Pulsar Helium Commences Drilling of Jetstream #5
Pulsar Helium Inc. has commenced drilling operations for its Jetstream #5 well at the Topaz project in Minnesota, targeting a depth of 5,000 feet, with drilling beginning on November 28, 2025. Previous wells at the Topaz project have shown promising results, including Jetstream #1 which yielded up to 8.1% helium-4 and 14.5 parts per billion helium-3, and Jetstream #2 which encountered up to 6.5% helium and a shut-in pressure of approximately 151 psi. Jetstream #3 recorded a bottom-hole pressure of around 960 psi, and Jetstream #4 reached a total depth of 3,000 feet, encountering pressurized gas at 1,897 feet with an estimated bottom-hole pressure of 887 psi. The company also reported that Jetstream #1 was flow-tested in August 2025, delivering a peak flow rate of approximately 1.3 million cubic feet per day with a sustained average of 8.1% helium.

PULSAR HELIUM COMMENCES DRILLING OF JETSTREAM #5
Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) ("Pulsar" or the "Company"), a primary helium project development company, is pleased to announce that the drill rig and all ancillary equipment have been relocated to the Jetstream #5 drill pad, located 1.8 miles (3 kilometers) northeast of Jetstream #1, at the Company's flagship Topaz project in Minnesota, USA. Jetstream #5 has a planned target depth of 5,000 feet (1,524 meters). The Company is pleased to confirm that rigging-up operations commenced on Thursday, November 27, 2025, and that the Jetstream #5 well was spudded on Friday, November 28, 2025.
Topaz drilling campaign highlights:
- Jetstream #1 (47.63468333 N / -91.70114444 W).
Helium-3 discovery: Concentrations of up to 14.5 parts per billion (ppb) were recorded in produced gas.
Completion: January 13, 2025
TD: 5,100 feet / 1,555 meters
| Gas Concentrations: 4He 8.1% | 3He 14.5 PPB | CO2 72.9% |
Natural Flow: Yes, 200,000 cubic feet per day average over 7-day test with 60 psi drawdown
Well pressure: Well-head pressure ~122 PSI
Formation Water: None present
- Jetstream #2 (47.63330694 N / -91.70267305 W).
High helium and pressure: High helium concentrations encountered of up to 6.5% in initial gas samples, alongside a strong initial shut-in pressure ~151 psi (10.4 bar), notably higher than Jetstream #1 indicating a highly charged reservoir with excellent pressure support.
Completion: February 3, 2025
TD: 5,638 feet / 1,718 meters
| Gas Concentrations: 4He 5.6% | CO2 79.8% |
Natural Flow: Yes, 21,000 cubic feet per day average over 1-day test with 60 psi drawdown
Well pressure: Well-head pressure ~151 PSI
Formation Water: None present
- Jetstream #3 (47.64228213 N/ -91.70159457 W).
Strong reservoir pressure: Multiple pressurized gas zones throughout the drilling campaign with a calculated bottom-hole pressure of approximately 960 psi. This strong pressure reading indicates a robust, naturally pressurized, highly charged reservoir at the well location.
Completion: November 7, 2025
TD: 3,507 feet / 1,069 metres
Gas Concentrations: Unknown. Awaiting testing.
Natural Flow: Yes, value to be determined.
Well pressure (not under compression): Bottom-hole pressure ~960 psi
Formation Water: None present
- Jetstream #4 (47.63693443 N/ -91.7008531 W).
TD reached and helium zone penetrated: The Company's latest appraisal well, was successfully drilled to a total depth of 3,000 feet (915 meters) on November 25, 2025, penetrating the entire interpreted helium-bearing interval. During drilling, pressurized gas with an estimated bottom-hole pressure of approximately 887 psi was encountered at a depth of 1,897 feet (578 meters).
Completion: November 26, 2025
TD: 3,000 feet / 915 meters
Sustained Gas Concentrations: Unknown. Awaiting testing.
Natural Flow: Yes, value to be determined.
Well pressure: bottom-hole pressure ~887 psi
Formation Water: None present
About the Topaz Project
The Topaz project is located in northern Minnesota, USA, where Pulsar is the first mover and holds exclusive leases. Drilling at the Jetstream #1 appraisal well reached a TD of 5,100 feet (1,555 meters) in January 2025, successfully penetrating the entire interpreted helium-bearing reservoir and beyond. Drilling of the Jetstream #2 appraisal well was completed on February 1, 2025, reaching a TD of 5,638 feet (1,718 meters). Jetstream #3 reached TD on November 7, 2025, and during drilling the calculated bottom-hole pressure was ~960 psi, with down-hole testing and gas sampling to soon occur now that Jetstream #4 has been completed. In August 2025, the Jetstream #1 well was successfully flow-tested using a wellhead compressor, delivering a peak gas flow rate of approximately 1.3 million cubic feet per day with a sustained flow average of 8.1% helium (as helium-4). Recent laboratory analyses have also confirmed the presence of helium-3 in measurable concentrations The ongoing multi-well drilling campaign will build on these results to expand Pulsar's understanding of the reservoir.
