J <br />Siloam Stone - Bedrock #1 Mine Permit # M-1997-086 <br />RECLAMATION COST ANALYSIS - July 7, 2009 <br />This reclamation cost estimate in based on the assumption that <br />there will be no more that 60.00 acres ± disturbed at any one time. <br />Of this sixty acres 25.00 ac. would be slab rock area and 35.00 ac. <br />would be temporary stone storage area (TSSA). It also assumes, that <br />when it comes time to resoil the SLAB rock area that only 12 inches of <br />soil would be spread over the disturbed area and that the TSSA will <br />only need raking and seeding. The remaining overburden piles would be <br />graded and seeded. At that time we will have to respread 24,200 cubic <br />yards of topsoil. We estimate that at a worst case scenario that <br />there will be a maximum of 2,050 L-FT needing cut/fill sloping and <br />1025 L-ft of backfill would be needed. Using the numbers shown on the <br />typical cross section on page 17 or the 1997 application book and <br />assuming that since sloping and resoiling would run concurrent with <br />mining approximately 40% of the dirt work would be done. The table <br />below outlines the various areas of disturbance at that time. In this <br />estimate a D-8N dozer will be used to do the shaping, a 988H loader is <br />used to redistribute the topsoil and 140G motor grader will be used to <br />spread the soil and prep the seed bed. The revegetation cost figure <br />for the slab rock area includes fertilizer, grass seed, mulch and <br />drilling costs. The revegetation cost for the TSSA only covers <br />raking, fertilizer and seed. The unit cost numbers come directly for <br />the Divisions CICRES cost estimate prepared by Ms. Deb Zack on 11- <br />April-2008, except the Loader and Motor grader costs. <br /> STAGE TOTAL SOIL DEPTH <br /> NEEDS RESOILING 15.O0 12" <br /> REVEGETATION SLAs AREA 25.00 <br /> REVEGETATION TSSA 35.00 <br /> SLOPE CUT/FILL 2050 LINEAR FEET <br /> SLOPE ROCK FILL 1025 LINEAR FEET <br /> RESOIL @ 1 2" 24,200 CUBIC YARDS <br /> ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br /> Unit Cost <br />1.
