Argentina possesses 34,250 tonnes of identified recoverable uranium resources, with exploration data suggesting sufficient domestic supply for over 40 years of internal demand. Driven by the Javier Milei administration’s Nuclear Plan presented in June, the South American nation is reviving its atomic sector to secure energy independence and export critical minerals.
The Bottom Line
- Resource Depth: Identified reserves stand at 34,250 tonnes, capable of fueling the country’s three operational nuclear reactors for more than four decades.
- Regulatory Push: The Argentine government’s newly introduced Nuclear Plan targets both local self-sufficiency and high-value mineral exports.
- Infrastructure Parallel: Surging production in the Vaca Muerta shale formation—hitting a record 916,200 barrels per day in July—serves as the operational blueprint for reviving extractive energy sectors.
Mapping Argentina’s Uranium Reserves and Production Pipeline
For more than three decades, Argentina remained dormant in uranium extraction. Historical production occurred in Mendoza province at the Huemul mines between 1955 and 1975, and Sierra Pintada from 1975 until 1997. Since then, the country has relied entirely on imports to feed its three nuclear power plants, which currently account for 7 % of the nation’s electricity generation.
That dependency is shifting. According to Mario Capello, a mining engineer and former undersecretary of Mining Development, the country holds reasonably assured resources to cover domestic requirements for 41 years. Furthermore, incorporating inferred resources pushes total potential to nearly 35,000 tonnes, which stretches theoretical domestic reactor demand to 140 years.
Here is the math: global interest in critical minerals has fundamentally altered project economics. Ignacio Celorrio, former president of the Argentine Chamber of Uranium Companies and partner at Martínez de Hoz & Rueda (MHR), notes that rising global pricing has revived long-dormant exploration assets across the country.
Regulatory Frameworks and Corporate Backing
The Secretaría de Minería reports a portfolio of 21 uranium projects spread across Chubut, Mendoza, Neuquén, Río Negro, Salta, and Santa Cruz. The state-controlled Comisión Nacional de Energía Atómica retains majority oversight, holding reactivation plans for Sierra Pintada in Mendoza and Cerro Solo in Chubut.
Private and provincial entities are also staking claims. Sophia Energy, the British UrAmerica, and Santa Cruz provincial firm Fomicruz hold operational rights, while Integra Tierras Raras and Edhipsa recently applied for exploration permits in Río Negro. Yet, the most advanced developments belong to Canadian miners holding preliminary economic assessments.
Jaguar Uranium is advancing the Laguna Salada project in Chubut alongside efforts to restart the Huemul mine. The firm hired retired U.S. Army General Charles Flynn as a strategic advisor to engage the White House, aiming to align its South American assets with U.S. critical mineral security priorities. Meanwhile, Blue Sky Uranium—backed by Argentine conglomerate Corporación América—operates the Ivana-Amarillo Grande project in Río Negro.
| Project Name | Location | Primary Stakeholder / Backer | Project Status |
|---|---|---|---|
| Laguna Salada / Huemul | Chubut / Mendoza | Jaguar Uranium | Preliminary Economic Assessment / Reactivation Phase |
| Ivana – Amarillo Grande | Río Negro | Blue Sky Uranium / Corporación América | Preliminary Economic Assessment Advanced |
| Sierra Pintada | Mendoza | Comisión Nacional de Energía Atómica | Reactivation Pipeline |
| Cerro Solo | Chubut | Comisión Nacional de Energía Atómica | Exploration & Development Pipeline |
Industrial Integration and the Vaca Muerta Blueprint
Beyond raw mineral extraction, the Milei administration’s framework encourages industrial processing before export. Andrés Villarreal, a mining specialist and partner at MHR, emphasizes that the strategy marries local energy security with broader global supply chains driven by the energy transition.
Domestic demand could also expand via advanced manufacturing. In July, Meitner Energy—backed by domestic and U.S. capital—announced an initiative to build a modular nuclear reactor inside the country, with an investment of 1,200 million dollars. This integration mirrors the trajectory of Argentina’s oil sector.
Data from the Ministry of Economy confirms that July petroleum extraction hit a record of 916,200 barrels per day, a substantial increase compared to the previous period. Unconventional extraction from the Vaca Muerta formation in Neuquén drove 70% of that total, reaching 643,100 barrels daily. While uranium extraction requires vastly different capital expenditure and regulatory navigation, policymakers intend to replicate the hydrocarbons sector’s export momentum.
