CASCAIS, Portugal, Nov. 11, 2025 (GLOBE NEWSWIRE) --

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) (“Pulsar” or the “Company”), a primary helium development company, is pleased is pleased to announce the successful completion of drilling the Jetstream #3 appraisal well at its flagship Topaz Project in Minnesota, USA, with the drilling operation reaching a total depth (“TD”) of 3,507 feet.

Highlights:

• Successful Drilling: Jetstream #3 reached a total depth (“TD”) of 3,507 feet (1,069 meters) on November 7, 2025, successfully penetrating the entire interpreted helium-bearing interval.
• Commencement of drilling at Jetstream #4: Drill rig relocated and Jetstream #4 successfully ‘spudded’ on Sunday November 9, 2025, as progress begins toward achieving a TD of 3,000 feet (914 metres).
• Strong Pressure: Multiple pressurized gas zones throughout the drilling campaign with a calculated bottom-hole pressure of approximately 960 psi. This strong pressure reading indicates a robust, naturally pressurized, highly charged reservoir at the well location, providing further validation of the Topaz reservoir’s potential.
  • For comparison, Jetstream #1 had a well-head pressure of 185 psi when drilled in 2024, and Jetstream #2 a well-head pressure of 205 psi. 
• Next Steps: Jetstream #3 will, this week, undergo a comprehensive evaluation, with a suite of open-hole wireline logs running to collect detailed geological and petrophysical data. An optical televiewer will be used to image the well-bore wall geology, followed by a proposed controlled flow-testing and pressure build-up program to measure well deliverability.
