Flight lines have been deliberately deviated to intersect geological points of interest, including outcrops, boreholes, locations with mineral occurrences and over areas with known kimberlite and meteorite impacts.into the hundreds of meters, allowing the identification of even subtle conductive features at depth.The data, inversions and survey details can be downloaded through Geoscience Australias catalogue at: https://ecat.ga.gov.au/geonetwork/srv/eng/catalog.search#/metadata/146042 or via the Geological Survey of Western Australias portal at: https://magix.dmirs.wa.gov.au/surveys/view-survey/3098 (survey notes) and https://geodownloads.dmp.wa.gov.au/downloads/geophysics/71588/ (data).Many thanks to the geophysical team at the Geological Survey of Western Australia for designing, planning and facilitating AusAEM20, along with their ongoing assistance with project management and stakeholder engagement. We are also truly appreciative of the dedication of the two contracting teams: Xcalibur and SkyTEM, for delivering such high quality data and for showing consideration to all stakeholders and executing the programme with zero safety incidents.Figure 3.Multi-plot presentation of the western end of Line 100901, AusAEM20 (WA).
