8 min read | July 28, 2026 08:25 AM EDT | By Sonal Goyal

DiagnaMed Holdings Corp. (CSE: DMED) has revealed plans to rename itself GeoHydrogen Corp., pending regulatory approval, to better reflect its strategic emphasis on exploring and developing natural clean hydrogen resources in Canada. The company is progressing a portfolio of promising hydrogen projects in Ontario and Nova Scotia through a technical collaboration with Que9bec Innovative Materials Corp. (QIMC). Upon completion of the rebranding, shares are expected to trade under the new ticker "GEOH" on the Canadian Securities Exchange. This change underscores DiagnaMed's evolution into a dedicated natural hydrogen developer, offering shareholders enhanced clarity on the company’s direction as it advances toward defining drill-ready targets.

Key Points

  • DiagnaMed Holdings Corp. (CSE: DMED) plans to change its corporate name to GeoHydrogen Corp., subject to Canadian Securities Exchange approval and shareholder consent.
  • The company is advancing natural hydrogen initiatives including the Temiskaming Natural Hydrogen Project in Ontario—where soil-gas surveys have identified an 11-kilometre corridor with hydrogen levels exceeding 2,000 ppm—and the Colchester East Natural Hydrogen Project in Nova Scotia, encompassing 30 exploration licences totaling 2,104 mineral claims.
  • Following the name change, common shares are anticipated to trade under the new ticker "GEOH" on the CSE, with a new CUSIP to be announced; existing share certificates will remain valid.
  • DiagnaMed reaffirms its strategic technical advisory partnership with Que9bec Innovative Materials Corp. (CSE: QIMC), a leading North American natural hydrogen explorer, and expects ongoing exploration catalysts during the current field season, including infill soil gas data and geochemical analyses.

Strategic Rebranding to Emphasize Natural Hydrogen Exploration

On July 28, 2026, DiagnaMed Holdings Corp. announced its intention to adopt the name GeoHydrogen Corp. to clearly convey its exclusive focus on geologic, naturally occurring hydrogen exploration and development. This rebranding aims to provide investors, partners, and stakeholders with an immediate and precise understanding of the company’s mission and market positioning. Natural clean hydrogen—hydrogen generated within the Earth’s crust—is gaining recognition as a pivotal element in the global clean energy transition.

The name "GeoHydrogen" directly aligns with the company’s goal of discovering naturally occurring clean hydrogen systems underground. Over the past year, DiagnaMed has built a promising project portfolio and established a technical partnership with Que9bec Innovative Materials Corp., a recognized leader in natural hydrogen exploration in North America. The company believes this rebrand will better communicate its strategic direction and enhance shareholder value.

Core Projects: Temiskaming and Colchester East Natural Hydrogen Ventures

DiagnaMed’s portfolio now centers on two highly prospective natural hydrogen projects in Canada’s key jurisdictions. The Temiskaming Natural Hydrogen Project in Ontario features an approximately 11-kilometre corridor identified through soil-gas surveys with hydrogen concentrations exceeding 2,000 ppm, indicating a significant geologic hydrogen system warranting further drilling.

The recently acquired Colchester East Natural Hydrogen Project in Nova Scotia includes 30 exploration licences covering 2,104 mineral claims within the Cumberland Basin. This expansion diversifies the company’s geographic presence across distinct geological environments, each with strong potential for natural hydrogen accumulation. Supported by QIMC’s technical expertise and proprietary exploration methods, DiagnaMed is advancing both projects from initial reconnaissance toward defined drill targets.

Partnership with Que9bec Innovative Materials Corp. and R2G21 Exploration Methodology

DiagnaMed reaffirmed its strategic technical advisory partnership with Que9bec Innovative Materials Corp. (CSE: QIMC) (OTCQB: QIMCF) (FSE: 7FJ), a leading natural hydrogen exploration company in North America. QIMC brings extensive expertise and one of the continent’s most advanced natural hydrogen datasets, supporting DiagnaMed’s project advancement in Ontario and Nova Scotia.

QIMC utilizes its proprietary R2G21 (Reactivated Rift and Graben Geostructure) exploration framework, integrating structural geology, soil gas geochemistry, geophysics, and proprietary targeting models to identify natural hydrogen systems. This methodology has been applied across multiple sedimentary basins in Que9bec, Ontario, Nova Scotia, and Minnesota, providing robust guidance for DiagnaMed’s exploration programs. QIMC’s advisory role includes exploration planning, field supervision, soil gas sampling, geoscientific interpretation, structural analysis, and dataset integration to support drill-target generation for both core projects.

Understanding Natural Clean Hydrogen Versus Conventional Hydrogen Sources

The company clarified that natural clean hydrogen is distinct from traditional hydrogen production methods. It is a low-carbon, naturally replenishing resource formed within the Earth’s crust, requiring no energy-intensive manufacturing processes. Unlike "grey" or "blue" hydrogen produced industrially, geologic hydrogen emerges from natural geological processes, offering potential for abundant and cost-effective clean energy.

This differentiation is crucial for investors assessing the company’s strategic pivot. Natural hydrogen represents a fundamentally new opportunity in the clean energy sector. DiagnaMed’s focus on identifying naturally occurring hydrogen systems, combined with a rigorous scientific exploration approach, underpins a long-term investment thesis centered on the commercial scalability of geologic hydrogen in Canada.

New Ticker Symbol and Shareholder Impact

Pending Canadian Securities Exchange approval and corporate authorizations, DiagnaMed’s common shares are expected to trade under the ticker symbol "GEOH" on the CSE. The company’s U.S. OTCQB symbol will be updated accordingly, with a new CUSIP number to be announced upon completion of the name change. This ticker change aligns with the company’s renewed corporate identity and strategic focus.

The name change will not affect the number of outstanding common shares, and existing share certificates will remain valid without requiring exchange. This ensures a smooth transition for shareholders, maintaining continuity of ownership throughout the rebranding process. Final implementation depends on CSE acceptance and shareholder approval, so the effective date remains pending.

Exploration Milestones Anticipated During Current Field Season

DiagnaMed anticipates a series of exploration catalysts in the current field season, including infill soil gas results from the Temiskaming corridor and the first systematic geochemical dataset from Colchester East. These data are expected to facilitate advancement toward priority drill targets, marking a shift from early reconnaissance to more advanced exploration stages.

CEO John Karagiannidis described the name change as "the beginning, alongside QIMC, of our most active exploration period yet," expressing optimism about delivering meaningful results in the coming months. Investors can expect updates on geochemical data, structural analyses, and drill-target identification as the company progresses through 2026 and into 2027.

Regulatory and Shareholder Approval Process

The proposed GeoHydrogen Corp. name change is subject to Canadian Securities Exchange acceptance and shareholder approval. The announcement did not specify timelines for these approvals, leaving the exact rebranding date uncertain. Investors should monitor future company communications for updates on the approval process and any conditions imposed by the CSE.

No shareholder meeting scheduling or CSE acceptance dates were disclosed in the July 28, 2026 announcement. Stakeholders are advised to stay informed through upcoming filings and news releases regarding the progress of the name and ticker symbol change.

Positioning GeoHydrogen for Growth in the Natural Hydrogen Market

DiagnaMed’s rebranding to GeoHydrogen Corp. aligns with a growing industry recognition of natural hydrogen as a key emerging opportunity within clean energy. The new corporate identity aims to clearly position the company within this sector and communicate its strategic vision to investors, partners, and stakeholders. The company views the rebrand as critical to long-term capital raising and partnership development.

The GeoHydrogen name enhances investor recognition and clarifies the company’s business model, distancing it from its previous medical diagnostics associations under the DiagnaMed brand. For investors seeking exposure to Canada’s natural hydrogen exploration sector, this rebranding facilitates clearer market identification. The company emphasizes its commitment to responsible exploration and scalable natural hydrogen development within commercial and environmental frameworks.

Shareholder Considerations Amid the Rebranding

Shareholders will experience continuity throughout the name change, with existing share certificates remaining valid and no changes to share count or dilution indicated. Post-rebrand, shares will trade under the new ticker "GEOH" instead of "DMED," which may require updates to trading platforms and portfolio management tools.

The announcement did not provide guidance on share price impact. Investors should monitor market reactions to the rebrand and forthcoming exploration results. The clarified strategic focus and enhanced corporate identity may influence investor sentiment and trading activity, though no explicit valuation implications were stated.

Exploration Timeline and Upcoming Developments

While specific dates for shareholder approval and CSE acceptance remain undisclosed, DiagnaMed anticipates a "steady flow of exploration catalysts" throughout the current field season. This indicates ongoing data releases and progress updates rather than a single major event. The company aims to accelerate exploration beyond early soil gas surveys at Temiskaming toward defined drill targets.

Investors should watch for updates on shareholder approval, CSE acceptance of the "GEOH" ticker, infill soil gas results from Temiskaming, initial geochemical data from Colchester East, and drill-target announcements. The partnership with QIMC ensures exploration decisions will be guided by advanced technical expertise, supporting high-quality drill-target selection.
