PULSAR HELIUM ANNOUNCES THE COMMENCEMENT OF WELL-TESTING AT THE TOPAZ HELIUM PROJECT IN MINNESOTA

Pulsar Helium Inc. has commenced well-testing activities at Jetstream No. 1 and Jetstream No. 2 at its flagship Topaz project in Lake county, Minnesota.

Well-testing activities are expected to occur in two sequential phases; the initial phase will focus on flow testing at the Jetstream No. 1 and Jetstream No. 2 appraisal wells, followed by a second phase of extended pressure buildup monitoring.

The initial phase of flow testing began on April 1, 2025, and is expected to continue over approximately four weeks.

The second phase will consist of extended pressure buildup monitoring through the end of June, 2025.

The well-testing program data are needed to prepare a resource update.

Thomas Abraham-James, president and chief executive officer of Pulsar, commented: "The commencement of well-testing activities at the Jetstream No. 1 and No. 2 wells at our Topaz helium project in Minnesota is a significant milestone. Flow, pressure and gas sample data will be collected and will build upon the drilling success achieved at Topaz to date. We look forward to keeping the market updated with progress."

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 CO2 (carbon dioxide) concentrations exceeding 70 per cent -- with the latter expected to further contribute to the project economics. 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.
