Shinkolobwe is a mining town in the Katanga Province. The Shinkolobwe mine was used to produce uranium ire for the Manhattan Project, which led the the creation of the atomic bomb. Although the mine was closed in 1939, the U.S. Army reopened and extended its operations in the Congo, extracting thousands of tons of uranium. Security measures were taken as the Shinkolobwe mine was removed from maps and journalists denied access. The mine was officially closed on January 28, 2004 by presidential decrees. Claims have been made that both Russian and Iranian interests are known and possibly active near Shinkolobwe.
