First hole of the 2025 Phase 2 diamond drill program at Mount Polley returned a notable intercept: 11.0 m grading 4.43% Cu, 1.53 g/t Au and 41.7 g/t Ag.
Additional high‑grade intervals were intersected above and below the target zone, including 9.6 m at 3.71% Cu, 0.42 g/t Au and 9.89 g/t Ag.
The Phase 2 program comprises 3,718.3 m across nine holes; results from remaining holes are pending, with further drilling planned for 2026.

Hole WB‑25‑268 intercepts:
254.6–256.1 m (1.5 m): 3.58% Cu, 0.07 g/t Au, 13.6 g/t Ag
272.5–282.1 m (9.6 m): 3.71% Cu, 0.42 g/t Au, 9.89 g/t Ag
304.4–315.4 m (11.0 m): 4.43% Cu, 1.53 g/t Au, 41.7 g/t Ag (primary target interval)
414.6–420.7 m (6.1 m): 1.16% Cu, 0.36 g/t Au, 7.0 g/t Ag
467.5–500.0 m (32.5 m): 0.60% Cu, 0.28 g/t Au, 4.4 g/t Ag
542.5–557.5 m (15.0 m): 0.97% Cu, 0.63 g/t Au, 8.8 g/t Ag
Program scope: Phase 2 consists of nine drill holes totaling 3,718.3 m; this release covers only the first hole’s results.
Exploration objectives:
Test high‑grade zone beneath the Wight Pit (Green zone).
Expand and delineate higher‑gold C2 zone at depth.
Assess depth extension under the previously mined Bell Pit using new targeting techniques from the Springer Pit.
Historical context: Prior holes WB‑05‑189 and WB‑04‑179 intersected 15.0 m @ 3.1% Cu, 0.33 g/t Au, 20.1 g/t Ag and 12.4 m @ 6.7% Cu, 3.65 g/t Au, 44.8 g/t Ag respectively.
Resource reference: Martel zone underground indicated resource (as of Jan 1 2025) – 2.272 M tonnes at 1.14% Cu, 0.30 g/t Au, 7.20 g/t Ag (57.3 M lb Cu, 22 k oz Au, 526 k oz Ag).
