Mining in Gabon Wikipedia

Gabon was the richest of the former French Equatorial African colonies in known mineral deposits. In addition to oil, which accounted for 80% of the country's exports in 2004, Gabon is a world leader in manganese. Potash, uranium, niobium, iron ore, lead, zinc, diamonds, marble, and phosphate have also been discovered, and several deposits are being exploited commercially.
