NorthWest Reports Significant Ore Sorting Results at Kwanika

Core Insights - NorthWest Copper Corp. announced positive results from sorting tests at its Kwanika project, indicating potential improvements in mill feed grades and project economics [1][2] Sorting Test Program - The sorting tests utilized X-Ray Transmission (XRT) technology, with a representative sample of approximately 312 kg of mineralized and waste material [4] - The tests were conducted by Canenco Consulting Corp. and Saskatchewan Research Council, focusing on the rejection of barren material to enhance the quality of the mill feed [5][6] Test Work Highlights - The sorting process resulted in a significant increase in sorted metal grades, with copper grades improving by approximately 20%, gold by 18%, and silver by 19% [3][11] - High recovery rates were achieved, with approximately 90% for copper, 88% for gold, and 90% for silver, while only processing 75% of the original mass [12][11] - Low-grade rejects constituted 25% of the overall feed, with a grade of 0.33% Cu, 0.75 g/t Au, and 1.13 g/t Ag, which will be stockpiled for future processing [12] Environmental and Economic Benefits - Incorporating sorting technology is expected to reduce the overall environmental footprint of the project by decreasing greenhouse gas emissions, water usage, and the volume of tailings [13][10] - The potential reduction in mill size and upfront capital costs while maintaining similar production rates for copper and gold enhances the project's economic viability [2][9]
