r <br /> MINING PLAN AND TIMETABLE EXHIBIT D(CONT) <br /> materials, the natural progression of mining from one Phase to the <br /> next . This concurrent reclamation allows for reclamation work being <br /> completed in one phase while mining begins in another phase . <br /> The "direction of mining" arrows on EXHIBIT C-1 - MINING PLAN MAP show <br /> the applicant ' s best guess on how mining will progress through the <br /> mine areas at this time . Natural ground conditions and unforeseen <br /> circumstances may necessitate changes to the mining direction <br /> throughout the life of the mine. <br /> The RECLAMATION COST ESTIMATE- EXHIBIT L is based on the Operations Stage <br /> A plan to bond for initial setup of the Plants Site and support <br /> facilities . Included is an estimate for the Operations Stage B where <br /> it is based on an estimated disturbance area when the Phase 1 has been <br /> open for a few years . The acreage disturbed may increase or decrease <br /> as mining progresses . If it increases, a Technical Revision will be <br /> filed to adjust the bond amount to cover the changed cost estimate . <br /> Mining will start on the southwest of Phase 1 and progress to <br /> the east and south until the mining limits are reached. This will leave <br /> an open working face across the Phase as shown on the MINING PLAN MAP. This <br /> face will have a '/2: 1 slope and will be worked to the north, the exterior <br /> final slopes will beitiieia constructed using the overburden or shale <br /> from the excavated floor material . e� fRin el to allew ffe)y : � lt4-f� <br /> final: eficaelinef fftezl 1.e-' ; nefzm sand and-etravez If mining ends <br /> prematurely, the east/west working face will be reclaimed using a <br /> cut/fill sloping method instead of backfilling. <br /> S1'Trr-y wall Ceu2L1 7C-Z5 if the 'Ae <br /> will i— Jeaseei en t i.e �eiepth f t i.,e ,a e6 sl+ T t-.e Deei�e & Ault rei e <br /> The setbacks to be used in each Phase are shown in the table on <br /> the EXHIBIT C-2 STRUCTURES MAP. The aggregates will be removed and stored <br /> on the Plant Site area in Phase 4 for processing. The plan is to use <br /> conveyors or off-road haul trucks to move the material from the working <br /> face to the Plant . <br /> As mentioned above, the proposed mining sequence may change due <br /> to unforeseen circumstances such as market conditions, variations in <br /> the natural deposit, agreement restrictions with structure owners, <br /> etc. At this time, the plan is to mine them sequentially from 1 <br /> L.G.
