NexMetals Validates 30.8% Cu, 10.8% Ni Concentrates Meet Smelter Specifications
NEXM•Final assays from NexMetals’ Selkirk Mine test confirm copper concentrates grading 30.8% Cu and nickel concentrates grading 10.8% Ni meet industry-standard smelter specifications with deleterious elements below penalty thresholds. These results support a lower-capital restart pathway without on-site smelting and bolster the project’s marketability and valuation.
1. Metallurgical Test Program Results
NexMetals completed a two-concentrate metallurgical test on 700 kg of diamond drill core composite from the Selkirk Mine, demonstrating a conventional sequential flotation flowsheet can yield separate, high-grade copper and nickel concentrates.
2. Commercial Smelter Specifications
Final analytical assays show copper concentrate at 30.8% Cu and nickel concentrate at 10.8% Ni, with all deleterious elements—arsenic, cadmium, mercury, fluorine, lead, zinc, bismuth—below industry penalty thresholds.
3. Potential Low-Capital Restart Pathway
The clean concentrate profile eliminates the need for an on-site smelter or hydrometallurgical plant, potentially reducing capital intensity and execution risk for a Selkirk Mine restart.
4. Next Steps and Timeline
Further flowsheet development testwork will target improved recoveries and concentrate quality, with metallurgical results to be integrated into a New Mineral Resource Estimate due in Q2 2026.
