to bring the mine into production. Production at the mine began in the early 1960s, and was intended to replace production of the company's Potrerillos mine, which would be closing. Production from the El Salvador would increase Chile's total output of copper about 450,000 tons of copper per year, rather than a decrease in production, out of satisfaction and relief, the company renamed the mine El Salvador, Spanish The Savior. In 2005 Codelco had planned to shut down the El Salvador mine in 2011 because of declining ore grades and increased costs, but extended the project life by an additional 15–20 years. They' also have a new project call San Antonio that would be located in the old mine at Potrerillos.

Andina Situated some 80 km northeast of the capital, Santiago, the Andina mine was discovered in 1920 but production did not start until 1970. It consists of the Rio Blanco underground (block cave) mine and the Sur Sur open pit and an underground concentrator. Unlike other Codelco mines, it does not have its own smelter. Geologically it consists of about half the Los Bronces-Rio Blanco complex of mineralised breccias, the other half being owned and mined by the Los Bronces mine of Compania Minera Disputada de la Condes which is in turn owned by Anglo American. Originally owned by the American Cerro De Pasco Corporation, who brought the mine to production, it has been gradually built up by Codelco and is now the subject of a major expansion scheme. At the end of 2007, reserves and resources in the mining plan totalled 5,698 million tonnes grading 0.78% copper containing 44.3 million tonnes of metal and additional identified resources of 11,342 tonnes grading 0.52% copper containing 59.6 million tonnes of metal. The orebodies are at considerable heights, between 3,000 and 4,200 metres and operations can be severely affected by the weather. Originally the mine was only the underground block cave and an underground concentrator with an "hotel" (bunkhouse) where the workers live when the Rio Blanco valley is impassable in the winter. Now the Sur Sur and Don Luis breccias above and to the south of the underground mine are being worked as open pits. Production in 2007 was 218,322 tonnes
