A reassessment of Marathon Petroleum's 1979 regional stream sediment sampling programme led to the decision to resample a number of areas within EL 871. The Mt Neill and Mt Fitton areas were chosen, as a result of possible similarities with the...

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...

During the current licence term Aquitaine conducted ongoing evaluation of its recent placer scheelite mineral discovery near Keyneton, south-east of the Barossa Ranges. Additional field reconnaissance, rock chip sampling and petrological study, much...

The target in the Kanmantoo mine area was Cambrian stratabound lead-zinc mineralisation known to be associated with pyritic units of the Brukunga Formation, and copper associated with andalusite-staurolite-garnet-chlorite-biotite schists in the same...

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,...

Geological surveys and sampling reveal that sporadic skarn outcrops which extend over a strike length of some 2500 feet, and widths of two to twenty feet, have an average grade of 0.10% WO3. There are extensive soil covered areas which may overlie...

Investigations have shown that in the Sir Joseph Banks Group, molybdenite and scheelite are confined to the southern tip of Spilsby Island. The minerals occur in thin irregular veins, in masses of quartz, and as disseminations scattered through...

Known occurrences of fluorite have been examined for a source of low grade fluorite - quartz ore for chemical manufacture at Port Adelaide. No suitable deposits were found. Further enquiries of a possible source from the Broken Hill Lodes is suggested.

Rocks in the Flinders and Hutchinson groups are exposed sporadically around the coast of Eyre Peninsula. Reported occurrences of molybdenite and scheelite in these rock types were investigated. No significant rare metal minerals were found in the...

In the Sir Joseph Banks Group of southern Spencer Gulf offshore islands, outcropping Archaean arenaceous, arkosic and calcareous sedimentary rocks appear to have been folded and granitised prior to the deposition of the Adelaidean System sedimentary...

A request was made to the director of Mines by Mr. F.J. Ashmead for a geologist to inspect his registered scheelite claim No. 1990 located near the landmark, "Woman in White". This assistance he believed would help to guide his exploration work. A...

In a regional soil sampling survey over Willyama Complex rocks on parts of the Outalpa 1:50 000 Sheet, 2443 samples were collected at 25 metres intervals on 54 lines roughly 1km apart. These samples were analysed for CU, PB, Zn, Au, Mn, Mo, Co, Ni, V,...

History from 1884 when silver, lead and copper were discovered in the Rapid Bay area.

About 1,500 samples were collected during a stream sediment sampling survey on the Riverton and Eudunda 1:63 360 geological sheets and analysed for Cu, Pb, Zn, Au, W, Mo, Nb, Co and Mn. Rolling means, residual values, correlation coefficients and mean...

Volcanism associated with the Middle Proterozoic Gawler Range acid volcano-plutonic province was initiated in the Kokatha area by the construction on Archaean basement of a large stratovolcano composed mainly of tholeiitic basalt and potassic basaltic...
