Stockdale's exploration for diamonds in the Barton region, at the start of the licence period, commenced with the evaluation of 136 potential kimberlite targets generated by the detailed in-house interpretation of data acquired from an extensive new airborne magnetic/radiometric/VLF-EM survey (300 m NNE-SSW line spacing, 70 m nominal sensor height) flown over the period September 1981 to January 1982. Follow-up works, including loam sampling and later Sirotem, helicopter-borne magnetic-VLF, ground magnetic and gravity surveys, plus RC, RAB and rotary mud drilling (54 holes, total 3638 m), were undertaken up until 1987, without disclosing kimberlitic indicators or kimberlite. Subsequent precious and base metal exploration undertaken by CRA comprised an appraisal of existing data and follow-up IP and gravity surveys (Geoterrex), percussion drilling (five holes, total 605 m) and diamond drilling (one hole, 161 m), but it gave no encouraging results.
