Pulsar Helium (TSX.V: PLSR, FSE: Y3K, WKN: A3EP2C) has achieved further success in its ongoing Jetstream drilling programme, with the Jetstream #5 appraisal well encountering another high-pressure gas inflow at a depth of 871 metres. Current estimates put the well pressure at around 1,292 psi, the highest gas pressure measured at Topaz to date.
The Company commenced drilling at Jetstream #5 on 28 November 2025 and since then, Pulsar has encountered gas at depths of 255 metres and at 451 metres in the same well. The current discovery is the third significant hit within this one well, which is far from complete, as the overall target drilling depth is up to 1,524 metres.
At the Topaz project in northern Minnesota, Pulsar has previously discovered primary helium deposits with extremely high concentrations of helium-4 as well as rare helium-3 and CO2. Several wells drilled by Pulsar in the past suggest a laterally extensive, helium-rich gas reservoir beneath the surface.
These positive results are now being substantiated and expanded with the ongoing Jetstream drilling programme. The programme aims to map the extent, pressure regime and gas composition of the reservoir to provide information for resource estimation and further development planning.
Highest gas pressure ever recorded at Topaz
Even with more drilling to be done, Jetstream #5 can already be considered a success, with three gas discoveries, one beneath the other discovered. The third of which has the highest pressure ever recorded on the project at 1,292 psi, while the second gas discovery had a gas pressure of 662 psi.
It is still too early to conclusively evaluate these results, but the findings indicate a high-pressure gas system at a relatively shallow depth, confirming Pulsar’s exploration model.
Pulsar plans further drilling and extensive testing to evaluate the latest drilling successes
Jetstream #5 has been drilling again since 3 January, 2026. During the drilling work to date, gas influx has been observed, particularly during circulation breaks, indicating a sustained presence of gas within the formation.
Once the remaining approximately 600 metres of Jetstream #5 have been completed, the rig will be moved to a location approximately 2.2 kilometres southwest of where the Jetstream #1 exploration well was drilled. Jetstream #6 will then be sunk here.
In parallel with the ongoing drilling, preparations have begun for a multi-well flow test programme. It is scheduled to commence in early February 2026 and will include flow tests followed by pressure build-up tests to evaluate the Jetstream #3, #4 and #5 wells.
At Pulsar, it is estimated that these test series will take about six weeks per borehole. The company intends to announce the data determined during the tests as soon as they are available and have been subjected to an initial review. Invested investors therefore have every reason to look forward to the coming weeks and the results they will bring with keen attention.
