Exploration for possible buried epithermal or hydrothermal gold deposits within the large variety of Archaean, Palaeoproterozoic and Mesoproterozoic basement rocks present in an area located from 20-30 km east of Tarcoola has targeted the potential of a series of prominent north-west - trending linear demagnetised zones, representing probable shear discontinuities which are aligned with known gold-bearing quartz-filled mylonite zones and quartz veins mined at the historic Company Well and Lake Labyrinth Goldfields. Early work performed by the original licensee, Jim Allender, comprised the processing and image interpretation of available aeromagnetic, radiometric and Landsat 7 satellite spectral view data, to map exposed basement rocks and regolith units, and to delineate prospective structural features. The licence was then transferred to Range River Gold, who wished to sole-fund exploratory drilling of selected gold - anomalous targets. Within the recently relinquished parts of the subject licence area, calcrete sampling undertaken by Range River Gold on a 200 m x 200m grid in April 2004 (for 132 of 366 samples) highlighted anomalous gold to 29 ppb Au in the north-westwards extension of the Lake Labyrinth shear zone. However, no geochemical anomalism was detected in these parts during a rock chip sampling campaign also conducted in March 2004 by Range River Gold (in 3 of 80 samples taken from the vicinity of old gold workings at Company Well and Lake Labyrinth prospects). During 2005, Minotaur drilled 10 aircore holes for a total penetration of 441 m to target NW-trending faults evident in the interpreted airborne magnetic data, acting on the belief that gold mineralisation occurring at the historic Lake Labyrinth mine is clearly related to faulting and shearing developed along a major NW-trending fault: concealed extensions to this fault had not been previously drill tested. However, no anomalous downhole sample assay results were returned. An isolated regional gravity high with an amplitude of ~1 mGal, coincident with a weak magnetic anomaly, was highlighted by an infill gravity survey undertaken by Minotaur in August 2005. Gravity readings were made at 2 km x 1 km station spacings, closed locally to 1 km x 1 km spacing. The resulting Bouguer anomaly and residual gravity images revealed a surrounding large regional gravity low located in the now relinquished portion of EL 3698. A subsequent detailed gravity survey was acquired in June-July 2006 to define the isolated high anomaly, by collecting data at a station spacing of 500 m x 500 m. One E-W gravity traverse and one N-S gravity traverse were also separately made across the anomaly's centre, each with a station spacing of 100 m. In-house 2D and 3D modelling of the residual 2 mGal gravity high anomaly indicate that the feature is related either to a minor increase in source density and/or to a shallowing of crystalline basement. The source body's theoretical computed SG of 2.97 g/cc means that contributing basement units are unlikely to possess significant IOCG alteration and/or mineralisation. Instead, 2D modelling of this anomaly indicates a NNW-striking body at a depth of 250 m, that is interpreted to be a mafic intrusion. The 3D model suggests that the source unit is centred at 493400mE and 6615000mN, occurs at a depth of 100 m, and is of limited depth extent. The studied gravity anomaly was deemed to be of insufficient size, extent and amplitude to allow Minotaur to infer the probable presence of significant IOCG mineralisation, and therefore further work on this area of the licence was not deemed necessary.
