Zinc silicate (willemite) mineralisation occurs in a host rock of Lower Cambrian Ajax Limestone, which represents part of a sequence of Proterozoic to Middle Cambrian sediments that rests unconformably on folded lower Adelaidean Willouran siltstones...

A number of base metal occurrences in the northern Flinders Ranges, previously classified as syngenetic, diagenetic and epigenetic in nature, appear to have resulted from metalliferous brine-sediment interaction with autochthonous and allochthonous...

Outcrops in the banks of the Onkaparinga River at Old Noarlunga, and in coastal cliffs near Ochre Point between Moana and Maslin Bay, South Australia, provide a record of late Neoproterozoic, (including early Ediacaran) and Cenozoic sedimentation and...

The reports comprising this data release package describe exploration for economic deposits of base and precious metals that have possibly formed within Neoproterozoic metasediments, the underlying Palaeoproterozoic basement, and in Cambrian carbonate...

Exploration of the area around the margins of the Oraparinna Diapir for commercial barite deposits has consisted of aerial photographic studies, plus ground geological traverses of photo-interpreted fault structures, and geological mapping, trenching...

An area located approximately 57 km east of Beltana was taken up to explore for possible economic hydrothermal/stratabound, replacement-type base and precious metal deposits in Neoproterozoic Callanna Group diapiric breccias and rafted dolomitic...

As part of a regional stratiform base metals exploration programme, the conduct of a helicopter-assisted stream sediment geochemical sampling survey (506 samples assayed) did not reveal any anomalies of interest.

Exploration undertaken in an area of practically no outcrop that is situated north and north-west of the Ediacara Range, on the eastern side of Lake Torrens, has aimed primarily at investigating the mineral potential of a large, low amplitude...

Two vertical rotary percussion drillholes totalling 490 feet were put down on a zinc-rich gossan at the Patawarta prospect, which had been discovered through soil sampling of the Late Proterozoic Bunyeroo Formation calcareous siltstone subcrop...

Cultana is located on parts of the north-eastern Eyre Peninsula, northern Spencer Gulf and south-western Flinders Ranges, and is underlain by rocks of the Mesoarchaean-Mesoproterozoic Gawler Craton, the Neoproterozoic Adelaide Geosyncline, Torrens...

Previously detected low-level geochemical anomalies for Cu, Pb and Zn were confirmed by follow-up stream sediment and soil sampling. Field inspections were made by helicopter of selected anomalous areas in the Upper Proterozoic and Lower Cambrian...

South Australia's famous desert opalfields supply about 80% of the world output of precious opal, with current production coming almost entirely from the major fields at Andamooka, Coober Pedy and Mintabie, each of which is expected to increase output...

Exploration for diamonds, undertaken in an area centred 60 km east-northeast of Lyndhurst which had not been searched for this commodity previously, comprised the acquisition of aeromagnetic/radiometric and helimag surveys, and gravel and loam...

Adelaidean and Cambrian calcareous clastic rocks of the Angepena region were investigated for possible economic epigenetic base and precious metal mineralisation that may be related to syn-depositional faulting, as well as for stratiform and...

3414 geochemical reconnaissance stream sediment samples were taken over an area of 277 square miles for NFM during the period December 1969 - August 1971, and analysed for anomalous Cu/Pb/Zn in Sturtian-Marinoan to Lower Cambrian bedrock...

Exploration of a small area of Neoproterozoic and Cambrian fold belt strata in the Jubilee Hill - Mount Roebuck area, located 45 km east-northeast of Blinman, was aimed at finding possible economic base and precious metal mineralisation associated...

Reconnaissance stream sediment geochemical sampling (258 samples) and a detailed geological inspection of resultant base metal anomalies, plus follow-up rock chip and stream sediment sampling, have outlined several minor base metal geochemical...
