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. The 480km² ML has now been offered to the Company and was officially accepted in March 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 has 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 next steps will see the Galactica wells tied into initial production in Q4 2025.

Helium One is listed on the AIM market of the London Stock Exchange with the ticker of HE1 and on the OTCQB in the United States with the ticker HLOGF.
