Southern Copper Corporation is an integrated copper producer with major production in copper, molybdenum, zinc, and silver. The company's mining, smelting, and refining facilities are located in Peru and Mexico, with exploration activities also conducted in Argentina and Chile. Southern Copper is one of the largest mining companies in Peru and Mexico and holds the largest copper reserves globally. Incorporated in Delaware in 1952, the company has operated copper mines since 1960, and its common stock has been listed on the New York and Lima Stock Exchanges since 1996. In Peru, Southern Copper's operations include mining, milling, and flotation of copper ore to produce copper, smelting copper concentrates into blister and anode copper, and refining anode copper into copper cathodes. This process also yields significant amounts of molybdenum concentrate and sulfuric acid. The Ilo refinery's precious metals plant produces refined silver, gold, and other materials. The company also produces refined copper using solvent extraction/electrowinning (SX-EW) technology. Peruvian operations include the Toquepala and Cuajone open-pit mines, located approximately 860 kilometers southeast of Lima, Peru, and a smelter and refinery in the coastal city of Ilo, Peru. Mexican operations are conducted through the subsidiary Minera Mexico, S.A. de C.V., acquired in 2005. Minera Mexico primarily mines and processes copper, molybdenum, zinc, silver, gold, and lead, operating through subsidiaries grouped into three separate units, including Mexicana de Cobre, S.A. de C.V.
