Primary Hydrogen Reports Anomalous Hydrogen Values From Phase 1 Soil Gas Sampling at Point Rosie and Mary's Harbour Properties, Newfoundland and LabradorCALGARY, AB / ACCESS Newswire / November 26, 2025 / Primary Hydrogen Corp. (TSXV:HDRO)(OTCQB:HNATF)(FRA:83W0) (the "Company" or "Primary Hydrogen") announces completion of its Phase 1 field program at the Point Rosie and Mary's Harbour properties in Newfoundland and Labrador. The soil gas sampling program returned anomalous hydrogen values over targeted fault structures, with peak readings of 531 ppm H₂ at Point Rosie and 665 ppm H₂ at Mary's Harbour.Natural hydrogen exploration relies on detecting hydrogen gas escaping from subsurface sources. Soil gas sampling measures hydrogen concentrations at the surface, with elevated readings near fault structures potentially indicating migration pathways from deeper generation zones. The results reported herein represent the first systematic hydrogen soil gas survey on these properties."Phase 1 exploration at Point Rosie and Mary's Harbour was completed successfully, with anomalous hydrogen soil gas values corresponding to deep-seated fault structures," said Peter Lauder, P.Geo., VP Exploration. "These results provide encouraging indicators for hydrogen migration pathways. The Company is currently reviewing all data to determine and plan appropriate follow-up work."The multi-phase program encompassed soil and soil gas sampling across 8,550 hectares. Targeted areas included northeast and east-southeast trending faults, and additional soil samples were collected from the sample stations. The outcomes of these programs will guide future exploration initiatives.Point RosieThe Point Rosie property is located on the Burin Peninsula on the southern coast of Newfoundland, within a region characterized by mafic intrusions and volcanic sequences. This area is known for its extensive mafic dikes and sills, which are ideal candidates for serpentinization and hydrogen production.The region contains several prominent fault zones, particularly along the contact between mafic intrusions and older basement rocks. These fault systems could serve as migration pathways for hydrogen, originating from deep crustal or mantle sources.A total of 78 soil gas stations were sampled at Point Rosie, with an emphasis placed on fault structures and geological contacts within the pr...
