Scout drilling of gravity low anomalies in the western half of the buried Permian Wallira Trough (2 rotary mud holes totalling 100 m), in a search for possible economic Upper Permian coal seams which might extend westward from those discovered in the Lake Phillipson region, failed to find coal, and encountered Pre-Palaeozoic basement at shallow depth (approx. 40 m). Neither drillhole was geophysically logged. Ground-based geological reconnaissance, and scintillometric total count logging of all drill cuttings, were also performed, but no mineralised outcrops or downhole sediment radiometric anomalies of significance were noted. Assaying of selected drillhole samples for possible sedimentary gold or uranium yielded disappointing results.
