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...

The proposal to mine 4 orebodies of the Mount Gunson copper deposit is examined with respect to plant design, capital and operating costs and estimated ore reserves. A sequence for stripping waste, stock piling oxide ores and mining sulphide ores is...

The geological and geophysical basis for determining that the ore reserves were sufficient to allow mining to start on the East Lagoon and West Lagoon orebodies at Mount Gunson is detailed in the subject reports, and the likely technical causes of...

Investigates the likelihood of mineral concentrates becoming oxidized and liberating toxic sulphur dioxide gas during their transport to Japan. The sample examined is quite stable, but is not representative of the concentrate likely to be produced...

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...

During the subject licence period, 7 diamond coreholes for 406 feet total penetration and 15 rotary drillholes totalling 282.5 feet were drilled by the Mount Gunson Project's new owners, the CSR / United Uranium consortium, to check the existing ore...

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...

Drill holes include:. House sheet - ABC grid series, R series (1966, Austminex) - 3-3-XP series (1971-1972, Mount Gunson Mines) - BGC grid series, lines 45 to 305 (1967) and south of Town sheet (1967, Austminex) - MN grid (1967-1968, Austminex). Main...

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.
