Sterling Metals Intersects 235.5m at 0.42% Cu and 0.042 g/t Au including 32.75m at 1.31% Cu and 0.11 g/t Au and Discovers New Bornite-Covellite Zone
Sterling Metals transitions from "needle-in-a-haystack" exploration to a confirmed multi-center porphyry copper system in Ontario.
The most recent news (March 16, 2026) reports the final assay results from the 2025 drilling program at the Soo Copper Project. Key highlights include drill hole MEPS-25-20, which intersected 235.5m at 0.42% Cu and 0.042 g/t Au (0.5% CuEq), including a high-grade interval of 32.75m at 1.31% Cu and 0.11 g/t Au. Crucially, the company identified a new "Bornite-Covellite Zone," indicating a strengthening copper system to the northwest. This follows the March 1, 2026, announcement of a new Cu-Mo mineralized porphyry stock discovered 1.5km away from the main MEPS zone, which suggests the mineralization is part of a much larger, regional-scale intrusive complex.
The impact is Material - Positive. While the grades in the broad 235m intercept are moderate (0.42% Cu), the consistency of mineralization is remarkable—the CEO noted that in eight months of drilling, they have yet to drill a "zero copper" hole. - Scale Confirmation: The discovery of a mineralized porphyry stock 1.5km from the initial discovery confirms that MEPS is not an isolated occurrence but part of a "giant" system. - High-Grade Potential: The transition to bornite and covellite (high-copper-tenor minerals) in the northwest suggests the company is moving toward the hotter, more mineralized core of the system. - Operational De-risking: The project benefits from year-round access and proximity to Sault Ste. Marie, significantly lowering the cost-per-meter compared to remote Canadian exploration projects.
Sterling Metals is a Canadian explorer focused on the Soo Copper Project (formerly Copper Road) near Sault Ste. Marie, Ontario. The project is located at the intersection of the Midcontinent Rift and the Kapuskasing Fault Zone. It is characterized as a large-scale Cu-Mo-Au-Ag porphyry system. The company also holds the Adeline (Labrador) and Sail Pond (Newfoundland) projects, though focus has shifted almost entirely to Soo.
