Section 1.0 General Description of Mining Activities <br />The site will have rock, sand and gravel mining, as well as gold placer mining. The primary material to <br />be mined over the life of the mine will be boulders. Placer activity may be more or less active in any <br />given year. For this mining, excavation of loose gravel will take place to bedrock, or to the limit <br />imposed by the mining slopes, or to 2 feet above ground water level, whichever is encountered first. The <br />maximum mining slopes are 2.5H1 V. The depth to bedrock is expected to be from 50 feet to 120 feet <br />from the surface. Any material that is excavated containing higher concentrations of gold will be <br />transported to the wash plant, where the majority of the gold will be recovered. The material will be <br />mined with loaders, track hoes and/or dozers, and the raw material will be hauled to the wash plant by <br />trucks or loaders, which is shown on Map C -2. Any material that is low in gold will be treated as <br />overburden and will be placed in the mined out area from the previous cut. The wash plant will consist <br />of a hopper, a trommel screen, a sluice, and another finer screen to wash out fines up to 100 mesh. Sand <br />and gravel washed from the sluice and screens may be delivered to stockpiles and sold as sand and <br />gravel products or may be used for backfilling as part of reclamation. <br />As shown on Map C -2, four mining areas are planned for the gold/gravel excavation activity: <br />Mining Areas 1, 2, 3 and 4. <br />Mining Sequence <br />The mining sequence will be as follows: <br />Mine Area 1 first, hauling all material to the wash plant located on the south side of the River. There is <br />an existing river crossing allowance from the US Army Corps of Engineers for the site but it will be <br />moved to the new location shown on Map C -2. As new areas are mined, backfilling and topsoil <br />replacement will occur on an ongoing basis. The total mining pit area not reclaimed or disturbed at any <br />one time is limited to 1.0 acres. The wash plant area and the water holding ponds add an additional 1.0 <br />acres. All existing roads will be left in place at the end of mining. After Area 1 is mined, all mining on <br />the north side of the River will be completed. <br />Sullivan Aggregate Pit March 2015 D -2 <br />
