DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Registrant is permitted, under a multijurisdictional disclosure system adopted by the United States, to prepare this report in accordance with Canadian disclosure requirements, which are different from those of the United States. The Registrant prepares its financial statements in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board, and the audit is conducted in accordance with Canadian generally accepted auditing standards. IFRS differs in certain respects from United States generally accepted accounting principles (“U.S. GAAP”) and from practices prescribed by the Securities and Exchange Commission (the “SEC”). Therefore, the Registrant’s financial statements filed with this Annual Report may not be comparable to financial statements prepared in accordance with U.S. GAAP. The Registrant’s mineral reserves and mineral resources have been calculated in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”), as required by Canadian securities regulatory authorities. Accordingly, mineral resource and mineral reserve estimates, and other scientific and technical information, in this Annual Report and incorporated by reference herein may not be comparable with information made public by United States companies subject to the SEC’s reporting and disclosure requirements.

CURRENCY

Unless otherwise indicated, all references to "$", "dollars" or "CAD" in this Annual Report refer to Canadian dollars, all references to "US$" or "USD" refer to United States dollars, and all references to "NOK" refer to Norwegian Krone. The exchange rate of Canadian dollars into United States dollars, on December 31, 2025, based upon the average daily exchange rate as quoted by the Bank of Canada, was US$1.00 = $1.3706.

DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this Annual Report, the Registrant carried out an evaluation, under the supervision of the Registrant’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Registrant’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Based upon that evaluation, the Registrant’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Annual Report, the Registrant’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Registrant in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) accumulated and communicated to the Registrant’s management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

While the Registrant’s principal executive officer and principal financial officer believe that the Registrant’s disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that the Registrant’s disclosure controls and procedures or internal control over financial reporting will prevent all errors or fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
