The Mount Carlton high sulphidation epithermal Au-Ag-(Cu) deposit is located in the northern Bowen Basin, Northeast Queensland, Australia. The deposit is hosted in coherent and proximal clastic facies of a rhyolite unit belonging to the Lizzie Creek Volcanics, a sequence of Early Permian andesitic to rhyolitic calc-alkaline volcanics deposited during the early phases of continental back-arc rifting. The deposit shows alteration zonation characteristic of high sulphidation epithermal deposits, from residual quartz and quartz-alunite-pyrite assemblages zoned outwards to quartz-dickite-pyrite kaolinite (together termed advanced argillic), illite-smectite-pyrite kaolinite chlorite (argillic) and chlorite-smectite-illite-carbonate-zeolite (propylitic) (Figure 1). Sulphide-sulphosalt and pathfinder element distribution defines plume-like geometries interpreted to be controlled by the interplay of active faults and lithologically controlled alteration zones displaying contrasting rheological and permeability characteristics. High grade gold, silver and copper are associated with structurally controlled, multi-phased veins and breccias of pyrite-enargite-sphalerite-galena-barite-alunite (plus other minor sulphosalts, sulphides and tellurides) that cross-cut the advanced argillic altered rhyolite. Lower grade ore is associated with sulphide-sulphosalt disseminations and veinlets marginal to high grade structures. CITATION: Howard, N, 2019.
