No explosives will be used in conjunction with mining and reclamation operations. <br /> 2. Mining Timetable <br /> An average of yearly production values from the last five years for the Alma Placer Mine is the <br /> processing of 60,000 tons of gold-bearing gravel per year. Since the operation will only be <br /> active for 6-9 months per year, and the total resource to be mined is 500,000 to 600,000 CY,the <br /> full gold mining operation will take approximately 8.5-10 years, provided no new resource areas <br /> are identified, no plant expansion occurs, or other unforeseen factors occur. Gravel resource may <br /> be recovered and sold as a byproduct to gold placer mining for approximately 13 years. <br /> The mining schedule is planned to minimize disturbance by reclaiming areas as additional <br /> mining is undertaken. If large contracts are awarded to the site, production could increase to the <br /> permit maximum,thereby curtailing the life of the pit. On the other hand, if contracts are less <br /> than anticipated,the life of the pit could be extended. <br /> 3. Mine Facilities and Operation <br /> A summary of equipment and related tanks used during gold mining and secondary gravel <br /> processing is shown below: <br /> • Gold wash plant, a 170' x 80' metal building built on a concrete foundation <br /> • office/warehouse/shop— 100' x 45' x 22' high walls with partial concrete floor <br /> • assorted power poles <br /> • Portable restrooms for employees and visiting personnel <br /> • equipment storage building (metal) on skids for easy removal with 24' x 50' concrete <br /> block walls sealed for secondary containment <br /> • insulated pump house (18' x 34'; steel &wood construction and contains 88 horse power <br /> motor), located near the South Platte River where Access 1 enters Highway 9 <br /> • 12"plastic water line used to deliver water from the pump house to the processing plant <br /> • 36" stacker conveyors remove waste material from the processing plant <br /> • 36"portable overland conveyor brings gold-bearing gravel from the active cut to the <br /> processing plant <br /> • 5" grizzly in pit (2) <br /> Alma Placer Mine Grm t x WL.
