The Republic of Niger has formally inaugurated the Timersoï Uranium Mining Company (TSUMCO), a newly established state-owned entity tasked with assuming control of the Arlit uranium deposits in the country’s northern region. This landmark initiative simultaneously signals the conclusion of the long-standing concession granted to the French conglomerate Orano—formerly known as Areva—over one of the Sahel’s most pivotal mining basins. The move aligns with the transitional government’s broader strategy in Niamey to reclaim ownership of the nation’s natural resources.
TSUMCO: a strategic pivot in Niger’s uranium sector
The establishment of TSUMCO underscores the government’s resolve to domesticate the entire value chain of uranium, a mineral of critical importance. The Arlit site, in operation since the early 1970s, has historically served as a cornerstone of France’s civil nuclear fuel supply chain. The transition to a publicly managed company shifts the capital structure decisively in favor of the State, elevating its role from minority stakeholder or technical partner to the direct operator of this strategic asset.
This transition introduces significant operational challenges. Uranium mining demands specialized expertise, stringent radiation protection protocols, and reliable market access. TSUMCO must urgently address key industrial decisions, including the integration of local workers, the maintenance of aging infrastructure, and potential partnerships for processing and exporting the extracted ore.
Orano’s legacy ends in Niger
For Orano, the loss of the Arlit concession closes a chapter spanning more than five decades. The group, which evolved from Cogema to Areva before adopting its current name, managed Niger’s uranium sector through two flagship subsidiaries: the Société des mines de l’Aïr (Somaïr) and the Compagnie minière d’Akouta (Cominak), the latter having already ceased operations in 2021. Since the July 2023 coup d’état and the subsequent strain in diplomatic relations between Paris and Niamey, the operational environment for French-owned assets in Niger has steadily deteriorated.
The withdrawal of the Imouraren mining permit, announced in 2024, served as an early indication of this shift. The formal end of Orano’s concession at Arlit now cements Niger’s intent to permanently sever ties with its historical mining partner. Legal disputes may persist, particularly as Orano has already initiated international arbitration proceedings on other Niger-related cases.
Mining sovereignty and shifting alliances
The formation of TSUMCO reflects a wider regional trend. In both Mali and Burkina Faso, governments emerging from military-led transitions are revising mining codes, renegotiating concession agreements, and increasing state participation in extractive projects. The tripartite alliance of Sahelian states—now organized under the Alliance of Sahel States (AES)—advocates for a sovereign approach to mining revenues.
For Niger, diversifying export markets is a strategic imperative. Potential buyers now include Russia, China, Turkey, and several Gulf nations, all of which have been mentioned as prospective partners for Sahelian strategic minerals. Uranium from Niger, which has supplied roughly one-fifth of the European Union’s nuclear fuel needs in recent years, may see its supply chains fundamentally reshaped. Existing long-term contracts with EDF and other European utilities will need to be reassessed under this new framework.
The economic implications are equally critical. Uranium has long faced criticism for contributing relatively little to Niger’s public finances. However, with direct state management, TSUMCO could unlock higher margins—provided it secures solvent markets and maintains tight operational cost controls. In the short term, ensuring continuous production, preserving local employment, and upholding radiation safety standards at the site remain the most pressing operational priorities.
This development highlights the depth of the ongoing geoeconomic repositioning across Central Sahel. Beyond symbolism, the creation of TSUMCO commits Niger to a demanding path where declared sovereignty must translate into tangible industrial performance.
