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...

Stratabound, chemically precipitated Telfer - type replacement style vein gold was the target of exploration undertaken over an area 25 km north-west of Yunta, which contains good exposures of Neoproterozoic Umberatana Group clastic metasediments that...

Copper and gold exploration comprising outcrop, stream sediment and soil geochemical sampling, and the conduct of ground magnetic and IP surveys, plus RC percussion (67 vertical holes, total 6624 m) and diamond cored tail drilling (in 2 holes, total...

Investigation of part of the nose of the Mount Grainger Anticline where minor gold and copper occurrences are known, and anomalous Au, Cu, Pb, Zn, Co, Mn, Ba and Fe values have been detected by stream sediment surveys. 692 soil and 63 rock chip...

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.

Investigation of the Upalinna Diapir, located 20 km east of Wilpena Pound in the Adelaide Geosyncline, has identified a number of structural and sedimentary features normally associated with evaporite diapirs. The Upalinna Diapir is a small,...

Fully HQ/NQ cored SADME stratigraphic drillhole Mount Rufus 1 was sited on the western margin of the Karinya Syncline to investigate the nature of the Adelaidean - Early Cambrian Normanville Group contact, and the mineral potential of the area. It...

This report summarizes information on 10 South Australian mineral deposits with individual aggregate gold resources and/or historic production of 1 tonne or more. By far the largest is the Olympic Dam Cu-U-Au-Ag deposit, with a measured and indicated...

A large, 722 square km area of the central Adelaide Hills extending between Jupiter Creek and the Warren Conservation Park is being explored for diamonds, gold and base metals, in host geological structures that appeared to be associated with...

A multi-licence project area centred on the historic abandoned Burra copper mine is being explored for possible economic, buried Burra type copper oxide and copper carbonate mineralisation that may have formed within Neoproterozoic metasedimentary...

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...

Investigation of the quartz - (sulphide) gossan vein systems within Proterozoic metasedimentary bedrock at the alluvial Teetulpa Goldfield north of Yunta, for stratigraphic and structural clues to loci of primary gold mineralisation elsewhere in the...

Exploration of an historic gold mining field and surrounding area located approximately 20 km north-east of Burra and situated due west of the Delamerian Bendigo Granite batholith has targeted possible unexploited fine-grained gold, thought to exist...

TARGET: Cross-cutting gold mineralised quartz reefs / veining, primarily in the Tarcowie Siltstone; gold in known mineralised zones in the Saddleworth Formation; and circular features as outlined from Landsat image interpretation. EXPLORATION: Rock...

TARGET: Telfer-style gold in the Wabricoola area, NW of Yunta. EXPLORATION: Image processing of BMR airborne magnetic survey data, and detailed stream sediment (452) and soil (110) geochemical sampling. RESULTS: Anomalous low order gold values that...

Exploration undertaken to search for Telfer - style Proterozoic stratabound gold, within a large area extending to the north and north-west of Manna Hill township, included an aerial photographic survey of known occurrences, and helicopter-assisted...

Increase in gold reserves of the Manna Hill Goldfield was not substantiated. Exploration included study of all old mines and prospects, detailed geological mapping and photogeology. Stratigraphic or structural extensions or repeats were not located....

Hallmark Gold's Manna Hill Gold Project comprises EL 1436 and ELA 295/87. The area under licence covers many old gold mines including the Aurora Australis, Birthday, Nectar, No Gammon, Trojan, Odd Trick, Euro, Klondyke and Royal Charlie gold...

Exploration for possible stratabound gold has included detailed geological mapping, at 1:20,000 scale, which was focussed on the Tapley Hill Formation - Tarcowie Siltstone stratigraphic contact. An attempt was made to identify the bedrock source of...
