The Kalgoorlie operation consists primarily of the Super Pit open-pit mine, located along the Golden Mile ore bodies which were previously mined from underground. The mine is located adjacent to the town of Kalgoorlie approximately 550 kilometers east of Perth, Western Australia. Barrick holds a 50% interest with Newmont Mining Corporation holding the remaining 50% interest.
Kalgoorlie is an open-pit, truck-and-loader operation. 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 also processed at the Fimiston mill. Concentrates that cannot be processed by the roaster is treated by two ultra-fine grinding mills.
In the first nine months of 2013, Barrick's share of production was 236,000 ounces of gold at all-in sustaining costs of $941 per ounce1. Barrick's share of proven and probable mineral reserves as at December 31, 2012, was 4.2 million ounces of gold2.
