An area centred ~20 km north of the Challenger gold mine has been explored for possible buried primary Challenger type basement gold lodes and also for secondary roll-front style uranium mineralisation that may be hosted in buried Tertiary fluvial sediments of the Garford Palaeochannel. During licence year 1, no field work was done. A consultant geologist was engaged to do a desktop prospectivity review of the area's Archaean basement and Tertiary cover sequence. During licence year 2, further evaluation of surface (calcrete) geochemistry, drilling and geophysical data led to a decision that more work appeared to be warranted at Southern Gold's Nemesis prospect located in the southern part of EL 4971, as it was thought that possible occurrences of Challenger-style narrow high-grade gold shoots could well fit between the traverse spacing of the historic (2010) RAB drillholes. Therefore it was recommended that additional RC drilling be performed to test across the trend of the anomaly, using inclined fenced holes. During licence Year 3, UXA undertook a detailed office-based review of the past Nemesis prospect drilling and the mineralogical logs and assay results of the drill cuttings samples, besides conducting a detailed review of the previous company's bulk leach soil sampling data. The conclusion was reached that a mineralised retrograde shear zone, possibly up to 100 m wide, could be present at Nemesis. Interpretation of the previous regional soil sampling results also suggested that this zone might be up to 1.5 km long. UXA considered that the work already completed on Nemesis should be mimicked in any future exploration orientation approach to covered parts of the licence area not yet explored. Plans were made to extend the existing calcrete and soil sampling grid to parts of the tenement located outside of the interpreted palaeochannel subcrop positions. [No 6-monthly summary or annual reports were submitted to DSD for licence Years 4 and 5, as is required under the Mining Act, and no application was made to renew the licence for a second term, so consequently the tenure of this ground by UXA has now lapsed. The former licensee is being fined by DPC to penalise the company for not meeting its basic exploration reporting obligations].

Notes: UXA Resources Limited (UXA) was placed into voluntary administration on 26/7/2013, and was suspended from trading on the ASX. During December 2013, UXA's Administrator made a Deed of Company Arrangement with private exploration group Palgrave Resources Ltd. The management and finances of UXA were restructured, with the intent that the company would shortly be relisted and recapitalised. On 5/5/2015, UXA exited administration and was no longer subject to the Deed of Company Arrangement.
