Due to the mostly flat geometry of the ore lenses, all planned production mining will be completed using drift and fill mining. The final choice of mining method will depend upon the geometry of the stope block, proximity to main access ramps, ventilation and escape routes, the relative strength or weakness of the mineralized material and adjacent wall rock, and finally the value or grade of the mineralized material. The choice of mining method will not be finalized until after the stope delineation and definition drilling is completed. Development and production mining will be performed by a qualified mining contractor. ACCESS DEVELOPMENT Underground access to the mining areas will begin with a portal on the North side of the existing pit and ramp down. Initial work will consist of 4,557 feet of decline from the portal down to approximately the 4600-foot elevation and 889 feet of drill laterals. The drill laterals are located directly above the Helen and Gap deposits. Primary access drifts are designed 15 feet wide and 17.5 feet high to permit 30-ton haulage trucks and provide a large cross section for ventilation. Drift gradients will vary from – 15% to + 15% to reach the desired elevation. Secondary drifts, spiral ramps and vertical raises will connect the haulage drifts to provide a pathway for ventilation to the surface and serve as a secondary escape way. GROUND SUOOPRT It is expected that Swellex rock bolts along with welded wire mesh will be able to control all co ........
