A classic porphyry copper deposit and the world's largest open pit copper mine. From 1915 until 1997, it produced 31 million tons of copper metal, with an equivalent amount still remaining in the main orebody.
Chuquicamata is now amalgamated with the operating Radomiro Tomić mine to the north (but still on the same mineralised system), the developing Alejandro Hales mine just to the south (formerly Mansa Mina, a slightly impolite description) and the recently discovered 'Toki cluster' of copper porphyries to form the Codelco Norte division of Codelco.
Located 15 km north of Calama, II Region, Chile.
134 valid minerals. 19 (TL) - type locality of valid minerals.
