PULSAR HELIUM REPORTS PRESSURISED GAS ENCOUNTER AT JETSTREAM #4 AS APPRAISAL DRILLING ADVANCES

Pulsar Helium Inc.'s Jetstream No. 4 well commenced drilling on Nov. 9 and has encountered pressurized gas with a calculated bottom-hole pressure of approximately 674 pounds per square inch (psi) at a depth of 1,457 feet (444 metres). This further underscores a highly charged gas reservoir and the well continues to progress to a total anticipated depth of 3,000 feet (914 metres). All Jetstream wells have encountered gas, a 100-per-cent success rate.

Highlights:

• Location: Jetstream No. 4 is located 0.4 mile (approximately 600 metres) south of Jetstream No. 3 and 0.1 mile (approximately 250 metres) north of Jetstream No. 1 at the Topaz helium project in Minnesota.
• Pressurized gas zones: Jetstream No. 4 intersected gas-bearing intervals at approximately 1,187 to 1,277 feet (362 to 389 metres) and between 1,327 and 1,437 feet (between 404 and 438 metres) depth, with bottom-hole pressure estimated at approximately 674 psi at 1,457 feet (444 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 is another strong pressure reading, complementing the 960-pound-per-square-inch bottom-hole pressure calculated in Jetstream No. 3.
• Advancing drilling operations: Jetstream No. 4 has a planned total depth of approximately 3,000 feet (914 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: Drilling Jetstream No. 4 is continuing, and, upon reaching total depth (TD), both Jetstream No. 3 and Jetstream No. 4 will undergo comprehensive evaluation. A suite of open-hole wireline logs will be run to collect detailed geological and petrophysical data, an optical televiewer will be used to image the wellbore wall geology, followed by a proposed controlled flow-testing and pressure build-up 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 another zone of pressurized gas at Jetstream No. 4 is a highly encouraging continuation of what we are seeing across the field. A [approximately] 674-pound-per-square-inch 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. With Jetstream No. 4 advancing toward total depth, we are excited to see what else it may show. 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. It is an exciting phase of work as we progress Topaz toward our objective of becoming a major primary helium project in North America."

Jetstream No. 4 well update

Jetstream No. 4, the second well in Pulsar's new multiwell program at Topaz, was spudded on Nov. 9. The well encountered gas shows between 1,187 and 1,277 feet (between 362 and 389 metres) and between 1,327 and 1,437 feet (between 404 and 438 metres) depth. Upon penetrating these intervals, a significant influx of gas was observed, and bottom-hole pressure was calculated at approximately 674 psi at 1,457 feet (444 metres). 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 Jetstream No. 4 well continues to advance to its TD of 3,000 feet (914 metres), with the main gas zone interpreted to be intersected at 1,700 feet (518 metres).

Drilling is continuing on a 24-hour schedule with rotating crews. Jetstream No. 4 has currently surpassed 1,457 feet (444 metres) of depth and continues toward the planned total depth of 3,000 feet (914 metres). 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 continues to percolate and bubble through the drill mud under notable pressure while drilling and becomes more evident when a new drill pipe connection is made.

Once Jetstream No. 4 reaches total depth, Pulsar will initiate a comprehensive downhole evaluation program across both newly drilled appraisal wells. The decision was made to test both wells simultaneously to reduce mobilization costs and therefore a more efficient deployment of capital. The testing will include 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 and Jetstream No. 4 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 Pulsar's news release dated Oct. 1, 2025). The company is eager to see if Jetstream No. 3 and Jetstream No. 4 exhibit 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 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). Jetstream No. 3 reached TD on Nov. 7 and during drilling the calculated bottom-hole pressure was approximately 960 psi, with down-hole testing and gas sampling to occur after completion of Jetstream No. 4. 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 to 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 continuing multiwell drilling campaign will build on these results to expand Pulsar's understanding of the reservoir and advance Topaz toward development.
