08:37 AM EDT, 08/18/2025 (MT Newswires) -- Pulsar Helium ( PSRHF ) traded 20% higher at last look Monday in U.K. trading as the company reported the improved performance of the Jetstream #1 appraisal well within the Topaz helium project in Minnesota.

The well achieved a peak natural flow rate of 501,000 cubic feet per day on Aug. 15, more than triple of the peak natural flow rate of 150,000 cubic feet per day recorded in April 2024.

"The deepening of the Jetstream #1 appraisal well to a total depth of 5,100 feet, penetrating the entire interpreted helium-bearing zone, has proven highly successful," said Thomas Abraham-James, president and CEO of Pulsar. "This result validates our subsurface model, significantly de-risks the Topaz project, and confirms the reservoir's outstanding productivity."

When testing is complete, Pulsar said it will move all equipment to Jetstream #2 for equivalent testing.

"These results underscore the immense opportunity at Topaz and signal the start of unlocking its full potential," Abraham-James said.
