The Mount Gunson mine Main Open Cut workings are developed in a mixed sulphide - oxide orebody. Flotation of oxidized ores from this orebody fails to give economically acceptable recoveries, whereas flotation of sulphides gives excellent recoveries....

The included mineralogical reports and explanatory prior company correspondence give the results of, and rationale behind, a lengthy programme of mill product sampling and sample description for weekly to monthly process monitoring throughflow samples...

TARGET: Palaeo-alluvial diamonds in the Triassic Boolcunda Basin. EXPLORATION: Initial soil sampling and ground magnetic surveys of geochemical and geophysical anomalies; comprehensive regional and follow-up heavy mineral stream sediment sampling of...

TARGET: Possible diamondiferous kimberlites or secondary diamond deposits in the Warrakimbo area. EXPLORATION: Regional and follow-up geochemical sampling of gravels and soil, plus geological mapping and ground magnetic surveys, were carried out in...

TARGET: Diamonds, base metals, gold and precious metals in the Cradock-Carrieton and Orroroo areas. EXPLORATION: Regional drainage heavy mineral sampling, bulk sampling and costeaning, mineralogical and sedimentological studies, localised...

This study was commissioned by the Petroleum Division, Mines and Energy South Australia (MESA), and was completed in September 1995. Principal objectives of the study were to determine the timing and nature of any episodes of heating and cooling...

TARGET: Evaluation of the gemstone tourmaline and kaolin clay potential of the Dudley Pegmatite on Kangaroo Island. It is believed that this known occurrence of coloured tourmaline is one of only two locations in Australia which have produced...

A collection of Amdel petrographic reports providing raw data for a petrogenetic study of Cowell area jade specimens and related host rocks carried out by SADME, aimed at determining geological controls on the distribution of high quality nephrite...

As part of a regional search for economic uranium and copper mineralisation, the US-based company Kennecott Copper in November 1968 performed a semi-detailed airborne spectrometer survey of 550 line miles in the Shamrock Valley - Freeling Heights -...

TARGET: Gold in the Mount Finke region. EXPLORATION: A photogeological study, aerial magnetic and radiometric surveys, image processing of aeromagnetic data reprocessed by the BMR, a regional geophysical interpretation, ground magnetic traverses,...

Evaluation of the diamond potential of the Arckaringa area, 50 km south-west of Oodnadatta, which is here considered to be a region both tectonically and geologically favourable for the past emplacement of kimberlitic intrusive bodies, has comprised...

TARGET: Olympic Dam style base and precious metal deposits; iron ore; kimberlitic diatremes. EXPLORATION: Two aerial magnetic and radiometric surveys, a semi-regional gravity survey, and a helimag survey of possible kimberlite targets, plus ground...

Known fine-grained cassiterite vein mineralisation occurring at Prospect Hill was investigated via detailed geological mapping (at 1:1000 scale), ground magnetic surveying and the conduct of metallurgical testwork. Out of this work it was concluded...

Possible primary gold associated with buried Archaean metabasic lithostratigraphic units (greenstones) was the target of exploration undertaken in the Mount Christie - Mulgathing region. Work consisted of regional soil sampling at 2 km centres,...

Nephrite jade is associated with Lower Proterozoic dolomitic marbles and calc-silicate rocks as part of a sequence of metasedimentary quartzo-feldspathic gneisses, quartzites and mica schists of amphibolite metamorphic facies. These rocks normally...

TARGET: Possible epithermal gold and base metal deposits associated with volcanic centres; related hydrothermal alteration deposits; and diamonds. EXPLORATION: Regional and follow-up geochemical sampling (gravel, stream sediment and rock chip, plus...

TARGET: Phosphate occurrences in the Mid Sturtian from Port Pirie to Marree. EXPLORATION: Regional investigation of the occurrence, distribution and origin of phosphate by mapping of known phosphate occurrences and geological traversing across...

TARGET: Beryllium minerals associated with altered carbonate lithology contact aureoles to sodic granitoids emplaced in regionally metasomatised Lower Proterozoic metasediments. EXPLORATION: Reconnaissance rock chip sampling, and resampling of 197 CRA...

Exploration for possible epithermal uranium and base metal deposits as part of Marathon's Gunsight Project, in the northern part of the Mount Babbage Inlier around Prospect Hill, comprised orientation and regional rock chip, stream sediment and soil...

Arising out of exploratory drilling carried out by Ironclad Mining in 2012, which aimed to test the shallow subsurface haematite ore potential of an ironstone outcrop located in the central north of the Wilcherry Hill licence area, an unexpected...
