Pulsar Helium Inc (PLSR) has successfully finished drilling the Jetstream #2 appraisal well at its flagship Topaz project in Minnesota, USA.
On February 1, 2025, the drilling operation reached a total depth of 5,638 feet, fully penetrating the interpreted helium-bearing interval and extending beyond it.
Elevated helium values were recorded over a gross vertical thickness of 3,178 feet, with samples showing up to 3.5% helium—although this figure may be diluted due to the rotary air drilling method used. The true helium concentration is expected to be higher, and uncontaminated samples will be collected for laboratory analysis.
The next phase involves collecting additional data, which will be submitted to an independent resource estimator for an updated resource assessment and to Chart Industries to evaluate production scenarios and design a conceptual processing facility.
Key Achievements
• Successful Drilling: Jetstream #2 reached its target depth of 5,638 feet on February 1st, 2025.
• Promising Helium Readings: Mud log gas levels containing up to 3.5% helium were encountered during drilling. These samples are diluted by atmospheric air due to the rotary air drilling method used, where air is forced into the well by compressors. Actual helium concentration is likely higher than the measured 3.5% and uncontaminated samples for laboratory analysis will be acquired in due course to determine the true helium concentration.
• Expanded Reservoir: Elevated helium values were encountered in Jetstream #2 over a gross vertical thickness of 3,178 feet (969 metres), commencing at 2,460 feet (650 metres) to and ending at TD.
• Comprehensive Data Collection: Down-hole wireline logging data was acquired on February 1st, this data will be integrated with additional downhole data that will be acquired over the coming weeks.
• Next Steps: Additional data collection, including optical televiewer, high-definition spectroscopy, pressure, and flow testing, will be conducted for Jetstream #1 and #2 in February and March. All data will then be sent to an independent resource estimator for a resource update, and to Chart Industries for production scenario assessment and conceptual processing facility design.
Thomas Abraham-James, President & CEO of Pulsar Helium, commented on the drilling:
“Drilling of the Jetstream #2 appraisal well and deepening of Jetstream #1 is now complete, both of which were a resounding success with multiple high-concentration helium shows encountered. My congratulations to our operational team for accomplishing these tasks on time and without injury. The newly identified gas shows and highly encouraging helium readings give us great confidence for this being the most significant new primary helium discovery in North America. We now move into the all-important testing phase and I look forward to keeping the market updated with results as they arrive.”
