As regards mineral resources, some people have talked of geological scandal in view of the existence of abundant and varied wealth. The Guinean subsoil conceals significant deposits of Bauxite = 25 billion tons, accounting for the 2/3 of world reserves approximately;
Gold = 1000 tons;
Diamond = 30 million carats.
Moreover, Guinea has the richest high-grade iron ore deposits in the world but which have not yet been developed: the SIMANDOU range contains 2 billion tons and the Mount NIMBA 1 Billion tons.
Apart from the aforementioned wealth, the Guinean soil contains limestone deposits (Mali, Siguiri, and Kindia) not yet exploited and there are indications of the presence of nickel, cobalt, titanium, and uranium.
