Buried Archaean Mulgathing Complex rocks, comprising metamafics, ultramafics, granites, mafic gneisses and possible greenstones, were the target host for gold, copper and nickel mineralisation in the Mount Finke - Malbooma area, south-west from Tarcoola. Initial exploration for gold was by soil and rock chip sampling. Reverse circulation drilling of four holes for 280 m in an anomalous area near Pinding Rocks returned no significant results. Regional calcrete sampling at 800 m centres was undertaken throughout the licence north of the Yellabinna Regional Reserve, and gold-anomalous areas were infilled at 200 m centres. A low level detailed aeromagnetic survey over a wider area was also completed. This work defined the Boomerang prospect, which was further tested by IP and ground magnetic surveys, calcrete sampling at 50 m spacing, trial MMI assaying, and drilling of 333 aircore holes (15,466 m) and five pre-collared diamond holes (1003 m total, 729.4 m diamond core). Several holes reported gold assays >1 g/t over 2 m intervals in a varied number of basement rock types, probably corresponding to gold-bearing quartz vein intersections. Follow-up reverse circulation drilling (11 holes, 1283 m) confirmed the potential for significant gold mineralisation at Boomerang, with a best intercept of 2 m at 10.5 g/t Au from 66 m depth in hole BGRC 11. Infra-red spectral studies of cover and saprolith clay mineral samples, plus a regolith pedogenesis and geochemistry research study by CRC-LEME, were undertaken in an attempt to interpret regolith profiles and hence improve determination of the depth to basement. Further regional calcrete sampling, including a limited program in the Yellabinna Regional Reserve, did not return significant results, and a partial relinquishment was effected (see Env. 9707). Exploration continues on the reduced licence area.
