|1892||exploration by Arthur Bayley and William Ford at Coolgardie.|
|1893||the Irishmen Paddy Hannan and Tom Flanagan discovered gold at Kalgoorlie.|
|1929||Joe Thorn became general manager of the Lake View and imported new technologies.|
|1989||Kalgoorlie Consolidated Gold Mines Pty Ltd (KCGM) founded and the small mines of the area united.|
The gold ores of Kalgoorlie formed in a rock unit called the Golden Mile Dolerite. The ore occurs in shears, which are the result of ancient tectonic movements. More than 2,000 ore lodes occur in an area of 5km length and 1km width, to a depth of more than 1km. The ore lodes vary in size between a few centimetre to several hundred meters in length. To be of economic interest, they must be at least 10m long and 6m thick.
The ore is a combination of gold, pyrite, chalcopyrite, tellurides of gold, silver, mercury and lead. But gold is the economicaly most important component. The gold deportment is 30% native gold, 25% telluride gold, 45% gold inclusions in pyrite.
Since its discovery more than 50 million ounces of gold have been mined. At the moment the Super Pit produces up to 900,000 ounces of gold per year. It is the largest gold mine in Australia.

The Super Pit or Fimiston Open Pit is a huge opencast mine, big enough to be seen from space. This mine is operational and it is not possible to visit the mine. Huge trucks, the size of a house, transport tons of gold ore to the processing plant. The pit is built in steps, to make it stable.
Although the mine itself is not open to the public, it is possible to see the open pit from a lookout. Binoculars and tele lens for photographers are a good idea.
This huge operation was the idea of Alan Bond who tried to buy up all the leases in this area. Before this, the area called the Golden Mile was scattered all over with small companies running their own mines. KCGM manages the Super Pit for two owners, Newmont Australia Ltd and Barrick Gold of Australia Ltd.
