The material volumes described in Table D -1 are approximate but are based on limited drilling <br />and test pits that were dug on site. Note that the areas above are located in the mining area. The <br />anticipated total disturbed area for the mining area portion of the operation consists of 190.63 <br />acres, which includes the sediment ponds. The additional disturbance comes from the access <br />road, topsoil stockpile, and the office / shop area. This is 11.82 acres for the access road and <br />residential protection berm, 3.96 acres for the topsoil stockpile and 3.69 acres for the office and <br />shop area. Therefore, the total disturbed area is 210.1 acres over the life of the mine. The <br />disturbance at any one time is much smaller since there will be ongoing reclamation as the pit <br />advances. <br />Topsoil will be stripped prior to mining each year. Overburden will be removed at the same time <br />as the topsoil but will be handled separately. Topsoil will be stockpiled or directly replaced <br />depending on the portion of the area being mined. Overburden will be placed on the pit floor and <br />not stockpiled. Details of the topsoil handling are shown in Table D -2 and also in Exhibit E - <br />Reclamation Plan. Gravel will be directly loaded into the crusher by a loader or will be hauled to <br />the crusher from the mining face in a truck. <br />Highway trucks will haul sellable material to market from the processing site. Truck traffic will <br />descend on the access road to the junction of T Road where it crosses the Montrose West Canal. <br />2. Mining Timetable <br />The following table (Table D -2) is a best estimate of the sequence of operations for the life of <br />the mine and is based on producing 104,000 raw tons per year and selling 100,000 tons per year. <br />Uncompahgre Pit, February 2013 D -3 <br />
