Iron oxide copper gold ore deposits Wikipedia

Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging

Preliminary Model of Porphyry Copper Deposits

Copper skarn deposits occur near many porphyry copper host intru- sions that intruded carbonate-bearing units (Einaudi and others, 1981), and skarn mineral zoning patterns may be useful in the targeting of a potentially associated porphyry copper deposit (Meinert and others, 2005).
