During the current period, 25 holes/1042 feet of diamond drilling to check on discrepancies with previous downhole percussion drillhole ore sample assays reported from the Lagoon area, plus 31 holes/2780 feet of exploratory/appraisal percussion...

Ongoing evaluation work undertaken by Austminex at the Mount Gunson copper deposit has included geological mapping, rock rippability testing by bulldozer, the conduct of IP surveys, a further campaign of infill and exploratory drilling (726 holes...

This report presents the results of ore definition drilling derived from 60 percussion and diamond drill holes put down over the central and southern parts of the East Lagoon orebody, and gives the methodology for calculating currently mineable ore...

In December 1969, it was decided that the mining at Mount Gunson, scheduled to start in late April 1970, would commence with the development of the East Lagoon orebody. This orebody was selected because it appeared to contain the highest grade...

A test of the IP - resistivity methods' ability to detect and delineate a sulphide mass beneath the lagoon surface was deemed successful. SP and EM measurements gave no interpretable response.

Evaluation of the East and West Lagoon areas included 9348 feet of percussion drilling and an IP survey. The conduct of test SP and VHF EM surveys gave no interpretable response. The mineralisation is erratic, and concentrated at the Pandurra...

Reports describe the results of two attempts to use seismic refraction methods to map an unconformable subsurface interface between lithic sandstone and quartzite units within the Whyalla Sandstone. This palaeosurface is important as a locus for...
