MINING PLAN EXHIBIT D (CONT) <br />floor to reduce the haul distances when reclamation starts. See <br />the MINING PLAN MAP - EXHIBIT C -1, for the approximate location of areas <br />discussed in this text. <br />This mine will be operated year- around, weather permitting, <br />as a specification aggregate supply for Tamrock Gravel's use and <br />for sale on the open market. The plan is to crush material and <br />remove the stockpiles as needed, which means that in some years <br />the mine may be closed for as many as 120 days due to inclement <br />weather. There may also be long periods when there are no <br />activities at the mine due to a reduced market demand for the <br />material. <br />The Shot Rock Pit will be a dry mine, except the water used <br />for dust control during processing and on roads. Dewatering of <br />the pit will not be needed as no groundwater will be exposed. <br />The material will be mined using front -end loaders, dozers, track <br />hoes and haul trucks. Screening, crushing and stockpiling will <br />occur on site when the mine is in full operation. Production <br />from the Shot Rock Pit will begin in 2012 and continue for 15 to <br />20 years, depending on demand for the products in the market <br />area. <br />Mining equipment may include but is not limited to, front - <br />end loaders, scrapers, motor graders, bulldozers, track -hoes, <br />drills, tractor trailers, tandem -axle end dumps, articulated haul <br />trucks, and water trucks for dust control. Processing and <br />supporting equipment to be found on site may include but is not <br />limited to portable screening plants, generator sets, portable <br />crushers, and portable conveyors. <br />MINING PLAN <br />This mine will produce specification aggregates, crunched <br />rock, rip -rap, ballast, sand and crusher fines, et al. Most all <br />of this material will be sold but it is estimated that approxi- <br />mately 3% of the total rock removed will be crusher fines for <br />which there is no market. These fines will be spread over the <br />mine floor during reclamation to make the root zone over the <br />underlying shale. <br />The setback around the mine boundary will vary from 15 to <br />110 feet depending on the slope of the ridge. Our plan is to <br />day - light -out the sides of the mine, except along the north line <br />where the hard rock slope will be left nearly vertical and the <br />6 <br />
