2 million tonnes of low grade 0.64% Cu ore is about to be covered with overburden. At present copper prices, both heap leaching in the open pit area and in situ leaching would result in an annual running cost deficit of about $155 000 - $160 000 per...

1:25,000 scale geological mapping and scout stratigraphic drilling (9 vertical rotary holes for a total penetration of 758.5 m) have outlined the general distribution of Adelaidean rocks in the Lake Macfarlane and Island Lagoon areas. Perhaps the most...

During the period from January 1974 to March 1976, 35 vertical rotary percussion water wells were drilled and many were cased off, perforated and then fitted with submersible electric pumps and offtake piping, to supply mine process water to the Mount...

The results of 1185 line km of aerial EM surveying carried out in the vicinity of Winnie Pinnie Dam, 85 km north-west of Port Augusta, using the Barringer INPUT system, have been interpreted as a possible means of identifying prospective Adelaidean...

Includes geological logs for the following drillholes: Mount Gunson to Canegrass Dam area: 3-14-1P to 3-14-46P (Mount Gunson Mines, 1972). Canegrass Dam area: 3-14-19P to 3-14-41P (Pacminex, Feb 1972); TOC1 - TOC4 (Pacminex, Nov 1976); SP1 -...

Five semi-detailed gravity traverses run over a 2 mGal regional anomaly on EL 186 near Pandurra Homestead have indicated that the residual smaller anomalies are probably related to basic igneous intrusions and volcanic flows, rather than to the...

This report is intended to be a convenient single reference to the Cattlegrid ore deposit geology. It represents an updated summary of a large amount of data, gleaned largely from internal company reports. The subject matter relates mainly to the...
