Vancouver, British Columbia--(Newsfile Corp. - September 25, 2024) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") announces 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, USA, and extends northward for over 5,000 ft (1.5km) to the north, to test for the presence of a porphyry copper deposit.

Bayhorse plans to drill from 230 ft (70m) 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 (Line 1030, Figure 1) 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% Silver, 17% 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 1320 (450 m) feet 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.
