AMIS0530 PGM 4E 3.08g/t UG2 Bushveld South Africa
Origin of Material
This CRM is made from UG2 Run of mine material.
Approximate 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.
