Where to find giant porphyry and epithermal gold and copper deposits. This project will determine when and where giant gold or copper deposits should form, consolidating links with Indonesia, and using South East Asia as a vast natural laboratory in which to examine the effect of large-scale tectonic processes. The project will produce a four-dimensional virtual exploration toolkit to show how to apply the methods.
Four dimensional lithospheric evolution and controls on mineral system distribution in Neoarchean to Paleoproterozoic terranes. This project will resolve important questions about the links between the evolution and preservation of continents and important mineral deposits in Australia and West Africa between 2.7 and 1.8 billion years ago. The results will improve the understanding of a key period of Earth history and make a major contribution to mineral exploration.
Advancing Mineral Exploration Models for Orogenic Gold Deposits. This interdisciplinary project links geochemistry with crustal-scale fluid migration, aiming to improve mineral exploration success for orogenic gold deposits. In doing so, it intends to provide a more holistic view of gold deposit genesis. This project plans to focus on the Victorian goldfields, which have world-class historic gold production, an existing seismic transect, and a geologic setting that will address key problems in g ....Advancing Mineral Exploration Models for Orogenic Gold Deposits. This interdisciplinary project links geochemistry with crustal-scale fluid migration, aiming to improve mineral exploration success for orogenic gold deposits. In doing so, it intends to provide a more holistic view of gold deposit genesis. This project plans to focus on the Victorian goldfields, which have world-class historic gold production, an existing seismic transect, and a geologic setting that will address key problems in gold deposit genesis. A series of modelling techniques will be used to marry structural and geochemical aspects of gold deposit formation at a scale that has not been previously attempted.Read moreRead less
Magma dynamics and ore deposits. This project aims to advance knowledge on magma transport mechanisms through the Earth’s lithosphere, and boost predictive capacity to discover new ore deposits. Using field surveys, three-dimensional reflection seismic data, laboratory experiments and rock fracture mechanics, this project will investigate where, how and why, narrow finger-like conduits form in lithosphere-scale magma plumbing systems. The project expects to generate new knowledge on the formatio ....Magma dynamics and ore deposits. This project aims to advance knowledge on magma transport mechanisms through the Earth’s lithosphere, and boost predictive capacity to discover new ore deposits. Using field surveys, three-dimensional reflection seismic data, laboratory experiments and rock fracture mechanics, this project will investigate where, how and why, narrow finger-like conduits form in lithosphere-scale magma plumbing systems. The project expects to generate new knowledge on the formation and location of highly valuable ore deposits of nickel, copper, cobalt and platinum group elements, which are preferentially trapped in poorly understood, finger-like magma conduits. Anticipated outcomes of the project include fundamental insights into how magma transport dynamics control traps for magmatic sulfide ores as well as equipping mineral explorers in targeting their search for these important, but hard to find, ore deposits, benefitting society through future discoveries of economically strategic, new commodities.Read moreRead less
Multiscale dynamics of ore body formation. Future discoveries of giant ore-bodies will undoubtedly be under surface cover. Modelling of new data from South Australia and Western Australia will define targeting criteria for new major ore-bodies, thus exploiting Australia's deep earth resource potential. New understanding of controls on mineralisation decrease exploration risk. Ore-bodies, such as Olympic Dam, have made major contributions to Australia's economy over past decades and promise to ad ....Multiscale dynamics of ore body formation. Future discoveries of giant ore-bodies will undoubtedly be under surface cover. Modelling of new data from South Australia and Western Australia will define targeting criteria for new major ore-bodies, thus exploiting Australia's deep earth resource potential. New understanding of controls on mineralisation decrease exploration risk. Ore-bodies, such as Olympic Dam, have made major contributions to Australia's economy over past decades and promise to add increased value over future decades. This project enhances the probability that at least one other ore-body of this type will be discovered. Such discoveries contribute directly to the wealth of Australia through export earnings and accelerate the development of regional infrastructure and new technological development.Read moreRead less
Defining the multi-scale controls on high-grade gold mineralisation. This project aims to improve our understanding of how extremely high-grade gold occurrences form in order to further our understanding of metal transport and accumulation within the Earth’s crust.

This project aims to improve our understanding of how extremely high-grade gold occurrences form in order to further our understanding of metal transport and accumulation within the Earth’s crust. This project will generate new knowledge in the area of gold geochemistry using novel experimental programs, interdisciplinary approaches and by utilising advanced technologies. Expected outcomes of this project include reducing the unpredictability of high-grade gold occurrences that impact both production and exploration strategies. This project should benefit the mineral industry partners by helping to discover high grade gold resources which is of great benefit to Australia.Read moreRead less

Geological controls on high-grade oreshoots in the Wallaby gold deposit, Western Australia: Understanding the role of magmatic fluids in an Orogenic Au system. This project aims to understand the geological controls on high-grade (>2 g/t Au) oreshoots at the world-class Wallaby gold deposit (>7 Moz Au). In particular, the role of magmatic fluids in the transport and deposition of gold will be investigated.

This project aims to understand the geological controls on high-grade (>2 g/t Au) oreshoots at the world-class Wallaby gold deposit (>7 Moz Au). In particular, the role of magmatic fluids in the transport and deposition of gold will be investigated. The Wallaby gold deposit is an ideal natural laboratory to investigate the complex relationship between the geometry and timing of faults, influx of multiple hydrothermal fluid events and the deposition of gold. In particular, the study will investigate the relative importance of intrusion-related, and fault zone-related events in the formation of high-grade ore shoots. The outcomes of this study will include a clear understanding about the timing and relative contribution of magmatic and fault zone related events and their significance to the formation and geometry of high-grade oreshoots.Read moreRead less
Tectonic evolution and lode gold mineralisation in the Southern Cross district, Yilgarn Craton (Western Australia): a study of the meso- to Neoarchaean missing link. In the December quarter 2008, Gold export earnings increased by 2 per cent to $3.9 billion. Over the past 20 years and despite an increase in exploration expenditure to around $50 million per year, the discovery rates have been declining. Although the easy targets have been found, there remains considerable potential for future ma ....Tectonic evolution and lode gold mineralisation in the Southern Cross district, Yilgarn Craton (Western Australia): a study of the meso- to Neoarchaean missing link. In the December quarter 2008, Gold export earnings increased by 2 per cent to $3.9 billion. Over the past 20 years and despite an increase in exploration expenditure to around $50 million per year, the discovery rates have been declining. Although the easy targets have been found, there remains considerable potential for future major discoveries. This project addresses the pressing need for new data and improved exploration techniques to enable industry to target new discoveries. As the Southern Cross district is located in remote communities such discoveries also have major benefits for regional Australia.Read moreRead less
