DiagnaMed and QIMC Confirm Major Expansion of Hydrogen Zone by Over 11 Kilometers in Ontario's Temiscamingue Graben

Executive Summary

• DiagnaMed and Québec Innovative Materials announced soil‑gas survey results confirming a northward extension of the natural hydrogen system in Ontario’s Témiscamingue Graben by >11 km.
• 454 samples were analyzed; 251 exceeded 500 ppm H₂, including 116 above 1,000 ppm and a peak of 2,817 ppm, indicating a large, structurally controlled degassing zone.
• The company is engaging the Témiscamingue First Nation on an AI data‑infrastructure project powered by off‑grid natural hydrogen, positioning the corridor as a clean‑energy and digital hub.

Key Details

• Survey Scope: 4 new lines (Lines 5‑8) covering 45.3 km; total surveyed area ≈260 km² across Ontario municipalities of Couttsville, Thwaites, and Belle‑Vallée.
• Sample Results:
• 251 samples > 500 ppm H₂
• 116 samples > 1,000 ppm H₂
• 19 samples > 2,000 ppm H₂
• Highest concentration recorded: 2,817 ppm H₂
• Spatial Trend: Hydrogen concentrations increase toward the north; Lines 6‑8 show higher values than southern Lines 1‑4.
• Comparative Data: Median H₂ in Témiscamingue valley ≈375 ppm vs. 50‑125 ppm in Abitibi reference sites; many samples > 1,000 ppm not seen in Abitibi.
• Geochemical Context: Low methane (<3% of samples) and modest CO₂ (avg 0.6%) suggest minimal organic fermentation influence.
• Scientific Interpretation: High H₂ likely sourced from iron‑rich formations, optimal water supply, and reactivated Proterozoic tectonic structures facilitating hydrogen migration.
• Collaboration: Survey conducted with Institut National de la Recherche Scientifique (INRS) under Prof. Marc Richer‑Laflèche; research funded by FRQNT as part of a PhD thesis (Antoine Cuckovic).
• Strategic Outlook: Discussions underway with Témiscamingue First Nation to develop AI data‑center infrastructure powered by the identified hydrogen resource, aiming to create a clean‑energy hub and digital economy catalyst for Indigenous and local communities.

Notable Quotes

“These new results mark a significant milestone for DiagnaMed as we continue to advance the Ontario‑Quebec Hydrogen Corridor… This data strengthens our vision of merging clean‑tech with next‑generation computing solutions.” – John Karagiannidis, President & CEO, DiagnaMed

“The distribution of data, with a large number (47) hydrogen concentrations exceeding 1,500 ppm, is a clear indication of the hydrogen‑rich nature of the soils in the Témiscamingue valley.” – Prof. Marc Richer‑Laflèche
