A very small, ~90 square km licence area centred ~40 km south-east of Coober Pedy is being explored for possible economic IOCG or other types of metallic mineralisation that may have formed in concealed Proterozoic basement rocks. During the first licence year, on 9/5/2007, IMX Resources flew a detailed helimag airborne magnetic survey totalling just 3.101 line km to cover EL 3830 along flight lines that were 50 m or 100 m apart, using a sensor mean height above the ground surface of 20 m. The survey was intended to outline possible BIF horizons which might have magnetite iron ore potential. In May 2008, the company drilled a single vertical RC hole of 112 m depth to test the WS22 gravity anomaly located north-west of Cairn Hill, which it was thought might represent palaeochannel sediments with possible sedimentary uranium potential. 18 x 4-metre drill cuttings composite samples were assayed for a 22 element suite, and were logged for radioactivity using a hand-held scintillometer. Three water wells were rotary mud drilled at sites adjacent to the Cairn Hill mine export haul road to look for groundwater supplies (to use for then current road construction and for ?future dust mitigation). The holes were terminated upon reaching solid bedrock. Drill cuttings from these holes were logged by IMX. No exploration work was done during licence Year 2, but construction of the haul road from the Cairn Hill mine was completed, including an underpass which was built beneath the existing Stuart Highway that runs along the licence's western boundary. 30% of the original licence area was partially relinquished in June 2009. During licence Year 3, in May 2010, joint venture partner OZ Minerals acquired a small part, 349.4 line km, of a large Falcon airborne gravity gradiometer survey that was flown over most of the Mount Woods Project area. The AGG data were acquired along flight lines 200 m apart, using a mean sensor height of 80 m above the ground surface. A preliminary dataset only has been received by the end of the reporting period. It confirmed an interpretation which IMX had made from the previously-acquired helimag magnetic data: that there is a major geological boundary running approximately E-W across the centre of the Mount Brady EL 3830. Basement rocks in the southern portion of the EL have been down-faulted relative to those in the northern half. The airborne gravity gradiometer data also emphasised the presence of major ENE- and NNW-trending lineaments, besides defining some broadly coincident gravity and magnetics features, but also revealing several gravity anomalies that do not coincide with magnetic highs. During licence Year 4, no field work was done because activities were focussed on other parts of the Mount Woods Project acreage; however, the airborne gravity and magnetic data were fully processed.
