Helium One Global Ltd Announces Jackson-27 Flow Test Results & Gas Analysis Update
Helium One Global reports significant progress at its Galactica-Pegasus helium project in Colorado, where the Jackson-27 well has achieved impressive flow test results. The well, reaching a total depth of 1,183 feet, demonstrated natural flow rates exceeding 320 thousand cubic feet per day (Mcfd), with projected stabilized rates between 350-450 Mcfd and a maximum potential of 550 Mcfd.
Key findings include:
- Helium concentration up to 0.41% (air-corrected)
- 98.31% CO2 content
- High-quality gas-saturated Lyons Sandstone Formation
- Strong pressure build-up indicating good reservoir communication
The company holds a 50% working interest in the project, operated by Blue Star Helium. This development follows Helium One's recent success in Tanzania, where they secured a Mining License in March 2025 after proving a helium discovery at Itumbula West-1 with 5.5% helium flow to surface.

Highlights
Jackson-27 flowed naturally during drilling and at Total Depth ("TD")
Flow rate since TD has increased to over 320 thousand cubic feet per day ("Mcfd")
Projected stabilised flow rates are 350 Mcfd to 450 Mcfd, constrained to optimise production, with a maximum potential rate of 550 Mcfd
Early samples return helium concentration of up to
0.41% (air-corrected) and98.31% CO2
Details
The Jackson-27 well reached TD at 1,183 feet (361m) within the Upper Lyons Formation, encountering the Lyons Sandstone Formation at 1,123 feet (342m). As expected, water was not encountered during drilling of the Lyons Formation with wireline logs confirming the penetrated Lyons Sandstone Formation to be high-quality and gas saturated.
Flow testing since TD has revealed increasing natural flow rates, reaching approximately 320 Mcfd to-date. Strong pressure build-up post-testing indicates high permeability and good reservoir communication. Based on previous engineering studies and observed flow rates, the projected stabilised flow rates constrained for production optimisation are expected to be between 350 Mcfd and 450 Mcfd, with a maximum of 550 Mcfd.
Initial laboratory analysis of gas samples from Jackson-27 showed a helium concentration up to
Galactica/Pegasus Development
The Galactica project forms part of the broader Galactica/Pegasus development, discovered by Blue Star in 2022. This large-scale project offers multiple potential product streams. Blue Star is advancing the Galactica project in joint venture with Helium One Global Ltd.
Blue Star previously released results of an independent engineering analysis of wells in the Galactica-Pegasus project and this analysis established maximum stabilised rates and drawdown for development planning and economic modelling.
The analysis integrated results from the State-16 well with test data from the JXSN-1, JXSN-2, JXSN-3, and JXSN-4 discovery wells and compared it to public information from the adjacent Red Rocks development.
The study concluded:
o Calculated permeabilities in the JXSN discovery wells and State-16 well range from 300 millidarcies ("mD") to 750 mD
o This permeability range suggests initial flow rates at 6 pounds per square inch absolute ("psia") wellhead pressure of 334 Mcfd to 780 Mcfd
o The State-16 well showed a calculated permeability of 405 mD in the Upper Lyons Sandstone Formation, and stabilised initial flow rates constrained for production optimisation would be 250 Mcfd to 350 Mcfd with a maximum of 441 Mcfd
Development planning includes considering vacuum compression ranging from 11 psia (-1 pounds per square inch gauge ("psig")) to 6 psia (-6 psig) wellhead pressure which provides the ranges above.
The Jackson-27 well has shown a natural flow rate of approximately 320 Mcfd which compares favourably to the State-16 well which showed a sustained natural flow rate of 150 Mcfd.
Given the higher natural flow at Jackson-27, due to greater permeability in the high-quality Upper Lyons Sandstone Formation, and the previous independent engineering study, projected potential stabilised flow rates, constrained for production optimisation, are expected to be 350 Mcfd to 450 Mcfd with a maximum potential rate of 550 Mcfd.

Notes to Editors
Helium One Global, the AIM-listed Tanzanian explorer, holds prospecting licences across two distinct project areas, with the potential to become a strategic player in resolving a supply-constrained helium market.
The Rukwa and Eyasi projects are located within rift basins on the margin of the Tanzanian Craton in the north and southwest of the country. These assets lie near surface seeps with helium concentrations ranging up to
The Company's flagship southern Rukwa Project is located within the southern Rukwa Rift Basin in south-west Tanzania. This project is considered to be entering an appraisal 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, successfully flowed
Following the success of the extended well test, the Company flowed significant quantities of helium to surface and 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.
