Pulsar Helium Inc. (AIM: PLSR, TSXV: PLSR, OTCQB: PSRHF) has announced the results of an independent Pre-Feasibility Study (PFS) for its Tunu Project in East Greenland. The study, conducted by Sproule-ERCE, confirms the potential of a geothermal reservoir and the possibility of helium extraction. This positions the company at the intersection of renewable energy supply and critical raw material production for the European market.
Helium and Geothermal energy: dual strategy in East Greenland
The Tunu Project is located near the settlement of Ittoqqortoormiit on Scoresby Sound. According to the PFS, temperatures between 80 and 130 degrees Celsius were identified underground. Analyses indicate that fault and fracture systems control the flow of geothermal fluids. In combination with the helium concentrations measured there, an integrated project could emerge that both supplies electricity from geothermal energy and separates helium from the extracted gases.
Modeling shows that under favorable conditions, flow rates of up to approximately 720 cubic meters per hour are possible. This would allow for the supply of clean energy to the local community while also creating the basis for the separation of helium. In an optimistic scenario, a daily helium production of approximately 350,000 cubic feet could be achieved – a value that could make the project one of Europe’s most promising primary helium sources.
Infrastructure and Cost Framework
The study examined various technical approaches, including binary-cycle and dual-flash systems for geothermal power generation. The capital requirement for corresponding facilities is estimated at 20 to 30 million US dollars. This provides a realistic framework for the development of a combined project involving energy production and helium extraction.
Another factor that could facilitate project development is the planned construction of an airport in Ittoqqortoormiit. The governments of Greenland and Denmark have pledged funds for it, with construction scheduled to begin in 2026. The new infrastructure is intended to ensure year-round accessibility and could significantly improve logistics as Pulsar builds towards production..
Progress and Next Steps for Pulsar Helium
Over the past eighteen months, Pulsar Helium has advanced the Tunu Project from a conceptual idea to a data-backed undertaking. Initial investigations of thermal springs revealed helium concentrations of up to 0.8 percent, one of the highest values measured in Europe. In 2024, a passive seismic survey at Cape Tobin followed, which revealed subsurface anomalies interpreted as potential storage and flow paths for helium-bearing fluids.
Based on these results, Sproule-ERCE was commissioned in 2025 to conduct the Pre-Feasibility Study. The company integrated geophysical, geochemical, and geological data into an overall model, which now forms the basis for further planning steps. An exploration program starting in 2026 is recommended, which includes geophysical measurements, further sampling, and an initial test drilling.
Significance of the Tunu Project
With the Tunu Project, Pulsar Helium is the first licensee for helium exploration in Greenland. The company holds the exclusive Mineral Exploration Licence 2025/101 with a term of five years, extendable up to 22 years. This provides Pulsar with a long-term basis for further development.
The project is significant not only for its geothermal potential but also because it is a rare primary helium deposit not associated with hydrocarbons or CO2. Against the backdrop of growing demand for helium in high-tech industries and the search for sustainable energy sources, Tunu could play a strategically important role in Europe. This increases the chance of another productive helium project for the company, alongside the exceptionally high-grade flagship Topaz Project in Minnesota, whose development is also already well advanced.
