EXHIBIT L RECLAMATION COST ESTIMATE (revised 9/25/19) The following Reclamation Cost estimate is based on the assumption that there will be no more than 25 . 00 acres ± distur- bance at any-one time . Of this, 4 . 92 acres are in the dry wash and needs no resoiling. Two areas need resoiling with 6 to 9 inches average of 7 inches deep, of salvaged soil : the 2 . 15 acres in the blow sand borrow area and the 2 . 35 acres in the terrace deposit area (111 permit area) (4 . 50 acres @ 7" 4235 yds) . The remaining 15 . 58 acres in the dry wash, of that approximately 400 or 6 . 23 acres wil31 need minor grading and seeding. The remaining 9 . 35 acres is area has adequate vegetation due to self reclama- tion. The mine working face will be limited to 1000 feet long by 15 feet high and be reclaimed using a cut/fill grading method. Four hundred (400) feet is in the blow sand area and 600 feet is along the channel bank that has been mined. Since the site is mostly within a dry wash there is no topsoil available from that area. The 11 . 15 acres (9, 000 cyd. ) disturbed in the dry wash would be smoothed using a D6T dozer and then seeded. At that time we will have to do 1, 560 cy of cut\fill sloping (1 . 56 cyd/lft) . A D6T is used for calculation purposes to do the shaping and grading in this calculation and the mobilization haul distance is 5 . 00 miles . The revegetation cost figure used includes grass seed, weed control and drilling costs . ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: Unit Cost 1.
