This is the mining permit area for the he Jacobina mine complex which consists of several underground gold mines and a 6,500 tonnes per day carbon-in-pulp processing plant.

Mineral Reserves and Mineral Resources for gold as at Dec. 31, 2013 were 2.2 million oz. proven & probable + 2.6 million oz. measured & indicated, with a strategic mine life forecasted for 13 years.

The property is comprised of 5,996 ha of mining concessions, a mining claim covering 650 ha, and 113,546 ha of exploration permits and claims, all owned by Yamana through its wholly owned subsidiary JMC. The exploration concessions are renewable on a three year basis and have annual fees ranging from $1.00 to $1.55 per hectare.

The Jacobina Mine Complex uses both selective and non-selective mining methods in the form of Cut and Fill (CAF) mining for the shallow dipping zones and Sublevel Longhole Stoping (SLS) for the zones with dips that allow for bulk type mining. Access to the mineralized zones is by ramp. The Jacobina Group hosts four different major types of gold deposits: conglomerate-hosted; quartzite, andalusite schist and metaconglomerate-hosted; ultramafic-hosted; and mafic/intermediate dike-hosted.
