With helium concentrations of up to 8% confirmed in recent well tests, Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) has set a new benchmark and demonstrated the exceptional potential of its Topaz Project in Minnesota. These unusually high grades exceed the typical commercial threshold of around 0.3% many times over and firmly establish Topaz as one of the most significant new primary helium discoveries in North America.
Jetstream #1 delivers outstanding results
At the Jetstream #1 appraisal well, which was deepened to 5,100 feet in 2025, laboratory analysis confirmed sustained helium concentrations of 7–8% over extended flow periods. During open flow testing, the well achieved natural flow rates of up to 501 thousand cubic feet per day (Mcf/d) without compression. Under surface compression, peak rates climbed to an impressive 1.3 million cubic feet per day (MMcf/d). Remarkably, the gas flowed dry – containing only helium, CO₂, and trace gases, but no hydrocarbons or formation water – which should significantly simplify future processing.
CO₂ as a Second Pillar for Pulsar
The gas composition consists of approximately 75 to 80 percent CO₂. What appears unusual at first glance opens up additional economic opportunities. The carbon dioxide could be utilized and marketed as a byproduct, further increasing the project’s profitability. Methane, which often presents technical challenges, is only present in trace amounts.
Jetstream #2 Demonstrates Strong Pressure Potential
The second appraisal well, Jetstream #2, also showed helium content of up to 8 percent in samples. Particularly noteworthy is the significantly higher pressure compared to Jetstream #1: With approximately 151 psi (10.4 bar), a highly charged reservoir is confirmed. Although continuous gas flow was impaired by wellbore blockages, Pulsar is already planning a targeted cleanout program to unlock the full potential.
Pulsar CEO Thomas Abraham-James commented: “The consistency of high helium grades across both wells confirms the exceptional potential of Topaz. With the planned wellbore cleanout at Jetstream #2 and upcoming core drilling, we are in an excellent position to develop Topaz into a leading new helium project in North America.”
With helium concentrations of up to 8%, excellent flow performance at Jetstream #1, and strong reservoir indicators at Jetstream #2, Pulsar Helium has laid the groundwork for what could become one of the most prominent new primary helium projects in the Western Hemisphere. The unusually high helium grades, combined with favorable CO₂ byproduct potential and minimal impurities, provide a compelling case for development – and highlight the potential opportunity for investors.
