News Release No. 135-2021

WEST VAULT ENTERS US $7.3 MILLION GOLD AND SILVER STREAM

AGREEMENT WITH SPROTT

VANCOUVER, BRITISH COLUMBIA, February 22, 2021 – West Vault Mining Inc. (W VM:TSXV,

OTCQX:WVMDF) (“West Vault” or the “Company”) announces the execution of a definitive Purchase

and Sale Agreement (the “Stream Agreement”) between the Company and Sprott Private Resource

Streaming and Royalty Corp. (“Sprott”) for 1.41% of all refined gold and silver (the “1.41% Stream”)

to be produced for the life of mine from the Hasbrouck Gold Project, located southwest of Tonopah,

Nevada and comprised of the 100% owned Hasbrouck property, Three Hills property and the Hill of

Gold property (together the “Hasbrouck Gold Project”).

Under the terms of the Stream Agreement , Sprott is to pay the Company (a) an advance purchase

deposit of US $6.0 million (the “Advance Deposit”); and (b) an additional deposit of US $1.0 million

(the “Additional Deposit” and collectively with the Advance Deposit, the “Deposit”) within 10 days of

the Company announcing a Board-approved construction decision for the Hasbrouck Gold P roject.

Sprott may then elect to add the Hill of Gold property to the property covered by the Stream Agreement

by paying to the Company (c) a final amount, to be added to the Deposit, of US $300,000 within 60

days of paying the Additional Deposit. A cash transfer price payable to the Company upon delivery of

refined gold and silver to Sprott has been set at 20% of the market value per ounce of metal, as quoted

by the London Bullion Market Association on the date of delivery . The balance of the market value

per ounce will be applied as a credit against the Deposit until the Deposit is fully utilized. Thereafter

the price of the metals paid to the Company will be 20% of the market value thereof.

The permitted Hasbrouck Gold Project is one of only a few shovel-ready gold projects in the US South-

west, and not including the Hill of Gold property, hosts an estimated 762,000 ounces of Proven and

Probable gold Reserves1 and 10,569,000 ounces of Proven and Probable silver Reserves1. At a gold

price of US $1,800, an independent Pre -feasibility Study completed in 20161 (the “ 2016 PFS”)

estimated an after-tax IRR of 92% and a US $295 Million NPV(5). The Company believes additional

mineral resources may be delineated adjacent to the known deposit areas by further exploration drilling

during construction and operation.

In May 2017, the Company purchased a n existing 1.1% Net Smelter Return Royalty (the “ Acquired

Royalty”) over the Hasbrouck Gold Project from Newmont Mining Corporation. The 2016 PFS

assumed the Acquired Royalty was owned by a third party, resulting in an expense and a reduction to

the project’s estimated NPV. The 1.41% Stream is calculated to approximately offset the cost to the

project as if the Acquired Royalty was sold to a third party. As a result, the 2016 PFS modelled NPV

has not materially changed and the 1.41% Stream proceeds to be received by the Company are

effectively an addition to the project’s NPV as estimated in the 2016 PFS.

Federal permits issued by the Bureau of Land Management are now in place for both the Three Hills

Mine and the Hasbrouck Mine. State permits are in place for the Three Hills Mine and will be

processed in due course for the Hasbrouck Mine. The Company is currently working to amend its

existing permits at the Three Hills Mine to allow mineralized material mined at the Hill of Gold property

to be placed and processed on the planned heap leach pad for the Three Hills Mine. The Hill of Gold

property hosts a non -current historical inferred resource (see the Company’s news release dated

February 2, 2021). A qualified person has not done sufficient work to classify this historical estimate

as current mineral resources or mineral reserves, and the Company is not treating the historical

estimate as current mineral resources or mineral reserves.

Closing of the Stream Agreement is subject to the satisfaction of closing conditions, including receipt

of regulatory approval.

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

This press release has been prepared in a ccordance 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 establis hes 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.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the

policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this

release.
