Most of the geochemical copper anomalies outlined by soil sampling in the Mount Coffin Diapir area are attributed to secondary dispersion of copper by weathering from epigenetic sources of low economic importance. One anomaly, caused by mineralised...

Investigation of the site of a proposed hospital at Bedford Park (Flinders Medical Centre) included geological mapping, trenching, seismic refraction traverses, four cable tool holes and five diamond drill holes up to 29.5m deep. The work shows...

Drilled 12 holes aggregating 2240 feet.

Numerous base metal occurrences and historic mines occur in the Mt Lyndhurst area, hosted mainly in Neoproterozoic rocks of the Adelaide Geosyncline. Investigations at several prospects have included detailed mapping plus soil and rock chip sampling....

A number of base metal occurrences in the northern Flinders Ranges, previously classified as syngenetic, diagenetic and epigenetic in nature, appear to have resulted from metalliferous brine-sediment interaction with autochthonous and allochthonous...

During a one-month free appraisal period granted over certain current mining claims situated approximately 1.5 miles south-east of Copley, Horizon Explorations for its option take-up evaluation conducted prospect geological mapping at 1:2400 scale,...

A tenement area stretching for about 65 km eastwards from Hawker was taken up to explore for possible economic Cattlegrid-style base metal sulphides associated with a Neoproterozoic black shale sedimentary environment. Residual soils covering the...

Ground magnetic traverses carried out over prospective gold and base metal-bearing stratigraphic horizons in the vicinity of the abandoned Waukaringa Goldfield yielded several magnetic anomalies thought to correspond to massive pyritic ore in buried...

Base metal exploration carried out in the vicinity of historic copper workings in the Mount Rose area, situated approximately 30 miles east-northeast of Copley, has consisted of detailed 1:1500 scale geological mapping, soil and rock chip sampling,...

In August 1972 Cultus Pacific commenced exploring a number of historic copper prospects near Lyndhurst in the northern Flinders Ranges, with a view to assessing their feasibility for open-cut mining. The programme of work completed so far has...

Exploration of the area around the margins of the Oraparinna Diapir for commercial barite deposits has consisted of aerial photographic studies, plus ground geological traverses of photo-interpreted fault structures, and geological mapping, trenching...

Exploration for stratabound copper mineralisation in the Mount Lyndhurst area, allied with intensive prospecting of existing Mineral Claims and other historic base metal prospects and reported showings, has demonstrated a favourable geological...

An area located approximately 57 km east of Beltana was taken up to explore for possible economic hydrothermal/stratabound, replacement-type base and precious metal deposits in Neoproterozoic Callanna Group diapiric breccias and rafted dolomitic...

A consultant's technical review was received on existing recent exploration data originating from the SA Mines Department, for the Mount Coffin Diapir and its immediate environment. It was found that significant geochemical and induced polarisation...

Previously detected low-level geochemical anomalies for Cu, Pb and Zn were confirmed by follow-up stream sediment and soil sampling. Field inspections were made by helicopter of selected anomalous areas in the Upper Proterozoic and Lower Cambrian...

During exploration for possible economic stratabound base metal sulphides within the Upper Proterozoic Tindelpina Shale Member, 80 km east of Hawker, 647 samples of weathered calcareous black shale were collected along a 90 km strike distance as part...

The resumption of brownfields mineral exploration at the historic Kapunda copper mine and nearby prospects, undertaken by a new company, has targeted previously identified copper geochemical anomalies lying on the abandoned mine leases and along...
