Katanga Copper Crescent; Zaïre


An opencast copper mine, abandoned in the late 1980s.

Oxidised uraninite lens in the dolomitic R2 formation of the Roan series, Middle Katangian, Precambrian Age. According to F. Colette, who found the lens, there were 4,150 tonnes of truckloads that were transported to the uranium dump on the Musonoi Extension site. From there, collectors could collect before the dump was sent to the Kolwezi concentrator.
