IOCG
OREAS 523b
رمز المنتج: 523b
OREAS 523b was prepared from a blend of iron oxide copper-gold (IOCG) ore,
barren rhyodacite and iron oxide ore. The IOCG ore was sourced from the Ernest
Henry Mine located about 38 kilometres north-east of Cloncurry in north-west
Queensland.
IOCG mineralisation at the Ernest Henry Mine is hosted in 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.
Twenty-nine commercial analytical laboratories participated in the program to
certify the elements reported below. The following methods were employed:
Gold by fire assay (25-50g charge weight) with AAS, ICP-OES or ICP-MS
finish
Gold by aqua regia digestion (15-30g sample weight) with AAS, ICP-OES or
ICP-MS finish
Full ICP-OES and ICP-MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl)
digestion
Full ICP-OES and ICP-MS elemental suites by aqua regia digestion
Full ICP-OES and ICP-MS elemental suites by peroxide fusion
Ag, As, Cu, Co, Fe, Mo and S by 3-acid (HNO3-HClO4-HCl) digestion with
ICP-OES finish
Total Sulphur by infrared combustion furnace and
Fluorine by various methods.
Instrumental neutron activation analysis for Au on 20 x 85mg subsamples was
also undertaken at ANSTO, Lucas Heights to confirm
homogeneity.
