As part of a regional search being made predominantly for possible Archaean to Mesoproterozoic basement - hosted buried IOCG or mesothermal gold deposits, exploration carried out within an area centred approximately 35 km west of Tarcoola has comprised the following work programmes undertaken by joint venture partners: - A regional gravity survey was conducted by Haines Surveys for Minotaur Exploration during September-October 2005, when a total of 1661 gravity stations were read, incorporating regional data acquisition at a 1 km x 1 km spacing, plus infill coverage acquired at 500 m x 500 m spacing. This survey was conducted in order to identify potential IOCG targets which are typically associated with large gravity anomalies. It disclosed a large anomaly, approximately 3.5 km x 5 km in size, which is open to the east, though the peak of the anomaly appears to lie within EL 3040. This 10 mGal amplitude gravity anomaly is not associated with any significant magnetic response. 3D modelling of the gravity data indicated a probable source body average SG of 3.1 g/cc and a maximum depth to target of ~400 m. In addition, sections of another detailed gravity survey (collected in 2005, but only processed and interpreted in 2006) fall within the 2009 and 2010 partial relinquishment areas of ground. This detailed work had targeted Tertiary palaeochannels of the Warrior prospect, and passed directly over the 10 mGal anomaly. Gravity readings had been made by Haines Surveys along north–south and east–west lines at 25 m and 50 m station intervals. Data from the N-S lines were subsequently used in the 2D modelling, the added precision suggesting a better fit SG of 2.95 g/cc and a revised depth to target of ~250 m. - During August 2006, Fugro was commissioned to undertake low level (120 m flight elevation), 400 m line spaced TEMPEST AEM data capture for Toro Energy. The aim of this survey was to verify whether airborne EM data obtained by the TEMPEST method was suitable for mapping subsurface conductivity discontinuities within the region, and to see if the processed EM data could provide high quality information on the alignment and location of the targeted palaeochannel. The survey flight lines were orientated east – west to cover the dominantly north-south running palaeochannel. Sections of this AEM survey were flown within the now relinquished licence subareas, and the relevant processed data is now being released in the form of stacked output profiles and a contoured depth to basement image. On this image the contoured AEM data has been colour enhanced to delineate a potential palaeochannel drainage system. - During 2007 Minotaur reprocessed Toro’s TEMPEST AEM data and identified a number of EM anomalies within the survey Area 2 data subset, including two significant anomalies lying within the now relinquished ground which were prioritized for later follow-up with field investigations of the outcrop geology, possibly supplemented by outcrop geochemical sampling, and with ground EM profiling to confirm the targets. - During February and March 2008, 5 aircore drillholes with a total penetration of 400 m were completed on EL 3040 within the now relinquished portions of this licence. The aim of the drilling was to “sterilise” outlying historical anomalies with a view to clearing the way for tenement reduction. Gamma ray logging was carried out at completion of each hole, using an Auslog wireline logging tool deployed within the drillstem. Four of the drillholes were positioned near the northern edge of the licence in order to test the Mulgathing Trough for uranium mineralisation. Selected drill cuttings samples were taken at 1 m intervals over logged zones of high gamma radiation and sent for XRF assaying of uranium, thorium and zirconium content. No evidence of significant mineralisation was encountered in any of the drillholes, and the downhole sample assay values were of a low order.
