Overview and locality
Cerro Vanguardia, in which AngloGold Ashanti has a 92.5% stake, is the Company’s sole operation in Argentina. Fomicruz, a state company, owns the remaining 7.5%. Cerro Vanguardia is a gold-silver operation with multiple open pit and underground mines located within the property that are mined simultaneously.
Cerro Vanguardia operates a single tailings dam. The state road GO-337 passes close to the operation, providing access for logistics. Power for the mine is supplied and purchased in the open market. Three mining methods are used for underground mining: sub-level stoping (bottom-up and top-down), cut and fill, and room and pillar.
A brief history
- Gold exploration at the site was started in late 1980s by the state owned Fomicruz and Minera Mincorp (JV between Anglo American Argentina Holdings Limited and a local private company, Perez Companc).
- Cerro Vanguardia began as an open pit operation in 1998 and this was supplemented in 2010 with the start of shallow underground mining to access high-grade mined material.
- To complement the already existing gold plant, a heap leaching operation was started in 2012.
- The mine has been operated by AngloGold Ashanti since 1998.
