The San Bartolomé mine, located on the flanks of Cerro Rico Mountain near Potosi, Bolivia, is one of the largest pure silver mines in the world and the second largest silver mine in Bolivia. Cerro Rico, a prominent mountain in the region, stands at over 15,400 feet (over 4,700 meters). The mine has brought economic development, a strong commitment to environmental stewardship and worker safety to the community. Mining at San Bartolomé is conducted using simple, free-digging surface mining techniques that do not require drilling or blasting, which results in minimal impact to the landscape.
The San Bartolomé silver mine and associated milling operation, is operated by Empresa Minera Manquiri SA (“Manquiri”), a wholly-owned subsidiary of the Company. Access to the property and processing facilities is by paved and all-weather gravel roads leading south-southwest from Potosí. The Bolivian national mining company, Corporación Minera de Bolivia (“COMIBOL”), is the underlying owner of all of the mining rights relating to the San Bartolomé mine, which are leased to Manquiri.
