Pulsar Helium Inc. (TSXV:PLSR) entered an agreement with Lunar Helium-3 Mining to evaluate proprietary technology for recovering and concentrating helium-3 from its Topaz Project in Minnesota. The multi-phase testing program aims to establish whether the rare isotope can be extracted from the site's natural gas deposits.

Helium-3 is an extremely scarce resource, with annual U.S. supply estimated at just 1 to 2 kilograms and market values cited near $18 million per kilogram. Third-party testing previously confirmed helium-3 concentrations between 11.2 and 11.9 parts per billion at Topaz, presenting a potential high-margin revenue stream alongside primary helium operations if feasibility is proven.

The second phase of the evaluation program sets a target of reaching at least 95% helium-3 purity. Positive laboratory results could allow the partnership to progress toward a funded pilot project and commercial deployment, though management emphasized that technical and execution risks remain high.

Shares of Pulsar Helium dropped 11.01% to 0.97 CAD following the market update.
