The technical report was prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves adopted May 19, 2014, and in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects, and supports the disclosure made by the company in its Oct. 10, 2023, news release announcing the updated mineral resource estimate.

Highlights:

• The updated MRE contains a total of 570,000 ounces of gold and 47.74 million ounces of silver or 100.04 Moz of silver equivalent, which is a 135-per-cent increase over the maiden resource estimate for Tonopah West included in the technical report dated effective April 28, 2022.
• At a 200 gram per tonne AgEq cut-off, the average grade of the inferred mineral resource is 508.5 g/t AgEq, which is a 14-per-cent increase over the maiden MRE.
