Exploration for possible economic buried syngenetic / stratiform base metals mineralisation that may have formed in the Parndana area of Kangaroo Island consisted of the acquisition of an airborne EM/magnetic (GEOTEM) survey covering abandoned old mine prospects, for a total of 705 line km, followed by the conduct of a 30 line km ground EM (GENIE) survey and by test RAB drilling of EM anomalies (11 mainly vertical holes, total 1005 m). No major EM responses suggestive of conductive sulphide bodies were detected, and the elevated base metal values encountered in the phyllite and metasiltstone bedrock by the drillholes (highest being 2067 ppm Zn over the supergene enriched interval 6-8 m in hole 3; while the best intercepts from the interval 32-46 m within fresh bedrock in hole 2/2 averaged 300 ppm Zn) were not considered encouraging enough to warrant further exploration. Anomalous copper (487 ppm Cu) associated with weak epigenetic gold mineralisation (max. 0.33 ppm Au) was intersected by hole 8/2 located at the old Cygnet mine.
