Measuring mantle hydrogen to map ore fluids and model plate tectonics. The goal of this project is to use magnetotellurics to measure mantle hydrogen content to aid in the discovery of new mineral deposits. Hydrogen controls the strength of Earth’s mantle and is a vital component of the systems that form giant ore deposits. However, mantle hydrogen content is unconstrained. Ore-forming fluids hydrate the mantle pathways on which they travel. The first aim of this project is to image these fluid ....Measuring mantle hydrogen to map ore fluids and model plate tectonics. The goal of this project is to use magnetotellurics to measure mantle hydrogen content to aid in the discovery of new mineral deposits. Hydrogen controls the strength of Earth’s mantle and is a vital component of the systems that form giant ore deposits. However, mantle hydrogen content is unconstrained. Ore-forming fluids hydrate the mantle pathways on which they travel. The first aim of this project is to image these fluid pathways to improve mineral exploration techniques. Plate tectonic models assume that the lithospheric mantle is dehydrated but existing data from magnetotellurics and mantle rocks show high hydrogen contents. The second aim of this project is to create a map of the hydrogen content of the plates, which may lead to new models for continental evolution and mantle dynamics.Read moreRead less

The project aims to improve Australia’s ability to discover mineral deposits beneath sedimentary basins by determining whether detrital accessory minerals in sedimentary basins can be an effective exploration tool. This project expects to generate new knowledge on the stability of detrital accessory minerals in the sedimentary cycle using observations from natural rocks and laboratory experiments. Expected outcomes include an assessment of the accessory minerals that are best suited to exploration vectoring studies in sedimentary basins. This should provide significant benefits to government and industry by improving mineral exploration methods and also has implications for geochronology and provenance studies.Read moreRead less

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
Deep and smelly: exploring the roles of pressure and sulphur in hydrothermal metal transport. Hot, salty fluids carry metals in the Earth's crust and are responsible for the formation of Australia's mineral wealth. This project combines exciting new experiments with molecular-level simulations to predict metal transport, providing a sound basis for improving mineral exploration models and sustaining discovery of new deposits.
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.
Mapping mineral systems of deep Australia. We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration su ....Mapping mineral systems of deep Australia. We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration success. This project will turn Australia’s investment in National geophysical surveys into new discoveries of base metals. The benefit stems from enabling the transition to a clean economy which requires a much broader range of critical minerals and a larger quantity of base metals.Read moreRead less

Linking Australia’s basement and cover mineral systems . The aim of this research is to use revolutionary new mineral-dating techniques to test the hypothesis that low-temperature fluids can transport metals from Australia's richly endowed geological basement to form new mineral deposits in the sedimentary basins that cover most of the continent. Sedimentary-hosted mineral systems are the largest source of the critical metal cobalt and the second largest source of copper on Earth.

The aim of this research is to use revolutionary new mineral-dating techniques to test the hypothesis that low-temperature fluids can transport metals from Australia's richly endowed geological basement to form new mineral deposits in the sedimentary basins that cover most of the continent. Sedimentary-hosted mineral systems are the largest source of the critical metal cobalt and the second largest source of copper on Earth. These two metals are essential to developing the green energy infrastructure and technologies that underpin a net zero economy. The expected outcomes are a detailed record of paleo-fluid flow and metal cycling in Australia's highly prospective sedimentary basins. Read moreRead less

This project aims to develop new geobiological tools for gold exploration and processing that are rooted in a fundamental understanding of geobiological gold cycling. Given the high production costs, the sustainability of the Australian gold industry relies strongly on innovation. Yet, there are many gaps in our fundamental understanding of bio (geo)chemical gold dispersion and precipitation. This project aims to fill these gaps by linking biochemical pathways of gold mobilisation and resistance in bacteria to its transport and biomineralisation. This would enable the development of protein-based biosensors, bioindicators and nanovectors. These would support the development of exploration and bioaccumulation technologies that allow more economically sustainable and environmentally viable mining practices, such as enhancing production from subeconomic ore.Read moreRead less
