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.

Summary
Stability of accessory minerals during low temperature geological processes. 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 incl ....Stability of accessory minerals during low temperature geological processes. 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. 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
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
