As part of an ongoing search for MVT style base metal mineralisation within Lower Cambrian strata of the southern part of the Torrens Hinge Zone on Yorke Peninsula, in September 1975 112 RC holes for 1730 m were drilled at 500 m spacings along...

In continuing regional exploration conducted over north-eastern Yorke Peninsula, further reconnaissance stratigraphic drilling and wireline geophysical logging (in 3 vertical rotary percussion holes totalling 373 m) was carried out in May 1976 to test...

Minlaton Bore intersected 596 feet of Lower Permian (?lowermost Sakmarian) glacigenes and then a lower Middle to Lower Cambrian succession 2459 feet thick consisting in downward sequence of Ramsey Limestone (105 feet), red bed clastics (456 feet),...

Examination of drill cores from the Cambrian section of Stansbury West 1 indicates that the well intersected red bed clastics over the depth interval 1115-1950 feet KB, Parara Limestone from 1950 to 3315 feet, Kulpara Limestone 3315-5387, transitional...

2 diamond drillholes (total 518 feet) and 22 air holes (total 1851 feet) have indicated the presence of 28.5 million tons of Lower Cambrian limestone containing over 85% calcium carbonate in a bed dipping at about 10 degrees southwards, and below...

3 diamond boreholes (total 737 feet) and 8 air holes (total 1122 feet) were drilled in the Lower Cambrian Parara Limestone, half a mile south-west of Curramulka, to investigate the availability of commercial quality resources of limestone. Recovered...

This borehole was drilled to a total depth of 321 ft. 4 ins., and a complete cored section was obtained of the lower part of the Middle Cambrian Ramsay Limestone and of the Lower Cambrian Red Bed Clastics, in which thin bands of gypsum had been...

Ballast sources on southern Yorke Peninsula are listed and discussed with reference to quality and availability. Further work required to define reserves at each site is indicated. Cambrian limestones are available near Ardrossan and Curramulka but...

The Parachilna 1:250 000 map area is about 250 road miles north of Adelaide, South Australia, and includes the eastern shore of Lake Torrens, the central Flinders Ranges and part of the Lake Frome Plains. The ranges are composed of folded Adelaidean...

A site in Barunga Sandstone (Tent Hill Formation equivalent) located 2.5 miles south east of Nantawarra Siding has been selected for testing. Previous quarrying operations from this unit in the area have disclosed the presence at many sites of clay in...

Following the failure because of drilling difficulties of No. 4a water supply bore (to be used as a standby water supply for the township of Hawker) site No. 5 was drilled about 100 m south-west of the existing production bore No. 2 (see Fig. 1). The...

Exploration for possible Mississippi Valley style stratabound lead-zinc deposits hosted by Lower Cambrian carbonates in the Angepena area, 70 km north-east of Blinman, comprised regional and detailed geological mapping, reconnaissance stream sediment...

Geochemical exploration conducted over the width of central Yorke Peninsula between Curramulka and Minlaton was directed at finding potential Cu-Au deposits in Mesoproterozoic basement, and Mississippi Valley type Pb-Zn deposits in Cambrian carbonate...

Follow-up geological investigations to stream sediment and soil base metal anomalies earlier disclosed in the Ten Mile Creek area have concluded that the mineralised sources found for the two broadest lead and zinc anomalous zones do not indicate the...

An area located approximately 12 miles north of Quorn was re-issued to Kennecott over a reduced licence acreage, to permit further investigation of Cambrian Parachilna Formation and Wilkawillina Limestone strata which had shown anomalous copper, lead...

Reconnaissance geochemical exploration for possible economic stratiform copper deposits hosted by Adelaidean and Lower Cambrian sediments in an area of the northern Flinders Ranges located east of Blinman has consisted of aerial surveys,...

Reports describe the various Cambrian biostratigraphic horizons encountered in the bore, making comparisons and correlations with the Cambrian elsewhere in the Adelaide Geosyncline, particularly at Mount Scott Range, Sellicks Hill, Curramulka, The...
