Summary:

The Prominent Hill iron oxide copper gold (IOCG) deposit is located in the northeastern portion of the Archaean to Mesoproterozoic Gawler Craton, South Australia. Copper-gold-silver mineralisation at Prominent Hill is mostly hosted within hematitematrix breccia containing fragments of sandstone, siltstone, dolostone, and mafic to intermediate volcanic rocks. Copper mineralisation occurs as disseminations of chalcocite, bornite and chalcopyrite in the matrix of the breccia. The Prominent Hill Open Pit Mineral Resource was fully depleted, with the Open Pit mining operations completed in March 2018. Since 2 quarter 2018, previously stockpiled ore is processed. The ROM stockpiles have been classified as Measured because they have been mined from zones which have been drilled to grade-control spacing. Mining production and reclaim records in conjunction with ROM surveys have supported the construction of open pit ROM stockpile block models at a monthly level of definition.
