El Espino Iron-Oxide Copper Gold District, Coastal Cordillera of North-Central Chile, The
The El Espino Iron Oxide Copper Gold (IOCG) mining district is located in the Coastal Cordillera of north-central Chile and includes the El Espino deposit which has a measured plus indicated geologic resource of 145 Mt at 0.55 percent Cu and 0.22 g/t Au. Mineralized bodies are distributed in a 7 x 10 km2 area and range in geometry from single veins to stockworks and breccias to manto-type deposits. The ore bodies are hosted primarily by Early Cretaceous volcanic, volcaniclastic, and sedimentary units, with fewer mineralized zones within a Late Cretaceous multi-phase intermediate pluton.
