PULSAR HELIUM ANNOUNCES MAJOR FLOW TEST RESULTS AT JETSTREAM #1, TOPAZ PROJECT

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the
"Company"), a leading helium project development company, is delighted to
report major natural flow test results at the Jetstream #1 appraisal well,
part of the Topaz helium project in Minnesota, USA. These latest results mark
a major leap in well performance, with natural flow rates more than tripling
those recorded in 2024.

A summary of the results is as follows:

•             On August 15, 2025 Jetstream #1 achieved a peak
natural flow rate of ~501 thousand cubic feet per day (~501 Mcf/d) on a 38/64"
choke at ~30 pounds per square inch (psi) well head pressure (WHP), achieved
with no compression or stimulation. No formation water has been encountered;
the gas has flowed as dry gas.

•             Substantial improvement over 2024 tests: In April
2024, Jetstream #1 achieved a peak natural flow of ~150 Mcf/d at 34 psi WHP
(~821 Mcf/d under well-head compression) with helium concentrations ranging
from 8.7% to 14.5%; the well is now flowing at more than three times the rate
recorded in April 2024 under similar pressure conditions.

•             Significance and Next Steps: As Pulsar President
& CEO Thomas Abraham-James stated in April 2024, the Jetstream #1 results
confirmed a "major new helium discovery, putting Topaz in the top tier of
global primary helium projects". The latest test program builds decisively on
that foundation, validating Topaz's potential as a globally significant source
of primary helium.

•             Further updates imminent: Additional
sustained-flow results, flow results under well-head compression, and full gas
composition analyses are in the process of being obtained. When testing is
complete, all equipment will then be moved to Jetstream #2 for equivalent
testing.

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

"The deepening of the Jetstream #1 appraisal well to a total depth of 5,100
feet, penetrating the entire interpreted helium-bearing zone, has proven
highly successful. The well is now naturally flowing at ~501 thousand cubic
feet per day at 30 pounds per square inch WHP, more than three times the peak
natural flow achieved in 2024. This result validates our subsurface model,
significantly de-risks the Topaz project, and confirms the reservoir's
outstanding productivity. This is especially exciting considering the 2024 gas
analysis for the same well returned helium concentrations ranging from 8.7% to
14.5%. With further flow testing, including under well-head compression, and
gas composition analyses to follow, we look forward to sharing further
updates, and the results of Jetstream #2. These results underscore the immense
opportunity at Topaz and signal the start of unlocking its full potential."

Test Results and Analysis

The Jetstream #1 well delivered a maximum natural flow rate of ~501 thousand
cubic feet per day (Mcf/d) during open-flow testing on August 15, 2025. This
was observed on a 38/64-inch choke at approximately 30 psi WHP, without
compression assistance. By comparison, during initial appraisal in April 2024,
Jetstream #1 reached a peak natural flow of ~150 Mcf/d at 34 psi. The
improvement of more than threefold under near-identical pressure conditions
highlights the effectiveness of recent wellbore clean-up and deepening and
underscores the formation's strong productivity. Importantly, no formation
water has been encountered, the gas has flowed as dry gas.

In addition to the peak result, Jetstream #1 demonstrated stable long-duration
flows, producing 150-300 Mcf/d for periods of 12-18 hours on smaller choke
sizes. These sustained flows showed no significant decline and were followed
by rapid pressure recovery, indicating excellent reservoir recharge capacity.

Compression Testing and Expected Upside

To further assess the well's maximum capacity, Pulsar is commencing a
compression-assisted flow test. By reducing WHP via surface compression, flow
rates are expected to increase significantly. For reference, compression
applied during the February 2024 test program resulted in a maximum flow rate
of ~821 Mcf/d. The current test is designed to validate Jetstream #1's full
potential and provide key data for production facility design and future
development planning.

A Brief Explanation of Flow Testing Under 'Natural' Conditions and Under
'Compression'

When a well produces under natural flow, the gas comes to surface on its own,
pushed out purely by the pressure in the reservoir. It's a strong indicator of
how much energy the reservoir holds. With compression, special surface
equipment is used to lower the pressure at the wellhead, which makes it easier
for the gas to flow out. This doesn't change the size of the reservoir, but it
allows much higher flow rates and gives a clearer picture of the well's
maximum production potential.

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 metres) on January 11,
2025, successfully penetrating the entire interpreted helium-bearing reservoir
and beyond. The Jetstream #1 appraisal well previously reached TD of 2,200
feet (671 metres) on February 27, 2024, identifying top-tier helium
concentrations of up to 14.5%, well above the 0.3% widely accepted economic
threshold, and flowed at a rate of 821,000 cubic feet per day under well-head
compression. Drilling of the Jetstream #2 appraisal well was completed on
February 1, 2025, reaching a TD of 5,638 feet (1,718 metres). These activities
will progress Pulsar's strategy become a producer of helium, addressing
increasing 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
completion of the flow testing and pressure build up tests of  Jetstream #2,
the timing of completion of the flow testing and pressure testing; 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 completing
the flow testing and pressure testing of Jetstream #2, in drilling
commercially productive wells; the uncertainty of resource estimation;
operational risks in conducting exploration, including that flow-testing,
pressure testing and drill costs may be higher than estimates ; commodity
prices; health, safety and environmental factors; and other factors set forth
above as well as under "Cautionary Note Regarding Forward Looking Statements
and Market and Industry Data" and "Risk Factors" in the AIM Admission Document
published on October 14, 2024 found on the Company's web site at

Company's profile at 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
