During base metal exploration conducted in the hills on the eastern side of the Springfield Basin, just south of Cradock township, minor copper and lead anomalies were disclosed by regional stream sediment sampling (1090 samples assayed). There...

The near-surface base and precious metal potential of several possibly gossanous ironstone outcrops, that exist within a north-east trending broad domal structure in the Umberatana Group extending for 5-15 miles east of Yunta, were tested by limited...

Orientation geochemical sampling, and 1:25,000 scale geological mapping that included long sectional mapping of four railway cutting bedrock exposures in the Eudunda area, revealed pervasive low grade stratiform copper mineralisation in Sturtian...

Exploration for possible economic stratabound / hydrothermal deposits of base metals and perhaps also uranium, within a large area surrounding Peterborough, has consisted of field inspection and rock chip geochemical sampling of known historic mines,...

Work carried out at the Ajax and Waukaringa mine prospects included an aerial reconnaissance, grab sampling of mine tailings heaps and limited detailed stream sediment sampling plus, at the Ajax prospect, the drilling of 5 vertical rotary percussion...

Exploration of two small licence subareas centred respectively 18 km east of Yunta and 29 km south of Manna Hill consisted only of the collection, during preliminary field reconnaissance traversing, of 221 surface rock chip and soil samples to send...

It has lately been shown that the gold grades previously determined from a standard laboratory analysis of grab, rock chip and channel samples collected from Mount Grainger Goldfield may be unreliable, due both to the ore mineralogy and to the patchy...

Mapping and sampling of 39 adits at Mongolata Goldfield has ensured that a permanent record of the 1930s mines is available for historical and exploration purposes. Many of the workings are no longer accessible. Details of the production history of...
