Chisuki: Mica, Tin, Tantalum
Tin, together with tantalum, was being mined on an irregular basis by small-scale workers from the Tin Belt of southern Zambia, east of Choma. Tin occurs as cassiterite in pegmatites and in placers. Stanniferous quartz-muscovite-feldspar-tourmaline pegmatites intruding schistose metasediments occur over a strike length of 100km centred on Masuku Mission and approximately 150 separate occurrences have been recorded. The average annual production was around 10t of tin-tantalum concentrate and was sold as such to local processors.
