over the original tailings. Under that will be virgin pay gravels that can be washed and <br /> placed over the old tailings. This will create an empty ditch for processing the next <br /> block.Any growth media(soil) encountered will be placed temporarily on the upper <br /> limits of the mine block(north side)until the concurrent reclamation can be started. <br /> This material will be stockpiled and the seeded with the recommended seed mix for <br /> stabilization.A berm will be developed around the stockpile to control erosion until <br /> the grass seed germinates. <br /> Mining equipment will consist of a mobile washplant assembly, a pump, hoses and <br /> and a backhoe. There will be no buildings or permanent structures. The existing two <br /> track will be used for access with a new segment developed near where a ford will be <br /> established to cross the creek to enter the mine site. With the exception of washed <br /> gravel put into the soft spots on the road, no major improvements are planned. <br /> To prepare a block for mining, a pit/pond will be prepared to capture ground water for <br /> processing (Figure 2). The pond area will be (as marked), in an"L" shape about 40 <br /> feet wide and 300 feet long and 8 ft deep. It will hold 718,176 gallons of water(.27 <br /> acres). The wash plant will pump about 576 gallons per minute and return the same <br /> amount to the pond minus evaporation which will be about 300 gallons per month <br /> depending on conditions plus an additional amount of 10% lost by spray nozzels <br /> inside the trommel. Besides the volume of the water, the pond will act as a settling <br /> basin for fine silts and clays in the system initially. However, as the wash plant moves <br /> away from the pond the washed gravels will act as a filter capturing the silts and clays <br /> in the void spaces and on the surfaces of the rock particles. Ultimately it will create <br /> the conditions that somewhat existed prior to the original mining. <br /> Water will be purchased from HASP. <br /> Each mine panel will consist of a washed trench and a strip pile. When the first panel <br /> is completed the wash plant will be returned to the pond to start the next cycle. At the <br /> end of the second panel, the surface of the processed material will be contoured and <br /> the growth media will be moved there to prepare for final reclamation including <br /> revegetation. <br /> There are 5 potential panels in this proposed mine plan. The last one has not been <br /> mined and will provide a fair amount of growth media to augment the reclamation of <br /> the rest of the mine area. The total planned disturbance by mining will be about 8.4 <br /> acres, .57 acres of access road (assuming 10 feet wide), and .5 acres of percolation <br /> area for stormwater runoff. The percolation zone will be isolated in the existing <br /> previously mined trench on site and described in the storm water run off zone.As it <br /> exists,the site is self isolating from fugitive water. <br /> Storm Water Plan <br /> At the upper end of the pond, (farthest from the existing drainage) the pond will <br /> allow extra precipitation to escape the pond and infiltrate into the groundwater <br /> system through the gravel piles in 72 hours. <br />
