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

Executive Summary

• Québec Innovative Materials Corp. (QIMC) and DiagnaMed Holdings Corp. (DMED) announced the first set of results from their Ontario natural hydrogen exploration program, revealing widespread hydrogen anomalies across the northern Témiscamingue Graben.
• Of 456 soil‑gas samples collected on four survey lines, 209 samples recorded H₂ concentrations > 500 ppm, with multiple readings exceeding 2,000 ppm and an average concentration of 558 ppm, indicating a robust, regionally active hydrogen degassing system.
• The companies plan to expand the program in 2026 with additional soil‑gas lines, high‑resolution AMT/magnetic surveys, radon‑thoron measurements, and preliminary site selection for drilling.

Key Details

• Sampling Overview: 456 soil‑gas samples collected between July 8–21, 2025 on Lines 1‑4 of the Ontario extension of the Témiscamingue Graben.
• High‑Concentration Results:
• 209 samples > 500 ppm H₂ (≈46% of total).
• Average concentration: 558 ppm; median: 456 ppm.
• Peak readings: 1,936 ppm & 2,205 ppm (Line 1); 2,076 ppm (Line 3); 2,098‑2,458 ppm (Line 4).
• Geological Interpretation: Anomalies are closely associated with deep structural discontinuities beneath Quaternary sediments in the Blanche River Valley, supporting a continuous natural hydrogen system linked to Quebec discoveries.
• Program Leadership: Conducted by the Institut national de la recherche scientifique (INRS) under Prof. Marc Richer‑Laflèche.
• Indigenous & Community Collaboration: Formalized Memorandum of Understanding with Témiscamingue First Nation, establishing a framework for cooperative exploration, local employment, environmental stewardship, and shared economic benefits.
• Next Steps (2026):
• Extend soil‑gas surveys westward along the Graben.
• Deploy high‑resolution AMT and magnetic surveys plus radon‑thoron measurements to refine subsurface mapping.
• Commence preliminary site selection for drilling.
• Integrate Ontario data into QIMC’s Ontario‑Québec Hydrogen Corridor Model.

Notable Quotes

• “The density and strength of these anomalies—nearly half of all samples above 500 ppm—confirm that Ontario hosts an active natural hydrogen system directly continuous with our Quebec discoveries,” – John Karagiannidis, President & CEO, QIMC.
• “The statistical distribution of hydrogen concentrations… is exceptionally high for a regional soil‑gas survey… confirming that the Témiscamingue Graben hosts the geological features required for hydrogen generation, migration, and trapping,” – Prof. Marc Richer‑Laflèche, INRS.
