Pulsar Helium Advances Minnesota Operations with High Pressure Gas Discovery at Jetstream 5

Pulsar Helium Inc has reported a significant development at its Topaz Project in Minnesota, with shares rising 7% to 57 pence in early Friday trading following the announcement of a high-pressure gas encounter at the Jetstream 5 appraisal well.

The London-listed helium exploration company disclosed that the new gas zone was intersected at approximately 2,857 feet depth. The bottom-hole pressure at this newly identified zone was estimated at approximately 1,292 pounds per square inch, representing the highest pressure recorded at the project to date. This discovery follows previously reported gas zones encountered at shallower depths within the same well.

Drilling operations at Jetstream 5 continue towards a planned total depth of up to 5,000 feet. Upon completion of this phase, the drilling rig is scheduled to relocate to Jetstream 6, positioned approximately 2.2 kilometres southwest of the original discovery well.

The company has outlined plans for a combined flow testing and pressure build-up programme commencing in early February 2026. This campaign is expected to span approximately six weeks per well and will encompass Jetstream wells 3, 4 and 5. Management has committed to sharing interim results with the market following data collection and verification.

The elevated pressure readings at Jetstream 5 represent a potentially positive indicator for the commercial viability of the helium resource. Higher pressures typically suggest improved flow rates and production economics, though comprehensive testing will be required to confirm these expectations.

The sequential drilling and testing approach being employed by Pulsar Helium appears designed to systematically assess the extent and characteristics of the helium reservoir across multiple well locations. The February testing programme will be particularly significant in determining flow rates and sustainable production capacity from the identified zones.

For investors monitoring the helium sector, the Topaz Project developments warrant attention given the ongoing global supply dynamics for this critical industrial gas. The forthcoming flow testing results should provide more definitive data regarding the commercial potential of this Minnesota asset.
