Operating Mines

Arcata | Peru

The Arcata site is located in the Department of Arequipa in southern Peru, approximately 300 kilometres from the city of Arequipa, at an altitude of 4,600 metres above sea level.

The mine is conformed by vein systems where the epithermal vein deposits are of an intermediate sulphidation type with predominant silver values and variable quantities of gold and base metals. The veins are mined by conventional and mechanized (trackless) cut-and-fill breast or overhand stoping methods utilising timber support.

The unit operates an underground mine and a concentrator for the production of silver concentrate with gold content. The concentrator produces silver/gold bulk concentrate by flotation with a current capacity to treat 1,750 thousand tonnes per day. In 2008, Arcata produced 20,639 tonnes of concentrate with 9 million ounces of silver and 24 thousand ounces of gold.

Ares I Peru

The Ares site is situated 4,900 metres above sea level in the Andes Mountains, approximately 275 kilometres from the city of Arequipa, in southern Peru. The unit operates an underground mine and a processing plant.

The underground mine is conformed by vein systems where the epithermal vein deposits represent gold and silver mineralisation of intermediate and low sulphidation type. The veins are mined by conventional and mechanized (trackless) cut-and-fill breast stoping methods utilising both rockbolts and timber as support.

The processing plant has a current ore production capacity of 940 thousand tonnes per day. In 2008, Ares produced 1.5 million ounces of silver and 64.2 thousand ounces of gold.
