Independent CPR and Company Feasibility Study of the Southern Rukwa Helium Project in Tanzania

LONDON, GB / ACCESS Newswire / June 25, 2025 / 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 ("the Galactica Project"), provides an update following an independent competent person's report ("CPR") on the contingent and prospective resources at southern Rukwa Helium Project, Tanzania. The evaluation of helium resources and the subsequent completion of the CPR has been carried out and issued by leading international reserves auditors Sproule ERCE.

The evaluation of these helium resources in the southern Rukwa Helium Project are solely within the recently accepted 480km² Mining Licence ("ML") area (see fig.1). These resources are also broadly in line with those of the internal Company estimates which went into the Feasibility Study ("FS") and which formed the basis of the ML application for the southern Rukwa Helium Project in September 2024.

Highlights

• Deterministic sum of 2C Gross Helium Contingent Resources¹ for the Itumbula development have been evaluated by Sproule ERCE as 295,797 thousand standard cubic feet ("Mscf") and a 3C case of 1,345,591 Mscf Gross Helium Contingent Resources¹

• Additional Prospective Resources² within the remainder of the Mining Licence ("ML") area, excluding resources assigned to the Itumbula discovery, have been evaluated by Sproule ERCE as 709,239 Mscf (2U) and 3,227,556 Mscf (3U) (Unrisked)

• Contingent Resources¹ have been assessed by developing type curves and a well schedule for an Early Production System ("EPS"), followed by a further development with a Central Processing Facility ("CPF")

• Sproule ERCE have assigned Contingent Resources¹, sub-classified as 'Development on Hold' to the EPS for the first period of the ML. Further production beyond this point is assigned to the sub-class 'Development Unclarified', as a standard license extension will be required at the end of the initial 10-year term
