BLUE MOON CONSOLIDATES SPRINGER TUNGSTEN CLAIMS WITH ACQUISITION OF CLAIMS FROM GOLDPLAY LLC AND A PRIVATE PARTY

Blue Moon Metals Inc. has entered into an agreement to acquire certain claims adjacent to the company's Springer mine, located in Pershing county, Nevada, from GoldPlay LLC and Robert Schafer, for consideration of 188,199 common shares of Blue Moon, $1-million (U.S.) cash and a sliding-scale gross revenue royalty (GRR) on the concessions.

Christian Kargl-Simard, chief executive officer of Blue Moon, states: "Following the acquisition of the Springer mine and processing plant that closed on Feb. 10, 2026 (see press releases from Oct. 14, 2025, and Feb. 10, 2026), this acquisition bolsters our land position and strategically consolidates claims around the mine. The company controls the district of the historical claims around the Springer tungsten deposit."

The claims

The claims consist of nine unpatented mineral claims. The claims cover a portion of some historically identified veins, including the Stank deposit, the O'Byrne deposits and a portion of the Sutton deposit, and have seen high-grade tungsten trioxide drill results such as 1.0 metre at 3.95 per cent WO3 in SU-43.

Springer geology

At the Springer mine, skarn formation and the tungsten mineralization are associated with the emplacement of the Springer stock and the nearby stocks. Tungsten-bearing calc-silicate assemblages have been formed by contact metasomatism following the intrusion of the Springer stock. The early stage of skarn formation is characterized by very high temperatures. During that stage, tungsten (scheelite), pyrite, chalcopyrite and molybdenite are emplaced proximal to the stock.

Transaction terms

Blue Moon is acquiring 100 per cent of the claims free and clear of all other encumbrances for the following consideration:

• Tthe issuance by Blue Moon to the sellers of 188,199 common shares of Blue Moon;
• $1-million (U.S.) in cash;
• A sliding-scale GRR, payable on mineral production on the claims, and subject to an option in favour of Blue Moon to buy down the GRR to 1.5 per cent for a period of three years for a cash payment of $2.0-million (U.S.).

Key condition precedent to completion of the acquisition is TSX Venture Exchange approval. A purchase and sale agreement has been executed by the parties on April 27, 2026, and completion is expected to happen by early May. No finders' fees are being paid on this acquisition.
