A total of 37,806 line kilometres of airborne gravity data were acquired using SGL’s airborne gravity system, Airborne Inertially Referenced Gravimeter (AIRGrav). The survey was funded by the Department of Mines, Industry Regulation and Safety (DMIRS) Western Australia, and managed by Geoscience Australia. The data were peer reviewed by airborne gravity expert Dr Mark Dransfield contracted by Geoscience Australia. The data from this survey were released by the Geological Survey of Western Australia and can be downloaded from MAGIX under reference 71156.
