No explosives will be used in conjunction with the mining and reclamation operation. <br /> 2. Mining Timetable <br /> An average of yearly production values from the last five years for the King Pit is 100,000 tons <br /> per year. Therefore, 84 years of mining are possible based on the 8,384,440 CY of available <br /> gravel resource added to the north of the currently permitted King Pit. <br /> The mining schedule is planned to minimize disturbance by reclaiming mined-out areas as new <br /> mining phases become active. Note: If large contracts are awarded to the site, production could <br /> increase to the permit maximum, thereby curtailing the life of the pit. On the other hand, if <br /> contracts are less than anticipated,the life of the pit could be extended. <br /> 3. Mine Facilities and Operation <br /> It is extremely unlikely that any toxic or acid-producing materials will be encountered during the <br /> mining operation since past mining shows that the material mined is strictly alluvial in nature. <br /> However, in the event that such materials are encountered, they will be covered with subsoil and <br /> topsoil from onsite stockpiles to the same depths outlined in the reclamation plan and no more <br /> mining will occur-in the area. <br /> An approximately 8 acre portable processing area is located in the northern extent of the <br /> currently permitted site. Gravel processing equipment is portable and the processing area will <br /> move and follow active mining throughout the site. Portable mining equipment such as loaders, <br /> dozers, trucks and excavators will be serviced on an as-needed basis onsite. Upon reclamation, <br /> all portable equipment will be removed from the site. A summary of equipment and related tanks <br /> that may exist on site at any given time is listed below. <br /> - A portable asphalt plant with associated tanks (outside Contractor permitted with Alamosa <br /> County) <br /> - A portable concrete plant with associated tanks <br /> - Truck scales <br /> - Equipment parking and maintenance <br /> - Overflow resource stockpiling <br /> King Pit XL< ;aaa as�oc�acce $�.,� <br /> February 2018 D-3 <br />
