June  9,
2023, NioCorp issued and sold 100,000 Common Shares to Yorkville under the Yorkville Equity Facility Financing Agreement. Additionally, NioCorp is required to
pay Yorkville an aggregate fee of $1,500 in cash (the “Cash Fee”), including $500 that NioCorp paid on the Closing Date and an additional $250 NioCorp was paid
as of June 30, 2023. NioCorp will pay the remaining $750 balance in installments over a 12-month period following the Closing Date, provided that it will have the
right to prepay without penalty all or part of the remaining installments of the Cash Fee at any time. In addition, legal and other costs of $496 were incurred in
connection with the Yorkville Equity Facility Financing and were expensed on the effective date. The following amounts related to the Yorkville Equity Facility
Financing Agreement were expensed as other operating costs:

Yorkville Cash Fee
Fair value of Commitment Shares issued
Legal and other related costs
Net costs expensed to other operating expense

12. RELATED PARTY TRANSACTIONS AND BALANCES

Borrowings  under  the  non-revolving  credit  facility  agreement  (the  “Smith  Credit  Facility”)  with  Mark  Smith,  Chief  Executive  Officer,  President,  and  Executive
Chairman of NioCorp, bear interest at a rate of 10% and drawdowns from the Smith Credit Facility are subject to a 2.5% establishment fee. Amounts outstanding under
the Smith Credit Facility are secured by all of the Company’s assets pursuant to a general security agreement. The Smith Credit Facility contains financial and non-
financial covenants customary for a facility of its size and nature. The maturity date for the Smith Credit Facility was June 30, 2023. On February 28, 2023, the Smith
Credit facility was amended to increase the borrowing limit to $4,000 from the previous limit of $3,500. The Company subsequently drew down $1,130, leaving an
available balance under the Smith Credit Facility of $52.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes. The significant components of deferred taxes are as follows:

During the year ended June 30, 2022, we identified errors in the recognition of capital losses related to realized mineral property write downs and foreign exchange
gains and losses in Canada which resulted in changes to capital losses available for future periods and other of $(221) and $(3), respectively. These changes primarily
related to adjustments to deferred tax assets recorded during fiscal year 2021. In addition, during the year ended June 30, 2022, we identified an error in the recognition
of net operating losses related to disallowed interest expense for the prior year which resulted in a decrease to net operating loss carryforwards of $19. After evaluation
and consideration of the full valuation allowance historically applied against total deferred tax assets, we determined that the impact of the adjustments was not material
to the previously issued consolidated financial statements, nor are the out of period adjustments material to the estimated results for the year ended June 30, 2022.

Changes in the valuation allowance are as follows:

NioCorp Developments Ltd.
Notes to Consolidated Financial Statements
June 30, 2023
(expressed in thousands of U.S. dollars, except share and per share data)

The Company acquired a federal income tax payable of $406 in connection with the GXII Transaction. As a result of a post-transaction loss at ECRC, a partial release of
the valuation allowance attributed to the reduction of the acquired federal income tax payable of $304 has been recorded as an income tax benefit in the consolidated
statement of operations and comprehensive loss for the year ended June 30, 2023. The Company establishes a valuation allowance against future income tax assets if,
based on available information, it is more likely than not that all of the assets will not be realized. The valuation allowance of $25,463 at June 30, 2023, relates mainly
to net operating loss carryforwards in Canada and mineral interests due to deferred exploration expenditures in the United States, where the utilization of such attributes
is not more likely than not.

The Company has the following cumulative net operating losses for Canadian and U.S. income tax purposes and these carryforwards will generally expire between 2026
and  2043.  As  a  result  of  the  Tax  Cuts  and  Jobs  Act  of  2017,  U.S.  tax  losses  incurred  for  tax  years  ending  on  and  after  June  30,  2019,  totaling  $2,510,  have  no
expiration..

In addition, the Company has a Canadian capital loss carryforward of $3,375 as of June 30, 2023, which has no expiration date and can be used to offset future capital
gains, and U.S. state net operating loss carryforwards of $4,943 as of June 30, 2023 which generally expire between 2031 and 2043.

The  Company  had  no  unrecognized  tax  benefits  as  of  June  30,  2023  or  2022.  The  Company  recognizes  interest  accrued  related  to  unrecognized  tax  benefits  and
penalties in its income tax provision. The Company has not recognized any interest or penalties in the fiscal years presented in these consolidated financial statements.
The Company is subject to income tax in the U.S. federal jurisdiction and Canada. Certain years remain subject to examination but there are currently no ongoing exams
in any taxing jurisdictions.

16. FAIR VALUE MEASUREMENTS

The Company measures the fair value of financial assets and liabilities based on U.S. GAAP guidance which defines fair value, establishes a framework for measuring
fair value, and expands disclosures about fair value measurements.

The  Company  classifies  financial  assets  and  liabilities  as  held-for-trading,  available-for-sale,  held-to-maturity,  loans  and  receivables,  or  other  financial  liabilities
depending on their nature. Financial assets and financial liabilities are recognized at fair value on their initial recognition.

Financial assets and liabilities classified as held-for-trading are measured at fair value, with gains and losses recognized in net income. Financial assets classified as
held-to-maturity, loans and receivables, and financial liabilities other than those classified as held-for-trading are measured at amortized cost, using the effective interest
method of amortization. Financial assets classified as available-for-sale, including investments in equity securities, are measured at fair value, with unrealized gains and
losses being recognized in income.

 Financial instruments including receivables, accounts payable and accrued liabilities, and related party loans are carried at amortized cost, which management believes
approximates fair value due to the short-term nature of these instruments.

The following tables present information about the assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2023, and June 30, 2022,
respectively, and indicate the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value. In general, fair values determined by
Level  1  inputs  utilize  quoted  prices  (unadjusted)  in  active  markets  for  identical  instruments.  Fair  values  determined  by  Level  2  inputs  utilize  data  points  that  are
observable, such as quoted prices, interest rates, and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the financial instrument and
include situations where there is little, if any, market activity for the instrument.

The Yorkville Convertible Debt Financing discussed in Note 9 was initially recorded at fair value, which represented a nonrecurring fair value measurement using a
Level 3 input. At June 30, 2023, the estimated fair value of this instrument approximated carrying value given that the instrument was issued in March 2023 and has a
short time period until maturity. 

17. SUBSEQUENT EVENTS

On September 1, 2023, the Company closed a non-brokered private placement (the “September 2023 Private Placement”) of units of the Company (the “September
2023  Units”). A  total  of  250,000  September  2023  Units  were  issued  at  a  price  per  September  2023  Unit  of  $4.00,  for  total  gross  proceeds  to  the  Company  of  $1.0
million.  Each  September  2023  Unit  consists  of  one  Common  Share  and  one  Common  Share  purchase  warrant  (“September  2023  Warrant”).  Each  September  2023
Warrant entitles the holder to acquire one Common Share at a price of $4.60 at any time prior to September 1, 2025. Proceeds of the September 2023 Private Placement
will be used for continued advancement of the Company’s Elk Creek Critical Minerals Project and for working capital and general corporate purposes.

On  September  12  and  September  18,  2023,  the  Company  issued  70,000  and  75,000  Common  Shares,  respectively,  under  the  Yorkville  Equity  Facility  Financing
Agreement in exchange for $0.5 million in gross cash proceeds.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The management of NioCorp Developments Ltd. has evaluated, under the supervision and with the participation of our Chief Executive Officer (“CEO”) and Chief
Financial Officer (“CFO”), the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30,
2023.  Based  on  that  evaluation,  the  CEO  and  the  CFO  have  concluded  that,  as  of  June  30,  2023,  our  disclosure  controls  and  procedures  were  not  effective  due  to  the
material weaknesses in internal control over financial reporting described below.

The Company’s disclosure controls and procedures have been designed to ensure that: (i) information required to be disclosed by us in reports that we file or submit to
the  SEC  under  the  Exchange  Act  is  recorded,  processed,  summarized,  and  reported  within  the  time  periods  specified  in  applicable  rules  and  forms  and  (ii)  material
information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including the CEO and the CFO, as
appropriate, to allow for accurate and timely decisions regarding required disclosures.

Management  does  not  expect  that  our  disclosure  controls  and  procedures  will  prevent  all  error  and  all  fraud.  The  effectiveness  of  our  or  any  system  of  disclosure
controls and procedures, however well designed and operated, can provide only reasonable assurance that the objectives of the system will be met and is subject to certain
limitations, including the exercise of judgment in designing, implementing, and evaluating controls and procedures and the assumptions used in identifying the likelihood of
future events.

Management’s Report on Internal Control over Financial Reporting

The management of NioCorp Developments Ltd. is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Our
management assessed the effectiveness of our internal control over financial reporting as of June 30, 2023. In making this assessment, our management used the criteria set
forth in the Internal Control -Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO Framework”).
Based on that evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this Annual Report, our internal control over financial reporting
was not effective due to the material weaknesses in internal control over financial reporting described below.

Material Weaknesses in Internal Control over Financing Reporting Existing as of June 30, 2023

A  material  weakness  is  a  deficiency,  or  a  combination  of  deficiencies,  in  internal  control  over  financial  reporting,  such  that  there  is  a  reasonable  possibility  that  a

material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Management concluded that the previously disclosed material weakness relating to the Company’s controls over the accounting for non-routine transactions continued
to exist as of June 30, 2023. Specifically, such controls were not adequately designed to ensure the consideration of all related relevant accounting guidance when such
transactions were recorded. As disclosed in the Company’s Amendment No. 1 on Form 10-K/A to its Annual Report on Form 10-K for the fiscal year ended June 30, 2022,
and in the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended September 30, 2022, December 31, 2022 and March 31, 2023, this material weakness
resulted in the restatement of the Company’s consolidated financial statements as of and for the fiscal years ended June 30, 2022 and 2021, as well as the restatement of the
Company’s condensed consolidated financial statements as of and for the interim periods ended September 30, 2021, December 31, 2021, and March 31, 2022.

The Company identified an additional error during the quarter ended March 31, 2023 relating to the accounting treatment of the Lind Consent. The error required the
restatement  of  the  Company’s  condensed  consolidated  financial  statements  as  of  and  for  the  periods  ended  September  30,  2022  and  December  31,  2022. The  Company
determined

94

 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
that the error was partially caused by the same material weakness that existed as of June 30, 2022, September 30, 2022 and December 31, 2022. The material weakness
discussed above continued to exist as of June 30, 2023.

In  addition  to  the  material  weakness  discussed  above,  our  management  concluded  that  three  other  material  weaknesses  in  internal  control  over  financial  reporting

existed as of June 30, 2023. A cumulative listing of our material weaknesses is disclosed below:

● Control  Environment:  Management  did  not  design  and  maintain  an  effective  control  environment  based  on  the  criteria  established  by  the  COSO  Framework.
Specifically, the Company does not have sufficient personnel with the appropriate levels of knowledge, experience, and training in accounting and internal control
over  financial  reporting  commensurate  with  the  complexity  of  the  Company’s  business.  This  material  weakness  contributed  to  additional  material  weaknesses
related to the Company’s control activities as further described below.

● Risk Assessment: Management did not design and maintain effective controls over the risk assessment process. Specifically, management does not have a formal
process to identify, update, and assess risks due to changes in the Company’s business practices, including entering into increasingly complex transactions that
could significantly impact the design and operation of the Company’s control activities.

● Control  Activities:  Management  did  not  design  and  maintain  effective  controls,  including  management  review  controls,  related  to  non-routine  transactions.
Specifically,  management  did  not  maintain  effective  controls  over  monitoring  and  assessing  the  work  of  third-party  specialists,  including  the  evaluation  of  the
appropriateness of accounting conclusions that has resulted in misstatements. In addition, the Company did not design and maintain effective controls related to the
evaluation  of  certain  inputs  and  assumptions  used  to  estimate  the  fair  value  of  instruments  and  features  associated  with  complex  debt  and  equity  transactions.
Finally, management did not have policies and procedures for the reconsideration of existing agreements when infrequent transactions occur.

● Monitoring Activities: Management did not design and maintain effective monitoring controls to support timely evaluation of remediation of identified internal

control deficiencies.

Additionally, these material weaknesses could result in a misstatement of the account balances or disclosures that would result in a material misstatement to the annual

or interim consolidated financial statements that would not be prevented or timely detected.

Remediation Plan for the Material Weakness

To address our material weaknesses existing as of June 30, 2023, we are currently devising a detailed plan to address each individual material weakness identified, as

well as the overall monitoring process, including the following:

● In  order  to  remediate  the  material  weaknesses  relating  to  the  Company’s  control  environment  and  risk  assessment  process,  we  plan  to  develop  and  implement
controls to ensure work performed by Company personnel and other experts is reviewed by individuals with the appropriate level of U.S. GAAP knowledge and
experience. This may include separating the performance and review of certain close procedures among current accounting personnel and/or engaging third party
accounting  consultants  with  the  requisite  U.S.  GAAP  knowledge  and  experience  to  perform  work  under  the  control  and  oversight  of  Company  personnel.  In
addition, we plan to enhance the design of our controls over the consideration of all related relevant accounting guidance for the initial recording and subsequent
measurements of non-routine transactions.

● In order to remediate the material weakness relating to the Company’s controls activities, we are in the process of designing and implementing controls over the
completeness and accuracy of identifying and adequately assessing the assumptions utilized in the valuation analysis of complex financial instruments, as well as
engaging third party consultants with the relevant background and expertise to perform the appropriate complex valuation analyses under the control and oversight
of Company personnel.

● In order to remediate the material weakness relating to the Company’s controls over monitoring activities, we plan to design and implement controls to manage and

monitor our progress towards the remediation of

95

 
  
 
 
 
 
 
 
 
 
 
 
 
 
internal control deficiencies and material weaknesses, including oversight by, and periodic reporting to, the Audit Committee.

The process of designing and maintaining effective internal control over financial reporting is a continuous effort that requires management to anticipate and react to
changes in our business, economic and regulatory environments and to expend significant resources. As we continue to evaluate our internal control over financial reporting,
we may take additional actions to remediate the material weaknesses or modify the remediation actions described above.

While we continue to devote significant time and attention to these remediation efforts, the material weaknesses will not be considered remediated until management
completes the design and implementation of the actions described above and the controls operate for a sufficient period of time, and management has concluded, through
testing, that these controls are effective.

Changes in Internal Control over Financial Reporting

Other than as discussed above, there has been no change in our internal control over financial reporting during the quarter ended June 30, 2023, that has materially

affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

During the quarter ended June 30, 2023, no director or officer (as defined in Rule 16a-1(f) promulgated under the Exchange Act) of the Company adopted or

terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement” (as each term is defined in Item 408 of Regulation S-K).

legal proceedings are believed to be contemplated by governmental authorities against any director or executive officer.

Ethical Business Conduct

The Board expects management to operate the business of the Company in a manner that enhances shareholder value and is consistent with the highest level of integrity.
Management is expected to execute the Company’s business plan and to meet performance goals and objectives according to the highest ethical standards.

In addition, directors and senior officers are bound by the provisions of the Company’s Articles and the British Columbia Business Corporations Act (“BCBCA”), which set
forth how any conflicts of interest are to be dealt with. In particular, any director who has a material interest in a particular transaction is required to disclose such interest
and to refrain from voting with respect to the approval of any such transaction.

Code of Business Conduct and Ethics

Our Board has adopted a written Code of Business Conduct and Ethics applicable to our employees, officers, and directors, including those officers responsible for financial
reporting. The Code of Business Conduct and Ethics is available on our website at www.niocorp.com. If the Board amends the Code of Business Conduct and Ethics or
grants a waiver, including an implicit waiver, from the Code of Business Conduct and Ethics, the Company will disclose the information on its internet website. The waiver
information will remain on the website for at least 12 months after the initial disclosure of such waiver. Given the current size of the Company workforce, and the lack of
significant operations, the Board monitors compliance through periodic discussions with executive management.

Audit Committee and Audit Committee Financial Experts

Our Audit Committee is currently comprised of Anna Castner Wightman, Michael J. Morris, and Nilsa Guerrero-Mahon, all of whom are independent directors. Our Board
has determined that Mr. Morris and Ms. Guerrero-Mahon are audit committee financial experts, as defined by the rules of the SEC. Further, all Audit Committee members
are financially literate as defined in NI 52-110. The Audit Committee was established in accordance with Section 3(a)(58)(A) of the Exchange Act.

Narrative Disclosure to Summary Compensation Table

Compensation Governance

The Company’s Compensation Committee determines an appropriate amount of compensation for the Company’s executives, reflecting the need to provide incentives and
compensation for the time and effort expended by the executives while taking into account the financial and other resources of the Company. The Compensation Committee
has  the  authority  to  engage  and  compensate,  at  the  expense  of  the  Company,  any  outside  advisor  that  it  determines  to  be  necessary  to  permit  it  to  carry  out  its  duties
(including compensation consultants and advisers), and utilized information provided by Insperity PEO Services LP (“Insperity”), the Company’s Professional Employer
Organization, in February 2023, to assess employee salaries relative to industry and market peers.

Compensation Program Design

The  Board,  in  conjunction  with  the  Compensation  Committee,  determines  compensation  and  rewards  to  senior  management  on  the  basis  of  individual  and  corporate
performance, both in the short term and the long term, while at the same time being mindful of the responsibility that the Company has to its shareholders. In general, the
Compensation Committee considers that its compensation program should be relatively simple in concept, given the current stage of the Company’s development, and that
its focus should be balanced between reasonable current compensation and longer-term compensation tied to performance of the Company as a whole.

The Compensation Committee has not established a formal set of benchmarks or performance criteria to be met by the Company’s named executive officers; rather, the
members  of  the  Compensation  Committee  use  the  information  provided  by  Insperity  and  their  own  subjective  assessments  of  the  level  of  success  of  the  Company  to
determine, collectively, whether or not the named executive officers are successfully achieving the Company’s business plan and strategy and the degree to which they have
performed in that regard. The Compensation Committee has not established any set or formal formula for determining named executive officer compensation, either as to the
amount  thereof  or  the  specific  mix  of  compensation  elements,  and  compensation  (and  adjustments  from  time  to  time)  is  set  through  informal  discussions  at  the
Compensation Committee level.

Key Elements of Named Executive Officer Compensation

Base Salaries

The members of the Compensation Committee use their own experience and familiarity with the industry, and consider the factors described above, to determine what they
believe  to  be  reasonable  base  salaries  for  our  named  executive  officers.  The  base  salaries  of  the  named  executive  officers  are  set  at  levels  which  are  considered  by  the
members of the Compensation Committee to be competitive, thereby enabling the Company to compete for and retain executives critical to the long-term success of the
Company. Initially, base salaries (or, for Mr. Smith, base consulting fees) are set through negotiation when executive officers join the Company (with direct input from the
Compensation Committee) and are subsequently reviewed each fiscal year to determine if adjustments are required.

Effective April 1, 2023, the Compensation Committee approved the following increases to the named executive officers’ base salaries to reflect each executive’s experience,
contribution, responsibilities and pay relative to market and among senior executives at the Company.

The  Board  has  discretion,  where  deemed  appropriate  and  financially  affordable  for  the  Company,  to  grant  a  cash  bonus  to  a  named  executive  officer  based  on  the
performance of both the individual named executive officer and the Company. In March 2023, the Compensation Committee approved the following discretionary bonuses
for the named executive officers, each of which was paid in April 2023:

These one-time bonuses were intended to reflect the Compensation Committee’s desire to reward individual performance and teamwork across the senior leadership level.

Option-Based Awards

The incentive portion of each named executive officer’s compensation package consists primarily of Options awarded under the 2017 Amended Long-Term Incentive Plan.
Share ownership opportunities through the grant of Options are provided to align the interests of senior management of the Company with the longer-term interests of the
shareholders of the Company.

The  2017 Amended  Long-Term  Incentive  Plan  is  administered  by  the  Compensation  Committee,  and  is  intended  to  advance  the  interests  of  the  Company  through  the
motivation,  attraction  and  retention  of  officers  and  other  key  employees,  directors  and  consultants  of  the  Company  and  affiliates  of  the  Company  and  to  secure  for  the
Company and its shareholders the benefits inherent in the ownership of Common Shares of the Company by officers and other key employees, directors and consultants of
the Company and affiliates of the Company. Grants of Options under the 2017 Amended Long-Term Incentive Plan are proposed/recommended by the CEO, and reviewed
by  the  Compensation  Committee.  The  Compensation  Committee  can  approve,  modify,  or  reject  any  proposed  grants,  in  whole  or  in  part.  In  general,  the  allocation  of
available Options among the eligible participants in the 2017 Amended Long-Term Incentive Plan is on an ad hoc basis, and there is no set formula for allocating available
Options, nor is there any fixed benchmark or performance criteria to be achieved in order to receive an award of or vest in Options.

The Compensation Committee does not consider the accounting value of any such Option grants in determining the number of Options to award to any individual, as any
such  “value”  is  an  accounting  measure  that  is  not  relevant  to  incentivizing  the  individual.  The  timing  of  the  grants  of  Options  is  determined  by  the  Compensation
Committee, and there is no regular interval for the awarding of Option grants. In general, a higher level of responsibility will result in a larger grant of Options. Because the
number  of  Options  available  is  limited,  in  general,  the  Compensation  Committee  aims  to  have  individuals  at  what  it  subjectively  considers  to  be  the  same  levels  of
responsibility holding equivalent numbers of Options, with additional grants being allocated for individuals who the Compensation Committee believes are in a position to
more directly affect the success of the Company through their efforts.

The Compensation Committee looks at the overall number of Options held by an individual (plus the exercise prices and remaining terms of existing Options and whether
any previously granted Options have expired out of the money or were exercised) and takes such information into consideration when reviewing proposed new grants. After
considering the CEO’s recommendations and the foregoing factors, the resulting proposed Option grant (if any) is then submitted to the Board for approval.

During the fiscal year ended June 30, 2023, the Compensation Committee approved all recommendations for the grant of Options proposed by management, and the named
executive officers were granted the following number of Options effective March 27, 2023, each with an exercise price per share of $6.95 per share: Mr. Smith, 70,000
Options; Mr. Honan, 40,000 Options; and Mr. Shah, 40,000 Options. These Options were fully vested on the grant date and generally remain exercisable until three years
after the grant date.

Employment Agreements and Severance Arrangements

The Company and KMSmith, LLC (“KMSmith”), an entity controlled by Mark A. Smith, entered into a Consulting Agreement effective September 23, 2013 (as amended,
the “Smith Agreement”). On August 31, 2020, the Company, KMSmith and 76 Resources, Inc., an entity controlled by Mr. Smith, entered into a Contract Assignment and
Novation  Agreement,  pursuant  to  which  KMSmith  assigned  all  of  its  rights  under  the  Smith  Agreement  to  76  Resources,  Inc.  and  76  Resources,  Inc.  assumed  all  of
KMSmith’s obligations under the Smith Agreement by novation. On August 1, 2021, the Company, 76 Resources, Inc. and 76 Resources, LLC, an entity controlled by Mr.
Smith,  entered  into  a  Contract Assignment  and  Novation Agreement,  pursuant  to  which  76  Resources,  Inc.  assigned  all  of  its  rights  under  the  Smith Agreement  to  76
Resources, LLC and 76 Resources, LLC assumed all of 76 Resources, Inc.’s obligations

104

 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
under the Smith Agreement by novation. Under the terms of the Smith Agreement, 76 Resources, LLC (as ultimate successor in interest to KMSmith), through Mr. Smith,
performs the duties and responsibilities of the CEO of the Company and related services, for an indefinite term at a base rate of $297,000 per year, generally payable in
equal monthly installments of $24,750. During fiscal 2023, the Smith Agreement was amended to increase the base rate to $325,000 per year. Any bonuses and incentive
payments are payable at the discretion of the Board. Mr. Smith is eligible to receive Options under the 2017 Amended Long-Term Incentive Plan, as determined by the
Board.

The Company may terminate the Smith Agreement at any time without notice or payment if (1) 76 Resources, LLC commits a material breach of the Smith Agreement
(subject to a cure period in certain circumstances), (2) Mr. Smith dies or becomes permanently disabled, or (3) certain other “for cause” scenarios occur (as further described
in the Smith Agreement). In the event the Smith Agreement is terminated by the Company for any other reason or if 76 Resources, LLC terminates the Smith Agreement on
the occurrence of a Triggering Event, the Company shall pay 76 Resources, LLC a lump sum termination fee equal to the base fee in effect at the termination date as well as
the average of any annual bonuses or other cash incentive payments for two calendar years immediately preceding the year the termination occurs. A Triggering Event is
defined as: a substantial change in the nature of services to be performed by 76 Resources, LLC; a material breach by the Company of the Smith Agreement that is not
remedied  within  30  days  of  notice;  the  cessation  of  the  Company  as  a  going  concern;  the  failure  of  the  Company  to  pay  a  material  amount  due  pursuant  to  the  Smith
Agreement within 30 days of the due date; or a material reduction in base fee or any other form of compensation payable by the Company to 76 Resources, LLC, except
where all senior executives or consultants of the Company are subject to relatively similar reductions in such values. 76 Resources, LLC may terminate the Smith Agreement
for a reason other than a Triggering Event on 90 days’ written notice and, should the Company immediately accept such termination notice, it shall pay 76 Resources, LLC
the sum of $69,904. Should a change of control of the Company occur (as that term is defined in the Smith Agreement) and, within one year, either a Triggering Event
occurs and 76 Resources, LLC terminates the Smith Agreement or 76 Resources, LLC’s engagement is terminated by the Company under circumstances that would give rise
to  a  termination  payment  in  the  absence  of  a  change  of  control,  then  76  Resources,  LLC  shall  be  entitled  to  receive  an  amount  equal  to  the  base  fee  in  effect  at  the
termination date as well as the average of any annual bonuses or other cash payments for two calendar years immediately preceding the year the termination occurs. In the
event 76 Resources, LLC is entitled to a termination payment with respect to a change of control, any Options previously granted to Mr. Smith shall become fully vested and
shall  remain  exercisable  for  the  original  term  of  grant  despite  a  termination  of  76  Resources,  LLC.  Termination  payments  under  the  Smith  Agreement  are  generally
contingent on a release of claims by 76 Resources, LLC. The Smith Agreement also includes customary confidentiality and six-month employee non-solicitation provisions.

If the Smith Agreement is terminated by the Company for any reason other than as set out in the Smith Agreement, if 76 Resources, LLC terminates the Smith Agreement on
the occurrence of a Triggering Event, or should a change of control of the Company occur and within one year, either a Triggering Event occurs and 76 Resources, LLC
terminates  the  Smith  Agreement  or  76  Resources,  LLC’s  engagement  is  terminated  without  the  occurrence  of  a  Triggering  Event,  effective  as  of  June  30,  2023,  76
Resources, LLC (as ultimate successor in interest to KMSmith) would have been entitled to a payment of $325,000.

As previously disclosed, on September 25, 2022, in connection with our entry into the Business Combination Agreement, Messrs. Shah and Honan (the “Covered Officers”)
entered into employment agreements with a United States affiliate (the “U.S. Affiliate”) of the Company (the “Employment Agreements”). The Employment Agreements
became  effective  upon  the  closing  of  the  GXII  Transaction,  and  will  continue  until  either  the  Covered  Officer  or  the  U.S.  Affiliate  terminates  the  Covered  Officer’s
employment for any reason. Pursuant to the Employment Agreements, Mr. Shah continues to serve as Chief Financial Officer of the Company, and Mr. Honan continues to
serve as the COO of the Company and serves as President of the U.S. Affiliate.

The Employment Agreement for Mr. Shah provides for an annual base salary of $220,000 per year, and Mr. Honan’s Employment Agreement provides for an annual base
salary of $260,000 per year. The annual base salary rates for the Covered Officers will be reviewed at least annually for potential increases. As described above, the base
salary rates of Messrs. Shah and Honan were increased in fiscal 2023. The Employment Agreements also provide each of the Covered Officers with eligibility to participate
in (1) any annual cash bonus plan and/or any long-term incentive compensation plan as may be established by the U.S. Affiliate or its affiliates, and (2) any employee benefit
plan,  program,  or  policy  of  the  U.S. Affiliate  or  its  affiliates  as  may  be  in  effect  for  senior  executives  of  the  U.S. Affiliate  or  its  affiliates  generally.  The  Employment
Agreements also include the following additional features: (1) severance benefits upon certain qualifying terminations of employment, consisting of: (a) for a qualifying
termination of the

105

 
  
 
 
 
 
 
Covered Officer’s employment by the U.S. Affiliate without Cause (as such term is defined in the Employment Agreements) that does not occur within two years after a
Change  in  Control  of  the  U.S. Affiliate  (as  defined  in  the  Employment Agreements),  certain  accrued  obligations,  plus  12  months  of  salary  continuation,  and  (b)  for  a
qualifying termination of the Covered Officer’s employment by the U.S. Affiliate without Cause or by the Covered Officer for Good Reason (as such term is defined in the
Employment Agreements) that occurs within two years after a Change in Control (a “Change in Control Termination”), certain accrued obligations, and a lump sum cash
amount equal to two times the Covered Officer’s annual base salary as in effect at the time of such termination; and (2) a requirement that each Covered Executive execute a
customary  release  of  claims  in  favor  of  the  U.S.  Affiliate  to  receive  severance  compensation.  In  connection  with  the  Covered  Officers  entering  into  the  Employment
Agreements  each  Covered  Officer  also  entered  into  a  restrictive  covenant  agreement  (a  “Restrictive  Covenant Agreement”).  The  Restrictive  Covenant Agreements  will
include customary restrictive covenants, including non-competition and non-solicitation obligations that remain in effect both during the employment term and for one year
following termination of the Covered Officer’s employment other than a Change in Control Termination (in which case the period will be two years following such Change
in Control Termination), as well as other customary restrictive covenants, such as confidentiality provisions.

Stock Options Under the 2017 Amended Long-Term Incentive Plan

In accordance with the 2017 Amended Long-Term Incentive Plan, the Company granted Options to its named executive officers during the Company’s 2023 fiscal year;

no other equity-based awards were granted to the named executive officers during the 2023 fiscal year.

The following table sets forth the outstanding equity awards for each named executive officer at June 30, 2023. The Company has not granted full value stock-based

(1) In connection with a reverse stock split effected by the Company on March 17, 2023, each then-outstanding Option then held by our named executive officers was
adjusted as follows:  (a) the number of shares subject to each such Option was divided by ten, with the resulting number rounded down to the nearest whole share;
and (b) the exercise price applicable to each such outstanding Option was multiplied by ten, with the resulting price rounded up to the nearest whole cent. The
amounts set forth in the table above with respect to options granted prior to March 27, 2023 reflect such adjustments.

(2) Option exercise price based on a spot exchange rate of C$1.324 to US$1.00 on June 30, 2023.

Messrs. Honan and Shah are each eligible to participate in the Company’s 401(k) savings plan, which is designed to reward continued employment with the Company and
assist participants with financial preparation for retirement. All amounts credited under the 401(k) savings plan relate to participant contributions. The Company does not
currently make matching or other contributions to the 401(k) savings plan.

Termination and Change of Control Benefits

Except as described above, the Company has not entered into any plans or arrangements in respect of remuneration received or that may be received by the named executive
officers in respect of compensating such officers or directors in the event of a change of control, termination of employment (as a result of resignation, retirement, change of
control, etc.) or a change in responsibilities following a change of control. Options are generally subject to clawback provisions, and provide for post-employment exercise
periods, pursuant to the terms of such awards and the 2017 Amended Long-Term Incentive Plan.

The Company has maintained equity compensation plans under which Options have been granted. Option grants have been determined by the Company’s directors and are
only provided in compliance with applicable laws and regulatory policy. The following information is provided with respect to compensation plans (including individual
compensation arrangements) under which equity securities were authorized for issuance as of June 30, 2023.

PERFORMANCE GRAPH

Overall, the Company’s cumulative return for the five-year period ended slightly below the range of returns for the two selected indices. As an exploration stage company,

February 2023, except for increases supported by additional job responsibilities and/or job promotions. Effective September 1, 2019, the Board approved a 10% base rate
increase for all NioCorp employees and effective April 1, 2023, the Compensation Committee approved a base rate average increase of 12% for all NioCorp employees.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

The following sets forth certain information regarding transactions between the Company (and its subsidiaries) and its officers, directors, and significant shareholders. There
have been no other transactions since the end of the Company’s most recently completed fiscal year and there are no currently proposed transactions in which the Company
was or is to be a participant and the amount involved exceeds $120,000, and in which any related person (for purposes of Item 404 of Regulation S-K) had or will have a
direct or indirect material interest.

Loan Transactions:

Mr. Smith is our Chief Executive Officer, President, Executive Chairman, and Director. On January 16, 2017, the Company and Mr. Smith entered into a credit agreement
(the “Smith Credit Agreement”) pursuant to which Mr. Smith agreed to make available to the Company a credit facility of initially up to $2,000,000. On January 17, 2020,
the  Company  entered  into  an  amending  agreement  to  the  Smith  Credit  Agreement,  increasing  the  limit  of  the  credit  facility  to  $2,500,000  from  the  previous  limit  of
$2,000,000. On April 3, 2020, the Smith Credit Agreement was amended to increase the limit of the credit facility to $3,000,000 and on June 10, 2020, the Smith Credit
Agreement  was  amended  to  increase  the  limit  of  the  credit  facility  to  $3,500,000.  In  addition,  on  June  10,  2020,  the  maturity  date  for  the  Smith  Credit Agreement  was

maturity date for the Smith Credit Agreement was extended to June 30, 2022. On June 29, 2022, the maturity date for the Smith Credit Agreement was extended to June 30,
2023. On February 28, 2023, the Smith Credit Agreement was amended to increase the borrowing limit to $4,000,000 from the previous limit of $3,500,000. The Company
subsequently drew down $1,130,000, leaving an available balance under the Smith Credit Agreement of $52,000.

The largest aggregate amount of principal outstanding under the Smith Credit Agreement during the years ended June 30, 2023 and 2022 was $3,130,000 and $2,318,000,
respectively. Principal repayments of $3,130,000 and $318,000 were made under the Smith Credit Agreement during the years ended June 30, 2023 and 2022, respectively.
In addition, interest payments of $183,343 and $251,741 were paid under the Smith Credit Agreement during the years ended June 30, 2023 and 2022, respectively, and $0
of interest remained payable as of June 30, 2023. As of June 30, 2023, all principal and accrued interest outstanding under the Smith Credit Agreement had been repaid and
the Smith Credit Agreement expired on June 30, 2023. Accounts payable and accrued liabilities as of June 30, 2023, includes $28,250 of origination fees payable under the

Review, Approval or Ratification of Related Person Transactions

transaction required to be reported under Item 404(a) of Regulation S-K. Sections 147-153 of the BCBCA set out rules and procedures applicable to all British Columbia
corporations, pursuant to which a director presented with a resolution in respect of any matter (including an equity issuance) in respect of which he/she has an interest must
disclose that interest in writing to the corporation’s board of directors prior to the approval of such matter. This procedure ensures that each equity issuance to a director or
officer of the Company is approved by all directors of the Company not involved in such sale. All loan transactions from directors and officers are subject to review and
approval by the Board prior to acceptance and are documented in the meeting minutes.

“Audit Fees” include fees necessary to perform the annual audit and quarterly reviews of the Company’s consolidated financial statements. Audit Fees include fees
for review of tax provisions and for accounting consultations on matters reflected in the consolidated financial statements. Audit Fees also include audit or other
attest services required by legislation or regulation, such as comfort letters, consents, reviews of securities filings and statutory audits.

“Audit-Related  Fees”  include  services  that  are  traditionally  performed  by  the  auditor. These  audit-related  services  include  employee  benefit  audits,  due  diligence
assistance, accounting consultations on proposed transactions, internal control reviews and audit or attest services not required by legislation or regulation.

Pre-approval Policies

The  policy  of  the  Audit  Committee  of  the  Board  (the  “Audit  Committee”)  has  been  to  pre-approve  all  audit,  audit-related  and  non-audit  services  performed  by  our
independent auditors and to subsequently review the actual fees and expenses paid to our independent auditors. Accordingly, the Audit Committee pre-approved all audit,
audit-related and non-audit services performed by BDO and subsequently reviewed the actual fees and expenses paid to BDO. The Audit Committee has determined that the
fees paid to BDO for services are compatible with maintaining BDO’s independence as our auditors. All of the services provided by BDO during the year ended June 30,
2023, were approved by the Audit Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Common Shares

DESCRIPTION OF SECURITIES

The authorized capital of NioCorp Developments Ltd., a British Columbia corporation (the “Company”), consists of an unlimited number of Common Shares, without
par value. The holders of Common Shares are entitled to receive notice of and attend all meetings of shareholders, with each Common Share held entitling the holder to one
vote on any resolution to be passed at such shareholder meetings. The holders of Common Shares are entitled to dividends if, as and when declared by the Company’s Board
of Directors. The Common Shares are entitled, upon liquidation, dissolution, or winding up of the Company, to receive the remaining assets of the Company available for
distribution to shareholders. There are no pre-emptive, conversion, or redemption rights attached to the Common Shares.

Exchange Controls

There are no governmental laws, decrees, or regulations in Canada that restrict the export or import of capital, including foreign exchange controls, or that affect the
remittance of dividends, interest or other payments to non-resident holders of the securities of the Company, other than as discussed below and Canadian withholding tax.
See “Certain Canadian Federal Income Tax Considerations for U.S. Residents” below.

Competition Act

Limitations on the ability to acquire and hold Common Shares may be imposed by the Competition Act (Canada). This legislation permits the Commissioner of
Competition of Canada (the “Commissioner”) to review any acquisition of a significant interest in the Company. This legislation grants the Commissioner jurisdiction to
challenge such an acquisition before the Canadian Competition Tribunal if the Commissioner believes that it would, or would be likely to, result in a substantial lessening or
prevention of competition in any market in Canada.

Investment Canada Act

The Investment Canada Act subjects an acquisition of control of a company by a non-Canadian to government review if the enterprise value (or in some cases, asset

value) of such company, as calculated pursuant to the legislation, exceeds a threshold amount. A reviewable acquisition may not proceed unless the relevant minister is
satisfied that the investment is likely to result in a net benefit to Canada. Under the national-security-review regime in the Investment Canada Act, review on a discretionary
basis may also be undertaken by the federal government in respect of a broad range of investments by a non-Canadian. No financial threshold applies to a national security
review. The relevant test is whether such investment by a non-Canadian could be “injurious to national security.”

Certain Canadian Federal Income Tax Considerations for U.S. Residents

The following generally summarizes certain Canadian federal income tax consequences generally applicable under the Income Tax Act (Canada) and the regulations

enacted thereunder (collectively, the “Canadian Tax Act”) and the Canada-United States Tax Convention (1980) (the “Convention”) to the holding and disposition of
Common Shares.

Comment is restricted to holders of Common Shares each of whom, at all material times for the purposes of the Canadian Tax Act and the Convention, (i) is resident

solely in the United States for tax purposes, (ii) is a “qualifying person” under and entitled to the benefits of the Convention, (iii) holds all Common Shares as capital
property, (iv) holds no Common Shares that are “taxable Canadian property” (as defined in the Canadian Tax Act) of the holder, (v) deals at arm’s length with and is not
affiliated with the Company, (vi) does not and is not deemed to use or hold any Common Shares in a business carried on in Canada, (vii) is not an insurer that carries on
business in Canada and elsewhere, and (viii) is not an “authorized foreign bank” (as defined in the Canadian Tax Act) (each such holder, a “U.S. Resident Holder”).

Certain U.S.-resident entities that are fiscally transparent for United States federal income tax purposes (including limited liability companies) may not in all

circumstances be entitled to the benefits of the Convention.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Members of or holders of an interest in such an entity that holds Common Shares should consult their own tax advisers regarding the extent, if any, to which the benefits of
the Convention will apply to the entity in respect of its Common Shares.

Generally, a U.S. Resident Holder’s Common Shares will be considered to be capital property of such holder provided that the U.S. Resident Holder is not a trader

or dealer in securities, did not acquire, hold, or dispose of the Common Shares in one or more transactions considered to be an adventure or concern in the nature of trade
(i.e., speculation) and does not hold the Common Shares in the course of carrying on a business.

This summary is based on the current provisions of the Canadian Tax Act and the Convention in effect as of the date prior to the date hereof, all specific proposals
to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, and the current published
administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”). It is assumed that all such amendments will be enacted as currently proposed,
and that there will be no other material change to any applicable law or administrative policy or assessing practice, whether by way of judicial, legislative or governmental
decision or action, although no assurance can be given in these respects. This summary is not exhaustive of all possible Canadian federal income tax considerations. Except
as otherwise expressly provided, this summary does not take into account any provincial, territorial, or foreign tax considerations, which may differ materially from those set
out herein.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations, and is not intended to be and should not be

construed as legal or tax advice to any particular U.S. Resident Holder. U.S. Resident Holders are urged to consult their own tax advisers for advice with respect to their
particular circumstances. The discussion below is qualified accordingly.

Generally, a U.S. Resident Holder’s Common Shares will not constitute “taxable Canadian property” of such holder at a particular time at which the Common

Shares are listed on a “designated stock exchange” (which currently includes the Toronto Stock Exchange (the “TSX”) and the Nasdaq) unless both of the following
conditions are concurrently met:

(i) at any time during the 60-month period that ends at the particular time, 25% or more of the issued shares of any class of the capital stock of the Company were

owned by or belonged to one or any combination of:

(A) the U.S. Resident Holder;

(B) persons with whom the U.S. Resident Holder did not deal at arm’s length; and

(C) partnerships in which the U.S. Resident Holder or a person referred to in clause (B) holds a membership interest directly or indirectly through one or more

partnerships; and

(ii) at any time during the 60-month period that ends at the particular time, more than 50% of the fair market value of the Common Shares was derived directly or

indirectly from, one or any combination of, real or immovable property situated in Canada, “Canadian resource properties” (as defined in the Canadian Tax Act),
“timber resource properties” (as defined in the Canadian Tax Act), or options in respect of, or interests in any of the foregoing, whether or not the property exists.

Common Shares may also be deemed to be “taxable Canadian property” in certain circumstances set out in the Canadian Tax Act.

A U.S. Resident Holder who disposes or is deemed to dispose of one or more Common Shares generally should not thereby incur any liability for Canadian federal

income tax in respect of any capital gain arising as a consequence of the disposition.

A U.S. Resident Holder to whom the Company pays or credits or is deemed to pay or credit a dividend on such holder’s Common Shares will be subject to Canadian

withholding tax, and the Company will be required to

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
withhold the tax from the dividend and remit it to the CRA for the holder’s account. The rate of withholding tax under the Canadian Tax Act is 25% of the gross amount of
the dividend, but should generally be reduced under the Convention to 15% (or, if the U.S. Resident Holder is a company which is the beneficial owner of at least 10% of the
voting stock of the Company, 5%) of the gross amount of the dividend. For this purpose, a company that is a resident of the United States for purposes of the Canadian Tax
Act and the Convention and is entitled to the benefits of the Convention shall be considered to own the voting stock of the Company owned by an entity that is considered
fiscally transparent under the laws of the United States and that is not a resident of Canada, in proportion to such company’s ownership interest in that entity.

Warrants

From time to time, the Company has outstanding Common Share purchase warrants, with each Common Share purchase warrant exercisable for one Common Share.
The exercise price per Common Share and the number of Common Shares issuable upon exercise of Common Share purchase warrants is subject to adjustment upon the
occurrence of certain events, including, but not limited to, the following:

● the subdivision or re-division of the outstanding Common Shares into a greater number of Common Shares;

● the reduction, combination or consolidation of the outstanding Common Shares into a lesser number of Common Shares;

● the issuance of Common Shares or securities exchangeable for, or convertible into, Common Shares to all or substantially all of the holders of Common Shares by
way of stock dividend or other distribution (other than a distribution of Common Shares upon the exercise of Common Share purchase warrants or any outstanding
options);

● the reorganization of the Company or the consolidation or merger or amalgamation of the Company with or into another corporate body; and

● a reclassification or other similar change to the outstanding Common Shares.

The Company will issue the Common Shares issuable upon exercise of Common Share purchase warrants within five business days following its receipt of notice of
exercise and payment of the exercise price, subject to surrender of the Common Share purchase warrants. Prior to the exercise of any Common Share purchase warrants,
holders of the Common Share purchase warrants will not have any of the rights of holders of the Common Shares issuable upon exercise, including the right to vote or to
receive any payments of dividends on the Common Shares issuable upon exercise.

NioCorp Assumed Warrants

On March 17, 2023 (the “Closing Date”), the Company closed a series of transactions (the “GXII Transaction”) pursuant to the Business Combination Agreement, dated

as of September 25, 2022 (the “Business Combination Agreement”), by and among the Company, GX Acquisition Corp. II, a Delaware corporation (“GXII”), and Big Red
Merger Sub Ltd., a Delaware corporation and a direct, wholly owned subsidiary of the Company. In connection with the closing of the GXII Transaction (the “Closing”),
pursuant to the Business Combination Agreement, the Company assumed GXII’s obligations under the Warrant Agreement, dated as of March 17, 2021 (the “GXII Warrant
Agreement”), by and between GXII and Continental Stock Transfer & Trust Company (“CST”), as warrant agent, and each share purchase warrant of GXII thereunder (the
“GXII Warrants”) that was issued and outstanding immediately prior to the Closing Date was converted into one Common Share purchase warrant (the “NioCorp Assumed
Warrants”) pursuant to the GXII Warrant Agreement, as amended by an Assignment, Assumption and Amendment Agreement, dated the Closing Date (the GXII Warrant
Agreement, as so amended, the “NioCorp Assumed Warrant Agreement”), among the Company, GXII, CST, as existing warrant agent, and Computershare Inc. and its
affiliate Computershare Trust Company, N.A, together as successor warrant agent (the “NioCorp Assumed Warrant Agent”). In connection with the Closing, NioCorp issued
(a) 9,999,959 public NioCorp Assumed Warrants in respect of the GXII Warrants that were publicly traded prior to the Closing and (b) 5,666,667 NioCorp Assumed
Warrants to GX Sponsor II LLC (the “Sponsor”) in respect of the GXII Warrants that it held prior to the

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Closing, which NioCorp Assumed Warrants were subsequently distributed by the Sponsor to its members in connection with the Closing.

Both the public NioCorp Assumed Warrants and the NioCorp Assumed Warrants issued to the Sponsor are subject to the terms of the NioCorp Assumed Warrant

Agreement and are identical, with certain exceptions applicable to the NioCorp Assumed Warrants issued to the Sponsor for so long as such NioCorp Assumed Warrants are
held by the Sponsor, its members, or their respective affiliates and other permitted transferees. In accordance with the NioCorp Assumed Warrant Agreement, any NioCorp
Assumed Warrants issued to the Sponsor that are held by someone other than the Sponsor, its members, or their respective affiliates and other permitted transferees, are
treated as public NioCorp Assumed Warrants.

Each NioCorp Assumed Warrant is exercisable on and after April 16, 2023 until its expiration for 1.11829212 Common Shares at a price of $11.50 per 1.11829212
Common Shares (subject to adjustments for stock splits, stock dividends, reorganizations, recapitalizations and the like). Under the terms of NioCorp Assumed Warrant
Agreement, for so long as the NioCorp Assumed Warrants issued to the Sponsor are held by the Sponsor, its members, or their respective affiliates and other permitted
transferees, such holders have the right to elect to exercise those NioCorp Assumed Warrants on a cashless basis. For such NioCorp Assumed Warrants exercised on a
cashless basis after the Closing, the holder will be entitled to pay the exercise price for those NioCorp Assumed Warrants by surrendering all or portion of the cash and/or
Common Shares (valued at their fair market value) into which those NioCorp Assumed Warrants are exercisable as shall be elected by the holder. For this purpose, Common
Shares so surrendered will be deemed to have a “fair market value” equal to the average reported last sale price of the Common Shares for the 10 trading days ending on the
third trading day prior to the date of exercise of the applicable NioCorp Assumed Warrants.

The NioCorp Assumed Warrants will expire at 5:00 p.m., New York City time, on March 17, 2028 or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Common Shares pursuant to the exercise of a NioCorp Assumed Warrant and will have no obligation to settle such

exercise unless a registration statement under the Securities Act with respect to the Common Shares underlying the NioCorp Assumed Warrants is then effective and a
prospectus relating thereto is current, subject to the Company satisfying its obligations described below with respect to registration. No NioCorp Assumed Warrant will be
exercisable and the Company will not be obligated to issue Common Shares upon exercise of a NioCorp Assumed Warrant unless Common Shares issuable upon such
exercise have been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the NioCorp Assumed Warrants.
In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a NioCorp Assumed Warrant, the holder of such NioCorp
Assumed Warrant will not be entitled to exercise such NioCorp Assumed Warrant and such NioCorp Assumed Warrant may have no value and expire worthless. In no event
will the Company be required to net cash settle any NioCorp Assumed Warrant.

The NioCorp Assumed Warrants, and the underlying Common Shares issuable upon the exercise thereof, were registered under the Securities Act pursuant to the
Company’s registration statement on Form S-4, originally filed on November 7, 2022, as subsequently amended, which was declared effective by the SEC on February 8,
2023. The Company expects the ongoing registered offering of the Common Shares underlying the NioCorp Assumed Warrants to be conducted pursuant to the Company’s
registration statement on Form S-3, which was filed on April 14, 2023 and which the Company expects to post-effectively amend to convert such registration statement to
Form S-1.

The Company will have the right to call the public NioCorp Assumed Warrants for redemption at any time following the Closing Date:

●

●

●

in whole and not in part;

at a price of $0.01 per NioCorp Assumed Warrant;

upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each public NioCorp Assumed Warrant holder;

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
●

●

if, and only if, the reported last sale price of the Common Shares equals or exceeds approximately $16.10 per share (subject to certain adjustments) for any
20 trading days within a 30-trading day period commencing once the NioCorp Assumed Warrants become exercisable and ending three business days before
the Company sends the notice of redemption to the public NioCorp Assumed Warrant holders; and

if there is an effective registration statement covering the Common Shares issuable upon exercise of the NioCorp Assumed Warrants, and a current
prospectus relating thereto, available throughout the 30-day redemption period.

The NioCorp Assumed Warrants issued to the Sponsor are not redeemable by the Company for so long as such NioCorp Assumed Warrants are held by the Sponsor, its

members, or their respective affiliates or other permitted transferees. In addition, the Company may not exercise its redemption right if the issuance of Common Shares upon
exercise of the NioCorp Assumed Warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such
registration or qualification.

If the Company calls the public NioCorp Assumed Warrants for redemption as described above, the Company will have the option to require any holder that wishes to

exercise its public NioCorp Assumed Warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their public NioCorp Assumed
Warrants on a “cashless basis,” the Company will consider, among other factors, its cash position, the number of NioCorp Assumed Warrants that are outstanding and the
dilutive effect on the Company’s shareholders of issuing the maximum number of Common Shares issuable upon the exercise of the NioCorp Assumed Warrants. If the
Company takes advantage of this option, all holders of public NioCorp Assumed Warrants would pay the exercise price by surrendering their NioCorp Assumed Warrants for
that number of Common Shares equal to the quotient obtained by dividing (x) the product of the number of Common Shares underlying the public NioCorp Assumed
Warrants, multiplied by the difference between the exercise price of the NioCorp Assumed Warrants and the “fair market value” (defined below) by (y) the fair market value.
The “fair market value” shall mean the average reported last sale price of the Common Shares for the 10 trading days ending on the third trading day prior to the date on
which the notice of redemption is sent to the holders of public NioCorp Assumed Warrants. If the Company takes advantage of this option, the notice of redemption will
contain the information necessary to calculate the number of Common Shares to be received upon exercise of the NioCorp Assumed Warrants, including the “fair market
value” in such case. Requiring a cashless exercise in this manner will reduce the number of Common Shares to be issued and thereby lessen the dilutive effect of a
redemption of the public NioCorp Assumed Warrants. If the Company calls the public NioCorp Assumed Warrants for redemption and does not take advantage of this
option, the Sponsor, its members, and their respective affiliates and other permitted transferees would still be entitled to exercise their NioCorp Assumed Warrants for cash
or on a cashless basis using the same formula described above that other NioCorp Assumed Warrant holders would have been required to use had all NioCorp Assumed
Warrant holders been required to exercise their NioCorp Assumed Warrants on a cashless basis, as described in more detail below.

A holder of a NioCorp Assumed Warrant may notify the Company in writing in the event it elects to be subject to a requirement that such holder will not have the right

to exercise such NioCorp Assumed Warrant, to the extent that after giving effect to such exercise, such holder (together with such holder’s affiliates), to the NioCorp
Assumed Warrant Agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the Common Shares
outstanding immediately after giving effect to such exercise.

The NioCorp Assumed Warrants have certain anti-dilution and adjustments rights upon certain events.

The NioCorp Assumed Warrants may be exercised upon surrender of the certificate representing such NioCorp Assumed Warrants on or prior to the expiration date at

the offices of the NioCorp Assumed Warrant Agent, with the exercise form on the reverse side of such certificate completed and executed as indicated, accompanied by full
payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to the order of the NioCorp Assumed Warrant Agent or by
wire transfer, for the number of NioCorp Assumed Warrants being exercised. The NioCorp Assumed Warrant holders will not have the rights or privileges of holders of
Common Shares or any attendant voting rights until they exercise their NioCorp Assumed Warrants and receive Common Shares. After the issuance of Common Shares
upon exercise of the NioCorp Assumed Warrants, each

 
 
 
 
 
 
 
 
 
 
 
 
holder will be entitled to one vote for each Common Share held of record on all matters to be voted on by NioCorp shareholders.

If, upon exercise of the NioCorp Assumed Warrants, a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round down

to the nearest whole number of Common Shares to be issued to the NioCorp Assumed Warrant holder.

The NioCorp Assumed Warrants were issued in registered form under the NioCorp Assumed Warrant Agreement. The NioCorp Assumed Warrant Agreement may be
amended by the parties thereto without the consent of any registered holder (i) for the purpose of curing any ambiguity, or curing, correcting or supplementing any mistake,
or adding or changing any other provisions with respect to matters or questions arising under NioCorp Assumed Warrant Agreement as the parties may deem necessary or
desirable and that the parties deem shall not adversely affect the interest of the registered holders of the NioCorp Assumed Warrants, and (ii) to provide for the delivery of
such kind and amount of Common Shares or other securities or property (including cash) receivable upon a reclassification, reorganization, merger or consolidation, or upon
a dissolution following any such sale or transfer, that the holder of NioCorp Assumed Warrants would have received if such holder had exercised his, her or its NioCorp
Assumed Warrants immediately prior to such event. All other modifications or amendments, including any amendment to increase the warrant price or shorten the exercise
period, shall require the vote or written consent of the registered holders of a majority of the then outstanding public NioCorp Assumed Warrants. Any amendment solely to
the NioCorp Assumed Warrants issued to the Sponsor and that are held by the Sponsor, its members, or their respective affiliates or other permitted transferees, shall require
the vote or written consent of a majority of the holders of the then outstanding NioCorp Assumed Warrants issued to the Sponsor.

Convertible Debentures

On January 26, 2023, NioCorp entered into a Securities Purchase Agreement (as amended, the “Yorkville Convertible Debt Financing Agreement”) with YA II PN, Ltd.

(“YA”). Pursuant to the Yorkville Convertible Debt Financing Agreement, YA advanced a total amount of $15,360,000 to NioCorp in consideration of the issuance by
NioCorp to YA of $16,000,000 aggregate principal amount of unsecured convertible debentures (the “Convertible Debentures”) at the time of Closing (the “Debenture
Closing”). As of [September [27]], 2023, there was $8,000,000 aggregate principal amount of Convertible Debentures outstanding.

Each Convertible Debenture issued under the Yorkville Convertible Debt Financing Agreement is an unsecured obligation of NioCorp, matures on September 17, 2024,
which maturity may be extended for one six-month period in certain circumstances at the option of NioCorp, and incurs a simple interest rate obligation of 5.0% per annum
(which will increase to 15.0% per annum upon the occurrence of an event of default). The outstanding principal amount of, accrued and unpaid interest, if any, on, and
premium, if any, on the Convertible Debentures must be paid by NioCorp in cash when the same becomes due and payable under the terms of the Convertible Debentures at
their stated maturity, upon their redemption or otherwise.

Subject to certain limitations contained within the Yorkville Convertible Debt Financing Agreement and the Convertible Debentures, including those as described below,
holders of the Convertible Debentures will be entitled to convert the principal amount of, and accrued and unpaid interest, if any, on each Convertible Debenture, in whole or
in part, from time to time over their term, into a number of Common Shares equal to the quotient of the principal amount and accrued and unpaid interest, if any, being
converted divided by the Conversion Price. The “Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, the greater of (i)
90% of the average of the daily U.S. dollar volume-weighted average price of the Common Shares on the principal U.S. market for the Common Shares as reported by
Bloomberg Financial Markets during the five consecutive trading days

 
 
 
 
 
 
 
 
 
 
immediately preceding the date on which the holder exercises its conversion right in accordance with the requirements of the Yorkville Convertible Debt Financing
Agreement (the “Conversion Date”) or other date of determination, but not lower than the Floor Price (as defined below), and (ii) the five-day volume-weighted average
price of the Common Shares on the TSX (or on the principal U.S. market if the majority of the trading volume and value of the Common Shares occurred on Nasdaq during
the relevant period) for the five consecutive trading days immediately prior to the Conversion Date or other date of determination less the maximum applicable discount
allowed by the TSX. The “Floor Price” means a price of $2.1435 per share, which is equal to the lesser of (a) 30% of the average of the daily volume-weighted average price
of the Common Shares on the principal U.S. market for the Common Shares as reported by Bloomberg Financial Markets during the five consecutive trading days
immediately preceding the Debenture Closing and (b) 30% of the average of the volume-weighted average price of the Common Shares on the principal U.S. market for the
Common Shares as reported by Bloomberg Financial Markets during the five consecutive trading days immediately following the Debenture Closing, subject to certain
adjustments to give effect to any stock dividend, stock split, reverse stock split, recapitalization or similar event.

The terms of the Convertible Debentures restrict the number of Convertible Debentures that may be converted during each calendar month by YA at a Conversion Price
below a fixed price equal to approximately $8.9422 (i.e., the quotient of $10.00 divided by 1.11829212 (being the number of Common Shares that were exchanged for each
share of GXII at the Closing, after giving effect to the Reverse Stock Split)), subject to adjustment to give effect to any stock dividend, stock split, reverse stock split,
recapitalization or similar event. The Convertible Debentures are subject to customary anti-dilution adjustments.

The terms of the Convertible Debentures restrict the conversion of Convertible Debentures by YA if such a conversion would cause YA to exceed certain beneficial
ownership thresholds in NioCorp or such a conversion would cause the aggregate number of Common Shares issued pursuant to the Yorkville Convertible Debt Financing
Agreement to exceed the thresholds for issuance of Common Shares under the rules of the TSX and Nasdaq, unless prior shareholder approval is obtained.

Financing Warrants

In conjunction with the Debenture Closing, NioCorp issued to YA Common Share purchase warrants (the “Financing Warrants”) to purchase 1,789,267 Common

Shares, which is equal to the quotient of the principal amount of Convertible Debentures issued in such Debenture Closing divided by the “Exercise Price,” which is equal to
approximately $8.9422 (i.e., the quotient of $10.00 divided by 1.11829212 (being the number of Common Shares that were exchanged for each share of GXII at the Closing,
after giving effect to the Reverse Stock Split)), in each case, subject to adjustment to give effect to any stock dividend, stock split, reverse stock split, recapitalization or
similar event.

The Financing Warrants are exercisable, in whole or in part, but not in increments of less than $50,000 aggregate Exercise Price (unless the remaining aggregate
Exercise Price is less than $50,000), beginning on May 4, 2023, and may be exercised at any time prior to their expiration. Holders of the Financing Warrants may exercise
their Financing Warrants, at their election, by paying the Exercise Price in cash or, if at any time there is no effective registration statement registering, or no current
prospectus available for, the resale of the underlying Common Shares, on a cashless exercise basis. On each of the first 12 monthly anniversaries of September 17, 2023,
1/12th of the Financing Warrants will expire.

The Financing Warrants have customary anti-dilution adjustments to be determined in accordance with the requirements of the applicable stock exchanges, including the

TSX.

The terms of the Financing Warrants restrict the exercise of Financing Warrants by YA if such an exercise would cause YA to exceed certain beneficial ownership
thresholds in NioCorp or such an exercise would cause the aggregate number of Common Shares issued pursuant to the Yorkville Convertible Debt Financing Agreement to
exceed the thresholds for issuance of Common Shares under the rules of the TSX and Nasdaq, unless prior shareholder approval is obtained.
