Diagnamed, QIMC make natural hydrogen discovery in Ont.

The most recent news, released on October 14, 2025, by Diagnamed Holdings Corp. (DMED) and Quebec Innovative Materials Corp. (QIMC), announces a "Major Discovery of Widespread Natural Hydrogen System" in Ontario's Temiscamingue Graben. This follows the completion of an extensive soil sampling program, with results now analyzed by the Institut national de la recherche scientifique (INRS).

Key findings include: * Analysis of 456 soil-gas samples (from the first four of ten survey lines) showed 209 samples exceeding 500 parts per million (ppm) H2. * The average hydrogen concentration was 558 ppm H2, with a median of 456 ppm H2. * Multiple high readings surpassed 2000 ppm H2, reaching up to 2458 ppm H2 in some samples. * Professor Marc Richer-Lafleche of INRS stated these concentrations are "unusually high for a regional soil-gas survey" and confirm the Temiscamingue graben as a "promising domain for hydrogen generation, migration and possible trapping." * Hydrogen anomalies correlate with deep-seated fault systems and structural discontinuities. * The discovery is presented as a "defining milestone" for Diagnamed's clean-tech portfolio, validating its strategy for energy production and future clean energy technology ecosystems. * Next steps include additional soil-gas surveys, high-resolution geophysical surveys (AMT and magnetic), radon-thoron gas mapping, and preliminary site selection for drilling in 2026.

This news builds on two previous announcements from October 8, 2025, detailing a Memorandum of Understanding (MOU) signed with the Temiscamingue First Nation (TFN) and local Ontario communities. This MOU establishes a framework for mutual respect, environmental stewardship (integrating TFN's traditional knowledge), and shared economic benefits, laying a crucial foundation for development within TFN's traditional territory.

Prior to these, on September 30, 2025, Diagnamed announced the completion of the hydrogen soil sampling program in the Temiscamingue Graben and strengthened its leadership team with the appointment of Andre Turmel as Executive Chairman and Pam Sangster as Strategic Adviser. These appointments bring significant experience in renewable energy, natural resources, and stakeholder relations. The September 30 news had also indicated that results from the sampling program would be rolled out "in the coming weeks," which has now materialized with the October 14 announcement.

The latest news regarding the "Major Discovery of Widespread Natural Hydrogen System" is unequivocally materially positive and, for a company at this early stage of exploration, approaches "Game Changer" status.

1. Direct Validation of Core Strategy: This news provides robust scientific validation of Diagnamed's (and QIMC's) exploration efforts in natural hydrogen. The "unusually high" concentrations confirmed by an independent scientific institution (INRS) go beyond mere anomalies and suggest a genuinely active system with potential for significant hydrogen accumulation. This is a critical step in de-risking the geological model for natural hydrogen in the region.
2. Exceeds Expectations: The concentrations (average 558 ppm, up to 2458 ppm) are explicitly noted by the leading professor as "unusually high for a regional soil-gas survey." This indicates that the results have surpassed general expectations for such early-stage exploration, moving the project from conceptual to a substantiated prospect.
3. Clear Path to Development: The announcement of "preliminary site selection for drilling in 2026" provides a tangible, forward-looking milestone. Drilling is the next critical phase in validating commercial viability, and having a timeline set indicates confidence in the current findings. This is a significant improvement over simply completing a survey and analyzing data; it signifies progression to the next, more capital-intensive, but also more value-accretive stage.
4. Strategic Corridor Development: The confirmation of a widespread system forming the "foundation of the emerging Ontario-Quebec Natural Hydrogen Corridor" positions Diagnamed as a potential leader in a nascent, high-growth clean energy sector. This has long-term strategic implications for the company's market positioning.
5. Complementary Developments: The preceding news of strengthening the leadership team with highly experienced individuals and, more importantly, securing an MOU with the Temiscamingue First Nation, significantly de-risks future development. The TFN MOU is particularly crucial for any resource project in Canada, demonstrating a proactive approach to social license and responsible development, which is essential for project continuity and long-term success. These foundational steps enhance the overall positive impact of the technical discovery.

Given the early stage of the natural hydrogen industry and the company's exploration focus, these confirmed high-grade results, coupled with a defined next step towards drilling, represent a potentially transformative event. While it's still exploration and not yet a proven reserve, the scientific backing and the scale of the findings are highly impactful.

Diagnamed Holdings Corp. (DMED) is an exploration company focused on developing natural hydrogen resources. The company is actively working in collaboration with Quebec Innovative Materials Corp. (QIMC) to explore and develop a "Natural Hydrogen Corridor" spanning Ontario and Quebec, Canada.

The company's flagship project is the Temiscamingue Graben in Ontario (extending from Quebec). This project aims to identify and develop commercially viable natural hydrogen deposits. The region is geologically characterized by a Proterozoic-Paleozoic corridor with carbonate, dolomitic, and siliciclastic formations overlying cobalt group and Nipissing mafic dikes, lithologies known for permeability and hydrogen-generating potential. The current focus is on understanding the active migration of hydrogen through fault-controlled structures. The recent news confirms a major, widespread natural hydrogen discovery in this area, validating the company's exploration strategy and advancing it towards drilling.
