Table D-2 Simmons Pit Mining Sequence <br /> Production per Length of time to <br />Year ear tons phase Comments complete months <br /> 1 Site Preparation, Topsoil stripping, build stockpiles along the 2 <br />2009 - hi hwa . <br />2009- Mine in Mining Area 1, stockpile overburden and topsoil. Build the <br /> 120,000 2 isolation berm in the northern portion of the mining areas as shown 10.8 <br />2010 on Map C-2. Seed the stockpiles. <br /> Mine in Mining Area 2, stockpile topsoil and place the overburden <br />2010- encountered on the pit floor and sideslopes in Mining Area 1, where <br /> 120,000 3 available, to the elevation and slopes shown on Map F. All remaining 13.0 <br />2011 overburden encountered will be stockpiled. Seed the stockpiles. <br /> Bring the wash plant to the site and create the wash ponds. <br />2011- Mine in Mining Area 3, Stockpile topsoil, place the overburden <br /> 120,000 4 encountered on the pit floor and sideslopes to the elevation and 13.1 <br />2012 slopes shown on Map F. <br />2012- Mine in Mining Area 4, place the overburden encountered on the pit <br /> 120,000 5 floor and sideslopes to the elevation and slopes shown on Map F and 17.1 <br />2013 direct place topsoil in Mining Area 3. Seed the retopsoiled areas. <br />2013- Mine in Mining Area 5, place the overburden encountered on the pit <br /> 120,000 6 floor and sideslopes to the elevation and slopes shown on Map F and 16.7 <br />2015 direct place topsoil in Mining Area 4. Seed all retopsoiled areas. <br /> Mine in Mining Area 6, place the overburden encountered on the pit <br />2015- <br />120 <br />000 floor and sideslopes to the elevation and slopes shown on Map F and <br />20.6 <br />2016 , direct place topsoil in Mining Area 5. Reclaim the haul road within <br /> Mining Area 5 and seed the retopsoiled areas. <br /> Mine in Mining Area 7, place the overburden encountered on the pit <br />2016- 120 <br />000 8 floor and sideslopes to the elevation and slopes shown on Map F, <br />20.6 <br />2018 , direct place topsoil in Mining Area 6. Reclaim the haul road within <br /> Mining Area 4 and seed the retopsoiled areas. <br /> Mine in Mining Area 8, place the overburden encountered on the pit <br />2018- <br />120 <br />000 <br />9 floor and sideslopes to the elevation and slopes shown on Map F, 14.3 <br />2019 , direct place topsoil in Mining Area 7. Seed the retopsoiled areas. <br /> Reclaim the haul road in Mining Area 3 <br />2019- _ 10 Remove facilities, use the stockpiles to reclaim Mining Area land 8, 4 <br />2020 seed newly topsoiled areas. <br /> Total 132.1 <br />The mining schedule is planned to minimize disturbance by reclaiming areas as additional <br />mining is undertaken. This table is based on a reasonable projection of average production rates. <br />The table shows that mining and reclamation will occur approximately 11 years and the total <br />gravel mined will be approximately 1,260,000 tons. This is based on computer grids generated <br />from the topography and the available exploration data. <br />Simmons Pit, March 2009 D-3
