HyTerra Spuds Second Well at Nemaha Project, Targeting New Hydrogen Play in Kansas

HyTerra (ASX: HYT) has commenced drilling operations at its Blythe 13-20 well, located in the company’s 100%-owned Nemaha Project in Kansas. The well was spudded on May 20th using the same rig and crew as the recently drilled Sue Duroche 3. Blythe 13-20 targets a new geological play near the historic Scott-1 well, which recorded hydrogen concentrations of up to 56%.

The well aims to drill both sedimentary and Precambrian basement formations, collect rock and gas samples, and evaluate the potential for subsurface hydrogen and helium accumulations. It lies within 6,860 net acres of HyTerra’s leasehold and was chosen based on airborne gravity and magnetic survey interpretations. If successful, HyTerra may drill a third well in the ongoing campaign.

This marks the second of two back-to-back wells in a 12-month exploration program funded by Fortescue Future Industries. Results from the drilling, sampling, and wireline logging are expected within 3–4 weeks. The company continues to position itself as a leading player in natural hydrogen exploration in the U.S.

ASX RELEASE

Drilling Commenced at Blythe 13-20

• Blythe 13-20 well spudded on May 20th Kansas time using the same Murfin Rig 116 rig and crew
• The well is targeting a new geological play within HyTerra’s 100% owned and operated Nemaha Project acreage
• Blythe 13-20 location is proximal to the Scott-1 well (1982) which reported hydrogen concentrations of up to 56% in the sedimentary section
• There remains an option to drill a third well in this drilling campaign at the Company’s discretion

HyTerra Limited (ASX: HYT) (HyTerra or the Company) has two firm wells in the drilling sequence which began in April 2025 at the Nemaha Project in Kansas, USA. These wells are the first steps for the Company in executing a comprehensive 12-month exploration work program designed to unlock the potential of natural (white) hydrogen in Kansas through its 100% owned and operating subsidiary HYT Operating LLC. This exploration program funding is sourced from the recent investment in the Company by Fortescue Future Industries Technologies Pty Ltd.

Drilling Update

The Company is pleased to announce that Blythe 13-20 spudded on May 20th Kansas time. Blythe 13-20, approximately 50 km southwest of Sue Duroche 3, is the second of the two firm back-to-back wells which are located next to historical occurrences of hydrogen as part of the Exploration Stage I program. There remains an option to drill a third well at the Company’s discretion.

The objectives of the Blythe 13-20 well are:

• Drill both the sedimentary and Pre-Cambrian basement sections
• Confirm the presence and concentrations of hydrogen and/or helium in the subsurface formations (via mud gas log readings and surface mud gas samples sent to independent laboratories for analysis)
• Evaluate the quality and characterise the reservoir rocks (detailed wireline logs and rock sampling)

Blythe 13-20 well will test a new geological play in the Company’s acreage. The well site is located around 1,400m east of the historic Scott-1 well drilled in 1982, which reported hydrogen concentrations of up to 56% in the sedimentary section. The drilling, logging, and sampling program is expected to take between 3–4 weeks as the planned total depth (TD) is projected to be deeper than the Scott-1 well. The Company has 6,860 net acres in close vicinity to the well site.

The prospect is supported by interpretation of the airborne gravity gradiometry and magnetic survey acquired by Xcalibur Multiphysics for HyTerra in 2023. If drilling results are encouraging, the Company will progress towards monitoring of pressure and gas composition of the well, similar to Sue Duroche 3.

Murfin drilling rig 116 arrived at the Blythe 13-20 well site with the same crew as was on the Sue Duroche 3 site. As key well results are received, the Company will inform the market accordingly.

HyTerra. A World of Opportunity.
Exploring for natural hydrogen and helium resources near major industrial hubs. HyTerra was the first company to list on the ASX with a focus on white hydrogen, which is generated naturally by the Earth. White hydrogen potentially has much lower production costs and carbon emissions than man-made hydrogen.

Our Nemaha Project in Kansas, USA, holds 100% owned and operated leases across the emerging Nemaha Ridge natural hydrogen and helium play fairway. Our Geneva Project in Nebraska, USA, is a 16% earn-in interest in a Joint Development with Natural Hydrogen Energy LLC targeting natural hydrogen and helium. Both projects could be connected via existing transport infrastructure to multiple nearby off-takers, including ammonia manufacturers, and petrochemical plants.

Important Risk Commentary:
It is important to note that there remains both geological and potential development risks with these projects and the Company’s commercial and business objectives. This is an emerging frontier with the potential to unlock significant low-carbon hydrogen gas supplies but with equally significant risk and uncertainty. Key risks include the presence, concentrations, recovery, and commercial potential of both hydrogen and helium gases. For more information on risks please refer to the ASX release ‘Entitlement Issue Prospectus’ on April 8th, 2024: https://wcsecure.weblink.com.au/pdf/HYT/02793318.pdf.
