III IIIIIIIIIIIIIIII ERHIBIT "B" <br />PfINING PLAN <br />PSountain Shadows pit will continue to primarily be used by CCDC <br />as a source of road material in the development. This is an excellent <br />deposit with only 1' - 3' of overburden and a 20' - 30' seam of <br />aggregate. This pit was designated as "Commercially Extractable" in <br />the Front Range mapping under H.B. 1529. <br />As shown on the Mining Plan and Timetable, excavation will start at <br />the southeast corner and proceed west. This area was stripped earlier <br />by the previous operator. Overburden from the 1981 and 1982 phase will <br />~. be stockpiled to the north and then replaced on the 1980, 1981 and 1982 <br />phase when excavation is complete. The overburden from the remaining <br />segments will probably be stockpiled in the 1981 segment and then re- <br />placed on backslopes as excavation progresses. <br />Stripping will be done with dozer and scraper. Excavation will be with <br />front end loaders transporting to the crusher. Stockpiled material from <br />the crusher will be loaded into trucks for delivery as required on roads <br />within the development. <br />The Company presently excavates something less than 1'--; Acres per year, <br />and affected land will be used for less than 180 days per year (34-32 <br />103(6) II. Less than 70,000 tpy of combined overburden and mineral will <br />be removed from the site annually. The proposed timetable of excavation <br />is an approximation based on a best estimate of development and other <br />demands. <br />~• <br />
