EXHIBIT "A" 49b -(IA <br />MINIi•G PLAN <br />The Mining Plan and Timetable Map (Exhibit "C") portrays the sequence <br />of excavation as projected based on estimated deiand.The timeframes <br />could vary depending on the business climate, but the sequential <br />design appears to be the best method of extraction. <br />Excavation will be handled by scrapers and front end loaders. The <br />material will transported for processing and stockpiling by either <br />scrapers or field conveyors to the 1980-81 segment north of the Ana <br />Branch. Tup;;oil will be stockpiled on various high points inside the <br />perimeters of the pit area for replacement in reclamation. Overburden <br />will be used to build a combination haul road and flood protection <br />berm around the perimeter of the affected area as well as for backslnpe <br />material. The flodd protection berm and haul road will also protect <br />stockpiled topsoil as well as the pit area from flooding. Backsloping <br />in the excavated area will follow extraction and be an ongoing part <br />of the operation. Topsoil will then be replaced at 8 to 12" to the <br />waterline and be ready for reseeding. With this manner of operation, <br />reclamation will be about one year behind extraction. <br />The Company plans to operate this project on a 50 acre floating bond. <br />Disturbance areas are estimated as follows: <br />a. Major - stripping and excavation; 30 acres <br />b. Moderate - backsloping and topsoil replacement; <br />10 acres <br />c. Minor - final grading and reseeding; 10 acres <br />The end product will be a series of six tree lined lakes with gently <br />curving shorelines. Lake size will vary from 8 to 50 acres. <br />WestWater Engineering APPENDIX C - 48 July 2012 <br />
