    A 21-foot diameter cylinder with a 14-foot wide by 17-foot 8-inch long “tail” was undercut by the conveyor drift below. The ore bins, each 28 feet in diameter and 90 feet deep, were cut in much the same manner as the crusher chamber. Undercutting the bins reduced the depth of hole required to 73 feet.
