Lower Proterozoic crystalline rocks of the Willyama Complex include phyllite, carbonaceous slate, mica-sillimanite schist and gneiss, feldspathic meta quartzite, quartzo feldspathic gneiss, calc-silicate rocks and iron formations. The oldest rocks in...

266 summary sheets on significant lead-zinc occurrences and anomalous concentrations have been prepared by the Department's Lead-Zinc Taskforce as a data package, in the form of 5 reports, to assist in the search for lead-zinc deposits to provide...

The Mannahill area has been prospected and mined since 1881, with ore being treated at numerous locations and by several processes. Gold occurs sporadically in quartz veining over 70 square km. The maximum depth of any working is < 80 metres on the...

Twenty-three vertical open RC drillholes with a total penetration of 2663 m were drilled by MESA during February and March 1995 along four W-E traverses in the Stonefield area near Truro, to determine bedrock geology and geochemistry below sedimentary...

The giant Olympic Dam deposit has a total resource of about 2 200 million tonnes grading 1.4% Cu, 0.5 kg/t U3O8, 0.5 g/t Au and 3.1 g/t Ag. Development of Olympic Dam, with current annual production of 67 000 t of copper and further expansion...

The mine was worked between 1935 and 1939. and recorded production totals 296.16 tonnes for 5007.4 grams of gold bullion. Gold occurs in gently west dipping Tertiary gravels overlying steeply east dipping Adelaidean Aldgate Sandstone. An indicated...

Gold was discovered near Earea Dam 50 km SE of Tarcoola in 1899. Production to date totals 59 237.59 grams of gold bullion from 1869.63 tonnes of ore, with an average head grade of 35.33 g/t gold. Gold-bearing quartz was mined from an east-dipping...

This records the history and production of various mines, occurrences and prospects in the Waukaringa area outside the main Waukaringa Goldfield, from 1873 to 1989. Apart from that obtained from the goldfield proper, 83 856 grams of alluvial and reef...

Production since 1912 totals 5206.4 grams from 146.3 tonnes of ore with average head grade of 35.6 g/t gold bullion. Gold was won from shear zones and ferruginous quartz veins within Archaean Kenella Gneiss. Sub-vertical shear zones and quartz veins...
