As Stan said, the main problem in Subsaharian Africa is not natural resources management but rather governance.
Katumba Mwanke in DRC is not fully cold yet that his former protégé is selling the shares of the national mining company (GECAMINE) to China for multibillions contract. Who could resist?

The problem goes even deeper. In many countries there was first a nationalization phase in the 70th. But, as Zimbabwe now, it was so badly managed that most of the one time wealthy companies went down to bankrupt, as for GECAMINE for instance. Then there was a phase of privatization supported by IMF. This allowed wealthy local people to invest in join venture with international companies. One of the best example is the Museweni family who took advantage of being at the head of Uganda to basically put an almost monopoly grip on the mining and oil business in Uganda.

Such attitude does trigger rebellion/insurgencies/contestation/civil wars…. Uganda is an interesting model cause after several decades of full dictatorship, Museweni managed to more or less pacify his country. (By pacify I hear having no fully operational armed groups on your land, not the end of those armed groups). Then he had to do something with his army, cause unhappy generals are a great threat. He then turned to PMC, saracem and others. Put his generals at the head of several companies, had some support from former PMC CEO (Barlow, Bukingham…) and made the junction: his family was running both the natural resources and security sectors.

Fortunately for the Ugandans, now political civil opposition and majority are questioning his position, especially in oil.
Uganda's Museveni is more concerned with oil than the anti-homosexuality bill

There is a great ICG report on Chad oil: Chad: Escaping from the Oil Trap, Africa Briefing N°65, 26 August 2009

Which is a good case study of how natural resources are managed in Sub-Sahara Africa.
