Sterling Metals begins phase 2 drilling at Soo
Executive Summary
- Sterling Metals has launched a Phase 2 drill program (3,000‑5,000 m) to test extensions of the GFP porphyry dike swarm and near‑surface anomalies identified in Phase 1.
- Historic drill holes continue to return significant copper–gold–silver mineralization (e.g., MJ‑01: 359.6 m @ 0.26% Cu, 0.011% Mo, 0.05 g/t Au, 1.4 g/t Ag).
- Expanded soil‑sampling, prospecting, and new geophysical inversions have identified additional targets across a 30‑km mineralized system, supporting a larger feeder‑system model for the GFP porphyry.
Key Details
- Phase 2 Drill Plan: 3,000–5,000 m total length targeting four primary zones:
- Downdip extension of GFP porphyry dike swarm (all MJ series holes intersected GFP porphyry).
- Near‑surface expression of ZTEM resistivity‑low anomaly linked to feeder system.
- Depth extension of the Richards breccia (historic strong mineralization).
-
Near‑surface resistivity lows along a 1.5 km corridor.
-
Notable Historic Intercepts:
- MJ‑01: 359.6 m @ 0.26% Cu, 0.011% Mo, 0.05 g/t Au, 1.4 g/t Ag.
- R2301: 38.63 m @ 1.06% Cu, 0.07 g/t Au, 3.55 g/t Ag (Richards breccia).
-
R2304: 50.17 m @ 0.88% Cu, 4.56 g/t Ag, 0.09 g/t Au (Richards breccia).
-
Soil‑Sampling & Prospecting Expansion:
- Copper‑in‑soil anomaly now extends >5 km southwest; new anomalies identified 3 km NW of drill area and 5 km from historic Tribag mine.
-
New bornite and chalcopyrite outcrops discovered ~3 km from Phase 2 target zone.
-
Geophysical Work:
- Completed new inversions on a 23‑km² induced polarization/resistivity survey.
-
Property‑wide magnetic and drone magnetic surveys refined the model, indicating multiple GFP porphyry “fingers” or splays within current targets.
-
Logistics & Infrastructure:
-
Project located in a top‑10 global mining jurisdiction; ~1 h from Sault Ste. Marie, 20 km from rail line with direct deep‑water port access, and 20 min from the Trans‑Canada Highway.
-
Technical Review: Jeremy Niemi, P.Geo., SVP Exploration & Evaluation, has reviewed and approved all technical information.
