Item 7.01. | Regulation FD Disclosure.

On February 13, 2024, the Company issued a news release discussing certain exploration activities during the fourth quarter of 2023 and reporting reserve and resource estimates as of December 31, 2023. A copy of the Company’s news release is attached as Exhibit 99.1 to this Current Report and is incorporated herein by reference.

Cautionary Statements to Investors on Reserves and Resources

The news release furnished herewith uses the terms “mineral resources,” “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources.” Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically, and an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve. We report reserves and resources under the SEC’s mining disclosure rules (“S-K 1300”) and Canada’s because we are also a “reporting issuer” under Canadian securities laws. Unless otherwise indicated, all resource and reserve estimates contained in the news release included as an exhibit to this Current Report have been prepared in accordance with S-K 1300 as well as NI 43-101.

In accordance with General Instruction B.2 of Form 8-K, the information in Item 7.01 is being furnished and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any of the Company’s filings or other documents filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
