Pulsar Helium Encounters Pressurised Gas at Jetstream #4 Well

• Jetstream #4 encountered pressurised gas with calculated bottom-hole pressure of 674 psi at 1,457 feet depth
• Two gas-bearing zones intersected between 1,187-1,277 feet and 1,327-1,437 feet depth
• All four Jetstream wells have encountered gas during the appraisal programme
• Testing programme planned for Jetstream #3 and #4 will include wireline logging, flow testing, and laboratory analysis
• Laboratory analysis will assess helium concentrations and test for helium-3 presence

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) is a primary helium development company with two project locations. The company holds exclusive leases at its Topaz project in northern Minnesota and the Tunu project in Greenland. Both projects feature primary helium occurrences not associated with hydrocarbon production.

Jetstream #4 Pressurised Gas Encounter and Bottom-Hole Pressure Results

The Jetstream #4 well commenced drilling on 9 November and has intersected two gas-bearing intervals. The first interval occurs between 1,187-1,277 feet and the second between 1,327-1,437 feet. At 1,457 feet depth, bottom-hole pressure was calculated at approximately 674 psi. This pressure reading is subject to change as drilling continues to the planned total depth of 3,000 feet, with final bottom-hole and wellhead pressures to be obtained at that depth.

The 674 psi pressure reading at Jetstream #4 follows the 960 psi bottom-hole pressure recorded at Jetstream #3.

Thomas Abraham-James, President and CEO, stated:

"A 674 psi pressure reading at this relatively shallow depth reinforces the strength of the reservoir and further validates the geological model built from the earlier Jetstream wells."

The well is currently at 1,457 feet depth with the main gas zone interpreted to be at 1,700 feet. Drilling operations continue toward the 3,000-foot total depth target.

Drilling Progress and Gas Zone Intersections

Jetstream #4 is located 0.4 miles south of Jetstream #3 and 0.1 miles north of Jetstream #1 at the Topaz helium project. The well is advancing on a 24-hour drilling schedule with rotating crews and has currently surpassed 1,457 feet as it progresses toward 3,000 feet total depth. The company is using continuous HQ core drilling methods with a 3.8-inch diameter bit to extract core samples measuring approximately 63.5 millimetres.

Drilling personnel have observed gas bubbling in the drilling mud returns at surface during pipe connections, indicating gas influx from the formation during operations. The coring method provides physical samples for geological analysis whilst maintaining drilling progress.

All four Jetstream wells drilled to date have encountered gas during the appraisal programme. Jetstream #1 reached total depth of 5,100 feet in January 2025, while Jetstream #2 was completed on 1 February 2025 at 5,638 feet. Jetstream #3 reached total depth on 7 November with a calculated bottom-hole pressure of 960 psi.

Comprehensive Testing and Laboratory Analysis Plans

Upon reaching total depth, the company will conduct a testing programme across both Jetstream #3 and Jetstream #4. The decision to test both wells simultaneously aims to reduce mobilisation costs through a single deployment of testing equipment and personnel.

The testing programme includes open-hole wireline logging to measure formation properties, an optical televiewer to image the wellbore wall geology, and flow testing with pressure build-up analysis to measure well deliverability. These measurements will provide data on reservoir characteristics and production potential.

Core and gas samples from both wells will undergo laboratory analysis to determine gas composition and helium concentrations. The analysis will include testing for helium-3, a rare isotope previously detected in Jetstream #1. Abraham-James commented: "Our team is focused on collecting the highest-quality data possible as we prepare for wireline logging, flow-testing, and full laboratory analysis, including assays for helium-3." In August 2025, Jetstream #1 was flow-tested and delivered a peak gas flow rate of approximately 1.3 million cubic feet per day with sustained flow of 7-8% helium content.

Looking Forward

Pulsar Helium continues its multi-well drilling campaign at the Topaz project. As Jetstream #4 progresses toward 3,000 feet total depth, upcoming milestones include reaching total depth, commencing testing programmes on Jetstream #3 and #4, conducting wireline logging and optical imaging, performing flow testing, and receiving laboratory analysis results on helium concentrations and helium-3 presence. The data from these activities will inform future resource estimates for the project.
