TARGET: Epithermal and unconformity - type uranium in Archaean to Early Proterozoic rocks of the southern Gawler Craton. EXPLORATION: - an aerial magnetic and radioactivity survey flown at 800 m, 1600 m and 400m spacing by Austirex in November 1979; - reconnaissance geological mapping, rock chip sampling and radioactivity surveys of outcropping basement rock types that include augen and hornblende-biotite gneisses, amphibolitic metasediments, marbles, graphitic schists and lower grade pelitic and phyllitic rocks; - geochemical and petrographic studies of various rock units; - bedrock sampling by auger drilling (121 holes totalling 2014 m); - 8 (including 1 stratigraphic) diamond drill holes (total 1167.5 m); and - follow-up of radiometric anomalies by ground magnetic and radioactivity surveys, soil sampling, trenching, geological mapping, and RAB plus limited core drilling (153 holes, total 4013.5 m). RESULTS: The exploration model was fully tested over the entire licence area, but no uranium occurrences were found that corresponded to a number of radiometric values above background, which seem to be caused more by elevated thorium and rare earths associated with late, minor intrusive plutonism.
