    Description

    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.

    Realmo Value Estimation

    Realmo estimates a property’s market value using a proprietary methodology that incorporates public data and user-submitted information. This cumulative value is generated by integrating a variety of conventional and innovative methods. 

    Disclaimer

    These figures are not official appraisals and should not be used as a substitute for a valuation performed by a licensed appraiser.

    Actual market value may differ due to factors not captured in the data. Estimates are offered for informational purposes only, and users should conduct independent research before making financial or investment decisions.

    By using this feature, you acknowledge that Realmo is not responsible for actions taken based on these estimates.

    AI approach

    Realmo AI Method estimates property value using machine learning models trained on millions of comparable listings, transactions, and market signals. It analyzes property features, location intelligence data, and current market dynamics to predict the most probable market value in real time.

    Cap approach

    Capitalization Method calculates value based on estimated net operating income (NOI) and applying a market-based capitalization rate (cap rate), we estimate what a typical investor might be willing to pay for it.

    Comparable approach

    Comparable estimate is based on recent sales of similar nearby properties, adjusted for factors like size, condition, and location.

    Relative

    Relative property class coefficient uses factors that account for typical price differences between various asset types (e.g., retail vs. industrial) to provide a more accurate market-aligned estimate.

    Geo

    Comparable Sales Method, enhanced by Geo coefficients — location-based adjustment factors that reflect differences in price levels across neighborhoods, cities, or regions ensuring a more accurate, market-sensitive valuation.

    Alternative use

    Estimate considers the property’s potential value if used for a different purpose-based on zoning, demand, and market feasibility.
