Pulsar Helium's Jetstream No. 5 well hits gas zones

Executive Summary

• Pulsar Helium Inc. reports a pressurized gas encounter at its Jetstream No. 5 appraisal well at the Topaz project in Minnesota, marking the fifth consecutive well in the program to intersect gas.
• Gas was encountered at shallow depths of approximately 837 feet (255 metres) and 1,481 feet (451 metres), with an initial bottom-hole pressure of approximately 662 psi and visible gas influx observed.
• Down-hole wireline logging was completed at Jetstream No. 3 and No. 4, with data sent for interpretation, while flow testing is scheduled for January 2026 to quantify production potential.

Key Details

• Jetstream No. 5 Encounters:
  • Pressurized gas zones intersected at depths of ~837 feet (255 m) and ~1,481 feet (451 m).
  • Initial bottom-hole pressure calculated at ~662 pounds per square inch (psi).
  • Visible gas influx observed bubbling through drilling fluids at surface, confirming active gas flow under pressure.
  • Well is being drilled using continuous HQ core drilling (63.5 mm core) to maximize geological sample recovery.
  • Drilling is proceeding on a 24-hour schedule toward a target total depth of 5,000 feet (1,524 metres).
• Program Success Rate:
  • All five Jetstream appraisal wells drilled to date have encountered pressurized gas (100% success rate).
  • Jetstream No. 5 is located ~1.8 miles (3 km) northeast of the discovery well (Jetstream No. 1), extending the project's appraisal footprint.
• Jetstream No. 3 and No. 4 Testing:
  • Down-hole wireline tests completed Nov. 6–7, 2025.
  • Logs conducted include formation microresistivity imaging, dipole sonic, resistivity, gamma, and neutron density.
  • Data is currently being sent for expert evaluation and interpretation.
  • Next phase includes flow testing, gas sample collection (including helium-3 analysis), and pressure buildup testing, expected in January 2026.
• Topaz Project Context:
  • Located in northern Minnesota; Pulsar holds exclusive leases.
  • Primary helium discovery containing helium-4, helium-3, and CO2, not associated with hydrocarbon production.
  • Previous wells (Jetstream No. 1 and No. 2) showed high helium concentrations (8.1% and 5.6% respectively) and confirmed the presence of helium-3.
  • Current appraisal program aims to map reservoir extent, pressure regime, and gas composition to inform resource estimation.

Notable Quotes

• "To encounter pressurized gas once again in Jetstream No. 5 is both validating and exciting for our team. With all five Jetstream wells confirming gas, we now have a consistent track record that underscores the pervasive nature of the helium reservoir at Topaz. In particular, seeing a gas influx at such a shallow depth in Jetstream No. 5 is highly encouraging; it suggests the gas column is extensive and the reservoir pressure is robust across the field." — Thomas Abraham-James, President and CEO
