Red Mesa Pit <br />MINING PLAN <br />The following is the general scope of the mining plan that will be implemented at <br />Skanska's Red Mesa Pit. Please reference the attached maps of the area of interest to <br />follow the mining and reclamation plan(s). The Pit was originally developed under a 111 <br />project specific permit, the depleted area has been topsoiled, seeded and is establishing <br />vegetation and will be included within the active permitted area. <br />New mining will begin in the northwest portion of the pit where reserves were not <br />previously mined. The crusher assembly will be positioned to the east of the active <br />mining area and stockpiles will be to the south of the crusher (see active mining map). <br />Prior to development of a new mining area the site will be stripped of all conservable <br />topsoil and overburden to be used for reclamation purposes. Gravel will be excavated <br />and feed into the crusher assembly by tracked dozer, or a tracked excavator and loaded in <br />to the feeder with a wheeled loader. Depending on the aggregate end product needed the <br />crusher assembly used will vary. Typically a belt feeder going into a jaw/screen will <br />handle the primary crushing, with roller cones and screens completing the tertiary <br />crushing and classifying. Processed material is then stockpiled using a series of <br />conveyors and stackers. <br />Mining would take place in a planned sequence from west to east until the reserves are <br />mined to the extent allowable by the crusher configuration. Upon this occurrence, <br />regrading of the mined area will take place in order to create a new staging area for <br />material processing and stockpiling.
