1. NATURE OF OPERATIONS

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

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

   First Mining is advancing a portfolio of gold projects in Canada, with the most advanced projects being the Springpole Gold Project in northwestern Ontario and the Duparquet Gold Project in the Abitibi region of Québec. In addition, the Company holds a 30% interest in PC Gold Inc., the legal entity which holds the Pickle Crow gold project which is being advanced by FireFly Metals Ltd. ("FireFly Metals").

   The Company's annual consolidated financial statements ("financial statements") have been prepared on a going concern basis, which contemplates that the Company will be able to continue its operations for at least twelve months from December 31, 2025 and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Company has not generated revenue from operations to date and may require additional financing or outside participation to undertake further advanced exploration of its mineral properties.

3. MATERIAL AND OTHER ACCOUNTING POLICIES

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

   1. Financial Instruments
      1. Classification

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

      2. Measurement

         Financial assets at FVTOCI

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

         Financial assets and liabilities at amortized cost

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

         Financial assets and liabilities at FVTPL

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

      3. Impairment of financial assets at amortized cost

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

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

         3. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)
      4. Derecognition

         Financial assets

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

         Financial liabilities

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

   2. Cash and Cash Equivalents

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

   3. Assets Held for Sale

      The Company has accounted for assets held for sale in accordance with IFRS 5 Non-current assets held for sale and discontinued operations. Items classified as assets held for sale are non-current assets and liabilities that will be recovered principally through a sale transaction rather than continual use. This condition is satisfied when the asset is available for immediate sale in its present condition, management is committed to the sale, and it is highly probable to occur within a 12-month period. Non-current assets (and disposal groups) classified as held for sale are measured at the lower of their previous carrying amount and fair value less selling costs and, if significant, are presented separately from other assets as current assets, with liabilities associated with assets held for sale presented separately as current liabilities, in the consolidated statements of financial position.

   4. Mineral Properties

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

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

      3. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)

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

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

   5. Impairment of Non-Financial Assets

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

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

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

      • The right to explore the area has expired or will expire in the near future with no expectation of renewal;

      • Substantive expenditure on further exploration for and evaluation of mineral resources in the area is neither planned nor budgeted;

      • No commercially viable deposits have been discovered, and the decision had been made to discontinue exploration in the area; and

      • Sufficient work has been performed to indicate that the carrying amount of the expenditure carried as an asset will not be fully recovered.

   6. Property and Equipment

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

      3. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)

      Depreciation is recognized in profit or loss on a straight-line basis over the following estimated useful lives: Buildings 10 years

      Machinery and equipment 5 years

      Furniture and fixtures 5 years

      Vehicles 5 years

      Computer equipment 3 years

      Computer software 1 year

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

   7. Environmental Reclamation Provision

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

      The nature of the reclamation activities includes restoration and revegetation of the affected exploration sites.

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

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

   8. Income Taxes

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

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

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

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

1. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)
   1. Share Capital

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

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

Consideration received from financings involving units consisting of common shares and warrants is allocated to the share capital and the warrant reserve accounts using the relative fair value method. As prescribed by this method, the consideration is allocated to the value of share capital and warrant reserve on a pro rata basis.

1. Loss per Share

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

2. Share-based Payments

   Stock options

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

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

   Performance share units

   The fair value of performance share units ("PSUs") is measured using a Monte Carlo simulation model, based upon several assumptions, including share price volatility, the Company's share performance and the Company's share performance in relation to its peers (See Note 12(g)). The cost is recorded over the vesting period within equity until settled.

   3. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)

   Deferred share units and restricted share units

   Deferred share units ("DSUs") and restricted share units ("RSUs") are measured based on the fair value at the grant date. The cost is recorded over the vesting period within equity until settled. Equity-settled awards are not remeasured subsequent to the initial grant date.

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

3. Leases

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

4. Segment Reporting

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

5. Investments in associates

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

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

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

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

   At the end of each reporting period, the Company assesses whether there is any objective evidence that an investment in an associate is impaired. Objective evidence includes observable data indicating there is a measurable decrease in the estimated future cash flows of the investee's operations. A significant or prolonged decline in the fair value of an equity investment below its cost is objective evidence of impairment. When there is objective evidence that an investment is impaired, the carrying amount of such investment is compared to its recoverable amount, being the higher of its fair value less costs of disposal and value-in-use.

   3. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)

   If the recoverable amount of an investment is less than its carrying amount, the carrying amount is reduced to its recoverable amount and an impairment loss is recognized in the period in which the relevant circumstances are identified. When an impairment loss reverses in a subsequent period, the carrying amount of the investment is increased to the revised estimate of recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had an impairment loss not been previously recognized. A reversal of an impairment loss is recognized in net income in the period in which the reversal occurs.

6. Accounting Policy Judgements and Estimation Uncertainty

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

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

   1. Accounting Policy Judgements Mineral Property Impairment Indicators

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

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

   2. Accounting Policy Judgement and Estimate Uncertainty Impairment assessments for Investments in Associates

      The Company is required to make estimates and judgments about future events and circumstances and whether the carrying amount of the asset exceeds its recoverable amount. Recoverability depends on various factors, including the identification of economic recoverability of reserves at each associate's exploration properties, the ability of each associate to obtain the necessary financing to complete the development, and future profitable production or proceeds from the disposition. The publicly quoted share price of an associate, where applicable is a source of objective evidence about the recoverable amount.

      Management determined that the change of control of the JV partner was an indicator of impairment, The recoverable amount was estimated using the fair value less cost of disposal benchmark implied by the February 2026 Bellavista transaction (note 20). Level 3 classification applied due to probability-weighted performance rights (note 8).

      3. MATERIAL AND OTHER ACCOUNTING POLICIES (continued) Fair Value Investment - PC Gold

      The Fair value less cost to disposal for the PC Gold investment incorporates unobservable inputs, including probability assessments for performance rights milestones and expected achievement timing. A possible change of

      ±10% in the Milestone 2 probability would result in a ±$0.5 million change in fair value, which is approximately 2% of the carrying amount. Management expects no material adjustments are expected in the next 12 months (Note 8).

   3. Estimation Uncertainty Fair Value of Silver Stream Derivative Liability

      The determination of the fair value of the Silver Stream is an area of significant estimation uncertainty. The fair value is calculated by utilising a Monte Carlo simulation valuation model. A Monte Carlo valuation model relies on random sampling and is often used when modeling cash flows with many inputs and where there is significant uncertainty in the future value of inputs and where the movement of the inputs can be independent of each other (see Note 18). The key inputs used in the Silver Stream fair value calculation are further disclosed in Note 9. Changes in the inputs to the valuation model may result in material changes in the fair value of the silver stream derivative liability and the amount of fair value gains or losses recognized in profit or loss in future periods.

      Fair Value of the Option - PC Gold

      The Company has made assumptions when estimating the fair value of the PC Gold option liability which arises under the terms of the Earn-In Agreement described in Note 8. As there is no observable market data which can be used to determine the fair value of the Option - PC Gold liability, management uses property specific and market-based information to determine whether a significant change in the fair value of the option liability has occurred. The specific assumptions made are disclosed in Note 8. Changes in these assumptions can significantly affect the fair value estimate.

      Impairment assessments for assets held for sale

      The value of assets held for sale requires significant judgement. Illiquid markets, commodity prices, and uncertain selling costs contribute to potential variance in the final value received by the Company. The reported carrying value is assessed each reporting period (Note 4).

7. IFRS Accounting Standards and Interpretations Issued but Not Yet Effective

Certain new accounting standards and interpretations have been published that are either applicable in the current year or not mandatory for the current period. The Company has assessed these standards, including Amendments to IAS 1 - Non-current Liabilities with Covenants, and determined they do not have a material impact on the Company's consolidated financial statement, except for potential changes in presentation and disclosure.

The following standards have been issued by the International Accounting Standards Board ("IASB") and are not yet effective for the Company.

• Amendments to the Classification and Measurement of Financial Instruments (IFRS 9 and IFRS 7) (effective for annual reporting periods beginning on or after January 1, 2026):

The Company has assessed these amendments and does not expect a material impact on its consolidated financial statements.

1. MATERIAL AND OTHER ACCOUNTING POLICIES (continued)

   • IFRS 18 Presentation and Disclosure in Financial Statements (effective for annual reporting periods beginning on or after January 1, 2027):

     The Company is currently assessing the impact of IFRS 18. IFRS 18 is expected to primarily impact presentation and disclosure, including changes to required subtotals and disaggregation in the statement of profit or loss, and is not expected to impact recognition and measurement.

     No standards have been early adopted in the current period, and are not expected to have a material impact on the Company's consolidated financial statements.

2. ASSETS HELD FOR SALE

   On November 20, 2025, the Company announced it entered into a definitive amalgamation agreement to sell its wholly-owned subsidiary, Cameron Gold Operations ("Cameron Gold"), which owns the Cameron Gold Project to Oronova Energy Inc. ("Oronova") for total estimated consideration of $27.0 million comprised of $5.0 million in cash, 80,000,000 common shares of Oronova at a deemed value of $0.25 per share and a future cash payment of at least

   $2.0 million in cash that will be made upon the processing of a stockpile at Cameron pursuant to a stockpile agreement. Accordingly, as of December 31, 2025, the Company reclassified $27.0 million from mineral properties to assets held for sale (Note 7). The assets reclassified as assets held for sale are measured at the lower of carrying amount and fair value less costs to sell. As a result, a non-cash impairment loss of $6.4 million was recognized in the Statements of Net Loss and Comprehensive Loss. The disposal did not meet the criteria to be presented as a discontinued operation. The transaction closed on March 10, 2026 (Note 20).

1. MINERAL PROPERTIES (continued)

   The Company has various underlying agreements and commitments with respect to its mineral properties, which define annual or future payments in connection with royalty buy-backs or maintenance of property interests, the most significant of which are discussed below.

   1. Duparquet Project

      As at December 31, 2025, the Company's provision for environmental remediation activities is $2,806,000 (December 31, 2024 - $3,035,000). The environmental remediation includes site preparation, construction of a storage area, construction of an access road, excavation and transportation of mining material, and site restoration and rehabilitation of the storage area. The Company has been working closely with the Ministry of Environment, the Fight Against Climate Change, Wildlife and Parks ("MELCCFP") and submitted a permit application to start work in 2025. During the year ended December 31, 2025, the Company incurred $2,365,000 of environmental remediation expenditures related to these activities. The environmental remediation estimate is based on the current scope of work and management's best estimate of the remaining costs required to complete the remediation activities. During the year ended December 31, 2025, the Company recorded an increase in estimated remediation costs of

      $2,136,000 (December 31, 2024 - $1,535,000). The final environmental remediation cost may vary depending on additional feedback received from MELCCFP and the execution of the work.

   2. Hope Brook Project

      First Mining owned a 20% interest in the Hope Brook Gold Project - a joint venture with Big Ridge who owned the remaining 80% interest and is the current operator. On July 31, 2025, the Company closed a transaction with Big Ridge to sell its remaining 20% project interest in the Hope Brook Project for total consideration comprised of $3 million in cash and 7 million common shares of Big Ridge. As a result, the Company recorded a gain of $1 million on the sale through profit and loss for the year ended December 31, 2025.

2. INVESTMENT IN PC GOLD INC.

As at December 31, 2025, the Company owns a 30% interest in PC Gold Inc. and maintains significant influence, which requires the investment to be accounted for using equity accounting. As at December 31, 2025, the carrying value of the investment in PC Gold Inc. was $21,524,000 (December 31, 2024 - $21,527,000). The subsequent equity accounting for PC Gold is based on audited results that are publicly available information for the year ended June 30, 2025, and on the unaudited financial information for the six-month period ended December 31, 2025.

As at December 31, 2025, the Company has recorded an option liability of $4,692,000 (December 31, 2024 -

$3,974,000), which represents the additional net dilution that would result from FireFly Metals completing its additional 10% equity interest in PC Gold Inc. Following receipt of $3,000,000 under this option, First Mining's ownership would reduce to 20%. The FireFly Metals Earn-In Agreement requires First Mining to contribute its prorata share of environmental reclamation funding, which was 30% as at December 31, 2025.

As at December 31, 2025, the Company has recorded a liability for reclamation funding of $151,000 (December 31, 2024 - $151,000), which is in line with FireFly Metals' estimate of the environmental reclamation provision.

On February 9, 2026, Firefly Metals Ltd. ("Firefly") announced the sale of its 70% interest in PC Gold Inc. to Bellavista Resources Limited ("Bellavista") for 60 million shares as upfront consideration upon completion of the Acquisition, together with 50 million performance rights as contingent consideration. In connection with this transaction, Bellavista has indicated its intention to exercise the PC Gold buydown right to increase their ownership to 80% of the Project by paying $3.0 million in cash, subject to completion of the transaction. Management performed an

   impairment assessment at December 31, 2025, and concluded no impairment was required as the estimated recoverable amount exceeded the carrying value of $21.5 million.

2. SILVER STREAM DERIVATIVE LIABILITY
   1. Silver Purchase Agreement Overview and Consideration Received

      On June 10, 2020, the Company entered into a silver purchase agreement (the "Silver Purchase Agreement") with First Majestic Silver Corp. ("First Majestic"), which closed on July 2, 2020. Under the terms of the Silver Purchase Agreement, First Majestic agreed to pay First Mining total consideration of US$22.5 million (approx. $30.6 million as at the closing date), in three tranches, for the right to purchase 50% of the payable silver produced from the Springpole Gold Project over the life of the project (the "Silver Stream") and received 30 million common share purchase warrants of First Mining (subsequently adjusted to 32 million common share purchase warrants in accordance with the terms of the Silver Purchase Agreement).

      Each share purchase warrant entitles First Majestic to purchase one common share of First Mining at an exercise price of $0.40 for a period of five years (subsequently re-priced to $0.374 in accordance with the terms of the Silver Purchase Agreement). The fair value of warrants is determined using Black-Scholes option pricing model.

      First Mining has the right to repurchase 50% of the Silver Stream for US$22.5 million (approximately C$30.8 million as at December 31, 2025) at any time prior to the commencement of production at Springpole Gold Project (the "Buy-Back Right"). A Monte Carlo simulation was performed to evaluate the buy-back option under the Silver Stream agreement.

      Per the Silver Purchase Agreement, First Majestic paid US$10 million ($13.7 million) to First Mining on the July 2, 2020, closing date, with US$2.5 million ($3.3 million) paid in cash and the remaining US$7.5 million ($10.4 million) paid in 805,698 common shares of First Majestic ("Tranche 1").

      Upon announcement of the Pre-Feasibility Study ("PFS") on March 4, 2021, First Mining received US$7.5 million ($9.8 million) from First Majestic, with US$3.75 million ($4.8 million) paid in cash and the remaining US$3.75 million ($5.0 million) paid in 287,300 common shares of First Majestic ("Tranche 2"). The final tranche ("Tranche 3") of US$5.0 million ($6.5 million) was to be payable by First Majestic upon First Mining receiving approval of a federal or provincial environmental assessment for the Springpole Gold Project, which was to be paid half in cash and half in shares of First Majestic. Please refer to the details of the amending agreement below.

      The Silver Stream has an initial term of 40 years from July 2, 2020. The term is automatically extended by successive 10-year periods as long as the life of mine continues for the Springpole Gold Project. If, upon expiration of the term of the Silver Purchase Agreement, the Company has not sold to First Majestic an amount of silver sufficient to reduce the Advance Payment to nil, then a refund of the uncredited balance, without interest will be due and owing by the Company to First Majestic. The silver delivered to First Majestic may be sourced from the Springpole Gold Project, or the Company may substitute any required refined silver with refined silver from a source other than the Springpole Gold Project, with the exception of silver purchased on a commodity exchange.

      On March 28, 2025, the Company received the final payment of US$5 million ($7.2 million) from First Majestic in connection with the Silver Stream. The parties entered into an amending agreement to the Silver Purchase Agreement on March 13, 2025 ("Amending Agreement") to amend the terms of the final payment due from First Majestic under the Silver Purchase Agreement (the "Tranche 3 Payment"). Under the Amending Agreement, the Tranche 3 payment would be made earlier than originally scheduled and would consist of US$5 million in cash, with no requirement for the completion of the environmental assessment.

      9. SILVER STREAM DERIVATIVE LIABILITY (continued)

      As consideration for amending the terms of the Tranche 3 payment, the Company has amended the terms of the common share purchase warrants (the "Warrants") that were issued to First Majestic on July 2, 2020 under the terms of the Silver Purchase Agreement. The 32,050,228 Warrants that were issued to First Majestic had an exercise price of $0.374 per Warrant and were set to expire on July 2, 2025. The Company revised the exercise price of the Warrants to $0.20 and extended the expiry date of the Warrants to March 31, 2028. As a result, the fair value of the Warrants, amounting to $1.3 million, was recognized in the statements of changes in equity, with the fair value determined using Black-Scholes option pricing model. All other terms of the Warrants remained unchanged. On December 16, 2025, the Company received total proceeds of approximately $6.4 million from First Majestic's exercise of 32,050,228 Warrants.

   2. Silver Stream Derivative Liability Fair Value

The Company has determined that the Silver Stream is a standalone derivative measured at FVTPL. The estimated fair value of the Silver Stream derivative liability is determined using a discounted cash flow model which incorporates a Monte Carlo simulation, with the following key input assumptions: 1) Observable assumptions including implied volatility of COMEX silver, COMEX silver future curve, silver spot price, USD risk-free rate, USD/CAD foreign exchange rates, and share price of the Company, and 2) Unobservable assumptions including the timing of commencement of production (2030 based on the updated prefeasibility study), estimated annual silver production volumes (averaging 1.47 million payable ounces a year over the life of mine based on the updated prefeasibility study), the Company's credit spread, and payable silver quantities.

The fair value of the Silver Stream derivative liability is classified within Level 3 of the fair value hierarchy because certain significant inputs are unobservable. The fair value is determined by a third party valuation expert using an independent Monte Carlo model reviewed quarterly by management. Unobservable inputs are updated based on recent comparable market data.

The estimated fair value is sensitive to changes in key assumptions, particularly silver spot prices, silver forward prices, foreign exchange rates, volatility assumptions, the Company's credit spread and payable silver quantities, and a change in any of these assumptions could result in a material change in the estimated fair value. Based on the valuation as at December 31, 2025, a 10% increase (decrease) in silver prices would result in an increase (decrease) in the fair value of the Silver Stream derivative liability of approximately $10.4 million. A 5% increase (decrease) in volatility would result in an increase (decrease) of approximately $0.7 million. A 10% increase (decrease) in estimated production volumes would result in an increase (decrease) of approximately $10.1 million. A 50 basis point increase (decrease) in the Company's credit spread would result in a decrease (increase) of approximately $3.9 million. These sensitivities are based on a change in one assumption while holding all other assumptions constant. In practice, changes in one or more assumptions may be correlated.

The fair value of the Silver Stream derivative liability is valued using a Monte-Carlo simulation, with gains or losses recorded in the statement of net loss and comprehensive loss. As at December 31, 2025, the fair value of the Silver Stream derivative liability is US$78,258,000 ($107,260,000). The fair value of the Silver Stream derivative liability as at December 31, 2024 was US$23,917,000 ($34,414,000).

During the year ended December 31, 2025, the Company recognized a liability of $5 million related to an obligation to the royalty holders of the Duquesne NSR. This amount reflects management's current estimate of the consideration that may be required to settle or repurchase the royalty interest, based on ongoing discussions with the royalty holders.

      12. SHARE CAPITAL (continued)
   3. Warrants

During the year ended December 31, 2025, the Company issued 53,808,807 (December 31, 2024 - nil) common shares pursuant to the exercise of warrants for an aggregate proceeds of $10,906,000 (2024 - $nil).

The movements in warrants during the years ended December 31, 2025 and 2024 are summarized as follows:

The following table summarizes information about warrants outstanding as at December 31, 2025:

The Company has adopted a stock option plan that allows for the granting of stock options to Directors, Officers, employees and certain consultants of the Company for up to 10% of the Company's issued and outstanding common shares. Stock options granted under the plan may be subject to vesting provisions as determined by the Board of Directors.

During the year ended December 31, 2025, the Company issued 8,012,500 (December 31, 2024 - nil) common shares pursuant to the exercise of stock options, for net proceeds of $1,157,000 (2024 - $nil).

In connection with the exercises, the Company transferred $583,000 (2024 - $nil) from share-based payment reserve to share capital.

The movements in stock options during the years ended December 31, 2025 and 2024 are summarized as follows:

The following table summarizes information about the stock options outstanding as at December 31, 2025:

During the year ended December 31, 2025, there were 19,800,000 (December 31, 2024 - 26,907,500) stock options granted with an aggregate fair value at the date of grant of $1,462,000 (December 31, 2024 - $1,521,000). As at December 31, 2025, 10,000,000 (December 31, 2024 - 13,247,500) stock options remain unvested with an aggregate grant date fair value of $360,000 (December 31, 2024 - $752,000).

Certain stock options granted were directly attributable to exploration and evaluation expenditures on mineral properties and were therefore capitalized to mineral properties.

In addition, certain stock options were subject to vesting provisions. These two factors result in differences between the aggregate fair value of stock options granted and total share-based payments expensed during the periods.

For the year ended December 31, 2025, share-based payments expense is comprised of stock options for $1,214,000, restricted share units ("RSUs") for $773,000, deferred share units ("DSUs") for $49,000, and performance share units ("PSUs") for $519,000, net with PSU assessment of $180,000, which are classified within the financial statements as follows:

The grant date fair value of the stock options granted in the period has been estimated using the Black-Scholes option pricing model with the following weighted average assumptions:

(1)The computation of expected volatility was based on the Company's historical price volatility, over a period which approximates the expected life of the option.

(2)The computation of the forfeiture rate was based on management's estimate of expected forfeitures over the vesting period, using historical forfeiture experience and expected employee turnover.

1. Restricted Share Units

   During the year ended December 31, 2025, the Company granted 7,756,956 (December 31, 2024 - 8,422,115) RSUs under its share-based compensation plan to the Company's executive officers and management as part of the Company's long-term incentive plan ("LTIP"). Unless otherwise stated, the awards typically have a graded vesting schedule over a three-year period and will be settled in equity upon vesting.

   During the year ended December 31, 2025, the Company issued 3,511,533 (December 31, 2024 - 1,094,168) common shares pursuant to the exercise of RSUs for an aggregate settlement value of $433,000 (2024 - $274,000).

   12. SHARE CAPITAL (continued)

   The associated compensation cost, which is based on the underlying share price on the date of grant, is recorded as share-based payments expense against share-based payment reserve.

   The following table summarizes the changes in RSU's for the years ended December 31, 2025 and 2024:

   	Number		Weighted average fair value
   Balance as at December 31, 2023	3,613,715	$	0.200

2. Deferred Share Units

   During the year ended December 31, 2025, the Company granted 400,000 (December 31, 2024 - 400,000) DSUs under its share-based compensation plan to a director as part of the Company's LTIP. DSUs have a graded vesting schedule over an 18-month period and will be settled in equity upon vesting.

   The associated compensation cost, which is based on the underlying share price on the date of grant, is recorded as share-based payments expense against share-based payment reserve.

   	Number		Weighted average fair value
   Balance as at December 31, 2023	1,109,000	$	0.250
   DSUs granted	400,000		0.106

3. Performance Share Units

During year ended December 31, 2025, the Company granted 3,600,000 (December 31, 2024 - 5,650,000) PSUs under the Plan to certain executives as part of the Company's LTIP. The amount of shares ultimately to be issued will vary from a factor of 0 to 2 based on the number of PSUs granted, depending on the Company's share performance as compared to the share performance of a selected group of peer companies.

The estimated value of the PSUs is determined at the grant date using a Monte Carlo simulation model. The model is based on several assumptions, including the grant date share price of the Company's common shares, share price volatility of the Company's stock, the volatility of the selected group of peer companies, the correlation of returns between the peer group and the Company, the risk-free interest rate over the term of the awards, the expected term to vesting, and the dividend yield. These assumptions are used in estimating the grant date fair value of the PSUs, which are subject to market-based performance conditions.

1. SHARE CAPITAL (continued)

   During the year ended December 31, 2025, the Company issued 758,000 (December 31, 2024 - Nil) common shares pursuant to the settlement of PSUs for an aggregate value of $180,000 (December 31, 2024 - $Nil).

   The following table summarizes the changes in PSUs for the years ended December 31, 2025 and 2024:

Fair values have been determined for measurement and/or disclosure requirements based on the methods below.

The Company characterizes fair value measurements using a hierarchy that prioritizes inputs depending on the degree to which they are observable. The three levels of the fair value hierarchy are as follows:

1. FAIR VALUE (continued)

   • Level 1 fair value measurements are quoted prices (unadjusted) in active markets for identical assets or liabilities;

   • Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

   • Level 3 fair value measurements are those derived from valuation techniques that include significant inputs for the asset or liability that are not based on observable market data (unobservable inputs).

     The carrying values of cash and cash equivalents, prepaid expenses and other receivables, and accounts payable, accrued and other liabilities approximated their fair values because of the short-term nature of these financial instruments. These financial instruments are financial assets and liabilities at amortized cost.

     The carrying value of marketable securities was based on the quoted market prices of the shares as at December 31, 2025 and was therefore considered to be Level 1.

     As at December 31, 2025, the Company's option liability relating to PC Gold Inc. is classified as a financial liability at FVTPL. The fair value of the option liability was estimated using a fair value less costs of disposal benchmark implied by the February 2026 BellaVista transaction (Note 20). The measurement is classified as Level 3 in the fair value hierarchy as it incorporates significant unobservable inputs, including assumptions related to probability-weighted performance rights and other contingent terms.

     The Silver Stream was determined to be a derivative liability, which is classified as a financial liability at FVTPL. The carrying value of the derivative liability was not based on observable market data and involved complex valuation methods and was therefore considered to be Level 3. Changes in key valuation assumptions, including commodity prices and discount rates, could result in significant fluctuations in the fair value of the liability. The loss on the Silver Stream derivative was due to 143% increase in volatility in the underlying precious metal, a 130% increase in the forward curve of the silver price, and a130% increase in the silver spot price as at December 31, 2025, compared to December 31, 2024.

     The following table presents the Company's fair value hierarchy for financial assets and liabilities that are measured at fair value:

2. FINANCIAL AND CAPITAL RISK MANAGEMENT

The Company thoroughly examines the various financial instruments and risks to which it is exposed and assesses the impact and likelihood of those risks. These risks include market risk (including equity price risk, foreign currency risk, interest rate risk and commodity price risk), credit risk, liquidity risk, and capital risk. Where material, these risks are reviewed and monitored by the Board of Directors.

The Board of Directors has overall responsibility for the determination of the Company's risk management objectives and policies. The overall objective of the Board is to set policies that seek to reduce risk as far as possible without unduly affecting the Company's competitiveness and flexibility.

1. Market Risk

   Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate due to changes in market prices. Market risk includes equity price risk, foreign currency risk, interest rate risk and commodity price risk.

   Equity Price Risk

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

   If the fair value of our investments in equity instruments designated as FVTOCI had been 10% higher or lower as at December 31, 2025, other comprehensive income (loss) for the year ended December 31, 2025 would have decreased or increased, respectively, by approximately $201,000 (2024 - $239,000), as a result of changes in the fair value of equity investments.

   Foreign Currency Risk

   The Company is exposed to financial risk related to fluctuation of foreign exchange rates. The sensitivity of the Company's net loss due to changes in the exchange rate between the US dollar against the Canadian dollar is included in the table below in Canadian dollar equivalents. As at December 31, 2025, the Company held USD denominated cash and cash equivalents of $10,201,000 (December 31, 2024 - $2,728,000). The Company has not hedged its exposure to currency fluctuations.

   Years ended December 31,

   	2025	2024
   Cash, cash equivalents	$ 10,201	$ 2,728
   Net exposure	$ 10,201	$ 2,728
   Effect of +/- 10% change in currency	$ 1,020	$ 273
   Interest Rate Risk

   Interest rate risk is the risk that future cash flows will fluctuate as a result of changes in market interest rates. The Company does not have any borrowings that are subject to fluctuations in market interest rate. Interest rate risk is limited to potential decreases on the interest rate offered on cash and cash equivalents held with chartered Canadian financial institutions. The Company manages its interest rate risk by seeking to optimize the interest income earned on excess funds while maintaining the necessary liquidity to conduct its day-to-day operations. The Company considers this risk to be immaterial.

   19. FINANCIAL AND CAPITAL RISK MANAGEMENT (continued)

   Commodity price risk

   The Company is subject to commodity price risk from fluctuations in the market prices for silver. Commodity price risks are affected by many factors that are outside the Company's control including global or regional consumption patterns, the supply of and demand for metals, speculative activities, the availability and costs of metal substitutes, inflation, and political and economic conditions. The financial instrument impacted by commodity prices is the Silver Stream derivative liability. The Company's net loss would have increased or decreased by approximately $10.4 million if the commodity price had been 10% higher or lower as at December 31, 2025.

2. Credit Risk

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

3. Liquidity Risk

   Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company's policy is to try to ensure that it will have sufficient cash to allow it to meet its liabilities when they become due. The Company manages its liquidity risk by preparing annual estimates of exploration and administrative expenditures and monitoring actual expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.

   The Company's operations to date have been financed by the issuance of common shares, sale of investments, assets, and royalties and the exercise of stock options. The Company expects to fund continuing and future operations through a combination of additional financing, the realization of value from its investments and other assets, and prudent management of expenditures.

   The following table summarizes the maturities of the Company's financial liabilities as at December 31, 2025 based on the undiscounted contractual cash flows. The Company's Silver Stream derivative liability is also a financial liability; however, as settlement is not expected within the next five years, it has not been included in the table below.

   	Carrying Amount	Contractual Cash Flows	Less than 1 year	1 - 3 years	4 - 5 years
   Accounts payable
   and accrued liabilities $ 13,802		$ 13,802	$ 13,802	$ - $ -
   Accounts payable and accrued liabilities AHFS 373		373	373	- -
   Other liabilities 200		200	200	-
   Lease liability	175	195	92	103	-
   Total	$ 14,550	$ 14,570	$ 14,467	$ 103	$ -

   As at December 31, 2025, the Company held cash and cash equivalents of $43,346,000 (December 31, 2024 -

   $11,351,000).

   1. FINANCIAL AND CAPITAL RISK MANAGEMENT (continued)
4. Capital Risk Management

The Company's objectives when managing capital are to safeguard the Company's ability to continue as a going concern in order to pursue the exploration and retention of its mineral properties. In the management of capital, the Company includes the components of shareholders' equity. The Company prepares annual estimates of exploration and administrative expenditures and monitors actual expenditures compared to the estimates to ensure that there is sufficient capital on hand to meet ongoing obligations.
