AbstractIron oxide copper-gold (±Ag±Nb±P±REE±U) deposits form an attractive target for mineral exploration in Canada as they can host significant resources in base, precious, and strategic metals, as well as energy, and are under-explored across the country. This new deposit type includes a large spectrum of sulphide-deficient, mono- to polymetallic breccias, veins, disseminations, and massive lenses with more than 20% low-Ti magnetite and/or hematite. These hydrothermal deposits are associated with large-scale continental A- to I-type granitic suites with intermediate and mafic facies, alkaline-carbonatite stocks, crustal-scale fault zones, regional sodic-calcic alteration, focused potassic and iron oxide alteration, and coincident aeromagnetic and gravity highs. Shallow- to mid-crustal intracratonic, intra-arc or back-arc continental extensional settings, and late- or post-orogenic settings are currently considered prospective for iron oxide copper-gold (IOCG) deposits. Though there is no producing IOCG mine in Canada, three IOCG deposits are known and exploration is accelerating in prospective Proterozoic granitic, gneissic, and sedimentary belts of the Canadian Shield and the Cordillera, as well as Phanerozoic settings in the Appalachian and Cordilleran orogens.
