Quantum Increases Working Interest in Sagebrush Helium Project to 90%

Operational Update

 

Quantum Helium Limited (AIM: QHE), advancing helium, hydrogen and hydrocarbon
projects in the USA, is pleased to announce that it has increased its working
interest in the Sagebrush Helium Project from 82.5% to 90% following the
acquisition of Jackal Oil Company's minority interest. The Company is also
pleased to report on progress across its helium portfolio in Colorado.

 
Highlights

·      Quantum increases its working interest in the Sagebrush Helium
Project from 82.5% to 90%

·      Sagebrush 3D seismic acquisition now in its final stages, with
initial processed results expected in January.

·      Sproule ERCE independent resource report for Coyote Wash expected
within a week, following completion of technical assessment.

·      Positive engagement with the BIA following cessation of
government shutdown, with flow testing of Sagebrush-1 expected to commence
early in the New Year upon receipt of final approvals.

Increase in Working Interest at Sagebrush

The Company has increased its working interest in the Sagebrush Helium Project
in Colorado from 82.5% to 90% through the acquisition of Jackal Oil Company's
minority interest. The remaining 10% working interest is owned by Quantum's
Chief Executive, Howard McLaughlin and is not carried.

The interest was acquired for a cash consideration of US$85,000. Jackal
elected to streamline its portfolio through a clean exit, and both parties
agreed terms that facilitated a straightforward restructuring of ownership.
The Board regards this as a highly favourable outcome for Quantum,
consolidating ownership in a project where the Company already holds a drilled
and cased helium discovery well that is being advanced towards production
testing.

This transaction further strengthens Quantum's strategic position at Sagebrush
as the Company enters a pivotal phase of operational activity.

There are no profits or losses attributable to the working interest being
acquired.

Sagebrush 3D Seismic Survey

The high-resolution 3D seismic acquisition programme at Sagebrush is now in
its final stages, with field operations expected to conclude within a week.
Once completed, the dataset will move into processing, with initial results
anticipated in January

The survey is designed to:

·      Refine the geometry and extent of the Leadville helium structure
intersected in Sagebrush-1

·      Improve imaging of additional algal mound targets across the
field

·      Support placement of future development and appraisal wells

·      Integrate seamlessly with existing 3D seismic coverage at Coyote
Wash

These results will directly inform the Company's 2026 drilling and development
planning.

Coyote Wash - Sproule Independent Resource Report

Sproule ERCE has now completed the majority of its technical work for the
independent resource evaluation of the Coyote Wash Helium Project, including
seismic reinterpretation, petrophysical review and volumetric assessment of
mapped structures.

The Company expects to receive the final report within the next week. The
evaluation is expected to provide an independent assessment of the resource
potential across Coyote Wash, where the Company has announced an internal best
estimate of 1,072 MMcf (million cubic feet) of 2U gross prospective helium
resource, and will play a central role in shaping Quantum's forward work
programme.

Regulatory Approvals - BIA Engagement and Timeline to Testing

Progress towards final approvals for the extended flow test at Sagebrush-1
continues. This week, Quantum held high-level meetings with senior Bureau of
Indian Affairs (BIA) officials, with very positive engagement and clear
forward progress.

While the Company had originally anticipated approvals earlier in the year,
timelines were impacted by the recent U.S. government shutdown, which delayed
federal administrative processes.

Upon receipt of the remaining approvals, Quantum intends to commence flow
testing at Sagebrush-1 early in the New Year, targeting confirmation of
deliverability from the known helium-bearing interval.

Quantum Helium Chairman, Carl Dumbrell, commented: "Consolidating our
ownership at Sagebrush at this stage of the project is a very positive and
strategic outcome for Quantum. We were able to agree terms that benefit both
parties while strengthening our position in what we regard as one of the
region's most compelling helium opportunities.

Operationally, momentum is building. The 3D seismic programme is nearly
complete, we expect to receive the Sproule report soon, and our meetings with
the BIA this week were constructive and encouraging. Once approvals are
finalised, we plan to initiate flow testing of Sagebrush-1 early in the New
Year.

Both Andrew Scott and I have recently added to our shareholdings, and we are
pleased to be invested alongside our fellow shareholders. We appreciate their
ongoing support as we move the business forward, with meaningful operational
milestones and a busy 2026 ahead."
