Jaguar is a remarkably pristine finely banded submarine volcanic hosted base-metals-silver deposit from the Australian Archean, ~2.7 billion years old. We will document its detailed ore and volcanic textures, gaining valuable new genetic insights from its extraordinary preservation. With an emerging mining company in regional Western Australia, we will combine forensic textural studies with advanced geochemical analysis to (1) determine the deposit origin; (2) infer the origin of other well laminated but less well preserved deposits globally; (3) apply these findings to the detection of local prospective horizons under deep cover; and (4) use the deposit features to test current models of massive sulfide formation.Read moreRead less

This project will leverage new advances in analytical instrumentation and isotope techniques to generate improved geochronological and stratigraphic framework for the Centralian Superbasin, a vast ancient depositional system covering much of central Australia. The project aims to apply novel laser-based dating of sedimentary rocks, coupled with metal isotope proxy reconstructions of the basin’s palaeogeography, hydrological connectivity and past redox conditions, which are all critical parameters to guide and de-risk future exploration of sediment-hosted resources in this frontier basin. Anticipated outcomes will benefit Australia's resources economy, while providing insights into the evolution of Earth’s surface environment in deep time.Read moreRead less

Geochronology, Metallogenesis and Deposit Styles of Loei Foldbelt in Thailand and Laos PDR. The Loei volcanic-plutonic belt occurs in Thailand and Laos PDR between two major crustal terranes in mainland SE Asia: Shan-Thai in the west and Indochina terrane in the east. Several skarn type copper-gold and porphyry related epithermal gold deposits are distributed along the Loei belt, and yet these deposits are not well documented in the literature.

The Loei volcanic-plutonic belt occurs in Thailand and Laos PDR between two major crustal terranes in mainland SE Asia: Shan-Thai in the west and Indochina terrane in the east. Several skarn type copper-gold and porphyry related epithermal gold deposits are distributed along the Loei belt, and yet these deposits are not well documented in the literature. Detailed metallogenic relations and evolution of these mineral deposits are also poorly understood; it is not known whether they formed from single, long-lived intrusive-centred mineralised systems or multiple/episodic mineralised systems. Understanding the geotectonic and metallogenic relations of this belt have a direct benefit to Australian companies exploring in SE Asia, and the research results also can be applied back in Australia for exploration of Cu-Au deposits.Read moreRead less
Geologic, genetic and exploration implications of syndeformational, structurally-controlled, sediment-hosted copper deposits: investigation of the Mt Oxide deposit, Queensland. This project will use a multi-disciplinary approach to understand the geology, geochemistry and genesis of the syndeformational, structurally-controlled, sediment-hosted copper mineralisation at the Mt Oxide deposit, Queensland.

This project will use a multi-disciplinary approach to understand the geology, geochemistry and genesis of the syndeformational, structurally-controlled, sediment-hosted copper mineralisation at the Mt Oxide deposit, Queensland. Copper deposits, like Mt Oxide, are an important exploration target in sedimentary basins but their characteristics and formation are poorly understood. Discovery of further sediment-hosted Cu deposits is imperative as Australia's industrial competitivness in exploration and mining depends on the discovery of new ore depsoits. This project specifically addresses the need for better genetic and exploration models for copper deposits concealed within ancient, deformed sedimentary sequences in Australia and overseas.Read moreRead less
Origin and setting of Congolese-type Cu deposits. This project aims to understand the genesis of the giant sediment-hosted Cu ore deposits of the Congolese Copperbelt, and their relationship to the enclosing strata. We will use selected study areas within the correlative Neoproterozic basin successions in Australia, which are well exposed and covered by modern geoscientific datasets, as analogues for the poorly exposed Congolese system. Once this is achieved, we will combine the results with tho ....Origin and setting of Congolese-type Cu deposits.

We will use selected study areas within the correlative Neoproterozic basin successions in Australia, which are well exposed and covered by modern geoscientific datasets, as analogues for the poorly exposed Congolese system. Once this is achieved, we will combine the results with those of a previous ARC linkage project on the nearby Zambian Copperbelt, to provide the first integrated model of the worlds largest sedimentary Cu system.Read moreRead less
What controls trace element levels in ore sulfides? A laser-ICPMS perspective. Sub-surface hydrothermal gold and base metal orebodies are surrounded by aprons of elevated metal concentrations, mainly within micro-sulfides, which is one sign mineral explorers use to widen their target. Here we test whether the hostrock contributes metal in the most distant parts of such halos, and if so, what factors control where hostrock metal begins to be detectable in a given system. We will make better model ....What controls trace element levels in ore sulfides? A laser-ICPMS perspective.

Here we test whether the hostrock contributes metal in the most distant parts of such halos, and if so, what factors control where hostrock metal begins to be detectable in a given system. We will make better models of how metalliferous waters react with rock, potentially translating into million dollar savings through more efficient exploration. The ultrafine sampling and precision analyses required for this are possible because of an ARC-funded core program at CODES.Read moreRead less
