PULSAR HELIUM INC. ANNOUNCES FILING OF PRELIMINARY SHORT FORM BASE SHELF

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the "Company"), a leading helium exploration and development company, is pleased to announce that it has filed a preliminary short form base shelf prospectus with the securities regulatory authorities in each of the provinces and territories of Canada.

The preliminary short form base shelf prospectus, when made final, will allow Pulsar to offer and issue, from time to time over a 25‑month period, common shares, debt securities, warrants, subscription receipts and units (collectively, the "Securities") up to an aggregate offering amount of US$50,000,000. The specific terms of any future offering of Securities, including the intended use of proceeds, will be established at the time of such offering and described in a shelf prospectus supplement to be filed with the applicable Canadian securities regulatory authorities. The Company currently has no contemplated plan to raise capital,  and there is no certainty that any Securities will be offered or sold under the base shelf prospectus during its term.

The base shelf prospectus may also qualify "at‑the‑market distributions" as defined in National Instrument 44‑102 - Shelf Distributions, permitting sales of Securities (including common shares) into the existing Canadian or other trading markets, if applicable, subject to the terms to be described in any applicable shelf prospectus supplement.

A copy of the preliminary short form base shelf prospectus is available under Pulsar's profile on SEDAR+ at www.sedarplus.ca.  

On behalf Pulsar Helium Inc.

"Thomas Abraham-James"

President, CEO and Director

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 potential offerings of Securities under the base shelf prospectus, the filing of a final base shelf prospectus, potential "at‑the‑market distributions" and the Company's financing flexibility and future use of proceeds. 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.

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.
