Locality type:Deposit


Gold deposit.

Gold is hosted in a system of massive and sheared, milky, sulphide-bearing quartz veins cutting a sequence of Neoproterozoic metavolcanic/volcaniclastic rocks and related banded iron formation (BIF). Gold-base metal mineralisation is associated with brecciation and fracturing of the iron ore bands, close to silicified shears and related quartz veins.

Note on the mineral list: Zoheir & Akawy (2010) also mention telluride specks in a few samples.
