Southern Rukwa Helium Project Update

 

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 on the
Company's southern Rukwa Helium Project.

 

Highlights

·    Company has commenced operations in southern Rukwa ahead of further
testing using an Electrical Submersible Pump ("ESP")

·      ESP expected to arrive in Tanzania mid to late December ahead of
commencing ESP testing on ITW-1

·    Associated equipment and rig crews already on site and completion
string successfully retrieved from ITW-1 well using Company's drilling rig

·     Contract executed with wireline services provider; Digital Borehole
Surveying (PTY) Ltd ("DS") with logging activity currently ongoing

·      Logging of open hole Basement section will be completed ahead of
commencing ESP operations

·     Civils work completed at site for water disposal during ESP
operations, as well as road upgrades to access routes ahead of wet season

·   Company awarded "Certificate of Incentives" for Mineral Processing by
the Tanzania Investment and Special Economic Zones Authority ("TISEZA")

 

Lorna Blaisse, Chief Executive Officer, commented:

"This is the next step forward in progressing the southern Rukwa development
in Tanzania. We remain hopeful that by being able to increase the flow rate
from this discovery well using an ESP, we will see increases in the helium
concentration and gas-water ratio. Our understanding is that the helium is
sourced from the Basement and below, and we will be attempting to produce from
this area at increased rates using the ESP as artificial lift. This will
hopefully enable us to advance our contingent resource classification towards
bookable reserves and further progress this development to the production
stage.

The team continue to work hard in executing the deliverables of this important
phase, and I'd like to also extend our thanks to the support of the local
communities where we operate and to the Ministry of Minerals and the Mining
Commission."

 

 

 

Operational Preparation and Wireline Logging ahead of ESP Operations

The Company has commenced the next phase of its operations at ITW-1 in
southern Rukwa, ahead of the ESP testing. The Company-owned Predator 220
drilling rig has successfully re-entered the ITW-1 wellbore and recovered the
2⅞" completion string, together with the production packers.  The well has
also been prepared for follow-on wireline logging operations. This was
undertaken by pumping a completion brine into the hole which removed residual
cuttings in the well. DS are currently on site and will acquire in situ
wireline logs and evaluate the results ahead of commencing ESP activities.

The rig crew are onsite and will be working with the wireline logging crew to
deliver safe and effective data acquisition. The Company will evaluate these
logs to establish the fracture network within the open hole Basement section
ahead of ESP operations, in order to maximise flow rates across the targeted
interval.

 

ESP Equipment Mobilisation and Planned Testing

The operational preparation was necessary to de-risk the initial part of the
ESP operation and puts the Company in a position where it can install and run
the downhole and surface ESP equipment on the ITW-1 well ahead of testing. The
ESP equipment is currently being shipped from China and will be mobilised to
site once it has arrived in country and cleared customs.

In addition to helium, the Company recognises that a significant volume of
water will be produced during this testing phase. The civils work that will
allow for disposal of this water is now complete, and a comprehensive water
discharge plan is now in place. Water production is a metric that is used for
production curves (see Sproule ERCE CPR on ITW-1 - May 2025) due to the
relationship between the "gas in solution" play that is seen in the southern
Rukwa Basin, with the produced water a mixture of meteoric and shallower
formation fluid. The helium in this area is not dissolved within the water and
remains in the free gas state. Therefore, to determine helium, and other gas
flow rates, the water flow rate potential must be first considered. The helium
gas remains in its free gas state due to the associated reservoir pressure,
temperature and chemical inertness.

 

Certificate of Incentives Awarded

The Company is pleased to announce that it has recently been awarded a
"Certificate of Incentives" for Mineral Processing by TISEZA. This award has
been made in conjunction with the Tanzania Investment Centre, a government
authority aimed at facilitating investment and growth in Tanzania across key
sectors.

Having been awarded this certificate, the Company now has access to certain
fiscal incentives including relief from import duties.

The Company awaits engagement from the Government regarding the execution of
the regulatory agreements and the formal signing ceremony, following the
recent election. Further announcements will be made as appropriate.

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 and the
480km(2) 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 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 CO(2) 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 CO(2) 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.
