The limestone averages 18.3 m (60 ft) in thickness, with mining planned in two lifts (i.e., initial development and benching). The height of the initial development was 7 m (23 ft). Secondary bench mining removed an additional 9.1 m (30 ft) from the floor, resulting in a total planned mining height of 16.2 m (53 ft).
Limestone was found at a depth of 2,214 feet, and its presence was so far traced down to 2,285 feet with a thickness of 71 feet. Given that this thickness remains the same over the 50-square km ...
