Stratabound deposit, hosted in carbonaceous shales.
One of the world's largest gold deposits. Also a PGE deposit.
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.
79 valid minerals.

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
