O£thc total, 10,000 <br />Icy would be pushed downhill with a production rate of 357 Icy/hr; and would take 28 hours. The <br />remaining 3,333 ley. of waste rock would be pushed uphill and away from the drainage, using a <br />production raft of 3251cy/hr., it would take 10 hours. The total project would take 38 hours of <br />dozer time at $100lhr. (53,800). <br />Task t14 GrAde pond, vents and shop areas and roads. <br />DMG's cost estimate is $2,594, based upon an estimated 3 acres to be gaded. <br />Ona the waste rock stock pile is contoured, the dump area will be graded on the final pass. <br />Therefore; the total acreage requiring grading will be 2.25 acres instead of 3. Cotter has <br />subtracted the difference from the total cost of task no. 4. <br />Ts'k M~ Replaco topsoil (waste rock fines) <br />The waste rock fines will be spread during the re-contouring efforts, a9 there is no segegation <br />between the fines and the waste rock material. <br />Teak #6 Re-vegetate 5.32 acres, <br />Cotter agees with this cost. <br />Task N7 Mobilization and Demobilization <br />DMG's cost estimate of 51,547.
