The Etiro pegmatite is located 20 km north of Karibib on the farm Etiro 50 and is a rare-metal pegmatite mined mainly for beryl during the early 1960s. Accessory minerals include columbite-tantalite, amblygonite, bismuth minerals, bismuth, tourmaline and phosphate minerals. Bismuth minerals comprise native bismuth, bismite, sillenite, bismutite and zavaritskite. (Extracted from Schneider 1992)
