Vancouver, August 14, 2020 - West Vault Mining Inc. (TSXV: WVM) ("West Vault" or the "Company") is pleased to announce that it has completed the purchase of a 25% interest in the Hasbrouck gold project, located in Tonopah, Nevada (the "Hasbrouck Gold Project"), from Clover Nevada LLC, a wholly owned subsidiary of Waterton Precious Metals Fund II Cayman, LP ("Waterton"). West Vault has now consolidated 100% ownership of the Hasbrouck Gold Project. The Hasbrouck Gold Project, comprised of the planned Three Hills mining area and the nearby planned Hasbrouck Mine, hosts an estimated 762,000 ounces of proven and probable gold reserves and 10,569,000 ounces of proven and probable silver reserves (proven mineral reserves of 6,242,000 tons at a grade of 0.02 Au oz/ton plus 0.41 Ag oz/ton and probable mineral reserves of 39,028,000 tons at a grade of 0.016 Au oz/ton plus 0.205 Ag oz/ton). For details, see the "Technical Report and Updated Preliminary Feasibility Study: Hasbrouck and Three Hills Gold-Silver Project, Esmeralda County, Nevada" dated September 14, 2016 as filed on SEDAR under the Company's profile at www.sedar.com.

The Updated Preliminary Feasibility Study determined that the Hasbrouck Gold Project would be a low cost, open pit, heap leach extraction gold mine with modest estimated peak funding of US $47 million and average gold production of approximately 71,000 ounces at an AISC of approximately US $709 per ounce.

R. Michael Jones, P.Eng., CEO of West Vault said "We are very pleased to consolidate the 100% project interest in this advanced stage gold project, with good shareholder support at a time of increased interest in gold and gold mining." West Vault is focused on advancing the Hasbrouck Gold Project. The first pit and heap leach area at Three Hills has federal and state permits and Company is working towards completing full federal permitting for the second phase Hasbrouck Mine while keeping corporate G&A costs lean and efficient.

To acquire Waterton's interests the Company paid US $10.0 million in cash and issued 1.0 million common shares of West Vault to Waterton. The securities issued have a hold period of four months and one day from closing, expiring December 14, 2020. See further details in the Company's announcement of the transaction on July 22, 2020.

Cautionary Note to U.S. Investors Regarding the Use of Mining Terms

This press release has been prepared in accordance with the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all reserve estimates reported by the Company are in relation to a 2016 Updated Pre-Feasibility Study and have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the U.S. Securities and Exchange Commission (the "SEC") Industry Guide 7, and reserve information contained herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, "reserves" established under NI 43-101 standards may not qualify as "reserves" under U.S. standards. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. In addition, under U.S. standards, a "Final" or "Bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. Accordingly, information concerning mineral deposits set forth in this press release may not be comparable with information made public by companies that report in accordance with U.S. standards.
