Kalgoorlie JV

The Kalgoorlie operations consist primarily of the Super Pit open-pit mine, which is located along the Golden Mile orebodies previously mined from underground. It is Australia’s largest open-pit mine, located adjacent to the town of Kalgoorlie approximately 550 kilometers east of Perth, Western Australia. Barrick holds a 50% stake in the Kalgoorlie operations; Newmont Mining Corporation holds the remaining 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 kilometers 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 2007, Barrick's share of production was 304,000 ounces of gold at total cash costs of $488 per ounce¹. The company’s share of proven and probable mineral reserves as of December 31, 2007 is estimated at 4.6 million ounces of gold².

In 2008, Barrick’s share of production is expected to be 320,000 to 350,000 ounces of gold at cash costs of $545 to $575 per ounce¹.
