The Postmasburg Manganese Field's (PMF) history began with early geological mapping in 1930 and local prospecting in 1940s. [1] Systematic exploration in the 1950s led to discoveries at Gloria mine (1953), Nchwaning mine (1955), Mamatwan mine (1957), and Wessels mine (1958). Mining commenced with Gloria Mine in 1957, followed by Nchwaning in ...
Kalahari Manganese Field geologic map. 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.

Philip Hazel, the British computer programmer, emigrated to Kuruman with his family after WWII; his father worked in the offices of an asbestos-mining company. [9] The Kalahari Meerkat Project, made famous by the television series Meerkat Manor, is located nearby.
Olmiite is a rare calcium-manganese silicate that was named after an Italian mineralogist called Filippo Olmi. It was approved by the IMA in 2006, with its first description published in 2007. [ 1 ] Around 2001, a large amount of specimens believed to be poldervaartite was discovered at the N'Chwaning II mine, which is near the Wessels mine ...
The Kalahari Manganese Field (KMF) located in the Northern Cape of South Africa is a source of manganese. [11] Hotazel Manganese Mines, [12] near Hotazel; Khwara Manganese [11] Mokala Manganese [11] Tshipi Borwa Manganese Mine [11]
The Wessels mine is a mine located in the west of South Africa in Northern Cape. Wessels represents one of the largest manganese reserve in South Africa having estimated reserves of 198.8 million tonnes of manganese ore grading 55% manganese metal.
Jacobsite is a manganese iron oxide mineral. It is in the spinel group and forms a solid solution series with magnetite. The chemical formula is (Mn,Mg)Fe 2 O 4 or with oxidation states and substitutions: (Mn 2+,Fe 2+,Mg)(Fe 3+,Mn 3+) 2 O 4.

A. J. Clement researched the story in 1964 and advanced a new theory. Clement claimed his study of Farini's description of his route highlighted inconsistencies in Farini's story. Clement concluded that Farini went deep into Southern Africa, but he never actually went to the heart of the Kalahari where he claimed the Lost City was sited.
