PULSAR HELIUM REPORTS ADDITIONAL HIGH-PRESSURE GAS ENCOUNTER AT JETSTREAM #5 AND OUTLINES UPCOMING TESTING PROGRAM

Pulsar Helium Inc.'s Jetstream No. 5 appraisal well at the flagship Topaz project (Minnesota, United States) has encountered an additional pressurized gas influx at approximately 2,857 feet (871 metres) depth. The bottom-hole pressure of this new gas zone is estimated at ~1,292 psi, the highest recorded to date at Topaz. This follows previously reported pressurized gas zones intersected at approximately 837 feet (255 metres) and 1,481 feet (451 metres). Drilling of Jetstream #5 is ongoing and will continue toward a planned total depth of up to 5,000 feet (1,524 metres).

Upon completion of Jetstream No. 5, the drilling rig will mobilize to the next appraisal well, Jetstream No. 6, located roughly 2.2 kilometres southwest of the discovery well (Jetstream No. 1). In addition, preparations are under way for a multiwell flow testing program slated to commence in early February, 2026. This program will consist of flow testing followed by pressure buildups to evaluate the Jetstream No. 3, No. 4 and No. 5 wells. A six-week test period per well is expected. Pulsar will announce interim results from the Topaz testing campaign as data are received and verified by the company.

Highlights:

• Additional high-pressure gas: Jetstream No. 5 encountered additional high-pressure gas at approximately 2,857 feet depth, with a bottom-hole pressure of approximately 1,292 pounds per square inch (the highest observed at Topaz so far).
• Multiple gas zones: Prior pressurized gas was encountered at approximately 837 feet and approximately 1,481 feet in Jetstream No. 5.
• Continuing to total depth: Drilling is continuing at Jetstream No. 5, targeting a total depth of no more than 5,000 feet.
• Next well mobilization: Upon finishing Jetstream No. 5, the rig will move to drill Jetstream No. 6, located approximately 2.2 kilometres southwest of the Topaz discovery well (Jetstream No. 1).
• Coming testing program: A combined flow testing and pressure buildup program is anticipated to begin in early February, 2026, over approximately six weeks per well. The campaign will cover Jetstream wells No. 3, No. 4 and No. 5, with interim results to be shared with the market once data are collected and verified.

Jetstream No. 5 Update

Jetstream No. 5 was spudded on Nov. 28, 2025, as part of Pulsar's continuing multiwell appraisal program at the Topaz project. During drilling, pressurized gas was initially encountered at approximately 837 feet and 1,481 feet, with an early calculated bottom-hole pressure of approximately 662 pounds per square inch (at 1,481 feet depth), confirming a strongly pressurized gas system at relatively shallow depth.

As drilling progressed, a further gas influx was intersected at 2,857 feet, where the calculated bottom-hole pressure increased to approximately 1,292 pounds per square inch. Gas influx has been observed during drilling operations, particularly during pauses in circulation, indicating sustained gas presence within the formation.

Jetstream No. 5 is being drilled on a continuous basis, with the crew returning to work on Jan. 3 after commencing leave on Dec. 14, 2025. Drilling operations remain continuing, with the well advancing toward its anticipated total depth of no more than 5,000 feet. Upon finishing Jetstream No. 5, the rig will move to drill Jetstream No. 6, located approximately 2.2 km southwest of Jetstream No. 1.

Coming testing program

Pulsar is preparing for a co-ordinated testing program anticipated to commence in early February, 2026. The program is expected to utilize flow testing and pressure buildup equipment and is planned to run for approximately six weeks per well.

Testing will be conducted on the Jetstream No. 3, Jetstream No. 4 and Jetstream No. 5 appraisal wells. Interim results will be released to the market as data are received and verified by the company.

About the Topaz project

The Topaz project is located in northern Minnesota, United States, where Pulsar is the first mover in helium exploration and holds exclusive leases over the project area. Topaz is a primary helium discovery that contains helium-4, helium-3 and CO2 (carbon dioxide). Multiple wells drilled by Pulsar have confirmed a laterally extensive helium-rich gas reservoir beneath the project lands. The continuing Jetstream multiwell appraisal program at Topaz is designed to map out the reservoir's extent, pressure regime and gas composition, which will inform resource estimation and development planning.
