Pulsar Helium Inc. (LSE:PLSR) has confirmed its highest-pressure gas encounter so far at the Jetstream #5 appraisal well within the Topaz Project in Minnesota, marking another technical milestone for the helium-focused explorer.
The new gas influx was intersected at approximately 2,857 feet and is estimated to carry a bottom-hole pressure of about 1,292 psi. This exceeds all previous pressure readings across the project and adds to multiple gas-bearing zones already identified at shallower levels within the Jetstream well sequence.
Drilling operations at Jetstream #5 are ongoing, with the company targeting a total depth of up to 5,000 feet. Once completed, the drilling rig is expected to move directly to Jetstream #6, continuing the step-out appraisal strategy at Topaz.
In parallel, the company is preparing a multi-well flow and pressure build-up testing program covering Jetstream wells #3, #4, and #5. Scheduled to begin in early February 2026, the campaign is designed to improve understanding of reservoir continuity, pressure dynamics, and gas composition. The results are expected to support future resource estimates and inform longer-term development planning at the Topaz helium asset.
