NEWS RELEASE | OCTOBER 23, 2025 | CASCAIS, PORTUGAL

PULSAR HELIUM APPOINTS DR. PETER BARRY AS SCIENTIFIC HELIUM-3 ADVISOR

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the
"Company"), a leading helium exploration and development company, is pleased
to announce the appointment of Dr. Peter Barry of the Woods Hole Oceanographic
Institution (WHOI) as the Company's Scientific Helium-3 Advisor. Dr. Barry, a
noble gas isotope geochemist and Associate Scientist at WHOI, and specialist
in crust-mantle interactions, will lead Pulsar's helium-3 research efforts as
the Company advances its flagship Topaz helium project in Minnesota. In this
role, Dr. Barry will spearhead Pulsar's helium-3 program, guide scientific
strategy while ensuring rigorous data analysis of all geochemical datasets.

In his advisory role, Dr. Barry will:

•          Interpret Noble Gas Data: Oversee the interpretation of
noble gas isotopic data from Pulsar's helium wells, providing expert insights
into helium-3 content and origin.

•        Research Grant Development: Drive the development of proposals
for research grants and partnerships, leveraging Pulsar's discoveries to
attract funding and collaborative opportunities in helium-3 research.

•        Collaborate with engineering team: Provide guidance on
solutions for the viable retrieval, containment, and preservation of helium-3,
supporting Pulsar's objective of product entry into the U.S. market.

Dr. Barry will also coordinate the independent validation of helium-3 in
Pulsar's gas samples. He will oversee the collection of gas samples from the
Topaz Project's Jetstream #1 well, and potentially other wells, and coordinate
with U.S. government laboratories to verify geochemical results. These
institutions will conduct high-precision analyses to confirm the presence and
isotopic composition of helium-3 in the samples, providing third-party
verification of Pulsar's results. This initiative underscores Pulsar's
commitment to the highest scientific standards as it evaluates the helium-3
potential of its discoveries and defines a pathway for helium-3 to become a
viable, saleable commodity within the Topaz reservoir's proven suite of
high-value gases.

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

"We are thrilled to welcome Dr. Peter Barry as our Scientific Helium-3
Advisor. Dr. Barry's expertise in noble gas geochemistry and his deep
understanding of helium systems will be invaluable as we advance the Topaz
Project and our broader helium-3 initiatives. His leadership will ensure that
our helium-3 analyses and reservoir models are conducted with rigorous
scientific oversight, strengthening Pulsar's position at the forefront of
terrestrial helium-3 exploration. This appointment underscores our commitment
to unlocking the full potential of the Topaz discovery and maintaining
Pulsar's lead in a field of growing strategic importance."

Strategic Importance of Helium-3

Helium-3 is one of the rarest and most valuable isotopes on Earth, with
reported prices reaching up to US$18.7 million per kilogram, over 100,000
times the price of common helium (helium-4). Its scarcity and unique
properties give it outsized strategic importance for both energy and
scientific innovation. Recognizing its value, NASA and the U.S. government are
actively funding efforts to extract helium-3 from lunar regolith. (The Moon's
soil is estimated to contain on the order of 1.4-15 parts per billion of
helium-3.) Against this backdrop, Pulsar's terrestrial helium-3 discovery at
Topaz, with measured concentrations up to 14.5 parts per billion (ppb) in the
Jetstream #1 well, is an extraordinary development. The levels identified at
Topaz are comparable to those found in lunar samples, highlighting the
world-class significance of Pulsar's find.

Dr. Peter Barry's Geochemistry Expertise

Dr. Peter Barry brings world-class scientific credentials to Pulsar's team. He
is an Associate Scientist in the Marine Chemistry & Geochemistry
department at WHOI, where he specializes in using noble gas and stable isotope
geochemistry to study Earth's volatile elements and geological processes. A
researcher at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts
- accredited by the New England Commission of Higher Education - Dr Barry's
work spans high-temperature geochemistry, crust-mantle interactions, and the
behavior of gases and fluids in the Earth's lithosphere. Notably, Dr. Barry
has extensively investigated the occurrence of helium in nature - recognized
for his work helping explain the distribution of major helium gas reservoirs
on Earth. He earned his Ph.D. in Earth Sciences from the Scripps Institution
of Oceanography (UC San Diego) and has held research positions at the
University of Tennessee and the University of Oxford.

Dr. Barry is no stranger to Pulsar's projects. As a noble gas isotope expert,
he has been consulting with the Company on the Topaz helium discovery since
its early stages. He analyzed the full suite of gas samples from the Jetstream
#1 well, which revealed helium concentrations up to 14.5% (by volume) in the
raw gas, and provided key interpretations that a small amount of air
contamination had likely made that helium reading a conservative estimate. His
guidance has been instrumental in characterizing the Topaz find, and in his
formal capacity as Scientific Helium-3 Advisor, he will expand this work to
drive Pulsar's helium-3 research forward.

About the Topaz Project

The Topaz project is located in northern Minnesota, USA, where Pulsar is the
first mover and holds exclusive leases. Drilling at the Jetstream #1 appraisal
well reached a total depth ("TD") of 5,100 feet (1,555 meters) in January
2025, successfully penetrating the entire interpreted helium-bearing reservoir
and beyond. Drilling of the Jetstream #2 appraisal well was completed on
February 1, 2025, reaching a TD of 5,638 feet (1,718 meters). In August 2025,
the Jetstream #1 well was successfully flow-tested using a wellhead
compressor, delivering a peak gas flow rate of approximately 1.3 million cubic
feet per day with a sustained flow of 7-8% helium (as helium-4). Recent
laboratory analyses have also confirmed the presence of helium-3 in measurable
concentrations, representing one of the highest naturally occurring helium-3
values publicly reported in a terrestrial gas reservoir. The forthcoming
multi-well drilling campaign will build on these results to expand Pulsar's
understanding of the reservoir and advance Topaz toward development.

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
statements regarding bringing the Topaz project to production, anticipated
full plant construction contract in 2026, final investment decision being made
in 2026, the potential impact of the drill results, flow testing and pressure
testing on the next iteration of the resource estimate; the potential of CO2
as a valuable by-product of the Company's future helium production; and the
potential for future wells. 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. Un-risked Contingent and Prospective Helium Volumes
have been defined at the Topaz 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.
