Continuing exploration of the Aroona Valley and its vicinity for possible 'blind' occurrences of the zinc silicate, willemite, within host Lower Cambrian strata, has consisted of 1:4800 scale geological mapping of the south-western limb of the Aroona...

Shallowly buried, Cambrian stratabound base metal deposits of Mississippi Valley type, that might be associated with large throw old fault structures running along the western side of the Flinders Ranges, were sought by carrying out a varied programme...

In a continuation of the evaluation of the Mucatoona copper prospect, assaying of RAB drill cuttings samples returned no metal values of note. Mineragraphic studies of the primary copper mineralisation occurring in the Adelaidean black shale facies...

A geological and geochemical appraisal made of various mines and prospects in the Beltana area has sugggested that only those situated nearest the Nuccaleena Diapir are the most likely to yield drilling success in the search for significant extensions...

Ongoing exploration of copper prospects within diapiric raft blocks of Adelaidean metasediments at Beltana has concentrated on the vicinity of historic underground mine workings where evidence of primary sulphide mineralisation can still be seen at...

Outcropping Lower Cambrian carbonate rocks, plus Adelaidean diapiric rocks located west of the historical Mount Bayley copper mine, were tested for concealed base metal mineralisation by collecting and analysing 133 regional stream sediment samples....

A re-investigation of the remnant mineralisation potential of the Ediacara Mineral Field has involved a review of SA Department of Mines' (SADM) diamond drillhole data, the selective re-sampling of diamond drill core intervals for assay, detailed...

SML 113 covering about 1000 square km of Upper Proterozoic and Lower Cambrian sediments, and scattered masses of intrusive diapir, was taken out in the vicinity of Beltana to explore for copper deposits analogous to those found by SA Department of...

An area surrounding Beltana in the Flinders Ranges, which is known to contain low level base metal mineralised Adelaidean and Cambrian sedimentary rocks and diapiric intrusive structures, has been prospected by a combination of photogeological studies...

Exploration for Mississippi Valley - style Cu-Zn-Pb orebodies in the vicinity of the old Sliding Rock Mine, 15 miles east of Beltana, comprised detailed geological mapping, grid-based soil and outcrop sampling, interpretation of previous Electrolytic...

Results of rotary percussion / diamond core drilling of 3 holes (total penetration 532.2 m, of which 341.2 m was cored) near the Black Eagle mine on the western margin of the Cambrian Ediacara Sub-basin, plus a reinterpretation of previous drilling...
