HyTerra Ltd (ASX:HYT) is an Australian-listed, globally active exploration company focused on geologic hydrogen — naturally occurring hydrogen produced from subsurface geological processes. The company is exploring the Nemaha Project in Kansas, USA, across two distinct geological play types: the Ridge Play (on the Nemaha Ridge) and the Rift Play (across the Mid-Continent Rift). HyTerra's commercial objective is to establish a viable geologic hydrogen project, which could provide an alternative Supply of natural hydrogen for energy applications. The company also holds an OTCQB listing and a Frankfurt Exchange listing.

What the Company Does

HyTerra explores for and aims to develop geologic hydrogen — hydrogen generated naturally in the subsurface through serpentinisation, radiolysis, or other geological processes. Unlike green hydrogen produced by electrolysis or blue hydrogen produced from Natural Gas with carbon capture, geologic hydrogen (sometimes called gold hydrogen or white hydrogen) occurs naturally in geological formations and may be produced without the energy-intensive processes required for manufactured hydrogen.

The company's Nemaha Project in Kansas covers two geological plays. The Ridge Play targets hydrogen that may have migrated from the Mid-Continent Rift to the CREST of the Nemaha Ridge. The Rift Play — covering more than 80% of HyTerra's Kansas acreage — targets hydrogen closer to the Mid-Continent Rift source rocks, which are iron-rich formations shown in laboratory testing to generate hydrogen.

HyTerra has been advancing both plays simultaneously, with McCoy-1 testing the Ridge Play and the Larson 1-14 drill target maturing as a potential Rift Play well, subject to funding availability and rig contract.

Financial and Operational Performance

According to HyTerra's ASX announcement dated 4 August 2026, production testing of the first zone at McCoy-1 in the Ridge Play was completed on schedule, below budget, and without any health, safety, or environmental incidents. The 14-day production test of the first zone recorded an estimated gas flow rate of approximately 0.1 Mscf/d at the conclusion of testing.

Onsite gas measurements detected hydrogen, helium, methane, and nitrogen. An elevated helium concentration of 2.8% on an air-corrected basis was recorded at the conclusion of the test, consistent with laboratory data from gas samples collected while swabbing the well in 2025. Preliminary interpretation indicates that gas saturation was low in the tested interval.

Due to the low gas saturation result, the second zone test will not proceed at McCoy-1 at this stage. HyTerra stated it will integrate the test results and determine appropriate next steps for McCoy-1 and the broader Ridge Play. The company emphasised that McCoy-1 tests one location within the Ridge Play and that its broader portfolio across different play types provides multiple pathways toward a commercial project.

Key Factors Shaping the Business

The elevated helium concentration of 2.8% is a noteworthy result. Helium is associated with geologic hydrogen production environments and its presence at elevated concentrations confirms that the geological environment at the Nemaha Ridge is producing noble gases consistent with the hydrogen generation model. However, gas saturation was assessed as low in the tested interval, limiting the practical significance for flow rate purposes at this location.

The Rift Play is gaining prominence as a result of the McCoy-1 test. With the Ridge Play demonstrating the presence of relevant gas but low saturation at the tested location, the Rift Play — targeting hydrogen closer to the Mid-Continent Rift source rocks — becomes a more important component of HyTerra's portfolio. The Larson 1-14 target in the Rift Play has been identified and a drill permit obtained, representing the next potential well location.

Operational and technical learnings from McCoy-1 are described as valuable. The test provided new reservoir data and "Must Haves" rulebook refinements that will inform future prospect selection, well design, and testing programs. This framework approach to geologic hydrogen exploration reflects the novelty of the sector and the need to develop bespoke technical criteria.

Risks and What to Watch

Geologic hydrogen exploration is an emerging and largely unproven commercial sector. While natural hydrogen occurrences have been documented globally, commercially viable geologic hydrogen projects are at a very early stage of development worldwide. The technical, economic, and regulatory frameworks for commercial geologic hydrogen production are not yet established, creating uncertainty about development pathways.

The McCoy-1 result at low gas saturation — while providing technical learnings — does not represent a commercial discovery. The company must identify and test additional locations with higher gas saturation to demonstrate the commercial potential of its acreage. The Rift Play at Larson 1-14 represents the next potential data point, but is subject to funding and rig availability.

Funding availability is a key constraint for HyTerra. As a pre-revenue exploration company, HyTerra relies on Capital Markets to fund its exploration programs. The pace of portfolio advancement — including the Larson 1-14 Rift Play well — will be limited by available funding.

Key Takeaways

HyTerra completed production testing at McCoy-1 in the Ridge Play of the Nemaha Project in Kansas, recording elevated helium of 2.8% on an air-corrected basis but low gas saturation in the tested interval, resulting in a flow rate of approximately 0.1 Mscf/d. The second zone test will not proceed at this stage. The company has gained technical and operational learnings that will inform future exploration activities, particularly for the Rift Play — which covers more than 80% of HyTerra's Kansas acreage and targets hydrogen closer to Mid-Continent Rift source rocks. Determination of next steps for McCoy-1 and the Rift Play, including Larson 1-14 (subject to funding), are the key near-term activities to watch.
