TARGET: Mid-Proterozoic acid volcanic - hosted copper mineralisation in the Moonaree area of the Gawler Ranges, 120 km south-southeast of Kingoonya. EXPLORATION: Elevated base metal geochemical anomalies identified on the north-west flank of the...

This report is intended to be a convenient single reference to the Cattlegrid ore deposit geology. It represents an updated summary of a large amount of data, gleaned largely from internal company reports. The subject matter relates mainly to the...

During Year 12 of the Olary JV Project (2008-2009), field work was undertaken only on EL 3849 Outalpa to make up for the earlier underspending on that licence relative to commitments. In early 2009, a ground radioactivity survey was acquired using a...

Sandstone wedges observed at the palaeosurface of the Pandurra Formation in the Cattlegrid copper deposit are diagnostic of palaeopermafrost action. The breccia profile formed at Cattlegrid within the Tapley Hill Formation, both at mineralised...

Grain size analysis and cross bedding data from the Pandurra Formation indicates it to be of fluvial origin, while packing and compaction of the grains suggests considerable of quartzite has been removed by erosion. Ripple marks, truncation of sandy...

One vertical stratigraphic diamond drillhole [the 1a re-drill] was fully cored to 1450 m total depth over a regional gravity high in the western half of the licence which was thought to be prospective for Olympic Dam type polymetallic mineralisation...

The aim was to differentiate, using microscopic traits, the McLeay Beds from the Tapley Hill Formation lying above it, and the Pandurra Formation below. The formation boundaries as established by petrography are at variance with the stratigraphic...

Airborne and ground geophysical surveys were undertaken in the Billa Kalina area, prior to commencing to drill in a search for Olympic Dam type Cu-U-Au mineralised haematitic breccias, in order to delineate and detail several broad magnetic anomalies...

Minlaton South 1 was a shallow stratigraphic test well drilled by Beach Petroleum to investigate a possible ?Archaean basement high subcropping 3.75 miles south of Minlaton township, as suggested by SADM regional mapping observations made during 1961....

The Mount McTaggart prospect is located 15 miles south-west of Arkaroola Base Camp and 3 miles west of the Arkaroola-Balcanoona Road. A programme of ten rotary percussion holes totalling 3457 feet commenced on 11/10/1971 and was completed on...

Correlates Troubridge Basin Permian biostratigraphic units with those of the Maitland Group from the Sydney Basin (Hunter Valley region of NSW). Minlaton 1 penetrated 600 feet of Permian glacigenes, deposited under glacial or coldwater deltaic...

The late Palaeozoic Cape Jervis Formation of the Troubridge Basin in southern South Australia provides a sedimentological record of the glacial environment during the Permo-Carboniferous glaciation. The sedimentary sequence is divided into five...

A new generation, first edition WINTINNA 1:250 000 scale geological map and explanatory notes have been published. These documents represent the conclusion of the Geological Survey of South Australia's geological mapping program undertaken in the...

Ten glacial megaclasts, unique perhaps from a global perspective, have been identified in the half-graben rift of the MacDonald Corridor. The MacDonald Corridor is the most easterly of four half-grabens containing Neoproterozoic low-grade...

A survey of rock materials suitable for construction purposes showed that the most likely sources are Recent alluvial accumulations, suitable for foundry and concrete sand, and Permian fluvio-glacials which are used for local road-building. Drilling...

The Quaternary Era includes the two periods known as the Pleistocene and the Recent (or Holocene). The Era, although relatively brief in the geological time sense in that it extends back for only about two million years, provides a vast amount of...

The Arckaringa Basin, situated, in northern South Australia, is an intracratonic Permian basin, composed of deep marginal grabens or half grabens and a central area of shallow basement, the latter covered by only a thin sediment blanket. The...
