Oz Minerals shares light up on South Australian copper find OZ Minerals shares are more than 10 per cent higher after the company announced good copper exploration results near its Carrapateena project. The company said it had intersected 34m of 1.61 per cent copper from 613m and 108m of 0.92 per cent copper from 1033m. The stock was up 44c at $4.44 in early trade. The Khamsin prospect is about 10km north-west of the Carrapateena project in far north South Australia, which is currently the subject of a pre-feasibility study. "It is very encouraging that within four holes of discovering mineralisation at Khamsin we are starting to identify higher grade zones that appear similar to those we see in the main body at Carrapateena," Oz managing director Terry Burgess said. We will now follow up this drilling to begin to ascertain its scale and significance in the broader Carrapateena project. This most recent drilling is encouraging as, for the first time, the copper grades and intervals of bornite and chalcopyrite (both copper minerals) are of similar tenor to those seen at Carrapateena. The sulphide mineralisation is best described as containing strong intervals of disseminated and fracture infilled bornite interspersed with fine to medium grained veined and blebby disseminations of chalcopyrite. Results from the last 350m of the hole are still awaited, however, the strongest visual mineralisation observed was within the intersections reported above.
