Pulsar Helium says Lake County project confirms rare helium-3 levels

Pulsar Helium said on June 23 that President Cliff Cain will present at the 2026 Quantum Tech World conference in Boston, where he plans to discuss independent verification of helium-3 at the Topaz Project in northeastern Minnesota. Two U.S. federal laboratories independently confirmed the isotope concentration from gas produced at Jetstream #1.

Jetstream #1 samples showed helium-3 concentrations ranging from 1.3 to 14.5 parts per billion. Jetstream #1 gas averaged 8.1% helium-4, with peaks up to 11.4%, while Jetstream #2 averaged 5.6% helium. Pulsar has said the 3He/4He ratio points to detectable mantle helium-3, and the readings are among the highest naturally occurring terrestrial helium-3 levels it has publicly reported.

In June 2026, Pulsar said it acquired about 1,360 acres of surface land in Lake County for roughly $2.4 million, adding to the Topaz property it says is 100% owned and its flagship project in Minnesota. The Topaz occurrence was first intersected in 2011 by a nickel explorer drilling for something else, when helium-rich gas was encountered by chance. Pulsar later said Jetstream #1 reached total depth of 5,100 feet in January 2025.

All Jetstream wells drilled to date have encountered high-pressure gas, and Pulsar is seeking quotes for up to four new production wells to supplement two production-ready wells already drilled. Minnesota adopted a helium-specific regulatory framework on May 28, 2026, and Pulsar welcomed the move as advancing Topaz toward first production amid a global helium shortage.
