**Fusion Fuel Highlights Announced Exploration Plan at Jaguar Uranium's Huemul Project, Potential Royalty Portfolio Income**

*Planned acquisition of controlling interest in Royal Uranium expected to provide Fusion Fuel with 1.0% NSR royalty exposure to Huemul Project, Part of Argentina's Historic Critical Metals Mining District*

 

Dublin, Ireland, April 20, 2026 (GLOBE NEWSWIRE) - Fusion Fuel Green PLC (NASDAQ: HTOO) ("Fusion Fuel" or the "Company"), a leading provider of full-service energy engineering, advisory, and utility solutions, today highlighted potential royalty income tied to the 1.0% net smelter return ("NSR") royalty held by Royal Uranium Inc. ("Royal Uranium") on the Huemul Project, a 27,700-hectare uranium-copper-vanadium district in Mendoza Province, Argentina, centered on Argentina's first-ever producing uranium mine.

Through Fusion Fuel's previously announced planned acquisition of a controlling interest in Royal Uranium, the Company expects to gain capital-efficient royalty exposure to potential future production from the Huemul Project.

As <u>announced</u> by Jaguar, the Huemul Project is situated within the Province of Mendoza, Argentina. Spanning 27,700 hectares, the project represents a district-scale exploration and past-producing asset anchored by the historic Huemul mine, which operated from 1955 to 1975 under Argentina's Comisión Nacional de Energía Atómica (CNEA), processing approximately 130,000 tons of ore and historic head grades of 0.21% uranium, 2.0% copper, and 0.11% vanadium. Production is believed to have ceased in the mid-1970s due in part to low uranium prices.

Jaguar has outlined a two-phase exploration plan for the Huemul Project. Exploration activities are expected to commence following Jaguar's anticipated submission and approval of an environmental baseline study, subject to applicable regulatory approvals.

Fusion Fuel believes that Jaguar's announced exploration plan would further support the long-term value potential of its anticipated royalty platform. Through its anticipated interest in Royal Uranium, Fusion Fuel believes it will gain capital-efficient exposure to exploration and development activity across multiple projects.

Under the NSR royalty structure, Fusion Fuel would be entitled to receive a percentage of revenue from mineral production, net of certain deductions. Fusion Fuel believes this structure aligns with its strategy of building a diversified, capital-efficient royalty platform with exposure to critical energy and resource markets.

"The announced exploration plan of Jaguar at the Huemul Project is anticipated to represent an important step in advancing a broader portfolio of critical mineral assets that we expect to have potential exposure to through our planned acquisition of Royal Uranium," said John-Paul Backwell, Chief Executive Officer and Chairman of Fusion Fuel. "As global demand for uranium and other critical minerals continues to accelerate, we believe our strategy of building a diversified, capital-efficient royalty platform may position Fusion Fuel to benefit from potential long-term commodity upside."

Fusion Fuel previously announced that it entered into a Share Exchange Agreement, dated February 18, 2026 (the "Share Exchange Agreement"), to acquire a controlling interest in Royal Uranium as part of its strategy to establish a diversified energy commodity royalty platform with exposure to critical energy resources, including uranium and natural gas. A further description of the terms and conditions of the proposed transaction has been disclosed in a Form 6-K/A furnished with the U.S. Securities and Exchange Commission (the "SEC") on February 18, 2026.
