Pulsar Helium Inc (LSE:PLSR) shares surged in Monday's trade, after the small-cap reported major flow test results from the Jetstream-1 appraisal well at its Topaz project in Minnesota.
The well saw a peak natural flow rate of about 501 thousand cubic feet pay during tests, it said.
"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.
“The well is now naturally flowing at ~501 thousand cubic feet per day at 30 pounds per square inch WHP, more than three times the peak natural flow achieved in 2024."
Pulsar shares were up just over 20% at 30.78p.
