Iron oxide copper gold (IOCG) deposits are considered to be metasomatic expressions of large crustal-scale alteration events driven by intrusive activity. The deposit type was first recognised by discovery and study of the supergiant Olympic Dam copper-gold-uranium deposit (Olympic Dam mine), and South American examples.

Platinum arsenide, sperrylite (PtAs 2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario ...
