RECLAMATION COSTS • <br />HENDERSON MINE <br />February 1993 <br />Many affected areas are being revegetated, but are not considered totall~~ reclaimed. <br />Estimated costs and concomitant financial warranty for such areas are adjusted <br />downward as reclamation occurs and upward to cover additional disturbed areas. <br />Because of the continuously changing acreage and status of affected land, the Board <br />stipulated that reclamation costs be updated every two years in conjunction with submittal <br />of the annual report and map. We have refined our acreage estimates, our methods, and <br />our costs. The estimated costs (in 1992 dollars) of reclaiming all anticipated disturbances <br />through 1994 is $6.276 million. <br />A. SITE TYPE CALCULATIONS <br />1.
