Description:

OREAS 164 is a medium grade copper ore certified reference material (CRM) prepared and certified by Ore Research & Exploration Pth Ltd. The material was sourced from Xstrata's Mt Isa copper ore deposits located near the township of Mt Isa in north-west Queensland. The ore deposits are hosted by brecciated siliceous and dolomitic rock masses within the Urquhart Shale comprising complex and dissociated veins with chalcopyrite, pyrite and pyrrhotite with grades of 3-4% copper. OREAS 164 is one of a suite of seven CRMs characterised for Cu, Fe, S, CaO, MgO, Al2O3, SiO2, Ag, Pb, Zn and Co by both sodium peroxide fusion ICP and 4-acid ICP methods.
