Vancouver, British Columbia-- June 11, 2025 - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") reports that recent drilling, and a review of drill holes MW2, and MW3 has confirmed Bayhorse silver mineralization is epithermal in nature and has been identified as extending 150 meters beyond the most westerly extent of the existing underground workings for a total east-west strike length of nearly 500 meters (1640 ft). (BHS2024.14)

Underground diamond drilling is planned from drilling stations in the most westerly extent of the historic main east-west haulage way into the new high grade "Drift Zone" that lies parallel to, and 20 to 30 meters (65-100 ft) to the south of the haulage way. The new Drift Zone is estimated to be a minimum 10 meters in width, similar to other mined zones in the Bayhorse Mine.

Three panel samples were taken across the westerly face of the Drift Zone. These samples graded*:192.35 oz/t (5,984.72 g/t) silver and 10.7% copper., 50.88 oz/t (1,582.54 g/t) silver and 4.51% copper, and 3.3 oz/t (102.64 g/t) silver and 1.72% copper. (*surface samples are considered select samples and may not represent true values). (BHS2024-11)

The new "Drift Zone" was discovered when driving the new access tunnel to safely access the historic Big Dog high grade zone. Sampling identified silver mineralization on its south wall and the new drift was started extending to the west and south of the Big Dog access tunnel.
