| Trace mineral: | Platinum, Palladium |
| Operation type: | Unknown |
| Deposit type: | Stratiform |
| Production size: | Production occurred |
| Development status: | Producer |
| ore: | Chalcopyrite, Pentlandite, Pyrite, Pyrrhotite |
| gangue: | Gold, Magnetite, Olivine, Pyroxene, Sericite, Serpentine, Spinel, Talc, Zoisite |
| alteration: | Most Intense In Clinopyroxene-Rich Rocks. Alteration Is Deuteric, But Also A Result Of Fluids Mobilized During Eastern Gabbro And/Or Granitic Intrusion. Finally Metamorphosed To Amphibolite-Greenschist Facies. |
| conc_proc: | Pgm Dissolved In Sulfide Liquid; Upon Cooling, They Precipitated Out As Monosulfide Solid Solution (Mms). Further Cooling Causes Sulfide Assemblage To Exsolve From Mms. |
