Pierina
The Pierina mine is located in the Andean Cordillera in the Department of Ancash in north-central Peru, approximately 10 kilometres northwest of the city of Huaraz, at an altitude of approximately 4,100 metres.
Pierina is an open-pit, truck-and-loader operation. Ore is crushed and transported through an overland conveyor to the leach pad area. Run-of-mine ore is trucked directly to a classic valley-fill type of leach pad.
In 2009, Pierina produced 271,000 ounces of gold at total cash costs of $400 per ounce1. Proven and probable mineral reserves as of December 31, 2009 are estimated at 648,000 ounces of gold2. The mine life at Pierina has been extended to mid-2013.
