SOUTH AUSTRALIA (Spencer 80%, Minotaur Operations P/L 20%)

Background – location and geology

The titles comprising the Pandurra Project are located approximately 60km west of Port Augusta in South Australia. The Mesoproterozoic Pandurra Formation, a thick monotonous unit of unmetamorphosed, flat-lying arenaceous sediments, deposited on the central-eastern segment of the Gawler Craton, constitutes the main geology of the area. Northwest trending dykes of the Neoproterozoic Gairdner Dyke Swarm are common.

The titles lie within the Cariewerloo Basin and have potential for hybrid uranium mineralisation targets at several levels and depositional environments such as:

  • Associated with mafic dykes.
  • At the unconformity between Pandurra Formation and the overlying reduced Tapley Hill Formation.
  • At the unconformity between Pandurra Formation and the basement rocks.
  • Perched within the Pandurra Formation over unconformity- associated mineralisation.

In 2010, a detailed multidisciplinary investigation was commenced by PIRSA in collaboration with the Saskatchewan Ministry of Energy and Resources to assess the potential for unconformity associated uranium in the Pandurra Formation. This work is ongoing and Spencer anticipates that it will be able to leverage off this study in the future.

In July 2012 Spencer completed a helicopter VTEM time domain and magnetic survey (3 test lines).
