    A comprehensive characterisation of the weathered ore was carried out, where physical, chemical, and mineralogical and liberation properties of the sample were determined. The performance of the weathered ore during flotation was investigated using a pilot plant. It was found that the ore contains 3g/t of 4E PGMs (Pt, Pd, Ru and Au).
