An area located near Stansbury on southern Yorke Peninsula is being explored for possible buried sandstone-hosted sedimentary uranium deposits that may have been formed in the Tertiary and Permian strata, and also for possible unconformity-related uranium deposits which could have formed at the base of the Permian and Cambrian sedimentary sequences, in proximity to known uraniferous granitic basement rocks and major fault structures. No exploration has been conducted on the currently relinquished portion of EL 3907, where the basement is expected to lie at > 1 km depth, and where it was thought that gaining on-ground access for uranium - related activities was likely to be prevented by social land usage factors.
