PROJECTS

Our Nemaha Project in Kansas, USA, is prospective for hydrogen and helium.

HyTerra is leading the way in the world’s best geological hydrogen hotspot.

Nemaha is located between Kansas City and Wichita in the centre of a major industrial and manufacturing hub. The project can be connected via railways, roads, and pipelines to a long list of potential offtakers nearby including ethanol and ammonia manufacturers, and petrochemical plants.

Early drilling results demonstrate the presence of a working hydrogen and helium system.

HyTerra’s 100% owned and operated leases cover over 80,000 acres above the hydrogen-generating Mid-Continental Rift system.

Flagship Nemaha Project (Kansas) well sampling results show high concentrations of hydrogen up to 96% and helium up to 5%*.

Geneva Project (Nebraska) well testing results show hydrogen concentrations up to 44% and helium up to 13%^.

Leases are surrounded by important ammonia/fertilizer and helium production plants in the United States.

Kansas imports anhydrous ammonia from other U.S. states but is the USA’s largest helium producer.

Nemaha is at the centre of a major industrial and manufacturing hub.

The majority of hydrogen today is used in oil refining, ammonia production, and methanol production.

Over 35% of US ammonia is produced in Kansas and neighbouring states, presenting HyTerra with major multiple commercialisation opportunities. In time, hydrogen’s unique properties could see it emerge as an attractive, low-cost, clean energy source for transportation, steel and cement production, energy storage and power generation.

White hydrogen. An abundant natural source.

White hydrogen is naturally occurring and, as such, could have much lower production costs and carbon emissions than hydrogen separated from natural gas or from water electrolysis.

At HyTerra’s Nemaha Project, rainwater seeps underground where it reacts with iron-rich rocks at elevated temperatures to make hydrogen (H2).

White hydrogen is brought to surface using conventional oil and gas techniques, and as an energy-dense, low carbon fuel source, it has the potential to revolutionise industry and economies worldwide.

Nemaha is also prospective for helium, a vital input for many technologies.

Helium is an irreplaceable input for many important technologies, with significant demand from manufacturers of semi-conductors to MRI’s.

A historic well drilled in 2009 at our Nemaha Project, Sue-Duroche-2 returned a helium occurrence of 3%*. The economic threshold for a helium-rich fields in U.S. is 0.3% for primary production.

Liquid helium sells at up to 50 times the price of LNG. Current prices are US$450/thousand standard cubic feet.

HyTerra continues to explore high-grade areas of significant helium potential.

^H2 + He % reflects occurrences of published gas analyses recovered from the wellbore. Uncertainty remains on historic well operations, sampling techniques, and analyses. The values are considered up to a % of H2 or He.

Company Profile

Our Geneva Project in Nebraska, USA, is targeting white hydrogen and helium.

HyTerra has a 16% interest (and the right to earn up to 51%) in a Joint Development Agreement with Natural Hydrogen Energy LLC for the Geneva Hydrogen Project near the town of Geneva in Nebraska, USA.

Drilled to 11,200ft (3,400m) in 2023, a wildcat well (Hoarty NE3) specifically targeted white hydrogen and was situated on the margin of a mid-continental rift. Elevated hydrogen was detected during drilling and gas was flared during swab testing.

The Company received gas composition data from Joint Development Agreement partner Natural Hydrogen Energy LLC (NH2E) in December 2024 and after independent review, HyTerra and NH2E reached a consensus that these analyses are valid in a joint meeting in March 2025.

Further assessment or appraisal operations (e.g. a new testing program due to the failure of the ESP) would be required to understand the potential for commercial hydrogen and/or helium production from this well. Discussions will continue with NH2E on the path forward for this venture.
