Pulsar Helium announces Helium-3 Discovery at Jetstream #1, Topaz Project, Minnesota

Executive Summary

• Pulsar Helium announced a landmark discovery of helium‑3 (³He) at its Topaz Project in Minnesota, with laboratory analyses showing sustained concentrations up to 14.5 ppb – among the highest naturally occurring ³He levels ever reported for a terrestrial gas reservoir.
• The Jetstream #1 well also produced 7–8 % helium‑4 (⁴He) and demonstrated a peak flow of ~1.3 MMcf/d, confirming both high‑grade conventional helium and an unprecedented ³He enrichment.
• Pulsar highlighted the strategic significance of this find for fusion energy, quantum computing, neutron detection, and national security, positioning the Topaz Project as a potential domestic source of a rare isotope currently valued at up to US $18.7 million per kilogram.

Key Details

• Helium‑3 Concentrations: 1.3 – 14.5 ppb in produced gas; isotopic ratio ³He/⁴He ≈ 0.09 Rₐ (consistent across multiple labs).
• Helium‑4 Content: Sustained flow containing 7–8 % He‑4; peak wellhead flow ~1.3 MMcf/d during August 2025 test.
• Well Information: Jetstream #1 appraisal well depth = 5,100 ft (1,555 m); Jetstream #2 depth = 5,638 ft (1,718 m). Drilling campaign to expand the reservoir slated for early October 2025.
• Analytical Verification: Samples analyzed by Smart Gas Sciences LLC (Ohio) using Thermo Helix SFT mass spectrometer and independently verified by Woods Hole Oceanographic Institution (WHOI) with a Nu Instruments multi‑collector Noblesse system; both labs accredited and results cross‑checked.
• Comparative Context: Peer discovery in Australia reported sub‑ppb ³He levels; volcanic settings (e.g., East Pacific Rise) show higher ratios but low absolute He volumes, making Topaz’s find uniquely commercial‑grade.
• Strategic Value: ³He market price ~US $2,500 per liter (~US $18.7 million/kg); applications include fusion fuel (D‑³He), quantum computing cryogenics, neutron detection for security/research, and advanced low‑temperature cooling.
• Commercial Outlook: No current commercial ³He/⁴He separation technology at scale; Pulsar is engaging potential partners to develop separation processes and invites collaboration from research groups and technology developers.
• Forward‑Looking Statements: Company expects to advance Topaz toward production, target a plant construction contract in 2026, and make a final investment decision the same year; estimates of helium volumes remain un‑risked contingent/prospective figures subject to technical and market uncertainties.
