Colorado Inactive Mine Reclamation Program CLOSEOUT REPORT MAINTENANCE PROJECTS OSM Number—466 Severance Tax — FMS8 Maintenance Project Name —Alaska Basin Maintenance and Forfeiture Project rORIGINAL MINESITE INFORMATION Project Number: Feature Numbers: 38, 39, 40, 41a, Feature Types — stopes, shafts, PKA-10-1160 & 41 b, and mine waste piles REASON MAINTENANCE NEEDED—After two previous projects, the Maid of the Mist 2004 Project and the Alaska Basin 2006 Project, maintenance and completion of mine closures was needed. Both of the previous projects encountered problems due to early snow and early winter shut-downs. In 2006, the Alaska Basin contractor attempted to close mine opening 38, but found the site to be significantly larger after the adit collapsed and opened into a stope. Mine openings 41a and 41b also needed additional backfill because of settling, most likely from the two on-site school buses buried in the stopes. The 2009 project also addressed post 1977 mining activity at the number 40 shaft, and the number 39 waste piles located in an active stream channel. BIDDING/CONSTRUCTION INFORMATION Type of Bid: Documented Quote Bid as part of the Alaska Basin Maintenance and Forfeiture Project, PKA-10-1160 PO Number: Contractor Name & Address Construction Dates Cost OE PKA-10-14 K and P Property Designs Start $11,680.00 236 South 3rd#219 8/20/09 PO Date: Montrose, CO 81401 End 8/13/09 9/21/09 Construction Work Description —Alaska Basin Maintenance and Forfeiture construction started in late August 2009 and proceeded into mid-September 2009. Site 40 was changed from a grate to backfill during construction because the site's conditions were more suitable to backfill due to unconsolidated bedrock and mine waste at the site's surface. Site 40 should be monitored for settling of the backfill. Snow remained on site 38 well into late August and 38 had to be shoveled As of 05/14/09
