In a regional soil sampling survey over Willyama Complex rocks on parts of the Outalpa 1:50 000 Sheet, 2443 samples were collected at 25 metres intervals on 54 lines roughly 1km apart. These samples were analysed for CU, PB, Zn, Au, Mn, Mo, Co, Ni, V,...

History from 1884 when silver, lead and copper were discovered in the Rapid Bay area.

Indicated 30 880 tonnes of tailings containing 1.72 g/t gold and 171 ppm copper remain. 80% of gold is extractable, but cyanidation or mercury amalgamation not allowed, due to water catchment area.

Specimens from the Mt Grainger Goldfield include quartzites, sandstones in which kaolinite is believed to represent earlier feldspar, siltstones, shales, diamictites of probable glaciogene origin, granitoids and andesites. Low to moderate temperature...

Between 1901 and 1916 gold ore from Mount Grainger Goldfield, 10 km north of Oodla Wirra, was treated by battery amalgamation and cyanidation at the Mount Grainger Mine. Tailings and slimes from this ore processing period still remain on site, and...

Brief description of the workings and historical outline from daily newspapers and Mining Reviews. Since discovery in 1899, 371.07 tonnes of ore have yielded 35 923.91 grams of gold bullion, ore being treated at Mount Torrens and Peterborough...

Gold recovery is variable. From 1956 - 1983, total of 2 719.97 tonnes of ore were treated and 35 841 grams of gold bullion recovered. Total ore crushed since operations began in 1897 is 14 808.45 tonnes. Total gold bullion recovered is 349 868 grams....

Orama Hill gold mine, also known as Koonamore Goldfield or Butlers Claim recorded production since 1930 of 808.89 grams of bullion. The mine is on the steeply dipping, sheared, axial plane of the Orama Hill anticline, in sandstone, siltstone and shale...

Alma and Victoria and Alma Extended, reportedly treated 60 000 and 2 834 tonnes of gold ore respectively. Tailings remaining on site contain minimum 37 710 tonnes grading 2.71 g/t gold and 1 080 tonnes grading 1.94 g/t gold respectively. Attempts in...

Discovered in 1890, mine has recorded production of 5 464 tonnes which yielded 262 185.90 grams of gold bullion. To determine gold content and tonnage, 5 hand auger and 2 shallow holes were drilled on the dumps. On site are 4080 tonnes of tailings...

Gold was first discovered in 1873. Most work was done before 1900 with the Alma and Victoria producing the bulk of the gold. Recorded production from the field was 58 226.46 tonnes yielding 1 426 665.22 grams of gold bullion, i.e. 24.50 g/t Au. 39...

Stockpiles of tailings from abandoned gold mines are small and probably do not warrant retreatment individually. Total of 71 000 tonnes of tailings are at Government Battery sites at Mount Torrens, Peterborough, Glenloth, Tarcoola and Mongolata. The...

These 2 largest mines on the goldfield, reportedly treated 54 810 and 2 302 tonnes of ore on site during the late nineteenth century, and 3 789 tonnes of ore from the Alma battery. Based on survey and sampling programme in 1983 a minimum 37 710 tonnes...

Since discovery in 1889, 16 390.64 tonnes of ore have yielded 620 829.67 grams of gold bullion, during several periods of operation. Ore has been treated at Peterborough Battery, on site, at Wallaroo smelting Works, and interstate. Small amounts of...

An intensive search for a large low grade silver lead zinc deposit was unsuccessful, although widespread low grade mineralization is present. Associated gold values over 26 metre interval at Eukaby Hill are too low grade to support large scale...

28 auger holes and 14 trenches delineated a minimum of 37 710 tonnes of 2.71 g/t gold at Alma and Victoria and a minimum of 1080 tonnes of 1.94 g/t gold at Alma Extended. Tailings also contain an average of 2 g/t silver. Cyanidation tests show that...

2 889.7 tonnes of ore treated and 61 693.58 grams of gold bullion recovered. Detailed statistics include locality and mine name of each parcel of ore.

An indicated 29 100 tonnes of tailings containing 1.88 g/t Au, 2 g/t Ag, 70 ppm Cu, 1200 ppm Pb, 350 ppm Zn, and 80 ppm As in 2 separate dumps remain on site. Cyanidation leach tests show that about 60% of Au in the truck dumps and up to 50% of the Au...

8 fully cored diamond holes tested possible fold structures near old mines, for Telfer type stratabound gold mineralization in shoots similar to those mined in the Alma and Victoria mines. 5 distinctive auriferous reefs were intersected in each...

Discovered in 1886, Westward Ho mine has a recorded production of 3 765.5 tonnes which yielded 34 729.48 grams of gold bullion. 4 000 tonnes were treated at a stamp battery at the mine and tailings were later cyanided. Remaining on site is an...
