Dundo is a mining town in northeastern Angola. It lies 15 miles (24 km) south of the Democratic Republic of the Congo border. Founded near a site where diamonds were first discovered in 1912, the town was developed as a planned community privately operated by Diamang (Companhia de Diamantes de Angola). This international consortium, monopolizing the exploitation of the area between the early 1920s and 1971, was nationalized by the Angolan government in 1977. Until 1980 the mines, generally southeast of Dundo in the alluvial till of riverbeds, annually produced nearly 10 percent of the world’s total output of gem-quality diamonds.
