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

Montreal, Quebec--(Newsfile Corp. - October 27, 2025) - Québec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) is pleased to announce that new soil-gas survey results from the Ontario section of the Témiscamingue Graben have confirmed a major northward extension of the natural hydrogen system by more than 11 kilometers.

A total of 454 soil-gas samples were collected and analyzed across lines 5-8. Results show 251 samples exceeding 500 ppm hydrogen (H₂), including 116 above 1,000 ppm, 19 above 2,000 ppm, and a peak concentration of 2,817 ppm. The data clearly demonstrate that hydrogen concentrations intensify toward the north, confirming a vast, structurally controlled degassing system within the Ontario portion of the Témiscamingue Graben.

"These results mark another major milestone for QIMC in the Ontario-Quebec hydrogen corridor," said John Karagiannidis, President & CEO of QIMC. "We've confirmed that the hydrogen-bearing corridor extends more than 11 kilometers northward, with more than half of all samples exceeding 500 ppm and 19 surpassing 2,000 ppm—including a high of 2,817 ppm. This confirms a continuous, fault-controlled hydrogen system on a regional scale and reinforces Ontario's strategic role within the emerging Ontario–Quebec hydrogen corridor."

The survey, conducted in collaboration with the Institut National de la Recherche Scientifique (INRS) under the supervision of Prof. Marc Richer-Laflèche, continues to expand the scale and continuity of this fault-controlled hydrogen corridor.

"As part of our commitment to sustainable regional development, we are also advancing discussions with the Témiscamingue First Nation on establishing an AI data infrastructure project powered by off-grid natural hydrogen energy," said John Karagiannidis, President & CEO of QIMC. "This initiative aims to position the Ontario–Quebec Hydrogen Corridor as both a clean energy hub and a next-generation data resource center, enabling Indigenous and local communities to participate directly in the digital and energy economies of the future."

In the second phase of fieldwork conducted across the municipalities of Couttsville, Thwaites, and Belle-Vallée (Ontario), the INRS-QIMC team completed four new Soil-Gas survey lines totaling 45.3 km and 454 stations. These additional surveys, located north of Lines 1 to 4, were designed to confirm the high hydrogen concentrations observed to the south, particularly along Line 4.

The statistical distribution of the data measured along Lines 5 to 8 was compared with that of Lines 1 to 4 (Fig. 1). The presence of strong hydrogen concentrations was confirmed on Line 5. Overall, hydrogen (H₂) concentrations are generally higher along Lines 6 to 8 than in the southern portion of the survey area (Lines 1 and 2). This demonstrates a clear north–south variability in the natural hydrogen potential within the Ontario segment of the Témiscamingue Graben system. The distance separating Lines 4 and 5 is 1.6 km, and the survey area covering Lines 1 to 8 extends over 11.3 km along the north–south axis and 23 km east–west—representing an area of approximately 260 km².

"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. These new results confirm what had already been demonstrated in 2024 for the Quebec section of the graben, particularly around St-Bruno-de-Guigues (QIMC)," notes Professor Marc Richer-Laflèche. "To date, scientific literature does not report any comparable geological context showing both such high hydrogen concentrations and such a large areal distribution," observes Professor Richer-Laflèche. For the Témiscamingue Graben valley, this suggests a geological environment combining several essential elements for natural hydrogen generation:

• Iron-rich sources (iron formations, peridotites, basalts, Nippissing dykes);

• Optimal water supply (Ottawa River watershed); and

• Proterozoic tectonic structures reactivated during the Paleozoic and Cenozoic eras, allowing water to descend at depth and hydrogen to migrate upward into reservoirs (limestone and dolomitic rocks) or surface-reaching fractures.

It is important to emphasize that the Quaternary geological setting of the Témiscamingue valley, in both Ontario and Quebec, is dominated by a thick layer of fine-grained glaciolacustrine sediments. This layer may explain some of the hydrogen distribution characteristics observed in the valley, particularly the lateral spread of high hydrogen concentrations across broad areas.

Conceptually, the presence of groundwater and fine-grained Quaternary silty-clay sediments could favor the horizontal dispersion of hydrogen; however, the elevated concentrations suggest the substrate itself may be a hydrogen source. To verify this, new Soil-Gas data were compiled from three Abitibi regions (Duparquet, East Val-d'Or – airport sector, and Lake Villebon east of Val-d'Or) where volcanic and sedimentary rocks are also overlain by thick fine-grained glaciolacustrine sediments.

The comparison (Fig. 2) highlights the difference between hydrogen concentrations in the Témiscamingue Graben valley and those in the Abitibi sectors. The Abitibi sites show median hydrogen values of 50 to 125 ppm, whereas the Témiscamingue valley shows a median of 375 ppm, with numerous anomalous values above 1,000 ppm—levels not observed in Abitibi soils.

Consequently, the data available to date suggest that glaciolacustrine sediments are not the cause of the hydrogen enrichment observed in the Témiscamingue Graben valley. This conclusion is further supported by the near absence of measurable methane (CH₄ detected in fewer than 3% of samples) and moderate CO₂ concentrations (average 0.6%) in samples collected along Lines 1 to 8. These results minimize the role of potential fermentation of organic matter within the sediments.
