Sierra Leone Selection Trust
From Wikipedia, the free encyclopedia
The Sierra Leone Selection Trust was a subsidiary of De Beers corporation which had exclusive mineral mining rights in Sierra Leone beginning in 1935 which was scheduled to last for 99 years. In 1955, the SLST abandoned night-wide mineral mining and settled on mining the Yengema and Tongo Fields. However, with the creation of the Sierra Leonean parastal National Diamond Mining Company in 1971, the diamond company was effectively nationalized, ending the SLST in Sierra Leone.
