CLAYS DEPOSITS IN BOTSWANA STILL BEING ANALYSED
The Chief Economic Geologist at the Department of Geological Survey Dr. Gomotsang Tshoso stated that the Department of Geological Survey is currently assessing the Letlhakeng Clay and Takatokwane clay deposits. Most of the analyzed samples show that the Letlhakeng clay is suitable for brick making. However analysis of samples is still ongoing and quantification will come after they are complete. She said.
Meanwhile, clay in Botswana is associated with Karoo deposits within the Ecca group and can be found in most parts of the country. Most of these clay deposits have to be evaluated and classified accordingly. Currently the clay is exploited in Makoro, Lobatse and Dipotsana areas only. Known clay reserves are estimated at 1 million tonnes at Lobatse Clay works and Makoro and the resource estimate is 7.2 million tonnes. The Lobatse Clay Works and Makoro use the clay for brick making (face brick and stock brick) while the Dipotsana quarry only manufacture stock bricks. Twenty-five tonnes of clay deposits for pottery has also been identified in Serule Siding. It is however, evident that the current mining areas do not meet the country’s demand. Tshoso concluded.
