DiagnaMed Holdings to Rebrand as GeoHydrogen Corp. to Highlight Focus on Natural Clean Hydrogen Development

Strategic Motivation for Corporate Rebranding

The proposed rebranding to GeoHydrogen Corp. signals DiagnaMed’s strategic shift to focus exclusively on natural clean hydrogen exploration and development. The company states this change aims to clearly communicate its dedication to geologic hydrogen—a naturally occurring hydrogen resource—to investors, partners, and stakeholders. The new name better aligns with the company’s mission, assets, and operational focus within the natural hydrogen sector.

This announcement coincides with growing recognition of natural clean hydrogen as a key element in the global clean energy transition. Unlike manufactured "grey" or "blue" hydrogen, geologic hydrogen is a low-carbon, naturally replenishing resource that does not require energy-intensive production processes, offering the potential for abundant and cost-effective clean energy. By adopting this new corporate identity, DiagnaMed positions itself strategically within this emerging energy market.

Temiskaming Natural Hydrogen Project in Ontario

The Temiskaming Natural Hydrogen Project is a central asset in DiagnaMed’s portfolio. Soil-gas exploration has identified an approximately 11-kilometre corridor with anomalous hydrogen concentrations surpassing 2,000 ppm, indicating significant geochemical activity consistent with natural hydrogen systems.

The company plans to release infill soil gas results from the Temiskaming corridor during the current field season, marking a series of exploration catalysts expected to advance the project toward defining priority drill targets. This focus underscores DiagnaMed’s commitment to systematically characterizing promising natural hydrogen zones within established geological frameworks.

Colchester East Natural Hydrogen Project in Nova Scotia

DiagnaMed’s recently acquired Colchester East Natural Hydrogen Project includes 30 exploration licences covering 2,104 mineral claims within the prospective Cumberland Basin in Nova Scotia. This acquisition expands the company’s footprint beyond Ontario and marks its entry into Nova Scotia’s natural hydrogen exploration landscape. The Cumberland Basin is identified as a promising geological environment for natural hydrogen discovery.

The company expects to produce the first systematic geochemical dataset from Colchester East during the current field season, supporting the identification of priority drill targets and advancing the project from regional reconnaissance to detailed exploration. The ongoing partnership with QIMC will guide these efforts.

Continued Collaboration with Québec Innovative Materials Corp.

DiagnaMed reaffirms its strategic technical advisory relationship with Québec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ), recognized as a leading natural hydrogen exploration company in North America. QIMC has developed one of the continent’s most advanced natural hydrogen datasets and will continue to provide expertise for both Ontario and Nova Scotia projects.

QIMC’s proprietary R2G2™ (Reactivated Rift and Graben Geostructure) exploration framework integrates structural geology, soil gas geochemistry, geophysics, and proprietary targeting models to identify naturally occurring hydrogen systems. This methodology has been applied across multiple sedimentary basins including Québec, Ontario, Nova Scotia, and Minnesota. QIMC’s advisory services to DiagnaMed include exploration planning, field program oversight, soil gas sampling, geoscientific interpretation, structural analysis, and integration of geological and geochemical data to generate drill targets.

New Trading Symbol and Shareholder Information

Once the CSE approves the name change, DiagnaMed’s common shares are expected to trade under the new ticker "GEOH" on the Canadian Securities Exchange. The company’s U.S. OTCQB symbol will be updated accordingly, and a new CUSIP number will be assigned upon completing the corporate name change. Existing share certificates will remain valid and do not require exchange after the effective date.

The company emphasizes that the name change will not impact the number of common shares outstanding. The change remains subject to CSE acceptance and applicable corporate approvals, including shareholder consent. The announcement does not specify the timeline for these regulatory and corporate approvals.

Natural Clean Hydrogen: A Growing Energy Frontier

DiagnaMed’s strategic focus on natural clean hydrogen is founded on the increasing recognition of geologic hydrogen as a vital clean energy resource. The company describes naturally occurring hydrogen generated within the Earth’s crust as "one of the most compelling frontiers in the global clean energy transition." Unlike manufactured "grey" or "blue" hydrogen, geologic hydrogen is a low-carbon, naturally replenishing resource that requires no energy-intensive production.

This positioning aligns with broader industry trends recognizing natural hydrogen’s potential to aid decarbonization. By concentrating exclusively on natural clean hydrogen exploration and development, DiagnaMed aligns its corporate strategy with a significant growth opportunity in the global energy transition. The proposed rebranding to GeoHydrogen Corp. clearly communicates this strategic focus to investors and stakeholders.

Upcoming Exploration Catalysts and Activities

The company anticipates a "steady flow of exploration catalysts" throughout the current field season as it progresses the Temiskaming project in Ontario and the Colchester East project in Nova Scotia toward defined drill targets. Key upcoming milestones include infill soil gas results from Temiskaming and the first systematic geochemical dataset from Colchester East. These updates are expected to provide significant insights into the company’s exploration progress.

CEO John Karagiannidis commented, "The proposed name change to GeoHydrogen marks the beginning, alongside QIMC, of our most active exploration period yet," adding that the company looks forward to sharing meaningful results in the coming months as both projects advance. Specific timing and details of these updates were not disclosed.

Corporate Governance and Regulatory Process

The name change from DiagnaMed Holdings Corp. to GeoHydrogen Corp. is contingent upon CSE approval and applicable corporate approvals, including shareholder consent. The company has not provided a timeline for these approvals or an effective date for the name change.

Until the change is finalized, the company will continue operating under DiagnaMed Holdings Corp., with shares trading under DMED on the CSE and DGNMF on the OTCQB. The announcement does not indicate whether a formal application has been submitted to the CSE or the expected duration of the regulatory review.

Management’s Outlook on Shareholder Value Creation

In his remarks, CEO John Karagiannidis emphasized that the company’s evolution into a focused natural clean hydrogen developer justifies a corporate name that accurately reflects its identity and mission. He stated, "GeoHydrogen captures both the science and the promise of our work — identifying naturally occurring, clean hydrogen systems within the Earth." This underscores the importance of rebranding in communicating the company’s strategic direction and enhancing long-term shareholder value.

The CEO reaffirmed the company’s commitment to advancing its Ontario and Nova Scotia portfolios alongside QIMC. By positioning itself firmly within the natural hydrogen exploration sector and securing a focused portfolio supported by an experienced technical partner, DiagnaMed pursues a strategy centered on disciplined scientific exploration and the potential identification of drill-ready natural hydrogen targets. The success of this approach will depend on forthcoming exploration results from the Temiskaming and Colchester East projects.
