An area located approximately 40 km north-west of Hawker in the southern Flinders Ranges has been explored by Copper Range as part of a regional programme being conducted in the central Adelaide Geosyncline, which is targeting large alteration zones within porous sandstone units, looking for sediment-hosted copper sulphide mineralisation. The alteration zones have been identified using ASTER satellite imagery. These zones are interpreted to be the result of basin-wide fluid flow and subsequent alteration of suitable host rocks. It was envisaged that copper-bearing fluids that had penetrated along favourable structures that cross-cut stratigraphy would have precipitated copper at reducing horizons, onto available organic material or disseminated pyrite. Initially within the subject EL, four targets were identified lying along the same horizon, in apparent association with a spectral anomaly that indicated stratabound alteration at the base of the Etina Formation, which is stratigraphically equivalent to the mineralised horizon at Kapunda to the south. These targets were known as Stardrift, Stardrift West, Nantabra and Artelevena. An additional target area was identified just to the west of Mount Neville, associated with the transition from oxidised coarse sandstones of the Proterozoic Rawnsley Quartzite (Pound Subgroup) to reducing carbonate units of the Hawker Group. This favourable stratigraphy (the old mine at Kanyaka is also at this location) forms a syncline and is associated with a significant fault that truncates the northern limb of the syncline. A notable ASTER anomaly is also present in this area. Early activities included a review of past exploration, reconnaissance visits to prospective sites, interpretation of airborne radiometric and ASTER satellite imagery, limited soil geochemical programmes at Stardrift, Stardrift West, Nantabra and Artelevena, and a more substantial soil sampling programme at Mount Neville. The soil and rock chip sampling performed over the altered reducing boundary did not shown any anomalous results at Stardrift, Stardrift West, Nantabra and Artelevena. However, at Mount Neville samples of float in creeks and of ironstone outcrop yielded anomalous copper and zinc values. The ironstone is probably related to dissolution at the base of the Wirrapowie Limestone. Soil sampling done at Mount Neville also showed anomalous results across the siltstone/limestone boundary. Follow-up soil sampling and mapping was undertaken there, with five sample lines each extending for several kilometres across the syncline. This close-spaced sampling did not identify any significant zinc or copper anomalies. Where some minor anomalies do occur, these are thought to be the result of scavenging by iron in alteration zones within the limestone. The lack of success in finding sediment-hosted copper mineralisation prompted a shift of focus in the second licence year to exploring the Cambrian carbonate rocks in the core of the syncline that previous explorers (as well as Copper Range in its Year 1 sampling programmes) had shown to be anomalous in zinc. The target now became structurally controlled Beltana-style zinc silicate (willemite) mineralisation associated with brecciation and iron-rich epigenetic solution/karst infill replacement of carbonate rocks. A geological review of the surrounding district (which includes other Copper Range tenements) was undertaken to identify suitable structural settings for hosting Beltana-style zinc silicate mineralisation, and relevant existing exploration data was compiled and assessed. It became clear that the local Cambrian limestone units has been thoroughly explored by previous explorers using stream sediment sampling, and that all anomalous zinc values which had been recorded could be traced back to ironstone development at the Parachilna Formation / Wirrapowie Limestone contact. However, the historical records revealed that Beltana was discovered from anomalous stream sediment samples carrying up to 760 ppm Zn, yet several higher values than this, of up to 1215 ppm Zn, were previously recorded in the Chace Range / Druid Range syncline (now covered by EL 3647). Nevertheless, previous explorers did not get any encouragement from field investigations made to follow up these anomalous stream sediment samples. Due to other exploration commitments, Copper Range was unable to field check any of the previous explorer’s anomalies. However, the company concluded that stream sediment sampling is probably not an effective method for detecting Beltana type targets, and that in order to continue effective exploration in the region, a previously unused technique should be implemented. It was recommended that EM be used to identify sulphide bodies and gravity to identify zinc silicate (oxide) bodies, and it was suggested that a broad scale survey would be most effective to cover all the prospective ground, i.e. an airborne EM and gravity survey. No further work ensued on the subject licence area during its final two years of tenure, apart from some consideration, with negative outcomes, of the iron ore potential of certain stratigraphic horizons within it, before a decision was made to drop the ground.
