### **Notes to the Condensed Consolidated Financial Statements**

**December 31, 2024** 

(expressed in thousands of
U.S. dollars, except share and per share data or as otherwise stated) (unaudited)

1. DESCRIPTION OF BUSINESS

NioCorp Developments Ltd. (“we,”
“us,” “our,” “NioCorp” or the “Company”) 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 Company’s niobium, scandium, and titanium project
(the “Elk Creek Project”) located in southeastern Nebraska.

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 3, 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.

These interim condensed 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 financial statements do not reflect
any adjustments that may be necessary if the Company is unable to continue as a going concern.

2. BASIS OF PRESENTATION

a) Basis of Presentation and Consolidation

The accompanying interim condensed
consolidated financial statements have been prepared in accordance with generally accepted accounting principles of the United
States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”).
The interim condensed consolidated financial statements include the consolidated accounts of the Company and its wholly owned subsidiaries
with all significant intercompany transactions eliminated. The accounting policies followed in preparing these interim condensed
consolidated financial statements are those used by the Company as set out in the audited consolidated financial statements for
the year ended June 30, 2024. Certain transactions include reference to Canadian dollars (“C$”) where applicable.

In the opinion of management,
all adjustments considered necessary (including normal recurring adjustments) for a fair statement of the financial position, results
of operations, and cash flows at December 31, 2024, and for all periods presented, have been included in these interim condensed
consolidated financial statements. Certain information and footnote disclosures normally included in the consolidated financial
statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to appropriate SEC rules and regulations.
These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial
statements for the year ended June 30, 2024. The interim results are not necessarily indicative of results for the full year ending
June 30, 2025, or future operating periods.

b) Recent Accounting Standards

Issued and Not Effective

In November 2023, the Financial
Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting
(Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU expand public entities’ segment disclosures
by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker and included
within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and
interim disclosures of a reportable segment’s profit or loss and assets. The ASU will be effective for our annual report
for the period ending June 30, 2025, and for interim period reports beginning thereafter. We are currently evaluating the impact
of adopting this ASU on our consolidated financial statements and disclosures.

(expressed in thousands of
U.S. dollars, except share and per share data or as otherwise stated) (unaudited)

In December 2023, the FASB issued
ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness
of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is
effective for our annual report for the period ending June 30, 2027, and for interim period reports beginning thereafter. Early
adoption is permitted and the amendments should be applied prospectively; however, retrospective application is permitted. We are
currently evaluating the impact of this ASU on our consolidated financial statements and related disclosures.

In November 2024, the FASB issued
ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation
of Income Statement Expenses. ASU 2024-03 requires the disclosure of additional information related to certain costs and expenses,
including amounts of inventory purchases, employee compensation, and depreciation and amortization included in each income statement
line item. This ASU also requires disclosure of the total amount of selling expenses and our definition of selling expenses. This
ASU is effective for our annual report for the period ending June 30, 2028, and for interim period reports beginning thereafter
on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU
on our consolidated financial statements and disclosures.

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.

c) 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 financial statements,
and the reported amounts of expenses during the reporting period. The Company regularly evaluates estimates and assumptions related
to the carrying value of long-term assets, deferred income tax assets and related valuations, liabilities related to the April
2024 Notes, Earnout Shares, Private Warrants, November Public Warrants, and November Private Warrants (each, as defined below),
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.

The Company acquired a federal
income tax payable of $443 in connection with the GXII Transaction (as defined below). As a result of post-transaction losses at
Elk Creek Resources Corp. (“ECRC”), a partial release of the valuation allowance attributed to the reduction of the
acquired federal income tax payable of $101 was recorded as an income tax benefit in the condensed consolidated statement of operations
and comprehensive loss for the six months ended December 31, 2023. The Company maintains a full valuation allowance against future
income tax assets as it is more likely than not that all of the assets will not be realized.

d) Basic and Diluted Earnings per Share

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:

3. GOING CONCERN

The Company incurred a loss
of $2,521 for the six months ended December 31, 2024 (six months ended December 31, 2023 - $6,504) and had a working capital deficit
of $3,087 and an accumulated deficit of $164,433 as of December 31, 2024. As a development stage issuer, the Company has not yet
commenced its mining operations and accordingly does not generate any revenue. As of December 31, 2024, the Company had cash of
$477, which will not be sufficient to fund normal operations or the repayment of the April 2024 Notes (as further discussed in
Note 6b) for the next twelve months. These conditions and events raise substantial doubt about the Company’s ability to continue
as a going concern.

In response to these conditions
and events, the Company plans to obtain additional financing. As disclosed in Note 13, on January 31, 2025, the Company closed the January 2025 Offering (as defined below), which resulted in the receipt of net proceeds of approximately $5,000 before deducting underwriting discounts and offering expenses. The Company may pursue 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. The Company’s
plans

to obtain additional financing have not been finalized, are subject to market conditions, and are not within the Company’s
control and therefore cannot be deemed probable. Further, the Company will be required to raise additional funds for the construction
and commencement of operations. As a result, the Company has concluded that management’s plans do not alleviate substantial
doubt about the Company’s ability to continue as a going concern.

These interim condensed consolidated
financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts
or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

4. MINERAL PROPERTIES

During the quarter ended December 31, 2024,
the Company completed negotiations with four landowners in Nebraska and entered into contract amendments which extended the option
periods by approximately five years for each option to purchase agreement (“OTP”) covering four parcels of land for
project construction and operation which the Company does not already own. The Company paid $106 upon closing of the OTP extensions
and will make periodic payments totaling $184 over the extension period.

a) Yorkville Convertible Debenture

On July 19, 2024, the Company
and Yorkville entered into a make-whole payment agreement under which Yorkville agreed to convert the remaining outstanding principal
and accrued interest of $554 under the unsecured convertible debentures (the “Convertible Debentures”) issued to Yorkville
pursuant to the Securities Purchase Agreement, dated January 26, 2023 (the “Yorkville Convertible Debt Financing Agreement”),
into Common Shares in exchange for a $95 make-whole payment. The Company recorded a gain on extinguishment of $19 as part other

a securities purchase agreement, dated April 11, 2024 (the “April 2024 Purchase Agreement”), between the Company and
each of the April 2024 Purchasers. The Company also issued to the April 2024 Purchasers, in proportion to the aggregate principal
amount of April 2024 Notes issued to each April 2024 Purchaser, Warrants (the “April 2024 Warrants”) to purchase up
to 615,385 Common Shares, which are equal to 25% of the aggregate principal amount of April 2024 Notes issued to the April 2024

7. CLASS B COMMON STOCK OF ECRC

The shares of Class B common
stock of ECRC, an indirect, majority-owned subsidiary of NioCorp formerly known as GX Acquisition Corp. II (“GXII”),
include rights under which the holders may exchange such shares into Common Shares. Certain of such shares were vested as of the
Closing (as defined below) and are exchangeable at any time, from time to time, until the tenth anniversary of the Closing Date
(as defined below) (the “Vested Shares”) and certain of such shares are subject to certain vesting conditions (the
“Earnout Shares”).

*Earnout Shares*

The Earnout Shares were valued
utilizing a Monte Carlo Simulation pricing model with the following primary inputs:

| Key Valuation Input | December 31, 2024 | June 30, 2024 |
| --- | --- | --- |
| Closing Common Share price | $1.55 | $1.73 |
| Term (expiry) | March 17, 2033 | March 17, 2033 |
| Implied volatility of Public Warrants | 64.0% | 65.0% |
| Risk-free rate | 4.52% | 4.35% |

| Fair value at June 30, 2024 | $3,817 |
| Change in fair value | (753) |
| Fair value at December 31, 2024 | $3,064 |

*Vested Shares*

On December 12, 2024, and December
20, 2024, 25,000 Vested Shares and 323,085 Vested Shares, respectively, were exchanged for an equivalent number of Common Shares.
This exchange resulted in a change in the Company’s ownership interest in ECRC and was accounted for as an equity transaction
in accordance with Accounting Standards Codification (“ASC”) 810-10-45-23, with no gain or loss recognized. Accordingly,
the carrying amount of the noncontrolling interest was adjusted to reflect the change in the Company’s ownership interest
with a corresponding offset booked to equity. As of December 31, 2024, 3,934,031 Vested Shares remained outstanding.

8. COMMON SHARES

a) Issuance

On November 5, 2024, the
Company closed an underwritten public offering (the “November 2024 Registered Offering”), pursuant to the underwriting
agreement, dated November 3, 2024 (the “Underwriting Agreement”), with Maxim Group LLC, as underwriter (the “Underwriter”),
which consisted of 1,592,356 Common Shares, 1,672,090 Warrants (the “Series A Public Warrants”) to purchase up to an
additional 1,672,090 Common Shares and 836,045 Warrants (the “Series B Public Warrants” and, together with the Series
A Public Warrants, the “November Public Warrants”) to purchase up to an additional 836,045 Common Shares. Each Common
Share was sold together with one Series A Public Warrant and one-half of one Series B Public Warrant at a combined public offering
price of $1.57. The gross proceeds from the November 2024 Registered Offering were $2,501 before deducting underwriting
discounts and offering expenses. The November Public Warrants were classified as equity instruments and accordingly, the net proceeds were allocated based on the relative fair values of the Common Shares and the November Public Warrants on the date of issuance, with $943 allocated to the fair value of the November Public Warrants and the balance of the proceeds of $1,558 allocated to Common Shares. The Company incurred total transaction costs related to the November 2024 Registered Offering $1,226, which were treated as share issuance costs at closing. The Series A Public

Warrants have an exercise price of $1.75 per underlying Common Share, are
exercisable immediately, and will expire on November 5, 2026. The Series B Public Warrants have an exercise price of $2.07 per
underlying Common Share, are exercisable beginning six months and one day from the date of issuance and will expire on November
5, 2029. In addition, pursuant to the Underwriting Agreement, the Company granted the Underwriter a 45-day over-allotment option
to purchase (i) 238,853 additional Common Shares and (ii) 358,280 Option Warrants (as defined below) to purchase up to an aggregate
of 358,280 Common Shares. “Option Warrant” means one Series A Public Warrant combined with one-half of one Series B
Public Warrant. On November 4, 2024, the Underwriter partially exercised its over-allotment option to purchase 79,734 additional
Series A Public Warrants and 39,867 additional Series B Public Warrants, which amounts are included in the amounts, discussed above,
issued at closing of the November 2024 Registered Offering.

On November 13, 2024, the
Company closed a non-brokered private placement (the “November 2024 Private Offering”), pursuant to binding subscription
agreements with certain accredited investors as part of a non-brokered private placement of 2,199,602 units of the Company (the
“November 2024 Units”). Each November 2024 Unit consists of one Common Share, one Warrant (collectively, the “Series
A Private Warrants”) to purchase one Common Share and one-half of one Warrant to purchase one-half of one Common Share (collectively,
the “Series B Private Warrants” and, together with the Series A Private Warrants, the “November Private Warrants”).
Each November 2024 Unit was issued and sold at a price of $1.57. The gross proceeds of the November 2024 Private Offering were
approximately $3,500 before deducting offering expenses. Certain directors and officers of the Company (the “Insider Investors”)
purchased November 2024 Units at a price of $1.7675 per November 2024 Unit, which price includes $0.1975 per November 2024 Unit
and allowed such directors and officers to participate in the November 2024 Private Offering in accordance with the rules of the
Nasdaq Stock Market LLC (the “Nasdaq”). The Series A Private Warrants have an exercise price of $1.75 per underlying
Common Share, are exercisable immediately, and will expire on November 13, 2026. The Series B Private Warrants have an exercise
price of $2.07 per underlying Common Share, are exercisable beginning six months and one day from the date of issuance and will
expire on November 13, 2029. The Company recorded a non-cash expense of $34 and $110 to other operating expense and employee related
costs, respectively, representing the excess of fair value of the November 2024 Units over the purchase price paid by Insider Investors.

Based upon the
Company’s analysis of the criteria contained in ASC 815, the Company determined that the November Private Warrants met
the definition of a derivative liability, as any warrant exercise that could cause the holder to exceed 19.9% ownership of
NioCorp Common Shares would require shareholder approval. As such, the November Private Warrants were recognized as warrant
liabilities on the consolidated balance sheet and were measured at their issuance date fair value of
$1,928 and subsequently remeasured at each reporting period with changes being recorded as a non-operating gain or loss in the
consolidated statement of operations and comprehensive loss. The remaining proceeds of the November 2024 Private Offering of
$1,573 were allocated to Common Shares. The Company incurred total transaction costs related to the November 2024 Private Offering
of $161, of
which $60 was
allocated to the November Private Warrants and was expensed at closing.

(expressed in thousands of

“GXII Warrants”), as amended by an assignment, assumption and amendment agreement
(the “NioCorp Assumed Warrant Agreement”), and issued an aggregate of 15,666,626 Warrants (the “NioCorp Assumed
Warrants”). The Company 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 GX Sponsor II LLC (the “Sponsor”).

Each Private 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 Private 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 Private Warrant.

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

*Contingent Consent Warrants*

As consideration for entering
into the previously publicly disclosed Waiver and Consent Agreement, dated September 25, 2022 (the “Lind Consent”),
between the Company and Lind Global Asset Management III, LLC (“Lind III”), Lind III received, amongst other things,
the right to receive additional Warrants (the “Contingent Consent Warrants”) if on September 17, 2024, the closing
trading price of the Common Shares on the Toronto Stock Exchange or such other stock exchange on which such shares may then be
listed, is less than C$10.00, 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 U.S. dollar exchange rate as reported by Bloomberg, L.P.)
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
III that are exercised, if any, prior to the issuance of any Contingent Consent Warrants.

**Qualified
Person**

All
technical and scientific information that forms the basis for the Elk Creek Project disclosure included in this Quarterly Report
on Form 10-Q has been reviewed and approved by Scott Honan, M.Sc., SME-RM, NioCorp’s Chief Operating Officer. Mr. Honan
is a “Qualified Person” as such term is defined in National Instrument 43-101 – Standards of Disclosure for
Mineral Projects and subpart 1300 of Regulation S-K.

**Company
Overview**

NioCorp
is developing the Elk Creek Project, located in southeast Nebraska. The Elk Creek Project is a development-stage property that
has disclosed niobium, scandium, and titanium reserves and resources and disclosed rare earth mineral resources. The Company is
continuing technical and economic studies around the rare earths contained in the Elk Creek Project’s mineral resources
in order to determine whether extraction of rare earth elements can be reasonably justified and economically viable after taking
into account all relevant factors. Niobium has developing applications in the formulation of solid-state lithium-ion batteries,
which may reduce charging times and increase battery safety. 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 increases strength and/or
reduces weight, which can result in environmental benefits, including reduced fuel consumption and material usage and fewer air
emissions. Scandium can be combined with aluminum to make 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. Rare earths are critical to electrification and decarbonization initiatives and can
be used to manufacture the strongest permanent magnets commercially available.

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 mine
development and construction of the Elk Creek Project.

**Recent
Corporate Events**

On January 31, 2025, the Company closed an underwritten registered direct offering (the “January 2025 Offering”), pursuant to the underwriting agreement, dated January 29, 2025 (the January 2025 Underwriting Agreement”), with Maxim Group LLC, as underwriter, pursuant to which the Company issued and sold 2,577,320 Common Shares, 2,577,320 Series A warrants to purchase up to 2,577,320 Common Shares (the “January 2025 Series A Warrants”) and 1,288,660 Series B warrants to purchase up to an additional 1,288,660 Common Shares (the “January 2025 Series B Warrants”). Each Common Share was sold together with one Series A Warrant and one-half of one Series B Warrant at a combined public offering price of $1.94. The gross proceeds from the January 2025 Offering were approximately $5.0 million before deducting underwriting discounts and offering expenses. The January 2025 Series A Warrants have an exercise price of $1.98 per underlying Common Share, are exercisable immediately, and will expire on August 2, 2027. The January 2025 Series B Warrants have an exercise price of $2.05 per underlying Common Share, are exercisable immediately, and will expire on January 31, 2029.

**Elk
Creek Project Update**

On
October 30, 2024, the Company announced that it had completed bench-scale testwork at 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”) that successfully demonstrated that the process developed for extracting and recovering rare earth oxides found
in the ore at the Elk Creek Project can be used to recycle the rare earth content in rare earth permanent magnets. The L3 team
was able to demagnetize and grind up permanent rare earth magnets and then leach the contained rare earth elements from the magnet.
The successful outcome of this testing opens up the possibility

 21

of accepting mixed rare earth concentrate from other mines into
the planned Elk Creek plant once it is constructed and operating to supplement the ore expected to be produced from the Elk Creek
mine.

During
the quarter ended December 31, 2024, the Company completed negotiations with four landowners in Nebraska and entered into contract
amendments which extended the option periods by approximately five years for each Option to Purchase agreement (“OPT”)
covering four parcels of land for project construction and operation which the Company does not already own. The Company paid
$106,000 upon closing of the OPT extensions and will make periodic payments totaling $184,000 over the extension period.

Other
Activities

If
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 niobium, scandium, and titanium from the  Elk Creek Project, including the potential sale of titanium as titanium tetrachloride, as well as potential rare earth element  production;
- 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 Elk Creek Project site;
- Initiation  of revised mine groundwater investigation and control activities;
- Initiation  of long-lead equipment procurement activities;
- As  a follow-on to the Demonstration Plant operations, complete characterization and testing of waste materials to support tailings  impoundment and paste backfill plant designs;
- Continue  the engineering and costing of road improvements near the junction of Nebraska state highways 50 and 62, which are intended  to facilitate access to the Elk Creek Project site and manage increased traffic in the project vicinity; and
- Continue technical work with respect to improvements in the mine and the metallurgical process and costs.

**Financial

**Three-
and six-month periods ended December 31, 2024 compared to the three- and six-month periods ended December 31, 2023**

Significant
items affecting operating expenses are noted below:

*Employee-related
costs* increased for the three- and six-month periods in 2024 as compared to 2023, primarily due to the timing of fully vested
incentive options to purchase Common Shares (“Options”) issued to employees in 2024.

*Professional
fees* decreased for the three-month period in 2024 primarily due to increased audit fees associated with the
Company’s June 30, 2023 financial statements and increased review fees in connection with the Company’s September
30, 2023 financial statements, partially offset by transactions expenses (primarily legal and accounting costs) associated
with the warrant liabilities incurred with the November Offerings. Professional fees decreased for the six-month period in
2024 as compared to 2023, primarily due to higher costs incurred in 2023 related to the timing of legal services associated
with the Company’s SEC registration statements filed in October 2023, as well as increased audit fees associated with
the Company’s June 30, 2023 financial statements and increased review fees in connection with the Company’s
September 30, 2023 financial statements.

*Exploration
expenditures* decreased for the three- and six-month period in 2024 as compared to 2023, as 2023 costs included Demonstration
Plant operation costs. Operation of the Demonstration Plant ended during the prior year.

*Other
operating expenses* include costs related to investor relations, general office expenditures, equity offering and proxy expenditures,
board-related expenditures, and other miscellaneous costs. These costs increased for the three-month period in 2024 as compared
to 2023 primarily due to the timing of fully vested Options issued to board members and advisors in 2024 as well as broker fees
and other financial service costs associated with the warrant liabilities incurred with the November Offerings. These costs decreased
for the six-month period in 2024 as compared to 2023 primarily due to a decrease in director and officer insurance expense, as
well as declines in scandium development initiatives and financial-related services, partially offset by the timing of fully vested
Options issued to board members and advisors in 2024 and an increase in investor relation services.

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 changes in fair value related to the shares of Class B common stock
of Elk Creek Resource Corporation (“ECRC”), an indirect, majority-owned subsidiary of NioCorp formerly known as GX
Acquisition Corp. II, the rights of the holders of which to exchange such shares into Common

 23

Shares are subject to certain vesting
conditions (such shares of ECRC Class B common stock, the “Earnout Shares”). The credit balances for all periods represents
the impact of decreases in the Company’s Common Share price on the financial modeling used to determine the period end fair
values.

*Change
in fair value of warrant liabilities* represents the changes in fair value of Common Share purchase warrants (“Warrants”)
that are carried as liabilities in the condensed consolidated balance sheet. Expenses for the three- and six-month periods ending
December 31, 2023, primarily related to Lind Global Asset Management III, LLC’s (“Lind III”) right to receive
additional warrants (the “Contingent Consent Warrants”) as consideration for entering into the previously disclosed
Waiver and Consent Agreement, dated September 25, 2022 (the “Lind Consent”), between the Company and Lind III. Expense
was recorded in these periods based on the impact of a lower closing Common Share price, which increased the probability of these
Contingent Consent Warrants being issued on the 18-month anniversary. The credit amounts booked for the three-and six-month periods
ending December 31, 2024, primarily related to the impact of our declining Common Share market price on the Black-Scholes modeling
results for our outstanding warrant liabilities.

*Interest
expense* decreased for the three-and six-month periods in 2024 as compared to 2023 as 2023 periods included accretion expense
associated with the unsecured convertible debentures (the “Convertible Debentures”) issued to Yorkville in March 2023.
The outstanding balance of the Convertible Debentures was substantially reduced during fiscal year 2023, and was fully retired
in the first quarter of 2024, resulting in lower accretion during 2024.

*Other
Gain*s for the six-month period ended December 31, 2024, primarily relates to a non-cash gain on the issuance of the Contingent
Consent Warrants, which were issued in September 2024.

*Loss
attributable to noncontrolling interest* represents the portion of net loss in ECRC not owned by the Company.

**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 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.

On
April 12, 2024, the Company issued and sold to Yorkville and Lind Global Fund II LP (“Lind II” and, together with
Yorkville, the “April 2024 Purchasers”), pursuant to a securities purchase agreement, dated April 11, 2024 (the “April
2024 Purchase Agreement”), between the Company and each of the April 2024 Purchasers. The Company also issued to the April
2024 Purchasers, in proportion to the aggregate principal amount of the April 2024 Notes issued to each April 2024 Purchaser,
Warrants to purchase up to 615,385 Common Shares (the “April 2024 Warrants”), which are equal to 25% of the aggregate
principal amount of April 2024 Notes issued to the April 2024 Purchasers divided by the exercise price of $3.25, subject to any
adjustment to give effect to any stock dividend, stock split or recapitalization.

On
November 5, 2024, the Company closed the November 2024 Registered Offering, pursuant to the underwriting agreement, dated November
3, 2024 (the “Underwriting Agreement”), with Maxim Group LLC, as underwriter (the “Underwriter”), which
consisted of 1,592,356 Common Shares, 1,672,090 Warrants (the “Series A Public Warrants”) to purchase up to an additional
1,672,090 Common Shares and 836,045 Warrants (the “Series B Public Warrants” and, together with the Series A Public
Warrants, the “November Public Warrants”) to purchase up to an additional 836,045 Common Shares. Each Common Share
was sold together with one Series A Public Warrant and one-half of one Series B Public Warrant at a combined public offering price
of $1.57. The gross proceeds from the November 2024 Registered Offering were approximately $2.5 million before deducting underwriting
discounts and offering expenses. The Company entered into a warrant agency agreement with Computershare Inc. and its affiliate,
Computershare Trust Company, N.A., together as warrant agent, setting forth the terms and conditions of the November Public Warrants.
The Series A Public Warrants have an exercise price of $1.75 per underlying Common Share, are exercisable immediately, and will
expire on November 5, 2026. The Series B Public Warrants have an exercise price of $2.07 per underlying Common Share, are exercisable
beginning six months and one day from the date of issuance, and will expire on November 5, 2029. In addition, pursuant to the
Underwriting Agreement, the Company granted the Underwriter a 45-day over-allotment option to purchase (i) 238,853 additional
Common Shares and (ii) 358,280 Option Warrants (as defined below) to purchase up to an aggregate of 358,280 Common Shares. “Option
Warrant” means one Series A Public Warrant combined with one-half

 24

of one Series B Public Warrant. On November 4, 2024, Underwriter
partially exercised its over-allotment option to purchase 79,734 additional Series A Public Warrants and 39,867 additional Series
B Public Warrants, which amounts are included in the amounts issued at closing of the November 2024 Registered Offering above.

On November 13, 2024, the Company
closed a non-brokered private placement (the “November 2024 Private Offering” and, together with the November 2024
Registered Offering, the “November Offerings”) pursuant to binding subscription agreements with certain accredited
investors (the “Private Placement Investors”) as part of a non-brokered private placement of 2,199,602 units of the
Company (the “November 2024 Units”). Each November 2024 Unit consists of one Common Share, one Warrant (the “Series
A Private Warrants”) to purchase up to an additional Common Share and one-half of one Warrant to purchase up to an additional
one-half of one Common Share (the “Series B Private Warrants” and, together with the Series A Private Warrants, the
“November Private Warrants”). Each November 2024 Unit was issued and sold at a price of $1.57. The gross proceeds of
the November 2024 Private Offering were approximately $3.5 million before deducting offering expenses. Certain directors and officers
of the Company purchased November 2024 Units at a price of $1.7675 per November 2024 Unit, which price includes $0.1975 per November
2024 Private Unit and allows such directors and officers to participate in the November 2024 Private Offering in accordance with
the rules of the Nasdaq. The Series A Private Warrants have an exercise price of $1.75 per underlying Common Share, are exercisable
immediately, and will expire on November 13, 2026. The Series B Private Warrants have an exercise price of $2.07 per underlying
Common Share, are exercisable beginning six months and one day from the date of issuance, and will expire on November 13, 2029.

The November Offerings and the sale of
the April 2024 Notes have provided, and the January 2025 Offering and the Yorkville Equity Facility Financing Agreement are 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. In the near term, the Company intends to utilize the Yorkville Equity
Facility Financing Agreement for working capital and general corporate purposes, including to advance our efforts to launch construction
of the Elk Creek Project and move it to commercial operations. The Company may also 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.

On
September 11, 2024, the Company and Mark Smith entered into the Smith Loan Agreement, which provides for a $2.0 million non-revolving
credit facility (the “Smith Loan”). A total of $504,000 was subsequently drawn down, and subsequently the Company
repaid $508,000, representing the balance of the interest and principal outstanding under the Smith Loan, plus $41,000 related
to the loan origination fees payable.

As
of December 31, 2024, the Company had cash of $0.5 million and a working capital deficit of $3.1 million, compared to cash of
$2.0 million and a working capital deficit of $9.0 million on June 30, 2024.

We expect that the Company will
operate at a loss for the foreseeable future. The Company’s current planned cash needs are approximately $13.0 million
until June 30, 2025. On September 4, 2024, NioCorp entered into (i) a consent and waiver (the “September Yorkville
Consent”) to the April 2024 Notes issued and sold to Yorkville pursuant to the April 2024 Purchase Agreement and (ii) a
consent and waiver (together with the Yorkville Consent, the “September Consents”) to the April 2024 Notes issued
and sold to Lind II. On October 3, 2024, NioCorp entered into (i) a consent and waiver (the “October Yorkville
Consent”) to the April 2024 Notes issued and sold to Yorkville pursuant to the April 2024 Purchase Agreement and (ii) a
consent and waiver (together with the September Consents and the October Yorkville Consent, the “2024 Note
Consents”) to the April 2024 Notes issued and sold to Lind II pursuant to the April 2024 Purchase Agreement. The 2024
Note Consents, among other things, extended and deferred certain monthly payments and extended the maturity of the April 2024
Notes until January 31, 2025. On January 3, 2025, NioCorp entered into a consent and waiver (the “January Yorkville
Consent”) to the April 2024 Notes issued and sold to Yorkville pursuant to the April 2024 Purchase Agreement. The
January Yorkville Consent, among other things, deferred the due date for the amounts that would otherwise have been due to
Yorkville on January 1, 2025 to the maturity date and extended the maturity date to February 17, 2025, and
prospectively waived any term of the April 2024 Notes that would otherwise be triggered upon a failure of the Company to pay
to Yorkville the remainder of the amount due on January 1, 2025. See Notes 6b and 13 to the interim condensed consolidated
financial statements for additional information on the terms of the 2024 Note Consents and January Yorkville Consent,
respectively. All remaining amounts due to Lind II ($176,000) and Yorkville ($1.0 million) under the April 2024 Notes were repaid on
January 6, 2025, And February 7, 2025, respectively.

In
addition to outstanding accounts payable and short-term liabilities, our average monthly planned expenditures through June 30,
2025, are expected to be approximately $2.275 million per month where approximately $0.350 million is for corporate overhead and
estimated costs related to securing financing necessary for advancement of the Elk Creek Project. This

 25

includes general overhead costs and satisfying outstanding accounts payable. This also includes anticipated
financing costs associated with the Elk Creek Project. The scope of these financing costs remains under discussion with EXIM. Approximately
$1.925 million per month is planned for expenditures relating to the advancement of the Elk Creek Project by NioCorp’s majority
owned subsidiary, ECRC, including an updated mine plan in connection with the EXIM application process. 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 $12.0
million to $15.0 million, net of funds raised from advances under the Yorkville Equity Facility Financing Agreement and borrowings
under the Smith Loan, if any, are likely to be necessary to continue advancing the Elk Creek 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 will likely require additional capital to meet its cash needs. 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.

Current Elk Creek property lease commitments
are $136,000 through June 30, 2025. 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, 2025, 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 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 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. The Company was informed that its application received approval by the first of three reviews by the EXIM Transaction
Review Committee (the “TRC”) on October 2, 2023. During the quarter, EXIM continued to process the Company’s
application for debt financing under EXIM’s Make More in America Program. The Company’s application sits at TRC in
the second step in EXIM’s four-step approval process. The Company continues to meet with EXIM as well as providing responses
to requests for additional information from EXIM and to the consultants that are conducting due diligence on the Company’s
application on behalf of EXIM. As part of the diligence process, EXIM has identified additional project activities to be undertaken,
including, among other things, an updated mine plan and updated Elk Creek Project capital costs on a final or close-to-final basis
reflecting updated process flows. However, there can be no assurance what further project activities or matters EXIM may request
in connection with the application process.

We
are currently unable to estimate how long the application process may take, and there can be no assurances that we will be able
to successfully negotiate a final commitment of debt financing from EXIM.

Except for the potential funding from advances under the Yorkville Equity Facility Financing Agreement,
as 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, dated as of March 17, 2023 (as amended, supplemented or otherwise
modified, the “Exchange Agreement”), by and among NioCorp, ECRC and the Sponsor, 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 January 2025 Underwriting Agreement also contains certain covenants
that, among other things, limit NioCorp’s ability 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, at-the-market agreement
or other continuous offering of Common Shares, subject to certain exceptions. Notwithstanding the restrictions set forth in the
Exchange Agreement and the January 2025 Underwriting 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 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

 26

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, as supported by the notes that accompany our financial statements
for the year ended June 30, 2024, that substantial doubt exists as to our ability to continue as a going concern. The interim
condensed consolidated financial statements included in this Quarterly Report on Form 10-Q 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, 2024, to fund
normal operations and meet debt obligations for the next twelve months without deferring payment on certain current liabilities
and raising additional funds. Uncertainty in capital markets, supply chain disruptions, increased interest rates and inflation,
and the potential for geographic recessions have contributed to general global economic uncertainty. During the three months ended
December 31, 2024, 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 six months ended December 31, 2024, the Company’s operating activities consumed $2.0 million of cash (2023: $4.6 million).
The cash used in operating activities for the six months ended December 31, 2024, reflects the Company’s funding of losses
of $2.6 million, increased fair value related to the Earnout Shares and Warrant liabilities, share-based compensation, and other
non-cash transactions. Overall, operational outflows during the six months ended December 31, 2024, decreased from the corresponding
period of 2023 due to costs and expenditures incurred in connection with the Company’s Demonstration Plant. Going forward,
the Company’s working capital requirements are expected to increase substantially in connection with the development of
the Elk Creek Project.

**Financing
Activities**

Financing
inflows were $0.5 million during the three months ended December 31, 2024 (2023 inflows: $2.9 million), with 2024 inflows reflecting
the gross receipts of $6.0 million from the November Offerings and $1.8 million from Common Share issuances under the Yorkville
Equity Facility Financing Agreement, offset by $6.0 million of convertible debt repayments and $1.3 million of share issuance
costs.

**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 Exchange Agreement and the January
2025 Underwriting 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.

 27

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.

**Critical
Accounting Estimates**

There
have been no material changes in our critical accounting estimates discussed in “Management’s Discussion and Analysis
of Financial Condition and Results of Operations” under the heading “Critical Accounting Estimates and Recent Accounting
Pronouncements” as of June 30, 2024, in the Annual Report on Form 10-K.

**Certain
U.S. Federal Income Tax Considerations**

If
NioCorp (or a subsidiary) is a 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 NioCorp securities (as determined under applicable U.S. federal income tax law), then certain
significant adverse tax consequences could apply to such U.S. holder, including requirements to treat any gain realized upon a
disposition of Common Shares (or other securities) as ordinary income, to include certain “excess distributions” on
Common Shares in income, and to pay an interest charge on a portion of any such gain or distribution. NioCorp believes that it
was classified as a PFIC during the taxable years ended June 30, 2024 and 2023, and, based on the current composition of its income
and assets, as well as current business plans and financial expectations, that it may be classified as a PFIC for its current
taxable year or in future taxable years. No opinion of legal counsel or ruling from the Internal Revenue Service (the “IRS”)
concerning the PFIC status of NioCorp or any subsidiary has been obtained or is currently planned to be requested. The determination
of whether any corporation was, or will be, a PFIC for a taxable year depends, in part, on the application of complex U.S. federal
income tax rules, which are subject to differing interpretations. In addition, whether any corporation will be a PFIC for any
taxable year depends on the assets and income of such corporation over the course of each such taxable year and, as a result,
cannot be predicted with certainty as of the date of this Quarterly Report on Form 10-Q. In addition, even if NioCorp concluded
that it or any subsidiary was not classified as a PFIC, the IRS could challenge such determination and a court could sustain the
challenge. Accordingly, there can be no assurance that NioCorp or any subsidiary will not be classified as a PFIC for any taxable
year. Each holder of Common Shares or other NioCorp securities should consult its own tax advisors regarding the PFIC status of
NioCorp and each subsidiary thereof and the resulting tax consequences to the holder, as well as any potential to mitigate such
tax consequences through a “QEF” or “mark-to-market” election. See the “Risk Factors” section
of the Annual Report on Form 10-K.

**ITEM
3. 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. dollars and Canadian dollars. Canadian dollar expenditures are primarily related to certain
Common Share-related costs and corporate 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.

**ITEM
4. CONTROLS AND PROCEDURES**

**Disclosure
Controls and Procedures**

The
management of NioCorp Developments Ltd. has evaluated, under the supervision of and with the participation of our management,
including the Chief Executive Office (“CEO”) and the Chief Financial Officer (“CFO”), the effectiveness
of the design and operations of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act) as of December 31, 2024. Based on that evaluation, the CEO and the CFO have concluded that, as of December 31, 2024,
our disclosure controls and procedures were not effective due to the material weaknesses in internal control over financial reporting
described below.

Notwithstanding the material weaknesses
in our internal control over financial reporting, our CEO and CFO have concluded that the interim condensed consolidated financial
statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results
of operations and cash flows for the periods presented in conformity with U.S. GAAP.

***Material Weaknesses in Internal Control
over Financial Reporting Existing as of December 31, 2024***

The management of NioCorp Developments
Ltd. is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f)
and 15d-15(f) of the Exchange Act for the Company. Management assessed the effectiveness of our internal control over financial
reporting as of December 31, 2024. 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 December 31, 2024, our internal control over financial
reporting was not effective due to the material weaknesses in internal control over financial reporting described below.

 29

*Material
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 our annual or interim consolidated financial statements will not be
prevented or detected on a timely basis.

Management
concluded that the material weaknesses disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended June
30, 2024, continued to exist as of December 31, 2024. Specifically, management identified deficiencies in the principles associated
with the control environment, risk assessment, control activities, and monitoring components of internal control, based on the
criteria established by the COSO Framework, that constitute material weaknesses, either individually or in the aggregate.

- Control  Environment: 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 financing  transactions and associated reporting requirements. This material weakness contributed  to additional material weaknesses further described below.
- Risk  Assessment: The Company does not have a formal process to identify, update, and assess  financial reporting 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 maintain effective controls over:

○ monitoring  and assessing the work of third-party specialists, including the evaluation of the appropriateness  of accounting conclusions, and

○ the  evaluation of certain inputs and assumptions used to estimate the fair value of instruments  and features associated with complex debt and equity transactions.

- Monitoring  Activities: Management did not appropriately:

○ select,  develop, and perform ongoing evaluation to ascertain whether the components of internal  controls are present and functioning, and

○ evaluate  and communicate internal control deficiencies in a timely manner to those parties responsible  for taking corrective action.

As
previously disclosed, these material weaknesses resulted in errors that required the restatement of 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, March
31, 2022, September 30, 2022, and December 31, 2022. 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 Weaknesses***

To
address our material weaknesses existing as of December 31, 2024, we have implemented a detailed plan to address each individual
material weakness identified, including the following:

- We  have, and will continue, to engage outside accounting and internal control consultants  with subject matter expertise to supplement our level of knowledge, experience, and training  in accounting and internal control over financial reporting.
- We  plan to develop a formal risk assessment process to ensure that it is robust and frequent  enough for the Company’s business, including the identification of risks, the level  of detail in our risk assessment, and the clarity of the linkage between risks and internal  controls associated with the material weaknesses. The results of this effort are expected  to enable us to effectively identify, develop, evolve and implement controls and procedures  to address risks.
- We  plan to develop and provide incremental training to the accounting and financial reporting  team regarding accounting for and valuation of complex financial instruments.
- Management  will develop a monitoring program to periodically evaluate and assess whether those responsible  for controls are conducting their activities in accordance with their design, such that  there is contemporaneous evidence

30

that the controls are present and functioning and will  communicate internal control deficiencies in a timely manner to those parties responsible  for taking corrective action.

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 December
31, 2024, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

4. MINE SAFETY DISCLOSURES**

Pursuant
to Section 1503(a) of 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 United States 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 three-month period ended December 31, 2024, 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.
