DIAGNAMED ADVANCES NEXT PHASE OF CANADIAN NATURAL HYDROGEN EXPLORATION WITH QIMC ACROSS ITS ONTARIO AND NOVA SCOTIA PROJECTS

Diagnamed Holdings Corp. has extended its strategic technical advisory agreement with Quebec Innovative Materials Corp. to accelerate advancement of its Canadian natural hydrogen portfolio toward increasingly refined exploration targets. Under the renewed agreement, Quebec Innovative Materials will continue advancing the company's Temiskaming natural hydrogen project in Ontario through the densification of previously identified hydrogen anomalies while initiating the first systematic soil gas exploration program on Diagnamed's newly acquired Colchester East natural hydrogen project in eastern Nova Scotia. Together, these programs represent the next stage in Diagnamed's strategy of systematically evaluating prospective natural hydrogen systems in two of Canada's most promising hydrogen jurisdictions using a disciplined, science-driven exploration methodology. The extension reflects the continued advancement of Diagnamed's natural hydrogen strategy following a series of significant exploration milestones achieved over the past year.

Previous exploration programs completed in Ontario identified numerous naturally occurring hydrogen soil gas anomalies, including hydrogen concentrations exceeding 2,000 parts per million, across the Temiskaming project. Subsequent exploration and interpretation expanded the known hydrogen-bearing corridor to more than 11 kilometres, providing compelling evidence of a large-scale hydrogen system within the Temiskaming graben. These results have successfully advanced the project from regional reconnaissance to target refinement and established the foundation for a more detailed exploration phase focused on delineating priority exploration targets.

The next phase of work will consist of densification (infill) soil gas sampling and geophysics over priority hydrogen anomalies previously identified by Quebec Innovative Materials. The higher-density sampling grid is designed to better define anomaly geometry, improve understanding of the structural controls influencing hydrogen migration, and prioritize high-confidence targets for future exploration activities.

In parallel, Quebec Innovative Materials will commence the inaugural soil gas sampling program on Diagnamed's recently acquired Colchester East natural hydrogen project, comprising 30 exploration licences totalling 2,104 mineral claims within Nova Scotia's prospective Cumberland basin. The property is strategically located along the regional Cumberland fault system, a significant geological structure considered favourable for natural hydrogen generation and migration.

The Nova Scotia program will establish the first systematic geochemical data set across the property and assist in identifying areas warranting more detailed follow-up development.

Quebec Innovative Materials' advisory services include exploration planning, field program supervision, soil gas sampling, geoscientific interpretation, structural analysis, and the integration of geological and geochemical data sets to support drill target generation across both projects. Quebec Innovative Materials is recognized as Canada's leading natural hydrogen company and has pioneered exploration methodologies that integrate structural geology, soil gas geochemistry and proprietary targeting models to identify naturally occurring hydrogen systems. The company's technical team has successfully applied these methodologies across multiple Canadian sedimentary basins, including Quebec and Nova Scotia, where continuing exploration continues to expand the understanding of Canada's natural hydrogen potential.

John Karagiannidis, chief executive officer of Diagnamed, commented: "Our collaboration with QIMC has enabled Diagnamed to rapidly advance one of Canada's emerging natural hydrogen exploration portfolios. In Ontario, we have progressed from regional reconnaissance to defining an extensive hydrogen system that now warrants detailed infill exploration and geophysics. At the same time, our Colchester East acquisition provides exposure to another highly prospective geological setting within Nova Scotia's Cumberland basin. By advancing exploration programs in two of Canada's most prospective natural hydrogen jurisdictions, we are systematically evaluating multiple opportunities for naturally occurring hydrogen accumulations using a disciplined, science-driven exploration methodology. This next phase is focused on converting encouraging regional exploration results into increasingly refined targets that will guide future exploration programs while continuing to build long-term shareholder value."

The combination of advanced target refinement in Ontario and first-pass exploration in Nova Scotia provides Diagnamed with a diversified pipeline of exploration catalysts expected throughout the current field season.

Coming exploration milestones

The company expects the following exploration catalysts over the coming months:

• Completion of the Ontario infill soil gas sampling program;
• Completion of the inaugural Colchester East soil gas survey in Nova Scotia;
• Laboratory analysis of all soil gas samples;
• Integrated geological, structural and geochemical interpretation;
• Delineation of priority drill targets.
