Pulsar Helium triples Jetstream No. 1 flow at Topaz

Mr. Thomas Abraham-James reports PULSAR HELIUM ANNOUNCES MAJOR FLOW TEST RESULTS AT JETSTREAM #1, TOPAZ PROJECT Pulsar Helium Inc. has released major natural flow test results at the Jetstream No. 1 appraisal well, part of the Topaz helium project in Minnesota, United States. These latest results mark a major leap in well performance, with natural flow rates more than tripling those recorded in 2024. A summary of the results is as follows: On Aug. 15, 2025, Jetstream No. 1 achieved a peak natural flow rate of approximately 501,000 cubic feet per day (approximately 501 Mcf/d (thousand cubic feet per day)) on a 38/64-inch choke at approximately 30 pounds per square inch (psi) well head pressure (WHP), achieved with no compression or stimulation. No formation water has been encountered; the gas has flowed as dry gas. Substantial improvement over 2024 tests: In April, 2024, Jetstream No. 1 achieved a peak natural flow of approximately 150 Mcf/d at 34 psi WHP (approximately 821 Mcf/d under well-head compression) with helium concentrations ranging from 8.7 per cent to 14.5 per cent; the well is now flowing at more than three times the rate recorded in April, 2024, under similar pressure conditions. Significance and next steps: As Pulsar president and chief executive officer Thomas Abraham-James stated in April, 2024, the Jetstream No. 1 results confirmed a "major new helium discovery, putting Topaz in the top tier of global primary helium projects." The latest test program builds decisively on that foundation, validating Topaz's potential as a globally significant source of primary helium. Further updates imminent: Additional sustained-flow results, flow results under well-head compression and full gas composition analyses are in the process of being obtained. When testing is complete, all equipment will then be moved to Jetstream No. 2 for equivalent testing. Thomas Abraham-James, president and CEO of Pulsar, commented: "The deepening of the Jetstream No. 1 appraisal well to a total depth of 5,100 feet, penetrating the entire interpreted helium-bearing zone, has proven highly successful. The well is now naturally flowing at approximately 501,000 cubic feet per day at 30 pounds per square inch WHP, more than three times the peak natural flow achieved in 2024. This result validates our subsurface model, significantly derisks the Topaz project and confirms the reservoir's outstanding productivity. This is especially exciting considering the 2024 gas analysis for the same well returned helium concentrations ranging from 8.7 per cent to 14.5 per cent. With further flow testing, including under well-head compression and gas composition analyses to follow, we look forward to sharing further updates and the results of Jetstream No. 2. These results underscore the immense opportunity at Topaz and signal the start of unlocking its full potential." Test results and analysis The Jetstream No. 1 well delivered a maximum natural flow rate of approximately 501,000 cubic feet per day (Mcf/d) during open-flow testing on Aug. 15, 2025. This was observed on a 38/64-inch choke at approximately 30 psi WHP, without compression assistance. By comparison, during initial appraisal in April, 2024, Jetstream No. 1 reached a peak natural flow of approximately 150 Mcf/d at 34 psi. The improvement of more than threefold under near-identical pressure conditions highlights the effectiveness of recent wellbore clean-up and deepening and underscores the formation's strong productivity. Importantly, no formation water has been encountered, the gas has flowed as dry gas. In addition to the peak result, Jetstream No. 1 demonstrated stable long-duration flows, producing 150 to 300 Mcf/d for periods of 12 to 18 hours on smaller choke sizes. These sustained flows showed no significant decline and were followed by rapid pressure recovery, indicating excellent reservoir recharge capacity. Compression testing and expected upside To further assess the well's maximum capacity, Pulsar is commencing a compression-assisted flow test. By reducing WHP via surface compression, flow rates are expected to increase significantly. For reference, compression applied during the February, 2024, test program resulted in a maximum flow rate of approximately 821 Mcf/d. The current test is designed to validate Jetstream No. 1's full potential and provide key data for production facility design and future development planning. A brief explanation of flow testing under "natural" conditions and under "compression" When a well produces under natural flow, the gas comes to surface on its own, pushed out purely by the pressure in the reservoir. It is a strong indicator of how much energy the reservoir holds. With compression, special surface equipment is used to lower the pressure at the wellhead, which makes it easier for the gas to flow out. This does not change the size of the reservoir, but it allows much higher flow rates and gives a clearer picture of the well's maximum production potential. 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 total depth (TD) of 5,100 feet (1,555 metres) on Jan. 11, 2025, successfully penetrating the entire interpreted helium-bearing reservoir and beyond. The Jetstream No. 1 appraisal well previously reached TD of 2,200 feet (671 metres) on Feb. 27, 2024, identifying top-tier helium concentrations of up to 14.5 per cent, well above the 0.3 per cent widely accepted economic threshold and flowed at a rate of 821,000 cubic feet per day under well-head compression. Drilling of the Jetstream No. 2 appraisal well was completed on Feb. 1, 2025, reaching a TD of 5,638 feet (1,718 metres). These activities will progress Pulsar's strategy become a producer of helium, addressing increasing global demand. About Pulsar Helium Inc.
