HyTerra Ltd (ASX:HYT) has withdrawn from its Joint Development and Earn-in Agreement with Natural Hydrogen Energy LLC over the Geneva Project in Fillmore County, Nebraska, and is concentrating technical effort and capital on the Kansas Rift Play, the company disclosed on 10 November 2026.
Key Points
- HyTerra has withdrawn from the Nebraska JDA with NH2E, forfeiting its 16.03% interest in the Geneva Project and the US$2.67 million funded to date, with no further funding obligations remaining.
- The Kansas Rift Play underlies more than 80% of HyTerra's Kansas acreage and is the priority for technical work and capital within the existing portfolio.
- RISC Advisory has been engaged to independently audit prospective hydrogen and helium resources across HyTerra's Kansas lease holding, with completion targeted for Q4 2026.
- Drilling at the Larson 1-14 target has been deferred, with HyTerra targeting a return to drilling on Larson 1-14 or a higher-ranked target during the 2027 drilling season.
Nebraska JDA Withdrawal Terms and Financial Impact
HyTerra, through its wholly owned subsidiary Neutralysis Industries Pty Ltd, had been earning into the Geneva Project in Fillmore County, Nebraska under the JDA with NH2E. The company funded US$2.67 million under the agreement, earning a 16.03% interest in the project. Completing the earn-in would have required a further US$17.33 million across two phases. The Board concluded that continuing to earn in on those terms was not the best use of the company's capital. As a result of withdrawal, HyTerra will not retain any interest in the project and will not recover the amounts funded to date.
Kansas Rift Play Technical Program and RISC Advisory Audit
The Kansas Rift Play underlies more than 80% of HyTerra's Kansas acreage and is described in the filing as closer to the interpreted Midcontinent Rift source rocks than the Ridge Play wells drilled to date. Production testing at McCoy-1 highlighted the importance of proximity to demonstrated hydrogen source rocks, a factor now given greater weight in the company's exploration approach. Laboratory analyses are demonstrating hydrogen generation from selected Midcontinent Rift rock samples under laboratory conditions. RISC Advisory has been engaged to audit prospective hydrogen and helium resources, including stimulated hydrogen, across the Kansas lease holding, with the audit targeted for completion in Q4 2026.
Larson 1-14 Drilling Deferred to 2027 Season
Larson 1-14 was identified earlier in 2026 as a high-ranked Rift Play target, with drilling previously targeted for October 2026 subject to funding availability and execution of a rig contract. Recent technical work has identified additional targets in the Rift Play, and the company is now completing a technical program to rank and characterise all Rift Play targets before committing capital. Larson 1-14 remains permitted. No further appraisal of McCoy-1 and no additional Ridge Play drilling is planned while the Rift Play technical program is completed. New US and international opportunities continue to be assessed under Pillars 2 and 3 of the company's Strategic Plan, with technical evaluation advancing in Oman with ARA.
