RECLAMATION COST ESTIMATE <br />EXHIBIT L <br />The worst case reclamation scenario will occur when mining is to begin in Phase 1 C, and all of <br />Phase I is to be backfilled. It is the largest backfilling action in the life of the mine. Later <br />stages of the operation take better advantage of concurrent reclamation to reduce the amount of <br />earthmoving needed to achieve the post mine land use. The components of the worst case <br />reclamation scenario are as follows: <br />1. Backfill and grade Phase IA to the final contour <br />a. 236,192 CY of backfill placed via loader, haul truck, and dozer from stockpile in <br />Phase 1 C. <br />b. Rip all 5 acres to a depth of 12 inches <br />2. Backfill and grade Phase 113 to final contour <br />a. 138,904 CY of backfill placed via loader, haul truck, and dozer from stockpile in <br />Phase 1 C. <br />b. Rip all 3.8 acres to a depth of 12 inches. <br />3. Place topsoil across all disturbed areas to be revegetated <br />a. Phase I = 8,067 CY <br />b. Phase 1 B = 6,131 CY <br />c. Phase 1C = 15,327 CY <br />4. Remove scale and office trailer. <br />5. Seed all retopsoiled areas <br />a. Mining phases = 18.3 acres <br />b. Berms = 4.3 acres <br />c. Office and scale area = 0.5 acres <br />6. Mulch are seeded areas <br />Based on the operator's previous reclamation efforts in the area of this sight, Table L -1 — <br />Reclamation Cost Estimate has a cost estimate for the cost of reclaiming the worst case scenario. <br />Cerise Mine March 2015 L -1 <br />
