Bayhorse mobilizes for IP surveys at Pegasus, Bayhorse

Executive Summary

• Bayhorse Silver has mobilized to commence an IP (induced polarization) geophysical survey of its Pegasus porphyry copper/silver prospect and the Bayhorse silver‑copper‑antimony mine, starting Oct. 11, 2025.
• The survey aims to refine drill targets within a 1.6 km anomaly identified by a Jan‑2024 VTEM airborne survey that shows a vertical extent of at least 550 m.
• High‑grade silver intercepts from prior drilling (up to 1,486.74 g/t Ag) are highlighted, supporting the exploration model linking the Bayhorse mine mineralization to underlying porphyry copper systems.

Key Details

• Survey Scope: IP survey by SJ Geophysics covering the Pegasus prospect anomaly and extending westward under the Bayhorse mine access road.
• Anomaly Dimensions: Horizontal length ~1.6 km; VTEM‑derived vertical extent ≥550 m (1,804 ft).
• Targeted Drill Targets: IP data will help discriminate conductive sulphide zones versus non‑conductive host rocks, focusing on chargeability responses indicative of massive sulphides and copper porphyry.
• Historical High‑Grade Intercepts:
• Hole WM2 intersected silver at 22–33.5 m depth; assay BHS2025‑12 returned 1,486.74 g/t (47.8 oz/t) and 719 g/t (23.12 oz/t) over the first 1.5 m, averaging 1,104 g/t (35.46 oz/t) across a 10.6 m zone.
• Adjacent 1.5 m interval assayed 770 g/t (23.12 oz/t); three‑meter composite averaged 937 g/t (30.12 oz/t).
• Exploration Model: Suggests the silver‑copper‑antimony mineralization at Bayhorse may extend into Pegasus and be sourced from a shallow pluton potentially hosting porphyry copper similar to nearby Hercules Metals discovery (~40 km north).
• Metallurgical Context: 2020 test on 200 kg mined sample yielded 985 g/t Ag, 1.16 % Cu, 1.87 % Zn in a 5 kg sorter‑select; concentrate recoveries of 86.7 % produced 9,700 g/t Ag and 10 % Cu, with tetrahedrite (BHS2020‑12) as dominant mineral containing notable antimony.
• Management Presence: CEO Graeme O’Neill, Director Christos Doulis, and Geologist/Director Mark Abrams will be onsite during the survey; O’Neill and Abrams to attend Idaho Mining Conference in Boise on Oct. 27–28, 2025.
