Arcata I 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 tonnes per day. In 2009, Arcata produced 22,352 tonnes of concentrate with 9.5 million ounces of silver and 28.6 thousand ounces of gold.
