See Exhibit F for reclamation details. <br />~~ ldining Timetable <br />At the present time, annual production is being increased at <br />a reasonably regular rate. The following timetable is based on the <br />best projected estimate of future demand. Any economic variation <br />from the current norm could, and probably will, radically change <br />all of the timetable estimates. <br />Mining Timetable <br />Stage Years Mined Acres Total Acres <br />0 7.78 13.23 <br />I Part 1 4- 6 4.29 8.22 <br />I Part 1 5.53 7.61 <br />II Part 1 7.50 10.68 <br />II Part 2 4- 6 5.33 11.23 <br />II Part 3 4.11 7.94 <br />III 4- 6 10.90 12.46 <br />IV 4- 6 10.96 13.98 <br />V 4- 6 10.92 14.14 <br />VI 4- 6 10.74 17.05 <br />A 8-12 4.60 6.40 <br />Area 1* 7 ? 3.87 <br />Area 2* ? 7 10.65 <br />Area 3* 7 7 4.30 <br />30** 141.76 <br />i * It is unlikely that these areas contain c1~5•; but if <br />so, they will be mined as 1 to 3 additional stages <br />and reclaimed in the same manner as the rest of the stages. <br />** Estimated life of the mine is 30 years. <br />- 14 - <br />
