Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) Completion of Jetstream 7, Start Down-Hole Logging
PULSAR HELIUM REPORTS COMPLETION OF JETSTREAM #7 AND COMMENCEMENT OF DOWN-HOLE LOGGING AT THE TOPAZ HELIUM PROJECT, USA
Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF), a primary helium company, is pleased to announce the successful completion of drilling at the Jetstream #7 appraisal well at the Company’s flagship Topaz Helium Project in Minnesota, USA, having reached a total depth (TD) of 2,979 feet (908 meters) on March 10, 2026. As previously reported (news release March 4, 2026), gas was encountered during drilling at approximately 2,107 feet (642 meters) with a preliminary bottom-hole pressure of approximately 953 pounds per square inch (psi), with visible gas influx confirming a strongly pressurized system. Down-hole logging of Jetstream #7 was completed on March 17, 2026, with the logging truck now mobilizing to Jetstream #6. The drill rig has mobilized to Jetstream #5 to facilitate the recovery of the drill string that is in the hole, following which this campaign of exploratory drilling will successfully conclude. Flow and pressure build-up testing of the Jetstream wells is anticipated to commence in late March or early April 2026. The Jetstream wells continue to maintain a 100% success rate of intersecting pressurized gas.
Highlights:
• Jetstream #7 drilling completed: Drilling of Jetstream #7 reached a total depth of 2,979 feet (908 meters) on March 10, 2026, successfully concluding the well.
• Previously reported gas encounter: As reported in the Company’s news release of March 4, 2026, gas was encountered at approximately 2,107 feet (642 meters) with a preliminary bottom-hole pressure of approximately 953 psi. Visible gas influx was observed during drilling operations, confirming a strongly pressurized system.
• 100% success rate maintained: All seven Jetstream appraisal wells drilled at Topaz to date have encountered pressurized gas, underscoring the continuity and strength of the Topaz helium system.
• Down-hole logging of Jetstream #7 complete: Down-hole logging was completed by Extreme Wireline on March 17, 2026, collecting a full suite of logs, including Compact Microimager (CMI). The wireline logging truck has now mobilized to Jetstream #6, where logging operations are expected to commence shortly.
• Jetstream #5, final preparation for logging and flow testing: The drill rig is mobilized to Jetstream #5 to complete standard engineering operations to retrieve or bypass drill string remaining in the well, after which the rig will demobilize and the well will be fully prepared for logging and flow testing alongside the wider Jetstream program.
• Flow and pressure build-up testing: Flow and pressure build-up testing across the Jetstream wells is anticipated to commence in late March or early April 2026. Timing reflects standard well preparation and clean-out operations required prior to testing to ensure acquisition of accurate and representative data.
• Seismic data processing complete: Processing of the 2D active seismic data acquired in February 2026 has been completed by Earth Signal (Calgary). The dataset has been confirmed to be of good quality and will now be interpreted by Chief Geologist Professor Nick Schofield, with results expected to enhance the Company’s structural understanding of the Topaz system and inform future appraisal targeting.
Thomas Abraham-James, President & CEO of Pulsar, commented:
“The successful completion of Jetstream #7 marks the end of an intensive and highly productive exploratory drilling campaign at Topaz, one that has delivered a perfect seven-from-seven success rate. Gas has been encountered in every single well drilled, a remarkable outcome that continues to validate the strength of our geological model. With down-hole logging now underway across the field and flow testing set to commence imminently, we are on the cusp of defining the scale and commercial potential of the Topaz resource. At a time when the strategic importance of new primary helium supply from stable jurisdictions has never been clearer, we look forward to updating the market as results from the testing program are received and verified.”
Summary of Jetstream #7
Drilling of the Jetstream #7 appraisal well reached a total depth of 2,979 feet (908 meters) on March 10, 2026. As reported in the Company’s news release of March 4, 2026, the well intersected a pressurized gas zone at approximately 2,107 feet (642 meters), with a preliminary bottom-hole pressure of approximately 953 psi and visible gas influx observed at surface, confirming a strongly pressurized system.
Down-Hole Logging
Down-hole logging of Jetstream #7 was completed on March 17, 2026, by Extreme Wireline INC. The down-hole logging suite employed a full set of logging tools, including Compact Microimager (CMI), providing detailed petrophysical and geological data across the full drilled interval to characterize the gas-bearing formations encountered during drilling. The wireline logging truck has now mobilized to Jetstream #6, where logging operations are expected to commence shortly.
Jetstream #5, Drill String Recovery
The drill rig is mobilized to Jetstream #5, where, as previously reported (news release January 28, 2026), 1,239 feet of drill string remains in the well following operations at TD. The rig will undertake operations to retrieve or bypass the drill string, enabling the logging of the 3,839-foot (1,170-meter) well. Upon successful completion of this work, the drill rig will leave site, and this campaign of exploratory drilling at the Topaz Helium Project will successfully conclude.
Flow Testing and Pressure Build-Up Program
Pulsar anticipates commencing a coordinated flow and pressure build-up testing program across the Jetstream wells in late March or early April 2026. Timing reflects standard well preparation and clean-out operations required prior to testing to ensure acquisition of accurate and representative data. The program is expected to consist of an initial flow testing phase followed by a period of pressure build-up. Interim results will be released to the market as data is received and verified by the Company.
Seismic Data Processing
Processing of the 2D active seismic data acquired across the Topaz Project in February 2026 has been completed by Earth Signal in Calgary. The processed dataset has been confirmed to be of good quality. Interpretation of the seismic data will now be undertaken by Chief Geologist Professor Nick Schofield. The results are expected to enhance the Company’s structural understanding of the Topaz system, refine reservoir mapping, and assist in optimizing future appraisal and development activities.
About the Topaz Project
The Topaz Helium Project is a helium exploration opportunity located in Minnesota, USA, a stable jurisdiction with established infrastructure and access to experienced technical services. Exploration and appraisal work to date has identified potentially saleable concentrations of helium, helium-3 and carbon dioxide. Helium-3 is a rare isotope of helium with strategic applications in national security, quantum computing and advanced energy technologies, providing additional potential upside. A total of seven appraisal wells have been drilled at Topaz, all of which intersected pressurized gas, representing a 100% success rate to date and supporting the geological model for the project. With seven appraisal wells drilled and a 100% success rate, the Topaz Project now moves into a pivotal flow testing phase that is expected to define the scale and commercial potential of the helium resource, underpinning the Company’s strategy to become a leading supplier of primary helium to high-value industrial and specialty gas markets.
