OREAS 59c

OREAS 59c is one of four Cu-Au-As-Co-Fe-Mo-Ni-S certified reference materials (CRM’s) prepared from iron ore copper gold (IOCG) ore sourced from Cloncurry, Qld, Australia. The IOCG deposit is hosted in Proterozoic rocks of the Mt Isa Inlier and primary mineralisation is intimately associated with felsic to intermediate volcanic breccias. The breccias are rich in magnetite and disseminated sulphide mineralization.
