PULSAR HELIUM ANNOUNCES PROMISING PRE-FEASIBILITY RESULTS FOR TUNU PROJECT IN
EAST GREENLAND

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the
"Company"), a leading helium project development company, is pleased to report
that an independent Pre-Feasibility Study ("PFS") by Sproule-ERCE has
confirmed the promising geothermal reservoir potential and associated helium
production opportunity at the Company's Tunu helium-geothermal project in East
Greenland ("Tunu" or the "Project").

Although the data in the area is too limited to confirm the feasibility at
this stage, the assessment identifies a geothermal resource near the town of
Ittoqqortoormiit, with estimated reservoir temperatures between 80-130°C,
where conductive faults/fractures are considered the main driver behind fluid
flow. It highlights dual development scenarios that could supply renewable
power to the local community and enable commercial helium extraction from
produced gases, underscoring Tunu's promise as a dual clean energy and
industrial gas project.

Highlights

•          Independent PFS by Sproule-ERCE confirms the presence of an
active geothermal system beneath Liverpool Land, with geochemical and
geophysical evidence indicating subsurface reservoir temperatures of
80-130°C.

•         Reservoir analytical modelling shows potential flow rates of
up to ~720 m³ / hour in the best-case scenarios, supporting the production of
geothermal power sufficient to supply the entire settlement of
Ittoqqortoormiit with clean energy, while also providing surplus capacity for
helium separation.

•             In high-case scenarios, helium recovery could reach ~350
thousand cubic feet (Mcf) per day, representing one of the most prospective
primary helium opportunities in Europe, unassociated with hydrocarbons.

•             Binary cycle and dual-flash geothermal power
systems were identified as the most feasible options, with estimated capital
expenditures of USD $20-30 million, demonstrating realistic pathways to
integrated helium and renewable power production.

•        The Governments of Greenland and Denmark have announced funding
for a new airport at Ittoqqortoormiit, adjacent to the Tunu Project with
construction slated to commence in 2026. The airport will provide year-round
access and dramatically improve logistics for Pulsar's future field programs
and potential development.

Thomas Abraham-James, President & CEO of Pulsar, commented:

"The results of this independent Pre-Feasibility study, combined with the
announcement of a new airport at Ittoqqortoormiit, highlight the extraordinary
potential of the Tunu Project. Tunu is not only one of the very few primary
helium prospects in Europe, but also a project that aligns perfectly with
Greenland and Europe's future energy and critical raw material needs."

"With minimal existing infrastructure in East Greenland, the ability to power
our planned helium plant directly from geothermal energy is transformative,
delivering clean, baseload electricity to the local community while
simultaneously reducing our operational expenses as we develop a pathway
towards sustainable helium production. This unique synergy of renewable power
and critical resource development positions Pulsar to both support the
Greenlandic community with reliable energy and deliver helium to global
markets at a time of growing strategic demand. We are excited to advance into
the next phase of exploration and unlock the significant opportunities at
Tunu."

Pre-Feasibility Study Detail

The independent Pre-Feasibility Study by Sproule-ERCE provides preliminary
evidence that Tunu could host a working geothermal system capable of producing
both clean energy and helium. Analysis of hot spring samples indicates
underground temperatures of 80-130°C, warm enough to generate electricity. In
the best-case scenario, the fractured rocks beneath Tunu could allow enough
hot water to flow to the surface to power both the local community of
Ittoqqortoormiit and the equipment needed to separate helium from the gases
dissolved in the water.

If these stronger flow conditions are confirmed, a single well pair could
fully decarbonize Ittoqqortoormiit's electricity supply and provide an
additional 4.2 megawatts of power for helium processing. This would support
daily helium production of ~350,000 cubic feet, positioning Tunu one of the
very few primary helium resources in Europe. The study examined different
plant designs, finding that either a binary cycle or a double flash system
could achieve these results. Costs for such facilities are estimated at
US$20-30 million, a relatively modest investment considering the scale of the
opportunity and the low-carbon credentials of the project.

The study also makes clear that outcomes depend heavily on the size and
connectivity of the underground fracture system. If the rock proves less
permeable, flow rates, and therefore power and helium volumes, could be lower.
To reduce this risk, Sproule-ERCE recommends a focused 2026 program including
magneto-telluric surveys, further hot spring sampling, and eventually a slim
appraisal well to directly measure reservoir conditions. These steps will
allow Pulsar to refine the project design, strengthen confidence for investors
and potential partners, and unlock a strategically important source of
renewable power and critical helium supply for Europe.

Regional Infrastructure Update

The Governments of Greenland and Denmark have announced plans to fund a new
airport at Ittoqqortoormiit with construction slated to begin in 2026 until
2029. This facility, located adjacent to the Tunu Project, will provide direct
year-round access to a region that is currently only seasonally accessible by
ship and charter flights. The new airport is expected to substantially reduce
logistical costs and increase efficiency for Pulsar's future field programs
and eventual construction activities, further improving the economic outlook
for Tunu.

Project Progress to Date

Over the past 18 months, Pulsar has advanced Tunu from a conceptual
opportunity to a defined project supported by multiple independent lines of
evidence. Early surface exploration identified hot springs venting gases with
helium concentrations as high as 0.8%, one of the highest levels measured in
Europe. This discovery underscored Tunu as a rare primary helium occurrence
un-associated with hydrocarbons.

In 2024, Pulsar executed a passive seismic survey across the Kap Tobin
prospect, deploying 150 sensors at close spacing. The survey identified two
prominent low-velocity anomalies between 50-200 meters depth, coincident with
surface hot springs and a major fault system. These anomalies are interpreted
as fractured reservoirs capable of storing and channeling helium-rich fluids.
The data also indicated a higher degree of fracturing than previously
anticipated, a positive sign for both gas migration and geothermal
circulation.

To build on these results, Pulsar engaged Sproule-ERCE in June 2025 to conduct
the Pre-Feasibility Study. Leveraging its global geothermal expertise,
Sproule-ERCE integrated the seismic, geochemical, and geological datasets into
a coherent subsurface model and delivered the assessment now reported.

Mineral Exploration Licence

Pulsar is the first company licensed for helium exploration in Greenland,
holding an exclusive Mineral Exploration Licence 2025/101 and a non-exclusive
Prospecting Licence 2021/46. The Tunu project is wholly within MEL 2025/101
that was granted in 2025 and has an initial term of five years, extendable up
to 22 years, providing the Company with a long-term foundation for project
development.

About the Tunu Project

Pulsar's Tunu Project is located on the east coast of Greenland, near
Ittoqqortoormiit and the Scoresby Sound fjord system. The Project is notable
for being one of the few primary helium occurrences identified in Europe, with
helium concentrations in sampled hot springs reaching up to 0.8% and also
demonstrates significant geothermal energy prospectivity with reservoir
temperatures estimated between 80°C and 110°C, making cogeneration of power
and heat potentially feasible. The gas composition is primarily nitrogen and
helium, and is not associated with hydrocarbons or CO2, which is rare among
global helium projects.

Forward-Looking Statements

This news release contains forward-looking information within the meaning of
Canadian securities legislation (collectively, "forward-looking statements")
that relate to the Company's current expectations and views of future events.
Any statements that express, or involve discussions as to, expectations,
beliefs, plans, objectives, assumptions or future events or performance
(often, but not always, through the use of words or phrases such as "will
likely result", "are expected to", "expects", "will continue", "is
anticipated", "anticipates", "believes", "estimated", "intends", "plans",
"forecast", "projection", "strategy", "objective" and "outlook") are not
historical facts and may be forward-looking statements. Forward-looking
statements herein include, but are not limited to, statements relating to the
potential impact for conducting geophysical surveys, drilling future wells,
and a pre-feasibility study at the Tunu Project. Forward-looking statements
may involve estimates and are based upon assumptions made by management of the
Company, including, but not limited to, the Company's capital cost estimates,
management's expectations regarding the availability of capital to fund the
Company's future capital and operating requirements and the ability to obtain
all requisite regulatory approvals.

No reserves have been assigned in connection with the Company's property
interests to date, given their early stage of development. The future value of
the Company is therefore dependent on the success or otherwise of its
activities, which are principally directed toward the future exploration,
appraisal and development of its assets, and potential acquisition of property
interests in the future. No un-risked Contingent and Prospective Helium
Volumes have been defined at the Tunu Project. However, estimating helium
volumes is subject to significant uncertainties associated with technical data
and the interpretation of that data, future commodity prices, and development
and operating costs. There can be no guarantee that the Company will
successfully convert its helium volume to reserves and produce that estimated
volume. Estimates may alter significantly or become more uncertain when new
information becomes available due to for example, additional drilling or
production tests over the life of field. As estimates change, development and
production plans may also vary. Downward revision of helium volume estimates
may adversely affect the Company's operational or financial performance.

Helium volume estimates are expressions of judgement based on knowledge,
experience and industry practice. These estimates are imprecise and depend to
some extent on interpretations, which may ultimately prove to be inaccurate
and require adjustment or, even if valid when originally calculated, may alter
significantly when new information or techniques become available. As further
information becomes available through additional drilling and analysis the
estimates are likely to change. Any adjustments to volume could affect the
Company's exploration and development plans which may, in turn, affect the
Company's performance. The process of estimating helium resources is complex
and requires significant decisions and assumptions to be made in evaluating
the reliability of available geological, geophysical, engineering, and
economic date for each property. Different engineers may make different
estimates of resources, cash flows, or other variables based on the same
available data.

Forward-looking statements are subject to a number of risks and uncertainties,
many of which are beyond the Company's control, which could cause actual
results and events to differ materially from those that are disclosed in or
implied by such forward- looking statements. Such risks and uncertainties
include, but are not limited to, that Pulsar may be unsuccessful in drilling
commercially productive wells; the uncertainty of resource estimation;
operational risks in conducting exploration, including that drill costs may be
higher than estimates ; commodity prices; health, safety and environmental
factors; and other factors set forth above as well as risk factors included in
the Company's Annual Information Form dated July 31, 2025 for the year ended
September 30, 2024 found under Company's profile on www.sedarplus.ca
(http://www.sedarplus.ca) .

Forward-looking statements contained in this news release are as of the date
of this news release, and the Company undertakes no obligation to update or
revise any forward-looking statements, whether as a result of new information,
future events or otherwise, except as may be required by law. New factors
emerge from time to time, and it is not possible for the Company to predict
all of them or assess the impact of each such factor or the extent to which
any factor, or combination of factors, may cause results to differ materially
from those contained in any forward-looking statement. No assurance can be
given that the forward-looking statements herein will prove to be correct and,
accordingly, investors should not place undue reliance on forward-looking
statements. Any forward-looking statements contained in this news release are
expressly qualified in their entirety by this cautionary statement.
