Waters of Jericho: Characterizing the Cu isotope compostition of water overlying IOCG-style deposaits in the Mt Isa block (Jericho and Eloise deposits)

Indicative Funding: $41,000 over 2 years
Summary: This project is a pilot study that aims to characterize the Cu isotope compositions of borehole waters in 10 km radius around the Jericho and Eloise IOCG type ore deposits. Cu isotopes can act as an ore vectoiring. However, few studies have focused exclusively on natural water samples as a ameans to vector under cover. Novel, efficient techniques are needed as the demand for Cu increases with population and our transition to green energies. A second aim of the project is to stream line the purification of Cu (needed for analysis) to make this more time and cost efficient, and thus more accessible to industry partners.
