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.
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.
Geobiological gold cycling: Golden opportunities for the minerals industry. 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 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
The geomicrobiology and (bio)geochemistry of platinum, palladium and rhodium. Few economic (Platinum) Pt, (Palladium) Pd or (Rhodium) Rh deposits are known in Australia despite an abundance of potential host rock. By improving onshore exploration techniques this project will ensure the supply of these strategic metals to the Australian economy.

By improving onshore exploration techniques this project will ensure the supply of these strategic metals to the Australian economy. By integrating geochemical, molecular microbial and microanalyses (e.g., synchrotron) techniques this project will also: (i) enhance Australia's status in the breakthrough science of Geomicrobiology; (ii) secure a leading role for Australian science in the assessment of anthropogenic Pt, Pd and Rh pollution; (iii) access expertise developed overseas by fostering international collaborations; and (iv) explore the transformational capabilities of microbiota for ore-processing of and nano-particle production.Read moreRead less
Magmatism, Metamorphism and Mineralisation: The Development of an Isotopic and Geochemical Framework for the Curnamona Cu-Au Province. Recent advances have highlighted the potential significance of the Olary Domain in the Curnamona Province in southern Australia as an important Proterozoic copper-gold district. However, an outstanding problem yet to be solved is the interplay between mineralisation, granitic magmatism and the metamorphic history of the Province. This multi-disciplinary project ....Magmatism, Metamorphism and Mineralisation: The Development of an Isotopic and Geochemical Framework for the Curnamona Cu-Au Province. Recent advances have highlighted the potential significance of the Olary Domain in the Curnamona Province in southern Australia as an important Proterozoic copper-gold district. However, an outstanding problem yet to be solved is the interplay between mineralisation, granitic magmatism and the metamorphic history of the Province. This multi-disciplinary project will use isotopic and geochemical tools to develop an integrated geologic framework within which to view mineralisation. The outcomes will enhance the prospectivity of the region and make an important contribution to the globally relevant question of controls on Proterozoic copper-gold systems.Read moreRead less
Physical and Chemical Constraints of Fluid Activated Processes During the Polyphase Tectonic Evolution of the Olary Domain, S.A. The Olary Domain, eastern South Australia, underwent several phases of deformation and metamorphism. These events mobilised fluids leading, amongst other features, to the formation of breccia bodies and mineral deposits. The complex nature of the geological evolution of the region obscures relationships of fluid migration to the structural history. Fluid inclusion stud ....Physical and Chemical Constraints of Fluid Activated Processes During the Polyphase Tectonic Evolution of the Olary Domain, S.A. The Olary Domain, eastern South Australia, underwent several phases of deformation and metamorphism. These events mobilised fluids leading, amongst other features, to the formation of breccia bodies and mineral deposits. The complex nature of the geological evolution of the region obscures relationships of fluid migration to the structural history. Fluid inclusion studies and stable isotope analyses combined with structural analyses on micro to macro scales shall establish links between the thermal and structural evolution of the area. This will provide insigth into the scale and physico-chemical characteristics of fluids and mineralising processes an relate these to the tectono-thermal history.Read moreRead less

Transport of metals in vapours and brines: new insights into the formation of the Earth's mineral deposits. Traditional models for the formation of hydrothermal ore deposits assume that aqueous fluids transported the metals.

Traditional models for the formation of hydrothermal ore deposits assume that aqueous fluids transported the metals. This view is challenged by new observations showing that gold and copper are preferentially enriched in vapours coexisting with salty aqueous fluids in some deposits. This project uses state-of-the-art techniques and develops new instruments to measure experimentally the partitioning of metals between solid, fluid and vapour at temperatures typical for natural ore deposits (350-550C, pressures varying for vapour saturated to 1 kb). By improving our understanding of metal transport within the Earth's crust, these data will lead to improved models and technologies for exploring and processing base and precious metals.Read moreRead less
