Mineralisation:
OREAS 197 has been prepared from a blend of scandium mineralised laterite sourced from the Nyngan (Gilgai and Honeybugle) deposits, located about 450kms northwest of Sydney (Australia), supplemented with ferruginous soil (sourced from soils developed over Tertiary tholeiitic basalt in eastern Melbourne, Australia) and a small quantity of low grade, Ni-Co laterite ore sourced from the Bulong deposit, 35km east of Kalgoorlie in Western Australia.
The Nyngan scandium ore is sourced from the upper lateritic zone consisting haematitic and limonitic clays from humid weathering of mafic/ultramafic rocks.
The Bulong ore formed from prolonged lateritic weathering of Archaean (Yilgarn Craton) olivine rich ultramafic/komatiite flows. Grades of >1% Ni were generated in zones of more intense weathering associated with faulting and bedrock alteration. The Ni-Co nontronitic (Fe-Ni smectite clays) siliceous ores at Bulong formed with a goethitic overprint in the upper laterite profile.
