Successful extended well test in faulted Karoo interval at ITW-1 flows up to
7.6% helium

Helium One Global (AIM: HE1), the primary helium explorer in Tanzania, is
pleased to announce that it has completed the first phase of the extended well
test ("EWT") at Itumbula West-1 ("ITW-1") and has successfully flowed up to
7.6% helium to surface.

Highlights

·    Successful completion of the EWT on the faulted Karoo Group interval
flows up to 7.6% helium

·    The well flowed an average of 786 barrels per day ("bpd") of fluid on
a 22/64ths of an inch choke setting

·   The well naturally flowed for a period of five days with helium gas in
solution, and little to no air contamination in what has been determined to be
a pure helium/nitrogen mix

·  Onsite pressure-volume-temperature ("PVT") laboratory and portable Mass
Spectrometer measured helium concentrations

·    The Company is now in the process of undertaking the second EWT in
the fractured Basement

 

Details

After running and cementing the slotted casing, the Company commenced the
planned EWT operation across the first of two intervals in the ITW-1 well. As
reported in February 2024, this well previously flowed 4.7% helium to surface
from Basement during a Drill Stem Test.

Through the EWT, the Company has now successfully flowed the well across the
faulted Karoo Group interval for a period of five days, and the maximum helium
gas measured from solution yielded a compositional mix of 7.6% helium
(uncorrected for air contamination), 1.7% argon, 0.7% oxygen and 90% nitrogen.
These results were evaluated using an onsite Mass Spectrometer and verified
from downhole samples by a field PVT laboratory at the well site. The 7.6%
helium was air corrected to 7.9% helium, giving confidence in the onsite
measurement process.  A measured helium concentration of 7.6% equates to over
fourteen thousand times above background levels (5.3parts per million).

Over the five-day test period, the well flowed an average of 5% helium
(uncorrected). It was also observed that the concentration of hydrogen
decreased as helium increased, yielding a maximum measured hydrogen
concentration of 1.2%.

The well was initially choked to 20/64ths and flowed for ~22.5 hours with an
average flow rate of ~688 bpd of fluid. The well was then choked back to
22/64ths and then flowed for ~16 hrs with an average flowing rate of ~786 bpd
of fluid.

The data is currently being evaluated by the Company's subsurface team and a
maximum flow rate will be determined following the completion of the Basement
EWT.

The Company has now moved to the Basement to continue the EWT at that
interval, including opening up the well fully to obtain a maximum flow rate.
The Company looks forward to providing further updates in due course.

 

Lorna Blaisse, Chief Executive Officer, commented:

"We are very pleased with these results from the EWT in the faulted Karoo
interval. This is a globally unique helium play and it has taken a lot of hard
work and collective effort across multiple disciplines to establish how this
system works in the southern Rukwa Basin.

We have gained a huge amount of information from this Karoo EWT and look
forward to seeing what the fractured Basement EWT is going to yield. Once we
have completed testing on this second interval, we plan to finalise our
integrated subsurface modelling and resource estimates to complete our
feasibility study."

Notes to Editors

Helium One Global, the AIM-listed Tanzanian explorer, holds prospecting
licences across three distinct project areas, with the potential to become a
strategic player in resolving a supply-constrained helium market.

The Rukwa, Balangida, and Eyasi projects are located within rift basins on the
margin of the Tanzanian Craton in the north and southwest of the country. The
assets lie near surface seeps with helium concentrations ranging up to 10.6%
helium by volume. All Helium One's licences are held on a 100% equity basis.

The Company's flagship southern Rukwa Project is located within the Rukwa Rift
Basin covering 1,900km(2) in south-west Tanzania.  This project is considered
to be entering an appraisal stage following the success of the 2023/24
drilling campaign, which has proved an established helium system where the
Itumbula West-1 exploration well successfully flowed 4.7% helium to surface in
Q1 2024. Additional follow-on leads and prospects are defined by subsurface
database including multispectral satellite spectroscopy, airborne gravity
gradiometry, 2D seismic data, and QEMSCAN analysis.

Helium One is listed on the AIM market of the London Stock Exchange with the
ticker of HE1 and on the OTCQB in the United States with the ticker HLOGF.
