Section 7.0 Operation Schedule <br />The following operation parameters are forecast: <br />• 5 months per year operation (approx. 150 days per year) weather permitting <br />• active operation will be maximum 6 days per week, 10 hours per day <br />• move approximately 200 cubic yards per day, or 30,000 cubic yards per year, or 45,000 tons <br />• process approximately 200 cubic yards per day of gold bearing gravel through the wash <br />• plant <br />• a rock grizzly may be located in the active pit to avoid transporting large rock to the processing <br />plant <br />• strip an average of 6" of topsoil on virgin areas and either directly respread on previously mined <br />and regraded areas or place in a stockpile for use in reclamation. <br />It is expected that the swell of the virgin gravel material when mined will be 20 %, however, since some <br />material will then be sold as road base and other construction material, the net gain/loss in mining virgin <br />areas is more or less zero. All material that cannot be reasonably sold will be backfilled in the mining <br />operation. Reclamation plan details are described in Exhibit E. <br />The mining timetable for the gold operation is given below: <br />Mining Timetable - Gold Operation <br />Task # Description <br />1 Enlarge the mining water pond holding the mining <br />water from the Sacramento ditch <br />2 Enlarge road to access wash plant and install underground <br />water pipeline down hill for wash plant water supply <br />3 Complete set -up of wash plant <br />4 Mine Area 1 and send gold bearing gravel to processing <br />Plant, doing concurrent reclamation <br />6 Mine Areas 2 and 3 and do concurrent reclamation <br />7 Start Mining Area 4 from the north and re- establish <br />Westerman Ditch in new location <br />8 Finish Mining Area 4 <br />Time Needed in months <br />1.0 <br />1.0 <br />1.0 <br />55.0 <br />38.0 <br />22.0 <br />9 Regrade site and sell remaining gravel stockpiles. <br />10 Remove all equipment from site. <br />11 Place substitute topsoil on regraded areas. <br />12 Place topsoil on prepared areas <br />13 Seed, mulch and place mulch in remaining reclaimed area <br />Total Time <br />Sullivan Aggregate Pit March 2015 D -8 <br />22.0 <br />2.5 <br />0.5 <br />1.5 <br />1.0 <br />1.0 <br />146.5 months <br />
