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

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.

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
A microscopic and analytical study of extreme thermophile bacteria in simulated environments compared to organic matter in early Earth hydrothermal systems.

The study will examine microbial cells and organic residues of cultured thermophilic archaea from simulated extreme environments in terms of temperature, pressure and mineral concentrations. These will be compared, applying observational and geochemical techniques to organic material in geologically earliest ecosystems. A novel approach will be adopted, of 'backtracking' changes occurring to cultured microbial cells towards their breakdown and disintegration (in contrast to the more common approach of simulating synthesis of organic compounds as a starting point towards structured functioning organisms), and their viability limits. The results of the study will be tested within the currently available theoretical models for the origin of life.Read moreRead less
Fluid mixing in hydrothermal systems. Mixing of fluids within permeable rocks can cause significant chemical changes to the fluids and the rocks, for example it causes metals to be dissolved and transported. Accumulation into mineral deposits requires concentration mechanisms which are uncertain due to difficulty of detecting ancient fluid pathways. We will analyse these ancient fluids using new microanalytical and other combined techniques, thereby testing the role of fluid mixing as a mechanis ....Fluid mixing in hydrothermal systems. Mixing of fluids within permeable rocks can cause significant chemical changes to the fluids and the rocks, for example it causes metals to be dissolved and transported. Accumulation into mineral deposits requires concentration mechanisms which are uncertain due to difficulty of detecting ancient fluid pathways. We will analyse these ancient fluids using new microanalytical and other combined techniques, thereby testing the role of fluid mixing as a mechanism for efficient metal precipitation. The research has significance for exploration and models for mineral deposits, and for characterising other geological fluids, and provides opportunity for technical breakthroughs in microanalysis of fluid inclusions.Read moreRead less
