Bayhorse Silver Inc, (TSXV: BHS,OTC:BHSIF) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") has begun mobilization to its Pegasus Porphyry CopperSilver prospect and its silver-copper-antimony rich Bayhorse Silver Mine in Oregon, USA for an IP survey to be conducted by SJ Geophysics, commencing October 11, 2025.
The Pegasus IP geophysical survey will cover the large low-resistivity anomalies identified in the Company's airborne VTEM survey conducted in January 2024 to better identify drill targets and depths into the anomalies. The anomalous area extends over 1.6 km in length and the VTEM results indicate a vertical extent of at least 550 m (1804 feet). The survey should discriminate between rocks that conduct electrical current and those that don't and can also measure the chargeability of a rock which is its ability to hold a charge. Rocks with common but disconnected zones of sulfides have the largest chargeability responses and massive sulphides and copper porphyry are ideal chargeability targets.
The Bayhorse IP survey will extend the area of the original survey to cover the west side of the Bayhorse Mine. The first survey under the eastern area identified a number of IP anomalies under the Bayhorse Mine access road. where downhole silver assay results from drill hole WM2 were intersected, at an interval depth of from 22 to 33.5 m (72 ft to 110 ft) from surface. The most significant silver assay reported (BHS2025-12) was for two samples from the first 1.5 m (5f ft) of the intersection - 1,486.74 g/t (47.8 opt) and 719 g/t (23.12 opt) for an average 1104 g/t (35.46 opt) within a 10.6 meters (35 ft) zone of silver mineralization. A second 1.5m (5 ft) silver intersection within the mineralized zone assayed 770 g/t (23.12 opt), with the 3 m (10 ft) intersection averaging 937 g/t (30.12 oz/t) silver. (full assay results are shown in table, below)
The Bayhorse exploration model holds that the silver-copper-antimony rich mineralization at the Bayhorse Silver Mine extends across to the adjacent Pegasus porphyry copper prospect and could have its source in an underlying shallow pluton(s) that may host porphyry copper mineralization similar to what Hercules Metals has reported 40 km north of the Bayhorse Silver Mine.

Significant copper credits are associated with silver at the Bayhorse Silver Mine. In 2020, the Company conducted a metallurgical test on a 200 kg mined sample and passed it through the Company's Ore-Sorter that gave a 5 kg Ore-Sorter select sample with a head grade of 985 g/t (28.8 oz/t) silver, 1.16% copper and 1.87% zinc, The testing achieved silver/copper concentrate recoveries of 86.7%, resulting in a silver grade of 9,700 g/t and 10% copper. The dominant mineralization at the Bayhorse mine is Tetrahedrite (BHS2020-12) that has a significant antimony content.
Bayhorse CEO, Graeme O'Neill, Director Christos Doulis and Geologist and Director Mark Abrams will be at the Bayhorse Mine and Pegasus Project during the IP survey, and CEO Graeme O'Neill and Director Mark Abrams will be attending the Idaho Mining Conference, Boise, Idaho, October 27 and 28, 2025.
Cautionary statement
The Company is not basing any decision to produce on a feasibility study of mineral reserves demonstrating economic and technical viability and advises there is an increased uncertainty and specific economic and technical risk of failure with any production decision. These risks include, but are not limited to, (i) a drop in price of commodities produced, namely silver, copper, lead and zinc, from the pricing used to make a production decision; (ii) failure of grades of the produced material to fall within the parameters used to make the production decision; (iii) an increase in mining costs due to changes within the mine during development and mining procedures; and (iv) metallurgical recovery changes that cannot be anticipated at the time of production.
