An amphibolite-facies mica schist carrying syngenetic copper mineralisation has been mapped over a strike length of 2.5 km near Williamstown, 40 km North East of Adelaide, South Australia. The schist, termed the Ukaparinga Schist, contains...

Exploration for possible stratiform or hydrothermal, fault-associated copper deposits in the area of basal Adelaidean metasediments lying to the north of known such mineralisation at the abandoned historic Ukaparinga mine, immediately north of...

On February 9, 1954, Mr. J. W. Spooner of 25 Crewe Street, Henley Beach, reported an occurrence of uranium bearing ore along the Gorge Road, and submitted a sample for testing. A radiometric assay of this sample indicated a U3O8 content of 3.5%. The...

Two areas, the Archean inlier near Aldgate and an aerial scintillometer anomaly at Breakneck Hill were examined with a scintillometer. No radioactivity of any significance was located but the cause of the aerial anomaly in the second instance was...

A second occurrence of outcropping monazite on the northern side of Myponga Hill, which is situated about 2 miles south of Myponga township, was inspected and advice given to a prospector concerning how best to further develop the existing small-scale...

Government-led prospecting for economic uranium mineralisation, conducted in the Yankalilla area during June-September 1954, has consisted of detailed Geiger counter radiometric survey traversing of the outcropping Archaean basement rocks at 1 chain...

Exploration of the uranium discovery at Myponga has been completed. Diamond and wagon drilling, and underground exploration have shown that the mineralisation is too limited to warrant further development. Open cut and underground mining conducted at...

Copper carbonates are sporadically distributed throughout steeply dipping mica schist in a zone up to about 70 ft. wide. The host rocks have been regarded as overturned metamorphosed Burra Group (Torrensian) beds resting on the Aldgate Sandstone...

Three diamond holes drilled on the southern slopes of Mt Compass in a search for road-making aggregate encountered variably banded calc-silicate rocks, syenitic types and pegmatites of the Lower Proterozoic Barossa Complex. The required volume of fair...

The diamond and base metal potential is appraised based on recent company exploration for gold and diamond bearing kimberlites, with special reference to regional stratigraphy, tectonic structures based on the Echunga detailed low level aeromagnetic...

Report describes these unusual mineral deposits which are currently the only source in Australia of refractory grade sillimanite and filler grade mica.

A water balance study of the Piccadilly Valley has indicated that almost 20% of annual rainfall, amounting to 2000 ML, recharges the fractured rock aquifers. The current usage of about 1200 ML represents just under 60% of this annual recharge. Total...

The Torrens Rural Catchment can be divided into three zones where groundwater extraction from fractured rock aquifers is significant - the Fourth and Sixth Creek catchments, and the Birdwood - Gumeracha area. The Fourth Creek Catchment, which is...

The Tookayerta Catchment is an area which is increasingly coming under pressure from its landowners for the development of local groundwater resources to irrigate dairy pastures, berry plantations and vineyards. The catchment encompasses two...

This report summarizes information on 10 South Australian mineral deposits with individual aggregate gold resources and/or historic production of 1 tonne or more. By far the largest is the Olympic Dam Cu-U-Au-Ag deposit, with a measured and indicated...

A large, 722 square km area of the central Adelaide Hills extending between Jupiter Creek and the Warren Conservation Park is being explored for diamonds, gold and base metals, in host geological structures that appeared to be associated with...

Three potentially economic gold and platinum / palladium - bearing, known primary uranium-mineralised targets in the Palaeoproterozoic Houghton basement inlier have been evaluated through the conduct of office-based geological and geophysical studies,...

Possible primary gold and platinum - palladium mineralisation which might have formed in Palaeoproterozoic basic igneous rocks of the Myponga Inlier were the targets of exploration in an area 60 km south of Adelaide. Work undertaken comprised a field...
