Age demonstrated by stratigraphic relationships with palynologically dated sequences, and evidence of erosion of silcretes.

Detailed mapping undertaken between 1982 and 1987 of 48 known jade outcrops located in the Cowell - Cleve area, and diamond drilling of 3 jade outcrops and 2 ornamental marble prospects, has identified many factors controlling nephrite formation. The...

The Challenger gold deposit lies in the northern Gawler Craton, South Australia, 750 km NW of Adelaide, and 140 km NW of Tarcoola. A 1.5 km traverse (the regolith line) was chosen for the study of geochemical dispersion and regolith stratigraphy...

The Poona Copper Mine on northern Yorke Peninsula, South Australia, was worked from 1988-92 on an extension of the original Poona lode, a narrow, shear-hosted copper sulphide vein deposit in Moonta Porphyry of Mesoproterozoic age. The orebody is...

Twenty-six sites for water wells to supply isolated homelands and small settlements were selected within the northwest Aboriginal lands of South Australia. Satellite imagery, aerial photography, viewing of the sites from a light aircraft, on-ground...

This mineral promotional brochure reviews significant historical developments in South Australia's mineral industry and canvasses the currently recognised mineral potential within the State, for the benefit of local and overseas interested companies...

Established producers have taken advantage of export opportunities for gypsum, salt and dolomite. New developments include a graphite processing plant at the former Uley Graphite Mine and trial mining of micaceous iron oxide for pigments. Proposals...

The 2 sands are similar in major constituents but differ in rare trace constituents, in grain size and in state of oxidation. They are probably different parts of the same unit.

Brief review of the deposit is presented, including regional geology, ore deposit features, production, history, quality, value, reserves and mining methods. It is the largest known high quality nephrite jade deposit in the world.

This interpretation of magnetic and gravity data covering KINGOONYA was undertaken as part of an interpretation of the northern Gawler Craton, and was carried out without reference to any previous geophysical interpretation. Most of the work is based...

3 diamond and 15 rotary-percussion holes were drilled in 1987 by CRA within EL 1330 on the southern part of the Field (PSF), this licence having been granted to the company for the exploration of strata below 50 metres depth in the subsurface. The...

The following trends emerged : - an increase from 1986 of 28% in production to $50 million - a significant increase in Mintabie production and slight increases for Coober Pedy and Andamooka - a 53% increase in the average number of precious stones...

The following trends emerged: - an 27% increase in production of 13.5 million to $63.5 million, - again a significant increase in Mintabie production of $10.8 million, (38.2%) - 16.3% increase in Coober Pedy production of $3 million, - 8.5%...

Exploration for opal, carried out in an area of the Stuart Range located approximately 130 km north-northwest of Coober Pedy, has included a compilation of geological and opal occurrence data, photogeological interpretation of aerial photographs,...

Diamond exploration over two relinquished part EL areas located between Quorn and Hawker in the southern Flinders Ranges has comprised kimberlite indicator mineral and geochemical sampling of drainage channels situated on the eastern margins of the...

The Gawler Joint Venture partners (Dominion Mining and Resolute Resources) have been exploring three near-contiguous areas located in the north of the Tarcoola - Kingoonya district, seeking possible economic concealed epithermal/mesothermal...

The Mutooroo mine was the largest copper producer in the Olary Province, until its closure in 1914. Recent geophysical work and drilling have discovered a deeper massive sulphide body of over 8 million tonnes, averaging 1.66% Cu, with an unknown...

A large area centred on the Wilkawillina Gorge of Ten Mile Creek, in the central Flinders Ranges near Oraparinna, is being explored for possible buried economic zinc silicate (willemite) epigenetic or replacement mineralisation of Beltana type, as...
