COMINAK, operator of the largest underground uranium mine
COMINAK has been mining deep uranium deposits in northwestern Niger since 1978. In preparation to exploit new deposits, COMINAK is implementing a comprehensive action plan to optimize production and consolidate its position as the operator of the second-largest active uranium mine on the African continent and the largest underground mine in the world.
COMINAK (Compagnie Minière d’Akouta) was founded in 1974. AREVA holds 34% of its capital; SOPAMIN (Niger) 31%, OURD (Overseas Uranium Resources Development Company Ltd, Japan) 25%, and ENUSA (Empresa Nacional des Uranio S.A, Espagne) 10%.
The largest underground uranium mine in the world
The mine is located at a depth of 250 meters and has more than 250 kilometers of tunnels. Its uranium ore has an average grade of 4‰ (4 kg of uranium per metric ton of ore).
After extraction, the ore is dynamically processed (crushing, fine grinding, chemical treatment, washing, filtration, drying and packaging) to obtain uranium concentrate. This is done in an on-site plant with an annual production capacity of 2,000 metric tons.
AREVA and Niger a Sustainable Partnership
As the country’s first private employer and main industrial partner for the past 40 years, AREVA is a major stakeholder in the Nigerien economy. Mining activity generates important revenues that have a positive impact on the development of social and public initiatives.

Production of the mining site
In 2012, COMINAK turned in excellent performance with the production of 1,506 metric tons of uranium, bringing the total production for the mining company since it began operations to more than 64,400 metric tons.
At the current rate of production, mining of these deposits can continue for 15 more years.
Mining operations that support local development
Since 2011, COMINAK has had ISO 14001 and OHSAS 18001 certification for its environmental, health and safety management systems.
In line with AREVA’s policy, COMINAK also contributes to providing health and social services in an isolated region, thus helping to improve living conditions for the local populations.
COMINAK has about 1,250 employees, 98% of whom are Nigerien. Its headquarters are at Niamey.
