An area of sparse basement outcrop situated to the west of Lake Acraman in the central Gawler Ranges district was taken up to explore for possible economic Olympic Dam style mineralisation, based on the licensee's evaluation of past drillhole data which indicated that a number of hydrothermal alteration minerals deposited by mineralised fluids, including sericite, chlorite, haematite, fluorite and barite, which are gangue components consistent with Olympic Dam style mineralisation, had been encountered in many of the district's drillholes. Furthermore, it was recognised that a large north-west trending gravity anomaly underlies the subject licence area, which is cross-cut by north-east trending structures showing probable demagnetization. However, records research indicated that previously only a few very shallow drillholes had been completed here. A consultant's gravity data model commissioned during early 2003 downgraded the area's apparent potential for finding IOCG targets at economic depths below the surface, so attention was shifted to exploring for structurally-hosted gold. To evaluate three single-point calcrete sample gold anomalies historicaly recorded by Homestake Australia, an initial pass of reconnaissance calcrete sampling by vehicle-mounted auger drill was performed during October-November 2003 at 24 sites over gravity highs associated with interpreted buried Hiltaba Suite granite stocks and fault structure intersections, collecting 236 samples of calcrete and calcareous soil material at 500 m to 1 km sample spacing (454 m of regolith section drilled). Regolith profiles sampled in the southern half and north-eastern corner of EL 3043 consist of Pooraka Formation sands, silts and clays which characteristically sit on nodular calcrete, whereas the basement across much of the licence's northern half is covered by Moornaba Sands – vegetated dunes and sand spreads with variable carbonate content. Some difficulties occurred with the sampling, particularly in the Moornaba Sands, where some individual calcrete horizons were very thin and required composite samples to be compiled. This work returned anomalous carbonate-normalised gold values of > 5 ppb Au from five of the seventeen sites sampled, but overall the results were not as encouraging as were those obtained in the concurrent calcrete geochemical sampling programme that was conducted on Falcon's EL 2952, which lies wholly within the boundaries of EL 3043. However, it was decided that, regardless, additional calcrete sampling should be undertaken on EL 3048 , at 200 m or 100 m spacing, to try to effectively identify and define drilling targets. Further field work planned for EL 3048 was delayed over a lengthy period from 2005 to 2009 due to the licensee being obliged to wait for resolution of conflicting Aboriginal Native Title claims to the broader Lake Gairdner region, and then to seek approval for specific on-ground access to conduct a planned programme of drilling. Details of many Aboriginal heritage sites to be avoided were provided by the recognised custodians to the licensee on 3/10/2007, but when a replacement licence (EL 3996) was granted on 5/12/2007, formal permission to enter the land had to be re-sought, and a positive reply to this request was not given until 4/6/2009. In the interim waiting period, Falcon undertook further office-based target generation and refinement. Its geophysical data manipulations undertaken during 2009-2010 indicated afresh that the region covered by EL 3996 contains key geophysical attributes that may reflect a large Olympic Dam or Prominent Hill - style IOCG system, in addition to showing potential for Tunkillia type high-grade gold occurrences, as the detailed reviews of the geophysical data had disclosed several major structural intersections and coincident demagnetised zones that may reflect pervasive quartz-sericite-pyrite alteration zones possibly related to high-grade gold mineralisation. High frequency edge-detection filters were applied to the magnetic and gravity datasets to better define discrete structural targets, major lithological contacts and granite intrusive bodies. The existing calcrete geochemical data were levelled to regolith units and reprocessed to produce a series of images used for target generation. An ongoing work programme, comprising infill calcrete sampling over conceptual geochemical and gravity anomalous fault intersection targets, and the conduct of exploratory angled aircore drilling at 100 m hole spacing at Deep Well to follow up a previous downhole gold intercept made by Equinox Minerals of 6 m @ 1 g/t Au from 12 m depth in drillhole JDAC035, was planned in detail but never executed. Instead, in late January 2011 the company decided to surrender its Gawler Ranges ELs 3995 and 3996 and to concentrate its future activities, including other drilling scheduled for 2011, elsewhere within SA on its now prioritised tenements that are located in the Peake and Denison Ranges.
