In a continuation of diamond and base metal exploration of newly discovered carbonatite / kimberlite intrusive bodies in an area located immediately north of Orroroo, these bodies were examined petrographically and analysed to compare their...

Small deposits of manganite and pyrolusite occur within oolitic Etina limestone (Marinoan) on opposite limbs of a syncline south of Artipena Hill. The ore was probably found under oxidising conditions by secondary concentration of colloidal solution...

ABMINGA lies on the eastern edge of the Musgrave Block, which consists of Early to Middle Proterozoic gneisses and granites, intruded by dolerite dykes. A small area of folded and faulted Adelaidean and Cambrian sediments lies in the SW corner....

Reserves of 2500 tonnes (indicated) and 75 000 tonnes (inferred) is largely from no..2 Lode. Hand sorting is necessary to produce industrial grade.

Since 1972, 13.5 tonnes of copper ore have been handpicked from malachite and azurite on cleavage planes exposed in trenches in Tarcowie Formation siltstone of Marinoan age, 7 km south of Orroroo. The deposit was sketched, mapped and 9 samples taken.

Ongoing exploration for economic epigenetic and syngenetic copper occurrences in the vicinity of the Worumba Diapir, east of Hawker, has concentrated on field mapping, soil and channel sampling and shallow percussion drilling (47 holes for 3755+ feet)...

Exploration for copper mineralisation within an area centred immediately north-northeast of Kapunda has as its initial objective to find shallow deposits of oxide and carbonate ores similar to those mined historically at Burra and Kapunda, focussing...

Epithermal, fault-related gold and base metals in calcareous Adelaidean metasediments (cf. the Beltana and Aroona zinc-lead deposits), and sedex style base metals of Mount Isa - McArthur River type, or stratiform base metals in black shale units, were...

TARGET: Gold associated with major structures and hosted by calcareous rocks. EXPLORATION: Stream sediment and BLEG (bulk leach extractable gold) sampling at 22 sites. Au (by bulk cyanide leach), As and Fe analysis. RESULTS: Because no anomalous gold...

In the central Flinders Ranges, Neoproterozoic and early Palaeozoic rocks are found outcropping within a series of broad, open, dome and basin-shaped folds. This region contains most of the diapiric structures in the Adelaide Geosyncline, many, but...

Report presents a consultant's independent assessment of the petroleum potential and risked prospect status for PEL 41, using data provided by the licensee.

PEL 41 was granted to a deliberately SA-based new venture exploration company consisting of Chairman and well-known Emeritus Professor of Geology Eric Rudd, four other founding honorary and unsalaried directors, and 100 or so individual speculative...

Reconnaissance geochemical sampling of the eastern PARACHILNA mapsheet area for sediment-hosted base metal deposits has succeeded in locating several well-defined areas of interest, although approximately two-thirds of the SML area appears to be...

The Parachilna 1:250 000 map area is about 250 road miles north of Adelaide, South Australia, and includes the eastern shore of Lake Torrens, the central Flinders Ranges and part of the Lake Frome Plains. The ranges are composed of folded Adelaidean...

Despite the palaeoecological emphasis of most recent stromatolite research outside the USSR, controversy still exists regarding the environmental restriction of these organosedimentary structures and in some cases, analogies with modern occurrences...

Stratigraphic sections were measured in the Brighton Limestone and part of the upper transitional beds of the Tapley Hill Formation in quarries and natural outcrops at Brighton, Hallett Cove, Reynella, Noarlunga, Myponga, Orroroo and Tarcowie. Flat...
