AMIS0209 PGM 4E 2.02g/t Merensky South Africa
Origin of Material: AMIS0209 was made using Merensky Reef Pt/Pd ore material supplied by Anglo Platinum Limited from the Western limb of the Bushveld Complex. This specific material is a blend of ore collected from the Turfontein Mine ore silo and footwall material collected from the Boschfontein Shaft that has been further blended down with blank silica.
Mineral and Chemical Composition: The Merensky Reef comprises components of feldspathic pyroxenite, pyroxenite and anorthosite. Peak PGE values are associated with a thin chromitite stringer. Mineralization in this Merensky Reef comprises 2-5% disseminated or net textured magmatic sulphides, predominantly pyrrhotite, pentlandite, chalcopyrite and pyrite. The PGE’s occur as micron-sized satellite grains around but rarely within the sulphides.
