Fusion Fuel Green PLC Provides Update on Royal Uranium Royalty - EIA Permit Obtained for Laguna Salada Uranium Project, a 2.0% NSR Asset

Dublin, March 03, 2026 (GLOBE NEWSWIRE) -- Fusion Fuel Green PLC (NASDAQ:HTOO) (“Fusion Fuel” or the “Company”), an integrated energy company, today announced that a key regulatory milestone has been achieved at the Laguna Salada Uranium Project in Chubut Province, Argentina, an asset on which Royal Uranium Inc. (“Royal Uranium”) holds a 2.0% net smelter returns (“NSR”) royalty.

As recently disclosed by Jaguar Uranium Corp. (NYSE: JAGU), the operator of the Laguna Salada Project, the Provincial Ministry of Environment of Chubut Province, Argentina, has granted an Environmental Impact Assessment (“EIA”) permit for exploration activities at the “Guanaco” concession portion of Laguna Salada. The permit, received ahead of schedule, authorizes geophysical surveys, surface sampling, trenching, drilling, access road construction, and related exploration infrastructure. Jaguar Uranium believes Laguna Salada represents a near surface, bulk exploration and development target and will now accelerate its fully funded "Phase 1" exploration campaign to test this thesis, following its recent $25 million IPO earlier this year.

Royal Uranium holds a 2.0% NSR royalty covering the Guanaco concession portion of the Laguna Salada Project. An NSR royalty entitles the holder to receive a percentage of gross revenue from mineral production, net of certain permitted deductions, without bearing capital or operating costs.

Background on Royal Uranium Transaction

On February 18, 2026, Fusion Fuel announced that it had entered into a definitive share exchange agreement (“Share Exchange Agreement”) to acquire a controlling interest in Royal Uranium, a private royalty company holding a diversified portfolio of royalties across the Americas. The proposed transaction is intended to provide Fusion Fuel with exposure to energy commodity royalties from certain assets, particularly uranium and natural gas deposits, through a capital-efficient royalty portfolio.

Implications of the EIA Milestone

The EIA permit represents a meaningful regulatory step that enables expanded exploration activities at Laguna Salada.

For Royal Uranium, the development:

• Advances a royalty-bearing asset within its portfolio toward potential future development;
• Reduces permitting uncertainty associated with near-term exploration activities; and
• May accelerate project timelines, depending on operator execution and exploration results.
  
  

For Fusion Fuel, subject to the closing of the previously announced Royal Uranium acquisition:

• Demonstrates progress within the underlying royalty portfolio;
• Highlights the potential value embedded in the royalty assets portfolio; and
• Reinforces the Company’s strategy of gaining diversified exposure to critical energy commodities without direct mining operations or development capital expenditures.
  
  

While EIA approval authorizes exploration activities and does not ensure commercial production, continued advancement of the project could, if successful, ultimately result in royalty payments tied to future uranium production.
