OREAS 59d
OREAS 59d 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.
