OREAS 198

OREAS 198 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).

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.
