Mineral production was not significant in 2001, and mining activities were limited to small-scale production of clay, granite, limestone, and sand. Bauxite, diamonds, gold, and phosphate were economically promising minerals being explored; the Farim deposit had a phosphate resource of 166 million tons. Large deposits of bauxite, amounting to 200 million tons, were discovered in the Boé area in the late 1950s; lack of capital and transportation has hindered exploitation. The bauxite and phosphate resources were of low grade. Election of a new government in 2000 was seen as a step toward ending military conflicts that followed a 1998 military coup. The 1999 Mines and Minerals Act reformed mineral exploration and mine development and production, setting sizes and terms for exploration, mining, and prospecting leases.
