Cuprum Metals Raises $19.4 Million To Scale Copper Extraction Technology

June 21, 2026 - 03:03

Cuprum Metals has closed a $19.4 million Series A funding round to accelerate the commercial rollout of its copper extraction technology. The investment was led by the Lundin Family Office, with additional backing from Woodline Partners and BHP Ventures.

The company said the capital will be used to scale its patented leaching process, which has already shown strong results in pilot tests. Those tests covered both primary and secondary copper sources. The technology aims to improve recovery rates while reducing the environmental footprint compared to traditional smelting methods.

Copper demand is rising sharply due to its use in electric vehicles, power grids, and renewable energy infrastructure. Mining companies are under pressure to find cleaner and more efficient ways to process ore. Cuprum's approach targets lower-grade materials that are often left behind by conventional methods.

The involvement of BHP Ventures, the venture arm of the global mining giant, signals industry interest in alternative extraction technologies. The Lundin Family Office also brings deep experience in base metals investment.

Cuprum did not disclose a valuation for the round. The company plans to use the funds to move from pilot-scale operations to larger demonstration facilities, with an eye toward full commercial deployment in the coming years.
