EXHIBIT L <br /> RECLAMATION COSTS (Revised 8/10/2021) <br /> The following Reclamation Cost estimate is based on the <br /> assumption that the maximum bonded disturbance will be no more <br /> than 35 . 0 acres ± at any-one time. This is based on the current <br /> operation activities at the mine and for the foreseeable future, <br /> as shown on the Bond Map. <br /> The mine working face volume for the cut/fill sloped is 6. 9 <br /> yd/lft on a length of 1, 000 feet long, an average of 25 feet <br /> high. The partial slope area (2 : 1 to 3 : 1 sloping cut/fill) <br /> volume is 2 . 9 cy/lft on 1, 000 feet long, an average of 25 feet <br /> high. The 35 acres will then be resoiled with an average of 3 <br /> inches of soil using a scraper to distribute the soil and a motor <br /> grader to spread and shape the seed bed. <br /> At that time approximately 13, 270 cubic yards of topsoil <br /> will be respread on the disturbed area; 6, 900 cy of cut\fill <br /> sloping will be needed on the working face and to complete final <br /> cut/fill sloping and final grading of the partially shaping <br /> slopes will require moving 2, 900 cubic yards of material. Table <br /> L-1 shows the various areas of disturbance at the time explained <br /> above and the associated cost to reclaim the 35 acres . <br /> IN this estimate a D8N dozer is used to do all cut/fill <br /> sloping, a 631G scraper will respread the soil and a 140G Blade <br /> is used to shape the reclamation area. The mobilization haul <br /> distance is 12 . 0 miles at a average speed of 45 mph. The <br /> revegetation cost figure used includes fertilizer, grass seed, <br /> labor and drilling costs. The following table shows the unit <br /> cost data used on Table L-1 Bond Estimate. <br /> ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br /> Unit Cost <br /> 1 .
