The Kartanya iron ore prospect is located in the central Eyre Peninsula region, approximately 100 km west of Cowell and about the same distance north of Port Lincoln. Haematite mineralisation was discovered in the area by Western Mining Corp. while exploring EL 1884 in 1992 for base metals. Rio Tinto Exploration were granted EL 2066 in March 1995, for the purpose of finding possible mineable iron ore deposits along strike from WMC's discovery drillholes. In January 1998 Hammersley Iron's Resources Task Force were asked to examine additional geoscientific data acquired by Rio Tinto for the Kartanya prospect, with a view to defining the iron ore resources (haematite/magnetite) potential, and as a result giving Rio Tinto advice of any commercial interest that Hammersley Iron might have in producing those resources. The findings of the present study are: - the iron ore resources at Kartanya are low in iron and high in deleterious components such as phosphorous, carbonates, manganese, alkalis, sulphur, etc. However, there exist some narrow high grade intersections low in impurities which provide stimulus for ongoing exploration for better quality deposits nearby. - the prospect has an estimated Inferred category resource for high phosphorous (> 0.1%) haematite of 8 Mt at an average grade of 59.8% Fe, 5.2% SiO2, 2.08% Al2O3, 1.32% CaO + MgO, and 0.10% TiO2. An additional resource of 2 Mt could be expected from ore zones interpreted on cross sections beyond drilling. - the resource is too small in size, poor in quality and distant from the nearest port to be economical for exploitation presently, and the ore makeup is unsuitable to provide direct shipping ore in its present state; however, scope for product upgrading after processing is quite high. - the tenement contains several anomalies over 2 km long that have > 50 000 nT magnetic susceptibility, are distributed along a 15 km strike length, and lie to the east of the present drilling. These may correspond to buried magnetite deposits (high and low grade) which, after beneficiation, could provide suitable pellet or DRI feed. - the tenement has the right address, so the chances of finding other large, high grade magnetite/haematite deposits cannot be ruled out. - there is no metallurgical information on the ores. A short drill programme of 5 holes is suggested to test the resource for these characteristics, and to provide further data on its lithological and chemical aspects which are lacking at present.
