Core Viewpoint - Nord Precious Metals Mining Inc. is advancing its Re-2Ox metallurgical process to recover critical and precious metals from complex concentrates, addressing a global processing bottleneck due to the closure of deleterious metal-tolerant smelters [1][5][8]. Technical Programme Structure - Phase 1 of the testing program will establish operating parameters through systematic bench testing of the Re-2Ox flowsheet, focusing on alkaline pressure leach testing of concentrate samples [3][4]. - Phase 2 will validate continuous operation at pre-pilot scale by processing a single autoclave batch through downstream circuits, addressing reagent recycling for remote deployments [4]. Market Context - The closure of major smelters has created a processing bottleneck for complex concentrates, which Nord's Re-2Ox technology aims to alleviate by converting penalty-bearing feeds into saleable products [5][8]. Commercial Implications - The bench-scale data will support the company's progression toward Technology Readiness Level 7, positioning the Re-2Ox process for commercial licensing after a pilot demonstration [6][8]. - The ability to process deleterious metal concentrates represents a significant commercial opportunity as global ore grades decline and impurity levels rise [8]. Next Steps - Phase 1 data will enable the production of equipment lists and supplier quotations, refining the capital-cost estimate for a planned one-tonne-per-day Re-2Ox pilot line [8][9]. - The company intends to finance Phase 1 using existing resources and a previously announced C$200,000 MICA grant [8]. Company Overview - Nord Precious Metals operates the only permitted high-grade milling facility in Ontario's Cobalt Camp, focusing on high-grade silver and strategic metals recovery [11]. - The company's flagship Castle property has delineated 7.56 million ounces of silver in inferred resources, with an average grade of 8,582 g/t Ag [11]. - Nord's integrated processing strategy leverages the recovery of multiple metals, including cobalt and nickel, to capitalize on the growing demand for battery materials [12][13].
