Turquoise Ridge
The Turquoise Ridge property is located in the Potosi Mining District, about 70 kilometres northeast of Winnemucca, Nevada, on the eastern flank of the Osgood Mountains. Barrick is the operator and 75% owner of the mine with Newmont owning the remaining 25%.
Turquoise Ridge uses underhand cut-and-fill mining methods. Ore is transported to Newmont’s Twin Creeks mill for processing. The refractory gold ore is treated by pressure oxidation technology and gold is recovered using conventional carbon-in-leach technology.
In 2010, the Company’s 75% share of Turquoise Ridge’s production totaled 124,000 ounces of gold at total cash costs of $622 per ounce1. Barrick’s share of proven and probable mineral reserves as of December 31, 2010 was 4.2 million ounces of gold2.
