Kanowna
Barrick has a strong presence in the Eastern Goldfields near Kalgoorlie-Boulder, 570 kilometres east of Perth in Western Australia. In addition to the Kalgoorlie Super Pit, there are currently three underground mines in production — Kanowna Belle, Raleigh, and Bullant, collectively “Kanowna”. Kanowna Belle and Raleigh mines are mined by longhole stoping and underhand longhole bench stoping with paste fill methods. Additionally, geotechnical driven mining sequence and a fill system is employed to minimize the impact of mining induced stress on the underground operations. Bullant utilizes retreat sublevel stoping as its mining method. Ore types in this region consist of both refractory and free milling, which are processed at the Kanowna Belle mill.
During 2009, Kanowna produced approximately 284,000 ounces of gold at a cash cost of $532 per ounce1. Proven and probable mineral reserves as of December 31, 2009 are estimated at 1.23 million ounces of gold2.
