An area within the northern Stuart Shelf which extends from 15 to 65 km south of the Prominent Hill mine site has been explored for possible similar IOCG-U type economic mineral deposits by a new industry entrant uranium explorer, Uranium Exploration Australia. During November-December 2005, part of a 6612 line km regional low-level airborne magnetic/radiometric survey (200 m north-south flight line spacing, 50 m mean terrain clearance) was flown across the subject licence, and resulting geophysical anomalies of interest were followed up with almost 1000 ground scintillometric scans, plus geological prospecting and soil geochemical sampling (83 samples). A 100 square km anomaly lying just to the north of Sloane Hill was interpreted as reflecting a major basement-penetrating east-west fault, with some associated anomalous surface radioactivity regarded as possibly being due to the transit of uranium-bearing fluids up this fault. During April-May 2006, a first round of broadly-spaced exploratory drilling (2 diamond core holes for 400.3 m of total penetration, plus 2 RC holes totalling 391.3 m) was carried out at this prospect, which indicated moderate core sample anomalism in silver and tungsten (but could be ?diamond drill bit contamination) in Cretaceous and Permian cover sediments at relatively shallow depths of between 30 and 112 m. However, no significant mineralisation was found in the underlying Mesoproterozoic basement metasediments. Six vertical percussion water wells previously drilled by Oxiana to supply the Prominent Hill mine were also sampled and logged radiometrically. In further investigations of the sizeable Sloane Hill surface radiometric, magnetic and gravity anomalies, two infill drilling programmes were conducted. The first, performed during October-December 2006, consisted of 10 rotary precollared diamond and separate aircore or RC drill holes: SH5/SH5a, SH6 - SH12, SHT1 and LH1 (comprising 1042.4 m of rotary mud, 608 m of aircore/RC, and 147.5 m of HQ plus 1243.1 m of NQ diamond core penetration). SHT1 was designed to twin hole SH1 from the previous drilling campaign, in an effort to verify the reports of anomalous silver in drillcores. Since no elevated silver assays were encountered in SHT1, the anomalous silver is now believed to come from sample contamination. Only hole SH7 showed evidence of significantly elevated uranium assay values, encountering patchy uranium mineralisation to 68 ppm U over the depth interval 504-508 m within oxidised Pandurra Formation. The second programme, undertaken during July-August 2007, consisted of the diamond drilling of a single new hole (07SH13) and the extension of diamond cored hole SH7. Hole 07SH13 was designed to test the location of an interpreted fault, which, together with surface radiometric anomalies, was thought to have been deposited by the migration of fluid through the fault zone. The hole was drilled to a depth of 702.2 m before rig capacity was exceeded, thereby terminating the hole in the Pandurra Formation prior to reaching basement. Three drill core intervals with both elevated scintillometer readings and uranium assay values correspond to bleached, crumbly sections within Pandurra sandstone units, and these features have been taken to represent the effects of the former passage of hydrothermal fluids and of structural deformation. An attempt was made to extend hole 07SH13 to try to reach basement and to determine that drill site's potential for unconformity style uranium mineralisation. The rig was unable to successfully re-enter 07SH13, and therefore was instead used to deepen hole SH7 beyond the 805 m depth achieved in the previous drilling programme, to further investigate slightly elevated but variable uranium returned from drill core assays. Accordingly, hole SH7 was deepened to 1212 m, whereupon drill rig capacity was once again exceeded. As for 07SH13, the hole once again terminated in the Pandurra Formation without reaching basement. Following an hiatus in drilling caused by contract default on the part of a contractor, hole SH7 was again deepened using a higher capacity rig hired from a different company, with a new total depth of 1467.5 m being achieved. Basement, consisting of granitic rock, was reached at a depth of 1427 m (Note: samples of this basement were submitted for whole rock geochemical analysis, but the data is not yet to hand). A subsequent structural interpretation of geophysical datasets has concluded that the predominantly shallow-sourced gravity and magnetic anomalies seen in EL 3429 are due to basic dyke swarms. Also, most of the surface uranium anomalies detected by the aerial radiometric coverage of the area are now though to be caused by erosion of radioactive material from the Cretaceous Bulldog Shale (6 soil samples were assayed to check this).
