High precision geochronological analyses of metamorphic and inherited magmatic zircon grains, which were obtained from stored percussion drillhole samples of a garnet gneiss that occurs within the Commonwealth Hill magnetic anomaly, north-western...

The orebody at the Challenger gold mine shows remarkable down-plunge continuity, from the surface to some 1400 m vertical depth, which is geometrically equivalent to a down-plunge length of ~2800 m. However, at ~220 RL within the mine, the orebody is...

Our knowledge of geochemical dispersion of gold and gold pathfinders in the Gawler Craton (South Australia) is poor since there have been very few published research or orientation studies. In this study conducted at the Birthday gold prospect, the...

In a continuing regional search for Proterozoic or Archaean basement-hosted base and precious metal deposits, 17 geochemical sampling traverses spaced at about 1 km intervals, and covering 34.5 line km of the Gawler Range Volcanics, Glenloth Granite...

TARGET: An assessment of the potential for uranium and lignite deposits within the Eocene Pidinga Formation, and separate investigations of coincident, possible Olympic Dam target type magnetic and gravity anomalies in the crystalline Precambrian...

The licence was relinquished following conduct of intensive exploration in the Malbooma area since 1973. Drilling of 514 percussion holes (totalling 21 355 metres) and 29 cored holes (totalling 1 111 metres) defined widespread uranium mineralisation,...

Migmatites are complex, high-grade crystalline rocks that have formed by partial melting. They have been recognised within the crustal rock record across most of geological time, are seen to be developed in various tectonic settings, and can affect a...

The subject field excursion performed in August-September 2000 in part mimicked that held by the GSSA during September 1997, but included 6 additional stops programmed for Day 1 (31st August 2000) to examine Archaean geology at the southern tip of...

Portions of regional airborne radiometric and magnetic surveys, plus a small part of the HW-IV seismic refraction traverse, and 20 line km of gravity and ground magnetic surveys, were undertaken by joint venture operator Afmeco as part of its Project...

Following the partial relinquishment of 481 square km of EL 859 on 30/3/1983, exploration continued for stratiform Pb-Zn within the Carpentarian Tarcoola Beds within an east-west trending trough, or half-graben, seen on magnetics in the Wilgena Hill...

Interest in an area near Mount Christie Siding was stimulated by the 1993 MESA Barton Bedrock Drilling Programme, which detected anomalous gold, chromium, base metals and platinoid metals in layered ultramafics. Initially, tenement-wide calcrete...

Following initial assessment of available data, exploration for copper, gold and base metals in an area 60 km west of Tarcoola concentrated on regional calcrete sampling. Analysis for gold and a suite of base metals indicated several areas of...

Regional calcrete sampling carried out 100 km south-west of Tarcoola disclosed weak gold anomalism in the south-eastern portion of the licence, coincident in part with gravity and aeromagnetic features. Detailed follow-up sampling is warranted.

In response to the recognition of unusual mafic and ultramafic rock types in the Mulgathing area by Kennecott Explorations during their tenure of SMLs 261, 333 and 491 between 1968 and 1971, diamond explorer Otter Exploration has carried out further...

The area lying immediately south of lakes Gairdner and Harris was considered prospective for concealed Olympic Dam style Cu-Au mineralisation hosted in Archaean to Mesoproterozoic basement rocks of the Gawler Craton. Acquisition of a regional 1 km x...

Calcrete sampling over a previously sampled area 100 km north- northeast of Tarcoola delineated two low order anomalies peaking at 8 and 9 ppb Au.

Exploration for possible Proterozoic intrusive-hosted Cu-Au deposits in an area 60 km north-west of Tarcoola included regolith landform mapping and regional calcrete sampling. No significant anomalies were identified within the relinquished area.

Regional calcrete sampling was undertaken 55 km north of Tarcoola, looking for regolith indicators of possible mineralisation associated with Gawler Range Volcanics, Hiltaba Suite granites and Mulgathing Complex rocks. Two anomalous gold values of 28...

Initial investigations undertaken in the Garford area, 170 km north-west of Tarcoola, comprised lag and soil geochemical sampling, ground magnetic surveying, and petrographic descriptions of outcrop samples. Follow-up aircore and RAB drilling (78...

Gold and base metal mineralisation hosted by Archaean gneisses of the Mulgathing Complex and Proterozoic Hiltaba Suite granites was the target of exploration in an area 100 km west of Tarcoola. Regional calcrete sampling on a nominal 1 km grid...
