AMIS0168 Platinum concentrate 4E 208.4g/t, UG2 SA
Origin of Material: This standard was made using UG2 Reef Pt/Pd concentrate material supplied by Anglo Platinum Limited from their Rustenburg Concentrators.
Mineral and Chemical Composition: The UG2 chromitite ore consists of fine to medium size cumulus chromite grains with substantial amounts of post-cumulus orthopyroxene crystals. The footwall is a coarse grained pegmatoidal pyroxenite with sporadic occurrences of chromitite blebs, lenses and stringers. The hanging wall is predominantly fine to medium grained orthopyroxenite with three or more chromitite stringers referred to as the UG2 leaders. The concentrates produced have had most of the chromitite and some of the silicates removed Major element chemistry data from 9 of the labs has been compiled and certified. Uncertified summary statistics for trace element data are set out in the appendix.
