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).

Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells.

Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
