OREAS 199

OREAS 199 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 a small quantity of high grade, Ni-Co laterite ore (sourced from the Bulong deposit located 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 that intruded Cambrian-Ordovician metasediments.

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.
