Finding Porphyry Copper with zircon trace elements & hyperspectral display. Copper mine discovery rates lag behind world needs. One way to find copper in the World’s Ring of Fire is to measure compositions of zircons which are durable minerals concentrated in stream sands and spreadout long distances below a deposit. 100s of zircon from a cup of sand constitute a sample. Zircon chemical features that indicate possible mines are mostly understood, but nature is complicated. Beyond the 26 channel ....Finding Porphyry Copper with zircon trace elements & hyperspectral display. Copper mine discovery rates lag behind world needs. One way to find copper in the World’s Ring of Fire is to measure compositions of zircons which are durable minerals concentrated in stream sands and spreadout long distances below a deposit. 100s of zircon from a cup of sand constitute a sample. Zircon chemical features that indicate possible mines are mostly understood, but nature is complicated. Beyond the 26 channels of chemical data for each grain in the 10,000s of analyses, there are 7 layers of lab imaging data that are not carried along in a convenient way. Geologists need smart computer systems to find useful relationships among the 33 channels and to discover relations within and between samples to find more mineable copper. Read moreRead less
In the Driver's seat: role of trace elements in enabling crustal fluid flow. This proposal aims to systematically investigate the role of trace elements in controlling the kinetics, product composition, and feed-back between fluid flow and the reaction interface, in fluid-driven mineral reactions. This project expects to provide a framework for the integration of activator trace elements in models of crustal fluid flow and their application in the recovery of base, precious, and critical metals, ....In the Driver's seat: role of trace elements in enabling crustal fluid flow. This proposal aims to systematically investigate the role of trace elements in controlling the kinetics, product composition, and feed-back between fluid flow and the reaction interface, in fluid-driven mineral reactions. This project expects to provide a framework for the integration of activator trace elements in models of crustal fluid flow and their application in the recovery of base, precious, and critical metals, using interdisciplinary approaches across geochemistry, mineral engineering and material sciences. Expected outcomes include improved prediction of the transport of metals and fluids in geo-systems. This should provide significant benefits towards integrating the mineral value chain from exploration to mining and metallurgy.Read moreRead less
Experimental constraints on the genesis of gold-rich ore deposits. The project will provide a new set of tools to explore for gold-rich ore deposits in Australia and globally. By integrating geochemical studies with cutting-edge experiments carried out at three Australian universities in strategic partnership with industry, the outcomes of this project will provide much needed knowledge to predict the locations of large gold-rich deposits that are concealed beneath vast expanses of the Australia ....Experimental constraints on the genesis of gold-rich ore deposits. The project will provide a new set of tools to explore for gold-rich ore deposits in Australia and globally. By integrating geochemical studies with cutting-edge experiments carried out at three Australian universities in strategic partnership with industry, the outcomes of this project will provide much needed knowledge to predict the locations of large gold-rich deposits that are concealed beneath vast expanses of the Australian continent. The new results will translate into smarter exploration practice, significantly enhancing success in targeting ore deposits that are rich in high-value metal and display the smallest have a small environmental footprint, to underpin the sustainability of our nation into the future.

Aqueous fluids in the deep earth. This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic mod ....Aqueous fluids in the deep earth. This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic models, the more reliable predictions will provide a more realistic assessment of the role of sulphur in controlling metal endowment and atmospheric chemistry through geological times. This should provide a useful guide for mineral exploration and planetary science.Read moreRead less
The lost ocean of eastern Australia and its critical metals endowment. This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial ....The lost ocean of eastern Australia and its critical metals endowment. This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial knowledge gap in Australian tectonics, while providing information on ore mineralisation. The expected outcomes, including new tectonic models unveiling the scale, geometry, and economic potential of the ultramafic bodies, could benefit critical mineral exploration, carbon storage solutions, and geoecology conservation.Read moreRead less
Exploring volcanic arcs as factories of critical minerals. Volcanoes at destructive plate boundaries (magmatic arcs) host most global copper deposits, critical for renewable energy and in unprecedented rising demand. This project aims to use high-resolution geochemical zoning of erupted crystals to uncover how magmatic processes lead to copper mineralisation and explosive volcanic eruption in arc volcanoes. The expected outcome is new knowledge on the inner workings of volcanoes and their copper ....Exploring volcanic arcs as factories of critical minerals. Volcanoes at destructive plate boundaries (magmatic arcs) host most global copper deposits, critical for renewable energy and in unprecedented rising demand. This project aims to use high-resolution geochemical zoning of erupted crystals to uncover how magmatic processes lead to copper mineralisation and explosive volcanic eruption in arc volcanoes. The expected outcome is new knowledge on the inner workings of volcanoes and their copper enrichment potential. Anticipated applications are refined exploration targeting for copper and improved volcano hazard assessment. This will benefit the Asia-Pacific region and enhance the capacity of mining companies in the global race to produce metals of the future.Read moreRead less
