Sizable deposits of iron ore also exist. Other known mineral resources include diamonds, gold, cobalt, nickel, uranium, petroleum, and platinum.

Most ethnic groups grow a variety of crops, using very basic tools.
Maize, manioc, and rice are the staples, but squash, melons, sweet potatoes, peppers, and tomatoes are also grown. Major tree crops include bananas, coconuts, mangoes, and papayas. Cattle, sheep, and goats are raised, but their milk is not used. Dogs and chickens are seen in almost every village. Although the Jahanke are small in number, they are a very significant group.
