The Registrant is a “foreign private issuer” as defined in Rule 3b-4 under the Exchange Act. Equity securities of the Registrant are accordingly exempt from Sections 14(a), 14(b), 14(c), and 14(f) of the Exchange Act pursuant to Rule 3a12-3 thereunder. Furthermore, as a Canadian issuer, insiders of the Registrant are also exempt from Section 16 of the Exchange Act.

Effective October 31, 2025, the Registrant changed its fiscal year end from September 30 to December 31. This Annual Report on Form 40-F contains (i) the audited consolidated financial statements of the Registrant for the fifteen months ended December 31, 2025 and for the fiscal year ended September 30, 2024, including the report of the independent auditor with respect thereto, (ii) the Registrant’s Management’s Discussion and Analysis for the fifteen months ended December 31, 2025, and (iii) the Registrant’s Annual Information Form for the fifteen months ended December 31, 2025.

Unless otherwise indicated, all mineral resource and mineral reserve estimates included in the documents incorporated by reference into this Annual Report on Form 40-F have been prepared in accordance with Canadian National Instrument 43-101 (“NI 43-101”) and the Canadian Institute of Mining and Metallurgy Classification System. NI 43-101 is a rule developed by the Canadian securities administrators, which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ from the requirements of the United States Securities and Exchange Commission (the “SEC”). Accordingly, mineral resource and mineral reserve estimates, and other scientific and technical information, contained in the documents incorporated by reference into this Annual Report on Form 40-F may not be comparable to similar information disclosed by U.S. companies.

Unless otherwise indicated, all dollar amounts in this Annual Report on Form 40-F are in United States dollars. The exchange rate of United States dollars into Canadian dollars, on December 31, 2025, based upon historical rates published by the Bank of Canada, was U.S.$1.00 = C$1.37.
