The San Juan Ridge Mine property consists of approximately 1,700 acres of patented land located in Nevada County, CA. The property was first mined during the CA Gold Rush as an open pit hydraulic mine. This method was used until the Sawyer Decision of 1886 prohibited any further unrestricted use. The San Juan Ridge deposit was last mined in the early to mid 1990's as an underground room and pillar operation.
San Juan Mining Corporation desires to reopen the San Juan Ridge Mine and resume mining activities while utilizing current advancements in technology, equipment, and computer modeling to reduce environmental impacts, promote a safe working atmosphere and increase the efficiency of the operation.
