SCC is one of the largest integrated copper producers in the world. We produce copper, molybdenum, zinc, lead, coal and silver. All of our mining, smelting and refining facilities are located in Peru and Mexico and we conduct exploration activities in those countries and Chile. Since 1996, our common stock is listed on both the New York and Lima Stock Exchanges.Our Peruvian copper operations involve mining, milling and flotation of copper ore to produce copper concentrates and molybdenum concentrates; the smelting of copper concentrates to produce anode copper; and the refining of anode copper to produce copper cathodes. As part of this production process, we also produce significant amounts of molybdenum concentrate and refined silver. In addition we produce refined copper using SX/EW technology. We operate the Toquepala and Cuajone mines high in the Andes Mountains, approximately 860 kilometers southeast of the city of Lima, Peru. We also operate a smelter and refinery west of the Toquepala and Cuajone mines in the coastal city of Ilo, Peru.

SCC Mexican operations are conducted through our subsidiary, Minera Mexico S.A. de C.V. ("Minera Mexico"), which we acquired on April 1, 2005. Minera Mexico engages principally in the mining and processing of copper, molybdenum, zinc, silver, gold and lead. Minera Mexico operates through subsidiaries that are grouped into three separate units. Mexicana de Cobre S.A. de C.V. operates La Caridad, an open-pit copper mine, a copper ore concentrator, a SX/EW plant, a smelter, refinery and a rod plant. Mexicana de Cananea S.A. de C.V. operates Cananea, an open-pit copper mine, which is located at the site of one of the world's largest copper ore deposits, a copper concentrator and two SX/EW plants. Industrial Minera Mexico, S.A. de C.V. and Minerales Metalicos del Norte, S.A. (together with its subsidiaries, the "IMMSA Unit") operate five underground mines that produce zinc, lead, copper, silver and gold, a coal mine and several industrial processing facilities for zinc.We utilize modern/state of the art mining and processing methods, including global positioning systems and computerized mining operations. Our operations have a high level of vertical integration that allows us to manage the entire production process from mining of the ore to the production of refined copper and other products.
