Mineralisation:
OREAS 45f was prepared from a blend of mineralised lateritic soil, barren lateritic soil and minor additions of gold and nickel ores. The lateritic soil was developed over a Ni-Cu-PGE mineralised contact between gabbro and pyroxenite in a layered mafic intrusive from the Southern Murchison region of Western Australia. It contains anomalous precious and base metal values (Au, PGE’s, Cu and Ni). The barren soil was taken from a layer of mature lateritic soil developed in situ over early Tertiary tholeiitic basalt in outer eastern Melbourne, Victoria, Australia.
