This regional gravity survey was proposed by the Geological Survey of South Australia (GSSA) to deliver a vital new precompetitive dataset for explorers targeting Olympic Dam style Iron Oxide Copper Gold (IOCG) mineralisation within the Gawler Graton. The survey has seen 34,541 new gravity measurements added to the state Gravity database at 1km x 1km resolution, except within the continual use zone of the Woomera Prohibited Area (WPA) where resolution is 2km x 2km. Thousands of existing stations were included in the final dataset with many of these previously surveyed by Daishsat. The gravity survey provides new, pre-competitive data that more clearly defines broad geology and structure in deeply covered areas within the Gawler Craton, and is of sufficient resolution to detect large-scale IOCG systems. The survey was successfully completed in September safely, on time and on budget, despite heavy rains and complicated access conditions by our heliborne and ground survey teams.
