Waste Rockpiles and Process Materials <br />Waste rock materials primarily composed of carbonaceous rock type is currently placed <br />along the lower staging azea, immediately south of the lower working pit/face area. This <br />waste rock dump will continue to receive no grade/low grade materials for several yeazs <br />into the future, slowly expanding in size to the south of existing mine operations. During <br />highwall development work over the next several yeazs, waste rock of siliceous mineral <br />content may also be hauled to this location. It is estimated that a 1:1, W:O stripping ratio <br />will be needed over the next several yeazs to continue to have white trtazble rock <br />available for mining. This will mean that up to 30000 tons per year may be hauled to the <br />lower waste dump over the next several years. New affected land boundaries will allow <br />for waste dump development well to the south of the existing dump face. However, <br />fixture hangingwall development may require a lift or iwo (20'-30' height) of waste <br />placement above the current lower staging azea. As mining proceeds north following the <br />mazble bed, the hangingwall waste rockpile will also proceed from south to north along <br />the eastern side of the mazble contact. The hangingwall waste rockpile wi111ike1y have <br />breaks in the south facing outslope to facilitate roadways and drainage of the toe of the <br />waste pile along its eastern aspect to direct all surface flow from the rockpiles and <br />roadway into the Iower pit area. Since the drainage azeas in question will be Limited to <br />that area immediately east of the mazble working face (all drainage within the working <br />face of the marble bed and highwall azeas to the immediate west of the mazble bed will <br />drain into the lower pit azea), drainage will simply follow the roadway system as a ditch <br />structure along both sides of the access road from the bottom staging azea to the top <br />mining/stockpile level. <br />Production/Process Stockpiles <br />For the next several field seasons, the lower staging area will serve as the main location <br />for product stockpiling and crushing/screening operations. The azea is graded to drain <br />into the lower pit azea and is lazge enough to facilitate a 5000 ton topsoil stockpile and up <br />to 20000 tons of product stockpiles. As mining progress to the north over time, process <br />areas and stockpiles will likely follow is the area immediately east of the working face as <br />waste rockpile lifts aze leveled for mobile crusher, screening, and stockpile location. <br />Stacking conveyors may be used to move fmish rock material off of the limited space of <br />the upper bench azeas and down to the lower staging azea where more storage space is <br />available. <br />Roadways within Affected Land Boundaries <br />County Road 228 enters the affected land on the southern end of the property and <br />traverses the affected Land in the southern third and central portion of the affected land <br />azea. This roadway will be maintained for public access at all times. Where the roadway <br />crosses Taylor Gulch, arip-rapped jeep trail crossing of the drainage will be maintained <br />to allow for 4WD vehicle access across the drainage channel. The crossing will have <br />8 <br />
