Work done for EL 3486 during the first two years of tenure comprised reviews of existing geological and geophysical information conducted independently by Minotaur Exploration and Toro Energy. EL 3486 was partly covered by a major government-funded regional gravity survey acquired in April-May 2005 utilising a station spacing of ~2 km x 2 km. Where the survey coverage came onto the now relinquished ground, it was evident that no significant positive gravity anomalies coincide with exposed Gawler Range Volcanics and Hiltaba Suite granite. A review of existing geochemical data applicable to EL 3486 revealed a very limited dataset featuring a lack of anomalous Au, Pb, Zn or Cu values. The absence of geochemical anomalism, combined with the lack of significant gravity features, indicated that the relinquished portion of EL 3486 has less potential than the retained ground to host mineral deposit styles which the licencees are seeking, viz. Mesoproterozoic Fe-rich Cu-Au mineralisation, Fe-poor Au mineralisation, or Ag-Pb-Zn mineralisation within Palaeoproterozoic rocks. Toro Energy's regional review of geological and geophysical data determined that there is no significant potential for sedimentary uranium mineralisation on the relinquished portion of EL 3486.
