Profile

Southern Copper Corporation engages in mining, exploring, smelting, and refining copper ores in Peru, Mexico, and Chile.

It involves in the production of copper and molybdenum concentrates; smelting of copper concentrates to produce anode copper; and refining of anode copper to produce copper cathodes, as well as refined silver and copper.

The company operates the Toquepala and Cuajone mines in the Andes Mountains located southeast of the city of Lima, Peru, as well as a smelter and refinery in the coastal city of Ilo, Peru.

It also operates five underground mines that produce zinc, lead, copper, silver, and gold; a coal mine, which produces coal and coke; and a zinc refinery.

The company was founded in 1952 and is based in Phoenix, Arizona. Southern Copper Corporation is a subsidiary of Americas Mining Corporation.

Properties

Cuajone property

The Cuajone operations consist of an open pit copper mine and a concentrator located in Southern Peru, 30 kilometres from the city of Moquegua and 840 kilometres from Lima.

The concentrator has a milling capacity of 87,000 tons per day. Overburden removal commenced in 1970 and ore production commenced in 1976. The Cuajone operations utilize a conventional open-pit mining method to collect copper ore for further processing at the concentrator.

The Cuajone porphyry copper deposit is located on the western slopes of Cordillera Occidental, in the southern-most Andes Mountains of Peru. The deposit is part of a mineral district that contains two additional known deposits, Toquepala and Quellaveco. The copper mineralization at Cuajone is typical of porphyry copper deposits.

The Cuajone deposit is also located approximately 28 kilometers from the Toquepala deposit and is part of the Toquepala Group dated 60 to 100 million years.

Santa Barbara mining

The Santa Barbara mining complex is located approximately 26 kilometers southwest of the city of Hidalgo del Parral in southern Chihuahua, Mexico.

Santa Barbara includes three main underground mines and a flotation plant and produces lead, copper and zinc concentrates, with significant amounts of silver. Gold bearing veins were discovered in the Santa Barbara district as early as 1536. Mining activities in the 20th century began in 1913.

The mining operations at Santa Barbara are more diverse and complex than any of the other mines in our Mexican operations, with veins that aggregate approximately 21 kilometers in length.

Due to the variable characteristics of the ore bodies, four types of mining methods are used: shrinkage stopping, long-hole drilled open stopping, cut-and-fill stopping and horizontal bench stopping.

The ore, once crushed, is processed in the flotation plant to produce concentrates. The flotation plant has a capacity of 5,700 tons of ore per day. The lead concentrate produced is treated at a third party refinery in Mexico. The copper concentrates were treated at company's San Luis Potosi copper smelter, and the zinc concentrates are either treated at the San Luis Potosi zinc refinery or exported. The copper concentrates are now treated at our La Caridad smelter.

The Santa Barbara district has mineralization to indicate that it will continue to be a significant producer of lead, copper and zinc for decades. The full potential of the district has not yet been defined, but the area seems to justify an increase in exploration.
