DiagnaMed Advances Ontario Natural Hydrogen & Helium Program with Strategic Geological Targeting in Timiskaming Graben

Rhea-AI Summary

DiagnaMed Holdings Corp. (DGNMF) is advancing its natural hydrogen and helium exploration program in Ontario's Timiskaming district. The company, collaborating with INRS and Quebec Innovative Materials Corp., has begun reviewing geological data to identify high-priority targets across their claims. The exploration strategy focuses on areas with specific geological characteristics including Precambrian bedrock, Paleozoic formations, active rift systems, and fault systems conducive to gas migration. The program builds on a successful model previously used in the St-Bruno-de-Guigues hydrogen discovery in Quebec. The exploration area covers Armstrong, Brethour, Whitewood Grove, and Tomstown in Northern Ontario. Additionally, DiagnaMed has engaged Independent Trading Group (ITG) for market-making services at C$5,000 per month to enhance share liquidity on the CSE.

Positive

• Company is applying a previously successful geological model from Quebec's St-Bruno-de-Guigues hydrogen discovery
• Strategic claim selection in areas with favorable geological characteristics for hydrogen and helium generation
• Engagement of ITG for market-making services could improve stock liquidity

Negative

• Early-stage exploration with no guaranteed success
• Monthly costs for market-making services add to operational expenses

INRS Begins Data Review Ahead of Upcoming Soil Gas Sampling Program

Toronto, Ontario--(Newsfile Corp. - June 17, 2025) - DiagnaMed Holdings Corp. (CSE: DMED) (OTCQB: DGNMF) ("DiagnaMed" or the "Company"), a Canadian technology innovator specializing in advanced hydrogen extraction technologies, is pleased to announce the advancement of its program in Ontario's Timiskaming district. In preparation for the upcoming soil gas sampling campaign, DiagnaMed, in collaboration with the Institut National de la Recherche Scientifique (INRS) and Quebec Innovative Materials Corp. (CSE: QIMC) (OTC: QIMCF) (FSE: 7FJ) ("QIMC"), has initiated a comprehensive review and interpretation of all available geological data. This review will identify high-priority target zones across DiagnaMed's strategically acquired claims.

This initiative follows the successful application of the same model previously deployed by the INRS and QIMC in the St-Bruno-de-Guigues hydrogen discovery on the Quebec side of the Timiskaming graben. By leveraging similar geological structures and fault systems, the Company aims to replicate that success and validate this proprietary approach on the Ontario side.

DiagnaMed's claim selection strategy is based on a geological framework favorable for natural hydrogen (H₂) and helium (He) generation. Areas were carefully selected, prioritizing:

• Precambrian bedrock rich in potassic and radiogenic rocks,

• Paleozoic sedimentary formations with reservoir and caprock potential,

• Active rift and graben systems, notably the Ottawa-Bonnechere and Lake Timiskaming grabens,

• Normal fault systems conducive to gas migration and trapping,

• Presence of ultramafic rocks, iron formations, and potassic granitoids—favorable sources for H₂ and He.

These structures are supported by documented continental intraplate seismicity from the Geological Survey of Canada, indicating tectonic activity that may enhance subsurface gas circulation.

The targeted exploration area encompasses Armstrong, Brethour, Whitewood Grove, and Tomstown in Northern Ontario, where DiagnaMed holds extensive exploration permits.

John Karagiannidis, President and CEO of DiagnaMed, commented:

"Our work in Ontario builds directly upon the geological successes we've achieved in Quebec. With our model already validated at St-Bruno-de-Guigues, we are confident this next phase will demonstrate the vast untapped potential for natural hydrogen and helium across the Timiskaming corridor. INRS's technical expertise and our proprietary extraction technology will be instrumental in identifying and targeting the most promising structures."
