No work has been undertaken recently on the currently relinquished portion of EL 4460. However, previously this piece of ground, located between Lake Dutton and the southern end of Pernatty Lagoon, has formed part of three successive licences held either by Gunson Resources or its predecessor affiliate companies. Work done then has been reported by CSR in its annual reports submitted for ELs 1946, 2639 and 3264, and the past activity is again summarised here. In actuality, field activity on the now relinquished area occurred only during the term of EL 1946 (from 16/6/1994 to 15/6/1999). It comprised in the main a programme of shallow RC drilling performed by CSR at the abandoned Sweet Nell workings which are situated adjacent to Ironstone Lagoon (16 holes for a total penetration of 217.5 m), to test minor shows of copper mineralisation that had been mined within and beneath the sub-horizontal Woocalla Dolomite host unit. Holes SN 1 to SN 13 were completed in December 1994, and SN 14 to SN 16 in March 1995. Only narrow intervals of low-grade copper mineralisation were intersected, mostly within the Woocalla Dolomite, or in a thin black shale unit lying beneath the dolomite which is possibly equivalent to the Tindelpina Shale of the Tapley Hill Formation. The drilling verified that although minor copper mineralisation was present in the Sweet Nell area, the potential for preservation of a significant resource in this area was limited by the shallow basal contact of the Adelaidean sequence against the Pandurra Formation. This work was followed up in September 1995 by a programme of 3 diamond cored vertical holes for 32.4 m (CSND1 to CSND3) which were drilled, in conjunction with similar work on other prospects in the Mount Gunson area, to obtain geotechnical information. As it transpired, however, geotechnical logs were never recorded for these holes. Hole CSN 1 was a twin of SN 7, while CSN 2 twinned SN 15 and CSN 3 twinned SN 10. Drill logs and downhole sample analytical data for the Sweet Nell prospect are included as attachments to the subject report. The other component of field activity relevant to the now relinquished area is a subset of the pioneering (for the Stuart Shelf region) calcrete geochemisty study carried out by Stuart Metals over the Mount Gunson Project licences in the late 1990s. First-pass calcrete sampling was undertaken then, using a sample spacing of 800 m along traverses laid out 1.6 km apart. Infill calcrete sampling was later done where the first-pass assay results gave indications of anomalous base metal responses. An infill sample spacing of 400 m along 800 m spaced traverses was used by Stuart Metals in the central part of the now relinquished area, reflecting the elevated base metal response obtained in the initial sampling programme which is probably due to the shallow subcrop of Woocalla Dolomite and related Tapley Hill Formation units in the area around Lake Dutton and Ironstone Lagoon. Sample location and analytical data for all of the calcrete sampling conducted within the now relinquished area are included as an attachment to the subject report. As the calcrete sampling programme evolved, it became clear to Stuart Metals that the technique was not necessarily effective in providing a regional geochemical scan, mainly because of the poor or patchy development of a calcareous horizon with the stratigraphic units of the Stuart Shelf cover sequence. Following a review by Dr Richard Mazzucchelli, consultant geochemist, it was decided to revert to soil sampling, using a partial digest technique developed by Ultra Trace Laboratories in Perth. The analytical process used a dilute HCl partial leach, Ultra Trace code PAR 001. Specific target areas were selected, based on the calcrete sampling results and on knowledge of the presence of favourable cover sequence formations (particularly the reduced-facies Tapley Hill Formation). An extensive area surrounding Ironstone Lagoon was sampled at 200 m spacing along traverses laid out 200 m apart. While this new programme did yield anomalous results, no drilling follow-up was undertaken because the existing drillholes had confirmed the limited potential for defining a potentially viable resource in this area. The soil geochemical data for all partial-digest treated samples collected within the now relinquished area are included as an attachment to the subject report.
