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...

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...

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...

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...

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...

This report summarises the relevant results of previous copper exploration in the Yudnamutana Hill area by Utah Exploration Co. and Australian Aquitaine Petroleum Pty Ltd, and suggests an ongoing exploration programme for stratiform copper. It also...

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...

Thirty-two shallow auger holes up to 2.76 m deep were drilled into the floor of Lake Cadibarrawirracanna, situated 70 km west of William Creek, in a search for possible potash-rich brines trapped by the lake sediments. The lacustrine sediments were...

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...

An extensive exploration programme for lead-zinc mineralisation of Mississippi Valley style, targeting a horizon lying within Lower Cambrian carbonate metasedimentary units, was undertaken over an area located 35 km north of Hawker. Initial...

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...

Detailed follow-up to earlier regional stream sediment sampling, which had disclosed several robust kimberlitic garnet indicator anomalies in relatively featureless terrain, was successful in discovering three outcropping thin kimberlite sills in the...

In a search for possible economic primary or secondary uranium deposits in the Rudall area, five streambed mud samples and 2 springwater samples from the Driver River drainage basin were analysed for Central Pacific Minerals by the Australian Atomic...

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...

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...

Exploration of an area located approximately 10 miles north of Manna Hill, seeking possible economic Zambian Copperbelt style stratabound copper deposits, has consisted only of an orientation geochemical survey followed by field inspection of...

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...
