AMIS0450 PGM 3E 4.95g/t Merensky South Africa
Origin of Material: AMIS0450 was made from material supplied by Anglo Platinum, using Merensky Reef underground sample material from the Western Limb of the Bushveld complex.
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.
