AMIS0338 Li 0.168% Ta 43ppm Pegmatite Mt Cattlin Australia
Origin of Material: AMIS0338 is a commissioned CRM made using ore sourced from the Mt Cattlin Spodumene Mine situated at Ravensthorpe 430km east south east of Perth in Western Australia. The ore was supplied by Galaxy Resources through SGS Mineral Services Ltd. The Mt Cattlin project is located in the Phillips River Mineral Field, within the Ravensthorpe Terrain, which forms part of the Archaean greenstone belt. The pegmatite’s which comprise the orebodies comprise sub-horizontal dykes, hosted by both volcanic and intrusive rocks.
Mineral and Chemical Composition: The pegmatite’s comprise quartz, albite, microcline, perthite, spodumene, muscovite and lepidolite. The predominant lithium mineral is spodumene. There are economically significant grades of tantalum present as columbite, tantalite and microlite
