Prominent Hill mine, South Australia, Australia
Photo: geomartin
An open-pit mine which commenced production in February 2009.
Owned by OZ Minerals Ltd.
Copper and gold-bearing hematite-rich breccias formed by repetitive hydrothermal brecciation, milling, and explosive venting within a volcanic setting. Iron oxide-sericite-silica alteration is pervasive within and marginal to the main breccias.
Mineralisation is similar to that of the Carrapateena deposit.
In contrast to the Olympic Dam deposit, an iron oxide copper gold deposit of similar age about 200 km to the southeast of Prominent Hill, uranium values do not exceed 150 ppm and therefore uranium recovery is not economical.
Located midway between the Olympica Dam deposit and Cooper Pedy.
