Contemporaneous reclamation will commence when 200 to 400 linear feet is <br /> mined to the final mine depth of 6050 ft. elevation. A 3H:1V 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:1V slope. <br /> Surface mining will occur as an open pit. Topsoil in the stockpile and <br /> processing area does not need to be removed but may be pushed aside in order to <br /> level the area, making more surface available for operating and stockpiling. This <br /> topsoil will form a perimeter berm that will serve as a visual barrier. Should topsoil <br /> or other suitable plant growth material be encountered elsewhere, it will be placed <br /> on the reconstructed 3H:1V slope. In the event excess topsoil or other suitable plant <br /> growth material is encountered, it will be stockpiled and the stockpiled stabilized by <br /> seeding with the reclamation seed mix. <br /> Mining equipment includes an excavator, a grizzly, off-road trucks, a loader <br /> and a bulldozer. A motor grader and a water truck will be used to maintain roads <br /> and mitigate dust. The material is initially screened with a grizzly. Further <br /> processing, if necessary, is performed through a third party contractor. <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 /> Access Roads <br /> The historic access onto Hwy 93 has served the mine many decades. With <br /> infrequent mine campaigns and low production volumes, the historic access will <br /> continue to be used by the applicant. In addition, the applicant is proposing an <br /> additional and optional access north to West 561h Avenue to be developed in the <br /> event CDOT's plans for Hwy 93 improvements result in access restrictions. <br />
