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...

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...

Includes results of diamond drilling at Pernatty Lagoon to check reserves estimated from results of percussion drilling, and results of percussion drilling at the House workings to extend indicated reserves of run-of-mine grade sulphide ore....

Plans include drill hole locations and IP traverses, bedrock lithology, structure contours (top of Pandurra Formation, top of Whyalla Sandstone) and a grade control map.
