PULSAR HELIUM REPORTS COMMENCEMENT OF JETSTREAM #7 AND COMPLETION OF SEISMIC
SURVEY AT THE TOPAZ HELIUM PROJECT, USA

Pulsar Helium Inc. (AIM: PLSR, OTCQB: PSRHF, TSXV: PLSR) ("Pulsar" or the
"Company"), a primary helium company, is pleased to announce that drilling of
Jetstream #6 at the Company's flagship Topaz Project in Minnesota, USA has
been completed at a total depth (TD) of 2,597 feet. The drill rig has now
mobilized to Jetstream #7 where surface casing has been set and cemented and
drilling is underway. In addition, the extensive 2D active seismic acquisition
program at its Topaz Project has been completed, with a total of five seismic
lines spanning 41.5 miles having been successfully acquired.

Highlights:

•      Jetstream #6 Completed: Successfully drilled to a total depth
of 2,597 feet, encountering multiple pressurized gas intervals and further
supporting the Topaz geological model.

·          Previously reported gas zones at 1,287 ft (~576 psi),
2,120 ft (~981 psi), 2,187 ft (~1,012 psi) and 2,377 ft (~1,100 psi), with gas
observed at surface during drilling.

•            Jetstream #7 Underway: Drilling has commenced
following rig mobilization, targeting a planned TD of 3,000 feet, with
potential to deepen to 5,000 feet; located 2.2 miles northwest of Jetstream #1
as a significant step-out appraisal well.

•            2D Seismic Program Completed: Five seismic lines totaling
41.5 miles successfully acquired across the Topaz Project on February 20,
2026.

•         Independent QA/QC Reviewed: Raw seismic data reviewed onsite
by an independent expert contractor and validated as good quality.

Jetstream #6 Summary

Jetstream #6 has now been successfully drilled to a total depth of 2,597 feet
and is complete, marking another important milestone in the ongoing appraisal
of the Topaz Helium Project in Minnesota. During drilling, multiple
pressurized gas intervals were encountered, including zones previously
reported at 1,287 feet (~576 psi), 2,120 feet (~981 psi), 2,187 feet (~1,012
psi) and 2,377 feet (~1,100 psi), with gas observed bubbling to surface
through drilling fluids, confirming the presence of pressurized gas within the
intersected formations. The well was drilled using continuous HQ core to
maximize geological data recovery and further supports the Company's
geological model across the Topaz structure.

Jetstream #7

Drilling of the Jetstream #7 appraisal well commenced February 19, with a
planned TD of 3,000 feet and the potential to deepen to 5,000 feet. At the
time of writing this announcement, the surface casing has been set and
cemented and the hole is at a depth of 737 feet. Jetstream #7 is located 2.2
miles to the northwest of Jetstream #1, another considerable step out with the
intention of increasing the size of the Topaz resource.

Successful Completion of 2D Seismic Survey

Pulsar has successfully completed its extensive 2D active seismic acquisition
program at the Topaz Helium Project in Minnesota on February 20, 2026. The
survey, designed to comprise five lines totaling approximately 41.5 miles, was
undertaken to further elucidate the subsurface structure of the Topaz
reservoir and support ongoing resource assessment and future drilling target
definition. The program utilized low-impact seismic techniques, deploying
Vibroseis energy sources and wireless geophone nodes to generate
high-resolution cross-sectional images of the subsurface beneath each survey
line.

The raw seismic data has been QA/QC reviewed onsite by an independent expert
contractor and confirmed to be of good quality. The dataset is now being
transferred to Earth Signal in Calgary for processing and the interpretation
will be conducted in-house. The results are expected to enhance the Company's
structural understanding of the Topaz system, refine reservoir mapping, and
assist in optimizing future appraisal and development drilling.

About the Topaz Project

The Topaz Helium Project is a large-scale helium exploration opportunity
located in Minnesota, USA, a stable jurisdiction with established
infrastructure and access to experienced technical services. Exploration and
appraisal work to date has identified potentially saleable concentrations of
helium, helium-3 and carbon dioxide. Helium-3 is a rare isotope of helium with
strategic applications in national security, quantum computing and advanced
energy technologies, providing additional potential upside. A total of six
appraisal wells have been drilled at Topaz (the seventh is now underway), all
of which intersected pressurized gas, representing a 100% success rate to date
and supporting the geological model for the project. Ongoing technical work
continues to generate encouraging data and is focused on expanding the
Company's understanding of the resource through further appraisal, testing and
analysis. With a significant acreage position and multiple identified targets,
Topaz represents a core asset within the Company's portfolio and underpins its
strategy to build exposure to high-value industrial and specialty gas markets.

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
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 results of the 2D active seismic
acquisition successfully elucidating the subsurface structure, the potential
of CO2 and/or Helium-3 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 data 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 February 3, 2026, for the year
ended September 30, 2025, 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.
