OREAS 902

SKU: 902

OREAS 902 is a low-grade transitional copper ore certified reference
material. It is one of a suite of four transitional to oxide copper
(±gold) CRMs prepared from samples sourced from CST’s Lady Annie Mine,
located 120 kms northwest of Mount Isa, Queensland, Australia. Mineralisation at
Lady Annie is hosted in dolomitic, carbonaceous and argillaceous sandstones and
siltstones. The primary copper sulphide mineralisation at depth is dominated by
chalcocite and chalcopyrite and appears to be structurally controlled, being
commonly associated with fault-related silicification. Nineteen commercial
analytical laboratories participated in the program. The following methods were
employed:

Full ICP-OES and ICP-MS elemental suites by four acid digestion
Full ICP-OES and ICP-MS elemental suites by aqua regia digestion
Soluble Cu by 5 % H2SO4 acid leach with AAS or
ICP-OES finish
