An extensive orientation biogeochemical survey established that the copper content in the branch twigs of two wattle tree species, Acacia aneura and Acacia linophylla, is an indicator of near-surface copper mineralisation. A number of anomalies...

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...

All known copper occurrences in the area are located immediately above and below a disconformity in the Pernatty Grit Formation. Copper has been found to occur principally as malachite above the water table, and chalcocite below. Other minor forms...

During January and April 1966, 10,611 feet of reconnaissance and infill percussion drilling plus 300 feet of auger drilling were carried out on SML 96, around the former Main Open Cut and Lagoon workings of the historic Mount Gunson copper mine, with...

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...

An orientation survey found anomalous base metal concentrations in trees growing over Cattlegrid, but not over MG14. The source of higher metal concentrations at Cattlegrid is probably the bedrock geochemical anomaly which is due to the shallow water...

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....

Drill holes include Austminex percussion drilling at Millsite area (1966-1967), ABC grid series (1966), BGC (biogeochemistry) grid series (1967) from lines 94N to 22N, Ramsay 1, Waterhole 1, and Mount Gunson Mines percussion drilling (1971-1972 3-5-XP...
