Unearthing the hidden riches
RESEARCHERS have developed new methods for recognising potential mineralisation hidden beneath barren cover rocks in under-explored areas of WA. A major collaboration between the Minerals Research Institute of Western Australia (MRIWA), the Centre for Exploration Targeting (CET) and sponsor Gold Road Resources, the project seeks to apply new computational technology to solving the challenges of mineral exploration below barren cover rocks. The work targeted WA’s Eastern Yilgarn Craton and Albany-Fraser Orogen, where highly-endowed regional geology known to host world-class mineral deposits is buried and hidden from view by later sediments. Led by geophysicist Mark Lindsay at the University of WA, the CET research team developed innovative processing techniques to improve the quality of conventional geophysical constraint, and applied cutting-edge machine...
