Surface Facilities List <br />a. Waste rock storage pile <br />b. Ore stockpile <br />c. Soil excavation and stockpile areas <br />d. Surface drainage control structures <br />e. Fuel and oil storage areas <br />f. Shop /dry and maintenance shops <br />g. Roads and associated pads <br />h. Utilities <br />i. Ventilations shafts <br />a. Waste Rock Storage Pile <br />The previously reclaimed waste rock area, mining facilities and portal are located <br />in a small valley that drains from the north to the south. A small drainage <br />separates the waste rock pile, located on the western side of the drainage, from the <br />mine portal. The previously reclaimed waste rock pile was built against the <br />hillside with the toe of the waste rock pile extending toward the road on the south <br />and west side, and sloped along the drainage on the eastern side toward the portal. <br />It is anticipated that much of the waste rock that will be generated during future <br />mining efforts can be gobbed into depleted underground stopes. Additional waste <br />rock will be placed on the existing surface pile and against the south facing hill <br />sloping up to the access road that runs along the permit boundary. (see Exhibit C - <br />Maps, Figure C2 "reclaimed waste dump "). <br />The LP -21 waste storage area is the same "design" as most other waste storage <br />areas in the Uravan Mineral Belt. Carts of mucked rock are arranged in small <br />closely spaced piles within the area outlined as affected acreage (Exhibit C - <br />Maps), flattened and compacted, and the process repeated as the storage area <br />increases. <br />b. Ore Stockpile <br />The ore stockpile is located southeast of the waste rock pile. During active <br />mining the ore is piled up to a workable stockpile and hauled to the mill using a <br />first in, first out system. Ore will be stored onsite for no more than 30 days after <br />mining operations cease. <br />The ore is not expected to have any adverse leaching effect for the following <br />reasons: limited time on the pad, limited precipitation in the area, low <br />permeability and limited downward mobility due to the high clay content of the <br />soils underlying the pad. <br />A contractor will be used to haul the ore from the surface ore stockpile area to the <br />mill. The ore haulage contractor will be responsible for a spill control plan. <br />
