DIAGNAMED AND QIMC CONFIRM MAJOR DISCOVERY OF WIDESPREAD NATURAL HYDROGEN SYSTEM IN ONTARIO'S TEMISCAMINGUE GRABEN

Diagnamed Holdings Corp. and Quebec Innovative Materials Corp. have made a major natural hydrogen discovery within Ontario's Temiscamingue graben. The first set of analytical results confirms widespread hydrogen anomalies across the northern section of the graben.

Of the 456 soil-gas samples analyzed to date, from the first four of ten survey lines, 209 exceeded 500 parts per million H2, with multiple readings surpassing 2,000 ppm and an average concentration of 558 ppm. These findings establish a strong indication of a regionally active natural hydrogen system extending west from Quebec into Ontario -- forming the foundation of the emerging Ontario-Quebec natural hydrogen corridor.

"This discovery represents a defining milestone for Diagnamed's clean-tech portfolio," said John Karagiannidis, president and chief executive officer of Diagnamed. "It validates our strategy to leverage natural hydrogen systems not only for energy production, but also as the backbone of future clean energy technology ecosystems -- including off-grid power solutions, AI data centres and next-generation energy infrastructure. We are witnessing the early stages of a new energy paradigm in Ontario."

Key results

• 456 soil-gas samples collected across four survey lines (lines 1-4) between July 8 and July 21, 2025;

• 209 samples and 500 ppm H2 -- average concentration: 558 ppm; median: 456 ppm;

• Multiple high readings: 1936 ppm and 2,205 ppm (line 1), 2,076 ppm (line 3), 2,098 ppm, 2,100 ppm, 2255 ppm and 2,458 ppm (line 4);

• Hydrogen anomalies correlate with deep-seated fault systems and structural discontinuities beneath Quaternary sediments in the Blanche River Valley;

• Program conducted under the technical direction of the Institut national de la recherche scientifique (INRS) led by Professor Marc Richer-Lafleche.

Geological and scientific significance

The survey area covers the Northern Ontario extension of the Temiscamingue graben, a Proterozoic-Paleozoic corridor where carbonate, dolomitic and siliciclastic formations overlie the cobalt group and Nipissing mafic dikes -- lithologies known for their permeability and hydrogen-generating potential. These results demonstrate that hydrogen is actively migrating through fault-controlled structures, aided by shallow groundwater circulation beneath clay-silt Quaternary sediments.

"The hydrogen concentrations recorded in Ontario are unusually high for a regional soil-gas survey," said Prof. Richer-Lafleche. "With an average of 558 ppm and over 200 samples above 500 ppm, the statistical consistency and geological alignment confirm the Temiscamingue graben as a promising domain for hydrogen generation, migration and possible trapping."

Community and indigenous partnership

Diagnamed and QIMC acknowledge the Temiscamingue First Nation (TFN) and local Ontario communities for their collaboration and support throughout the program. This partnership was recently formalized through a memorandum of understanding (MOU) recognizing that the exploration area lies within TFN's traditional hunting and cultural territories. The MOU establishes a framework for mutual respect, environmental stewardship and shared economic benefits-including local employment and participation in future project development.

Next steps

The companies are advancing to the next phase of the Ontario exploration program, which will include additional soil-gas survey lines extending westward along the Temiscamingue grabenHigh-resolution AMT and magnetic surveys, coupled with radon-thoron gas mapping.

"We are not only mapping hydrogen -- we are defining the foundations of Ontario and Quebec's clean energy economy," added Mr. Karagiannidis. "This is how natural hydrogen transitions from discovery science to commercial-scale energy integration."
