Mount Nimba is a 1 mile high iron
ore mountain with the highest grade iron deposit in the world. It
is also the location of important minerals. Iron ore mining on Mount
Nimba accounts for approximately 1 per cent of the world production,
currently set at around 900 million tons.
It reaches
its highest elevation at Mount Nimba (5,748 feet [1,752 m]) in
Guinea. Surrounded by lowland rain forest to the south and
savanna to the north, the mountains are the source of the Nuon
(Nipoué, Cestos) and Cavalla rivers, which form the
Liberia–Côte d'Ivoire boundary and the Ya river in Yekepa.
