It is difficult to imagine a more fitting name for a uranium mine. Discovered in 1915 by English geologist Robert Rich Sharp in the bush of what was then the Belgian Congo, the Shinkolobwe mine produced the most concentrated uranium ore in the world -- ore so rich that uraninite crystals of one to four centimeters were common. From this remote site, 145 kilometers northwest of Lubumbashi, came the material that ended World War II, that shaped the nuclear arms race, and that nations have fought over, smuggled, and tried to seal away ever since.

The uranium-bearing deposits formed 630 million years ago, when mineral-rich solutions percolated into dolomitic shales of the Precambrian Mine Series within the Katanga synclinorium. Alongside uranium, the deposits yielded...

The mine was officially closed by presidential decree on January 28, 2004. But closure on paper has not meant closure in practice. In July 2004, eight people died and...
