About Us

The Resolution Copper project is a proposed underground mine 60 miles east of Phoenix, Arizona, near the town of Superior. The project is a joint venture owned by Rio Tinto (55%) and BHP (45%).

The ore deposit lies nearly 7,000 feet below the earth’s surface. It represents one of the most significant untapped copper deposits today, with an estimated copper resource of 1.787 billion metric tonnes at an average grade of 1.5% copper. The mine has the potential to supply nearly 25% of US copper demand.

The mine will create several thousand direct and indirect jobs, with an economic value of several billion dollars over the estimated mine life. Resolution will also serve as an engine for economic growth, and use best practices to create a safe, sustainable, and environmentally friendly operation.

The copper from the mine will be used to produce vital products that modern society depends upon, such as electric vehicles, smartphones, and MRI scanners.

Permitting is well-underway, and the public plays a significant role in planning and approving the project.
