FIRST MINING GOLD CORP.

NOTES TO THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(Presented in Canadian dollars unless otherwise noted, tabular amounts are presented in thousands of Canadian dollars except for number of shares and per share amount)

1. NATURE OF OPERATIONS AND GOING CONCERN

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. First Mining's portfolio of gold projects in eastern Canada also includes the Cameron project. 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"), and a 20% direct project interest in the Hope Brook Project.

Going Concern

The Company's unaudited condensed interim 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 March 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 will require additional financing or outside participation to undertake further advanced exploration of its mineral properties. Future operations of the Company are dependent upon its ability to raise additional equity financing and maintain sufficient working capital and upon future production or proceeds from the dispositions of its mineral property interests.

As at March 31, 2025, the Company had cash and cash equivalents of $10,102,000 (December 31, 2024 - $11,351,000), working capital of $3,499,000 (December 31, 2024 - $744,000) which is calculated as current assets less current liabilities, and accumulated a deficit of $199,982,000 (December 31, 2024 - $180,895,000). The Company had a working capital balance of $7,473,000 (December 31, 2024 - $4,718,000), excluding the 10% Option on PC Gold with Firefly from current liabilities, as it does not require a cash outlay. An unspent flow-through expenditure of $3,338,000 (December 31, 2024 - $4,197,000) is required to be spent by December 31, 2025. During the three months ended March 31, 2025, the Company incurred a net loss of $19,087,000 (2024 - $18,300,000) and used cash in operating activities of $1,817,000 (2024 - $2,036,000). 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 continuing operations of the Company are dependent upon its ability to continue to raise adequate financing and liquidate its investments as necessary. There can be no assurance that the Company will be able to continue to secure additional financings in the future, and if they are secured, that they would be on terms that are favourable. This gives rise to a material uncertainty that may raise substantial doubt about the Company's ability to continue as a going concern.

These financial statements do not give effect to any adjustments to the carrying values of the assets and liabilities, the reported expenses, and the statements of financial position classifications used that would be necessary should the Company be unable to continue as going concern. Such adjustments could be material.

2. BASIS OF PRESENTATION

These financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards") applicable to the preparation of interim financial statements under International Accounting Standard 34 Interim Financial Reporting. These financial statements do not include all disclosures required for annual financial statements. Accordingly, they should be read in conjunction with the Company's audited financial statements for the years ended December 31, 2024 and 2023.

The financial statements are presented in thousands of Canadian dollars, unless otherwise noted, and tabular amounts are presented in thousands of Canadian dollars. These consolidated financial statements include the accounts of the Company and its subsidiaries. The functional currency of the Company and its subsidiaries is the Canadian dollar.

In preparing the Company's financial statements for the three months ended March 31, 2025, the Company used the consistent accounting policies, methods of computation and accounting policy judgments and estimates as in the annual consolidated financial statements for the year ended December 31, 2024. Additionally, the areas of estimation uncertainty remain unchanged from those disclosed in the annual consolidated financial statements.

Certain new accounting standards and interpretations have been published that are either applicable in the current year or not mandatory for the current period. We have 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 in the current reporting period. In addition, the following standards have been issued by the International Accounting Standards Board ("IASB") and we are currently assessing the impact on our consolidated financial statements.

  • Amendments to the Classification and Measurement of Financial Instruments (IFRS 9 and IFRS 7) with mandatory application of the standard in annual reporting periods beginning on or after January 1, 2026.
  • IFRS 18 Presentation and Disclosure in Financial Statements with mandatory application of the standard in annual reporting periods beginning on or after January 1, 2027.

No standards have been early adopted in the current period. The Company is still assessing whether any of the new standards are expected to have a material impact on its consolidated financial statements.

The accounts of material subsidiaries are prepared for the same reporting period as the parent company. All subsidiaries apply consistent accounting policies. Inter-company transactions, balances and unrealized gains or losses on transactions are eliminated. The following table highlights the Company's material subsidiaries with their projects:

Name of the subsidiary Ownership Percentage Project Location
Gold Canyon Resources Inc. 100% Springpole Gold Project ("Springpole")

5. 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.

a) Birch-Uchi Properties

(i) Swain Lake property option

On April 28, 2021, the Company entered into an earn-in agreement with Whitefish Exploration Inc. ("Whitefish"), which gives First Mining the option to earn up to a 100% interest in Whitefish's Swain Lake project ("Swain Lake") in northwestern Ontario in two stages over a period of five years. First Mining may earn a 70% interest in Swain Lake by making cash payments totaling $200,000 and share payments totaling $425,000, and by incurring at least $500,000 worth of expenditures on the Swain Lake Property during the first three years of the earn-in term. Upon completing the first stage of the earn-in, First Mining will hold a 70% interest in the Swain Lake Property and will have an additional period of two years within which to acquire the remaining 30% interest in the Swain Lake Property by paying $1,000,000 in cash and issuing First Mining common shares with a fair value of $1,000,000 to Whitefish.

On April 5, 2024, the Company and Whitefish agreed to amend the earn-in agreement to amend the future cash and share payment requirements by issuing First Mining common shares with a fair value of $155,000 (based on market price at the time of issuance) to Whitefish on or before the third anniversary of the Closing Date of the original agreement. In Q2 2024, the Company issued 978,130 common shares valued at $155,000, under the terms of the amended earn-in agreement. As a result, the Company completed its 3-year option agreement with Whitefish Exploration Inc. on the Swain Lake property, and 70% ownership of the property, which comprises 82 mining claims over an area of 1,656 hectares, was transferred to First Mining.

(ii) Vixen properties acquisition

On September 15, 2021, the Company entered into a three-year option agreement with ALX Resources Corp. ("ALX") pursuant to which First Mining may earn up to a 100% interest in ALX's Vixen North, Vixen South and Vixen West properties (the "Vixen Properties") in northwestern Ontario in two stages over a period of five years. First Mining may earn a 70% interest in the Vixen Properties by making cash payments totalling $550,000 and share payments totalling $400,000 to ALX during the initial three-year option term, and by incurring at least $500,000 worth of expenditures on the property during the initial three-year option term.

On September 15, 2023, the Company and ALX agreed to amend the option agreement for the first stage of the earn-in to issue common shares instead of cash payment for future anniversary payments as follows:

  • On or before the second anniversary of the Closing Date, the Company is to issue to ALX common shares of the Company's shares with a fair value of $175,000 (issued);
  • On or before the third anniversary of the Closing Date, the Company is to issue to ALX common shares of the Company's shares with a fair value of $175,000 (issued);
  • On or before the fourth anniversary of the Closing Date, the Company is to issue to ALX common shares of the Company's shares with a fair value of $100,000;
  • On or before the fifth anniversary of the Closing Date, the Company to incur and fund expenditures on the property of not less than $500,000.

Pursuant to the amended agreement, on September 12, 2024 the Company issued 1,290,045 common shares with a fair value of $175,000. As at March 31, 2025, the Company has made payments of $350,000 in cash and issued common shares with a fair value of $550,000.

5. MINERAL PROPERTIES (continued)

(iii) Birch Lake properties acquisition

On October 11, 2021, the Company entered into an earn-in agreement with Pelangio Exploration Inc. ("Pelangio") pursuant to which First Mining may earn up to an 80% interest in Pelangio's Birch Lake properties (the "Birch Lake Properties") in two stages over a period of six years. First Mining may earn a 51% interest in the Birch Lake Properties by making cash payments totaling $350,000 and issuing in aggregate 1,300,000 First Mining common shares and by incurring at least $1,750,000 worth of expenditures on the Birch Lake Properties during the first four years of the earn-in term. Upon completing the first stage of the earn-in, First Mining will hold a 51% interest in the Birch Lake Properties and will have an additional period of two years to acquire a further 29% interest in the Birch Lake Properties by paying $400,000 to Pelangio in cash or issuing First Mining common shares, at First Mining's sole discretion, and by incurring an additional $1,750,000 worth of expenditures on the Birch Lake Properties.

On October 12, 2023, the Company and Pelangio agreed to amend the earn-in agreement to amend the future cash and share payment requirements to have an additional period of 3 years to complete the first stage of the earn-in. Pursuant to the amended agreement, the Company paid $10,000 in cash and issued 250,000 common shares during the three months ended December 31, 2023. On October 11, 2024, the Company made a cash payment of $10,000 and issued 250,000 common shares to Pelangio on the first anniversary of the Closing Date of the amended earn-in agreement for Birch Lake properties. The agreement gives the Company the right to earn, through Gold Canyon, up to an 80% interest in Pelangio's Birch Lake and Birch Lake West properties. As at March 31, 2025, the Company has made payments of $120,000 in cash and issued common shares with a fair value of $187,500 (December 31, 2024 - $187,500).

On January 13, 2023, a subsidiary of the Company acquired the net assets of a private company associated with Birch Lake and Casummit Lake properties for a total consideration of $600,000 cash and 3,500,000 of First Mining common shares. $100,000 was paid prior to December 31, 2022, $100,000 cash was paid on closing, with the remaining cash to be paid as follows:

  • 500,000 issued in January 2024, the first anniversary of the Closing Date.
  • 1,000,000 common shares will be issued on the earlier of the third anniversary of closing and the date of a positive decision regarding the environmental assessment of the Springpole properties.

(iv) Stargazer properties acquisition

On October 29, 2021, the Company entered into a three year earn-in agreement with a private individual pursuant to which First Mining may earn a 100% interest in the Stargazer concession and other properties ("Stargazer Properties") in northwestern Ontario by making cash and share payments of $250,000 to the private individual during the term of the option, and by incurring at least $350,000 worth of expenditures on the Stargazer Properties during the three-year option term.

On November 5, 2023, the Company entered into an amended agreement to amend the original terms of cash and share payments of $250,000 to $236,000 and the Company is to incur $300,000 worth of expenditures instead of $350,000. The remaining share payments will be issued as follows:

As at March 31, 2025, the Company has made payments of $24,000 in cash and issued common shares with a fair value of $12,000.

b) Duparquet Project

As at March 31, 2025, the Company's provision for environmental remediation activities is $3,000,000 (December 31, 2024 - $3,000,000). 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 with the Ministry of Environment, the Fight Against Climate Change, Wildlife and Parks ("MELCCFP") and submitted a permit to begin start work in 2025. The environmental remediation estimate is based on the current work plan. The final environmental remediation cost may vary depending on feedback received from MELCCFP and the execution of the work.

c) Hope Brook Project

On June 8, 2021, the Company announced it had closed a definitive earn-in agreement with Big Ridge Gold Corp. whereby Big Ridge could earn up to an 80% interest in First Mining's Hope Brook Gold Project located in Newfoundland, Canada. In accordance with the agreement, upon closing First Mining nominated one member to the Board of Directors of Big Ridge and received $500,000 and 11,500,000 shares of Big Ridge which were credited against the Hope Brook project mineral property balance. On September 13, 2022, Big Ridge completed Stage 1 of the earn-in requirements. On March 21, 2024, the Company and Big Ridge amended the earn-in agreement by removing the requirement for Big Ridge to incur an additional $10,000,000 in expenditures on the Hope Brook Gold Project in order to facilitate the Company's liquidation of its investment position in Big Ridge and generate additional capital. On March 28, 2024, Big Ridge exercised Stage 2 of the amended earn-in requirement by issuing the Company 10,000,000 Big Ridge common shares (initial recognition - $800,000), decreasing the Company's ownership percentage in the Hope Brook Project from 49% to 20% and reducing the pre-impairment carrying value by $800,000. The Company tested the recoverable amount of the retained project interest; using a market approach to determine the estimated fair value, an impairment loss of $11,955,000 was recognized during the period ended March 31, 2024.

6. INVESTMENT IN PC GOLD INC.

Pursuant to a definitive Earn-in agreement ("Earn-in") the Company and FireFly Metals executed on March 12, 2020, comprised of two stages, on June 9, 2021, the Company announced completion of the Stage 1 earn-in and accordingly FireFly Metals obtained a 51% ownership of the PC Gold legal entity. First Mining received the scheduled 100,000,000 FireFly Metals shares and executed the joint venture shareholders agreement. Following the completion of the Stage 1 earn-in by FireFly Metals, the Company's percentage ownership of its former subsidiary, PC Gold, was reduced from 100% to 49%, which led to a loss of control and the resulting deconsolidation of PC Gold Inc. from First Mining's financial statements.

6. INVESTMENT IN PC GOLD INC. (continued)

First Mining determined that its then 49% investment in the common shares of PC Gold gave it significant influence over PC Gold, requiring PC Gold to be recorded in First Mining's financial statements using the equity method of accounting as an investment in associate. Upon the completion of the Stage 2 earn-in by FireFly Metals in August 2021, the Company's percentage ownership reduced from 49% to 30%.

The initial recognition of the investment in an associate was accounted for based on an estimated fair value using a market approach to value Pickle Crow's inferred resources on a per unit of metal basis derived from comparable gold project transactions. As at March 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 March 31, 2025, the carrying value of the investment in PC Gold Inc. was $21,525,000 (December 31, 2024 - $21,527,000).

The subsequent equity accounting for PC Gold is based on audited results that is publicly available information for the year-ended June 30, 2024, and on the unaudited nine-month period ended March 31, 2025.

As at March 31, 2025, the Company has recorded an option liability of $3,974,000 (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 pro-rata share of environmental reclamation funding, which was 30% as at March 31, 2025.

As at March 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.

7. PROPERTY AND EQUIPMENT

On April 28, 2023, the Company acquired real and personal property for $800,000 in cash and 1,000,000 common shares of the Company from a private company and individual on the following payment terms:

  • $200,000 cash payable on the closing date and issue 1,000,000 shares (paid).
  • $300,000 cash payable on or before the first anniversary of the closing date (paid).
  • $300,000 cash payable on or before the second anniversary of the closing date.

8. SILVER STREAM DERIVATIVE LIABILITY

a) 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 also 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.

NOTES TO THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(Presented in Canadian dollars unless otherwise noted, tabular amounts are presented in thousands of Canadian dollars except for number of shares and per share amount)

8. SILVER STREAM DERIVATIVE LIABILITY (continued)

First Mining has the right to repurchase 50% of the Silver Stream for US$22.5 million (approximately C$32.3 million as at March 31, 2025) at any time prior to the commencement of production at Springpole (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 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) is payable by First Majestic upon First Mining receiving approval of a federal or provincial environmental assessment for the Springpole Gold Project, which is 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 shall be due and owing by the Company to First Majestic.

The silver delivered to First Majestic may be sourced from the Springpole Gold Project, or the Company may substitute any required refined silver with refined silver from a source other than the Springpole Gold Project, with the exception of silver purchased on a commodity exchange.

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.

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 has revised the exercise price of the Warrants to $0.20 and extended the expiry date of the Warrants to March 31, 2028. Pursuant to the terms of the amended Warrants, the Company can accelerate the expiry date of the Warrants if the closing price of the Company's common shares on the TSX equals or exceeds $0.30 for 45 consecutive trading days, to the date which is 30 days following the dissemination of a news release announcing the acceleration. 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 remain unchanged.

b) 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 Company's credit spread, historical volatility of the warrant and payable silver quantities. The fair value of the Silver Stream derivative liability is a Level 3 measurement.

8. SILVER STREAM DERIVATIVE LIABILITY (continued)

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 March 31, 2025, the fair value of the Silver Stream derivative liability is US$40,016,000 ($57,527,000). The fair value of the Silver Stream derivative liability as at December 31, 2024 was US$23,917,000 ($34,414,000), which is comprised of the Silver Stream obligation fair value of US$27,706,000 ($39,867,000) less the Advance Payment receivable fair value of US$3,789,000 ($5,453,000).

During the three months ended March 31, 2025, there were 17,800,000 (year ended December 31, 2024 - 26,607,500) stock options granted with an aggregate fair value at the date of grant of $1,111,862 (year ended December 31, 2024 - $1,500,715). As at March 31, 2025, 19,977,000 (year ended December 31, 2024 - 23,760,625) stock options remain unvested with an aggregate grant date fair value of $1,209,575 (December 31, 2024 - $1,503,560).

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 three months ended March 31, 2025, share-based payments expense is comprised of stock options for $504,767, restricted share units ("RSUs") for $176,187, deferred share units ("DSUs") for $21,237, and performance share units ("PSUs") for $125,290, which are classified within the financial statements as follows:

e) Restricted Share Units

During the three months ended March 31, 2025, the Company granted 7,756,956 (year ended 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 three months ended March 31, 2025, the Company issued 1,078,130 (2024 - 223,334) common shares pursuant to the exercise of RSUs for an aggregate settlement value of $114,686 (2024 - $73,090).

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.

g) Performance Share Units

During the three months ended March 31, 2025, the Company granted 3,600,000 (year ended 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 share price volatility of the Company's stock, as well as the volatility of the selected group of peer companies and the correlation of returns between the peer group and the Company.

The following table summarizes the changes in PSUs for the three months ended March 31, 2025 and year ended December 31, 2024:

Number Weighted average fair value
Balance as at December 31, 2023 6,813,000 $ 0.23
PSUs granted 5,650,000 0.09
PSU forfeited (1,997,000) 0.22
Balance as at December 31, 2024 10,466,000 $ 0.16
PSUs granted 3,600,000 0.13
Balance as at March 31, 2025 14,066,000 $ 0.15

Prior to vesting, the Company's PSUs are subject to a market-based performance condition, measured by the Company's relative total shareholder return performance against a defined peer group over a three-year period. Accordingly, the PSUs issued during the year ended December 31, 2022, which vested during the three months ended March 31, 2025, were evaluated against the performance condition. Following this evaluation, the number of PSUs that ultimately vested was lower than estimated at initial recognition, resulting in a reversal of $180,000 of previously recognized expense.

15. FAIR VALUE

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

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

  • Level 1 fair value measurements are quoted prices (unadjusted) in active markets for identical assets or liabilities;
  • Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
  • Level 3 fair value measurements are those derived from valuation techniques that include significant inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The carrying values of cash and cash equivalents, marketable securities, 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 is based on the quoted market prices of the shares as at March 31, 2025 and was therefore considered to be Level 1.

As the FireFly Metals Earn-In Agreement provides FireFly Metals the right to earn an interest in PC Gold Inc., rather than a direct interest in the Pickle Crow project, FireFly Metals' option to acquire PC Gold shares is a financial liability of First Mining. As a derivative, the Pickle Crow project option liability is classified as financial liability at FVTPL. The carrying value of the Option is not based on observable market data and therefore is considered to be Level 3.

The fair value of the Pickle Crow project option liability as at December 31, 2024, was determined by reference to the portion of the estimated fair value of PC Gold Inc. to be given up by the Company with the option for FireFly Metals to earn an additional 10%, net of $3,000,000 proceeds to be received on exercise.

15. FAIR VALUE (continued)

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 a $13\%$ increase in volatility, a $16\%$ increase in the forward curve, and a $15\%$ increase in the spot rate as at March 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:

March 31, 2025 December 31, 2024
Carrying value Fair value measurement Carrying value Fair value measurement
Level 1 Level 2 Level 3 Level 1 Level 2 Level 3
Financial assets:
Marketable Securities (Note 3) $ 1,630 $ 1,630 $ - $ - $ 2,388 $ 2,388 $ - $ -
Financial liabilities:
Silver Stream derivative liability (Note 8) $ 57,527 $ - $ - $ 57,527 $ 34,414 $ - $ - $ 34,414
Option – PC Gold (Note 6) $ 3,974 $ - $ - $ 3,974 $ 3,974 $ - $ - $ 3,974
