PULSAR HELIUM REPORTS PRESSURIZED GAS ENCOUNTER AT JETSTREAM #7 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 that the Jetstream #7 appraisal well at the Company's flagship Topaz Project in Minnesota, USA has intersected a pressurized gas zone. The gas zone was encountered at a depth of approximately 2,107 feet (642 meters) with a preliminary bottom-hole pressure of approximately 953 pounds per square inch (psi). Visible gas influx was observed during drilling operations, confirming a strongly pressurized system. The Jetstream wells continue to maintain a 100% success rate of intersecting pressurized gas.

Highlights:

•             Jetstream #7 gas encounter: Gas was encountered at approximately 2,107 feet (642 meters) with a preliminary bottom-hole pressure of approximately 953 psi, indicating a robustly pressurized reservoir system at greater depth relative to previous wells.

•             Higher pressure at depth: The significantly higher bottom-hole pressure encountered at Jetstream #7 further supports the presence of an active and laterally extensive gas-bearing system within the Topaz structure.

•             Drilling progress: Drilling is ongoing using continuous HQ core drilling (3.8 inch (96.0 millimeter) hole diameter) to maximize geological sample recovery while maintaining efficient progress. The planned total depth for Jetstream #7 is approximately 3,000 feet (914 meters), with the well design allowing for potential deepening in the future to approximately 5,000 feet (1,524 meters) depending on geological conditions and results.

•             Program momentum: All Jetstream appraisal wells drilled to date have encountered pressurized gas, underscoring the emerging continuity and strength of the Topaz helium system.

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

"Intersecting pressurized gas at over 2,100 feet with a bottom-hole pressure approaching 1,000 psi is an exceptional technical result and continues to validate our geological model at Topaz. Jetstream #7 demonstrates that the system remains strongly pressurized at increasing depths, which is highly encouraging as we advance the appraisal program.

With a planned total depth of 3,000 feet and the flexibility to deepen to 5,000 feet, we are well positioned to further evaluate the vertical extent and reservoir characteristics of this helium-bearing system."

Summary of Jetstream #7

Jetstream #7 is the seventh appraisal well drilled at the Topaz Helium Project in Minnesota, USA. During drilling operations, 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.

Drilling operations are continuing toward a planned total depth of 3,000 feet (914 meters). The well may be deepened in the future to approximately 5,000 feet (1,524 meters), subject to geological conditions and ongoing technical evaluation.

Data collected from Jetstream #7, including pressure information, core samples and gas observations, will contribute to the Company's expanding technical dataset and inform future resource evaluation and development planning at Topaz.

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 (the seventh still in progress), 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 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.  

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.
