once it has been mined to its approximate depth of roughly 100 feet (elevation 6190'). Ground <br />water is expected to be near 105 feet, but the operator commits to staying two feet above ground <br />water. In the event it is encountered, exposed ground water will be buried with at least two feet <br />of material. Processing facilities and stockpiles will remain at that location in Phase 1B & 1C for <br />the remainder of the mine's life. Phase 1 C will then be mined to match the Phase 1 A and 1 B <br />floor elevation of 6190'. See Mining Map 2. <br />Phase 2, 3, and 4 will be mined in benches to the final floor elevation of 6190' (see Mining Maps <br />4 -6 in The Site Plan). As mining progresses through the site, reclamation will be conducted <br />behind the mining. The backfilling of Phase IA is an example of this. The northern highwalls of <br />the pit (north side of Phases 1 B, 1 C, & 2) will be backfilled to the final reclaimed slopes of <br />3H:1 V. This reclamation will conducted concurrently with mining, to minimize the ongoing <br />disturbed area. Due to overburden quantity limits, the east and south side of the mining area will <br />be mined to 3H:1 V, and as such will only require topsoiling and seeding for reclamation. See <br />Mining Maps 4 -6, the Reclamation Map, and Cross Sections. <br />2. Mining Timetable <br />Mining operations at the Cerise Mine will take roughly 18 years, based on an annual production <br />of 375,000 to 500,000 tons per year (437,000 tons per year average). This is an estimate, and the <br />life of the mine will vary based on market conditions. <br />Cerise Mine March 2015 D -2 <br />
