About Mariana Resources

Mariana Resources Ltd is an AIM quoted exploration and development company with an extensive portfolio of gold, silver and copper projects in Argentina and Chile. In Argentina, in addition to the Las Calandrias gold-silver discovery project, the Company owns the Sierra Blanca silver prospect and has a joint venture with Hochschild Mining. Mariana also owns exclusive exploration rights to a 160,000 Ha area. All of these projects are located in the Deseado Massif gold district in mining-friendly Santa Cruz province of southern Argentina, which hosts four gold/silver mines and several notable bonanza type precious metal prospects.

In Chile, Mariana has a joint venture agreement with US based international mining and natural resources company Cliffs Natural Resources Inc., to explore for Iron Oxide-Copper-Gold deposits ('IOCG') in a 92,000 km² area ('SCM Mariana Area') in north-central Chile. The SCM Mariana Area includes two Iron Oxide Copper Gold ('IOCG') exploration projects in the highly prospective Atacama Fault Zone, approximately 100 km from Freeport's Candelaria Copper Mine: the 44km² Buenaventura and 46km² Perro Chico projects.
