Exploration of an area with poor basement outcrop located approximately 40 km north of Tarcoola, primarily sought possible fault or breccia-hosted mesothermal gold +/- base metal mineralisation in likely multiphase Mesoproterozoic felsic volcanic and granitoid intrusive rocks which are juxtaposed against or are cross-cut by long-lived deep crustal faults, and lie near two major regional shear zones. Initial work carried out by Aurora Gold comprised 17.7 line km of ground magnetic profiling across a prominent, 1500 nT magnitude, east-trending 6 km long x 1200 m wide regional aeromagnetic anomaly, with readings taken on 6 traverses spaced 400 m apart. In addition, 8.6 line km of gradient array IP readings were taken along 4 of the traverses. The ground magnetic data showed that this anomaly is made up of two separate highs that are bounded by conjugate fault sets, and that have the Bulgunnia Fault Zone as their eastern boundary. Next Aurora Gold conducted partial leach soil geochemical sampling over these magnetic highs, taking 34 samples at 100 m and 50 m centres to infill previous explorers' 1 km x 1 km calcrete sampling; this new sampling revealed low order copper and gold anomalism associated with a demagnetised zone centred between the highs, as well as along the southern margin of the overall magnetic anomaly. The licensee concluded that the inferred relatively shallow sources of the geophysical and geochemical anomalies were likely to be weakly mineralised ironstones interbedded within the upfaulted Palaeoproterozoic metasedimentary Hutchison Group, rathered than hydrothermally altered Gawler Range Volcanics or Hiltaba Suite intrusions. When Peninsula Minerals became the new owner of EL 2814, that company acquired a detailed gravity survey across the Bulgunnia Fault Zone southerly part of the licence during April 2004. 876 gravity stations were read at 500 m intervals along north-south lines spaced 1 km apart, with the coverage closing in further near a 1000 nT east-west aligned magnetic feature, to obtain gravity readings at 100 m intervals along lines spaced 250 m apart. This work disclosed a discrete, intense 5 mGal residual gravity anomaly that coincides with the magnetic anomaly. Peninsula Minerals considered that this dense, but as yet undrilled basement feature had good potential to host IOCG mineralisation, and sought a joint venturer to fund drilling there. After Minotaur Operations became the joint venturer of choice, and assumed operatorship on EL 2814, it carried out its own 3D computer modelling and inversions for the gravity data from Peninsula Minerals' detailed survey, which indicated that possible dense source bodies could extend from near the surface to depths exceeding 500 m, have subvertical dips, and possess a best-fit modelled density of 3.2 g/cc. To test the largest of several coincident gravity and magnetic anomalies identified just to the east of Gibraltar Outstation for its IOCG mineralisation potential, one vertical RC hole was drilled by Minotaur to a total depth of 200 m during May 2005. The basement was reached at 22 m depth, and was found to consist predominantly of medium to coarse-grained, hornblende and pyroxene-rich monzogabbro plus plagioclase-rich leucogabbro, along with minor mafic pegmatoid and porphyritic granite. Only trace amounts of pyrite and/or pyrrhotite are present. All of the rock types appeared to be massive and lacking any deformational fabrics. They also lack pervasive alteration, and do not contain any anomalous Au, Pt, Pd, Ni, Cr, Ag, Cu, Pb and Zn. The presence of abundant magnetite-bearing monzogabbro adequately accounted for the geophysical anomalies. Minotaur next conducted a regional ground gravity survey in May 2006 to cover all parts of EL 3608 that did not already have good basic gravity coverage. 284 stations were read at a spacing of 1 km x 1 km, and two positive gravity anomalies were delineated near the Bulgunnia Fault Zone. An elongate 6 mGal gravity high located south-east of Gibraltar Outstation was modelled as having a density of 3.2 g/cc. The source depth modelling gave ambiguous results, but the presence locally of minor exposures of basalt of the Gawler Range Volcanics was taken to indicate that this gravity anomaly probably reflects a buried voluminous basalt mass rather than IOCG-style mineralisation. The other, 3 mGal gravity high located east of Gibraltar Outstation was modelled as having a density of 3.0 g/cc. Its source depth modelling also producing enigmatic values. This anomaly is a westwards continuation of the main anomaly targeted by earlier drillhole TA05R005, and it was therefore postulated that a continuation westwards of the gabbroic rocks encountered by that hole would adequately account for the observed gravity anomaly. Under a prior arrangement with Minotaur Operations which gave it the rights to conduct wholly separate exploration for uranium mineralisation on Minotaur's licence acreage, newly listed company Toro Energy contracted Fugro Airborne Surveys to fly a trial airborne EM and magnetic (TEMPEST) survey over EL 3608 during August 2006. An area of 173 square km was surveyed by 453 line km of AEM profiles along flight lines spaced 400 m apart, with a sensor elevation of 120 m. The resulting processed images of the AEM late time conductor data gave good encouragement to the search for possible palaeochannel sediment - hosted uranium deposits, by clearly depicting in a depth to basement image the extent of palaeochannel features present on the licence. In mid-February 2007, Minotaur Operations and BHP Billiton decided to exit the Gibraltar joint venture. When Toro Energy formally farmed-into the subject licence in March 2007, it became the new manager, and immediately proceeded to drill and geophysically log 11 vertical aircore holes for a total penetration of 800.5 m, to try to verify the existence of the geophysically interpreted Ealbara Palaeochannel Cainozoic sediments, and to look within them for potential roll front/redox boundary sedimentary uranium mineralisation. The drilling successfully intersected a variety of palaeochannel sediments, including carbonaceous facies deposited near the channel margins. However, downhole gamma ray logging failed to detect any signficant radioactivity in these sediments (the highest log response was 133 counts per second). Drillhole cuttings samples taken at 1 metre intervals were assayed for uranium, thorium and zirconium; this yielded a maximum assay value of 32 ppm U3O8 from 61-62 m depth in hole AC07EB035. Associated elevated thorium (58 ppm Th) and zirconium (2200 ppm Zr) concentrations in the same sample interval were believed to indicate the presence of a thin band of heavy mineral sands within it, possibly containing monazite. Groundwater samples could only be obtained from two of the drillholes located 800 m apart on the same palaeochannel, which happened to be the holes that returned the highest uranium assay values. Their dissolved uranium content was found to be similar to that of seawater, i.e. 2-3 ppb, which suggested that the uranium exists entirely in its mobile phase over the area of palaeodrainage that was drilled. Toro Energy concluded that the licence area probably does not have economic uranium mineralisation within its palaeodrainage system, and recommended that tenure be surrendered. Consequently Resource and Capital Management made a formal request on 3/11/2008 to surrender the licence, after Toro Energy had withdrawn from the joint venture.
