The Kalahari Manganese field is located in the Northern Cape Province, 700km south-west of Johannesburg, South Africa. It contains approximately 80% of the world's known high-grade manganese ore reserves. The district yields four million tonnes per annum (Mtpa), which is mined mainly by two companies: Samancor and Assmang. Originally established in 1935, Assmang is jointly .
