EXHIBIT C <br />MINING PLAN <br />Mining will begin upon the issuance of the proper permit from the Division of Minerals <br />and Geology, estimated to be during March of 2012. The mine life is expected to be 30 <br />years with a projected completion date of December 15, 2042. A buffer zone of 10 feet <br />has been allowed on the west, north and east side of the 10.45 acres parcel that is owned <br />by Mr. Rominger. This area is not to be disturbed and is outside the limits of the pit <br />boundaries. An existing irrigation head ditch lateral is located along the northern <br />boundary. Adequate space will be provided to avoid disturbing this ditch and with two <br />adjacent pits that have excavated near the ditch, it will be easy to determine what that <br />distance might be. It is estimated that a minimum buffer will be 25 feet. An overhead <br />electric line crosses the north part of the site with one utility pole being located on the <br />site. Excavating in the vicinity of the utility pole will be coordinated with the San Luis <br />Valley Rural Electric Cooperative. It is anticipated that excavation will maintain a 10 foot <br />undisturbed radius around said pole. The domestic well near the south edge of the <br />property will remain undisturbed and is owned entirely by the land owner. <br />The topsoil will be stripped to a depth of approximately 12 inches and stockpiled. The <br />topsoil will initially be stockpiled in the northwest comer of the site as shown on the <br />attached Map E, or possibly on one of the other corners of the site. There is not expected <br />to be any overburden or waste rock requiring removal. Until mining begins, it cannot be <br />determined how much area will need to be stripped at any given time but is assumed not <br />to exceed 5 acres. The stockpiled topsoil will be sloped to 2:1 or flatter for the temporary <br />slopes on the edge of the pile and the entire topsoil stockpile seeded with the same seed <br />mixture and at the same rate as proposed by the NRCS for the final reclamation plan once <br />it has been determined that the stockpile will not be added to for a period of 1 year. Any <br />infestation of noxious weeds will be controlled by the pit operator, using approved <br />chemical methods of control and standard acceptable methods of application of such <br />chemicals or tillage, if appropriate. <br />The site will be mined to an estimated depth of 15 feet, with the bottom of the pit staying <br />a minimum of 2 feet above the elevation of the ground water on the site so that there will <br />not be any ground water exposed and also so that the recommended reseeding plant types <br />will thrive. The site will be rectangular shaped as shown on the Exhibit A -3 Survey, a <br />historic survey of the property filed in the Rio Grande County Surveyors Records as Map <br />No. 130. Mining will begin in the northern portion of the site and proceed in a southerly <br />direction. <br />The mining operation will use conventional construction/mining equipment such as front - <br />end loaders, dozers, trucks and track hoes. It is anticipated that a vertical or near vertical <br />face will be created and worked. At an offset distance from the boundary sufficient to <br />match the depth of the pit, the sides will then be mined on the 3:1 grade (or flatter) to <br />create the final exterior slopes as part of the mining process. For example, if the pit is 10 <br />feet deep when working near an exterior boundary, at a distance of 30 feet from said <br />
