South Australia’s Olympic Cu-Au Province hosts some of the world’s great iron oxide copper gold (IOCG) deposits, such as Olympic Dam, Prominent Hill and Carrapateena. The same causative thermal event resulted in variants of this deposit class being created throughout the Olympic Province, which include deposits of skarn-dominated mineralisation formed where hydrothermal fluids interacted with calcareous lithologies. As part of a broader study aiming to characterise proximal to distal footprints of IOCG-type deposits in the eastern Gawler Craton, the South Australian Geological Survey (GSSA), in collaboration with Monax Mining Limited, used the Punt Hill region as a case study for developing a multi-disciplinary approach to characterise, map and predict alteration associated with skarn-dominated mineralisation which was emplaced during the same thermal event that formed IOCG deposits in the eastern Gawler Craton. The GSSA used samples from company and historic drillholes to systematically acquire co-located geochemical, spectral and petrophysical data in the Punt Hill and Red Lake areas. These data were collected from a regional and prospect-scale distribution of drillholes. Spectral scans of drill core, in the visible to thermal infrared wavelength range, were made using the HyLogger-3TM hyperspectral core scanner. Selected sample intervals were analysed for 65 elements by ICP methods, and for fluorine by specific ion electrode. Drillhole core sampling was supplemented by measurements of magnetic susceptibility and specific gravity. Inversion models of regional aeromagnetic and gravity data were generated to improve the understanding of the 3-dimensional distribution of magnetic susceptibility and density in the region. A 3D model of the Punt Hill region was constructed to view, integrate and interpret all datasets generated in this project. A deposit-scale model (covering 1 square km) around the Groundhog prospect was also constructed and is incorporated in the Punt Hill 3D data package. Complete description of results and interpretations are available in Fabris et al. (2018), however, the 3D Gocad model is the ideal platform to view results of this project. This model serves as a 3D mineral potential map that displays components of mineral systems developed in the Punt Hill region down to ~5 km depth.
