MINING PLAN EXHIBIT D (CONT) <br />will prevent any damage to said wall. By leaving 90 feet instead <br />of L5 feet the safety factor is increased by nearly 6000. The <br />discussion contained in the Geotechnical Stability Exhibit <br />explains why mining will have no impact on the slurry wall. <br />The setback lines on the rLLap are the indication of the <br />mining limits, i.e., the top of the slope into the mining area. <br />When the setbacks will no longer be disturbed they will be <br />reclaimed as prescribed in the reclamation plan. <br />During mining all interior pit slopes will be maintained <br />with a pit-ward attitude so that there will be no drainage off <br />the affected land. This same slope management plan will prevent <br />any offsite slides or other disruptions, and will also address <br />some of the storm-water runoff questions arising from the Clean <br />Water Act. No water will be discharged from the pit and all <br />stormwater will be collected on the site as required. <br />We have adequate water available to meet the requirements <br />for evaporative loss during initial mine startup, see EXHIBITG. <br />An application will be made for a well permit to address the need <br />for evaporative losses associated with mining in the ground water <br />( table. This will only be needed until reclamation is complete as <br />the entire area will be backfilled so no lake area will be left. <br />MINING TIMETABLE <br />The continuing uncertainty of economic conditions in the <br />construction materials industry precludes an accurate forecast of <br />demand during the life of the mine. This estimated mining <br />timetable is based on an average year and it is expected that a <br />specific year will vary widely from the average. <br />MINING TIMETABLE <br /> <br />MINING AR ACRES AVERAGE ANNUAL <br />EA YEARS <br />TOTAL AREA ` <br />MINED AREA PRODUCTION <br />TONS/YEAR <br />Priola Pit 1-3 13.68 10.96 250,000 <br />Totals 13.68 10.96
