Oracle Ridge Mine is an underground copper mine located on private property on Marble Peak in the Santa Catalina Mountains. The mine was first established in the late 19th century, and the mine operated on and off until 1996, when it closed due to the fall of copper prices. The proposed mine restart is in the permitting and design detail stage for resuming operations.[ more... ]
The mine portal entrances are located on the north side of Marble Mountain. The primary access to the mine will be from the existing Black Hills Mine Road (FR 4450), which is located about three miles west of San Manuel. The Black Hills Mine Road was used by the former operation as its main access.
