Exploration disclosed widespread uranium mineralisation, with drill-indicated reserves of 6 million tonnes, at an average grade of 0.8 kg / tonne U3O8, existing in 5 major deposits. About 625 drill holes totalling 53,000 m tested these major deposits...

Ongoing exploration for possible economic sandstone-type uranium deposits formed in Tertiary palaeochannels in the Yarramba area, 50 km north-west of Cockburn, has included further open hole rotary drilling and downhole geophysical logging (176 holes...

Exploration aimed to determine the mode of occurrence of uranium ore bodies in the Yarramba Palaeochannel, and to identify favourable drillsites. The 1980 drilling revealed significant mineralization occurring between East Kalkaroo and Honeymoon...

In first survey (reconnaissance), 6 potential palaeochannels were outlined. 2 occur in the Low Stoney prospect. The second survey was over the projected path of the Yarramba Palaeochannel north from the Honeymoon deposit, to determine its path, shape...

Basement magnetic anomaly M2 located near Sandyoota Dam on Curnamona Station, one of three anomalies mapped within EL 722 south of Lake Frome by geophysical consultant J. Ashley, was investigated for Olympic Dam style mineralization by detailed ground...

A regional survey (6130 line km; line spacing: 1 km; altitude: 90 metres) was carried out in March, 1980. The radiometric data show intense U-channel responses over an area of small salt lakes west of Lake Dey Dey. Limited ground investigations show...

The 5450 line km survey (altitude: 90 metres) was carried out from 20.2.81 to 10.3.81 and consisted of 115 lines spaced at 1 km intervals and 18 reconnaissance lines spaced at 1.5 km intervals, in groups of 5, with 11 tie lines spaced at 10 km intervals.

A study of regional geophysical data from the Stuart Shelf and CURNAMONA 1:250,000 mapsheet areas was aimed at indicating the potential for Precambrian basement uranium occurrences of Roxby Downs type within the southern Lake Frome region, since both...

No new palaeochannels were located. Pathways for the Billeroo West and Curnamona palaeochannels are postulated. The depth to basement is greatest in the north and west where a sub-basin appears to occur. Deep resistivity soundings were conducted...

Exploration of an area situated between Whyalla, Iron Knob and The Bluff overlooking Myall Creek, 20 km south-west of Port Augusta, aimed to test for Olympic Dam - type Cu-U-Au mineralisation associated with products of igneous activity located in and...

A multi-commodity mineral exploration programme carried out over an area between Mannum and Strathalbyn, seeking buried targets concealed in Tertiary sediments and basement rocks, comprised aerial magnetic, radiometric and EM surveys; groundwater,...

Following the signing of an eighteen month exploration joint venture agreement with Stockdale, farminee Mobil Energy Minerals undertook continuation of the uranium search over the anomalous ground lying east and south-east of Lake Gilles, besides...

An intensive search for possible banded iron formation - related Proterozoic stratiform lead-zinc mineralisation, of Gamsberg / Aggeneys / Broken Hill style, over an area surrounding Kimba on Eyre Peninsula, has included aerial magnetic and...

The three licences now being surrendered were originally taken out by Seltrust in the mid-1970s to search for stratabound base metals and Olympic Dam type mineralisation. After Seltrust withdrew from the subsequently formed Stuart Shelf joint venture...

Exploration for possible economic primary and secondary uranium deposits, within an area extending for 50 miles north-westwards from Cockburn and Mingary, has consisted of the first-time (for this locality) acquisition by the licence operator of an...

Following a review of existing regional geophysical and geological data for the north-western Stuart Shelf, grid-based gravity and ground magnetic surveys were run to further outline two broad gravity highs associated with discrete magnetic anomalies,...

Diamond exploration undertaken north-west of Moolawatana included the acquisition of airborne magnetic / radiometric and ground magnetic surveys, plus soil, stream sediment, gravel, loam and rock chip sampling, and aircore/diamond drilling (25 holes,...
