The 2,940 line regional survey was flown east-west at 2.5 km nominal line spacing in 2021 by New Resolution Geophysics Pty Ltd (NRG) using the XCITE® airborne electromagnetic system. The Geological Survey of New South Wales commissioned the survey as part of the MinEx Cooperative Research Centre’s (MinEx CRC) National Drilling Initiative (NDI), the world’s largest mineral exploration collaboration. It brings together industry, government, research organisations and universities to further our understanding of geology, mineral deposits and groundwater resources in areas where rocks aren’t exposed at earth’s surface. The Geological Survey of New South Wales is a major participant in the NDI program, committing $16 million to the program over 10 years. In NSW, the program focuses on five areas in the state’s central and far west, where metallic minerals potentially exist under a layer of younger barren geology. These areas are North Cobar, South Cobar, Broken Hill (Mundi), Forbes and Dubbo. Geoscience Australia is also a major participant in the NDI, committing $50 million Australia-wide over the ten years of the MinEx CRC. Geoscience Australia partly funded the survey by providing funds for an additional 940 line kilometres of data acquisition to broaden the geographical reach of the survey under the Exploring for the Future Darling-Curnamona-Delamerian Project. Additionally, Geoscience Australia provided in-kind support to the project by managing the survey data acquisition and processing, undertaking the quality control of the survey and generating one of the two inversions and associated derived products that are included in the data package.
