Southern Rukwa Helium Project Update

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, provides an update on the Company's southern Rukwa Helium Project.

Commencement of Electrical Submersible Pump ("ESP") Testing at ITW-1

Following the completion of wireline logging and the full mobilisation of equipment and personnel to site, the Company is pleased to announce that the ESP testing phase has commenced at the ITW‑1 well.  

All downhole tools and surface control equipment has now undergone the required checks and verification procedures prior to deployment. The ESP assembly is running in hole and will be positioned to allow further evaluation of the fractured Basement and Karoo intervals, through increased flow rates and enhanced helium production from these deeper geological zones.  

Once the ESP is set at the designated depth and the tubing hanger has been successfully tested, a final function test will be carried out before the well is opened and the pump activated. It is anticipated that this testing phase will take two to three weeks to complete.

The Company will provide further updates as operations progress.

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. With an expanding global footprint, the Company 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 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 production in Q4 2025, with further wells coming onstream in 2026 for both helium and CO₂ production.
