Kerr Mines acquired the Copperstone gold mine located in Arizona in 2014. The mine is fully permitted with significant mining infrastructure, mineral resources and processing infrastructure in place.
The high-grade Copperstone Mine is located in western Arizona, in the United States, within the Walker Lane mineral belt where it intersects gold provinces in Southern California and Western Arizona. These provinces host a total known gold endowment of over 40 million ounces of gold. Copperstone is located within a lesser-known, globally significant, high-grade gold province.
