Platinum
Platinum exists in higher abundances on the Moon and in meteorites. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example.
Sub-Saharan Africa
The region is a major exporter to the world of gold, uranium, chromium, vanadium, antimony, coltan, bauxite, iron ore, copper and manganese. South Africa is a major exporter of manganese as well as chromium. A 2001 estimate is that 42% of the world's reserves of chromium may be found in South Africa. South Africa is the largest producer of platinum, with 80% of the total world's annual mine production and 88% of the world's platinum reserve. Sub-Saharan Africa produces 33% of the world's bauxite, with Guinea as the major supplier. Zambia is a major producer of copper. Democratic Republic of Congo is a major source of coltan. Production from Congo is very small but has 80% of proven reserves. Sub-saharan Africa is a major producer of gold, producing up to 30% of global production. Major suppliers are South Africa, Ghana, Zimbabwe, Tanzania, Guinea, and Mali. South Africa had been first in the world in terms of gold production since 1905, but in 2007 it moved to second place, according to GFMS, the precious metals consultancy. Uranium is major commodity from the region. Significant suppliers are Niger, Namibia, and South Africa. Namibia was the number one supplier from Sub-Saharan Africa in 2008. The region produces 49% of the world's diamonds.
