Geoscience Australia has identified new opportunities for critical minerals, copper, gold, and groundwater across a vast under-explored region of south-eastern Australia.

Delivered as the first deep dive study under the Australian Government’s 35-year Resourcing Australia’s Prosperity initiative, the Delamerian project(https://www.ga.gov.au/scientific-topics/resourcing-australias-prosperity/deep-dives/delamerian) offers a detailed analysis of the region and its prospects.

The project's achievements include confirmation of a 1,000-kilometre continental-scale arc system - buried beneath the sedimentary cover of South Australia, New South Wales and Victoria - and refined insights into exploration opportunities for critical minerals, copper and gold.

The work also strengthens understanding of groundwater resources that support communities, industry and the environment, providing a stronger evidence base for water planning and resource management.

Chief of Geoscience Australia's Minerals, Energy and Groundwater Division, Dr Andrew Heap, said the Delamerian project demonstrates the benefits of long-term investment in nationally significant precompetitive geoscience under the Resourcing Australia’s Prosperity initiative.
