Sterling Metals CEO Mathew Wilson told Mining Stock Daily that the September 2025 MEPS discovery at the Soo Copper Project near Sault Ste. Marie — which returned 265 metres grading 1.05% copper equivalent — is not an isolated hole, but the center point of a 30-kilometre mineralized corridor bookended by two historic copper mines. The company launched a 20,000-metre drill program intended to establish the footprint and grade of that mineralized area.
