Iron oxide copper-gold (IOCG) deposits are major sources of Cu, contain abundant Fe oxides, and may contain Au, Ag, Co, rare earth elements (REEs), U, and other metals as economically important byproducts in some deposits. They form by hydrothermal processes, but the source of the metals and ore fluid(s) is still debated.

Australia is blessed with a wealth of mineral resources, and in terms of copper, the most famous deposit class present throughout the Australian continent would have to be Iron-Oxide-Copper-Gold (IOCG) deposits. I've been lucky to work on a variety of these deposits in one capacity or another. Although the IOCG classification term is a bit of a "bin", it generally refers …
