Pulsar drills Jetstream No. 6 to 2,597 feet depth

Mr. Thomas Abraham-James reports PULSAR HELIUM REPORTS COMMENCEMENT OF JETSTREAM #7 AND COMPLETION OF SEISMIC SURVEY AT THE TOPAZ HELIUM PROJECT, USA Drilling of Jetstream No. 6 at Pulsar Helium Inc.'s flagship Topaz project in Minnesota, United States, has been completed at a total depth of 2,597 feet. The drill rig has now mobilized to Jetstream No. 7, where surface casing has been set and cemented and drilling is under way. In addition, the extensive 2-D 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 No. 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 feet (approximately 576 pounds per square inch), 2,120 feet (approximately 981 psi), 2,187 feet (approximately 1,012 psi) and 2,377 feet (approximately 1,100 psi), with gas observed at surface during drilling; Jetstream No. 7 under way: drilling has commenced following rig mobilization, targeting a planned total depth of 3,000 feet, with potential to deepen to 5,000 feet, located 2.2 miles northwest of Jetstream No. 1 as a significant stepout appraisal well; 2-D seismic program completed: five seismic lines totalling 41.5 miles successfully acquired across the Topaz project on Feb. 20, 2026; Independent quality assurance/quality control reviewed: raw seismic data reviewed on site by an independent expert contractor and validated as good quality; Processing and interpretation initiated: data set 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 No. 6 summary Jetstream No. 6 has now been successfully drilled to a total depth of 2,597 feet and is complete, marking another important milestone in the continuing appraisal of the Topaz helium project in Minnesota. During drilling, multiple pressurized gas intervals were encountered, including zones previously reported at 1,287 feet (approximately 576 psi), 2,120 feet (approximately 981 psi), 2,187 feet (approximately 1,012 psi) and 2,377 feet (approximately 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 No. 7 Drilling of the Jetstream No. 7 appraisal well commenced Feb. 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 No. 7 is located 2.2 miles to the northwest of Jetstream No. 1, another considerable stepout with the intention of increasing the size of the Topaz resource. Successful completion of 2-D seismic survey Pulsar has successfully completed its extensive 2-D active seismic acquisition program at the Topaz helium project in Minnesota on Feb. 20, 2026. The survey, designed to comprise five lines totalling approximately 41.5 miles, was undertaken to further elucidate the subsurface structure of the Topaz reservoir and support continuing 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 have been quality assurance/quality control reviewed on site by an independent expert contractor and confirmed to be of good quality. The data set 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, United States, 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 under way), all of which intersected pressurized gas, representing a 100-per-cent success rate to date and supporting the geological model for the project. Continuing 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.
