The Mounana Uranium Mining Complex in the Haut-Ogooué province was one of the world's most significant uranium extraction sites for over four decades. Operations began in 1958 under the management of the Compagnie des Mines d'Uranium de Franceville (COMUF), playing a critical role in supplying France's nuclear program. During its lifespan, the site produced approximately 28,000 tons of uranium, establishing Mounana as a symbol of Gabon's industrial era. Mining activities were ceased in 1999 following the depletion of economically viable reserves. The closure necessitated extensive environmental remediation efforts to secure radioactive tailings and minimize environmental exposure for the local population. Today, Mounana stands as an industrial heritage site, reflecting a history of technological cooperation and the complex challenges of resource extraction. The mine's legacy remains under continuous monitoring by international agencies to ensure long-term regional safety.

📋 Practical info
What is this place?
The former Mounana uranium mining complex was once one of the world's most important uranium sources, shaping Gabon's mining history. Today, the site is a decommissioned industrial area, recalling the economic significance of uranium mining for the country.
Visiting
Due to decommissioning and associated safety measures, access to the site is generally not allowed. From surrounding roads, remaining facilities and the open pit can be viewed from a distance.
Where to view it
A good viewpoint is the hill at the edge of the former open pit, reachable from the access road. From here, a view opens over the vast pit and the decommissioned facilities of the complex.
Local products
In the Mounana region, there are no direct mining products for visitors today. On local markets, travelers can buy agricultural products such as cassava, bananas, and peanuts grown in the area.
Active season
Mining has not been active since the cessation of extraction in the 1990s. The area is calm year-round without seasonal peaks, but the markets are liveliest after the local agricultural harvests.
Nearby
A visit to the former mining complex can be combined with exploring the nature reserves and waterfalls of the Haut-Ogooué region. The city of Franceville also gives cultural attractions and markets for travelers.
