About this file
This is an Inactive Mine Site Field Form document from the Colorado Division of Reclamation, Mining, and Safety, detailing the Brasscap Project (Project #7684, OSM Project #561) in San Juan County, Colorado. The project involves the reclamation and closure of five inactive mine features located in the Poughkeepsie area near the Handies Peak quadrangle, dated September 6, 2012, with one feature surveyed on August 30, 2012. The identified features include two adits and one shaft on BLM-managed land (IDs 29-30) and two additional adits on USFS-managed land (IDs 32-34). Access to these sites requires navigation via Highway 550 through extremely rough 4WD terrain, with features located between 10,581 and 12,228 feet in elevation. All sites present significant accessibility challenges, including marsh and bog crossings, steep slopes, and rocky terrain that preclude standard equipment access.
The work specifications require hand-labor-only closure methods tailored to each feature's condition and characteristics. Preferred closure methods include cable netting or grating for double-stack openings (ID 29), bulkhead construction for deeper rectangular adits (ID 30), and backfill with existing waste rock combined with grate or bulkhead installation for shafts and adits on USFS land (IDs 32-34). Mine dump volumes range from 30 to 400 cubic yards per site. All five features contain potential bat habitat, necessitating design considerations such as bat access provisions in closure structures. The project emphasizes minimal disturbance to existing conditions through hand-work methodology and utilization of on-site waste rock materials, with closure method flexibility permitted to accommodate contractor expertise and site-specific conditions.
