08:06 AM EST, 01/06/2025 (MT Newswires) -- Pulsar Helium ( PSRHF ) on Monday said drilling to deepen the Jetstream #1 appraisal well at its Topaz project in Minnesota began last week.

Pulsar plans to deepen the appraisal well by at least 1,640 feet, to a total depth of no less than 3,840 feet. This is expected to be completed later this week. When complete, downhole tools will be used to gather data on the well characteristics.

The Jetstream #1 appraisal well reached total depth of 2,200 feet early last year, identifying top-tier helium concentrations of up to 14.5%, well above the 0.3% widely accepted economic threshold, Pulsar said.
