Chile's III region was the mining centre for copper, gold and silver starting in the 16th century.
With the discovery of large porphyry deposits inland, mining halted on the coastal cordillera.
Mechanized mining methods and exploration techniques have improved in the last century giving the region new potential.
Present day mining in the region includes large iron mines and revived small scale copper, gold and silver mines as well as several large IOCG copper gold mines such as Candelaria and Mantos Verde.
