MANAGEMENT RECEIVED OCT 12001 Mr. Joseph Dudash Division of Minerals and Geology 1313 Sherman Street, Room 215 Denver. CO 80203 Dear Mr. Dudash: Division of Minerals 8 Geolony Re: Bowie Resources Limited Bowie No 2 Mine PR-06 -Reclamation Estimate Permit No. C-96-083 On Behalf of Bowie Resources Limited, we aze submitting comments concerning [he Division's estimate of reclamation costs as revised for PR-06. We have identified the following items for evaluation: Compaction (Task 1171 The division offers a rationale that, because backfilling time exceeds compaction time, $141,666 should be added to reclamation costs because of idle time associated with the compaction machine. Bowie agrees that some additional expense is involved with this idle compaction machine, but should not be charged for operational costs or operator costs during this idle time. The division uses $119.69 x 1,183.61 hours = $141,666.28, Bowie Suggests that the calculation should be $48.44 x 1,183.61 hours = $57,334.06, a difference of $84,332.22. 2. Nuclear Densi Testing_of Backfill (Task 1161 Bowie does not agree that "the technician is required to be on site for all of the backfilling." Bowie azgues that it is not the backfilling that is tested, rather the compaction of the backfill that is required. Furthermore, it is not the function of the technician to ensure the compaction, but to provide evidence of the compaction of the backfill material, and therefore the technician is not required to be present for all compaction time. Bowie suggests that a more appropriate calculation for Nucleaz Density Testing would be based on a percentage of compaction time (say 50%) times an hourly rate (the Division's estimate of $69.30), rather than the total backfilling time x an hourly rate. This method results in 441.45 hours x $69.30 = $30,592, a reduction of $112,617.
