The Enterprise Mine was an underground gold and silver mining operation <br /> that operated both as a historic mine, beginning in 1899, and more recently as a mine permitted by the State of Colorado. <br /> Reclamation activities to satisfy the requirements of the bond were completed by Colorado Inactive Mine Program in 2009. <br /> The maintenance performed in 2010 was completed at the request of the USFS to address additional road reclamation, <br /> rate removal and barrier construction, site erosion, and supplemental seeding. <br /> Permit Information <br /> Permit Number: Operator Name: Mine Name: <br /> M-1983-068 Maurine M. Carpenter Enterprise Mine <br /> Type of Mine— 110 U/G Commodity Mined—Au, Ag <br /> PRE-RECLAMATION SITE CONDITIONS: <br /> The bond forfeiture reclamation work completed during 2009 consisted of safeguarding two (2) open mine entries, removal <br /> of an abandoned aluminum travel trailer and other debris from a historic site, construction of a French drain and the <br /> backfilling and grading of a large open cut at the lower entry, reclamation of three (3) miles of mine access roads, and the <br /> revegetation of approximately seven (7) acres of disturbed land. <br /> BIDDING/CONSTRUCTION INFORMATION: <br /> Type of Bid: (x) Documented Quote <br /> ( ) Formal Bid as the: Enterprise Maintenance Project, PKA-11-1192 <br /> PO Number: Contractor Name&Address: Construction Dates Bond Amount <br /> OE-PKA-11000000011 $N/A <br /> K&P Property Designs Start: August 24, 2010 (No bond money remained after <br /> 236 South 3rd, #219 completing reclamation work in <br /> Montrose, CO 81401 2009) <br /> PO Date: End: September 3, 2010 Project Cost <br /> August 6, 2010 $ 41,798.52 <br /> (Includes$185.52 for seed costs & <br /> $1,783.00 for interpretive sign) <br /> Construction Work Description: <br /> Maintenance activities completed during the summer of 2010 included the removal of an access gate at the boundary of the <br /> Wilderness Area and the construction of a boulder barrier in its place; reclamation of an additional access road, <br /> approximately one-tenth (0.1) of a mile in length; hand work to repair soil erosion along the three (3) mile access road and at <br /> the lower mine entry; supplemental seeding to enhance vegetation in areas of marginal growth; construction of a trail within <br /> the footprint of the reclaimed access road to facilitate foot access into the Wilderness Area; construction of water bars along <br /> Tellurium Creek Road to mitigate erosion and sediment transport. <br /> A large component of the project work was located within the Collegiate Peaks Wilderness, a designated non-motorized <br /> area. In 2009 the USFS granted a thirty (30) day window to use motorized equipment to complete the planned reclamation <br /> This was not the case for the Enterprise Maintenance Project in 2010, and the work occurring within the Wilderness <br /> boundary required a sizable effort from crews using hand tools and pack animals to complete. <br /> The Notice to Proceed was issued on Monday, August 23rd and construction work began on August 24th with the removal of <br /> the Wilderness gate and construction of a boulder barrier in its place. An additional access road, approximately one-tenth <br /> (0.1) of a mile in length, was then reclaimed by intensive surface roughening—a method which employs an excavator to dig <br /> gouges, approximately eighteen inches (18") in depth by twenty-four inches (24") in width, in an alternating pattern along the <br /> entire length of the road. <br /> As of 05/14/09 <br />
