    Iron oxide copper-gold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and or hematite, (4) Fe oxides with Fe Ti greater than those in most igneous rocks, and (5) no clear.Oct 13, 2021 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.The deposit consists of iron oxide containing uranium (0.023 ), copper (1.8 ), gold (0.5 g t), silver (3.6 g t) and rare earth materials (REE). Principal copper-bearing minerals are chalcopyrite, bornite and chalcocite. There also is a small amount of.Iron oxide minerals (limonite), cerargyrite, and jarosite, tend to be relatively insoluble and indicative of deposition from relatively high-pH water.
