DiagnaMed and QIMC Confirm Major Discovery of Widespread Natural Hydrogen System in Ontario's Temiscamingue Graben

Executive Summary

• DiagnaMed Holdings Corp. and Québec Innovative Materials Corp. reported that 209 of 456 soil‑gas samples (≈46%) from the Ontario extension of the Témiscamingue Graben contain >500 ppm hydrogen, with multiple readings exceeding 2,200 ppm.
• The results define a regionally active natural hydrogen system that could become the core of an emerging Ontario‑Québec Natural Hydrogen Corridor.
• Companies announced next‑phase work—including additional soil‑gas lines, high‑resolution AMT/magnetic surveys, radon‑thoron mapping and preliminary drilling target selection for 2026—while formalizing a partnership with the Témiscamingue First Nation via an MOU.

Key Details

• Sample Scope: 456 soil‑gas samples collected across four initial survey lines (Lines 1‑4) between 8–21 July 2025.
• High‑Hydrogen Incidence: 209 samples (>500 ppm H₂); average concentration 558 ppm; median 456 ppm.
• Peak Readings:
• Line 1 – 1,936 ppm and 2,205 ppm
• Line 3 – 2,076 ppm
• Line 4 – 2,098 ppm, 2,100 ppm, 2,255 ppm, 2,458 ppm
• Geological Context: Anomalies align with deep‑seated fault systems and structural discontinuities beneath Quaternary sediments in the Blanche River Valley; the area sits within carbonate, dolomitic, and siliciclastic formations overlying the Cobalt Group and Nipissing mafic dykes—lithologies known for permeability and hydrogen generation potential.
• Technical Oversight: Program directed by INRS (Institut national de la recherche scientifique) under Prof. Marc Richer‑Laflèche.
• Scientific Significance: Confirms active migration of natural hydrogen through fault‑controlled structures, aided by shallow groundwater flow beneath clay‑silt sediments.
• Community & Indigenous Partnership: Formal MOU with the Témiscamingue First Nation establishing mutual respect, environmental stewardship, and shared economic benefits (local employment, participation in future development).
• Next Steps (2026 Planning):
• Extend soil‑gas surveys westward along the Graben.
• Conduct high‑resolution Airborne Magnetics (AMT) and magnetic surveys plus radon‑thoron gas mapping.
• Identify preliminary drilling sites for 2026 field program.
• Integrate Ontario data into a cross‑border Ontario‑Québec Hydrogen Corridor model.

Notable Quotes

• John Karagiannidis, President & CEO, DiagnaMed: “This discovery represents a defining milestone for DiagnaMed's clean‑tech portfolio… We are witnessing the early stages of a new energy paradigm in Ontario.”
• Prof. Marc Richer‑Laflèche, INRS: “The hydrogen concentrations recorded in Ontario are unusually high for a regional soil‑gas survey… The statistical consistency and geological alignment confirm the Témiscamingue Graben as a promising domain for hydrogen generation, migration, and possible trapping.”
