MTB METALS COMPLETES SALE OF NON-CORE ASSETS TO DOLLY VARDEN SILVER

Further to its news release dated May 15, 2025, MTB Metals Corp. has completed the sale of its interests in four exploration properties -- the American Creek property (consisting of the Mountain Boy, Silver Crown and Dorothy properties), the Theia property, the BA property and the Red Cliff property -- to Dolly Varden Silver Corp.

In return, MTB received 486,072 shares of Dolly Varden at a deemed value of $3.59 per consideration share and a net smelter return royalty of 1 per cent on all production from each of the Mountain Boy property, the BA property, the Theia property and the Silver Crown property. Dolly Varden has also assumed and stepped into MTB's obligations under MTB's option agreement to acquire the Dorothy property and MTB's joint venture agreement with respect to the Red Cliff property.

Dolly Varden is arm's length to MTB. No finders' fees or commissions are payable by the company in connection with the transaction. The transaction is subject to normal closing conditions, including the approval of the TSX Venture Exchange. In addition to the customary four-month hold on the shares to be received, MTB has agreed that it will provide notice to Dolly Varden if it plans to sell any of the consideration shares.

We seek Safe Harbor.
