PULSAR HELIUM REPORTS ADDITIONAL HIGH-PRESSURE GAS ENCOUNTER AT JETSTREAM #5 AND OUTLINES UPCOMING TESTING PROGRAM
Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF), a primary helium company, is pleased to announce that its Jetstream #5 appraisal well at the flagship Topaz Project (Minnesota, USA) has encountered an additional pressurized gas influx at approximately 2,857 feet (871 meters) 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 meters) and 1,481 feet (451 meters). Drilling of Jetstream #5 is ongoing and will continue toward a planned total depth of up to 5,000 feet (1,524 meters).
Upon completion of Jetstream #5, the drilling rig will mobilize to the next appraisal well, Jetstream #6, located roughly 2.2 kilometers southwest of the discovery well (Jetstream #1). In addition, preparations are underway for a multi-well flow testing program slated to commence in early February, 2026. This program will consist of flow testing followed by pressure build-ups to evaluate the Jetstream #3, #4, and #5 wells. A six-week test period per well is expected. Pulsar will announce interim results from the Topaz testing campaign as data is received and verified by the Company.
Highlights:
• Additional High-Pressure Gas: Jetstream #5 encountered additional high-pressure gas at ~2,857 feet depth, with a bottom-hole pressure of approximately 1,292 psi (the highest observed at Topaz so far).
• Multiple Gas Zones: Prior pressurized gas encountered at ~837 feet and ~1,481 feet in Jetstream #5.
• Continuing to Total Depth: Drilling is continuing at Jetstream #5, targeting a total depth of no more than 5,000 feet.
• Next Well Mobilization: Upon finishing Jetstream #5, the rig will move to drill Jetstream #6, located ~2.2 km southwest of the Topaz discovery well (Jetstream #1).
• Upcoming Testing Program: A combined flow testing and pressure build-up program is anticipated to begin in early February 2026, over approximately six weeks per well. The campaign will cover Jetstream wells #3, #4, and #5, with interim results to be shared with the market once data is collected and verified.
Jetstream #5 Update
Jetstream #5 was spudded on November 28, 2025, as part of Pulsar’s ongoing multi-well 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 psi (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 psi. Gas influx has been observed during drilling operations, particularly during pauses in circulation, indicating sustained gas presence within the formation.
Jetstream #5 is being drilled on a continuous basis, with the crew returning to work on January 3 after commencing leave on December 14, 2025. Drilling operations remain ongoing, with the well advancing toward its anticipated total depth of no more than 5,000 feet. Upon finishing Jetstream #5, the rig will move to drill Jetstream #6, located ~2.2 km southwest of Jetstream #1.
Upcoming Testing Program
Pulsar is preparing for a coordinated testing program anticipated to commence in early February 2026. The program is expected to utilise flow testing and pressure build-up equipment and is planned to run for approximately six weeks per well.
Testing will be conducted on the Jetstream #3, Jetstream #4, and Jetstream #5 appraisal wells. Interim results will be released to the market as data is received and verified by the Company.
About the Topaz Project
The Topaz Project is located in northern Minnesota, USA, 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. Multiple wells drilled by Pulsar have confirmed a laterally extensive helium-rich gas reservoir beneath the project lands. The ongoing Jetstream multi-well 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.
