~'c i>~ 112 2 2 The area will contain no water diversion or impoundment other than a galvanized steel water tank of 20,000 gat. capacity for domestic and fire-fighting use. The size of the area of major disturbance is 1.9 acres which is old dump area. The area of moderate disturbance including the haulage road.to the mill is 4.5 acres. 112 2 h Shaft rehabilitation including guide change will be completed in April. of 1.981. Initial development including pockets, drifts, raises and stope development will be completed in March of 1982 and stoping wilt commencer Further development to prepare blocks of•ore will continue in sequence as required. b) C-7 Zone The surface plant area is located on a moderately sloping hill- side adjacent to the Cresson Mine Surface Plant (inactive). 112 2 f The C-7 Ore Zone is nearly vertical striking northerly. The '~ rockois igneous in origin.. Access to the zone will be through a decline ~~''~~ at 8 which will flatten out under the ore zone. Mining will be done~lo~y ~•='x by a modified sub-level stoping method. Raises will be driven from ~ ~y the haulage to the surface for ventilation and secondary access. A g e,J crown pillar will be left at the surface to prevent subsidence. ~` ~-~.~~ Surface preparation will include a trench cut in line with the ~•' decline in which a 50 foot tunnel liner will be conStrucbdd. This area will be back-filled to form the portal of the decline. Minor amounts of earth work will be required to level out for a compressor building foundation and a water tank. The area at the portal will•be built up to the south in a fan- shaped configuration with waste rock from the decline and haulage to form a flat surface area. This will be utilized for storage of material and later storage of rock either on the ground or in a bin for transportation to the mill. The surface area will have no water impoundments. The size of the area of major disturbance will be 1.0 acres. ~~~` This will include the surface plant and three areas along the line of the a~ decline and haulage where .the overburden will be removed to permit ~~ ' a'~ raises from below to come to the surface in competent rock. la~L ~~ls •'~L ~ cam. The surface plant preparation will begin. in December of 1980 6 ~ ~~,~ ~ ''~ and be completed in February of 1981. The decline and initial portion of the haulage will be completed by July of 1981. Subsequent develop- ment will •take,pl•ace through the end of the year 1981 including the driving of 3 raises. stoping will commence in 1982. -•-n 004363
