This project aims to reveal the potential for undiscovered economic deposits of rare earth elements within the Australian continent. Future supply of these elements underpins societies transition to clean energy and embrace of high-tech applications. The project expects to greatly enhance our knowledge of Australia’s endowment of rare earth element resources using an array of traditional and innovative geological research methods. Expected outcomes of this project include a greater understanding of how, where and when rare earth element orebodies form in the Earth's crust. This should provide significant benefits to exploring for––and discovering––new orebodies that are required to secure global critical metal supplies. Read moreRead less
Mobility of metals in hydrothermal solutions: critical experiments and numerical modelling tools to improve exploration success and ore processing. After more than 100 years of intense prospecting, ore deposits with a surface expression or a characteristic geophysical signature have been discovered. As a result, the industry needs innovative and quantitative exploration techniques. Geochemical exploration suffers from a growing gap between ever more powerful geochemical analytical capabilities a ....Mobility of metals in hydrothermal solutions: critical experiments and numerical modelling tools to improve exploration success and ore processing. After more than 100 years of intense prospecting, ore deposits with a surface expression or a characteristic geophysical signature have been discovered. As a result, the industry needs innovative and quantitative exploration techniques. Geochemical exploration suffers from a growing gap between ever more powerful geochemical analytical capabilities and the poor understanding of fundamental processes in hydrothermal systems. By combining new experiments on important geochemical systems (association between the trace elements Te and As with Au) with advances in numerical modelling of H2O-CO2-NaCl fluids, the project aims to bring geochemical exploration in line with geophysical exploration.Read moreRead less
Source to spectrum: Finding deposits beyond the Fe oxide-Cu-Au envelope. Source to spectrum: Finding deposits beyond the Fe oxide-Cu-Au envelope. This project aims to improve exploration models for the spectrum of deposits at Olympic Dam. The giant Olympic Dam iron–oxide–copper–gold (IOCG) deposit in the Gawler Craton, discovered 40 years ago, has contributed billions of dollars to the economy. A fluid flow event in the Olympic Dam created a vast, crustal-scale alteration system with a spectrum ....Source to spectrum: Finding deposits beyond the Fe oxide-Cu-Au envelope. Source to spectrum: Finding deposits beyond the Fe oxide-Cu-Au envelope. This project aims to improve exploration models for the spectrum of deposits at Olympic Dam. The giant Olympic Dam iron–oxide–copper–gold (IOCG) deposit in the Gawler Craton, discovered 40 years ago, has contributed billions of dollars to the economy. A fluid flow event in the Olympic Dam created a vast, crustal-scale alteration system with a spectrum of different mineral deposits, many of which are under-explored. This project aims to constrain the source of metal and fluids in the Gawler Craton deposits, determine crustal fertility for deposit formation and develop metal specific 'prospectivity maps' to improve exploration efficiency.Read moreRead less
Hydrothermal remobilisation of base metals and platinum group elements in magmatic nickel deposits. Magmatic nickel sulphide deposits are highly valuable but extremely challenging exploration targets, thought to lack the distinctive geochemical haloes that allow small targets to be identified from sparse drilling. The project will test the potential of hydrothermal remobilisation of nickel, cobalt and platinum group elements to create broad alteration haloes.
Aiding the Search for Diamonds in South Australia: Source and origin of Mesozoic kimberlite dyke swarms and their mantle samples. Because of significant, yet tantalising, alluvial diamond discoveries in the Adelaide Hills and Flinders Ranges over more than 100 years, South Australia can be viewed to have considerable potential as a diamond producer. Yet this potential is unresolved because little is known about the occurrence and diamond content of the kimberlite source rocks that have carried t ....Aiding the Search for Diamonds in South Australia: Source and origin of Mesozoic kimberlite dyke swarms and their mantle samples. Because of significant, yet tantalising, alluvial diamond discoveries in the Adelaide Hills and Flinders Ranges over more than 100 years, South Australia can be viewed to have considerable potential as a diamond producer. Yet this potential is unresolved because little is known about the occurrence and diamond content of the kimberlite source rocks that have carried the diamonds to the near surface and shed them into the weathering environment. This collaborative research project will use new uncommonly available samples provided by commercial diamond exploration to determine the structure , geochemistry and history of the mantle that underlies the Flinders Ranges and Adelaide Hills at depths between 40 and 250km.Read moreRead less
Constraining conditions and timing of orogeny and reworking in the west Musgrave Province. The remote Musgrave Province is one of Australia's prime areas of mineral exploration interest, with about 30 companies holding more than 120 leases over the region. A major factor determining the economic prospectivity of a terrane is the availability of high quality geoscientific data. This project will produce pre-competitive structural, petrological, isotopic, geochemical and geophysical datasets for t ....Constraining conditions and timing of orogeny and reworking in the west Musgrave Province. The remote Musgrave Province is one of Australia's prime areas of mineral exploration interest, with about 30 companies holding more than 120 leases over the region. A major factor determining the economic prospectivity of a terrane is the availability of high quality geoscientific data. This project will produce pre-competitive structural, petrological, isotopic, geochemical and geophysical datasets for the west Musgrave Province that will rival or surpass that available for other regions of Australian crust. This project directly aligns with the National Research Priority goal, developing deep Earth resources, and will reduce the risk to mineral explorers and facilitate economic development within the Ngaanyatjarra Native Title Lands of Western Australia.Read moreRead less
Development of biosensors and bioindicators for gold exploration and processing in Australia. In times of increasing demand for gold and shrinking rates of discovery in Australia, biosensor and bioindicator techniques deliver significant advantages to the Australian mining industry and allow it to retain its international competiveness.

In times of increasing demand for gold and shrinking rates of discovery in Australia, biosensor and bioindicator techniques deliver significant advantages to the Australian mining industry and allow it to retain its international competiveness. The new understanding of the biogeochemical behaviour of gold in soils and other weathered materials developed in a previous ARC Linkage Project enables the development of biosensor and bioindicator technology that will allow mineral explorers to differentiate mineralised from non-mineralised zones using specific (meta) genomic community responses. The new technology will provide cost-efficient and environmentally sustainable techniques for improving exploration success and optimising ore processing.Read moreRead less
