Together with geochemistry and geochronology programmes, the geoscience data acquisition will be analysed using artificial intelligence and machine learning techniques in addition to traditional interpretation methods to provide insight into underexplored parts of the state.Kate Robertson and Stephan Thiel Kate Robertson deploying a MT instrument byGeological Survey of South Australia, helicopter as part of the Curnamona Cube projectKate.Robertson2@sa.gov.au (photo taken by Samuel Jennings).
