Most underground mining of the manganese is generally done by room and pillar method. Mining at Nchwaning and Gloria mines uses two shafts when it was initiated in 1981, one vertical hoisting shaft that is 450m deep and another vertical shaft. Now further rooms and pillar rooms are made with low grade ore for easier mining.

Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in ironore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.
