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...

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...

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...

Ongoing base metal exploration in the Arkaroola Station region of the north-eastern Flinders Ranges by licensee North Flinders Mines (NFM) has involved reviews of certain existing prospects, which has led to the entry of farminee Shell Minerals...

SP data acquired over the Gunsight Cu-U-Co-REE prospect has accurately located the main mineralised zone between grid 900E and 1100E, with a maximum anomaly of approximately 200 mV on line 900E. The slight asymmetry of the SP profiles confirms the...

An area 100 km north of Kingoonya which exhibits a strong regional gravity high and other, intersecting pronounced crustal geophysical features was acquired to search for an Olympic Dam type of base/precious metals deposit. Semi-detailed and detailed...

In ongoing exploration of the base metal potential of a small licence area located 34 km west of Kingscote, 5 inclined shallow diamond drillholes totalling 399 m were put down on significant anomalies located by IP surveys and/or geochemical soil...

Two inclined percussion holes were drilled at the Mount Mitchell tin prospect for a total penetration of 504 feet. The aim was to test a discrepancy between subsurface sample negative tin assay results obtained by the Department of Mines, and good...

A small area located 15 km north-east of Beltana was explored for possible economic stratabound or epigenetic/hydrothermal base metal deposits associated with Adelaidean and Cambrian calcareous/dolomitic strata and Willouran diapiric structures. Work...

A consultant's detailed regional geological study of the northern Willouran Ranges, and then his very close examination of the apparent controls on known diapir-related exposed epigenetic / stratabound copper mineralisation, have identified three...

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...

No kimberlitic indicator minerals or diamonds were detected in heavy mineral samples collected from the Jumbuck area, about 130 km south-west of Coober Pedy.

Reconnaissance and detailed bulk loam sampling undertaken to look for diamonds or kimberlite indicator minerals in the vicinity of the Pualco Anticline, plus spectrographic analyses of the derived heavy mineral concentrates for gold and base metals...

Following an airborne magnetic/radiometric survey, two rotary percussion holes totalling 819 m were drilled on negative magnetic anomalies to reach pre-Mesozoic basement (gabbro and meta-sandstone) in the Koonalda area of the Nullarbor Plain. No...

As part of a regional search for economic small-scale deposits of rare earth metals in the Mount Painter district, geochemical prospecting revealed several atypically high background niobium values, in stream sediments derived from watercourses known...

Diamond drill-hole NFK1 was drilled to a total depth of 289.56 metres at the Old Noll prospect in November - December 1972, with the aim of intersecting the buried source of mineralization that has given rise to the boxwork structures outcropping...

Surface copper carbonate mineralization occurring along a presumed shear zone was initially discovered some 4 miles southwest of the Parabarana Cu prospect by North Flinders Mines in late 1971, during a programme of detailed geochemical stream...
