Helium One Global Ltd

("Helium One" or "the Company")

Further Sale Under Helium Offtake Agreement

Helium One Global (AIM: HE1), the primary helium explorer in Tanzania with a 50% working interest in the Galactica-Pegasus helium development project in Colorado, USA, notes the Blue Star Helium (ASX:BNL) ("Blue Star" or "Operator") announcement issued today regarding the Galactica Project, and replicated below.

Operator Reported Highlights

•          The Operator has delivered its third helium trailer from the Pinon Canyon Plant on schedule, with a fourth trailer on site and being filled

•         Continued increases in helium output are expected toward the plant's full design capacity, driven by planned production work, including debottlenecking the plant and gathering system, drilling additional development wells and deepening of existing wells

The Operator advises that a third tube trailer of helium from the Pinon Canyon Plant at its Galactica Project in Las Animas County, Colorado has been delivered to the offtaker. A fourth tube trailer is on site and being filled. Trailer exchanges continue to proceed on a scheduled basis, consistent with previous announcements.

With this delivery confirming regular trailer fills are now proceeding on a scheduled basis, the Company may not announce each trailer exchange but will continue to announce significant milestones and commercial developments.

Notes to Editors

Helium One Global, the primary helium explorer in Tanzania with a 50% working interest in the Galactica-Pegasus helium development project in Colorado, USA. The Company holds helium licenses within two distinct helium project areas, across two continents and has the potential to become a strategic player in resolving a supply-constrained helium market.

The Company's flagship southern Rukwa Project is located within the southern Rukwa Rift Basin in south-west Tanzania. This project is entering a full appraisal and development stage following the success of the 2023/24 exploration drilling campaign, which proved a helium discovery at Itumbula West-1 and, following an extended well test ("EWT"), successfully flowed 5.5% helium continually to surface in Q3 2024.

Following the success of the EWT, the Company filed a Mining Licence ("ML") application with the Tanzania Mining Commission in September 2024 and the 480km² ML was formally awarded to the Company in July 2025.

The Company also owns a 50% working interest in the Galactica-Pegasus helium development project in Las Animas County, Colorado, USA. This project is operated by Blue Star Helium Ltd (ASX: BNL) and successfully completed a six well development drilling campaign in H1 2025. The completion of the development programme is a key component of the broader Galactica-Pegasus development strategy; aimed at progressing the helium and CO₂ discoveries to near-term commercial production.

This programme has seen a systematic approach to developing the extensive Lyons Formation reservoir. The programme has delivered encouraging results, in line with expectations, consistently encountering good helium (up to 3.3% He) and CO₂ concentrations in the target formation and demonstrating promising flow potential. The initial Galactica wells were tied into first gas in Q4 2025, with further wells coming onstream in 2026 for both helium and CO₂ production.
