below the active pit floor that outlet to the Yamp River. An approved Colorado Department of <br /> Public Health and Environment discharge permit covers the site dewatering. <br /> 3. Active Mining Area <br /> Roughly 50 acres of disturbance area will be active at any given time. This is the basis of the <br /> bond scenario outlined in Exhibit L. Contempouraneous reclamation will maintain this <br /> disturbance limit. <br /> 4. Mining Timetable <br /> The following timetable is a best estimate of the sequence of operations for the life of the mine <br /> based on mining and selling 200,000 tons of total product per year: <br /> Table D-1 Mining Timetable <br /> Description Time <br /> Reclaim final pit and processing area 2 years <br /> The mining schedule is planned to minimize disturbance by reclaiming areas as additional <br /> mining is undertaken.Note: If large contracts are awarded to the site,production could increase <br /> to the permit maximum,thereby curtailing the life of the pit. On the other hand, if contracts are <br /> less than anticipated,the life of the pit could be extended. This table is based on a reasonable <br /> projection of average production rates. <br /> 5. Products to be Mined <br /> The Bunn Ranch pit will mine sand and gravel for the production of construction materials <br /> products including, but not limited to: <br /> • Hot mix asphalt <br /> • Readymix concrete <br /> • Washed rock <br /> • Crushed rock <br /> • Pit run <br /> • Construction fill <br /> Bunn Ranch Pit <br /> January 2021 D-2 <br />
