In any case, mining in each pit will proceed to a level no greater than 500 feet below the outcrop. The maximum overall pit slopes and bench geometry will be designed to enhance slope stability from data determined after an extensive geotechnical program. Haul roads leading from the pit areas are designed at a maximum 10 percent grade.
