New Drilling Results Achieved at the Poly Hill Copper-Gold Mine in Canada

According to a report on Mining.com, Imperial Metals has achieved significant results in diamond drilling at the Mount Polley mine in south-central British Columbia, Canada.

The 2025 drilling program focuses on the C2 ore block, which is adjacent to the south of the active Cariboo open-pit mine. The ongoing work aims to fill gaps in historical drilling data to support the expansion design of the pit and to verify the presence of deep high-grade ore bodies.

Preliminary drilling intersected 152.5 meters of ore at a depth of 282.5 meters, with a copper grade of 0.46% and a gold grade of 0.97 g/mt. Another intersection at 285 meters deep revealed 85 meters of ore with a copper grade of 0.67% and a gold grade of 1.56 g/mt.

Two other holes also encountered significant mineralization, with gold grades as high as 1.1 g/mt, copper grades of 0.79%, and substantial thicknesses.

Three years ago, the company resumed production of copper and gold at the Mount Polley copper mine.
