The outcrop geology within EL 3852 Cariewerloo consists predominantly of Pandurra Formation of the Cariewerloo Basin that unconformably overlies Gawler Range Volcanics. Archer Exploration considers the tenement prospective for the discovery of unconformity style uranium mineralisation.
The magnetic data indicates a possible northwest southeast trending basement structure extending through the tenement. If this structure can be confirmed, it will provide a focus for exploration for uranium mineralisation at the Pandurra Formation - Gawler Range Volcanics unconformity.
