Schedule of Operations The mine is expected to operate from 5:00 AM to 9:00 PM. When the portable crushing plant is on site, it runs about 14 hours per day 6 days per week. Operating hours will be based on product demand. Mine Area Details The expansion's reserves are divided into mining areas with each area having multiple phases. While one phase is being mined the previous phase will be reclaimed. Once an area's reclamation earthwork has been completed the pit will be allowed to flood. This separation of areas and phases will limit the overall disturbed area. Areas will be mined in order. Material is expected to be transported from Areas 1 and 2 byoff-highway truck prior to being fed into the primary crusher. Area details can be seen below.
