Copper Range's review of literature relating to the modern-era mineral exploration history of the Kapunda district, which had included them studying reports written by Adelaide & Wallaroo Fertilizers that are held in private company archives, disclosed a report about a discovery of secondary copper mineralisation that had been made on the Illawarra property, located 10 km east-northeast of Kapunda township. The PIRSA geoscientific database held no record of this particular occurrence. The mineralisation had first been discovered in the early 1970s by the farm landowner, Mr W.B. Shannon, when he was ploughing a cereal paddock devoid of outcrop. The nearest known historic copper working lay 4 km due south. After encountering several float pieces of visibly malachite-stained bedrock, Mr Shannon had thereupon unsuccessfully (at first) attempted to gain interest from mineral exploration companies then working in the region, e.g. Utah Development Corp. Subsequently, local mineral processor Samin in 1973 was interested enough to dig four10-30 m long costeans in the paddock with a bulldozer, exposing some malachite mineralisation hosted by Tarcowie Formation sediments [ These costeans have only recently been in-filled by the current landowner]. During 1974 and 1975 North Broken Hill assisted Mr Shannon with making an auger drill sampling geochemical assessment of the prospect, in which he drilled ~164 shallow holes with a tractor-mounted posthole auger, and North then provided a larger drill rig to complete a further 23 holes to depths ranging from 8.5 m to 17 m, with samples taken at 2 m depth intervals. Twelve holes were designed to test for possible strike extensions to the known mineralisation, but the results were disappointing, returning values of only 65 ppm Cu or less. The remaining 11 deep drillholes were located in the costeaned area, and confirmed earlier auger sample geochemical results, with one hole (S5) returning approximately 4 m @ 4.2% Cu between 5 m and 9 m depth. However, it appeared that no more assessment work took place at Illawarra after the late 1970s, with North and other companies being unable to reach agreement with Mr Shannon about sharing in title to the mineral occurrence. As part of its subject EL 3451 exploration activities, Copper Range has undertaken 100 m x 25 m grid-based soil sampling (46 samples collected) and follow-up IP surveying over the original discovery site. The soil sampling, performed during March 2008, outlined a north-east trending > 50 ppm copper anomaly (peak value 297 ppm Cu) covering at least 300 m x 100 m, and the IP survey run in April 2008 (two 800 m long east-west traverses with readings made using a 50 m electrode spacing) defined a moderately intense chargeability anomaly. One sample of malachite-stained rock was submitted to Pontifex and Associates for petrographic analysis. Their report indicated that sample KPP-11 is a quartz-rich, medium grained sandstone with extensive interstitial malachite and with minor chrysocolla and limonite. In mid-2008 a drilling programme of four inclined RC holes totalling 500 m was proposed by Copper Range to test the Illawarra prospect. However, this work was not undertaken before a decision was recently made to include the mineralised area within the now relinquished portion of licence ground.
