July 2020: The data in this product has been superseded, with the new dataset available here: https://pid.geoscience.gov.au/dataset/ga/133388 However, the report in this product still presents valuable insights e.g., into the relationship between copper in the regolith and groundwater. The mineral resources of Tennant Creek and Mt Isa have contributed tremendously to the economic development the Northern Territory and Queensland. Vast areas of poorly known mineral potential remain under explored between and around these two mining centres, with prospective solid geology covered by a relatively thin layer of transported sediments. Hydrogeochemical surveys utilise groundwater as a passive sampling medium to reveal the chemistry of the underlying geology including hidden mineralisation. These surveys also provide regional baseline groundwater datasets that can inform environmental monitoring and decision making.
