In 2008, the mine contributed 3% to the company's annual production and employs in excess of 1,000 people. The Cerro Vanguardia mine consists of a number of small open pits.
History
The gold deposit at Cerro Vanguardia was first discovered in 1976 and, in 1987, mining group Pérez Companc S.A. formed a mineral exploration joint venture with AMSA, Anglo American’s South American holding company.
AngloGold, predecessor of AngloGold Ashanti, acquired a 46.23% interest in the project in 1998–99, and an additional 46.25%, the Pérez Companc stake, in July 2002, doubling its interest to 92.5%. AngloGold Ashanti owns the right to exploit the deposit for 40 years based on the Usufruct Agreement, signed in December 1996. Cerro Vanguardia, which was constructed at a total cost of US$ 270 million, was commissioned in late 1998.
The mine suffered a difficult year in 2008, when production fell by 25% while the cash cost more than doubled. The company did however manage to improve production in 2009 and lower the cash cost again. In 2009, the mine was also fatality-free for the seventh consecutive year.
Future mining plans at Cerro Vanguardia include an underground operation, from 2010, and a heap leach operation.
