In 2019, data acquired under Geoscience Australia’s $100m “Exploring for the Future” program revealed a lithospheric connection between the Tennant Creek and Mt Isa mineral fields. In particular, previously unrecognised major features favourable for hosting large mineral systems were seen in the East Tennant region. A moratorium on Exploration Licence Applications was placed over the region and a competitive tender process flooded with applications from exploration companies. SER won key ground in this process.

In 2020, SER conducted an extensive and detailed ground gravity survey over our ground and together with Arrow Geosciences (led by former Chief Geophysicist for Rio Tinto, Theo Aravanis) processed all available geophysical data, interpreted the results and generated Cu-Au targets. Since then, neighbouring Explorers have started to uncover secondary copper mineralisation in cover sequences providing further evidence of the prospectivity of the region.

On 17 December 2020, the Mineral Exploration Cooperative Research Centre (MinEx CRC) announced the completion of the 10 hole, 4000m National Drilling Initiative (NDI) regional stratigraphic drilling campaign in the East Tenant region. The aim of the drilling is to assess the mineral potential of basement rocks and the results (expected this quarter) are eagerly awaited by SER and many other explorers.
