Cuprum Metals Secures $19.4 Million to Scale Copper Extraction Tech

The company’s patented method utilizes a water-based chemical system capable of functioning with seawater, bypassing the need for heat or biological interventions. Unlike traditional mining approaches, the technology functions at room temperature and pressure, reportedly recovering over 75% of copper from chalcopyrite ore within 100 days. This chemical-first methodology, pioneered by founder Roger Pettman, allows for processing across a diverse range of feedstocks, including primary sulfide ores, smelter slags, and legacy tailings.

Investors are betting on the technology's ability to bridge the widening supply gap in the copper market. By reducing both capital and operating costs, the process offers a flexible solution for mining operations in regions ranging from South Africa and Chile to Australia and the United States. With this Series A funding, Cuprum plans to scale its industrial application, expand its technical capabilities, and grow its workforce to meet rising demand for more efficient resource recovery.
