HyTerra Reports High Helium Concentrations at Blythe 13-20 Well in Kansas

HyTerra Limited (ASX: HYT) has announced unexpectedly high helium concentrations of up to 4.4% in mud gas samples from its Blythe 13-20 well, part of the company’s Nemaha Project in Kansas. Hydrogen concentrations peaked at 16.5%, reinforcing the region’s potential as a significant natural hydrogen and helium province.

The discovery marks an important milestone, extending the known helium play in Eastern Kansas and positioning HyTerra at the forefront of exploration in this emerging frontier.

Blythe 13-20 was drilled to a depth of 5,300 ft on time and on budget. Extensive data collection, including mud gas logging, wireline logging, and cuttings analysis by Schlumberger, underpins the promising results. The well sits strategically between the Mid-Continent Rift and Nemaha Ridge, a zone considered favorable for gas migration pathways.

HyTerra plans to convert Blythe 13-20 into an appraisal well, installing downhole monitoring equipment to assist in designing an initial testing program after additional wells are drilled.

This campaign is funded by Fortescue Future Industries, and the company is preparing to drill the McCoy 1 well to further test the system’s scale.

Kansas is already a major helium producer in the U.S., and these findings strengthen HyTerra’s position in a market critical for semiconductors, aerospace, and medical applications.

High Concentrations of Helium Found in Blythe 13-20
 
Highlights

• Unexpectedly high helium concentrations of up to 4.4% were recorded in mud gas samples at Blythe 13-20, a level not previously observed in this part of Kansas. Hydrogen concentrations peaked at 16.5%.
• Extends the Helium play in Eastern Kansas from the Sue Duroche 3 area significantly.
• Helium is critical to future-facing industries including semiconductors, aerospace, MRI technology, and quantum computing, with no viable substitutes due to its unique inertness and cryogenic properties.
• Kansas is the leading producer of helium in the US with decades of continued production from the Hugoton natural gas field with concentration ranges of 0.25 to 2.5% helium.
• Blythe 13-20 will now be converted to an appraisal well in coming weeks to clean the well up and install downhole monitoring equipment to provide information to assist in the design of an initial testing program planned to be after the wells have been drilled and the subsurface data has been analysed.

HyTerra Ltd (ASX:HYT) has increased the firm wells in the drilling sequence to a total of three wells drilled from April through July 2025 at the Nemaha Project in Kansas, USA. This exploration program funding is sourced from an investment in the Company by Fortescue Future Industries Technologies Pty Ltd.

Avon McIntyre, Executive Director says “The discovery of high helium concentrations in an area previously untested for this potential is a highly encouraging result. While hydrogen concentrations peaked at 16.5%, lower than historical highs nearby, additional data will be acquired as we proactively monitor the well downhole. This well is located at a midpoint between the Mid-Continent Rift and the Nemaha Ridge, and we may have drilled into a helium and hydrogen migration pathway between these two main features. Now we move away from twinning historic wells to drill McCoy 1 on the crest of the Nemaha Ridge to further unlock the broader potential of this system”.
