The Ernest Henry Mining (EHM) orebody. The EHM orebody is an iron oxide copper gold (IOCG) deposit with magnetite being the form of iron ore. EHM's Ore Reserve Estimate at 30 June 2010 is 88 million tonnes at a grade of 1% copper, grams per tonne gold and 23% magnetite.
Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore.
