This Report uses the terms “mineral resources”, “indicated mineral resources” and “inferred mineral resources” as such terms are defined under Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”). NI 43-101 is a rule developed by the Canadian Securities Administrators, which establishes standards for all public disclosure a Canadian issuer makes of scientific and technical information concerning mineral projects.

On October 31, 2018, the SEC adopted new mining disclosure rules (“S-K 1300”) that are more closely aligned with current industry and global regulatory practices and standards, including NI 43-101, with which we comply because we are also a “reporting issuer” under Canadian securities laws. While S-K 1300 is more closely aligned with NI 43-101 than the prior mining disclosure rules of the Securities and Exchange Commission, there are some differences. Accordingly, there is no assurance any mineral resources that the Company may report as “indicated mineral resources” and “inferred mineral resources” under NI 43-101 will be the same as the reserve or resource estimates prepared under S-K 1300. Investors should not assume that any part or all of indicated mineral resources or inferred mineral resources will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to their existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any “indicated mineral resources” or “inferred mineral resources” on the Company’s projects are or will be economically or legally mineable. Further, “inferred resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of the inferred resources exist. In accordance with Canadian rules, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.

It should be noted that the Company filed technical reports prepared in accordance with S-K 1300 as Exhibits 96.1 and 96.2 to its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the Securities and Exchange Commission on March 20, 2025.
