The Bakers Hill/West River project covers the southern half of the western flank of the Ravensthorpe Greenstone Belt.
The lithological sequence within the project comprises Archaean granitoid gneiss and mafic/ultramafic rocks of the Cocanarup Terrane in the west. Calc-alkaline volcanic rocks of the Annabelle Volcanics underlie the central and eastern portions, with the Manyutup Tonalite in the far east.
Late stage tourmaline-rich pegmatite dyke swarms intrude mainly the Annabelle Volcanics, but also extend into the Cocanarup Terrane, and have been mapped over a strike length of 10km. Pegmatites within the tenements host lithium in minerals such as lepidolite, zinnwaldite and amblygonite, and the pegmatites also contain tantalum and niobium oxides.
Several historic copper-gold prospects also occur on the project. |
