OREAS 520c
SKU: 520c
OREAS 520c 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.
The Certification Program will include:
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/MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl) digestion
Full ICP-OES/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
Fluorine and chlorine by various methods.
