Jetstream #3 Well Reaches Total Depth as Topaz Drilling Programme Continues

• Jetstream #3 well completed at 3,507 feet (1,069 metres) on 7 November 2025, penetrating the entire interpreted helium-bearing interval
• Bottom-hole pressure calculated at approximately 960 psi, compared to wellhead pressures of 185 psi at Jetstream #1 and 205 psi at Jetstream #2
• Drilling commenced at Jetstream #4 on 9 November 2025, targeting total depth of 3,000 feet (914 metres)
• Open-hole wireline logging, optical televiewer imaging and controlled flow testing scheduled for Jetstream #3 this week
• Active drilling campaign of up to 10 wells underway to support updated resource estimate and Preliminary Economic Assessment targeted for first half of 2026

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) is a helium development company with two projects: the Topaz helium project in Minnesota, USA, and the Tunu helium project in Greenland. The company has identified primary helium occurrences not associated with hydrocarbon production at both locations. 

Drilling Operations at Topaz Project

Jetstream #3 reached total depth of 3,507 feet on 7 November 2025. The well penetrated the entire interpreted helium-bearing interval and encountered multiple pressurised gas zones during drilling operations. The well successfully completed its drilling phase as planned.

Following completion of Jetstream #3, the drilling rig was relocated to the Jetstream #4 location. Drilling at Jetstream #4 commenced on 9 November 2025, with operations targeting a total depth of 3,000 feet (914 metres). The rig mobilisation between locations was completed within two days of finishing Jetstream #3.

The current drilling campaign includes up to 10 wells intended to define the geometry, extent and productivity of the helium-bearing reservoir at Topaz. Field operations are ongoing as the company works towards completing an updated resource estimate and a Preliminary Economic Assessment in the first half of 2026.

Pressure Data from Jetstream #3

The bottom-hole pressure at Jetstream #3 was calculated at approximately 960 psi. This measurement differs from the wellhead pressures previously recorded: Jetstream #1 had a wellhead pressure of 185 psi when drilled in 2024, whilst Jetstream #2 recorded a wellhead pressure of 205 psi. These measurements were taken at different points in the well system.

The drilling operation at Jetstream #3 encountered multiple pressurised gas zones throughout the campaign. The pressure reading indicates a naturally pressurised reservoir at this well location.

President and CEO Thomas Abraham-James stated that,

"Initial bottom-hole pressure readings surpass expectation and reinforce our belief in the huge potential offered by this incredible multi-commodity gas discovery."

The pressure data from Jetstream #3 forms part of the subsurface information being collected across the drilling programme. This data will be used in the resource update and economic assessment work scheduled for 2026, alongside results from other wells in the campaign.

Testing Programme and Timeline

Jetstream #3 will undergo evaluation this week beginning with open-hole wireline logging to collect geological and petrophysical data across the helium-bearing interval. An optical televiewer will be deployed to image the wellbore wall geology, followed by controlled flow testing and pressure build-up tests to measure well deliverability.

The wireline logging will provide measurements of rock properties, fluid content and reservoir characteristics. The flow testing programme is designed to determine production rates under controlled conditions and observe how reservoir pressure responds over time. These test results will provide data for reservoir modelling and economic evaluation.

The company plans to complete an updated resource estimate for Topaz and conduct a Preliminary Economic Assessment during the first half of 2026.

Abraham-James stated that,

"With the drilling of Jetstream #4 underway and down-hole testing soon to commence at Jetstream #3, momentum continues to build at Topaz as we advance our drilling campaign and move steadily towards defining what we believe to be one of North America's most significant primary helium discoveries."

Project Status

Pulsar Helium has completed drilling at Jetstream #3 and commenced operations at Jetstream #4 as part of its ongoing appraisal programme at the Topaz Project. The company recorded bottom-hole pressure of approximately 960 psi at Jetstream #3 and will conduct comprehensive testing at that well this week. With up to 10 wells planned in the current campaign, the company is working towards completing an updated resource estimate and Preliminary Economic Assessment in the first half of 2026.
