<br />E7CHIBIT E -- Reclamation Plan <br />The reclamation plan will follow the criteria has submitted in the July, 1996, Closure Plan <br />Document, including the costs estimates and task timetables corrected as noted. The amended <br />reclamation plan anticipates that approximately 2.5 million tons of gypsum reserve will remain <br />in place, with currently vertical highwall areas reduced to a maximum 1:1 slopes reflecting long <br />term slope stability. No attempts will be made to revegetate the gypsum and other rock talus <br />slopes created by drilling and blasting of the highwall areas. There will be approximately 24 <br />acres of relatively flat lying areas(mining levels), regraded slopes along the hangingwall contact <br />of the ore body at 2.S:1 slopes, and various roadways that will be revegetated to native grasses, <br />shrubs, and trees. Planting media from other disturbed areas within the affected land boundaries <br />will be hauled to the flat mine bench areas and applied at a thickness of 12" prior to planting and <br />mulching operations. The reclamation plan will address each major area within the affected <br />land boundaries starting with the highest elevation of the mine site, the footwall(oldest rock) and <br />proceeding through the various areas in the mine to the hangingwall rock(youngest rock) . <br />All rock volumes noted below are from analysis of cross sections drawn from topographic maps <br />created from 1945 aerial photo work. A11 tonnage calculations are based on a average rock <br />density factor of 160#/cubic foot. <br />GOLD HILL <br />This 10 acre highwall contact in the highest disturbed ground and most visible at the site. <br />Elevations range from 6935' to 7250'. The exposed footwall is evident along much of the <br />highwall, as veneer removal operations have exposed the rolling, black to dark grey limestone <br />bed underlying the gypsum sequence. Two main areas of concern will be addressed including <br />the gypsum veneer removal to dislodge gypsum left on the contact in the past, and gypsum and <br />anhydrite mine benches located along the lower elevations of Gold Hill. The veneer is being <br />removed by hand barring, drilling and blasting of the gypsum left along the footwall contact. <br />This work is being performed at the present time. Loose veneer material rolls down the 55 <br />degree footwall rock contact to a catchment area behind a rock berm at the bottom of the 200' <br />slope of the Gold Hill Highwall. The mine benches will be removed via drilling and blasting <br />followed by bulldozer grading to result in a rock talus slope not exceeding 1:1 and portraying <br />good slope stability. <br />l) Sections 1500 through 2500, gypsum veneer volume estimates: <br />Section 1500 1000 tons <br />Section 1600 1000 tons <br />Section 1700 1000 tons <br />Section 1800 1000 tons <br />Section 1900 2000 tons <br />Section 2000 2000 tons <br />Section 2100 3000 tons <br />Section 2200 3400 tons <br />Section 2300 3000 tons <br />
