Two additional phases of the drilling program to assess the groundwater resources in the Clare Valley were undertaken during March 1998 at Wendouree (Phase III), and during July 2000 at Wendouree and Watervale Oval (Phase IV). The Phase III program...

The Clare 1-mile mapsheet area is situated about 70 miles north of Adelaide, South Australia, in partly hilly agricultural and pastoral country. The oldest Adelaide System (Proterozoic) rocks are the phyllites, quartzites and dolomites of the River...

Shallow surveys to investigate the subsurface material below 2 potential dam sites indicates that problem areas exist where possible shear zones and basement infills occur. Backhoe pits indicate that in landslide areas, the depth to bedrock may exceed...

Investigates rippability of near surface material at edge of the South Para Reservoir, and along proposed channel joining South Para and Warren reservoirs. 13 shallow drill holes are recommended.

Shallow seismic survey of 10 spreads indicates 4 of 6 sites are rippable.

Kaolin deposits at Birdwood, 48 km NE of Adelaide, are a commercial source of well-crystallized kaolinite formed in medium-grade metamorphic rocks equated with Saddleworth Formation of Adelaidean age. The kaolin appears to have formed by weathering...

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

A fundamental question remains to be answered in the Clare Valley. How much water can be safely extracted without causing depletion of the groundwater resources? This question is being addressed by a major investigation into the groundwater...

Phase Two of a drilling program at Clare, South Australia was undertaken in June, 1997. A total of 6 bores were drilled, 4 of these at existing locations established during Phase One drilling in January, 1996, and a further 2 at Watervale Oval as...

The Torrens Rural Catchment can be divided into three zones where groundwater extraction from fractured rock aquifers is significant - the Fourth and Sixth Creek catchments, and the Birdwood - Gumeracha area. The Fourth Creek Catchment, which is...

The Brownhill Creek Catchment can be divided into two main zones - the Hills Zone (rural catchment) and the Plains Zone (urban catchment). The Hills Zone is underlain by fractured rock aquifers which contain good quality groundwater (salinities...

This report summarises the main consumers, reserves, production and probable life of current mines and identifies potential alternative sources. Shale reserves in the currently worked pits are sufficient for 50 years, white plastic clay at Golden...

Two bulk samples from high-grade kaolin zones in ABC Ltd South and ABC Ltd North pits were taken to test the suitability of the <2um size fraction for use as a coating clay. The samples gave a relatively high yield of <2um size particles which...

Twenty-three vertical open RC drillholes with a total penetration of 2663 m were drilled by MESA during February and March 1995 along four W-E traverses in the Stonefield area near Truro, to determine bedrock geology and geochemistry below sedimentary...

Clay resources in the Roseworthy - Sheaoak Log - Freeling area, 50km northeast of Adelaide, were investigated as a potential source of raw material for brick manufacture. Twenty three auger holes totalling 242 metres outlined areas of weathered...

Eighty three reverse circulation drill holes totalling 2615.5 metres were drilled on Quorn, Orroroo, Paratoo and Carrieton 1:100 000 sheets to determine bedrock geology and geochemistry below sedimentary cover. The program is a part of the South...

Basal Umberatana Group glacial tillitic sedimentary sequences and upper Burra Group interglacial arenaceous sediments were explored for possible economic stratabound gold mineralisation in an area located about 10-40 km north-west of Burra. In the...

Exploration for possible Neoproterozoic sediment-hosted, unconformity related buried uranium deposits within a synclinally-exposed area of reduced Warrina Supergroup siliclastic rocks, 160 km north of Adelaide, followed a concept that such deposits...
