About this file
This document consists of Colorado Division of Reclamation, Mining, and Safety inactive mine site field forms for the Brasscap Project (OSM Project #561) located in San Juan County, Colorado. The forms document four separate mining features (IDs 11, 11a, 12, and 13) within the Poughkeepsie mining area accessed via Engineer Pass near Ouray. The project requires closure and remediation work on multiple mine openings: an adit requiring a bat grate with access (Feature 11), a partially collapsed stope requiring backfill with waste rock (Feature 11a), an adit requiring a bulkhead or grate with access (Feature 12), and an adit requiring a bat grate with access (Feature 13). All features are located on or near USFS land designated for recreation and wildlife use, with elevations ranging from 11,292 to 12,139 feet. Access to all sites requires four-wheel drive vehicles, and good equipment access is unavailable at all locations. The work descriptions specify contractor options for closure methods, including provisions for bat habitats (confirmed by USFS wildlife biologist Andrea Wong at Features 11, 11a, and 13), bat ladders, concrete footers, hatch access doors, and drain pipes.
The four features collectively have an estimated mine dump volume of 650 cubic yards across all sites. All features require access for closure work and present challenges due to terrain, equipment limitations, and wildlife considerations. The forms document baseline conditions dated September 6, 2012, with detailed measurements, GPS coordinates, and existing structural conditions (rock and timber linings, waste rock surficial materials, and standing water at Feature 12). No pricing information, funding sources, contract terms, bidding procedures, or award dates are specified in these field assessment forms, which serve as technical documentation for mine remediation planning and contractor bid preparation.
