The Ray Operations consists of an open pit mine with a concentrator and a solvent extraction-electrowinning operation, and associated maintenance, warehouse and administrative facilities. Cathode copper produced in the SX-EW operation is shipped to outside customers and to the Amarillo Copper Refinery.
Ray is located in Pinal County, just 18 miles to the west of the Hayden Operations. The Hayden Operations and General Administrative Offices are located 70 miles northeast of Tucson and 64 miles southeast of Phoenix (Pinal and Gila Counties).
A local railroad, Copper Basin Railway, transports ore to the Ray concentrator to the smelter, and sulfuric acid to the leaching facilities.
