Bayhorse Silver Pegasus Silver/Copper Project IP Survey Parameters

Rhea-AI Summary

Bayhorse Silver (OTCQB: BHSIF) has confirmed parameters for an upcoming IP survey at its Pegasus Silver/Copper Project in Idaho, located 600m east of the Bayhorse Silver Mine. The survey follows a VTEM Survey and geological mapping program that revealed significant geophysical anomalies and copper oxide surface showings.

The survey will cover over one-third of the Pegasus property, targeting three potential mineralization types: epithermal high-grade silver extension, copper porphyry, and skarn hosted mineralization with potential gold content. Historical data shows up to 10 g/t gold present at the adjacent Bayhorse Silver Mine.

The company also highlighted potential benefits from President Trump's recently passed Big Beautiful Bill (BBB), which aims to fast-track mining project permits and provide tax incentives for domestic mineral production.

Positive

• Property shows significant geophysical anomalies and copper oxide surface showings
• Historical data indicates high gold content (up to 10 g/t) at adjacent mine
• Company could benefit from new BBB legislation for fast-track permitting and tax incentives
• Project located in mining-friendly jurisdiction of Idaho

Negative

• Project area is virtually unexplored
• Mineralization targets are still hypothetical and require confirmation

Vancouver, British Columbia--(Newsfile Corp. - July 9, 2025) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") announces that as a result of a comprehensive review by the Company's geological consultants and SJ Geophysics, it has confirmed the parameters for the upcoming IP survey at the Company's Pegasus Silver/Copper Project, that lies 600 m (1,970 ft) east of the silver rich Bayhorse Silver Mine in the State of Idaho.

Following the recent VTEM Survey and subsequent geological mapping program, the Company's senior geologists believe the Pegasus ground presents some exciting exploration possibilities. In this virtually unexplored area, there are some significant geophysical anomalies as well as surface Cu oxide showings that suggests the following possible targets that will be covered by the IP Survey:

a) An extension of the epithermal high-grade silver mineralization similar to the Bayhorse Mine.
b) A Cu porphyry.
c) Skarn hosted mineralization formed in some of the limestone-marbles identified during the mapping program with potential gold mineralization.

The planned IP survey area covers over one-third of the Pegasus property along the strike of the low-resistivity zone, the low magnetic zone where there are rhyolite outcrops, and the area of possible skarn hosted mineralization. It is intended to test the hypothesis that the silver bearing epithermal structures at the Bayhorse Silver Mine extend across the Snake River into the mining friendly jurisdiction of Idaho in sufficient quantity to allow for consideration for discovery of a second Silver Mine.

Skarn deposits are economically significant, often hosting valuable metals like copper and gold. Up to 10 g/t gold is present at the adjacent silver rich Bayhorse Silver Mine (Silver King Mines, 1984). Gold showings were identified at the north end of the Pegasus claims during the recent geological mapping program, which gives the geological team confidence that further gold mineralization will be identified, along with the silver and copper.

Bayhorse CEO, Graeme O'Neill, comments on the recent passing of President Trump's Big Beautiful Bill ("BBB"), "Its stated goals are to Fast-Track permitting for mining projects, provide tax incentives for mining & processing, and encourage domestic production and processing of critical minerals through tax relief and royalty holidays. Significantly for Bayhorse, with a fully permitted processing facility in mining friendly Idaho, it also provides mandates for domestic processing & refining." O'Neill further comments, in his opinion, "Bayhorse Silver should be a big beneficiary from fast tracking the permitting process, and with "BBBs" further goal of broadening the list of minerals designated as "critical" for national security and economic stability, the BBB should bring much needed attention to the mining and exploration sector."
