PULSAR HELIUM REPORTS COMMENCEMENT OF JETSTREAM #7 AND COMPLETION OF SEISMIC SURVEY AT THE TOPAZ HELIUM PROJECT, USA
Pulsar Helium Inc. (AIM: PLSR, OTCQB: PSRHF, TSXV: PLSR), a primary helium company, is pleased to announce that drilling of Jetstream #6 at the Company’s flagship Topaz Project in Minnesota, USA has been completed at a total depth (TD) of 2,597 feet. The drill rig has now mobilized to Jetstream #7 where surface casing has been set and cemented and drilling is underway. In addition, the extensive 2D active seismic acquisition program at its Topaz Project has been completed, with a total of five seismic lines spanning 41.5 miles having been successfully acquired.
Highlights:
• Jetstream #6 Completed: Successfully drilled to a total depth of 2,597 feet, encountering multiple pressurized gas intervals and further supporting the Topaz geological model.
· Previously reported gas zones at 1,287 ft (~576 psi), 2,120 ft (~981 psi), 2,187 ft (~1,012 psi) and 2,377 ft (~1,100 psi), with gas observed at surface during drilling.
• Jetstream #7 Underway: Drilling has commenced following rig mobilization, targeting a planned TD of 3,000 feet, with potential to deepen to 5,000 feet; located 2.2 miles northwest of Jetstream #1 as a significant step-out appraisal well.
• 2D Seismic Program Completed: Five seismic lines totaling 41.5 miles successfully acquired across the Topaz Project on February 20, 2026.
• Independent QA/QC Reviewed: Raw seismic data reviewed onsite by an independent expert contractor and validated as good quality.
• Processing & Interpretation Initiated: Dataset being transferred to Earth Signal (Calgary) for processing, with the interpretation to be conducted in-house and the data used to refine structural mapping, support resource assessment, and optimize future drilling.

Jetstream #6 Summary
Jetstream #6 has now been successfully drilled to a total depth of 2,597 feet and is complete, marking another important milestone in the ongoing appraisal of the Topaz Helium Project in Minnesota. During drilling, multiple pressurized gas intervals were encountered, including zones previously reported at 1,287 feet (~576 psi), 2,120 feet (~981 psi), 2,187 feet (~1,012 psi) and 2,377 feet (~1,100 psi), with gas observed bubbling to surface through drilling fluids, confirming the presence of pressurized gas within the intersected formations. The well was drilled using continuous HQ core to maximize geological data recovery and further supports the Company’s geological model across the Topaz structure.
Jetstream #7
Drilling of the Jetstream #7 appraisal well commenced February 19, with a planned TD of 3,000 feet and the potential to deepen to 5,000 feet. At the time of writing this announcement, the surface casing has been set and cemented and the hole is at a depth of 737 feet. Jetstream #7 is located 2.2 miles to the northwest of Jetstream #1, another considerable step out with the intention of increasing the size of the Topaz resource.
Successful Completion of 2D Seismic Survey
Pulsar has successfully completed its extensive 2D active seismic acquisition program at the Topaz Helium Project in Minnesota on February 20, 2026. The survey, designed to comprise five lines totaling approximately 41.5 miles, was undertaken to further elucidate the subsurface structure of the Topaz reservoir and support ongoing resource assessment and future drilling target definition. The program utilized low-impact seismic techniques, deploying Vibroseis energy sources and wireless geophone nodes to generate high-resolution cross-sectional images of the subsurface beneath each survey line.
The raw seismic data has been QA/QC reviewed onsite by an independent expert contractor and confirmed to be of good quality. The dataset is now being transferred to Earth Signal in Calgary for processing and the interpretation will be conducted in-house. 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 drilling.
About the Topaz Project
The Topaz Helium Project is a large-scale 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 six appraisal wells have been drilled at Topaz (the seventh is now underway), all of which intersected pressurized gas, representing a 100% success rate to date and supporting the geological model for the project. Ongoing technical work continues to generate encouraging data and is focused on expanding the Company’s understanding of the resource through further appraisal, testing and analysis. With a significant acreage position and multiple identified targets, Topaz represents a core asset within the Company’s portfolio and underpins its strategy to build exposure to high-value industrial and specialty gas markets.
