PULSAR HELIUM ANNOUNCES JETSTREAM #3 ENCOUNTERS GAS WITH NEAR-1,000 PSI BOTTOM-HOLE PRESSURE

Pulsar Helium Inc. has achieved a major milestone at its flagship Topaz project in Minnesota. The Jetstream No. 3 well commenced drilling on Oct. 17 and has encountered pressurized gas with a calculated bottom-hole pressure of approximately 960 pounds per square inch, underscoring a highly charged gas reservoir. This development marks a significant step forward in the continuing drilling campaign, building on the success of the earlier Jetstream No. 1 and No. 2 wells and confirming the continuity of the helium-rich system.

Highlights:

• Location: Jetstream No. 3 is located 0.6 mile (approximately 950 metres) northeast of Jetstream No. 1 at the Topaz helium project in Minnesota.
• Pressurized gas zones: Jetstream No. 3 intersected two gas-bearing intervals at approximately 1,717 (523 metres) and 2,036 feet (621 metres) depth, with bottom-hole pressure estimated at approximately 960 psi at 2,167 feet (661 metres), which is the depth at the time of writing this news release (and is subject to change when the hole is deepened and final bottom hole and wellhead pressures are obtained when total depth is achieved). This strong pressure reading indicates a robust, pressurized reservoir at the well location, a major validation of the Topaz field's potential. For comparison, Jetstream No. 1 had a bottom-hole pressure of 185 psi when drilled in 2024 and Jetstream No. 2 had a bottom-hole pressure of 205 psi when drilled in 2025.
• Advancing drilling operations: Jetstream No. 3 has a planned total depth of approximately 3,500 feet (1,067 metres) and is being drilled using the coring method with a hole diameter of 3.8 inches (96 millimetres).
• Visible gas: Drilling personnel observed gas bubbling in the drilling mud returns at surface during pipe connections. This indicates an active gas influx from the formation while drilling is under way.
• Next steps, testing and analysis: Upon reaching total depth, Jetstream No. 3 will undergo comprehensive evaluation. A suite of open-hole wireline logs will be run to collect detailed geological and petrophysical data, and an optical televiewer will be used to image the wellbore wall geology, followed by a proposed controlled flow testing and pressure buildup program to measure well deliverability. All core and gas samples will be sent for laboratory analysis to determine gas composition and helium concentrations, including testing for the rare helium-3 isotope discovered in Jetstream No. 1.

Thomas Abraham-James, president and chief executive officer of Pulsar, commented: "Encountering such strong gas pressure at Jetstream No. 3 is extremely encouraging for our team. A near-1,000-psi bottom-hole pressure suggests we have a highly charged reservoir at this location. This outcome not only validates the geological model we built from Jetstream No. 1 and No. 2 but also boosts our confidence as we continue drilling and begin the testing phase. We will proceed carefully to collect comprehensive data, including gas samples for lab analysis, to fully understand the reservoir's characteristics. It's an exciting milestone for Pulsar as we advance Topaz toward becoming a leading primary helium project in North America."

Jetstream No. 3 well update

Jetstream No. 3, the first well in Pulsar's new multiwell program at Topaz, was spudded on Oct. 17. The well encountered a gas show at approximately 1,717 feet vertical depth and again at approximately 2,036 feet, within 100 vertical feet of the interpreted depth of the known helium-bearing zone identified in Jetstream No. 1. Upon penetrating these intervals, a significant influx of gas was observed, and bottom-hole pressure was calculated at approximately 960 psi at 2,167 feet. This pressure level is a strong indicator of a pressurized reservoir but is subject to change as the hole is deepened and final bottom-hole and wellhead pressure readings are obtained. The presence of pressurized gas at such depth is a major milestone for the project, confirming that the targeted formations are charged with gas as anticipated.

Drilling is continuing on a 24-hour schedule with rotating crews. Jetstream No. 3 has currently surpassed 2,167 feet of depth and continues toward the planned total depth of 3,500 feet. The well is being drilled using continuous HQ core drilling (large-diameter core of approximately 63.5 millimetres) to maximize sample recovery. This drilling method is providing abundant physical core samples for geological analysis while maintaining efficient progress. Notably, gas is bubbling through the drill mud while drilling and becomes more evident when a new drill pipe connection is made.

Once Jetstream No. 3 reaches total depth, Pulsar will initiate a comprehensive downhole evaluation program. This includes a suite of open-hole wireline logs, flow testing and pressure buildup analysis on the well. Concurrent with field testing, core and gas samples from Jetstream No. 3 will undergo thorough laboratory analysis. The lab program will determine the gas composition and exact helium content of the samples. Importantly, the analysis will include assays for helium-3, a rare isotope of helium, given that helium-3 was previously detected in the Topaz reservoir at notable levels (refer to news release dated Oct. 1, 2025). The company is eager to see if Jetstream No. 3 exhibits a similar helium-3 signature, which would further underscore the unique character and value of the Topaz helium discovery.

About the Topaz project

The Topaz project is located in northern Minnesota, United States, where Pulsar is the first mover and holds exclusive leases. Drilling at the Jetstream No. 1 appraisal well reached a total depth (TD) of 5,100 feet (1,555 metres) in January, 2025, successfully penetrating the entire interpreted helium-bearing reservoir and beyond. Drilling of the Jetstream No. 2 appraisal well was completed on Feb. 1, 2025, reaching a TD of 5,638 feet (1,718 metres). In August, 2025, the Jetstream No. 1 well was successfully flow tested using a wellhead compressor, delivering a peak gas flow rate of approximately 1.3 million cubic feet per day with a sustained flow of 7 tp 8 per cent helium (as helium-4). Recent laboratory analyses have also confirmed the presence of helium-3 in measurable concentrations, representing one of the highest naturally occurring helium-3 values publicly reported in a terrestrial gas reservoir. The forthcoming multiwell drilling campaign will build on these results to expand Pulsar's understanding of the reservoir and advance Topaz toward development.
