Pulsar Helium Encounters Third Gas Zone at Jetstream #5, Prepares February Testing Programme

• Jetstream #5 encountered pressurised gas at approximately 2,857 feet depth with bottom-hole pressure of around 1,292 psi, the highest recorded at Topaz to date.
• Three separate gas zones identified in Jetstream #5 at depths of approximately 837 feet, 1,481 feet, and 2,857 feet.
• Multi-well flow testing programme scheduled to begin in early February 2026, covering Jetstream #3, #4, and #5 wells over approximately six weeks per well.
• Drilling at Jetstream #5 continues towards planned total depth of up to 5,000 feet before rig moves to Jetstream #6, located roughly 2.2 kilometres southwest of Jetstream #1.
• Interim testing results will be released as data is verified by the company.

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) is a primary helium company with two projects: the Topaz helium project in Minnesota, USA, and the Tunu helium project in Greenland. The company holds the first-mover position in helium exploration in both locations, where primary helium occurrences have been identified that are not associated with hydrocarbon production. 

Jetstream #5 Gas Encounters and Drilling Status

Jetstream #5 was spudded on 28 November 2025 as part of the ongoing multi-well appraisal programme at the Topaz Project. During drilling operations, pressurised gas was initially encountered at approximately 837 feet and 1,481 feet. At the 1,481-foot depth, the calculated bottom-hole pressure was approximately 662 psi.

As drilling advanced, additional gas influx was intersected at 2,857 feet, where the calculated bottom-hole pressure reached approximately 1,292 psi. Gas influx has been observed during drilling operations, particularly during pauses in circulation, indicating gas presence within the formation.

The drilling crew returned to work on 3 January following leave that began on 14 December 2025. Drilling operations are continuing towards the anticipated total depth of no more than 5,000 feet. Upon completion of Jetstream #5, the rig will move to drill Jetstream #6, positioned approximately 2.2 kilometres southwest of Jetstream #1.

Multi-Well Flow Testing Programme in February 2026

Pulsar is preparing for a testing programme scheduled to commence in early February 2026. The programme will 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. Flow testing measures gas flow rates and pressures under controlled conditions, whilst pressure build-up testing measures how reservoir pressure recovers after flow periods. These tests provide data on reservoir deliverability, size, and connectivity.

Interim results will be released as data is received and verified by the company.

President and CEO Thomas Abraham-James stated:

"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."

Jetstream #6 Location and Appraisal Programme

The Jetstream #6 appraisal well is located roughly 2.2 kilometres southwest of the Jetstream #1 discovery well. This well location is designed to evaluate the southwestern extent of the helium-bearing reservoir identified in previous drilling.

The Topaz Project is located in northern Minnesota, where Pulsar holds exclusive leases over the project area. Multiple wells drilled by Pulsar have confirmed a helium-rich gas reservoir beneath the project lands containing helium-4, helium-3, and CO2.

The multi-well appraisal programme aims to map the reservoir's extent, pressure regime, and gas composition. This data will inform resource estimation and development planning for the project.

Next Steps

Pulsar will complete drilling at Jetstream #5 and then mobilise the rig to Jetstream #6. The multi-well flow testing programme is scheduled to begin in early February 2026, testing Jetstream #3, #4, and #5 wells over approximately six weeks per well. The company will release interim testing results as data is received and verified. These activities are part of the ongoing appraisal work at the Topaz Project, which will inform resource estimation and future development decisions.
