The Dingo Hill tenements were applied for by Monax Mining to explore for iron oxide - associated copper-gold (IOCG) style mineralisation and epithermal style gold mineralisation associated with the Gawler Range Volcanics (GRV). The most prominent geological feature crossing EL 3394 and EL 3788 is a volcanic flow front of upper GRV lavas deposited over older, lower GRV strata. This volcanic flow front is evident in both the total magnetic intensity (TMI) and gravity data. A zone of low magnetic intensity to the north-west of the volcanic flow front is interpreted as the focus of later fluid flow and alteration of the host GRV. This zone has already been shown by Monax's early work to have minor anomalous soil geochemistry in silver, arsenic and cobalt. During December 2006 UTS Geophysics acquired an airborne magnetic and radiometric survey for Monax which covered both tenements, for a total of 4292 line km. The geophysical data were acquired along 100 m spaced east-west survey lines and 1 km spaced north-south tie lines, at a sensor flight height of 50 m. The new detailed magnetic data greatly improved the resolution of the magnetic features within the survey area, and when combined with gravity data from the 1 km x 1 km gravity survey conducted earlier over EL 3394 by Monax, more accurately delineated the northeast-southwest trending volcanic flow front that forms the lateral boundary between interpreted upper and lower GRV. The data also highlighted north-west trending fault structures which were believed to be key zones for hydrothermal fluid flow, and thus constituted preferred drilling targets. The weakly anomalous polymetallic geochemistry reported from the soil sampling done on EL 3394 early in 2006 (see Env 11300) was considered to be encouraging, because it coincides with the zone of most intense demagnetisation within the central region interpreted alteration zone. This particular area is covered by palaeodrainage alluvium, and so the elevated metal values might represent a subtle surface expression of underlying epithermal gold/base metal mineralisation. At the end of 2007, Monax submitted to PIRSA a proposal for a Round 5 PACE collaborative drilling project comprising three to four RC/diamond holes, each to be drilled to total depths around 400 m. The aim of the drilling project was to test the Dingo Hill demagnetised zone and coincident soil geochemical anomaly. This PACE proposal was accepted in February 2008 as Project DPY5-11. However, the planned drilling programme was not undertaken within the required timeframe due to unavailablity of drilling rigs. Subsequent events then dictated that the drilling work could not be started owing to Monax's priority exploration commitments on other licences, and so the PACE assistance opportunity was forfeited. Instead, Monax continued with its office-based review of available geological and geophysical information, in order to refine the mineralisation model and select optimum future drilling targets. During November 2008 Monax geologists carried out a brief field trip to map some bleached outcrops that had been photointerpreted from Google Earth, and also to sample the regional quartz vein sets. 8 rock chip samples were collected and analysed, but only one sample showed anomalous Ag,Cu, Mo, Pb and Zn. It had been taken from a quartz vein carrying weathered remnants of sulphide (probably pyrite). No further work was undertaken on the subject tenements, after management decided that the identified anomalies held no significance as IOCG targets, and the effects of the global financial crisis took hold on planned expenditure. Eventually the decision was made to surrender tenure.
