Pulsar Helium talks Tunu prefeasibility study results

Executive Summary

• Independent prefeasibility study by Sproule‑ERCE confirms geothermal reservoir potential and a viable primary helium resource at the Tunu project in East Greenland.
• High‑case scenarios estimate up to 720 m³/hr fluid flow, supporting both community power needs and helium production of ~350,000 cf/d.
• Capital cost for combined geothermal‑helium plant estimated at US$20‑30 million; new airport funding announced to improve logistics starting 2026.

Key Details

• Reservoir Temperatures: Estimated 80 °C – 130 °C based on geochemical and geophysical data.
• Flow Potential: Up to ~720 m³/hr in best‑case scenarios, sufficient to supply the entire settlement of Ittoqqortoormiit with clean electricity.
• Helium Production Estimate: High‑case recovery of ≈350,000 cf per day – one of Europe’s most prospective primary helium opportunities (non‑hydrocarbon associated).
• Power Generation Options: Binary‑cycle and dual‑flash geothermal systems identified as feasible; a single well pair could provide ~4.2 MW for both community power and helium processing.
• Capital Expenditure: Estimated US$20 million – US$30 million for integrated plant (geothermal power + helium separation).
• Infrastructure Development: Greenland and Denmark governments to fund a new airport at Ittoqqortoormiit; construction slated 2026‑2029, enhancing year‑round access and reducing logistics costs.
• Exploration History:
• Hot‑spring samples show helium concentrations up to 0.8 % (one of the highest in Europe).
• 2024 passive seismic survey identified two low‑velocity anomalies (50–200 m depth) coincident with hot springs and fault systems, indicating fractured reservoirs.
• Licensing: Holds exclusive mineral exploration licence 2025/101 (initial term 5 years, extendable to 22 years) covering the entire Tunu project area.
• Next Steps Recommended by Sproule‑ERCE: Focused 2026 program including magnetotelluric surveys, additional hot‑spring sampling, and a slim appraisal well to directly measure reservoir conditions.
