<br /> <br />EXHIBIT C <br />6.3.3 <br />MINING PLAN <br />AVALANCHE CREEK MARBLE & ALABASTER LLC <br />WHITE BANKS MINE <br />6.3.3(1)(a) Estimated Dates Mining Will Commence and Eod <br />Mining has commenced and will continue under the terms of Colorado Division of Minerals and <br />Geology Office ofMined Land Reclamation Permit No. M-91-95 until this application is approved. <br />The White Banks Mine is expected to have a 50 year life. Therefore operations will terminate in <br />2048. <br />6.3.3(1)(b) Topsoil Rerooval, Storage, and Protection <br />Topsoil up to 12 inches in thickness, where present, has been or will be removed from all areas that <br />have been or aze to be disturbed, including the mine portal face, the mine bench, the mine road (nor <br />including FDR 310) and lower yard azea, and main yazd area where alabaster blocks may be stored <br />(see Exhibit E). Topsoil will not be removed from those parts ofthe main materials storage yard area <br />where storage will be intermittent, and where most stored materials will be on pallets, racks, reels, <br />runners, wheels, tracks, or otherwise raised offthe ground, which will for the most part allow existing <br />vegetation to continue to grow. <br />Topsoil so removed will be stored in one of two locations as shown on Exhibit E. Slopes of Gfe-of- <br />mine (LOM) topsoil storage piles will be 2:1 or less. LOM topsoil piles will be roughly graded to <br />appear as natural as possible and seeded with a mixture approved by the U. S. Forest Service and the <br />Division in order to minimize erosion. <br />No redistribution of removed topsoil to disturbed areas prior to final reclamation is planned. <br />The LOM topsoil storage piles are located separately from other stockpiles, out of the way of mine <br />traffic, and out of stream channels and drainageways. <br />6.3.3(1)(c) Thickness of Overburden or Waste Rock <br />Approximately 10 ft ofsemi-weathered alabaster and subsoil overburden will be removed from the <br />portal face for a horizontal distance of 75 ft and a vertical distance of 30 ft, for a total of 833 cubic <br />yards. This material, less stored topsoil, will be used to expand the existing portal bench, which is <br />too small to safely operate existing as well as proposed mining equipment. The expanded and portal <br />face excavation and mine bench fill are shown of Exhibit E. <br />~~ <br />.ir my 19.199911] ~IPMI <br />
