Mica Kop


Pegmatite occurs about 35 km north of Kenhardt, on the portion of N'Rougas Noord, known as Straussheim. there are several very prominent pegmatites and No. 1 forms a hill known locally as Micakop. Mining since 1952 has produced several hundred tons of beryl from the three main pegmatites in the area. Beryl production ceased when Straussheim mine started producing cassiterite.
