DiagnaMed Holdings Corp. Announces Proposed Name Change to GeoHydrogen Corp., Aligning Its Corporate Identity with Its Strategic Focus on Natural Clean Hydrogen

DiagnaMed Holdings Corp. (CSE: DMED) (OTCQB: DGNMF) today announced its intention, subject to regulatory acceptance, to change its corporate name to GeoHydrogen Corp., to better align the Company's corporate identity with its strategic focus on natural clean hydrogen exploration and development.

Natural clean hydrogen — naturally occurring hydrogen generated within the Earth's crust — is emerging 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, offering the potential for abundant, low-cost clean energy.

Over the past year, the Company has assembled a focused portfolio of highly prospective natural hydrogen projects in two of Canada's most promising jurisdictions — the Temiskaming Natural Hydrogen Project in Ontario, where soil-gas exploration has identified an approximately 11-kilometre corridor of anomalous hydrogen readings, including concentrations exceeding 2,000 ppm, and the newly acquired Colchester East Natural Hydrogen Project in Nova Scotia, comprising 30 exploration licences totalling 2,104 mineral claims within the prospective Cumberland Basin.

With its business now focused exclusively on natural clean hydrogen exploration and development, the Company believes its corporate identity should more accurately reflect its strategic direction and long-term mission.

A Name Built for the Mission: GeoHydrogen Corp.

Accordingly, the Company intends to change its corporate name to GeoHydrogen Corp. The proposed name communicates the Company's exclusive focus on geologic — or naturally occurring — hydrogen, giving investors, partners and stakeholders an immediate and accurate understanding of its mission, its assets and the category in which it operates.

In connection with the change, the Company's common shares are expected, subject to CSE acceptance, to trade on the Canadian Securities Exchange under the proposed ticker symbol "GEOH". The Company's U.S. OTCQB symbol will be updated in due course. The name change remains subject to CSE acceptance and applicable corporate approvals.

Continued Strategic Partnership with QIMC

The Company also reaffirms its ongoing strategic technical advisory partnership with Québec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ) ("QIMC"), which will continue to guide exploration across both of the Company's Ontario and Nova Scotia projects. QIMC is recognized as one of North America's leading natural hydrogen exploration companies, technical adviser in natural hydrogen and a continental leader in the field, having assembled one of the most advanced natural hydrogen exploration datasets on the continent. Through its proprietary R2G2™ (Reactivated Rift and Graben Geostructure) exploration framework, QIMC integrates structural geology, soil gas geochemistry, geophysics and proprietary targeting models to identify naturally occurring hydrogen systems. QIMC has applied these methodologies across multiple sedimentary basins — including Québec, Ontario, Nova Scotia and Minnesota — making it the ideal technical partner as the Company advances its portfolio from regional reconnaissance toward defined drill t...
