16270 California Mine Rd Drytown, CA 95699
This exceptional 193.85-acre industrial property in Amador County, California, presents a unique investment opportunity. The offering encompasses two key locations: a 133-acre active slate mine and a 60-acre processing plant. The mine, operating under a 1995-approved conditional use permit and reclamation plan, extracts rare Mariposa black slate. Estimated reserves stand at 4.7 million tons, with an annual extraction limit of 30,000 tons. The processing plant, situated at 2201 Michigan Bar Road in Ione, CA, benefits from Mineral Resource zoning, enabling 24/7 operation and unrestricted trucking for shipping fine-ground slate. Rail transport is also a possibility, though currently inactive. The plant's zoning allows for a wide range of processing and shipping options. In 2011, a non-conforming use was approved by the Amador County Planning Department. The mine's location is 16270 California Mine Rd, Drytown, CA 95699. The combined property includes APNs 008-140-023-000, a portion of 008-140-005-000, and 005-060-010-000. This offering presents a rare chance to acquire a fully operational slate mining and processing operation with significant reserves and flexible zoning.
