EXHIBIT C -Mining Plan (a) Mining dates Mining will commence upon completion of the entire permitting process, which is anticipated on or before August 30, 2002. Mining, crushing/processing, stockpiling and most reclamation activities should be completed within 50 days (prior to the start of the winter season). The primary reason for the development of the aggregate deposit located within the proposed permit azea is to provide roadbase gravel and subgrade fill material for existing and planned roads on the ranch property. It is estimated that a total of 100,000 tons of various grade material will be produced. The mining, processing and stockpiling operations at the proposed permit area will be completed during a single mobilization to the site. Approximately 40% of the material (40,000 tons) will be stockpiled outside the proposed permit boundary (to the west) on the adjacent Mask Ranch LLC. property. The remaining material will be made available for local commercial use and will be stockpiled within the proposed permit area as shown on the Exhibit E -Mining Plan Map. The material stockpiles to be located inside the proposed permit area approximately 60,000 tons) are planned to be reduced within 12 to 18 months and the area seeded and reclaimed. (b) Topsoil -soil suitable as a plant growth medium Topsoil is limited. Less than 15% of the proposed area of operations is currently vegetated and the existing topsoil is thin and has a high per cent of gravel and rock/cobbles. However, since the planned pit area of approximately 5 acres will be reclaimed as a pond, sufficient topsoil will be available so that all disturbed areas will have a[ least 6 inches of cover. Additional topsoil may also be imported from other areas of the Mask Ranch if necessary. The topsoil material will be stripped from the excavation area, salvaged and stockpiled along the pit perimeters (at the top of the slope) where the shore line for the pond will be located. Topsoil will also be stripped from azeas where the material stockpiles will be located so that it will not become contaminated with the processed and screened material. This topsoil from the proposed stockpile area will be placed to the southwest of the material stockpile and reserved for placement in reclamation. If topsoil stockpiles are to be left for more than 1 growing season, they will be seeded with the same recommended seed mix used for the site reclamation. These stockpiles will be located out of mine traffic areas and temporary stockpile and material handling locations. The reclamation of the majority of the disturbed areas will be done as soon as possible. (c) Thickness of overburden or quantity of waste rock. Overburden is minimal and is sufficient quality to be used in base course and fill material. All material below the topsoil horizon will be mined, processed and stockpiled. There will be no stockpiles of waste rock or overburden. (d) Thickness of deposit to be mined. Test pits indicate that the aggregate deposit has an average thickness of 8 [012 feet of material above the basement Mancos Shale throughout. The entire planned mine pit area will be excavated processed and stockpiled during a single crusher mobilization to the site. (e) Major components of the mining operation. I . Access to the site will be off Archuleta Counry Road 119 using the owners' private road and bridge. This access will be utilized for the duration of the mining activities.
