Still Bright uses a hydrometallurgical RACER process to extract copper from sulfide ore at ambient temperature, employing a vanadium-based leach that dissolves copper. The copper-rich solution is regenerated with electricity to reuse the vanadium medium, enabling electrometallurgy and allowing up to about 99% copper recovery with renewable-powered operations. The system is modular and cheaper to scale (70–90% lower capital cost) and can process high-grade ore, tailings, and other difficult materials at mines of various sizes. The company aims to scale from a 2 t/year pilot to a 500 t/year demonstration by 2028 and ultimately deploy 10,000 t/year commercial units to establish a domestic copper supply chain.
