EXHIBIT E SUNDAY MINE RECLAMATION PLAN - AS AMENDED The following section discusses amended areas to the existing Sunday Mine Permit (Permit Number M 1977-285, issued September 3Q, 1977 and amended May 23, 1983). This Reclamation (112) Permit Amendment is for five proposed vent holes located on various Sunday Mine claims. One vent hole is located in the southeast quarter of Section 23, two vent holes are located in the northeast quarter of Section 24, one vent hole is located on the section line between the northeast quarter of Section 24 and the northwest quarter of Section 19, and the fifth vent hole is located in the northwest quarter of Section 19. These five vent holes are anticipated to be installed between 2007 and 2010. The disturbed area anticipated for each vent hole will be approximately ~/a acre, for a total disturbance from the five proposed vent holes of 1.5 acres. Vent holes will be reclaimed by welding a steel plate over the vent hole casing and then constructing a reinforced concrete cap over the steel plate. The concrete cap will include small I- beams, angle iron, and rebar for structural support and a minimum thickness of 6 inches of concrete. The concrete cap will be covered by 3 to 4 feet of soil collected from within the area of disturbance associated with the vent hole. Topsoil from the vent hole areas will be pushed to one side of the disturbed area and leveled for use in reclamation at a later time. This topsoil will then be pushed back to cover the vent hole area during reclamation. All disturbed areas will be ripped and seeded in the late fall. Vent holes will be seeded with the Bureau of Land Management approved seed mix (see table below). The vent holes are normally expected to remain serviceable throughout the duration of mine operations. Reclamation of vent sites will normally be conducted as part of final reclamation and closure of all mine facilities.
