Abstract
Ore samples from the footwall type, Cu-Ni-PGE Morrison deposit were analysed. MD3 domain contains mainly chalcopyrite, pentlandite cubanite, mackinawite, pyrrhotite. In MD5 domain chalcopyrite, pentlandite and millerite dominate. The majority of the platinum is present in moncheite which often forms composite grains with hessite. Michenerite is the dominant Pd-phase. Gold is found near large moncheite-hessite grains, in Ni-sulphides and in the secondary magnetite. The platinum to palladium ratio increases almost linearly with depth, which can be a result of collecting palladium by base metal sulphides (mainly pentlandite) which makes Pd concentration in residual sulphide melt less efficient in comparison to Pt. Alternatively, it could be a result of later alteration of the orebody as Pd is more likely to be mobilized by hydrothermal fluids than Pt.
