("Helium One" or "the Company")

First Helium Sold from Pinon Canyon Plant

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 first production tube trailer has been sold and now left the Pinon Canyon Plant, concluding the early production commissioning and optimisation phase

•         Pinon Canyon Plant uptime and production fill rates have increased recently, following longer phases of steady-state operation

•             A new tube trailer under the offtake agreement announced on 4 June 2026 is now on site and being filled

•      Ongoing helium output growth is expected to be driven by planned production ramp-up, including debottlenecking of the plant and gathering system, drilling of additional development wells and deepening of existing wells to increase flow

Helium One CEO, Lorna Blaisse, commented:

"This represents a significant milestone for Helium One, with the Company now generating its first revenues from the Galactica-Pegasus joint venture project. This achievement validates our strategic decision to diversify our portfolio and provides an important foundation for future growth. We are pleased to continue working closely with Blue Star Helium as the Joint Venture progresses its development plans, including further drilling and additional revenue generation."

Production and Delivery Status Reported by the Operator

Following completion of early production commissioning and optimisation phase, the Pinon Canyon Plant has recently seen substantially increased uptime and longer phases of steady-state operation. It is now demonstrating routine runtime, shut-in and restart cycles more characteristic of the expected long-term operational profile.

With the recent acceleration in uptime and helium output, production fill rates have increased significantly, and the first tube trailer under an early production spot sales arrangement has now left site. The second tube trailer (and the first under the 3-month fixed price offtake agreement announced on 4 June 2026) is now on site and being filled.

As plant and gathering system refinement continues, and in line with development planning for this stage of ramp-up, the Operator is looking at the potential to deepen existing wells to expose more reservoir and further increase flow. Consistent with original development planning, and subject to permit approval, the Operator plans to drill three new wells for tie-in to the Pinon Canyon Plant during H2 2026, which are expected to further increase raw gas throughput and helium product output.

 Operator Reported Current Helium Market

The North American helium market continues to exhibit strong pricing fundamentals, driven by sustained, structural demand across high-technology manufacturing sectors, particularly semiconductor fabrication, aerospace engineering, and advanced defence technologies. The global helium market continues to be affected by structural supply chain disruptions, rationing and surcharges, particularly resulting from prolonged instability in Middle Eastern supply routes, which has materially increased demand for reliable, US-sourced domestic supply.

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.
