current Mineral Resource, on-strike and below the proposed open pits, indicating areas for potential

resource expansion. Additional Resource expansion potential also exists on several geologist-defined

drill targets within the Hasbrouck Gold Project mineral property holdings.

The Hasbrouck Gold Project demonstrates a high sensitivity to the price of gold, as shown in the

following sensitivity table from the 2023 Technical Report (as defined below):

Note to US Investors

This news release has been prepared in accordance wi th the requirements of the securities laws in

effect in Canada, which differ from the requirements of United States securities laws. The terms

“Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are defined in and

required to be disclosed by NI 43 -101. However, these terms are not defined terms under SEC S-K

1300 and are normally not permitted to be used in reports and registration statements filed with the

SEC. In addition, the terms “ Mineral Reserve ”, “Probable Mineral Reserve ” and “Proven Mineral

Reserve” are also defined in NI43-101 and not S-K 1300. Investors are cautioned not to assume that

all or any part of an “Indicated Mineral Resource” or “Inferred Mineral Resource” will ever be upgraded

to a higher category or converted into Mineral Reserves in accordance with S-K 1300. “Inferred Mineral

Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their

economic and legal feasibility. Under Canadian rules, estimates of Inferred Mineral Resources may

not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned

not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally

mineable. Disclosure of “contained ounces” in a Mineral Resource is permitted disclosure under

Canadian regulations; however, the SEC normally only permits issuers to report mineralization that

does not constitute “ Reserves” by SEC S-K 1300 standards as in-place tonnage and grade without

reference to unit measures. Accordingly, information contained in this News Relea se contain s

descriptions of the Company’s mineral deposits that may not be comparable to similar information

made public by U.S. companies subject to the reporting and disclosure requirements under the United

States federal securities laws and the rules and regulations thereunder.
