<br />E7{13IBIT B - MINING PLAN <br />Ellison Mine - Pioneer Uravan, Inc. <br />November 13, 1978 <br />Ore will be mined underground by modified room and pillar methods used <br />by most underground uranium and vanadium mining operators in Western Colorado <br />and Eastern Utah. The rock will be broken into manageable sized pieces, loaded <br />into diesel underground trucks, trucked to the surface, and transferred into <br />larger trucks to be hauled to the mill. Whenever possible, all barren rock will <br />be left underground and used as backfill. <br />Total area disturbed at this site is 9.0 acres. Two vent holes are expected <br />to be needed at this mine. Vent hole locations are not known at this time. <br />Approximately 1/10 of an acre will be needed for each venthole and this acreage <br />has been added to the disturbed area. <br />Mining operations will cease when all existing ore is mined estimating 25 <br />years, at which time reclamation will be initiated. <br />
