Nchwaning mines

The N'chwaning mine (or N'Chwaning mines) are located in the Northern Cape Province of South Africa. N'chwaning has one of the largest manganese reserves in South Africa having estimated reserves of 323.2 million tonnes of manganese ore grading 42.5% manganese. There are three shafts, designated as N'Chwaning, N'Chwaning II and N'Chwaning III. The majority of the major mineral finds documented originate from the N'Chwaning II shaft. N'Chwaning is considered a single vertical hoist shaft. N'Chwaning II is a vertical skip shaft, currently still in production with an underground crushing facility. N'Chwaning III has two main shafts – a vertical personnel shaft and a decline shaft. N'Chwaning III additionally has seven underground silos for storing different grades of ore. N'Chwaning is known to produce high-quality mineral specimens of rhodochrosite, manganite, ettringite, inesite, jouravskite and other minerals. The N'Chwaning mine is located on the farm N'Chwaning 267, from which the name is derived. The license area also includes what was formerly known as the Black Rock mine area, and is situated in the manganese ores of the Kalahari Manganese Fields.
