A small licence area located about 50 km north-northwest of Tarcoola has been explored by Minotaur for possible IOCG style mineralisation buried under extensive aeolian sand cover, by conducting regional and infill gravity surveys over their larger adjoining EL 3040, with coverage extending in part onto the subject EL 3551. Here 81 gravity stations were read in 2005, partly on 1 km x 1 km and 500 m x 500 m grids, and also along a selected detailed, north-west trending traverse with 100 m station spacing. A significant, 10 mGal positive gravity anomaly was delineated covering 7 km x 4 km near Twin Rocks. Only the southern flank of the anomaly is present on EL 3551. This gravity feature has no associated magnetic anomaly, and has never been drilled. Depth to basement is likely to be 30 m or more. No other gravity anomalies lie within the licence.
