A little history about Copper: The Santa Rita mine in southwest New Mexico was the first copper mine in what is now the western United States. Spaniards began mining copper there about 1800. The district still produces copper, from the large Chino Mine open pit.
Native Americans had mined turquoise associated with the copper deposits at present-day Tyrone in Grant County, New Mexico. Modern mining followed the discovery of turquoise and copper by American prospectors in 1870. The first copper was shipped from the Tyrone district in 1879.
Some copper has been produced from three deposits in sandstone of the Triassic Chinle Formation in the Nacimiento Mountains near Cuba, New Mexico. The copper is present as sulfides (most commonly chalcocite) and malachite associated with organic material; some native silver is also present.
New Mexico is currently the nation’s number-three copper-producing state. Copper is produced from two large open-pit porphyry copper operations in Grant County: the Chino Mine and the Tyrone mine. Both mines are owned and operated by Freeport-McMoRan. In 2007, the two mines produced 249 million pounds (113 thousand tonnes) of copper, as well as 13 thousand ounces of gold and 209 thousand ounces of silver
