UNITED STATES OF AMERICA —Mining venture Resolution Copper has committed 144 million US dollars to fund the next phase of engineering development at its deep underground copper project near Superior, Arizona. Following the execution of a land exchange agreement, the capital commitment will finance comprehensive feasibility studies, detailed engineering for shaft material-handling systems, and the design of new water treatment infrastructure.
Resolution Copper is a joint venture owned by global mining corporations Rio Tinto and BHP, established to evaluate and develop one of North America's largest unexploited copper ore deposits. The United States Department of Agriculture's Forest Service manages federal land allocations and environmental reviews associated with major resource extraction projects across public lands.
The allocation will also support ongoing subsurface exploration drilling, the acquisition of specialized underground extraction machinery, and the procurement of critical electrical infrastructure, including switchgear, circuit breakers, and power transformers. To support expanded site operations, the project entity plans to recruit 50 technical specialists across engineering, geological assessment, and project management disciplines. Located between 5,000 and 7,000 feet underground, the deposit is projected to generate substantial domestic copper supply upon commercial operation.
This capital deployment highlights growing corporate investment in domestic critical mineral supply chains within North America. For electronics manufacturers, clean energy developers, and industrial equipment suppliers, advancing domestic copper production mitigates foreign supply chain exposure, supports long-term material procurement for electrification projects, and drives regional economic activity in Arizona.
