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...

Sampling was aimed at determining influence of copper mineralization on groundwater geochemistry. Although carbonate rich host rock and mine dewatering have minimized any heavy metal dispersion halo, a sulphate dispersion halo is centred over the...

The Worumba Anticline is a regional fold in the gradational zone between the Olary Arc and the broader folding of the central Flinders Ranges. The limbs of the anticline comprise complete upper Adelaidean successions, of which the Holowilena...

Fracture data taken from the excavated batters of the quarry was studied stereographically. It is concluded that the vertical batters are stable and will not suffer large scale planar failure.- Quarry floor foundation conditions are acceptable for the...

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...

Extensive literature and geological and geochemical field investigations of historic mines and prospects at the Mount Grainger and Oodla Wirra Goldfields have failed to disclose any remaining economic gold occurrences. The sparse native gold occurs...

At the Paratoo mine, copper is present in a zone at least 1000 feet wide, possibly over a strike length of about 1350 feet. It is not yet known over what proportion of this area copper occurs in workable amounts. Opencuts have exposed two main lines...

The PARACHILNA map area (31 to 32°S, 138 to 139.5°E) occupies the central Flinders Ranges which are made up of folded, mostly marine sedimentary Neoproterozoic and Cambrian rocks of the Adelaide Geosyncline, and adjoining plains underlain by Cainozoic...

This investigation was a feasibility study, therefore environmental factors are dealt with in much more detail than would be necessary in a routine geochemical report. Apparently these factors has little significant effect on the results. Spot...

A government investigation of the economic potential of the abandoned historic Burra Burra copper mine was started in December 1961. The SA Department of Mines (SADM) initial work comprised 1:1200 scale geological mapping of the old mine area,...

A programme of stratigraphic section measurement is envisaged in order to facilitate rock correlation and help outline the pattern of sedimentation in the Adelaide Geosyncline. In many areas measurement may be made on air photo enlargement, as has...

Geological mapping shows that the reservoir area consists of Torrensian siltstones, dolomites and quartzites. These are strongly jointed with a pronounced slaty cleavage. The joints form three distinct sets. The geological structure is of uniformly...

The Spalding inlier is a lens-shaped area of tightly-folded Willouran rocks of the Adelaide System (Upper Precambrian), extending north-south for about 10 miles; it is about 100 miles north of Adelaide. The rim of the inlier is marked in most places...

Within a small licence area centred about 15 km south-south-east of Burra township in the northern Mount Lofty Ranges, Copper Range initially targeted near-surface copper oxide mineralisation associated with an altered and brecciated contact zone...

A small area centred ~5 km west of Burra township is being explored for possible buried economic, Monster mine type stratiform copper oxide or copper carbonate deposits, thought to be associated with poorly exposed fault structures and related...

The rolling hills, wheat paddocks and vineyards of the Mid-North region of South Australia conceal a geological transition between the Adelaide Hills and the Flinders Ranges. Here the landscape is subtly controlled by the Neoproterozoic bedrock...
