An area located ~10 km west of Oodnadatta, which lies near the northern margin of the Gawler Craton, was taken up to encompass a large 240 nT magnetic anomaly with a coincident 16 mGal gravity anomaly, that it was believed had aspects analogous to the geophysical characteristics of Olympic Dam, Prominent Hill and Carrapateena. Only two holes had been drilled on the target previously, in 2002 and 2007, and in the new licencee's opinion its IOCG mineralisation potential still remained largely untested and the sources to the anomalies unexplained. No work has been done on the subject licence to date, with exploration expenditure commitments not met, and so a partial relinquishment of ground has been stipulated by DEM. The licensee decided to relinquish 292 square km or ~42% of the originally granted licence area, but is retaining the portion in the south which covers the coincident magnetic and gravity anomaly.
