The post - mining land use planned for the Revenue Mine is wildlife habitat. To facilitate that land <br />use all disturbed areas will have 12 inches of topsoil placed on them prior to revegetation. <br />The soil will be stripped as required for mine activities at the time when it is needed. As much as <br />possible, topsoil will be directly placed on final waste pile surfaces as they are constructed. If <br />topsoil needs to be stockpiled on site, it will be placed in one of two designated areas. The first area <br />is immediately uphill of Sediment Pond 1. This topsoil stockpile area will be used while the <br />Revenue waste pile is being built. Once the Revenue waste pile is full, an area on the top of the <br />Revenue waste pile will be used to store topsoil if needed. A significant amount of topsoil will be <br />imported over the life of the mine to satisfy the reclamation requirement of 12 inches over the <br />reclaimed areas. These calculations are described in detail in Exhibit E. Any topsoil that is imported <br />will be suitable as a growth medium and will not be contaminated in any way. Any party bringing <br />topsoil to the site will be required to sign a form stating that the soil is free of any contaminants that <br />could negatively affect the environment. These forms will be kept on file at the mine site. <br />2.1 Atlas Waste Pile Topsoil <br />The topsoil to be stripped from the Atlas waste pile area currently underlies roughly three feet of <br />old tailings. These tailings have been tested for metal content, and show sufficient silver values to <br />justify processing. It is anticipated, however, that over the long period that the tailings have been in <br />this location, some of the metal sulfides may have leached down into the immediately underlying <br />topsoil. Since the topsoil depth in this area has been determined to be about 18 inches on the <br />average, the top six inches can be treated as tailings, and not saved for reclamation while still <br />leaving sufficient topsoil to cap the Atlas waste pile area. <br />2.2 Shaft Area Soils <br />The shaft areas consist almost exclusively of rock outcrop and rubble complexes. These areas will <br />be excavated from underground, so surface soils that are disturbed due to the shaft construction will <br />be kept in the immediate vicinity for use in reclamation. <br />Revenue Mine August 2012 I - <br />
