The San Ramon Mine is an epithermal underground silver mine located five kilometers southeast of the Guadalupe Production Centre which has been a significant contributor to production since 2008 from multiple zones. In early 2014 grades dropped with depth, and production decreased. During 2014, underground drilling from the bottom levels of the mine discovered new high grade silver zones in the nearby San Ramon Deeps Zone and mining of this area was carried out between 2014 and 2021. In 2021, surface drilling discovered the San Ramon Southeast Zone which is currently being mined. Additional drilling is planned to expand this zone as well as explore for other nearby zones of mineralization in this prolific area.
