NEWS RELEASE | MARCH 18, 2026 | CASCAIS, PORTUGAL

PULSAR HELIUM REPORTS COMPLETION OF JETSTREAM #7 AND COMMENCEMENT OF DOWN-HOLE
LOGGING AT THE TOPAZ HELIUM PROJECT, USA

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the
"Company"), a primary helium company, is pleased to announce the successful
completion of drilling at the Jetstream #7 appraisal well at the Company's
flagship Topaz Helium Project in Minnesota, USA, having reached a total depth
(TD) of 2,979 feet (908 meters) on March 10, 2026. As previously reported
(news release March 4, 2026
(https://s203.q4cdn.com/212931576/files/doc_news/Pulsar-Helium-Reports-Pressurized-Gas-Encounter-at-Jetstream-7-at-the-Topaz-Helium-Project-USA-2026.pdf)
), gas was encountered during drilling at approximately 2,107 feet (642
meters) with a preliminary bottom-hole pressure of approximately 953 pounds
per square inch (psi), with visible gas influx confirming a strongly
pressurized system. Down-hole logging of Jetstream #7 was completed on March
17, 2026, with the logging truck now mobilizing to Jetstream #6. The drill rig
has mobilized to Jetstream #5 to facilitate the recovery of the drill string
that is in the hole, following which this campaign of exploratory drilling
will successfully conclude. Flow and pressure build-up testing of the
Jetstream wells is anticipated to commence in late March or early April 2026.
The Jetstream wells continue to maintain a 100% success rate of intersecting
pressurized gas.

Highlights:

•             Jetstream #7 drilling completed: Drilling of
Jetstream #7 reached a total depth of 2,979 feet (908 meters) on March 10,
2026, successfully concluding the well.

•             Previously reported gas encounter: As reported in
the Company's news release of March 4, 2026, gas was encountered at
approximately 2,107 feet (642 meters) with a preliminary bottom-hole pressure
of approximately 953 psi. Visible gas influx was observed during drilling
operations, confirming a strongly pressurized system.

•             100% success rate maintained: All seven Jetstream
appraisal wells drilled at Topaz to date have encountered pressurized gas,
underscoring the continuity and strength of the Topaz helium system.

•             Down-hole logging of Jetstream #7
complete: Down-hole logging was completed by Extreme Wireline on March 17,
2026, collecting a full suite of logs, including Compact Microimager (CMI).
The wireline logging truck has now mobilized to Jetstream #6, where logging
operations are expected to commence shortly.

•             Jetstream #5, final preparation for logging and
flow testing: The drill rig is mobilized to Jetstream #5 to complete standard
engineering operations to retrieve or bypass drill string remaining in the
well, after which the rig will demobilize and the well will be fully prepared
for logging and flow testing alongside the wider Jetstream program.

•             Flow and pressure build-up testing: Flow and
pressure build-up testing across the Jetstream wells is anticipated to
commence in late March or early April 2026. Timing reflects standard well
preparation and clean-out operations required prior to testing to ensure
acquisition of accurate and representative data.

•             Seismic data processing complete: Processing of
the 2D active seismic data acquired in February 2026 has been completed by
Earth Signal (Calgary). The dataset has been confirmed to be of good quality
and will now be interpreted by Chief Geologist Professor Nick Schofield, with
results expected to enhance the Company's structural understanding of the
Topaz system and inform future appraisal targeting.

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

"The successful completion of Jetstream #7 marks the end of an intensive and
highly productive exploratory drilling campaign at Topaz, one that has
delivered a perfect seven-from-seven success rate. Gas has been encountered in
every single well drilled, a remarkable outcome that continues to validate the
strength of our geological model. With down-hole logging now underway across
the field and flow testing set to commence imminently, we are on the cusp of
defining the scale and commercial potential of the Topaz resource. At a time
when the strategic importance of new primary helium supply from stable
jurisdictions has never been clearer, we look forward to updating the market
as results from the testing program are received and verified."

Summary of Jetstream #7

Drilling of the Jetstream #7 appraisal well reached a total depth of 2,979
feet (908 meters) on March 10, 2026. As reported in the Company's news release
of March 4, 2026
(https://s203.q4cdn.com/212931576/files/doc_news/Pulsar-Helium-Reports-Pressurized-Gas-Encounter-at-Jetstream-7-at-the-Topaz-Helium-Project-USA-2026.pdf)
, the well intersected a pressurized gas zone at approximately 2,107 feet (642
meters), with a preliminary bottom-hole pressure of approximately 953 psi and
visible gas influx observed at surface, confirming a strongly pressurized
system.

Down-Hole Logging

Down-hole logging of Jetstream #7 was completed on March 17, 2026, by Extreme
Wireline INC. The down-hole logging suite employed a full set of logging
tools, including Compact Microimager (CMI), providing detailed petrophysical
and geological data across the full drilled interval to characterize the
gas-bearing formations encountered during drilling. The wireline logging truck
has now mobilized to Jetstream #6, where logging operations are expected to
commence shortly.

Jetstream #5, Drill String Recovery

The drill rig is mobilized to Jetstream #5, where, as previously reported
(news release January 28, 2026), 1,239 feet of drill string remains in the
well following operations at TD. The rig will undertake operations to retrieve
or bypass the drill string, enabling the logging of the 3,839-foot
(1,170-meter) well. Upon successful completion of this work, the drill rig
will leave site, and this campaign of exploratory drilling at the Topaz Helium
Project will successfully conclude.

Flow Testing and Pressure Build-Up Program

Pulsar anticipates commencing a coordinated flow and pressure build-up testing
program across the Jetstream wells in late March or early April 2026. Timing
reflects standard well preparation and clean-out operations required prior to
testing to ensure acquisition of accurate and representative data. The program
is expected to consist of an initial flow testing phase followed by a period
of pressure build-up. Interim results will be released to the market as data
is received and verified by the Company.

Seismic Data Processing

Processing of the 2D active seismic data acquired across the Topaz Project in
February 2026 has been completed by Earth Signal in Calgary. The processed
dataset has been confirmed to be of good quality. Interpretation of the
seismic data will now be undertaken by Chief Geologist Professor Nick
Schofield. 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 activities.

About the Topaz Project

The Topaz Helium Project is a 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 seven
appraisal wells have been drilled at Topaz, all of which intersected
pressurized gas, representing a 100% success rate to date and supporting the
geological model for the project. With seven appraisal wells drilled and a
100% success rate, the Topaz Project now moves into a pivotal flow testing
phase that is expected to define the scale and commercial potential of the
helium resource, underpinning the Company's strategy to become a leading
supplier of primary helium 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 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 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 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 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.
