NEWS RELEASE | SEPTEMBER 19, 2025 | CASCAIS, PORTUGAL

PULSAR HELIUM CONFIRMS SUSTAINED HELIUM CONCENTRATIONS OF 7-8% AT JETSTREAM
#1, WITH POSITIVE RESERVOIR INDICATORS AT JETSTREAM #2

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the
"Company"), a leading helium project development company, is pleased to
announce the latest gas analysis results from the Jetstream #1 and Jetstream
#2 appraisal wells at its flagship Topaz helium project in Minnesota, USA.
Laboratory analysis confirms sustained helium concentrations of up to 8% in
both wells, reinforcing Topaz's status as a top-tier primary helium discovery.
The results reveal a highly favorable gas composition and exceptional well
performance with Jetstream #1 achieving a peak flow rate of over 1.3 million
cubic feet per day under well-head compression. These milestones underscore
the significant potential of the Topaz project and pave the way for
accelerated development initiatives.

Highlights

•           Jetstream #1 - Sustained helium concentrations
(7-8%): Laboratory testing has confirmed a stable, high helium content of
between 7-8% by volume in the Jetstream #1 gas stream, confirming a robust
helium-rich reservoir. This level comfortably exceeds typical commercial
thresholds (∼0.3% helium) and validates Jetstream #1's primary helium
production potential.

•           High CO₂ content (75-80%) - Byproduct potential:
Gas composition analyses show carbon dioxide levels of ~75-80% in the produced
gas. This unusually high CO₂ concentration (exceeding 70%) presents an
opportunity for commercial CO₂ byproduct utilization which has the potential
to enhance project economics.

•          Jetstream #2 - High helium and pressure, targeted cleanout
planned: The Jetstream #2 appraisal well encountered similarly high helium
concentrations of up to 8% in initial gas samples, alongside a strong initial
shut-in pressure ~151 psi (10.4 bar), notably higher than Jetstream #1. This
indicates a highly charged reservoir with excellent pressure support. However,
sustained flow from Jetstream #2 was limited due to persistent wellbore
blockages during testing. A targeted cleanout program is being planned.

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

"We are very encouraged by the consistency of helium grades across both
Jetstream wells, with favorable CO₂ levels expected to simplify processing
and enhance product yields. These latest datasets further validate the Topaz
Project's significant potential, with sustained helium concentrations of up to
8% at Jetstream #1 providing a robust foundation for future development.
Although sustained flow at Jetstream #2 has been restricted by persistent
wellbore blockages, a targeted cleanout program is being designed to address
these issues. With the upcoming core drilling, these programs position us to
unlock sustained production capability at Topaz and continue building momentum
toward establishing it as one of the leading new primary helium projects in
North America."

Latest Gas Analysis and Well Performance

Jetstream #1 - High helium, high deliverability: At the Jetstream #1 appraisal
well, which was deepened to 5,100 feet in 2025, laboratory gas analysis has
verified a sustained helium concentration of approximately 7-8% in the
produced gas over extended flow periods. This result far exceeds typical
economic requirements and reinforces the national significance of the
discovery. Jetstream #1 delivered a maximum natural flow rate of ~501 thousand
cubic feet per day (Mcf/d) during open flow testing, observed on a 38/64-inch
choke at approximately 30 psi (2.1 bar) well-head pressure, without
compression assistance. Jetstream #1 demonstrated stable long-duration flows,
producing 150-300 Mcf/d for periods of 12-18 hours on smaller choke sizes.
Under surface compression to reduce well-head pressure, the well delivered a
peak gas flow rate of ~1.3 MMcf/d (million cubic feet per day). No formation
water was encountered and the gas flowed dry, containing only helium, CO₂,
and trace gases. This clean flow confirms that Topaz's helium is not
associated with hydrocarbons or water, simplifying future production and
indicating that minimal gas separation processing will be required at the
wellhead.

The gas composition from Jetstream #1, chiefly CO₂ (~75-80%) and helium
(7-8%), is highly advantageous for commercial development. Methane content is
recorded at less than 3%, which means the gas is effectively free of the
hydrocarbons that otherwise complicate processing. Consequently, Pulsar can
focus on extracting helium and capturing the abundant CO₂ as a valuable
secondary product. The high helium concentration and low impurities underscore
that Topaz is a rare primary helium source, rather than a byproduct of
hydrocarbon gas, and bodes well for efficient helium purification and
liquefaction.

Jetstream #2 - Strong reservoir indicators and remediation: Laboratory
analysis of gas obtained from initial testing confirmed helium concentrations
on the order of 7-8%, closely mirroring the rich grades seen in Jetstream #1.
Initial shut-in pressure of approximately 151 psi, surpassed pressures
observed at Jetstream #1, a clear sign of a highly pressurized and energized
reservoir with capacity for strong gas flows. Together, the helium content and
pressure data from Jetstream #2 validate that the same extensive
helium-bearing system encountered in Jetstream #1 extends across the
reservoir, underpinning the project's scalability.

Testing at Jetstream #2 was, however, hindered by mechanical flow
restrictions. Despite the well's strong potential, persistent blockages in the
wellbore prevented the well from maintaining continuous flow during the
initial test period. In response, Pulsar is designing a targeted cleanout
operation to clear the obstruction and fully unleash Jetstream #2's capacity.
When the wellbore is cleaned out, further flow tests will be conducted to
gather sustained performance data from Jetstream #2. The Company is optimistic
that, after remediation, Jetstream #2 will demonstrate flow rates and
deliverability in line with its high helium grades and pressure, further
bolstering the Topaz project's already strong results.

All gas analyses were conducted by Isotech, a Stratum Reservoir brand, at
their laboratory in Champaign, Illinois, USA. Flow testing was undertaken by
Sabre Production Services LLC.

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 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 metres). In August 2025, the
Jetstream #1 appraisal well was successfully flow-tested using a wellhead
compressor, delivering a peak gas flow rate of approximately 1.3 million cubic
feet per day. Meanwhile, a multi-well drilling campaign at Topaz is set to
commence in early October to increase the Company's understanding of the
helium reservoir and advance Pulsar's strategy to become a leading helium
producer in response to growing global demand.

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.
