Helix Exploration Confirms Geological Hydrogen Potential at Rudyard Project

Helix Exploration PLC has reported breakthrough results from its Rudyard Project, confirming significant potential for geological hydrogen generation.

An independent study has verified the presence of hydrogen-generating minerals in rock cuttings from the project area. Isotope analysis revealed a ³He/⁴He ratio of 0.74 Rₐ, representing an increase of more than 3,600% above average continental crust values (0.02 Rₐ). The analysis also found Helium-3 concentrations exceeding 10 parts per billion (ppb) on average.

Highlights

· Elevated Helium-isotope Signature: Analysis from the Rudyard Project recorded a consistent ³He/⁴He ratio of 0.74 Rₐ, over 3,600% above average continental-crust values (0.02 Rₐ), representing some of the highest recorded in continental North America outside of Yellowstone, with Helium-3 concentration averaging greater than 10 ppb.

· Confirmed Mantle Contribution and Geological Implications: Isotopic modelling suggests roughly 9% of Rudyard’s helium originates from the mantle. This deep-Earth connection not only replenishes helium within the reservoir but also facilitates the water-rock reactions that generate natural hydrogen at depth – a key indicator of Rudyard’s long-term potential as both a helium and hydrogen source.

· Hydrogen Potential: Geochemical results establish Rudyard as one of the few verified hydrogen-prone ultramafic systems in North America and has the potential to produce some of the world’s cleanest hydrogen with zero CO₂ emissions.

Isotopic modelling indicates that approximately 9% of Rudyard’s helium is derived from mantle sources, highlighting the potential for active geological hydrogen generation in the subsurface environment.

Helix Exploration PLC said the findings support its view that Rudyard could produce some of the world’s cleanest hydrogen, with zero CO₂ emissions, aligning with the U.S. Department of Energy’s target to reduce clean hydrogen production costs to $1 per kilogram.

These results mark a major milestone in the company’s strategy to advance natural hydrogen exploration and development in the United States.
