Mr. Thomas Abraham-James reports PULSAR HELIUM APPOINTS CLIFF CAIN AS MANAGER OF COMMERCIAL AND EXTERNAL AFFAIRS AND ANNOUNCES COMPLETION OF JETSTREAM #4 WITH INCREASED BOTTOM-HOLE PRESSURE Pulsar Helium Inc. has appointed Cliff Cain, a veteran industrial gas executive and renowned helium market strategist, as manager of commercial and external affairs. In addition, at the company's flagship Topaz helium project in Minnesota, United States, Jetstream No. 4 has reached total depth (TD) and the drill rig is now preparing to relocate to the Jetstream No. 5 pad. Highlights: Manager of commercial and external affairs appointment: Mr. Cain has been appointed as a full-time member of the company and has relocated to Duluth, Minn. Drilling completed: Jetstream No. 4 reached a TD of 3,000 feet (914 metres) on Nov. 25, successfully penetrating the full interpreted helium-bearing interval. Increased bottom-hole pressure: During drilling, pressurized gas with an estimated bottom-hole pressure of approximately 887 pounds per square inch was encountered at a depth of 1,897 feet (578 metres) (subject to change when final bottom-hole and wellhead pressures are obtained during evaluation). Jetstream No. 5: With drilling at Jetstream No. 4 now complete, the drill rig is now being relocated to Jetstream No. 5, located 1.8 miles (2.9 kilometres) northeast of Jetstream No. 1, with a target depth of 5,000 feet (1,524 metres). Next steps, testing and analysis: With drilling complete at Jetstream No. 4, a comprehensive downhole evaluation program will start across both Jetstream No. 3 and No. 4. The decision was made to test both wells simultaneously to reduce mobilization costs and therefore achieve a more efficient deployment of capital. The program will include open-hole wireline logs, flow testing and pressure buildup analysis. At the same time, core and gas samples from Jetstream No. 3 and No. 4 will be analyzed to determine gas composition and helium content. Thomas Abraham-James, president and chief executive officer of Pulsar, commented: "Cliff's decision to join Pulsar full-time is a strong vote of confidence in our mission and direction. He is one of the most respected strategists in the industrial gas industry, and his decades of experience and market insight will be invaluable as we advance Topaz toward final investment decision. With Cliff leading our commercial and external affairs, we are significantly strengthening our ability to forge strategic partnerships and turn our discovery into a successful, revenue-generating operation. "In addition, it is my pleasure to, once again, report the successful completion of drilling at a further well, Jetstream No. 4, at our flagship project, Topaz, in Minnesota, USA. Having now reached total depth, the results are promising and reinforce our belief in our helium discovery. With downhole evaluation now starting on Jetstream No. 3 and No. 4 and with the drill rig being mobilized to Jetstream No. 5, momentum continues as we head towards the end of 2025 and advance our drilling campaign."

Jetstream No. 4 well update While bolstering its leadership team, Pulsar is concurrently advancing the drilling program at its flagship Topaz helium project in Minnesota. Jetstream No. 4, the company's latest appraisal well, was successfully drilled to a total depth of 3,000 feet (914 metres) on Nov. 25, 2025, penetrating the entire interpreted helium-bearing interval. During drilling, pressurized gas with an estimated bottom-hole pressure of approximately 887 pounds per square inch was encountered at a depth of 1,897 feet (578 metres) (subject to change when final bottom-hole and wellhead pressures are obtained during evaluation). This is an increase from the previously reported (see Pulsar's news release dated Nov. 18, 2025) approximately 674 pounds per square inch at a depth of 1,457 feet (444 metres). With Jetstream No. 4 now complete, the drill rig is being mobilized to the Jetstream No. 5 location, which has a target depth of 5,000 feet (1,524 metres) and is approximately 1.8 miles (2.9 kilometres) northeast of Jetstream No. 1. Drilling at Jetstream No. 5 is expected to commence by Nov. 29, 2025. This continued pace reflects Pulsar's commitment to an aggressive multiwell campaign (up to 10 wells in total) designed to delineate the geometry, extent and productivity of the Topaz reservoir. Well testing Pulsar will now initiate a comprehensive downhole evaluation program on both Jetstream No. 3 and No. 4 in parallel. By conducting the testing on both wells simultaneously, the company aims to reduce mobilization costs and accelerate data collection. The evaluation will include open-hole wireline logging, flow testing and pressure buildup analysis, alongside laboratory analysis of core and gas samples to determine gas composition and helium content. Notably, the lab work will test for the presence of helium-3 isotope, previously detected at notable levels in the Topaz field, to see if Jetstream No. 3 and No. 4 exhibit a similar helium-3 signature. Additional corporate developments Broker update The company announces that, effective immediately, Strand Hanson Ltd. is now acting as the sole broker to the company. Marketing engagement The company notes that it has engaged United Kingdom-based ShareTalk Ltd. as a consultant to support its investor communications and will pay ShareTalk 3,000 British pounds for a six-month term commencing on Dec. 1, 2025. ShareTalk will provide services including audio podcasts, video interviews, articles, company updates and management interviews as well as communicate with investment dealers, advisers, and both current and prospective shareholders to increase awareness of and interest in Pulsar. The company's agreement with ShareTalk has no stipulated notice period and can be terminated by either party with immediate effect. ShareTalk has advised the company that it does not currently hold any common shares in the company; as such, ShareTalk and the company are unrelated and unaffiliated entities. 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, 2025, and, during drilling, the calculated bottom-hole pressure was approximately 960 pounds per square inch, with downhole testing and gas sampling to soon occur now that Jetstream No. 4 has been completed. 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. About Pulsar Helium Inc.
