The mineralised ore zone at Cattlegrid occurs above a buried land surface of the Pandurra Formation quartzite bedrock. The sulphide mineral depositional sequence shows progressive enrichment in copper at the expense of iron or primary mineralization....

Summary of geological knowledge to date, including mineralogy, paragenesis and ore handling problems.

Drill holes OK81 to OK106 located MG14 type deposits in Tapley Hill Formation outliers near Birthday and 3.5 km SE of Bellamy Wells. The area has potential for other syngenetic deposits but more stratigraphic information is required.

Includes geological logs for the following drillholes: Mount Gunson to Canegrass Dam area: 3-14-1P to 3-14-46P (Mount Gunson Mines, 1972). Canegrass Dam area: 3-14-19P to 3-14-41P (Pacminex, Feb 1972); TOC1 - TOC4 (Pacminex, Nov 1976); SP1 -...

16 diamond drill holes tested the distribution and grade of copper mineralization occuring in the Woocalla shales. Drilling results suggest that no economically viable copper deposit exists in the Gully due to the low grade, high overburden and...

Incorporates the results of mapping in the No. 1 Shaft, Cattlegrid mine, and of logging of the 3 horizontal drill holes collared from Drives 3 and 4. Data is also given on the fracture mapping (fracture counting and mineralized fracture orientations)...

Geological, mineralogical and sulphur isotope studies point to 3 distinct periods of mineralization, and suggest that the bulk of the sulphides in the 6 areas examined have precipitated from sulphide of biological origin.

4 specimens were examined for stratigraphic identification.

Geological mapping indicates that the Magazine Hill clay deposit belongs not to the Tregolana Shale, but to a claystone unit at the base of the Whyalla Sandstone. Extensions of the deposit could occur beneath a small plateau of Whyalla Sandstone...

14 cored holes have intersected copper mineralization in shaley facies of the Woocalla Dolomite, and extending up into dark claystone at the base of the Whyalla Sandstone. The mineralised rocks occupy a shallow depression in the post-Pandurra erosion...

Samples examined for stratigraphic identification.

During ongoing exploration for Mount Gunson style economic base metal mineralisation buried on the south-central Stuart Shelf, new work completed by CSR has included the drilling of 59 rotary percussion holes totalling 3782 m in the Winnie Pinnie,...

As part of continuing brownfields exploration for extensions to known stratiform base metal mineralisation in the area lying to the west of Pernatty Lagoon, much stratigraphic drilling (210 rotary percussion holes totalling 12,441 m, including 1167 m...

Aerial electromagnetic surveys using the Barringer Mark V 'INPUT' System were flown by CSR Ltd in the vicinity of Mount Gunson in three sorties during 1973 (260 line km), 1975 (3686 line km) and 1977 (1150 line km), in an attempt to remotely locate...

Formation responses in 12 drill holes were studied. SP and PR logs were run for only 6 holes because of highly saline groundwater conditions. No meaningful electrical logs were obtained.

Discusses the influence of sedimentary structures, weathering and mild tectonism on the development of breccia types, the relationship of mineralization to faulting and fracture systems, possible sources of base metals and sulphur and consequent...

A study of formation responses in 22 drill holes.

Ongoing appraisal work conducted by CSR at the company's newly discovered Cattlegrid copper deposit that lies at the top of the Pandurra Formation has included infill rotary percussion and diamond drilling (13 holes for 554 m, including 166 m cored),...

Near Pandurra Homestead on eastern Eyre Peninsula, dispersed secondary copper mineralisation occurs in faulted Upper Proterozoic sediments, along which some 30 shallow pits, probably dating back to the late 1800s, have been sunk. In an effort to...

BHP took out SML 204, covering 970 square miles located due east of the northern Middleback Range, for 2 years from 1/7/1968. The prime objective was to explore there for uranium and copper mineralisation. Work undertaken can be summarised as...
