An area located approximately 40 km north-northwest of Kimba is being explored primarily for possible buried basement-hosted Olympic Dam style iron oxide - associated copper-gold(-uranium) deposits, as well as for fault-related vein style uranium deposits and roll front type uranium deposits. Exploration work conducted by Southern Uranium within the now relinquished portion of the licence has consisted of a regional gravity survey, an infill gravity survey, regional soil sampling, and the completion of one diamond drillhole to a depth of 952 m. 167 new gravity stations were read at 1 km x 1 km spacing across this area during September 2006, and infill of 210 stations read at 250 x 250 m spacing was acquired during January 2008. A geophysical consultant's modelling of this gravity data indicated an anomalous weakly magnetic but dense source body at an inferred depth of 400-500 m, corresponding to a 2.5 mGal, 2 km x 1 km residual gravity anomaly located in the vicinity of Waxings Dam. Outcrop near Waxings Dam consists entirely of Proterozoic quartzite, and previous drilling carried out to the south-west had logged sericite alteration in this rock at shallow depths of about 20 m. The target body was thought to be an iron oxide - altered Proterozoic Hiltaba Suite granite intrusion (outlier of the Cunyarie Granite batholith) emplaced along a regional north-east trending basement fracture zone. However, diamond drilling of this target during March-April 2008 with hole WD DDH-01 (RC precollared to 214 m depth) failed to find any indication of lithologies, alteration or mineralisation associated with IOCGU style mineralisation, nor vectors to any other known style. The drillhole encountered a garnet-rich quartz-feldspar gneiss to migmatite containing abundant pegmatite zones, indicating high temperatures. A later dolerite dyke (possible Gairdner Swarm dyke) appears to have intruded along a pre-existing fault, as there is a distinct change in the metamorphic grade from one side of the dyke to the other. Minor coarse, blebby pyrrhotite and pyrite were observed, and sporadic traces of chalcopyrite as inclusions within the other sulphides. Assaying of 163 downhole core chips taken at 4 m depth intervals did not return any significant trace metal or rare earth element values. Partial leach soil geochemical sampling undertaken across the relinquished ground (225 samples collected at 1 km spacing early in 2009) detected several very subtle Cu-Au anomalies, which could have been followed-up with 500 m spaced infill soil sampling; however, the TL8 alkaline partial leach assaying results had failed to highlight the known Wirrigenda Dam Zn-Pb-Ag prospect within the soil survey grid, and thus the usefulness of the chosen analytical method targeting regolith enrichment processes was questioned for this area. Of note is the very shallow depth of cover at the WD DDH-01 location, with only 1 m of sand and calcrete overlying highly weathered garnet gneiss. Because the soil geochemistry results are not considered significant enough to warrant further work (i.e. drilling), and because Investigator Resources at present has a number of other prospects of higher priority located elsewhere on the extensive project acreage, it was decided to relinquish the subject part of EL 3594.
