An absolute age of 677 Ma +/- 12 Ma was determined from analyses of six selected zircon grains separated from the subject volcanic rock sample, but the result is strongly affected by the need to impose large corrections to the data to compensate for...

In a search for East Alligator River - type metamorphic uranium deposits, a review of previous geophysical data plus the conduct of ground and airborne radiometric surveys disclosed a number of anomalies in an area on central Eyre Peninsula extending...

Report on radiometric prospecting on EL 867 Very low uranium anomalism is associated with the Katunga Dolomite; no Middle Proterozoic overburden is located within EL 867. The anomalous alkaline syntectonic granites are of deep origin and faulting and...

Acquisition and interpretation of an airborne scintillation spectrometer survey, and the unhindered drilling and gamma and electric logging of 16 rotary open holes (total 3242 feet), were undertaken. Lower Tertiary non-marine palaeochannel sand...

Ongoing exploration for sedimentary uranium deposits and other radioactive minerals, in the plains area north-west of Lake Frome, consisted of the drilling and geophysical logging of 56 rotary holes for a total of 29,708 feet. Drillhole 355-1, which...

3 holes were drilled. Lignite was sampled and tested for wax, but this was of poor quality.

In a search for possible economic Permian coal seams buried at the southern end of the Boorthanna Trough of the Arckaringa Basin, the Petromin joint venture consortium selected an area to drill where it was inferred that such coal might lie within 300...

Airborne magnetic/radiometric surveys and follow-up gravity surveys carried out in a search for possible Olympic Dam type orebodies have indicated depths to magnetic basement in excess of 1000 m in the Lake Hart area of the Stuart Shelf. The...

In a search for economic Tertiary brown coal in the south-eastern Murray Basin, a large reconnaissance drilling programme was undertaken during February-April 1981 to test known carbonaceous sediments reported as encountered by previous drillholes and...

Drilling of two percussion holes (aggregate 400 metres) near Yerila, south of Lake Blanche, failed to give encouragement to the search for possible Permian coal and Tertiary uranium in the southern Eromanga Basin / Lake Blanche Lineament uplift area...

Fourteen stratigraphic holes were drilled in the eastern portion of the Frome Embayment in NSW.

Airborne and ground magnetic surveys were conducted in the Bundulla area of the Nullarbor Plain (SA), prior to drilling a prominent circular aeromagnetic feature. 2 percussion/rotary mud holes, each drilled to TD 369.5 m, penetrated crystalline...

Stratiform base metal sulphide deposits and sedimentary uranium accumulations were targeted in the Stuart Creek area, which straddles the Torrens Fault on the eastern margin of the Stuart Shelf. Two airborne magnetic and radiometric surveys totalling...

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...

Investigations included drilling in the eastern part of EL 41, costeaning and close space drilling near Nob Well and Apollonaris anomaly, water well sampling, and ground search for carnotite.

Targets of ongoing subsurface investigations in the plains area north-west of Lake Frome, now being conducted under a new joint venture, were respectively to delineate further sedimentary uranium occurrences within buried Middle and Late Tertiary...

As part of a continuing regional search for economic deposits of uranium and other radioactive minerals within alluvial fan sediments deposited adjacent to and east of the Mount Painter Block basement outcrops, 32 rotary holes (total 16,218 feet) were...

Marathon Petroleum's exploration investigations of EL 871 during 1982 were aimed at a detailed follow-up of prospective horizons and geochemical targets located in 1981. Rock chip assaying of selected lithologies, in particular quartz-garnet/gahnite...

Uranium mineralisation was first discovered at the old Shamrock Copper Mine during a systematic search of old mine dumps by the South Australian Department of Mines in 1955. Follow-up investigations located a small high-grade uranium lode (Valley...
