The Shinkolobwe mine produced the most economical uranium ore in the world and was used for the Manhattan Project and subsequent nuclear weapons produced by the United States in the 1940s and 50s. Before World War II, uranium extracted here was originally taken to Belgium to be processed; this supply was captured by the Wehrmacht in 1940 and subsequently used for the unsuccessful German nuclear program.
