Primary Hydrogen Begins Phase 2 Field Sampling in Northern Ontario to Advance Natural Hydrogen Exploration
Primary Hydrogen Corp. (TSXV: HDRO) has officially launched Phase 2 field sampling at its Blakelock and Hopkins projects in Northern Ontario, in partnership with the Institut national de la recherche scientifique (INRS).
This program, covering over 9,100 hectares, focuses on validating surface hydrogen anomalies and prioritizing prospective targets for follow-up exploration. The work will specifically examine major northeast-trending faults, the Clay Howels Alkali Complex, and several forest ring structures believed to act as pathways for natural hydrogen migration.
The fieldwork integrates portable gas detectors for real-time in-field measurements with traditional geological techniques such as soil sampling and mapping. The results will directly shape future exploration phases and guide the Company’s strategy toward identifying and delineating potential hydrogen resources.
“This next phase is critical for refining our targets and advancing our understanding of natural hydrogen systems in Northern Ontario,” said Peter Lauder, VP Exploration at Primary Hydrogen.

Calgary, Alberta – July 22, 2025 – Primary Hydrogen Corp. (TSXV: HDRO, FRA: 83W0, OTCQB: HNATF) ("Primary" or the "Company") is pleased to announce it has initiated the field sampling program at its projects in Northern Ontario, namely the Blakelock and Hopkins projects. The field sampling program will be conducted by a team comprised of the Company (Peter Lauder, VP Exploration) in conjunction with representatives from the Institut national de la recherche scientifique (“INRS”), under the previously announced partnership and research agreement (see April 14, 2025 Press Release).
“This next phase of exploration is designed to validate surface hydrogen anomalies and prioritize the most prospective targets for follow-up,” said Peter Lauder, Vice President of Exploration at Primary Hydrogen. “By integrating real-time field analysis with proven geological techniques, we aim to advance our understanding of natural hydrogen systems in Northern Ontario and accelerate our path toward delineating a potential resource.”
This second phase of the multi-stage program will collect soil and soil gas samples across approximately 9,127 hectares and is expected to be completed by the end of July. The sampling will target major northeast trending faults and the Clay Howels Alkali Complex formations in addition to systematically testing several forest rings, or subcircular depressions, that represent potential pathways for naturally occurring gasses such as hydrogen.The exploration program integrates portable gas detectors, providing immediate in-field measurements, with conventional geological exploration techniques, including soil sampling, prospecting, and geological mapping. Soil gas sampling involves the collection and analysis of gases present in soil pores near the surface, to identify anomalies that may indicate the presence of subsurface hydrogen accumulations. This integrated approach is specifically aimed at efficiently identifying the presence of any natural hydrogen at surface levels, while simultaneously refining the Company’s geological understanding of potential hydrogen generation sources, migration pathways, and accumulation zones.
Primary Hydrogen’s sampling methodology and procedures have been collaboratively developed with INRS, leveraging laboratory-verified techniques to ensure consistent, reliable results and minimize artificially generated hydrogen. Collected data will directly inform subsequent exploration phases, increasing confidence in the identification and evaluation of prospective natural hydrogen targets. Upon completion of Phase 2, collected data will be analyzed, and the Company expects to provide detailed results and exploration updates as they become available.
