2. Mining Timetable <br /> Projected average annual production for the Bradford Mesa Quarry is 1,000,000 tons per year. It <br /> is currently estimated that 30-60 million tons of basalt are available to be mined within the <br /> quarry. Mining will be completed based on market conditions; therefore, with an average <br /> estimate of 45 million tons of basalt available mined at a rate of 1,000,000 tons per year, mining <br /> of the Bradford Mesa resource will occur over 45 years and is projected to be completed by 2065 <br /> with final reclamation to be completed by 2066. <br /> The mining schedule is planned to minimize disturbance by reclaiming mined-out areas as new <br /> mining phases become active.Note that if large contracts are awarded to the site, production <br /> could increase and reduce the life of the pit. On the contrary, if contracts are less than <br /> 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 as the site was historically rangeland with minor more riparian areas near the <br /> Bradford Reservoir. However, in the event that such materials are encountered, they will be <br /> covered with subsoil and topsoil from onsite stockpiles to the same depths outlined in the <br /> reclamation plan and no more mining will occur in the area. <br /> An approximately 30 acre processing area will be located in the central extent of the mesa top to <br /> service the two main mining trends. Aggregate processing equipment is portable and the <br /> processing area may move and follow active mining throughout the site. Portable mining <br /> equipment such as loaders, dozers, trucks and excavators will be serviced on an as-needed basis <br /> onsite. Upon reclamation, all portable equipment will be removed from the site. A summary of <br /> equipment and related tanks that may exist on site at any given time is listed below. <br /> - A portable asphalt plant with associated tanks <br /> - A portable concrete plant with associated tanks <br /> - Truck scales <br /> - A portable office trailer <br /> - Equipment parking and maintenance <br /> Bradford Mesa Quarry <br /> January 2020 D-13 <br />
