Primary Hydrogen Corp. announced the commencement of its H₂ field sampling program at the Mary’s Harbour and Point Rosie projects in Labrador and Newfoundland respectively (collectively, the Atlantic Canada H₂ Projects). Field sampling activities will be conducted by Eastern Geo Services under the supervision of Peter Lauder, Vice President of Exploration, utilizing specialized sampling methodologies designed and tested by INRS to minimize artificially generated H₂. This field program, representing the second phase (Phase 2) of the Company’s multi-phase exploration strategy, is anticipated to cover approximately 8,550 hectares and to be completed over the next four weeks.

“As we advance our phased exploration strategy, this Phase 2 sampling program is critical for identifying potential natural H₂ accumulations, refining priority exploration targets, and guiding subsequent phases of exploration toward delineating potential natural H₂ resources,” stated Peter Lauder, Vice President of Exploration for Primary Hydrogen. “Leveraging robust methodologies and immediate real-time field analysis, we anticipate efficiently delineating promising targets and increasing the effectiveness of future exploration and evaluation activities.”

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, helping to detect anomalies indicative of potential subsurface H₂ accumulations. This integrated approach is specifically aimed at efficiently identifying the presence of any natural H₂ at surface levels, while simultaneously refining the company’s geological understanding of potential H₂ 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 H₂. Collected data will directly inform subsequent exploration phases, increasing confidence in the identification and evaluation of prospective natural H₂ targets. Upon completion of this Phase 2 program, results will be analyzed, and the Company anticipates providing further updates and details as data becomes available.

The Company is also pleased to announce the extension of its strategic marketing agreement (the services agreement) with Euro Digital Media Ltd. Under the terms of the Services Agreement, Euro Digital will create campaigns, ad groups, text ads, display ads, perform detailed keyword research, setup and manage remarketing campaigns, optimize keyword options, coordinate online advertisers and marketers corresponding to online marketing targets, create landing pages for ad campaigns and generally bring attention to the business of the company.
