The Resolution Copper project is a proposed underground copper mine in the Copper Triangle, approximately 60 miles east of Phoenix, Arizona, in the western United States.

Resolution Copper has the potential to be one of the biggest copper mines in America and create several thousand direct and indirect jobs.

Resolution Copper will rely on a technique called caving to extract the deposit that lies more than 2,000 metres deep. This technique uses gravity to help extract the ore and is the most viable way to recover the resource.

The US Forest Service (USFS) continued work to progress the Final Environmental Impact Statement and complete actions necessary for the land exchange. We continued to advance partnership discussions with several federally recognised Native American Tribes who are part of the formal consultation process.

In September 2024, the Apache Stronghold filed a petition to the U.S. Supreme Court requesting to hear its case to stop the land exchange between Resolution Copper and the federal government. The Court has not yet issued its decision on this petition. While there is significant local support for the project, we respect the views of the groups who oppose it and will continue our efforts to address and mitigate these concerns.
