The southern Thomson Orogen is a poorly understood crustal element of northwestern New South Wales and Queensland. The Southern Thomson Project, a joint research project between Geoscience Australia, the Geological Survey of New South Wales and the Geological Survey of Queensland, is improving mineral systems understanding of this under-explored orogen to encourage mineral exploration investment. The Project includes new pre-competitive geological and geophysical data collection and interpretation to inform stratigraphic drilling of strategic crustal elements within the southern Thomson Orogen. Two AEM surveys were flown in 2014 and 2016, respectively. Results from these were interpreted using available stratigraphic borehole data and surface geological mapping to produce a new cover thickness model of the area that is used to interpret target depths for the stratigraphic drilling, and to inform on the validity of other pre-drilling geophysical methods. This presentation presents highlights of the AEM data and discusses its implications for mineral exploration as well as long-term landscape evolution, neotectonism within the Eromanga and Lake Eyre basins and hydrostratigraphic unit mapping within the region. Results of the modelling will demonstrate that large portions of covered ground are within reach of exploration drilling.
