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...

Drill holes from grid 6 520 000 to 6 521 000 mN and all eastings up to 707 000 mE; 6 521 000 to 6 522 000 and all eastings.

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...

Drill holes include those of the 3-1-XP series, where X=1 to 262.

Results of testing to formulate an accurate specification of the mineral processing equipment requirements. The test results a showed wide variance between samples.

Results of testing to formulate accurate specifications for the concentration plant equipment. Impact crushing trials in either a plant or near to a plant-sized mill are recommended in order to evaluate the alternatives to primary and secondary...

Copper extraction in percolation leaching was relatively slow because of the low porosity of the large rocks in the as-ripped ore. To obtain reasonable extraction rates, size reduction will be required. Agitation leaching of ground ore gave copper...

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...

Drill holes from grid : 6 520 000 to 6 521 000 mN, 707 000 to 709 000 mE.

Work included froth flotation, leaching, solvent extraction and stripping tests. Estimates of capital costs and operating costs were made for oxide and sulphide flotation plants and a more complex plant comprising acid leaching, solvent purification...

3 samples were investigated. These contained malachite, chrysocolla and atacamite in siliceous gangue with some calcite. Copper from Mount Gunson is amenable to sulphuric acid leaching to dissolve copper. About 90% of the copper was extracted from...

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...

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...
