Geology of Gold Mineralization & How Gold Deposits are Formed

Deposits of this type are mined for the predominant metals, but the gold is also recovered as a byproduct during processing of the ore. Most byproduct gold has come from porphyry deposits, which are so large that even though they contain only a small amount of gold per ton of ore, so much rock is mined that a substantial amount of gold is recovered. The largest single source of byproduct gold ...

VMS Deposits | Foran Mining Corporation

VMS deposits often have a strong metal zonation, this is seen as the segregation of various metal-bearing sulphides throughout a deposit. In general, copper sulphide (chalcopyrite) forms in the central (or higher temperature) parts of the deposit, such as the stockwork and vent-proximal sulphide lenses. Gold concentrations can often be highest in these copper-rich zones. In contrast, zinc and ...
