Where you’ll be working

Once in operation, Resolution Copper has the potential to supply nearly 25% of U.S. copper demand and create several thousand direct and indirect jobs in the Pioneer Mining District of Arizona, with an economic value estimated at several billion dollars over the life of the mine.

The project will rely on a block caving technique to extract the deposit, which lies more than 2,000 metres below the surface. This method uses gravity to remove the ore and is the most viable way to recover the resource.

In 2019, the project achieved a significant milestone with the issuance of the Draft Environmental Impact Statement (DEIS) by the U.S. Forest Service. In anticipation of the Final Environmental Impact Statement, Resolution Copper continues permitting and community engagement activities, reclamation of the historic Magma Mine site, shaft and underground development studies, and advancing data collection to further orebody knowledge.
