Three separate licence areas located within 50 km of Olympic Dam, and a fourth (Halifax Hill) located 150 km north-west of there, have been explored for possible economic buried IOCG-U mineralisation that may be hosted by Mesoproterozoic basement rocks overlain by generally flat-lying Mesoproterozoic to Phanerozoic sediments of the Stuart Shelf. During the first year of tenure, work completed included: - researching and negotiating legal access for the three tenements that fall within either the WPA Amber 1 or Green Zones. EL 3679 Playford South-east had the most restrictive access conditions applied to it time-wise; - production of 1:250,000 scale magnetic and gravity images over EL 3866 Chinaman Hat Hill by contractor Southern Geoscience, which revealed an untested coincident gravity and magnetic anomaly in the southern part of the tenement; - inversion modelling by Geo Discovery Group of the gravity and magnetic data for EL 4437 Halifax Hill, which showed that infill gravity surveying is required before any drill targets can be discerned; and - reprocessing by GeoDiscovery Group, using UBC inversion algorithms, of all the available geophysical data from the never drilled area EL 4438 Lake Torrens East. Probable sources to the principal modelled gravity and magnetic anomalies were indicated to lie at >2 km depths below the surface. During the second year of tenure it appears, from some information much later on provided to DMITRE in a company director's brief explanatory letter, that no work was done on any of the subject tenements. After Straits left the joint venture, licensee UXA allowed tenure of ELs 4437 and 4438 to lapse on 15/2/2012; tenure of EL 3866 was allowed to lapse on 29/7/2012; and tenure of EL 3679/4928 was allowed to lapse on 17/12/2013.
