Part of the Cleve Uplands centred 15 km west of Cleve has been taken under licence to explore its potential for buried economic copper-gold mineralisation to occur within Archaean or Proterozoic basement rocks. Other possible commodities of interest are primary base metals and uranium, and gypsum within the cover sequence. During the first licence year, operator Redfire Resources reprocessed and interpreted available aeromagnetic data, which highlighted the likely presence of prospective Middleback Jaspilite in the eastern part of the tenement area. Regional soil calcrete geochemical sampling was started, with 43 samples collected for assay at ~4 km grid centres, and returned some gold anomalies of interest. An occurrence of high grade seed gypsum containing up to 93% CaSO4.2H2O was identified in an existing pit located 5 km east of Konanda. During licence Year 2, the farm-in agreement made between grant licensee Olliver Geological Services and Redfire Resources was terminated on 31/7/1998. The licensee continued to explore for gypsum and granite dimension stone. An aerial survey of visible surface landform features was made on 31/5/1998 over the region extending from Caralue in the north to Arno Bay in the south, and many potential gypsum deposits in the form of salt lakes and associated lunette dunes were observed, as were several outcrops of granite. Follow-up sampling was conducted of the gypsum composition within lakebed sediments in two of the salt lakes located near Arno Bay, and for comparative purposes of production stockpiles lying adjacent to the Taragora gypsum deposit on ML 5974 (6 samples assayed). Both the Lakes View and Werrina occurrences were found to contain premium grade (>90%) gypsum on a salt-free basis. The Werrina prospect dune on the south-eastern side of that salt lake was estimated to contain ~20,000 t of in situ gypsum resource. During licence Year 3, over the period May to August 1999, new farminee Adelaide Resources began to do regional reconnaissance soil calcrete geochemical sampling across the entire licence area at 1.6 km centres, looking for copper-gold and base metal dispersion pathfinders. 390 samples were collected and laboratory assayed, and a number of anomalies of interest were disclosed which warranted investigation by infill sampling. The execution of this work according to the farm-in agreement served to earn Adelaide Resources a 90% interest in EL 2305. A second partial relinquishment of 394 square km or ~45.7% of the original area of EL 2305 was made on 4/4/2000. No calcrete geochemical anomalies had been detected on the relinquished ground portions. During licence Years 4 and 5, no work was done by either partner in the joint venture. Adelaide Resources continued to seek an additional joint venture partner to assist it with progressing the gold and base metals search on a number of licences which it held across the Eyre Peninsula, but no such partner was attracted.
