The National Geochemical Survey of Australia (NGSA) project was established under Geoscience Australia's Onshore Energy Security Program announced in August 2006 and is part of the program's five year plan.
The primary aim of the NGSA is to provide pre-competitive data and knowledge to support exploration for energy resources in Australia. In particular, it will improve the existing knowledge of the concentrations and distributions of energy-related elements such as uranium (U) and thorium (Th) at the national scale.
The project is underpinned by a series of pilot geochemical surveys carried out by Geoscience Australia and the Cooperative Research Centre for Landscape Environments and Mineral Exploration (CRCLEME) to test robust and cost-effective protocols for sample collection, preparation and analysis. Examples of these are the Riverina and the Thomson pilot geochemical surveys.
The current national geochemical survey is being conducted in collaboration with the State and the Northern Territory Geological Surveys.
