A number of small, disjoint parcels of available exploration ground in the Moonta-Wallaroo district were taken up by Minotaur early in 2010 to assess their basement IOCG mineralisation potential. A preliminary review done by Minotaur of historic Western Mining Corp. and North Broken Hill drilling data for the Weetulta area had shown that elevated copper, gold, nickel, cobalt and rare earth metals are present within both the basement rocks and cover sequences, suggesting that a component of supergene enrichment may have occurred since primary IOCG emplacement. During 2010, Minotaur performed a more complete review of the historical exploration and drilling data for the Weetulta area, with a specific focus on the sources identified for past IP and ground EM survey anomalism. Also completed within this period was the planning of an airborne VTEM survey on EL 4435 and the company's adjoining tenements EL 4616 (Weetulta) and EL 4541 (Anna Villa), to try to detect buried massive sulphide mineralisation. During March 2011, the said airborne VTEM survey was flown for Minotaur by Geotech Airborne Pty Ltd, with a total coverage of 501 line km. A now released subset of 60 line km of data was acquired over EL 4435. Initial post-survey processing was undertaken by the geophysical contractor, including leveling, removal of diurnal variations and noise filtering. Subsequently, the survey's complementary aeromagnetic data was gridded at quarter-line spacing and reduced to pole. The B-field channels 35 and 45 were also gridded. Interpretation of the data was undertaken by examination of the profile data for each survey line. Anomalies were selected based on their amplitude, conductivity and areal extent. Both dB/dT and B Field profiles were examined, looking for potential conductive targets. Each target was rated from “very high” through to “low” based on its geophysical characteristics. This rating work was assisted by the new, higher-quality aeromagnetic data that had been acquired simultaneously with the AEM data. Comparison of the early- and late-time AEM data provided an indication of the vertical depth extent to interpreted conductors. Numerous preliminary targets were selected. These targets were checked to see if they had cultural sources by inspecting aerial photographs, and those that were found to coincide with cultural features were discarded as probably being geologically insignificant. A field reconnaissance trip was then conducted to confirm that the remaining targets were not generated from a cultural source. Only one such target was considered to possibly reflect conductive basement lithologies. During mid-July 2011, a biogeochemical survey was conducted along 3 transects, sampling deep-rooted native Eucalyptus species (gracilus, socialis & torquata) and Black Oak (Casuarina pauper). Sampling along transects m_bio_09 and m_bio_10 was limited by the absence of appropriate vegetation species. In total, 35 samples were collected across the tenement. All gold values were below detection limits, and no significant copper values were obtained, but statistically significant anomalous zinc and silver values were detected on all three transects. As this was only a reconnaissance survey designed to gauge the viability of the methodology, its extent was limited, and no obvious correlation exists between anomalous vegetation samples and bedrock structures and degree of magnetisation. There may be a correlation with ESE-trending brittle faults, but further survey data are required to test this. No further work took place on EL 4435 during the next two years, before Minotaur decided early in 2014 to allow its tenure to lapse, without making application for renewal.
