BAYHORSE SILVER ANNOUNCES DRILL PROGRAM ON BAYHORSE MINE VTEM ANOMALY FOR POTENTIAL PORPHYRY COPPER TARGET

Bayhorse Silver Inc. has begun an underground diamond drill program to drill the large low-resistivity anomaly that extends from beneath the company's silver-/copper-rich Bayhorse silver mine in Oregon, United States, and extends northward for over 5,000 feet (ft) (1.5 kilometres (km)) to the north, to test for the presence of a porphyry copper deposit.

Bayhorse plans to drill from 230 ft (70 metres (m)) inside the underground workings into the large low-resistivity anomaly at 755 ft (229 m) beneath the silver-/copper-rich bearing rhyolite at Bayhorse silver mine to test for the presence of a porphyry copper deposit. With a calculated vertical extent of 330 ft (100 m), this large anomaly (BHS2024-05) lies at the northwest corner of the VTEM geophysical survey and is open to the north beyond the VTEM survey northern boundary.

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 pe cent silver and 17 per cent copper (BHS2014-01) while gold values up to 10 g/t have been reported from historical mining (Silver King Mines, 1984).

A downhole geophysics program over an underground strike length of over 1,320 ft (450 m) using the existing underground drill holes, and including the new drill holes, is planned upon completion of this drill program to gain a clearer picture of the mineralization profile of the Bayhorse mine.

This exploration model is based largely on Hercules Metals' recently discovered porphyry copper deposit underlying historic silver mines in the Cuddy Mountains district approximately 45 kilometres 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.

Bayhorse chief executive officer Graeme O'Neill comments: "The low-resistivity/high-conductivity anomaly that we are targeting is in very close proximity to the Bayhorse underground working and appears to extend from approximately 550 ft (166 m) beneath the mine workings to depth of approximately 1,020 ft (309 m) for a 470 ft (142 m) vertical extent, a width of 350 ft and a calculated strike length of 550 ft (151 m). The Hercules porphyry copper discovery has been made at approximately 450 m (1,485 ft) level below grade."
