U.S. Federal Labs Confirm High-Grade Helium-3 Discovery at Pulsar’s Topaz Project

An update from Pulsar Helium, Inc. ( (TSE:PLSR) ) is now available.

Pulsar Helium Inc. has announced that two U.S. federal laboratories, the U.S. Geological Survey and Lawrence Livermore National Laboratory, have independently confirmed the presence and concentration of helium-3 at its Topaz project in Minnesota, with results closely matching earlier findings from the Woods Hole Oceanographic Institution. The labs reported helium-3 levels of approximately 11.2–11.9 parts per billion associated with around 8% helium-4 and a consistent isotopic ratio across all measurements, placing Topaz among the richest known terrestrial sources of helium-3 and validating Pulsar’s earlier data. Using rigorous copper-tube sampling and interlaboratory comparison, the confirmation significantly strengthens the scientific credibility and strategic importance of the discovery, and the company says it now plans to engage with U.S. government agencies on potential participation in developing Topaz as a new domestic source of this rare and high-value isotope.
