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 …
The discovery of the Olympic Dam, and its definition as a new type of copper deposit with important resources and other commodities (Fe, Au, U) and Iron Oxide-Copper-Gold (IOCG) deposits, has caused great interest in formation processes and characteristic guidelines that are useful for their exploration.

Characteristics of ten of the world's metallogenic provinces hosting iron oxide Cu-Au (IOCG) deposits have been critically assessed, including their geological and tectonothermal evolution, alteration-mineralisation parageneses, and ore geochemistry.
Although they currently supply <5% of the world's Cu and <1% of the world's Au, iron oxide copper-gold (IOCG) deposits are a highly fashionable and poorly understood class of ore deposits. They comprise a wide range of deposits with a primary shared characteristic that is the presence of iron oxide, either magnetite or hematite, in ...
Iron oxide-copper-gold (IOCG) deposits are a globally important source of copper, gold and critical commodities. Despite their relevance, IOCG deposits remain an …
The Salobo deposit is located in the Carajás mineral province, northern Brazil, which is among the world's most endowed mineralized districts (Fig. 1).Salobo was recently classified as an iron oxide copper–gold deposit (Requia and Fontboté 1999, 2000a, 2000b). This deposit occurs in Archean rocks, with reserves estimated at 789 Mt …
Iron oxide copper-gold (IOCG) and iron oxide-apatite (IOA) deposits are major sources of Fe, Cu, and Au. Magnetite is the modally dominant and commodity mineral in IOA deposits, whereas magnetite and hematite are predominant in IOCG deposits, with copper sulfides being the primary commodity minerals.
Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings. The youngest and, therefore, most readily understandable IOCG belt is located in the Coastal Cordillera of northern Chile and …
Many diverse ore systems are classified together as iron oxide copper-gold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of ore-forming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as …
Properties of iron oxide copper gold ore Iron oxide copper gold ore refers to the symbiosis of copper ore and gold ore in gold ore in some form. Its amount is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of 0.2% to 5% and gold with a content of 0.1 to 1.41 grams per ton. Iron oxide copper gold ore tends to be ...

Iron oxide copper-gold (IOCG) deposits are a research focus of the current ore deposit geology, and have attracted much attention among the worldwide geologists and exploration experts due to their shallow depth, a wide variety of mineral species and large scale.
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.
