The remaining reserves of copper ore in Chile were reported by the Central Bank for the period 1985–1997 and by the United States Geological Survey (USGS) from 1998 onwards (USGS 2017). Remaining reserves are those available after discounting yearly refined production. Three scenarios were considered for future copper reserves in Chile.

All the ores are of a complex nature, with almost 45 per cent occurring as oxides and carbonates which are, for the most part, acid soluble. The ore contains chalcocite, chalcopyrite, bornite and covellite as sulphides and cuprite, tenorite, malachite, azurite and chrysosolla as oxides, carbonates and silicates and native copper.
