CASCAIS, Portugal, Jan. 28, 2026 (GLOBE NEWSWIRE) — Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) (“Pulsar” or the “Company”), a primary helium company, is pleased to announce that drilling of Jetstream #5 at the Company’s flagship Topaz Project in Minnesota, USA has been completed, drilled to a total depth (TD) of 3,839 feet (1,170 meters). As reported earlier (news releases January 9, 2026 & December 8, 2025) multiple pressurized gas influxes were encountered at depths of 837 feet (255 meters), 1,481 feet (451 meters) and 2,857 feet (871 meters). The bottom-hole pressure at 2,857 feet is estimated at ~1,292 pounds per square inch (psi), the highest recorded to date at Topaz. The drill rig has now mobilized to Jetstream #6 and commenced drilling on January 27, 2026.

Summary of Jetstream #5

Article content

The Jetstream #5 appraisal well has been successfully completed to a total depth of 3,839 feet, further advancing the Company’s multi-well appraisal program. During drilling, Jetstream #5 intersected multiple pressurized gas zones, with initial gas encountered at approximately 837 feet, followed by a second gas-bearing interval at approximately 1,481 feet, where a preliminary bottom-hole pressure of approximately 662 psi was calculated. As drilling progressed, an additional deeper gas influx was intersected at approximately 2,857 feet, where the calculated bottom-hole pressure increased significantly to approximately 1,292 psi, representing the highest pressure recorded to date at the Topaz Project. Gas influx was consistently observed during drilling operations, particularly during pauses in circulation, indicating sustained gas presence and a strongly pressurized reservoir system. While removing the drill string from the well at total depth, difficulties were encountered, and 1239 ft of drill string was left in the well. The Company is evaluating all options and plans to return to Jetstream #5 in April of this year to retrieve or bypass the segment of stuck drill string and allow the full logging and flow testing of the entire 3,839 ft of formation.

New Appraisal Well Jetstream #6

Article content

Drilling of the Jetstream #6 appraisal well commenced January 27^th, with a designed TD of 3,000 feet (914 meters), with the possibility of deepening to 5,000 feet (1,524 meters). The appraisal well is located 1.3 miles (2.1 kilometers) to the southwest of Jetstream #1, another considerable step out with the intention of increasing the size of the Topaz resource.

Flow Testing and Pressure Build-Up Program

Article content

Pulsar is preparing to move forward with a coordinated testing program on the Jetstream #3 and #4 anticipated to commence in late February 2026. The program is expected to consist of a period of flow testing, followed by a period of pressure build-up. The test is planned to run for approximately six weeks per well. Pulsar will also be conducting as gas sample program during the flow period at the direction of Peter Barry. Interim results will be released to the market as data is received and verified by the Company.

About the Topaz Project

Article content

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, not associated with primarily hydrocarbon production. Multiple wells drilled by Pulsar have confirmed a laterally extensive helium-rich gas reservoir beneath the project lands. These results appear to indicate a high-quality helium resource. 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.
