Codelco (Corporación Nacional del Cobre de Chile or, in English, the National Copper Corporation of Chile) is a Chilean state owned copper mining company. It was formed in 1976 from foreign-owned copper companies that were nationalised in 1971. The headquarters are in Santiago and the seven-man board of directors is appointed by the President of the Republic.
It has the Minister of Mining as its president and six other members including the Minister of Finance and one representative each from the Copper Workers Federation and the National Association of Copper Supervisors. It is currently the largest copper producing company in the world and produced 1. 66 million tonnes of copper in 2007, 11% of the world total. It owns the world's largest known copper reserves and resources. At the end of 2007 it had a total of reserves and resources of 118 million tonnes of copper in its mining plan, sufficient for more than 70 years of operation at current production rates. It also has additional identified resources of 208 million tonnes of copper, though one cannot say how much of this may prove economic. Codelco's principal product is cathode copper. It is also one of the world's largest molybdenum producers, producing 27,857 fine metric tons in 2007, and is a large producer of rhenium, of which Chile is the world's largest producer.
