Sandy McVey, West Vault's CEO comments, "The current gold market appears to be generating greater interest in economically-robust gold projects. I am proud of our team's work in advancing the Hasbrouck Gold Project to construction-readiness. It takes many years of patient work to achieve a permitted, shovel-ready project in the best jurisdiction, and we now hope to benefit from being in the right place at the right time."

Investors have shown renewed interest in the Hasbrouck Gold Project since the Company published an economically-robust NI 43-101 Pre-Feasibility Study update in January 2023:

2023 Pre-Feasibility Study Highlights (2016 PFS at $1,275 gold in brackets)

The Hasbrouck Gold Project has a number of significant gold intercepts outside but proximal to the 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):

Non-IFRS Reporting Measures

"All-in Sustaining Costs" are not Performance Measures reported in accordance with International Financial Reporting Standards ("IFRS"). These performance measures are included because these statistics are key performance measures that management uses to monitor performance. Management uses these statistics to assess how the Project ranks against its peer projects and to assess the overall effectiveness and efficiency of the contemplated mining operations. These performance measures do not have a meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.

Disclaimer for Forward-Looking Information

This press release may contain forward-looking information or forward-looking statements (collectively "forward-looking information") within the meaning of applicable securities laws. Forward-looking information is typically identified by words such as: "will", "exploration potential", "economically robust", "high-quality development project", "high sensitivity to gold price", "progressively de-risking", "permitted, fully-construction-ready status", "construction-readiness", "shovel-ready project", "low-risk", "gold-in-ground", "well-understood", "minimal pre-strip", and similar expressions, and those, which, by their nature, refer to future events. All statements that are not statements of historical fact are forward-looking statements. Forward-looking statements in this news release include, without limitation, statements regarding the projected cost and economic performance of the Project based on the 2023 Technical Report, the Company's ability to obtain any additional permits required to commence and complete construction and perform operations, the Company's ability to obtain required funding on reasonable terms, and the potential identification, execution, and realization of accretive opportunities.

Note to US Investors

This news release has been prepared in accordance with 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 Release contains 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.
