Highlights

  • PFS confirms geothermal system at Tunu with 80-130°C reservoir and 0.8% helium.
  • Flow rates up to 720 m³/hour could supply Ittoqqortoormiit and ~350,000 cubic feet helium/day.
  • Exclusive Mineral Exploration Licence 2025/101; new airport at Ittoqqortoormiit planned for 2026.

Pulsar Helium Inc. (LSE:PLSR) is a publicly traded helium exploration company. Its portfolio includes the Topaz project in Minnesota, USA, and the Tunu project in Greenland. Pulsar is the first mover in both locations, with primary helium occurrences unassociated with hydrocarbons.

Project Overview
the company announced promising pre-feasibility results for its Tunu helium-geothermal project in East Greenland. The project is located near Ittoqqortoormiit and is among the few primary helium occurrences in Europe, with helium concentrations in hot springs up to 0.8%. Reservoir temperatures are estimated between 80-130°C, supporting both renewable power generation and helium extraction.

Pre-Feasibility Study Findings
An independent study by Sproule-ERCE identified an active geothermal system beneath Liverpool Land. Reservoir modelling suggests potential flow rates up to 720 m³/hour, sufficient to supply electricity to the local settlement while enabling helium production. In high-case scenarios, daily helium recovery could reach ~350,000 cubic feet. Binary cycle and dual-flash geothermal power systems were highlighted as feasible, with estimated capital costs of USD 20-30M.

Project Development and Infrastructure
The Tunu Project holds exclusive Mineral Exploration Licence 2025/101 and is fully permitted for long-term development. The Greenland and Danish governments have funded a new airport at Ittoqqortoormiit, scheduled for 2026, improving year-round access and logistics. Pulsar has conducted seismic surveys and hot spring sampling, confirming fractured reservoirs suitable for helium and geothermal fluid flow.

Outlook and Next Steps
Planned 2026 activities include magneto-telluric surveys, further hot spring sampling, and a slim appraisal well to directly assess reservoir conditions. These steps will refine project design, support potential helium plant development, and strengthen confidence for investors and partners.

Management Comment
Thomas Abraham-James, President & CEO, said: "The results of this independent Pre-Feasibility study, combined with the announcement of a new airport at Ittoqqortoormiit, highlight the extraordinary potential of the Tunu Project. Tunu is not only one of the very few primary helium prospects in Europe, but also a project that aligns perfectly with Greenland and Europe's future energy and critical raw material needs.

With minimal existing infrastructure in East Greenland, the ability to power our planned helium plant directly from geothermal energy is transformative, delivering clean, baseload electricity to the local community while simultaneously reducing our operational expenses as we develop a pathway towards sustainable helium production. This unique synergy of renewable power and critical resource development positions Pulsar to both support the Greenlandic community with reliable energy and deliver helium to global markets at a time of growing strategic demand. We are excited to advance into the next phase of exploration and unlock the significant opportunities at Tunu."
