Pulsar Helium Inc. (AIM: PLSR, TSX-V: PLSR, OTCQB: PSRHF; FRA: Y3K) reports a spectacular interim result from the ongoing drilling campaign at its Topaz Helium Project in Minnesota, USA: 950 meters from the Jetstream #1 well, the current Jetstream #3 well encountered gas at a depth of approximately 660 meters with a pressure of nearly 1,000 psi (approximately 68 bar). This is by far the highest pressure measured on the project to date and a clear indication of a highly charged gas reservoir. The measured pressure at a shallower depth is already five times higher than the previously highest pressure measured at the bottom of Jetstream #2 well, where a pressure of 205 psi was recorded at a depth of 1,718 meters. This new discovery impressively confirms the company’s geological model. The target depth for Jetstream #3 is expected to be 1,070 meters.
Strong Pressure Level Confirms Gas Potential of the Reservoir
The Jetstream #3 well was spudded on October 17, 2025, and is located approximately 950 meters northeast of the previous Jetstream #1 well. Gas was already observed in the drilling mud during ongoing operations – a clear indication of active inflow from the formation.
According to Pulsar Helium, two gas-bearing zones were identified at depths of approximately 523 and 621 meters. At the time of publication, the measured bottom-hole pressure was approximately 960 psi at a drilling depth of 661 meters. For comparison: Jetstream #1 showed a pressure of only 185 psi in 2024, and Jetstream #2 reached 205 psi.
These significantly higher values indicate a highly charged system and underscore the potential of the deposit. The planned final depth for Jetstream #3 is approximately 1,070 meters. Currently, drilling is continuing using core drilling with a diameter of 96 millimeters – an approach that allows for a particularly high sample yield.
CEO Abraham-James: “a Significant Step for Pulsar Helium”
Thomas Abraham-James, President and CEO of Pulsar Helium, described the results as a milestone for the project:
“The measured gas pressure of nearly 1,000 psi is a strong signal for the energy of the reservoir at this location. This not only confirms our geological model but also strengthens our confidence in the continuity of the helium system at Topaz.”
After reaching its final depth, Jetstream #3 will undergo a comprehensive evaluation and testing phase. This includes well logging, flow and pressure build-up tests, as well as detailed laboratory analyses of core and gas samples to determine composition and helium content. Special attention is being paid to the Helium-3 isotope, which has already been detected in previous wells and is rare worldwide.
Topaz: Potential for Primary Helium Production in North America
The Topaz Project in northern Minnesota is considered one of the few known primary helium occurrences not associated with hydrocarbons. Pulsar Helium holds exclusive exploration rights in the area and is a first mover there.
The two previous wells, Jetstream #1 (5,100 feet) and Jetstream #2 (5,638 feet), had already fully penetrated the helium-bearing reservoir. During a flow test in August 2025, Jetstream #1 achieved a maximum gas flow rate of approximately 1.3 million cubic feet per day, with a helium content of 7 to 8% Helium-4. In addition, Helium-3 was identified in measurable quantities – a geologically and economically remarkable discovery.
With Jetstream #3, Pulsar is now commencing the first well of a planned multi-stage drilling campaign, which aims to refine the reservoir model and establish the basis for a future development decision.
Strategic Progress for Pulsar Helium
The ongoing work at Topaz is part of the company’s long-term development strategy, which aims to establish independent helium production in North America. Due to its physical properties, helium is considered a critical raw material for high-tech and energy sectors – including applications in aerospace, the semiconductor industry, and medical imaging.
With the results to date from Jetstream #1, #2, and now #3, Pulsar Helium confirms the existence of an overpressured, helium-rich reservoir, which could be among the most promising known occurrences in the USA.
Conclusion:
With the discovery of nearly 1,000 psi gas pressure in the Jetstream #3 well, Pulsar Helium confirms its underlying geological model for the Topaz helium deposit. Pulsar plans up to 9 additional wells at wide intervals in its ongoing campaign. The preliminary results confirm the potential of a large, overpressured reservoir and strengthen the company’s position as one of the leading exploration players in the North American helium sector. We eagerly await the upcoming measurements of helium concentration in the Jetstream #3 well.
