A chemical survey of Dawesley Creek in the Brukunga Mine area has concluded that seepages from the southern mine waste dumps located alongside the creek contribute the greater proportion of pollutants (acidity, iron, aluminium, manganese, zinc,...

Possible economic gold and stratiform / stratabound base metal sulphide deposits, that had been surmised to have formed within certain reactive metasedimentary units in folded and faulted Cambrian strata lying between Mount Pleasant and Strathalbyn in...

Ongoing evaluation of the stratiform base metal potential of the Cambrian metasedimentary bedrock sequence, in an area located just to the east and north-east of Meningie, addressed a regional north-south trending, sinuous zone containing a number of...

Within the now relinquished portion of the licence area, four gravity traverses totalling 34.4 line km and 11 rotary mud drillholes for 593.2 m were completed by CRA in a search for possible sedimentary roll-front type uranium deposits formed within...

At the newly discovered Mount Torrens lead prospect, grid auger soil geochemical sampling, 1:5000 scale geological mapping, limited ground geophysical test surveying and the drilling of 23 percussion holes totalling 3388 m indicated the existence of...

In August 1966, a request for assistance with conducting pyritic sulphur exploration in the vicinity of Brukunga was received by the SA Department of Mines from Nairne Pyrites Pty Ltd. Brukunga is 29 miles east of Adelaide by road and 3.5 miles north...

South Australia has no known reserves of elemental sulphur. On the southern shore of Lake Eyre native sulphur occurs as nodules within crystalline gypsum resulting from micro-biological reduction of gypsum (Bonython and King, 1956; Baas-Becking and...

This investigation of the Brukunga mine site was prompted by the observed release of acid waters with high iron and other heavy metal concentrations into Dawesley Creek, the consequences of which could include possible pollution of Lake Alexandrina...

Work included a chemical survey of Dawesley Creek, analysis of soil samples from the Langhorne Creek area for evidence of concentrations of heavy metals, a lime neutralisation test, examination of soil characteristics for revegetation of the mine...

Ideal location - 26 miles from Adelaide - good climate. 3½ miles from Nairne on Adelaide-Melbourne railway line. Electric supply to Nairne-Power requirements could probably be obtained from supply company. Small flow permanent water beside deposit,...

The Brukunga mine site is a former open pit iron sulfide mine that continues to contribute to Acid and Metalliferous Drainage (AMD) into downstream waterways. Mine-based sources of AMD include the waste rock dumps and tailings storage facility. In...

A previous regional soil and stream sediment sampling program (cf. RB 2000/00002) has delineated areas of heavy metal contamination in the Dawesley-Bremer Catchment. Heavy metal contamination was found to occur sporadically along both Dawesley Creek...

A program of soil and stream sediment sampling was conducted along the Dawesley - Bremer Catchment to determine the extent and magnitude of potential heavy metal contamination downstream from the Brukunga Pyrite Mine. Arsenic, cadmium, copper and zinc...

As part of continuing exploration along the eastern Mount Lofty Ranges for economic Cambrian stratabound epigenetic base metal occurrences hosted within Kanmantoo Group metasediments, CRAE undertook a statistical study of existing surface geochemical...

As part of a regional search for possible economic buried Cambrian stratabound lead-zinc mineralisation, anomalous bedrock zones defined by aerial magnetic, radiometric and INPUT surveys and by stream sediment sampling were followed up with soil and...

Regional stream sediment sampling across the southern Fleurieu Peninsula (133 bulk samples), done outside the previously sampled Cape Jervis / Talisker mine area, failed to locate any base metal anomalies that might be related to subtle pneumatolytic...

The Geological Survey of South Australia has recognised there is great potential to explore for critical metals in mine waste materials across the state forming part of a new supply chain. This report has sampled waste rock, tailings and processing...
