Following an airborne magnetic/radiometric survey, two rotary percussion holes totalling 819 m were drilled on negative magnetic anomalies to reach pre-Mesozoic basement (gabbro and meta-sandstone) in the Koonalda area of the Nullarbor Plain. No...

As part of a regional search for economic small-scale deposits of rare earth metals in the Mount Painter district, geochemical prospecting revealed several atypically high background niobium values, in stream sediments derived from watercourses known...

An integrated programme for diamonds combining heavy mineral and geochemical sampling, photogeology, and some geophysics has shown that EL 827's prospectivity for diamonds is extremely low. Heavy mineral sampling was negative, geochemical results...

During June-July 1972, 35 shallow vertical rotary percussion drillholes for a total penetration of 877 m were completed within the Ediacara Fault Zone to test for economic base metal mineralisation, the majority of the holes being sited at locations...

TARGET: Sedimentary uranium associated with high order radiometric anomalies over lakes on the edge of the sand dune country, east of the Nullarbor Plain. EXPLORATION: Closely spaced (300-500 m), low level (65 m altitude) aerial scintillometer...

Australian rock phosphate production has never been significant, and over the last two years steps have been taken to remedy the situation. This has and will involve time-consuming geological review work, leading to reconnaissance mapping, detailed...

Diamond drill-hole NFK1 was drilled to a total depth of 289.56 metres at the Old Noll prospect in November - December 1972, with the aim of intersecting the buried source of mineralization that has given rise to the boxwork structures outcropping...

Surface copper carbonate mineralization occurring along a presumed shear zone was initially discovered some 4 miles southwest of the Parabarana Cu prospect by North Flinders Mines in late 1971, during a programme of detailed geochemical stream...

Features interpreted from detailed low-level infill airborne coverage to a 1995 SAEI aeromagnetic survey, flown over a large area of disturbed, mainly Adelaidean sedimentary diapiric terrain located between Hawker and the south-eastern shore of Lake...

A process of rationalisation of several prior-held CRAE tenements covering Cambrian trough sediments which partly outcrop in the south-eastern Mount Lofty Ranges has led to limited ongoing exploration by that company. Ground-based follow-up of all...

Continuing intensive exploration for economic sedimentary uranium deposits within buried Tertiary palaeochannel sediments in the Yarramba Homestead area, 50 km north-west of Cockburn, which had been invigorated by the recent discovery of strongly...

During the EL 132 tenure, work has consisted of a mineability evaluation of the Honeymoon uranium deposit, plus additional U exploration over the South Eagle farmout. Initially, 5 rotary holes (total 594.9 m) were drilled to the north of the...

Stratabound, chemically precipitated Telfer - type replacement style vein gold was the target of exploration undertaken over an area 25 km north-west of Yunta, which contains good exposures of Neoproterozoic Umberatana Group clastic metasediments that...

Exploration for Broken Hill or Aggeneys type Proterozoic stratiform base metal massive sulphides within the Hutchison Group in the Mount Shannan area, north of Cleve, has included the acquisition, processing and interpretation of airborne magnetic,...

In-situ leaching of a uranium orebody can only be successful if the deposit meets a number of essential criteria. These criteria are: 1. The ore occurs in a generally porous and permeable horizontal bed underlain and overlain by impermeable strata;...

The exploration concept was based on searching for secondary uranium mineralisation that might be derived from the Musgrave Block basement rocks and that could have become precipitated within calcrete horizons from ponded uraniferous surface drainage...

Aeromagnetic, ground magnetic and EM surveys, with follow-up rock chip, stream sediment and soil sampling, RAB drilling (688 holes, total 17,553 m) and RC drilling (12 holes, total 1149 m), have defined an extensive zone of anomalous base metal...

Continuing exploration in the Woomera area has included the acquisition of a ground magnetic and gravity survey over the Buller Dam anomaly, which lies on the western flank of the Acropolis aeromagnetic anomaly, and this work confirmed that the former...

Initial exploration carried out near Lilydale Homestead, 80 kilometres south-east of Yunta, targeted possible Starra-style gold in the Braemar Ironstone facies. Flying of an airborne semi-detailed magnetic and radiometric survey identified magnetic...
