The opal occurs 15 km S of Mintabie in both bedding plane partings and vertical joints in the Wallatinna Formation a basal unit of the Early Cambrian Observatory Hill Beds. Small quantities of precious opal were found but potential is limited.

The purpose of this data package is to provide end-users with the GIS datasets used for the 2009 modelling of mineral potential in the Northern Flinders Ranges. The package contains subsets of SA 1:100 000 scale surface geology (polygons) and...

XRD, X ray powder photography, electron probe microanalysis and ICP atomic emission spectrographic analyses were carried out on thermally altered rocks. The high temperature origin of the mineral assemblage in the more strongly altered rocks is...

The subject report gives the results of two aspects investigated by Amdel regarding the treatment of South Australian oxide copper ores, viz. 1) the collation of leaching data for various mineralogical types of copper ores, that are available in Amdel...

A rotary percussion drilling programme (8 vertical holes for a total penetration of 1920 feet) was undertaken at Netley Hill to look for economic copper and molbdenum mineralisation in a greisen (hydrothermally altered granite) body which has an...

Poorly described Lower Carpentarian basement ?basic igneous rocks, occurring over an area of approximately 65 square miles situated 3 to 8 miles east and north-east of Iron Knob, were investigated by BHP to establish their exact nature and to assess...

The source of anomalous lead and zinc in the Radford Creek area was traced to a ferruginous outcrop of Parachilna Formation limestone that is associated with a prominent shear and also lies near the contact with the Wilkawillina Limestone. Samples of...

Continuation by Aquitaine of its regional appraisal of the mineral potential in the Cambrian carbonate sequence on northern Yorke Peninsula, has recently involved them in acquiring and interpreting ground gravity and magnetic surveys, completing a...

Resumed exploration for economic stratiform base metal deposits within basal Cambrian and upper Adelaidean metasediments in the area of the Arden and Ragless synclines, 20 km north of Quorn, concentrated on geochemical prospecting and detailed, 1:2000...

The Third Plain zinc silicate (willemite) deposit, located 14 miles south-east of Blinman, has been newly assessed by North Flinders Mines for its economic potential. Originally discovered by Kennecott Explorations in late 1966, and evaluated by them...

In the Terowie - Whyte Yarcowie district, and in other nearby areas to the east and south-east, ongoing reconnaissance/infill stream sediment and bulk sampling of highland areas, plus detailed grid-based loam sampling of alluvium on lower-lying arid...

Following an evaluation of existing subsurface data, 9 vertical percussion holes totalling 670 m were drilled to test discrete gravity anomalies in the Mount Woods area, in a search for Olympic Dam type mineralisation. The holes encountered...

Continuing exploration of the geochemically anomalous (35-210 ppm Ni) Lower Proterozoic basement rocks previously identified by Kennecott at Blackfellow Hill has consisted of first laying out a 10,000' x 7200' prospect grid, before conducting soil...

The potential for finding remnant economic stratiform gold mineralisation in the Mannahill Gold Field was investigated by examining the old surface and underground mine workings, and the best-developed ore shoots were tested by drilling 25 vertical...

The possible untested economic base metal potential of a 10 mile long zone of airphoto-interpreted intense hydrothermal alteration of the Gawler Range Volcanics, which follows the Uno Fault near Margoon Dam, was investigated on the ground by sampling...
