Compagnie des bauxites de Guinée (CBG) is a Guinean mining company. Since 1963 it has extracted bauxite from the notable mine in Sangarédi, in Boké Region in Guinea. It is 49% owned by the Guinean State, with the remainder owned by the Boké Investment Company, a 100%-owned subsidiary of Halco Mining, a consortium opened in 1962 by Harvey Aluminum Company to run mining operations in Guinea. Halco's stock is owned by Alcoa (45%), Rio Tinto Alcan (45%) and Dadco Investments (10%). Guinea is the world's 5th largest producer of bauxite, yet the country holds the world's largest reserves of the valuable ore used to produce aluminum. Estimates of the country's reserves rise as high as 25 billion tons, or the majority of the world's bauxite. More information...
