An area located approximately 80 km north-east of Streaky Bay was taken up to explore for possible Hiltaba Suite intrusion-related, structurally controlled gold mineralisation formed at the southern end of the Yarlbrinda Shear Zone (YSZ) , in a similar geological setting to the recently discovered Tunkillia gold deposit located ~100 km to the north. The surrounding central Gawler Craton of South Australia is emerging as a major new gold province following the discovery of the Tunkillia deposit and the identification of other significant prospects which may develop into economic deposits. Adelaide Resources have identified numerous areas of calcrete and bedrock gold mineralisation on their northern Eyre Peninsula tenements, the most significant to date being the Barns prospect. Locally, a number of geochemical gold anomalies identified by previous explorers' surface calcrete sampling and limited bedrock drilling remained unexplained, and thus were considered worthy of follow-up, while a 16 km long section of the YSZ within the new tenement area appeared to be completely untested, and contains a demagnetised zone near its centre that could reflect hydrothermal alteration of the underlying rocks. A major northwest - trending zone of complex inferred post-Hiltaba faulting intersects the YSZ within the tenement boundaries. It was thought that the presence of only a thin mantle of Gawler Range Volcanics, plus the relatively shallow transported sedimentary cover aggregating just a few tens of metres, would offer a better exploration environment than the Stuart Shelf to cheaply apply new concepts and techniques towards discovering new gold deposits. After performing a regional geophysical and remote sensing data interpretation, the licensees initially undertook soil sampling and radiometric scans of lacustrine sediments in an area of salt lakes occupying the southern part of the licence, to follow up two airborne radiometric uranium channel anomalies related to these lakes. 209 soil samples were collected along 3 traverses spaced 100 m apart, scanned with a hand-held scintillometer, and submitted for multielement analysis. Spotty elevated values of up to 28.5 ppm U and 6 ppb Au were returned. Shortly after this, calcrete geochemical sampling was carried out along swales in the dune -covered northern part of the licence during December 2005 (108 samples collected on a nominal 500 m x 1 km spacing). Assay values were generally low, with the best gold return being 2.6 ppb Au. During December 2005 - January 2006 detailed and semi-detailed gravity surveys were acquired over two regional gravity anomalous areas which it was thought might have IOCG mineralisation potential. 275 stations were read on 200 m x 800 m grid spacings across two selected anomalies, and a single traverse of a further 238 stations was read along a track passing through the centre of the tenement. To assess the licence's prospectivity for finding possible Tertiary sedimentary roll-front style uranium deposits of the type identified by Carpentaria Exploration in the region during the late 1980s, Southern Gold flew an airborne Hoist-EM survey of 240 line km across the inferred subcrop of the upper Yarrana Palaeochannel during January 2006. The interpreted EM profile conductivity anomalies were then aircore drilled during November-December 2008 (26 vertical holes for a total penetration of 2507 m). This work produced disappointing results when it revealed only a broad, thinly developed upstream palaeochannel setting, having uniformly reduced and mainly fine-grained Eocene fluvial sediments that contained only very low amounts of uranium and other trace metals (e.g. a peak assay of 8 m @ 21.9 ppm U from reduced silt and lesser clay at 60 m depth in hole YSAC023). No anomalous radioactivity was detected by scintillometric scans of the drill cuttings, and no visible indications of economic base and precious metals, or of heavy mineral sands, were encountered within the drilled sequence sampled down into the top of basement. It was surmised that the uranium values detected geochemically might be coming from acidic reagent digestion of monazite grains from heavy mineral sands laminae within the Eocene sediments, since these values are associated with elevated thorium, zirconium and titanium. Although the results of the aircore drilling programme at first seemed to be uninspiring, it was realised that the drilling had been restricted to easily accessible areas (i.e. existing tracks) due to environmental considerations, rather than selecting a range of targets across the tenement. Consequently the Narlaby Palaeochannel portion on EL 3160 had really only been tested in one broad traverse, meaning that there could still be potential for redox-style uranium to occur further 'upstream' (to the east). The highly reduced nature of the sediments already intersected in the palaeochannel (shown by the presence of abundant pyrite) showed that the drilling done to date was perhaps too far 'downstream', and that plenty of scope should exist for finding redox-fronts elsewhere on the tenement.
