About this file
This is a work list and feature inventory document for the DRUM West Calamity Outlaw Project in Colorado, detailing mine opening closure and remediation work across multiple mine sites. The project encompasses the closure and stabilization of 60+ mine features, including adits, prospect adits, shafts, and subsidence features distributed across numerous named mine locations such as Radium 7, Blue Ribbon, Lee Group, Little Maverick, Sunflower, and Small Spot. The work involves various closure methods including polyurethane foam backfill, steel grates with bat ladders, corrugated steel pipe installation, cable net systems, bulkheads, and simple backfill with native rock and waste rock. Each feature is cataloged with specific dimensions (excavated, eroded, and present sizes), depth measurements, and UTM coordinates for precise geographic location. Access descriptions are provided for each mine site, ranging from highway access with vehicle travel to remote locations requiring helicopter transport or extensive hiking.
The closure specifications reference Standard Work Specifications (SWS) sections and standardized drawings for construction guidance, with particular attention to bat exclusion and habitat protection requirements noted for several locations. Notable features include varying polyurethane foam requirements ranging from 1/3 cubic yard to 4 cubic yards per opening, with some sites requiring archaeologist monitoring during construction. Several sites present specific constraints such as limited equipment access, steep terrain, downed vegetation removal, or prior maintenance issues requiring remediation. Access routes are consistently documented starting from Highway 141 north of Gateway, Colorado, with detailed turn-by-turn directions to individual mine clusters. The project appears to be a comprehensive remediation effort focused on environmental stabilization and public safety while accommodating bat habitat protection requirements.
