Helium One Global Ltd Announces Jackson-31 Flow Testing and Gas Sampling Analysis
Helium One Global has announced positive flow testing and gas sampling results from the Jackson-31 development well at its Galactica helium project in Colorado. The well, drilled to 1,210 feet, demonstrated strong natural gas flow rates reaching approximately 250 thousand cubic feet per day (Mcfd).
Initial laboratory analysis revealed helium concentrations up to 2.2% air corrected (1.9% not air corrected), with projected reservoir helium concentration expected to equilibrate to 2.3-2.5%. Based on engineering analysis, the well's projected stabilized flow rates are expected between 300-400 Mcfd, with a maximum potential of 500 Mcfd.
The well encountered high-quality, gas-saturated Lyons Sandstone Formation at 1,153 feet, with strong pressure build-up post-testing indicating high permeability and good reservoir communication. The gas composition shows approximately 69% CO2 and 29% nitrogen.

Jackson-31 Summary Analysis
The well reached a TD of 1,210 feet (368m) within the Upper Lyons Formation, encountering the Lyons Sandstone at 1,153 feet (351m). As expected, no water was encountered during drilling of the Lyons Sandstone with wireline logs confirming that the penetrated Lyons Sandstone Formation is of high-quality and gas saturated.
Flow testing since reaching TD has revealed increasing natural flow rates, reaching approximately 250 Mcfd of total gas. Strong pressure build-up post-testing indicates high permeability and good reservoir communication. Based on previous engineering analysis, and the observed flow rates, the projected stabilised flow rates constrained for production optimisation are expected to be between 300-400 Mcfd, with a maximum of 500 Mcfd projected.
Initial laboratory analysis of gas samples from Jackson-31 showed a helium concentration up to
Jackson-31 Initial Flow Test Results
The well reached a TD of 1,210 feet (368m), encountering the Lyons Formation at 1,153 feet (351m) and was deliberately completed 57 feet (17m) into the Upper Lyons Sandstone Formation.
The well exhibited natural gas flow during drilling and at TD. Flow testing has continued, with increasing results demonstrating natural flow rates of approximately 250 Mcfd total gas. Strong pressure build-up post-testing confirms high permeability and good reservoir communication. Well testing and sampling will continue throughout the current drilling campaign.
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 to public information from the adjacent Red Rocks development.
The study concluded:
Calculated permeabilities in the JXSN discovery wells and State-16 well range from 300 to 750 millidarcies ("mD")
This permeability range suggests initial flow rates at 6 psia wellhead pressure of 334 to 780 Mcfd
The State-16 well showed a calculated permeability of 405 mD in the Upper Lyons Formation
State-16 stabilised initial flow rates constrained for production optimisation would be 250 to 350 Mcfd with a maximum of 441 Mcfd
Development planning includes considering vacuum compression ranging from 11 psia (-1 psig) to 6 psia (-6 psig) wellhead pressure which provides the ranges above.
The Jackson-31 well has shown a natural flow rate of approximately 250 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-31, due to greater permeability in the high-quality Lyons Sandstone Formation and based on previous independent engineering, projected potential stabilised flow rates are expected to be 300-400 Mcfd with a maximum potential rate of 500 Mcfd.
Jackson-31 Well Gas Sampling Results
Gas samples from the Jackson-31 well have been collected and sent for laboratory analysis to determine helium and carbon dioxide concentrations.
Early gas samples from the Jackson-31 well showed a helium concentration up to
Further laboratory analysis will be conducted to perform air correction on samples taken during ongoing flow testing.

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 covering 1,664km2 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 has now flowed significant quantities of helium to surface and has filed a Mining Licence ("ML") application with the Mining Commission ("MC") of the Tanzanian Government and the MC have now offered the Company an ML consistent with the ML application.
