Two major packages of geoscientific data for the prospective Gawler Craton and Marree regions have been released by the South Australian state government, representing significant potential for expanded exploration.
The Gawler Craton Gravity Survey – located primarily in the Woomera Prohibited Area – and the Marree Magnetic and Radiometric Survey both add critical new precompetitive exploration information to key areas of South Australia, together covering more than 85,000 kilometres of the state’s Far North.
Resources and energy minister Tom Koutsantonis said the data extends support to exploration activities in South Australia.
“Both of these new surveys were funded through PACE 2020, South Australia’s plan for accelerating exploration,” he said.
“The Gawler Craton survey involved the impressive capture of more than 34,000 gravity measurements, providing high-resolution data covering about 42,500 square kilometres.
“The experts within the State Geological Survey assure me the detailed data better defines the covered geology and structures, and is also available in sufficient resolution to identify potential large-scale iron ore, copper and gold targets.”
Conducted in collaboration with the state government, Geoscience Australia and the federal Department of Defence, the tools aim to help explorers reach an estimated $35 billion of potential developments in the region.
