In 1883, a shaft was sunk and another 400 tons of manganese ore was removed for assay. It was determined that the ore was unsuitable for steel production, and the mine was abandoned. The piles, if found through 120 years of overgrowth, can produce some excellent micro minerals.
Where Does Manganese Mining Occur? Manganese is the fifth most abundant metal found in the crust of the earth. Although 80 percent of manganese resources are found in South Africa, manganese is also mined in Australia, China, India, Ukraine, Brazil and Gabon.
History. The ore body was discovered in 1940 by Assmang, and led to the acquisition of a manganese outcrop. The properties on which the ore is situated were subsequently acquired by Assmang, and led to the 1975 commissioning of the Gloria mine (medium grade carbonated ore) as well as the later commissioning in 1972, 1981 and 2004 respectively of the N'Chwaning I, I and III shafts.
