Bayhorse Silver Mobilizes Drill to the Bayhorse Mine VTEM Anomaly for Drilling Potential Porphyry Copper Target

Vancouver, British Columbia--(Newsfile Corp. - November 20, 2024) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") announces the arrival of the underground diamond drill rig at the Bayhorse Silver Mine to drill the large low-resistivity anomaly that lies beneath the Company's silver/copper rich Bayhorse Silver Mine in Oregon, USA. The drilling operations will commence shortly.

Bayhorse plans to drill from 241 ft (73 m) inside from the Mine portal, at an elevation that is 703 m (2320 ft) above sea level, to the underground workings into the large low-resistivity anomaly that lies beneath the silver/copper rich bearing rhyolite at Bayhorse Silver Mine. Revised calculations indicate the anomaly has a vertical extent of 500 m (1650 ft) from 600 m (1980 ft) above sea level to 100 m (330 ft) above sea level and a width of up to 100 m (330 ft).

The Company anticipates intersecting the top of the anomaly 150 m (495 ft) down hole with a projected termination depth of 257 m (850 ft) at the east side of the anomaly, to test for the presence of a porphyry copper deposit.

Historic geological maps show the presence of a quartz porphyry around the Bayhorse Silver Mine workings.

In the sections image below, line 1040 lies directly beneath the diamond drill location, while line 1050 is 100m (330 ft) east of and just outside the underground workings.

The Bayhorse exploration model holds that the silver/copper rich mineralized rhyolite at the Bayhorse Silver Mine could have its source in underlying shallow granites that may be conductive porphyry copper bodies as reflected by the low-resistivity anomalies (Conway, 2024). The highest silver/copper grade identified at the Bayhorse Silver Mine is 15% Silver, 17% Copper (BHS2014-01) while gold values up to 10 g/t have been reported from historical mining (Silver King Mines 1984).

This exploration model is based largely on Hercules Metals' recently discovered porphyry copper deposit underlying historic silver mines in the Cuddy Mountains district some 44 kilometers northeast of Bayhorse/Pegasus. There the porphyry copper has a low-resistivity signature thus, it may be inferred that porphyry copper deposits could be present at Bayhorse/Pegasus and also at the Mineral district 20 km (12miles) to the north of the Bayhorse. (BHS2024-18).

Bayhorse CEO, Graeme O'Neill, comments "the low-resistivity/high-conductivity anomaly that we are targeting starts 150 m (495 feet) below the portal to the Bayhorse underground workings, has a calculated depth to its bottom of between 400 and 500 meters (1312 - 1640 feet) and extends over one mile (1.6km) to the north. Drill setup underground is underway, with drilling commencement targeted on completion of setup. Each of the first two holes have a targeted depth of 260 meters (850 feet).
