CASCAIS, Portugal, April 28, 2025 (GLOBE NEWSWIRE) --

Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) (“Pulsar” or the “Company”), a primary helium development company, announces an update for well-testing activities at Jetstream #1 and Jetstream #2 at its flagship Topaz project in Lake County, Minnesota.

Pressure and flow testing operations were conducted on the Jetstream #1 and #2 appraisal wells with well-head pressure at both being highly encouraging, reaching 122 PSIG* at Jetstream #1 and 151 PSIG at Jetstream #2. Well-head pressure at Jetstream #2 is greater than Jetstream #1 was in February 2024 (145 PSIG) when it achieved a flow rate of 821,000 cubic feet per day, under well-head compression.

During flow testing activities, it was discovered that drilling fines (rock dust) created by the air drilling method (that pulverizes the rock) were present within fractures and partially coating the wellbore wall. The creation of drilling fines is commonplace when air drilling Although gas flow may be restricted, pressure communication still occurs (albeit also constrained) which is why the Company was unaware of the restricted flow until testing commenced.

The Company has performed a preliminary clean-up on both wells to mobilise the drilling fines, achieving improved flow results, demonstrating that the drilling fines are mobile and can be removed. Despite the currently restricted conditions, stable and consistent flow rates were achieved under with both wells flowing natural flow and on compression.

Further flow testing of the Jetstream wells will recommence when clean-up of the wells is complete and the drilling fines have been removed, all of which are anticipated to be completed in the next 6 - 10 weeks.

Thomas Abraham-James, President & CEO of Pulsar, commented:

We are pleased with these preliminary findings and look forward to being able to resume flow testing when the rock dust has been removed from the wells. Our technical team is taking the necessary measures to complete the clean-up and we will advise investors as soon as these works are complete and when testing will be resumed.”
