PULSAR HELIUM ANNOUNCES UPDATE FOR JETSTREAM WELL TESTING PROGRAM AT TOPAZ, MINNESOTA

The well cleanup and flow-testing program for the Jetstream No. 1 and No. 2 wells at Pulsar Helium Inc. 's Topaz project in Minnesota is to commence in mid-July and is scheduled to be completed in early August. Drawing on research from geologically comparable settings, the company has tailored its well cleanup procedure to ensure optimal results. The company is financed for this work program and the data will provide significant insights to the Topaz project's production potential.

The well-testing program

The first phase of testing both Jetstream wells will commence with a cleanup, whereby drill fines (rock dust) that are currently present in fractures and partially coating the wellbore will be removed (refer to Pulsar's news release April 28, 2025).

The cleanup operation will be carried out using coil tubing deployed into the wells from a truck-mounted unit, eliminating the need for a drill rig, and will involve treating the wells with a combination of water, nitrogen and NSF 60-compliant additives.

Following the completion of well cleanup, the next phase will consist of pressure and flow-testing operations at both the Jetstream No. 1 and No. 2 wells, with samples collected for laboratory testing. Results will be released to the market throughout the well-testing program as they become available and have been verified.

Note: NSF 60 refers to the NSF/ANSI/CAN 60 standard, which is an American national standard that sets the minimum health effects requirements for chemicals used in the treatment of drinking water. This standard ensures that any chemicals, chemical contaminants and impurities directly added to drinking water during treatment do not pose unacceptable health risks to consumers.

Thomas Abraham-James, president and chief executive officer of Pulsar, commented: "I am happy to announce that well testing of Jetstream No. 1 and No. 2 will soon be under way. Following the encouraging pressure readings recorded during our Q1 drilling program, we're eager to recommence flow testing once both wells have been cleared of blockages. The program is fully financed and will give us the data we need to advance the Topaz primary helium project, creating the next phase of exciting news flow for our stakeholders."

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 has now 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. Drilling of the Jetstream No. 2 appraisal well was completed on Feb. 1, 2025, reaching a TD of 5,638 feet (1,718 metres). The deepening of Jetstream No. 1 and completion of the drilling of Jetstream No. 2 are pivotal steps in advancing Pulsar's strategy to address the increasing global demand for helium as the company moves another step closer to production.
