CASCAIS, Portugal, Oct. 30, 2025 (GLOBE NEWSWIRE) --
Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) (“Pulsar” or the “Company”), a leading helium exploration and development company, is pleased to announce a major milestone at its agship Topaz Project in Minnesota.
The Jetstream #3 well commenced drilling on October 17 and has encountered pressurized gas with a calculated bottom-hole pressure of approximately 960 psi, underscoring a highly charged gas reservoir. This development marks a signicant step forward in the ongoing drilling campaign, building on the success of the earlier Jetstream
#1 and #2 wells and conrming the continuity of the helium-rich system.

Highlights:
Location: Jetstream #3 is located 0.6 miles (~950 meters) northeast of Jetstream #1 at the Topaz heliumAIM: PLSR | TSXV: PLSR | OTCQB: PSRHFPulsar Helium Inc

project in Minnesota.
Pressurized gas zones: Jetstream #3 intersected two gas-bearing intervals at approximately 1,717 (523 meters) and 2,036 feet (621 meters) depth, with bottom-hole pressure estimated at ~960 psi at 2,167 feet (661 meters), which is the depth at the time of writing this news release (and is subject to change when the hole is deepened and nal bottom hole and well-head 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 eld’s potential. For comparison, Jetstream #1 had a bottom hole pressure of 185 psi when drilled in 2024, and Jetstream #2 had a bottom hole pressure of 205 psi when drilled in 2025.

Advancing drilling operations: Jetstream #3 has a planned total depth of ~3,500 feet (1,067 meters) and is being drilled using the coring method with a hole diameter of 3.8 inches (96 mm).

Visible gas: Drilling personnel observed gas bubbling in the drilling mud returns at surface during pipe connections. This indicates an active gas inux from the formation while drilling is underway.

Next steps, testing and analysis: Upon reaching total depth, Jetstream #3 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 well-bore wall geology, followed by a proposed controlled ow- 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 #1.

Thomas Abraham-James, President & CEO of Pulsar, commented:
“Encountering such strong gas pressure at Jetstream #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 #1 and #2, but also boosts our condence 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 #3 Well Update
Jetstream #3, the rst well in Pulsar’s new multi-well program at Topaz, was spudded on October 17 . The well encountered a gas show at ~1,717 feet vertical depth and again at ~2,036 feet, within 100 vertical feet of the thAIM: PLSR | TSXV: PLSR | OTCQB: PSRHFPulsar Helium Inc

interpreted depth of the known helium-bearing zone identied in Jetstream #1. Upon penetrating these intervals, a signicant inux of gas was observed, and bottom-hole pressure was calculated at ~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 well-head pressure readings are obtained. The presence of pressurized gas at such depth is a major milestone for the project, conrming that the targeted formations are charged with gas as anticipated.

Drilling is ongoing on a 24-hour schedule with rotating crews. Jetstream #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 ~63.5 mm) to maximize sample recovery. This drilling method is providing abundant physical core samples for geological analysis while maintaining ecient 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 #3 reaches total depth, Pulsar will initiate a comprehensive downhole evaluation program. This includes a suite of open-hole wireline logs, ow testing and pressure build-up analysis on the well. Concurrent with field testing, core and gas samples from Jetstream #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 October 1, 2025). The Company is eager to see if Jetstream #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, USA, where Pulsar is the rst mover and holds exclusive leases.
Drilling at the Jetstream #1 appraisal well reached a total depth (“TD”) of 5,100 feet (1,555 meters) in January 2025, successfully penetrating the entire interpreted helium-bearing reservoir and beyond. Drilling of the Jetstream #2 appraisal well was completed on February 1, 2025, reaching a TD of 5,638 feet (1,718 meters). In August 2025, the
Jetstream #1 well was successfully ow-tested using a wellhead compressor, delivering a peak gas ow rate of approximately 1.3 million cubic feet per day with a sustained ow of 7–8% helium (as helium-4). Recent laboratory analyses have also conrmed 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 multi-well drilling campaign will build on these results to expand Pulsar’s understanding of the reservoir and advance Topaz toward development.

potential acquisition of property interests in the future. Un-risked Contingent and Prospective Helium Volumes
have been dened at the Topaz Project. However, estimating helium volumes is subject to signicant uncertainties
associated with technical data and the interpretation of that data, future commodity prices, and development and
operating costs. There can be no guarantee that the Company will successfully convert its helium volume to
reserves and produce that estimated volume. Estimates may alter signicantly or become more uncertain when
new information becomes available due to for example, additional drilling or production tests over the life of eld.
As estimates change, development and production plans may also vary. Downward revision of helium volume
estimates may adversely aect the Company's operational or nancial performance.
Helium volume estimates are expressions of judgement based on knowledge, experience and industry practice.
These estimates are imprecise and depend to some extent on interpretations, which may ultimately prove to be
inaccurate and require adjustment or, even if valid when originally calculated, may alter signicantly when new
information or techniques become available. As further information becomes available through additional drilling
and analysis the estimates are likely to change. Any adjustments to volume could aect the Company's exploration
and development plans which may, in turn, aect the Company's performance. The process of estimating helium
resources is complex and requires signicant decisions and assumptions to be made in evaluating the reliability of
available geological, geophysical, engineering, and economic date for each property. Dierent engineers may make
dierent estimates of resources, cash ows, or other variables based on the same available data.
Forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond the
Company's control, which could cause actual results and events to dier materially from those that are disclosed in

Pulsar may be unsuccessful in drilling commercially productive wells; the uncertainty of resource estimation;
operational risks in conducting exploration, including that drill costs may be higher than estimates ; commodity
prices; health, safety and environmental factors; and other factors set forth above as well as risk factors included in
