TARGET: Possible economic, open-pit mineable stratiform low grade gold and copper deposits within Adelaidean units of the Nackara Arc, in an area lying west of and including Yunta. EXPLORATION: A detailed geological field reconnaissance, review of...

9 rock chip, mine dump, tailings, and hand auger alluvium samples were collected from abandoned gold workings. No significant assays were returned, and the area has limited potential for either bedrock or alluvial gold.

TARGET: Stratabound gold in prospective areas of Adelaidean sedimentary outcrop peripheral to the Waukaringa Goldfield. EXPLORATION: After undertaking a literature review and assessment of previous exploration results, plus a regional geophysical...

TARGET: Economic fine-grained, Telfer style gold mineralisation occurring as syngenetic stratabound deposits formed in sedimentary basins during or soon after periods of basin subsidence and instability. The eastern limb of the large, overturned...

TARGET: Stratabound gold, or hydrothermally altered vein stockwork copper-gold mineralisation that commonly is structurally emplaced within folded, brittle fractured competent Adelaidean metasedimentary units, in an area 20 km east of Peterborough....

EL 417 Wirrabara was secured by CRA to investigate previously untested aeromagnetic, induced polarisation and resistivity anomalies in the Wirrabara - Charlton area, and a reported kimberlite at Bangor. Work has consisted of: - 3 line km of IP...

As part of a regional search for possible economic stratabound Kanmantoo / Mount Torrens type base metal mineralisation, CRA undertook follow-up geochemical sampling traverses in areas surrounding Eudunda, where the SA Department of Mines and Energy...

2 main areas are outlined as likely sources, high quality marble to the N of the Penrice quarries and quartzite from many localities NW and close to Tanunda, but of lower quality.

Quaternary calcrete for surfacing gravel roads is limited. Cleaved and jointed shales and siltstones in the Tindelpina Shale Member are being exploited on the eastern limb of a syncline and test pits are recommended on the western limb. Low hills and...

Five hundred drainage geochemical samples were collected in an area of 16½ square miles over the Mount Grainger Diapir and surrounding country rock, during February and March 1963. Results of this survey outlined an extensive copper, lead, zinc...

Mapping of the Winnininnie 1:63,360 mapsheet has been undertaken as part of a programme to complete mapping of the Olary 1:250,000 Sheet. The area lies about 200 miles from Adelaide on the road and railway line to Broken Hill, and includes the...

This investigation was a feasibility study, therefore environmental factors are dealt with in much more detail than would be necessary in a routine geochemical report. Apparently these factors has little significant effect on the results. Spot...

Possible ballast sites in the area have been defined by stratigraphic and structural means. Field examination of six arenaceous units in the sequence showed that only one will provide suitable railway ballast.

A programme of stratigraphic section measurement is envisaged in order to facilitate rock correlation and help outline the pattern of sedimentation in the Adelaide Geosyncline. In many areas measurement may be made on air photo enlargement, as has...

Unworked mine reveals copper of limited extent laterally occurring as minor narrow veins and impregnations of malachite and azurite in interbedded quartzite and pebbly siltstone. Copper carbonates may have formed from sparsely dispersed sulphides in...

Includes an outline of the Adelaidean stratigraphy, and the underlying igneous and metamorphic rock types, and brief, mainly historical review of the economic geology.

Stream sediment sampling, induced polarization surveys and a 44 drill hole rotary drilling program were undertaken over the Anabama Granite. The granite was found to be unmineralized except for greisened portions containing anomalous copper and...

The main source of historical gold production at Mount Grainger has been a zone of hydrothermal wall rock alteration in the lower part of the Appila Tillite. This zone of alteration or sericitization, where a stable illite/mica mineral formed, has...
