Where you'll be working

Once in operation, Resolution Copper has the potential to supply nearly 25% of US 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 mine life.

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