A detailed account of the large scale copper mining and processing operations occurring in the 'Copper Triangle' region of South Australia in the few years following the end of the First World War. The included metrics and pictorial coverage of many...

An absolute age of 677 Ma +/- 12 Ma was determined from analyses of six selected zircon grains separated from the subject volcanic rock sample, but the result is strongly affected by the need to impose large corrections to the data to compensate for...

Under a joint venture agreement made between North Flinders Mines and Dampier Mining Co. (a BHP Exploration subsidiary), operative over the 7 square mile SML 705 between 14/9/1973 and 14/3/1974, at least 3500 feet of additional appraisal diamond...

As part of continuing exploration for possible economic buried stratiform / hydrothermal copper mineralisation in the Yudnamutana Mining Field, the target lower Callanna Group strata were geologically mapped, petrologically studied and geochemically...

Exploration for possible stratiform or hydrothermal, fault-associated copper deposits in the area of basal Adelaidean metasediments lying to the north of known such mineralisation at the abandoned historic Ukaparinga mine, immediately north of...

Stratiform base metal sulphide deposits and sedimentary uranium accumulations were targeted in the Stuart Creek area, which straddles the Torrens Fault on the eastern margin of the Stuart Shelf. Two airborne magnetic and radiometric surveys totalling...

Follow up to stream sediment sampling near Oodnadatta in the Mount Dutton area suggests that anomalous nickel, chromium and cobalt values are associated with ironstone, and anomalous niobium with geodes. No kimberlites were discovered.

Topics include : immediate energy crisis and uncertainty in the world energy future; world oil prices; US energy future implications for policy; conservation;oil, gas, coal, nuclear energy, solar energy and alternative energy sources; and planning for...

A computerised lineament analysis of Landsat digital image data covering the northern portion of the Flinders Ranges has shown a strong correlation between the known mineralisation and fracture structuring peripheral to granites, suggesting that...

Exploration was aimed at delineating favourable lithologies within Eromanga Basin sediments for hosting sedimentary uranium, which may have leached from the crystalline rocks of the Musgrave Ranges located to the west of the licence area. As part of...

Appraisal of a newly discovered large deposit of kaolin, found in the near surface regolith to Archaean basement on two farms situated 7 km south of Mount Hope on southern Eyre Peninsula, has consisted of further air/rotary drilling (35 holes, total...

Reports describe the ongoing field prospecting and downstream jade marketing activities associated with the Cowell nephrite jade discovery. Black nephrite blocky material extracted from the operating company's new mining leases (MLs 4130-4132) was...

In order to further test a large Delamerian granite pluton for its potential to host an economic porphyry molybdenum deposit of the Climax, Colorado type (following initial exploratory drilling and IP surveys that had been carried out by the SA...

Grid-based gravity, ground magnetic and EM depth sounding surveys were conducted in the Coondambo area in the search for Olympic Dam style mineralisation possibly associated with regional gravity highs. The licensee failed to attract a joint venturer...

Results of water bore sampling (7 samples) and drilling of 6 holes totalling 614 metres were disappointing. The drill holes intersected Adelaidean and Cretaceous sediments underlying Tertiary ? - Quaternary fluviatile sediments, without encountering...

As part of a regional diamond and kimberlite exploration programme, 50 drainage and loam samples were collected for heavy mineral analysis from within the two areas being relinquished, which lie respectively 50 km NW and 40 km NE of Kingoonya. No...

In a search for possible Proterozoic - Cainozoic unconformity - related, concealed sedimentary uranium deposits in an area of the Eucla Basin located 60 km north of Fowlers Bay, 42 rotary mud drillholes totalling 1432.4 m were put down on 5 traverses...
