EXHIBIT C <br />JAMACO PIT <br />MINING PLAN <br />A tracked dozer or front -end loader working from east to west will push the sand <br />and gravel being mined in this operation into stockpiles. A front -end loader will then load <br />the material from the stockpile into haul trucks. Some of the sand and gravel could <br />remain in the stockpile for several weeks. The sand and gravel will be utilized in the <br />maintenance and construction of county roads in District 2 of Lincoln County. It is <br />anticipated that mining would start in March of 2011 and continue intermittently until the <br />year 2021 or 2026 depending on the amount of material in the pit. <br />Prior to removal of the sand and gravel 3 to 6 inches of topsoil will be stockpiled <br />for later use in the reclamation of the affected lands. These topsoil stockpiles will be hand <br />seeded if necessary to stabilize the piles and prevent erosion. The 1 to 2 feet of <br />overburden that underlies the topsoil will either be used as binder or stockpiled for later <br />use in the reclamation. These stockpiles will also be hand seeded as required for <br />stabilization and to prevent erosion. The maximum size area that will be mined at one <br />time would be from 5 to 6 acres; some reclamation will take place concurrently with the <br />mining operations in order to keep the affected area at the 5 to 6 acre size. Judging from <br />the amount of material available this pit should be in operation for about 10 to 15 years. <br />The pit will be active but will be used fewer than 180 days per year. No water will be <br />used to produce the sand and gravel being mined nor will any chemicals or explosives be <br />used in this operation. <br />The ranch road will be smoothed by the county using a motor grader. It will not <br />be elevated but will be bladed to approximately twenty (20) feet wide to provide easier <br />access to the site. A haul road into the pit will be also put in by the county road and <br />bridge forces. The haul road enters the pit from the north side of the boundary. This haul <br />road will also be approximately twenty (20) feet wide. Since these roads are not <br />considered to be permanent typical Lincoln County specifications will not be used. <br />Lincoln County utilizes somewhat modified Colorado Department of Transportation <br />Specifications when constructing permanent county roads. <br />The floor or bottom of the pit will slope gradually one to five (1 to 5) percent up <br />to the east until it is necessary to put in the final finished slopes that would go up to the <br />pit boundaries. The final slopes will be 4:1 or flatter. <br />The over burden to be removed is a mix of soil and sand and gravel that gets <br />sandier with increasing depth. The sand and gravel to be mined varies in thickness from 7 <br />to 12 feet. The material that under lays the sand and gravel is a mix of clay and sand that <br />turns to clay a greater depth. <br />3 <br />
