TRAPPER MINING zNC. <br />1^ 1 ~ <br />~~ ~~ v ~ ~~ ~Tn' ~~~. <br />November 30, 2006 v~4 <br />ivision w Rec~a#~§@tIt <br />Ms. Janet Binns ~ Mining and ~~k?!~ ; <br />Environmental Protection Specialist <br />Colorado Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Deaz Ms. Binns: <br />Re: Trapper Mining Inc:; Permit No. C-81-010, Minor Revision MR 21.1 Revise <br />Topsoil Stripping Area in D Pit, I Seam Area; Reroute-a Portion;of a VVest;Panel <br />Powerline <br />Please find enclosed duplicate copies of permit revision MR-211. Trapper is making <br />minor modifications to topsoil strip azeas in the north end ofD pit (add 7.4 acres). This D <br />pit azea has been permitted for extraction of an isolated area of I seam, Trapper is seeking <br />approval to re-disturb a small azea that has previously been released from bond. This <br />change is shown on attached Map M10B, Sheet 1. In addition to the added topsoil <br />stripping, Trapper is also seeking approval to reroute a portion of the powerline that nuns <br />through this D pit, I seam reserve azea. This powerline feeds an F pit substation. The <br />reroute corridor will cross an azea that has been released from bond. While disturbance <br />will be minimal, the corridor (4,375 long, 15 feet wide) will need to be permitted. This <br />change is shown on Map M13, Sheets 1 and 2. <br />These changes affect the reclamation liability. A total of 7.4 acres of disturbance is being <br />added in D pit. At 14"of lay-down, 13,928 cubic yazds aze required. Using the most <br />recent bond calculation (DMG CIRCES software), the average wst per cubic yard is <br />$1.26 resulting in a total cost of replacement of $17,549. Bond revegetation costs average <br />$575.40 per acre (includes reseeding failed azeas). The cost of revegetation totals $4,258. <br />The addition of the powerline corridor adds an additional 1.51 acres of area that may <br />need to be revegetated. At $575.40 per acre the cost is $869. In summary, the liability <br />should increase as follows: <br />Topsoil replacement <br />Revegetation <br />Subtotal <br />Induect costs at 17.8% <br />$ 17,549 <br />5 127 <br />$ 22,676 <br />$ 4,036 <br />P.O.
