Project Total: $254,314; This research project aims to test and develop geological and geochemical vectors to low sulfidation epithermal gold mineralization in the Cerro Negro district of Argentina. The project will integrate Terraspec and XRD analyses of clay mineralogy (illite, smectite, kaolinite) with vein textures and, where available, whole rock and mineral geochemistry to help constrain the relative depths of vein segments within discrete fault blocks and proximity to ore. Funded by: Oro Plata S.A. ($254,314); University of Tasmania.

Project Total: $164,000; The aims of this project are to examine the surface geology, open pits/trenches, drill core and computer database at San Sebastian in order to:  Determine the relationship between the San Sebastian, Pedernalillo, La Roca, and other ungrouped vein systems and occurrences within the Saliadillo Mining District.  Characterise the host rock sequence lithologies and controls on vein development.  Undertake a structural analysis of data from mapping, pits, drillcore, and trenches to understand structural controls on vein formation  Characterize whole rock and trace element geochemistry of veins, vein stages, host rock, volcanics, and alteration in order to develop potential vectors toward mineralization  Date, using a range of geochronological methods, veins, vein stages, host rock, volcanics, and alteration.  Undertake fluid inclusion analyses on suitable minerals in the veins to determine fluid characteristics and controls on ore deposition  Obtain isotope (O-H, S, Pb) data to gain additional information on fluid origin and evolution  Compilation of data into a 3d model.  Test existing ore genetic models and provide, if necessary, an improved genetic model for the San Sebastian vein deposist.  Develop useful criteria for exploration in the Saladillo district.

Project Total: $6,924; This topical study, investigates the crystallization history of volcanic stratigraphy of the Myra Falls volcanic-hosted massive sulfide (VHMS) district of central Vancouver Island, British Columbia, Canada. Mineralization occurs at two stratigraphic horizons in volcanic strata of the mid-Paleozoic Sicker Group. Previous dating studies at Myra Falls have yielded relatively imprecise crystallization ages. Major research objectives are to establish crystallization ages for the host rocks and the temporal relationships between the two horizons. The author has conducted two field programs at Myra Falls with detailed drill hole examinations completed, and suitable samples obtained to conduct this study.

Project Total: $1,600,000; Grade by size fractionation has been recognised in a number of deposits. The challenge is to recognise what aspects of ore mineralogy and texture lead to the development of significant grade by size fractionation. A predictive understanding of this process will significantly aid the recognition of suitable rock masses for grade engineering. The aim is to produce a predictive model for grade by size fractionation that reaches TRL 4. Funded by: CRC for Optimising Resource Extraction ($1,600,000); University of Tasmania.

Project Total: $12,756,508; The ARC Research Hub for Transforming the Mining Value Chain will make significant improvements to industry practices along the mining value chain. These changes will enhance ore deposit discovery, mineral processing, and environmental management of ores and waste materials. The Hub will bring together a team of world-class researchers, industry partners and research facilities to deliver end-user driven solutions that are critical to improving profitability and productivity in Australia's mining industry.

Project Total: $165,000; The aims of this project are to examine the surface geology, underground workings, drill core and computer database at Myra Falls in order to: characterise the geologic and structural setting of the West Block area; describe the deposit mineralogy, textures, paragenesis and metal zoning in the West Block area; determine the geochemical (trace elements, stable isotopes) characteristics and signature of the mineralisatuon and alteration; propose a model for the genesis of the VHMS deposits in the West Block area and compare them to other deposit in the Myra Falls District; develop useful criteria for exploration in the Myra Falls District.
