The new granite-gold connection. A new granite-gold connection has been recognized by the research team. This exciting breakthrough has challenged traditional concepts concerning the formation of gold deposits. Globally such deposits constitute a major economic resource (>50M.oz.), however, to find more granite-related gold we need to fully understand key issues regarding their genesis and their relationship to other granite and non-granite related deposit types. We propose to study occurrences ....The new granite-gold connection. A new granite-gold connection has been recognized by the research team. This exciting breakthrough has challenged traditional concepts concerning the formation of gold deposits. Globally such deposits constitute a major economic resource (>50M.oz.), however, to find more granite-related gold we need to fully understand key issues regarding their genesis and their relationship to other granite and non-granite related deposit types. We propose to study occurrences in the Hodgkinson Province of North Queensland, and compare this region with other granite-gold terranes in order to assess the critical ingredients in granite-gold formation. Outcomes will enhance our ability to find new gold deposits.Read moreRead less
Understanding the stratigraphic and structural architecture of late Archean basins and the context of their gold deposits. Gold mined from Archean rocks contributed $4.0 billion to Australia's export income in 2006 and provided the backbone of support for many remote communities. However, production has fallen 40% since 1997 and will be exhausted within 15 years unless major new discoveries are made. The potential to find additional gold deposits remains high, but urgently requires new data and ....Understanding the stratigraphic and structural architecture of late Archean basins and the context of their gold deposits. Gold mined from Archean rocks contributed $4.0 billion to Australia's export income in 2006 and provided the backbone of support for many remote communities. However, production has fallen 40% since 1997 and will be exhausted within 15 years unless major new discoveries are made. The potential to find additional gold deposits remains high, but urgently requires new data and improved exploration techniques to assist in their discovery. The results of this integrated multidisciplinary project will help to arrest the declining discovery rate and thereby sustain this important Australian industry.Read moreRead less
A mineral systems analysis of Australia's largest gold producing deposit: Sunrise Dam Gold Mine, Western Australia. This project will augment existing mineral resources at Australia's largest current gold producing mine, and guide exploration for additional resources in the surrounding district.

This project will augment existing mineral resources at Australia's largest current gold producing mine, and guide exploration for additional resources in the surrounding district. By understanding the genesis of this exceptional deposit, the study will spawn a new set of targeting criteria that can be used to explore for other world-class deposits in Western Australia and similar geological terranes throughout the world. In the context of high and rising gold prices, the project has the potential to generate billion dollar revenues and substantial employment, and it will deliver advanced training at undergraduate and postgraduate levels.

Deformational controls on the dynamics of fluid flow, hydrothermal alteration and gold mineralisation, Argo Gold deposit, WA. Detailed structural analysis, combined with major and trace element geochemistry and stable isotope geochemistry, will be used to explore the 3D evolution of fluid pathways and their relationship to growth of shear zones, vein networks and alteration patterns in the Argo shear-hosted gold deposit. The research will be used to (1) maximise the efficiency of resource defini ....Deformational controls on the dynamics of fluid flow, hydrothermal alteration and gold mineralisation, Argo Gold deposit, WA. Detailed structural analysis, combined with major and trace element geochemistry and stable isotope geochemistry, will be used to explore the 3D evolution of fluid pathways and their relationship to growth of shear zones, vein networks and alteration patterns in the Argo shear-hosted gold deposit. The research will be used to (1) maximise the efficiency of resource definition and extraction, (2) refine resource exploration models, (3) explore the dynamics of gold mineralisation processes in shear zones, and (4) advance understanding of how coupling between deformation, fluid flow, and fluid-rock reaction influence the mechanical behaviour of the Earth's crust.Read moreRead less
A Multi-Isotope, Multi-Mineral Approach to Chronology of Deformation, Metamorphism and Gold Mineralisation in the Eastern Goldfields Province, Western Australia. Following recent research, an excellent framework is emerging for the evolution of the Eastern Goldfields Province. However, the weak link remaining is the precise timing of post-depositional geological events. The majority of available ages are equivocal because only single ?non-robust? isotope systems were used. This project will be t ....A Multi-Isotope, Multi-Mineral Approach to Chronology of Deformation, Metamorphism and Gold Mineralisation in the Eastern Goldfields Province, Western Australia. Following recent research, an excellent framework is emerging for the evolution of the Eastern Goldfields Province. However, the weak link remaining is the precise timing of post-depositional geological events. The majority of available ages are equivocal because only single ?non-robust? isotope systems were used. This project will be the first to take a multi-isotope and multi-mineral approach to constrain the temporal framework for the geological history of the Province. It will also provide an unequivocal guide to the robustness of the various isotopic methods and enable a careful reassessment of existing data and identification of appropriate methodology for future research.Read moreRead less
Fluid chemistry and critical mineral enrichment in salty metamorphic belts. Several geological regions in Australia are worth billions of dollars to our economy in their contained copper-goldcobalt and uranium-rare earth element mineral deposits. These regions will continue to be important to Australia as the world transitions to a renewable energy economy because they can provide some of the most critical metals needed for that transition: Cu, Co, rare earth elements. This project aims to provi ....Fluid chemistry and critical mineral enrichment in salty metamorphic belts. Several geological regions in Australia are worth billions of dollars to our economy in their contained copper-goldcobalt and uranium-rare earth element mineral deposits. These regions will continue to be important to Australia as the world transitions to a renewable energy economy because they can provide some of the most critical metals needed for that transition: Cu, Co, rare earth elements. This project aims to provide a fundamental quatitative understanding of the geological processes that form these deposits. We will conduct experiments to generate quantitative models of the metamorphic and structural processes that control the liberation and migration of highly saline fluids, which are ideal for transporting a large range of metals.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

The project will contribute to a better understanding of plate tectonic processes and will provide insights into the dynamics of the Indo-Australian plate. This information is fundamentally important for estimating seismic hazards and the potential for generating large magnitude earthquakes in Australia. Outcomes of this project will facilitate to unravel analogue tectonic systems that were active during the geological evolution of Australia (e.g. the Lachlan fold belt in eastern Australia), thus providing a new insight into the Australian environment. The project will also elucidate the nature of tectonic processes that are known to generate major ore deposits and is therefore likely to have important economic implications.Read moreRead less
