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 ...

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 ...
Even under the hot conditions of the Kalahari Desert, many species survive; in fact the country has more than 2500 species of plants and 650 species of trees. [2] Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants. [3]

Established in 1961 it covers an area of 52,800 square kilometres (20,400 sq mi) (larger than the Netherlands , and almost 10% of Botswana's total land area), making it the second largest game reserve in the world.

Ancient dry riverbeds—called omuramba—traverse the central northern reaches of the Kalahari and provide standing pools of water during the rainy season. A semi-desert, with huge tracts of excellent grazing after good rains, the Kalahari supports more animals and plants than a true desert, such as the Namib Desert to the west. There is ...
