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 2010, Pierina produced 191,000 ounces of gold at total cash costs of $424 per ounce1. Proven and probable mineral reserves as of December 31, 2010 was 791,000 ounces of gold2.
As a result of rising gold prices, Pierina’s mine life has been extended to the end of 2014.
