Cuprum Metals develops a patented, water-based chemical leaching technology that operates at room temperature and pressure and can be tuned as a chemical "tool kit" for a variety of ores and tailings. The process is reported to achieve recoveries typically exceeding 75% from predominantly chalcopyrite ore within 100 days and is effective on oxide ores while consuming less acid than standard oxide leach processes. Cuprum's approach can operate using seawater and does not require heating or biological processes, enabling recovery from primary sulfide ores, secondary sulfide tailings, smelter slags and previously processed materials. Test work has been conducted on mines in South Africa, the US, Chile and Australia with strong results. The company was founded in 2024 and is Delaware-based with a Winter Park, Fla. press office; it plans to use Series A proceeds to scale commercial deployment, expand technical capabilities, hire key personnel and grow its customer base. The firm positions its technology as a flexible solution to improve recovery pathways and reduce operating and capital costs for copper assets.
