Except for the statements of historical fact contained herein and, in the exhibits hereto, the information presented in this Annual Report on Form 40-F, including the exhibits hereto (collectively, the “Form 40-F”) constitutes forward-looking information within the meaning of applicable securities laws (collectively, “Forward-Looking Information”) concerning the business, operations, plans and financial performance and condition of the Registrant. Often, but not always, Forward-Looking Information can be identified by words such as “plans”, “expects”, “may”, “should”, “could”, “will”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, “believes”, or variations including negative variations thereof of such words and phrases that refer to certain actions, events or results that may, could, would, might or will occur or be taken or achieved.

Forward-Looking Information involves known and unknown risks, uncertainties and other factors which may cause the actual plans, results, performance or achievements of the Registrant to differ materially from any future plans, results, performance or achievements expressed or implied by the Forward-Looking Information. Such factors include, among others: the risks relating to mineral exploration, development and operations; industry conditions; uncertainty of mineral resource and mineral estimates; negative operating cash flows; financing risks and additional financing; the ability of the Corporation to meet its financial obligations as they become due; actual operating cash flows, operating costs, free cash flows, total cash, transaction costs, and administrative costs of the Registrant differing materially from those anticipated; failure to obtain licenses, approvals or permitting in a timely manner (or at all); risks relating to project infrastructure requirements and anticipated processing methods, exploration expenditures differing materially from those anticipated; changes in project parameters; the possibility of project cost overruns or unanticipated costs and expenses; accidents, labour disputes, community and stakeholder protests and other risks of the mining industry risks relating to foreign operations and enforcement of judgements; risks related to partnership or other joint operations; actual results of current exploration activities; variations in mineral resources, mineral production, grades or recovery rates or optimization efforts; uninsured risks, including, but not limited to, pollution, cave-ins or hazards for which insurance cannot be obtained; regulatory changes, defects in title; availability or integration of personnel, materials and equipment; inability to recruit or retain management and key personnel; adequacy and access to required infrastructure, equipment and supplies; unanticipated environmental impacts on operations; market prices; operating risks associated with the operations or an expansion of the operations; cybersecurity threats and technological risks; foreign operations risk; impact of any litigation; risks relating to significant shareholder control; dilution due to future equity financings; fluctuations in precious or base metal prices and currency exchange rates; uncertainty relating to future production and cash resources; anticipated timing of events, developments and milestones at the Registrant’s properties; inflation; adverse changes to market, political and general economic conditions or laws, rules and regulations applicable to the Registrant; risks relating to climate change; outbreak of diseases and public health crises; risks relating to any imposition of tariffs or other trade restrictions; risk of an undiscovered defect in title or other adverse claim; factors discussed under the heading “Risk Factors”; and other risks, including those risks set out in the continuous disclosure documents of the Registrant, which are available on SEDAR+ (www.sedarplus.ca) and on EDGAR (www.sec.gov) under the Registrant’s issuer profiles.

In addition, Forward-Looking Information in this Form 40-F is based on certain assumptions and involves risks related to the business of the Registrant. Forward-Looking Information contained in this Form 40-F is based on certain assumptions, including, but are not limited to, interest and exchange rates; the price of gold, silver and other metals; competitive conditions in the mining industry; title to mineral properties; financing and funding requirements; general economic, political and market conditions; and changes in laws, rules and regulations applicable to the Registrant.

Although the Registrant has attempted to identify important factors that could cause plans, actions, events or results to differ materially from those described in Forward-Looking Information in this Form 40-F, there may be other factors that cause plans, actions, events or results not to be as anticipated, estimated or intended. There is no assurance that such statements will prove to be accurate as actual plans, results and future events could differ materially from those anticipated in such statements or information. Accordingly, readers should not place undue reliance on Forward-Looking Information in this Form 40-F. All of the Forward-Looking Information in this Form 40-F is qualified by these cautionary statements.

Certain Forward-Looking Information and other information contained in this Form 40-F concerning the mining industry and the expectations of the Registrant concerning the mining industry and the Registrant are based on estimates prepared by the Registrant using data from publicly available industry sources as well as from market research and industry analysis and on assumptions based on data and knowledge of this industry which the Registrant believes to be reasonable. However, although generally indicative of relative market positions, market shares and performance characteristics, this data is inherently imprecise. While the Registrant is not aware of any misstatement regarding any industry data presented in this Form 40-F, the mining industry involves risks and uncertainties that are subject to change based on various factors.

Readers are cautioned not to place undue reliance on Forward-Looking Information. The Registrant does not undertake any obligation to update any of the Forward-Looking Information in this Form 40-F, except as required by law.

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, which are filed with this Form 40-F in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board, and the audit is subject to auditing and independence standards in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”) and Public Company Accounting Oversight Board.

The Registrant is subject to the reporting requirements of the applicable Canadian securities laws, and as a result reports information regarding mineral properties, mineralization and estimates of mineral reserves and mineral resources in accordance with Canadian reporting requirements, which are governed by Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects. As such, the information incorporated by reference in this Form 40-F concerning mineral properties, mineralization and estimates of mineral reserves and mineral resources is not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the Commission.
