SUPPLEMENT DISCLOSURES WITH RESPECT TO CASH FLOWS (Note 14)

The accompanying notes are an integral part of these condensed interim consolidated financial statements.

Foremost Clean Energy Ltd. (“Foremost” or the "Company") which was incorporated under the laws of the Province of British Columbia, is a public company listed on the Canadian Securities Exchange (the “CSE”) and trades under the symbol FAT and on the NASDAQ Capital Market (“NASDAQ”) under the symbols FMST and FMSTW. The Company’s head office is located at 250 – 750 West Pender Street, Vancouver, BC, V6C 2T7.

Going concern of operations

These condensed interim consolidated financial statements have been prepared on a going concern basis which assumes that the Company will be able to realize its assets and discharge its liabilities in the normal course of business for the foreseeable future. As at June 30, 2025, the Company has had significant losses resulting in a deficit of $23,527,874 (March 31, 2025 - $24,455,404). In addition, the Company has not generated revenues from operations. The Company has financed its operations primarily through the issuance of common shares and short-term loans. The Company continues to seek capital through various means including the issuance of equity and/or debt. These material uncertainties cast substantial doubt as to the ability of the Company to meet its obligations as they come due and, accordingly, the appropriateness of the use of accounting principles applicable to a going concern. These consolidated financial statements do not include adjustments to amounts and classifications of assets and liabilities that might be necessary should the Company be unable to continue operations. Any such adjustments may be material.

In order to continue as a going concern and to meet its corporate objectives, the Company will require additional financing through debt or equity issuances or other available means. Although the Company has been successful in the past in obtaining financing, there is no assurance that it will be able to obtain adequate financing in the future or that such financing will be on terms advantageous to the Company.

These condensed interim consolidated financial statements, including comparatives, have been prepared in accordance with IAS 34, Interim Financial Reporting (“IAS 34”), as issued by the International Accounting Standards Board (“IASB”), and interpretations issued by the IFRS Interpretations Committee (“IFRIC”). Accordingly, they do not include all of the information required for full annual financial statements by IFRS Accounting Standards (“IFRS”) for complete financial statements for year-end reporting purposes.

These condensed interim consolidated financial statements should be read in conjunction with the Company’s audited financial statements for the year ended March 31, 2025, which have been prepared in accordance with IFRS as issued by IASB and IFRIC. These condensed interim financial statements are presented in Canadian dollars, which is also the Company’s functional currency.

These condensed interim consolidated financial statements have been prepared on a historical cost basis, except for financial instruments classified as financial instruments at fair value through profit and loss or fair value through other comprehensive loss, which are stated at their fair value. In addition, these condensed interim consolidated financial statements have been prepared using the accrual basis of accounting except for cash flow information.

The policies applied in these condensed interim consolidated financial statements are based on IFRS issued and effective as of June 30, 2025. The Board of Directors approved these condensed interim consolidated financial statements for issue on August 12, 2025.

These condensed interim consolidated financial statements include the financial statements of the Company and the entities controlled by the Company. Control exists when the Company has the power, directly or indirectly, to govern the financial and operating policies of an entity so as to obtain benefits from its activities. The financial statements of subsidiaries are included in the condensed interim consolidated financial statements from the date that control commences until the date that control ceases. All significant intercompany transactions and balances have been eliminated.

Rio Grande Resources Ltd (“Rio Grande”) was newly incorporated on July 19, 2024 for the purpose of the spin-out that was completed on January 31, 2025 (Note 16). At June 30, 2025, the Company owned 5,152,557 shares representing a 12.12% interest (March 31, 2025 – 19.95% interest) in Rio Grande (Note 4). Sierra Gold & Silver Ltd. (“Sierra”) was a wholly owned subsidiary of the Company and deconsolidated as a result of the completion of the spin-out during the year ended March 31, 2025.

The preparation of financial data is based on accounting principles and practices consistent with those used in the preparation of the audited consolidated financial statements as at March 31, 2025. These unaudited condensed interim consolidated financial statements should be read in conjunction with the Company’s audited financial statements for the year ended March 31, 2025, which have been prepared in accordance with IFRS as issued by IASB and IFRIC.

New accounting standards issued and effective

A number of new standards, and amendments to standards and interpretations, are not effective and have not been early adopted in preparing these consolidated financial statements.

Classification of Liabilities as Current or Non-current (Amendments to IAS 1) is effective for reporting periods beginning on or after January 1, 2024. The amendments to IAS1 provide a more general approach to the classification of liabilities based on the contractual arrangements in place at the reporting date. This amendment to standards resulted in the reclassification of the derivative warrant liability from non-current to current liability as described in Note 9.

Presentation and Disclosure in Financial Statements (IFRS 18) is effective for reporting periods beginning on or after January 1, 2027. IFRS 18 introduces three sets of new requirements to give investors more transparent and comparable information about companies’ financial performance for better investment decisions. The Company will be assessing the impact of adoption.

The Company is assessing the impact this new accounting standard may have on its condensed interim consolidated financial statements.

On January 31, 2025, as a result of the spin-out (Note 16) the Company received 5,152,557 shares of Rio Grande, a publicly traded company, representing a 19.95% interest in Rio Grande, at a fair value of $489,493. At March 31, 2025, 5,152,557 shares represented a 19.95% interest in Rio Grande. As a result of the share ownership in conjunction with other factors (including a common CEO and director) it was determined that the Company exercises significant influence over Rio Grande and has accounted for its investment in Rio Grande using the equity method.

At June 30, 2025, the Company owned 5,152,557 shares representing a 12.12% interest (March 31, 2025 – 19.95% interest) in Rio Grande.

Due to the reduction in share ownership and resulting significant influence, the shares were revalued and reclassified as marketable securities.

Any gains or losses are recorded in the condensed interim consolidated statements of income (loss) and comprehensive income (loss) as they relate to the issue of warrants recorded on the Company’s statement of financial position as a derivative liability measured at fair value through profit or loss.
