Colchester East Natural Hydrogen Project

DiagnaMed has added the newly announced Colchester East Natural Hydrogen Project in Nova Scotia to its exploration portfolio, establishing a strategic foothold in one of North America’s fastest-emerging natural hydrogen corridors. The region has attracted significant industry interest following early indications of hydrogen potential, making this acquisition an important expansion of the Company’s growing land position.

The project lies within a structural regime characterized by deep-seated fault systems, fractured basement contacts, and intact sedimentary caprock—geological attributes increasingly linked to the generation and entrapment of natural (“white”) hydrogen. Recent academic and industry studies have highlighted the Maritimes Basin and its surrounding structures as highly prospective due to their tectonic evolution, evaporite sequences, and localized heat-flow patterns.

The area surrounding Colchester East has reported measurable hydrogen concentrations through neighbouring exploration efforts, adding to evidence that Eastern Canada may host the country’s earliest natural hydrogen prospects. The clustering of new claims by QIMC, Koloma, and Rio Tinto in adjacent blocks reflects intensifying industry focus on this district and reinforces the strategic value of securing early land positions within it.

Initial assessments indicate that the Colchester East licenses exhibit several favourable subsurface attributes, including fault-linked migration pathways, protective caprock seals, and stratigraphic horizons historically associated with fluid movement and gas presence. These conditions create a strong technical foundation for modern exploration techniques such as soil-gas surveys, microseepage analysis, spectral imaging, and targeted geophysical programs.

As the broader region continues to develop into a recognized natural hydrogen exploration district, early entrants are positioned to benefit from expanding datasets, collaborative research, and advancements in detection and extraction technologies. For DiagnaMed, the acquisition of Colchester East strengthens its multi-jurisdictional strategy, complements its Ontario assets, and advances the Company’s objective of building a diversified and scalable natural hydrogen portfolio.

Ontario – Timiskaming Exploration Program

DiagnaMed has secured a strategic land position in the Timiskaming District of northern Ontario, within the Témiscamingue–Timiskaming Graben. This corridor, known for its deep fault structures and iron-rich Archean rocks, provides ideal conditions for natural (“white”) hydrogen generation and migration.

The site will serve as a demonstration area for validating DiagnaMed’s proprietary geological survey methods and TerraVent Environmental’s electromagnetic stimulation technology, designed to release hydrogen from subsurface formations.

Early exploration work, including soil-gas sampling, has confirmed hydrogen concentrations exceeding 2,000 ppm, supporting the region’s strong geologic potential. The project builds on DiagnaMed’s success in Québec and advances the company’s broader vision to develop Canada’s Natural Hydrogen Corridor.

Terravent’s Hydrogen Extraction Technology

Proprietary Natural Hydrogen Extraction Process

Terravent has developed a breakthrough method for directly extracting natural hydrogen (also known as white hydrogen) from subsurface geological formations. This proprietary process is designed for high selectivity and efficiency, capturing hydrogen at the source with minimal energy input and no chemical additives.

Zero Carbon Emissions, Minimal Environmental Footprint
Unlike traditional hydrogen production methods (such as SMR or electrolysis), Terravent’s approach does not emit carbon dioxide or require water electrolysis. The extraction process operates without combustion, minimizes surface disturbance, and requires no large-scale infrastructure, making it uniquely sustainable and environmentally friendly.

Robust Economic Viability
Terravent’s method offers a low-cost path to hydrogen production by eliminating the need for expensive feedstocks and energy-intensive processing. The scalable nature of the extraction units allows for modular deployment, reducing up-front capital requirements while enabling local, decentralized energy solutions.

Leveraging QIMC’s Expertise in Natural Hydrogen Exploration
By partnering with Quebec Innovative Materials Corp (QIMC), a pioneer in geologic hydrogen detection, Terravent benefits from advanced subsurface mapping, soil gas analysis, and structural geology targeting. This collaboration accelerates site identification, reduces exploration risk, and improves the success rate of hydrogen well development.

Current Projects and Collaborations

Ontario – Timiskaming Exploration Program

DiagnaMed is advancing its Ontario Natural Hydrogen & Helium Exploration Program in the Timiskaming District, located within the Témiscamingue–Timiskaming Graben along the Ontario–Québec border.

This region’s Archean iron-rich rocks and deep fault structures create ideal conditions for natural hydrogen generation and trapping. The program serves as a demonstration zone for DiagnaMed’s proprietary soil-gas surveying methods and TerraVent Environmental’s electromagnetic stimulation technology, developed for clean subsurface hydrogen extraction.

In collaboration with Québec Innovative Materials Corp. (QIMC), early field results confirmed a widespread natural hydrogen system in the area, with 456 soil-gas samples collected—209 exceeding 500 ppm H₂ and multiple readings above 2,000 ppm.

Québec – QIMC & Témiscamingue First Nation Partnership

A cornerstone partnership with QIMC has produced significant results at the St-Bruno-de-Guigues site, where hydrogen concentrations reached over 21,000 ppm. In October 2025, DiagnaMed, QIMC, and the Témiscamingue First Nation (TFN) signed a Memorandum of Understanding to advance exploration along the Ontario–Québec corridor, emphasizing Indigenous engagement, environmental stewardship, and regional economic participation.

This partnership validates DiagnaMed’s integrated geological model and establishes a collaborative framework for commercial-scale hydrogen development across northern Ontario and western Québec.

Technology & Infrastructure Collaboration

DiagnaMed continues to collaborate with TerraVent Environmental Inc. on deploying its patented Heatwave® electromagnetic extraction tools, originally developed with Texas Tech University, to release hydrogen directly from the subsurface.

The company is also engaging with energy operators and government stakeholders to evaluate opportunities for repurposing inactive oil and gas wells for clean-hydrogen extraction supporting infrastructure reuse and aligning with national net-zero objectives.

Validated Results

The St-Bruno and Timiskaming sites together confirm the effectiveness of DiagnaMed’s full-cycle discovery and extraction model. These results demonstrate the technical viability and scalability of the company’s approach to producing low-cost, near-zero-emission hydrogen and advancing the foundation for Canada’s Natural Hydrogen Corridor.
