From exploration to mining: new geological strategies for sustaining high levels of copper production from the Mount Isa district. Mineral production at the Mount Isa copper and Ernest Henry copper-gold mines is worth more than $ 1 billion per year and this has underpinned the northern Queensland economy for a number of years. These resources are being depleted at a high rate, and no significant new discoveries have been made in over a decade. This project will provide some of the tools to defin ....From exploration to mining: new geological strategies for sustaining high levels of copper production from the Mount Isa district. Mineral production at the Mount Isa copper and Ernest Henry copper-gold mines is worth more than $ 1 billion per year and this has underpinned the northern Queensland economy for a number of years. These resources are being depleted at a high rate, and no significant new discoveries have been made in over a decade. This project will provide some of the tools to define new resources for the next generation, ensuring the prosperity of the region and bolstering the Australian economy. The timing is critical given the long lead time between discovery and production (in the order of 5 to 10 years). If successful the research may have major financial impacts at local, regional and national scales. It may also improve mine safety.Read moreRead less
Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may ....Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may delineate adjacent plus regionally distributed zones where the deformation event responsible for mineralization is locally present at sufficient intensity to form ore. This would allow targeted deep drilling in ground with no ore close to the surface saving millions in drilling costs and dramatically increasing the financial viability of this industry.

Computer simulation to study emergence of material texture in the Earth and Plate Tectonics. Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to stu ....Computer simulation to study emergence of material texture in the Earth and Plate Tectonics. Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to study how the upper mantle emerges as a thermo-mechanically distinct boundary layer, how this emergent structure relates to anisotropy in the upper mantle, and how it is affected by cross-scale effects controlling fault zone behaviour and crustal dynamics.Read moreRead less
Modeling fluid flow and mineralisation at crustal interfaces. Several types of mineral resources, including some uranium, iron, and base metal ore deposits, may be created by fluid flow through and around interfaces in the Earth's crust. By understanding how, where and why such deposits form, we will assist exploration for future resources of these metals. Insights will also be gained into petroleum resource generation and extraction, the distribution of seismicity and volcanoes in time and spac ....Modeling fluid flow and mineralisation at crustal interfaces. Several types of mineral resources, including some uranium, iron, and base metal ore deposits, may be created by fluid flow through and around interfaces in the Earth's crust. By understanding how, where and why such deposits form, we will assist exploration for future resources of these metals. Insights will also be gained into petroleum resource generation and extraction, the distribution of seismicity and volcanoes in time and space, the problems of underground nuclear waste disposal and sequestration of CO2, and the potential for geothermal energy, with benefits in resource identification and/or hazard assessment in these areas.Read moreRead less
Crustal Growth in the Northern Tasmanides. The Australian and Queensland governments have invested over $3 million to undertake deep crustal seismic imaging in northern Queensland, providing an extensive new geophysical dataset capable of modelling crustal architecture and geological evolution to unprecedented levels. However, such models will remain untested unless the data is groundtruthed by analysis of rocks at the surface, providing a geological framework for extrapolation into the deep Ea ....Crustal Growth in the Northern Tasmanides. The Australian and Queensland governments have invested over $3 million to undertake deep crustal seismic imaging in northern Queensland, providing an extensive new geophysical dataset capable of modelling crustal architecture and geological evolution to unprecedented levels. However, such models will remain untested unless the data is groundtruthed by analysis of rocks at the surface, providing a geological framework for extrapolation into the deep Earth. The framework critically describes when and how crustal blocks were assembled, and the integrated information will generate evolutionary 3D models that will substantially improve mineral exploration targeting in the region.Read moreRead less
CO2-brine behaviour in high temperature geological processes: Microanalysis and significance. This project clearly lies within the national research priority of developing deep earth resources. It may strengthen our economic fabric through mineral deposit discoveries in Australia as well as other circum-Pacific countries. The proposed research will also indirectly enhance our understanding of the relationships between geosphere, biosphere, fluids and global greenhouse warming.

It may strengthen our economic fabric through mineral deposit discoveries in Australia as well as other circum-Pacific countries. The proposed research will also indirectly enhance our understanding of the relationships between geosphere, biosphere, fluids and global greenhouse warming. By strong national and international collaborations and our use of innovative frontier technologies of fluid microgeochemistry, we will expand recognition of Australia's world-class research capacities.Read moreRead less

Summary
X-ray mapping and trace element electron probe microanalysis. The new advances offered by the acquisition of a state-of-the-art electron microprobe will provide multiple high-precision chemical and mineralogical data sets that will represent a breakthrough in our capacity to recognise scientifically important compositional micro-scale variations in geological, archaeological, biological and manufacured (metallurgical) materials.
Mineral Physics and Crystal Chemistry of Ni-Co-Laterite Deposits. Ni-Co laterite deposits host more than 50% of the mineable Ni-Co resources on the planet. Australia and Australian mining companies have been major producers of Ni and Co in the past. To continue to play a significant role in the exploration, production, and environmentally sound remediation of Ni-Co laterite mining sites, Australian mining companies must increase their understanding of the mineralogy of Ni-Co-deposits.
