The Kalgoorlie operations consist primarily of the Super Pit open-pit mine, which is located along the Golden Mile ore bodies previously mined from underground. The large open-pit mine is located adjacent to the town of Kalgoorlie approximately 550 kilometres east of Perth, Western Australia. Barrick holds a 50% stake in the Kalgoorlie operations; Newmont Mining Corporation holds the remaining 50% interest.
Mining at the Super Pit is by open-pit, truck-and-loader mining methods. Ore is treated at the Fimiston mill, with the resulting sulphide concentrates then roasted and leached at the Gidji roaster, located approximately 20 kilometres north of the main Kalgoorlie operations. Gold-laden carbon from the Gidji roaster is sent to the Fimiston mill for processing. Processing is supplemented by two ultra-fine grinding mills, which treat concentrate that cannot be processed by the roaster.
In 2008, Barrick's share of production was about 303,000 ounces of gold at total cash costs of $614 per ounce1. The Company’s share of proven and probable mineral reserves as of December 31, 2008 is estimated at 4.4 million ounces of gold2.
