This study focuses on the LG-6 and LG-6A chromitite seams at the Thaba mine located on the western limb of the Bushveld Complex. Platinum group minerals and base-metal sulfides are studied by mineral liberation analysis and electron microprobe analysis to define distinct assemblages and to evaluate the potential for beneficiation. Two distinct major mineral assemblages are defined: The first assemblage is rich in PGE-sulfides and alloys of Fe and Sn as well as chalcopyrite, pentlandite while second assemblage is rich in PGE-sulfarsenides and -arsenides and -alloys of Sb and Bi, pentlandite and Co-rich pentlandite.
