It is believed that approximately 4 inches of topsoil was removed from the site and stored on the boundaries of the site as shown on Exhibit C-1 (Mining Plan Map). This material will be replaced during reclamation. All removed topsoil will be seeded as necessary to protect from erosion if it remains in place for more than 180 days. Any necessary seeding will utilize the seed mix below. Topsoil stockpiles will be stored in places and configurations to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized. Once stockpiled, the topsoil shall be rehandled as little as possible until replacement on the regraded slopes and floor of the disturbed area. As this site is presently under a mining and reclamation permit, some topsoil/growth medium has already been removed and placed in stockpiles as shown on the mining plan map. As most of the site is currently disturbed it is not anticipated that additional topsoil will be available for salvage, however,topsoil and/or growth medium from any currently undisturbed areas that could be affected as a result of this mining or reclamation plan will be properly salvaged and stockpiled for use during future reclamation. This salvaged material will be placed in strategic positions around the perimeter of the pit so as to be out of the way of any mining activities and readily available for use in reclamation.

As the rate specified in the table above applies to drill seeding, Applicant will double the rate should the broadcast seeding,method be used. (c) Thickness of overburden: There is little to no overburden available at this site as the mining target has been fully opened for extraction. However, through the processing of the mined material, it is anticipated that some amount of unmarketable fines will be generated during the crushing and screening process. These fines will be placed over the re-graded rock slopes and used as a sub-base prior to re- applying topsoil and/or growth medium. It is anticipated that there will be enough of this material available for placement of 4-6 inches on the re-graded slopes and pit floor. (d) Thickness of deposit to be mined: The Applicant currently estimates that the deposit to be mined may be approximately 25-40 feet thick.
