Bayhorse extends known Ag mineralization at Oregon mine

Executive Summary

• Bayhorse Silver announced a significant extension of known silver mineralization at its Bayhorse mine to >400 m E‑W and 560 m N‑S, with a vertical extent of 91 m.
• Two new high‑grade mineralized zones were intersected in RC holes MW‑1 and MW‑3, confirming additional potential resources adjacent to historic mined areas.
• The company expects the expanded drill program to increase its NI 43‑101 inferred resource (currently 292,300 t @ 21.65 oz/t for 6.3 Moz Ag) and may identify porphyry copper mineralization on the nearby Pegasus project.

Key Details

• Extent of Mineralization: >400 m east‑west, 560 m north‑south, vertical extent 91 m.
• New Zone 1 (RC hole MW‑1):
• Hole length: 725 ft (221 m) vertical, collared at 862 m ASL, located 365 m SW of mine portal.
• Two mineralized zones intersected at depths of 310 ft and 380 ft.
• New Zone 2 (RC hole MW‑3):
• Hole length: 220 ft (67 m) vertical, collared 36.6 m SE of portal at 713 m ASL.
• Mineralized zone intersected ~30 m (100 ft) below the hole, near a previously reported 917 g/t (29.6 oz/t) intersection.
• Historical Context: New zones lie within 198 m (650 ft) of the historic Goldilocks area where ore up to 100 oz/t was mined in 1984.
• Assay Protocols: Fire‑assays by Christopherson Inc.; multi‑element analysis by Paragon Geochemical; QA/QC includes blanks, standards every 20 samples, and duplicates.
• Qualified Person: Mark Abrams, AIPG (director) reviewed and approved technical content.
• Future Plans: Upcoming IP survey to extend mineralization onto the adjacent Pegasus project (~760 m apart, ~9 km²) and explore potential porphyry copper targets.

Notable Quotes

“By significantly extending the known areas of high‑grade silver mineralization, further drill testing and sampling may lead to an increase in the company’s NI 43‑101 inferred resource… We are looking to extend the Bayhorse silver mineralization onto our adjacent Pegasus project, with our upcoming IP survey that may also identify the presence of potential porphyry copper mineralization.” – Graeme O’Neill, CEO, Bayhorse Silver Inc.
