face. The stockpile and processing area locations will be consistent during the life of <br /> the mine. <br /> Based on market demand, the clay is hauled from the site to brick factories <br /> with annual hauling quantities ranging from 250 tons to 20,000 tons per year. The <br /> existing interior haul road and access will be used. No new roads will be <br /> constructed. The life of the mine is anticipated between 30 and 40 years. Two to ten <br /> employees will work the mine during mining operations. <br /> Mining is campaign style mining. This means that product is mined and <br /> stockpiled once every three to five years for a duration of three to five weeks per <br /> campaign. Outside of the mining campaign there will be limited activity at the mine. <br /> Most of the activity will consist of hauling the product stockpiles to the brick plant <br /> intermittently every two to six weeks. <br /> Contemporaneous reclamation will commence when 200 to 400 linear feet is <br /> mined to the final mine depth of 6050 ft. elevation. A 3H:IV slope will be maintained <br /> at the toe of the hogback face that blends with the reclaimed slope of the Flintlock <br /> Mine to the north. As sandstone and overburden are removed from the working <br /> face, it will be placed at the toe of the exposed mined out face to further build out <br /> the 3H:IV slope. <br /> The Golden Mine is a surface mine. Topsoil in the stockpile and processing <br /> area does not need to be removed but may be pushed aside in order to level the <br /> area, making more surface available for operating and stockpiling. This topsoil will <br /> form a perimeter berm that will serve as a visual barrier around the stockpile area. <br /> Should topsoil or other suitable plant growth material be encountered elsewhere, it <br /> will be placed on the reconstructed 3H:IV slope. In the event excess topsoil or other <br /> suitable plant growth material is encountered, it will be stockpiled and the stockpiled <br /> stabilized by seeding with the reclamation seed mix. <br /> Mining equipment that will be on site for three to five weeks every three to <br /> five years will include an excavator, a grizzly, off-road trucks, a loader and a <br /> bulldozer. This equipment will be seen mining at the toe of the hogback and building <br /> stockpiles behind the topsoil berm in the stockpile area. A motor grader and a water <br /> truck will be used to maintain roads and mitigate dust. The material is initially <br /> screened with a grizzly. Further processing, if necessary, is performed through a <br /> third party contractor. Outside the mining weeks, the loader will be parked near the <br /> stockpiles, out of site from passersby behind the topsoil berm. Trucks are loaded by <br /> the driver when material is hauled offsite. <br /> The mine floor slopes toward the toe of the hogback face. Surface water as <br /> precipitation and snow melt will pool at the base of the mine face and infiltrate within <br /> 72 hours. Perimeter berms are constructed along the edge of the mine floor and <br /> around the stockpile area. <br /> The CO State Land Board (SLB) commissioned a paleontological survey in the <br /> vicinity and including the permit area. In the even paleontological artifacts are <br /> discovered, mining will immediately cease in the area of the discovery and the SLB <br /> will be notified. <br /> Blasting OQgrations <br />
