These deposits occur within a province of proterozoic sediments, which include sedimentary iron formations. Mining was originally for copper, but the high bismuth levels were a serious problem. Gold became a primary target later in the life of the field and the main gold ores were not coincident with the high grade Cu ores.

THE RECOVERY OF METALS FROM THE STORA

Iron Oxide Copper Gold (IOCG) deposits are identified by the occurrence of copper-gold sulphide mineralization with large concentrations of iron oxide minerals, mainly magnetite and hematite, as opposed to iron sulphides. These deposits are generally made up of more than 20% iron oxides [Corriveau, 2005]. Some well-known IOCG deposits
