Update August 2014

COMINAK has been mining deep uranium deposits in northwestern Niger since 1978. 

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. 

Production of the mining site

In 2013, COMINAK turned in excellent performance with the production of 1,508 metric tons of uranium, bringing the total production for the mining company since it began operations to more than 65,900 metric tons.

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 1,800 employees, 98% of whom are Nigerien. Its headquarters are at Niamey.
