The Burbanks Gold Mine is a gold mine located 9 km south east of Coolgardie, Western Australia.

It is currently owned by Barra Resources Limited.

History

Gold mines in the Kalgoorlie region

The Burbanks deposit historically produced over 400,000 ounces of gold from both underground and open pit mining.[1] Small scale mining still continued in the late 1990s.[2] From 1887 to 1914, the mine was the highest grade gold mine in Western Australia with 22.7 grams of gold per tonne. It was mined by WMC Resources in the early 1950s but closed down in 1991.[3]

Barra acquired the mine in September 2000 from WMC[4] and mined the deposit in an underground operation, developing a decline from the already existing Lady Robinson pit from July 2006. After mining 24,900 ounces of gold, Barra stopped the operation in August 2007,[5] allowing it to pursue an exploration campaign.[6] In late 2007, Barra believed to have made one of the most spectacular gold discoveries in Australian resources history, hitting an intersection yielding a very high 10,300 grams of gold per tonne,[3] at 350 metres below surface, in a vicinity where no drilling had been carried out before.[7]

In June 2009, Burbanks recommenced gold production in a mining and profit-share arrangement between Barra and Mulgabbie Mining Pty Ltd.[8] Ore will be treated at the Burbanks production facility of Ramelius Resources, which the company usually utilises for its own Wattle Dam Gold Mine.[9]
