An area situated about 60 km west of Coober Pedy is being explored for possible economic iron oxide - associated copper-gold deposits hosted within Palaeoproterozoic basement rocks of the Mabel Creek Gravity High. A tectonic re-interpretation of the gravity and aeromagnetic data available for this area indicates that up to four strongly-developed structural deformation systems are present. These are WNW, NW, ENE and NE - trending features, which determine the overall structural complexity and geological setting of possible mineralisation. The basement lithologies of the Mabel Creek High intersected in previous drilling include granite, gneiss and banded iron formation which are correlated with similar rocks that comprise the Mount Woods Inlier, and which form the sequence hosting the Prominent Hill IOCG deposit. Work carried out by Minex and Marathon within the now relinquished licence portion consisted of the acquisition of gravity readings at 394 stations to extend the regional gravity coverage westwards.
