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

About this update from Diagnamed Holdings Corp.

209 of 456 Soil Samples Exceed 500 ppm Hydrogen (H2), Including Multiple Readings Over 2,000 ppm - A Major Step Toward Defining Ontario-Québec Natural Hydrogen Corridor Toronto, Ontario--(Newsfile Corp. - October 14, 2025) - DiagnaMed Holdings Corp. (CSE: DMED) (OTCQB: DGNMF) ("DiagnaMed" or the "Company") and Québec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC") are pleased to announce a major natural hydrogen discovery within Ontario's Témiscamingue 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 ppm 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 Québec into Ontario-forming the foundation of the emerging Ontario-Québec Natural Hydrogen Corridor. "This discovery represents a defining milestone for DiagnaMed's clean-tech portfolio," said John Karagiannidis, President & CEO 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 centers, and next-generation energy infrastructure. We are witnessing the early stages of a new energy paradigm in Ontario." Key Results Geological and Scientific Significance The survey area covers the northern Ontario extension of the Témiscamingue Graben, a Proterozoic-Paleozoic corridor where carbonate, dolomitic, and siliciclastic formations overlie the Cobalt Group and Nipissing mafic dykes-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. Marc Richer-Laflèche. "With an average of 558 ppm and over 200 samples above 500 ppm, the statistical consistency and geological alignment confirm the Témiscamingue Graben as a promi...
