Operation: Ciénega
| > Underground gold mine, in operation since 1992 |
|
|
Ciénega is located near the small community of Nuestra Señora de la Ciénega, population 2,700. The nearest town of Santiago Papasquiaro, population 45,000 (2010 census), is 153 kilometres away, which itself is 172 kilometres from Durango, the capital of the state. Because the community is entirely dependent on the mine, community engagement efforts include access to basic services. |

| > What we plan to do in 2012 |
|
|
• Comission the San Ramon satellite; ore will be trucked and processed at Ciénega
• Ongoing dilution control
• Evaluate opportunities to increase silver and gold recovery rates by leaching zinc concentrates
• Obtain International Cyanide Management Code certification; which was delayed in 2011 due to the
expansion
• Continue exploration of the Cebollitas cluster; which is also expected to be a satellite of Ciénega |
