To evaluate potash potential, brine samples were collected from below the dry bed of Lake Cadibarrawirracanna, and analysed for Ca, Mg, Na, K, B, HCO3, C1, total phosphate and sulphate. Potassium contents were too low to be of interest.

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...

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...

Uranium mineralisation was first discovered at the old Shamrock Copper Mine during a systematic search of old mine dumps by the South Australian Department of Mines in 1955. Follow-up investigations located a small high-grade uranium lode (Valley...

Outcropping Wywyana Formation in the Mount McDonnell Valley, which had been shown by past work to be highly anomalous in copper, with attendant gold enrichment, was targetted by 50 m by 20 m grid-based geological, geochemical and ground geophysical...

Previous geophysical interpretation reports of regional geophysical data for the Mount Painter Province have been reviewed, and any available source data has been examined afresh to try to generate additional exploration targets. Unfortunately, many...

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...

An area of 100 square km, located 45 km west of Kingscote, was taken to enable follow-up exploration of some anomalous stream sediment geochemical sample values in lead (to a maximum 3200 ppm Pb) previously discovered by Elcor (Australia) Pty Ltd, but...

Ongoing exploration for possible Tertiary sediment-hosted roll front uranium occurrences in an area abutting western Lake Frome has consisted of the drilling of 7 open rotary holes for a total of 1384 m, to test ground midway between previously...

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...

14 rotary percussion holes were drilled to test for extensions of the Klein Point limestone deposit. In the area drilled, Tertiary bryozoan limestone horizons were found to have an average vertical thickness of 28 m; their quality is comparable to...

Late in 1981, BHP Minerals whilst exploring on its Orroroo region EL 891 discovered four stream gravel samples containing kimberlite indicator minerals. The stream drainage system in which these samples occur commences south of the southern boundary...

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...

As a part of continuing exploration for possible economic buried epithermal / hydrothermal / metasomatic and skarn-related base metal and gold deposits undertaken within an area of shallow Lower Proterozoic basement located approximately 30 miles west...

In a search for possible concealed Olympic Dam type base metal deposits within an area located 80 km north-west of Yalata, the licensee investigated several previously identified contiguous magnetic and gravity anomalies by performing ground magnetic...

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...

Drilling of 3 rotary mud holes totalling 392 m on gravity lows in the Mabel Creek area disclosed only thin seams of lignite at about 66 m depth. Because the holes were not geophysically logged, the coal seam thickness could not be ascertained....

Detailed stream sediment, loam and barrage sampling carried out over the main channel and various tributaries of the Manunda Creek drainage system confirmed the presence of widespread kimberlitic indicator minerals, plus a 31 microdiamonds. 5 small...
