All building will be removed at the end of mine life. Most of these will be shipping containers, <br />and therefore will only need to be hauled off site. <br />6. Worst Case Reclamation Costs <br />The worst case reclamation scenario will be early in the mine life when the sediment pond has <br />been constructed, and the topsoil has been stripped from Stage 1 of the waste rock landform. <br />Table D-2 shows a breakdown of each reclamation cost for this scenario. The list below <br />discusses the reclamation steps in detail: <br />• Grading out Stage 1 of the WRL into final condition (<100' dozer push). 300' x 800'= <br />8888 CY @ $0.75/CY = $6667 <br />• Grading sediment pond and pad to final condition (loader haul of 200 feet): 2000 CY @ <br />$1.50/CY = $3000 <br />• Spreading 12 inches of topsoil over Stage 1, the graded sediment pond area, and the <br />Usable Pad Area (loader haul of 200 feet). 2.36 ac x 12 inches / 27 CF/CY = 3,807 CY. <br />3,807 CY @ $1.50/CY = $5,711 <br />• Backfilling portal (8' x 10') 40 feet deep via haul truck (1600 foot haul). 119 CY @ <br />$5.00/CY = $593 <br />• Backfilling secondary escapeway portal (6' x 8' portal) 40 feet deep via haul truck (1800 <br />foot haul). 71 CY @ $5.00/CY = $355 <br />• Seed topsoiled areas. 2.36 ac @ $300/ac = $708 <br />• Disk topsoiled area. 2.36 ac @ $150/ac = $354 <br />• Mulch all seeded area. 2.36 ac @ $500/ac = $1180 <br />• Haul all sea cans off site. Three sea cans @ $1000 per sea can= $3000 <br />Including a 28% DRMS cost inflator, the total worst case reclamation cost is $27,153. <br />Detroit City Mine February 2017 D-3 <br />
