South Australia

In South Australia the Company holds sixteen granted exploration licences totalling 6,218 km2 of prospective ground. Three of the granted exploration licences are part of the joint venture with RIL Australia Pty Ltd.

Exploration Targets – Stuart Shelf

In South Australia the Company is exploring in the Stuart Shelf area for haematite breccia complex deposits (also known as Iron Oxide Copper Gold Uranium or “IOCGU” deposits) of which the Olympic Dam mine, the world’s largest uranium resource, is the type example. In most places on the Stuart Shelf the rocks which host the haematite breccia complex deposits are buried under varying thicknesses of later sediments.

In some extreme cases, where the Cariewerloo Basin overlies the Gawler Craton, the depth to prospective horizon may be in excess of 1,000 metres in depth. Because of the “blind” nature of the targeted haematite breccia complex deposits on the Stuart Shelf, geophysics (principally gravity and magnetics) has been extensively used to define drill targets. Olympic Dam, Prominent Hill and Carrapateena were all discovered in this way.Past exploration by UXA on the Stuart Shelf has included the drilling of two deep diamond drill holes, testing geophysical targets on Winjabbie EL 3432. Copper mineralisation was encountered in drill hole 07WJ01 from 825m depth including a 42m interval grading 0.34%. This mineralisation is similar to that found by earlier explorers in the area in drill holes SAE 11 and WJD 1 (Figure 2).

The significance of this mineralisation is being reviewed as part of UXA’s broader review of its Stuart Shelf projects.



Based on data provided by the Department of Primary Industries & Resources South Australia (PIRSA), the Company has identified several coincident magnetic and gravity anomalies on the Stuart Shelf as potentially prospective for haematite breccia complex deposits and has acted quickly to acquire exploration rights covering these anomalies.
