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. In this mines Manganese Mining The mining of manganese ore was a very important economic activity in Arkansas between 1849 and 1959. The region around Batesville (Independence County) including about 100 square miles located in northwestern Independence County , southeastern Izard County , and northeastern Stone County has produced more than ninety-eight percent of the manganese ore
