CASCAIS, Portugal, Dec. 03, 2025 (GLOBE NEWSWIRE) -- Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) (“Pulsar” or the “Company”), a primary helium development company, is pleased to announce that the drill rig and all ancillary equipment have been relocated to the Jetstream #5 drill pad, located 1.8 miles (3 kilometers) northeast of Jetstream #1, at the Company’s flagship Topaz project in Minnesota, USA. Jetstream #5 has a planned target depth of 5,000 feet (1,524 meters). The Company is pleased to confirm that rigging-up operations commenced on Thursday, November 27, 2025, and that the Jetstream #5 well was spudded on Friday, November 28, 2025.

Topaz drilling campaign highlights:

Jetstream #1 (47.63468333 N / -91.70114444 W).

Helium-3 discovery: Concentrations of up to 14.5 parts per billion (ppb) were recorded in produced gas.

TD reached and helium zone penetrated: The Company's latest appraisal well, was successfully drilled to a total depth of 3,000 feet (915 meters) on November 25, 2025, penetrating the entire interpreted helium-bearing interval. During drilling, pressurized gas with an estimated bottom-hole pressure of approximately 887 psi was encountered at a depth of 1,897 feet (578 meters).

Completion: November 26, 2025
TD: 3,000 feet / 915 meters
Sustained Gas Concentrations: Unknown. Awaiting testing.
Natural Flow: Yes, value to be determined.
Well pressure: Bottom-hole pressure ~887 psi
Formation Water: None present

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 a TD of 5,100 feet (1,555 meters) in January 2025, successfully penetrating the entire interpreted helium-bearing reservoir and beyond. Drilling of the Jetstream #2 appraisal well was completed on February 1, 2025, reaching a TD of 5,638 feet (1,718 meters). Jetstream #3 reached TD on November 7, 2025, and during drilling the calculated bottom-hole pressure was ~960 psi, with down-hole testing and gas sampling to soon occur now that Jetstream #4 has been completed. In August 2025, the Jetstream #1 well was successfully flow-tested using a wellhead compressor, delivering a peak gas flow rate of approximately 1.3 million cubic feet per day with a sustained flow average of 8.1% helium (as helium-4). Recent laboratory analyses have also confirmed the presence of helium-3 in measurable concentrations The ongoing multi-well drilling campaign will build on these results to expand Pulsar’s understanding of the reservoir.

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 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 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.
