The ore genesis is related to metamorphic/metasomatic transformations of geochemically specialized carbon-bearing sediments.
The platinum/native metals mineralizations preceded the gold ore stage.
The reduced metal forms, including PGE, originated during hydrogen-induced reduction coupled with oxidation of hydrocarbons.
Gold-bearing quartz-pyrite veinlets were deposited from hot brine hydrothermal fluids.
