Source of the first atom bomb's uranium

The Shinkolobwe mine in the Katanga Province is also known as the Kasolo Mine, Chinkolobwe, and Shainkolobwe. Shinkolobwe's urainium deposits were discovered in 1915. This mine, near the southern Congolese town of Likasi, produced uranium for the first atomic bombs. The Shinkolobwe uranium mine ceased was closed in 1960, when Belgium granted Congo independence. Belgian authorities filled the main uranium shaft with concrete.
