OREAS 524
OREAS 524 was prepared from a blend of iron oxide copper-gold ore, Cu-Au concentrate and magnetite-bearing waste rock (altered, porphyritic, intermediate volcanic rock). The mineralisation is hosted by a breccia comprising strongly altered and replaced felsic volcanic fragments in a matrix largely composed of magnetite, calcite, pyrite, biotite, chalcopyrite, K feldspar titanite and quartz. Accessory minerals include garnet, barite, molybdenite, fluorite, amphibole, apatite, monazite, arsenopyrite, a LREE fluorcarbonate, galena, cobaltite, sphalerite, scheelite, uraninite and tourmaline. Copper occurs as native copper, bornite and chalcopyrite. Gold occurs mainly in the molecular framework of the chalcopyrite. Significant levels of cobalt, molybdenum, rare earth elements and low levels of uranium are also present. The ore, concentrate and waste materials were sourced from the Ernest Henry Mine located about 38 kilometres north-east of Cloncurry in north-west Queensland.
