b'Geophysics in the surveysNewsthe Mount Isa Province (Figure 2). The survey expands MT coverage to the north and west of the 2016 Cloncurry MT survey.The survey was funded by the Queensland Governments Strategic Resources Exploration Programme, which aims to support discovery of mineral deposits in the Mount Isa Region.The survey area is predominantly covered by conductive sediments of the Carpentaria Basin. The cover thickness ranges from 0 m in the extreme south west of the survey, to over 345 m in the north.Acquisition started in August 2019 and was completed in late October 2020 by Zonge Engineering and Research Organization. Data were collected at 2 km station spacing on a regular grid with a target bandwidth of 10 4103 s. Instruments were left recording for a minimum of 24 hours unless disturbed by animals. The low signal strength posed a significant impediment for acquiring data to 1000 s, even with the 24-hour deployments. Almost all sites have data to 100 s, with longer period data at numerous sites. Data are due for release by the end of December and will be available on the open data portal.Matthew Greenwood, Janelle Simpson and Roger Cant Geological Survey of Queensland Geophysics@dnrme.qld.gov.auFigure 2.Location of the Cloncurry Extension MT survey over a composite TMI and TMI 1VD magneticimage.DECEMBER 2020 PREVIEW 24'
