Announcement summary: | Prominent Hill is an iron oxide copper gold (IOCG) deposit located in the Gawler Craton, South Australia (Figure 1). The Gawler Craton covers approximately 600,000 square kilometres of South Australia. The Gawler Craton hosts Olympic Dam, Prominent Hill, Carrapateena, and a number of other smaller and subeconomic copper-gold deposits. Most of these deposits are thought to be genetically related to the Gawler Range Volcanic (GRV) – Hiltaba magmatic event which affected the central and eastern portions of the Gawler Craton around 1600-1580 million years ago. Copper-gold-silver mineralisation at Prominent Hill is mostly hosted within hematite-matrix breccia. Copper mineralisation occurs as disseminations of chalcocite, bornite and chalcopyrite in the matrix of the breccia. |
