Gemstones and precious metals

In Botswana, the Department of Mines and Mineral Resources, Green Technology and Energy Security maintains data regarding mining throughout the country. Debswana, the largest diamond mining company operating in Botswana, is a joint venture, 50% owned by the government.

The mineral industry provides about 40% of all government revenues. Uranium mining has not started in Botswana, however the Letlhakane Uranium Project in Africa is one of the largest undeveloped uranium projects. The government announced in early 2009 that they would try to diversify their economy and overreliance on diamonds.
