About this file
This document is a Colorado Division of Reclamation, Mining, and Safety Inactive Mine Site Field Form for the Brasscap Project, documenting four separate mine features requiring closure within the Poughkeepsie Gulch area of San Juan County, Colorado. The project encompasses closure work on four inactive mine sites: the White Crow claim (shaft feature), Port Hope claim (adit feature), Michigan Girl claim (adit feature), and Picket claim (adit feature), all located in the Handies Peak quadrant at elevations ranging from 10,675 to 12,211 feet. Access to all sites requires four-wheel-drive vehicles via Engineer Pass or Hurricane Pass, with notably challenging terrain and limited equipment accessibility at most locations. The work descriptions specify various closure methods including backfill, bat grates with concrete footers, drain pipes, corrugated steel pipes with access structures, and bat ladders tailored to each site's conditions. Mine dump volumes range from 150 to 750 cubic yards across the sites, with combined estimated impacts requiring specialized remediation. Work is constrained by environmental factors including marsh and bog crossings, slight seepage conditions, and significant water drainage from certain features requiring hand work only at some locations.
The field forms indicate that bat habitat considerations are present at three of the four sites, necessitating specialized closure methods that accommodate wildlife while securing the mine openings. Equipment access is limited or unavailable at three sites, requiring hand labor and manual installation methods for most closure structures. Project management was conducted by CJL with inspections completed on September 6, 2012. Land ownership involves multiple entities including the U.S. Forest Service (Poughkeepsie sites) and Bureau of Land Management (Picket claim), with one site under Standard Metals ownership (Michigan Girl). Adjacent land use is designated for USFS and BLM recreation and wildlife purposes. No specific pricing, contract term, award date, or bidding timeline information is provided in the field forms.
