Notes to Condensed Interim Consolidated Financial Statements

For the three months ended March 31, 2025 and 2024

(Unaudited – Tabular amounts presented in thousands of US dollars, except share and per share amounts)

1. NATURE OF OPERATIONS

Fortuna Mining Corp. (the "Company"), is a publicly traded company incorporated and domiciled in British Columbia, Canada.

The Company is engaged in precious and base metal mining and related activities in Argentina, Burkina Faso, Côte d'Ivoire, Mexico, Peru and Senegal. The Company operates the open pit Lindero gold mine ("Lindero") in northern Argentina, the open pit Séguéla gold mine ("Séguéla") in southwestern Côte d'Ivoire, the underground Caylloma silver, lead, and zinc mine ("Caylloma") in southern Peru, and the underground and open pit Yaramoko gold mine ("Yaramoko") in southwestern Burkina Faso, and is developing the Diamba Sud gold project in Senegal. Subsequent to March 31, 2025, the Company entered into a definitive share purchase agreement to sell its 100% interest in Roxgold SANU S.A., which owns and operates the Yaramoko mine. The sale is expected to be completed in the second quarter of 2025 (see Note 28). Additionally, on April 11, 2025, the Company completed the sale of its 100% interest in Compania Minera Cuzcatlan S.A. de C.V. ("Cuzcatlan"), which owns the San Jose mine (see Note 28).

The Company's common shares are listed on the New York Stock Exchange (the "NYSE") under the trading symbol FSM and on the Toronto Stock Exchange (the "TSX") under the trading symbol FVI.

In January 2025, the Company relocated its head office to Suite 820, 1111 Melville Street, Vancouver, British Columbia V6E 3V6, Canada. As at March 31, 2025, the Company's registered office was located at Suite 3500, 1133 Melville Street, Vancouver, British Columbia V6E 4E5, Canada.

2. BASIS OF PRESENTATION

Statement of Compliance

These unaudited condensed interim consolidated financial statements ("interim financial statements") have been prepared by management of the Company in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") applicable to the preparation of interim financial statements, including IAS 34 Interim Financial Reporting. They do not include all the information required for full annual financial statements. These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2024, which include information necessary for understanding the Company's business and financial presentation.

Other than as described below, the same accounting policies and methods of computation are followed in these interim financial statements as compared with the most recent annual financial statements.

On May 7, 2025, the Company's Board of Directors approved these interim financial statements for issuance.

Basis of Measurement

These financial statements have been prepared on a going concern basis under the historical cost basis, except for those assets and liabilities that are measured at fair value (Note 24) at the end of each reporting period.

Adoption of new accounting standards

The Company adopted various amendments to IFRS, which were effective for accounting periods beginning on or after January 1, 2025. These include amendments to IAS 21, Lack of Exchangeability. The impacts of adoption were not material to the Company's interim financial statements.

(Unaudited – Tabular amounts presented in thousands of US dollars, except share and per share amounts)

3. USE OF ESTIMATES, ASSUMPTIONS, AND JUDGEMENTS

The preparation of these interim financial statements requires management to make estimates and judgements that affect the reported amounts of assets and liabilities at the period end date and reported amounts of expenses during the reporting period. Such judgements and estimates are, by their nature, uncertain. Actual outcomes could differ from these estimates.

The impact of such judgements and estimates are pervasive throughout the interim financial statements, and may require accounting adjustments based on future occurrences. These judgements and estimates are continuously evaluated and are based on management's experience and knowledge of the relevant facts and circumstances. Revisions to accounting estimates are recognized in the period in which the estimate is revised and are accounted for prospectively.

In preparing these interim financial statements for the three months ended March 31, 2025, the Company applied the critical estimates, assumptions and judgements as disclosed in Note 4 of its audited consolidated financial statements for the year ended December 31, 2024.

4. TRADE AND OTHER RECEIVABLES

March 31, 2025 $ December 31, 2024 $
Trade receivables from doré and concentrate sales 18,430 26,702
Advances and other receivables 4,836 4,332
Value added tax receivables 72,637 68,950
Trade and other receivables 95,903 99,984

The Company's trade receivables from concentrate and doré sales are expected to be collected in accordance with the terms of the existing concentrate and doré sales contracts with its customers. No amounts were past due as at March 31, 2025.

As at March 31, 2025, current Value Added Tax ("VAT") receivables include $18.6 million (December 31, 2024 - $20.4 million) for Argentina, $nil (December 31, 2024 - $4.3 million) for Mexico, $31.0 million (December 31, 2024 - $22.2 million) for Côte d'Ivoire, and $21.0 million (December 31, 2024 - $20.6 million) for Burkina Faso. An additional $31.6 million (December 31, 2024 - $28.4 million) of VAT receivables are classified as non-current (refer to Note 8).

VAT receivables from the fiscal authorities in Burkina Faso are not in dispute and are deemed to be fully recoverable. The most recent refund was received in August 2024. The Company is following the relevant process in Burkina Faso to recoup the VAT receivables and continues to engage with authorities to accelerate the repayment of the outstanding balance.

The Company has an investment strategy, which includes utilizing certain foreign exchange measures implemented by the Argentine Government, to address its local currency requirements in Argentina. As a result of this strategy, during the three months ended March 31, 2025, the Company recorded investment gains of $1.3 million (March 31, 2024 - $2.6 million) from trades in Argentine peso denominated cross-border securities.

(1) In July 2021, the Company completed the acquisition of Roxgold Inc. including its Boussoura exploration property in Burkina Faso. However, in December 2024, the Company confirmed that substantive expenditure on further exploration and evaluation of mineral resources at the Boussoura site is neither budgeted nor planned. As such, no future value is expected from the Boussoura property. Therefore, the carrying amount of the exploration and evaluation asset exceeded its recoverable amount and the Company recorded a write-off of the exploration property of $14.5 million. The Company reversed its deferred tax liability of $1.6 million related to exploration and evaluation assets subsequently to recording a write-off.

(2) In December 2024, the Company concluded a comprehensive review of its capitalized exploration costs associated with mineral properties. This review involved an analysis of drilling meters, exploration costs incurred to date, and an assessment of the likelihood of each prospect becoming part of the Company's mineral reserves. As a result of this review, certain prospects previously classified as depletable at the Séguéla mine were reclassified as non-depletable mineral properties, resulting in a net transfer of $13.7 million from depletable to non-depletable mineral properties. This reclassification reflects the updated assessment of the long-term economic viability and recoverability of mineral resources associated with these prospects and represents a true-up between depletable and non-depletable categories.

22. ASSETS HELD FOR SALE AND DISCONTINUED OPERATION

(a) Accounting Policy – Assets Held for Sale and Discontinued Operation

The Company classifies non-current assets and disposal groups as held for sale when their carrying amounts are expected to be recovered principally through a sale transaction rather than through continuing use. Assets or disposal groups classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell. Costs to sell are the incremental costs directly attributable to the disposal, excluding finance costs and income tax expense.

Classification as held for sale is appropriate only when the sale is highly probable, the asset or disposal group is available for immediate sale in its present condition, and management is committed to a plan to sell. The sale must be expected to complete within one year from the date of classification, and it must be unlikely that significant changes to or withdrawal of the plan will occur. Property, plant and equipment and intangible assets are not depreciated or amortized once classified as held for sale. Related assets and liabilities are presented separately as current items in the statement of financial position.

A discontinued operation is a component of the Company that has been disposed of or is classified as held for sale and represents a separate major line of business or geographical area of operations. The results of discontinued operations are excluded from continuing operations and are presented as a single amount, net of tax, in the statement of profit or loss.

(b) Accounting Disclosure

On March 31, 2025, the Company was committed to a plan to sell its interest in Cuzcatlan, which owns and operates the San Jose Mine in Oaxaca, Mexico. As a result, the assets and liabilities of Cuzcatlan have been classified as held for sale, and its operating results have been presented as a discontinued operation in the condensed interim consolidated financial statements for the three months ended March 31, 2025.

The Company recognized a single amount of post-tax profit or loss from the discontinued operation in the condensed interim consolidated statement of income. Comparative information for the three months ended March 31, 2024, has been restated to reflect the results of the San Jose Mine as a discontinued operation, separately from continuing operations.

27. CONTINGENCIES AND CAPITAL COMMITMENTS

(a) Caylloma Letter of Guarantee

The Caylloma mine closure plan, as amended, that was in effect in September 2024, includes total undiscounted closure costs of $18.2 million, which consisted of progressive closure activities of $2.4 million, final closure activities of $13.5 million, and post closure activities of $2.3 million pursuant to the terms of the Mine Closing Law of Peru.

Under the terms of the current Mine Closing Law, the Company is required to provide the Peruvian Government with a guarantee in respect of the Caylloma mine closure plan as it relates to final closure activities and post-closure activities and related taxes. As at March 31, 2025, the Company provided a bank letter guarantee of $15.2 million to the Peruvian Government in respect of such closure costs and taxes.

(b) Other Commitments

Argentina

As at March 31, 2025, the Company had capital commitments of $5.7 million, for civil work, equipment purchases and other services at the Lindero mine, which are expected to be expended within one year.

Côte d'Ivoire

The Company entered into an agreement with a service provider at the Séguéla mine wherein if the Company terminates the agreement prior to the end of its term, in November 2026, the Company would be required to make an early termination payment, which is reduced monthly over 48 months. If the Company had terminated the agreement on March 31, 2025, and elected not to purchase the service provider’s equipment, it would have been subject to an early termination payment of $15.3 million. If the Company elected to purchase the service provider’s equipment, the early termination amount would be adjusted to exclude equipment depreciation and demobilization of equipment, and only include portion of the monthly management fee and demobilization of personnel.

Additional early termination payments may apply under certain other service agreements, amounting to an approximate cumulative fee of $4.5 million as at March 31, 2025.

(c) Tax Contingencies

The Company is, from time to time, involved in various tax assessments arising in the ordinary course of business. The Company cannot reasonably predict the likelihood or outcome of these actions. The Company has recognized tax provisions with respect to current assessments received from the tax authorities in the various jurisdictions in which the Company operates, and from any uncertain tax positions identified. For those amounts recognized related to current tax assessments received, the provision is based on management’s best estimate of the outcome of those assessments, based on the validity of the issues in the assessment, management’s support for their position, and the expectation with respect to any negotiations to settle the assessment. Management re-evaluates the

outstanding tax assessments regularly to update their estimates related to the outcome for those assessments taking into account the criteria above.

Pillar Two Global Minimum Tax

On June 30, 2024, the Global Minimum Tax Act ("GMTA") received royal assent, introducing the Pillar Two global minimum tax regime in Canada. The GMTA is based on the OECD's Pillar Two Global Anti-Base Erosion (GloBE) model rules and applies to fiscal years beginning after December 31, 2023. The legislation includes the income inclusion rule and a qualified domestic minimum top-up tax, and contains a placeholder for the undertaxed profits rule, which is proposed to be effective for fiscal years beginning after December 31, 2024.

The Pillar Two regime applies to multinational enterprise groups with consolidated revenues of at least EUR 750 million in at least two of the four fiscal years immediately preceding a given fiscal year. As the Company exceeded the threshold for a second time in 2024, Pillar Two legislation is applicable to the Company from January 1, 2025.

As at March 31, 2025, Pillar Two legislation has only been enacted in Canada among the jurisdictions in which the Company operates. The Company is in the process of assessing the potential impact of Pillar Two legislation, including the application of the transitional safe harbour rules. No Pillar Two top-up taxes have been recognized in the interim financial statements for the three months ended March 31, 2025.

(d) Other Contingencies

The Company is subject to various investigations and other claims; and legal, labour, and tax proceedings covering matters that arise in the ordinary course of business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be resolved unfavourably for the Company. Certain conditions may exist as of the date these financial statements are issued that may result in a loss to the Company. None of these matters is expected to have a material effect on the results of operations or financial conditions of the Company.

  1. SUBSEQUENT EVENTS

Subsequent events not otherwise mentioned are as follows:

(a) Sale of the San Jose Mine

On April 11, 2025, the Company completed the sale of its 100% interest in Cuzcatlan, which owns the San Jose mine in Oaxaca, Mexico, to JRC, a private Peruvian company. Under the terms of the definitive share purchase agreement, JRC acquired all of the issued and outstanding shares of Cuzcatlan in consideration for $6.5 million, which was received on closing. Post closing JRC has paid $1.2 million for prepaid working capital items and tax receivables. The Company also has the right to receive contingent consideration of up to approximately $8.3 million, subject to the completion of certain conditions, of which $4.7 million has been received to date. Furthermore, the Company retains a 1.0% net smelter royalty on production from the San Jose Mine concessions payable after the first 6.1 million ounces of silver and the first 44,000 ounces of gold (or 119,000 gold equivalent ounces) have been mined or extracted from the property.

This transaction supersedes the previously disclosed binding letter agreement for the sale of Cuzcatlan to Minas del Balsas S.A. de C.V., which did not proceed.

(Unaudited – Tabular amounts presented in thousands of US dollars, except share and per share amounts)

(b) Sale of the Yaramoko Mine

On April 11, 2025, the Company entered into a definitive share purchase agreement to sell all of its interest in Roxgold Sanu, which owns and operates the Yaramoko mine, together with the Company's three other wholly-owned Burkina Faso subsidiaries that hold exploration permits in the country, to Soleil Resources International Limited, a private Mauritius company, for consideration of $70M in cash upon closing and the right to receive up to $53.0 million in VAT receivables payable upon the completion of certain conditions. The completion of the Burkina Faso Transaction is subject to the payment of a cash dividend by Roxgold Sanu to Fortuna in the amount of $53.8 million plus $3.7 million in withholding tax. The sale is subject to customary closing conditions, including the approval of the Burkina Faso Minister of Mines, and is expected to close in the second quarter of 2025. Upon completion, the Company will cease all operations in Burkina Faso.

As of May 07, 2025, Roxgold Sanu has paid the $53.8 million dividend and the necessary withholding taxes.

This transaction represents a non-adjusting subsequent event as defined by IAS 10, Events After the Reporting Period. The criteria for classification as held for sale in accordance with IFRS 5, Non-current Assets Held for Sale and Discontinued Operations, were not met as of March 31, 2025. Accordingly, the carrying amounts of the four entities have not been reclassified as held for sale, and no adjustments have been made to the amounts recognized in these financial statements for the three months ended March 31, 2025.

(c) Ad Valorem Tax Rates Increase for Burkina Faso Operations

On April 7, 2025, the Burkina Faso government announced an increase in ad valorem tax on gold sales, effective immediately. The new tax regime introduces a change to the gold royalties for gold sold above $3,000 per ounce. An additional 1% royalty is payable for each $500 increment in the gold price above $3,000 per ounce. The previous cap was 7% of gold sales over $2,000 per ounce. These changes are not expected to materially impact the Company's financial position and results of operations.
