Primary Hydrogen Commences Field Sampling Program at Dove Creek

CALGARY, AB / ACCESS Newswire / June 24, 2025 /Primary Hydrogen Corp. (TSXV:HDRO)(FRA:83W0)(OTCQB:HNATF) ( "Primary " or the "Company ") is pleased to announce the commencement of its field sampling program at the Dove Creek project in Colorado, USA. Field sampling will be conducted by Lonewolf Energy, Inc. under the supervision of Peter Lauder, VP of Exploration, utilizing techniques designed and tested by the INRS to minimize artificially produced hydrogen. The program, representing the second phase (Phase 2) of a multi-phase program, is anticipated to collect soil gas samples over an area of 740 acres and be completed within the next two weeks.

"This second phase of our exploration program is expected to gather critical information that will aid in the development of our exploration model and guide future exploration endeavours " commented Peter Lauder, VP Exploration of Primary Hydrogen. "Employing portable gas detectors provides for real-time, in-field to rapidly identify potential subsurface anomalies and accelerate target definition - providing a critical foundation to advance Dove Creek 's resource potential through focused future exploration. "

Primary 's sampling methodology and process has been developed in collaboration with the INRS, utilizing laboratory-verified techniques to minimize artificial hydrogen generation during collection and ensuring consistent and dependable results. The data will inform subsequent exploration phases, increasing confidence in identifying the source of anomalous hydrogen readings.

Dove Creek Project, Colorado

Located in southwestern Colorado near the Colorado-Utah border, the Dove Creek project lies within the Paradox Basin, proximal to the San Juan Basin to the south and the Uinta-Piceance Basin to the north. The project 's prospectivity is driven by the potential for natural hydrogen generation through radiolysis of uranium-rich basement rocks. Deep-seated fault systems in the region serve as migration pathways for hydrogen, which may accumulate in structural or stratigraphic traps. Geophysical data highlight strong gravity anomalies aligned with fault structures and magnetic anomalies tied to deep crustal features. The presence of helium wells in the area further supports active subsurface gas migration, enhancing the project 's hydrogen potential.
