PULSAR HELIUM REPORTS PRESSURISED GAS ENCOUNTER AT JETSTREAM #5 AND
DOWN-HOLE TESTING CONDUCTED AT JETSTREAM #3 AND #4
Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF), a primary helium exploration and development company, announces that its Jetstream #5 appraisal well at the flagship Topaz Project (Minnesota, USA) has intersected pressurized gas zones. The gas zones were encountered at depths of approximately 837 feet (255 meters) and 1,481 feet (451 meters), with an initial bottom-hole pressure of ~662 psi calculated, and visible gas influx observed during drilling operations. This positive progress result marks the fifth consecutive well in the Jetstream program to encounter gas, further reinforcing confidence in the extent of the helium-rich reservoir. In addition, well-testing has occurred at Jetstream #3 and #4, with data collected now being sent for interpretation.
Highlights:
· Jetstream #5 location: Jetstream #5 is located ~1.8 miles (3 kilometers) northeast of the discovery well (Jetstream #1) at Topaz, significantly extending the project’s appraisal footprint.
· Shallow Pressurized Gas: Gas was encountered at approximately 837 feet (255 meters) and 1,481 feet (451 meters) depth, with a preliminary bottom-hole pressure reading of ~662 psi, indicating a strongly pressurized system even at this early stage of drilling. Gas was visibly seen bubbling through the drilling fluids at surface, confirming active gas flow under pressure.
· Drilling Progress: The well is being drilled using continuous HQ core drilling (large 63.5 mm diameter core) to maximize geological sample recovery while maintaining efficient progress. Around-the-clock drilling (24-hour operations with rotating crews) is ongoing as Jetstream #5 advances toward its target depth of 5,000 feet (1,524 meters).
· Consistent Success: All five Jetstream appraisal wells drilled to date have encountered pressurized gas (a 100% success rate). This consistent success across the program underscores the continuity of the helium-bearing reservoir and the potential of the Topaz Project.
· Well-Testing: Jetstream #3 and #4 had down-hole logging conducted, with data sent for interpretation. The data collected includes formation microresistivity imaging, dipole sonic, resistivity, gamma, and neutron density logs.
Thomas Abraham-James, President & CEO of Pulsar, commented:
“To encounter pressurized gas once again in Jetstream #5 is both validating and exciting for our team. With all five Jetstream wells confirming gas, we now have a consistent track record that underscores the pervasive nature of the helium reservoir at Topaz. In particular, seeing a gas influx at such a shallow depth in Jetstream #5 is highly encouraging, it suggests the gas column is extensive and the reservoir pressure is robust across the field. Each successful well brings us one step closer to our goal of establishing Topaz as a major primary helium source in North America. We will continue to advance the program diligently, collecting high-quality data from core samples and forthcoming tests to guide the next phases of this project’s development.”
Jetstream #5 Well Update
Jetstream #5, the third well in Pulsar’s current multi-well appraisal program at Topaz, was spudded on November 28, 2025. The well drilled through overburden and into the prospective formation, reaching significant gas shows at 837 and 1,481 feet depth (255 and 451 meters, respectively). Upon penetrating these zones, pressurized gas entered the wellbore, with crew members observing a noticeable influx of gas bubbling through the drilling mud at the surface. The preliminary calculated bottom-hole pressure at 1,481 feet is approximately 662 psi, a strong early indicator of a pressurized reservoir. This initial pressure measurement may be adjusted as drilling continues and final downhole pressure readings are obtained deeper in the well.
Drilling operations at Jetstream #5 are ongoing on a 24-hour schedule, with rotating crews ensuring continuous progress. The well has already surpassed the depth of the initial gas encounter and is proceeding toward the planned TD of 5,000 feet (1,524 m). Pulsar is utilizing HQ core drilling methodology for this well, which involves cutting a large-diameter core (~63.5 mm) to retrieve continuous rock samples. This approach is yielding abundant physical core for geological analysis while maintaining efficient penetration rates. Notably, gas continues to percolate from the formation during drilling, gas bubbling and pressure are evident in the returns, especially when pausing to add drill pipe, indicating sustained gas presence in the formation. These observations suggest that the reservoir remains pressurized as the well drills deeper, an encouraging sign as Jetstream #5 progresses through the stratigraphy.
As with the previous Topaz appraisal wells, once Jetstream #5 reaches total depth and drilling is concluded, the Company will initiate a comprehensive evaluation program. This will likely include open-hole wireline logging, flow testing, and pressure build-up analysis across the encountered zones, alongside laboratory analysis of gas samples and core material. (In the ongoing program, Pulsar has been sequencing well completion and testing activities to optimize costs and efficiency; for example, testing of the Jetstream #3 and #4 wells will be conducted together.) The data collected from Jetstream #5, in combination with results from Jetstream #3 and #4, will further delineate the reservoir’s properties and help quantify the helium resource in place. Updates on these appraisal results and any testing outcomes will be provided in due course.
Jetstream #3 and Jetstream #4 Well-Testing Update
In parallel with drilling operations at Jetstream #5, Pulsar completed a suite of down-hole wireline tests at Jetstream #3 and Jetstream #4 on December 6-7, 2025. These activities form an important part of the ongoing appraisal program and will support detailed reservoir characterization ahead of planned flow testing. The down-hole wireline tests were conducted by Extreme Wireline, Inc. from Utah, and consisted of formation microresistivity imaging, dipole sonic, resistivity, gamma, and neutron density logs. The data will now be sent to experts for evaluation and interpretation to further our understanding of the reservoir.
The next phase of appraisal work at the wells will consist of flow testing, gas sample collection for laboratory analysis (for all gases, including helium-3), and pressure build up testing. This testing program is expected to occur in January 2026, subject to equipment scheduling. Results from these tests will provide key inputs for the next iteration of the Topaz resource model and will help quantify the production potential of each well.
About the Topaz Project
The Topaz Project is located in northern Minnesota, USA, where Pulsar is the first mover in helium exploration and holds exclusive leases over the project area. Topaz is a primary helium discovery that contains helium-4, helium-3 and CO2, not associated with primarily hydrocarbon production. Multiple wells drilled by Pulsar have confirmed a laterally extensive helium-rich gas reservoir beneath the project lands. Notably, two wells drilled at Topaz, both with high helium concentrations averaging 8.1% in Jetstream #1 and 5.6% in Jetstream #2, measured during flow-testing, and the presence of helium-3 (a rare and valuable isotope) has been confirmed in gas samples taken from Jetstream #1. These results appear to indicate a high-quality helium resource. The ongoing Jetstream multi-well appraisal program at Topaz is designed to map out the reservoir’s extent, pressure regime, and gas composition, which will inform resource estimation and development planning.
