Primary Hydrogen Outlines Initial Exploration Program for Wicheeda North

CALGARY, AB | May 30, 2025 / Primary Hydrogen Corp. (TSXV:HDRO)(FRA:83W0)(OTCQB:HNATF) ("Primary" or the "Company") is pleased to outline an initial exploration program for the Wicheeda North project (the "Project") in British Columbia. The exploration program (the "Program") will be focused on the evaluation of natural hydrogen potential in addition to the potential to host significant rare earth element (REE) mineralization. The first phase of the program will include soil and soil-gas sampling, in conjunction with property-wide geophysics, both of which leverage and expand on prior exploration programs. Specifically, the Program will focus on extending soil sampling efforts within the remaining target zones identified from magnetic and historical geochemical anomalies, and conducting airborne electromagnetic (EM) survey over the southern portion of the properties which was not previously done and coincides with the southern edges and potential future expansion of historical prospect sampling.

The Project has the potential to host REE mineralization as it occurs within a favorable geological belt known to contain carbonatite-hosted REE mineralization such as the Main Zone on the Wicheeda project located within 5 kilometres to the southeast. The Wicheeda Rare Earths Project, which is owned by Defense Metals Corp., adjoins the Project to the southwest and is host to a NI 43-101[1] M&I Resource of 29.3Mt grading 2.27% TREO (total rare earth oxide) plus Inferred Resource of 5.7 Mt grading 1.4% TREO.

"Anomalous cesium (Ce) in soil samples shows a spatial distribution consistent with the Wicheeda REE deposit, located 5 km along strike. This alignment, combined with a well-defined circular magnetic anomaly, underscores strong geological potential. Newly identified soil targets further enhance the project's exploration upside," said Peter Lauder, VP Exploration at Primary Hydrogen Corp.

The Wicheeda North project is comprised of nine contiguous mineral claims covering an area of 2,138 hectares (21.1 km2) in the northern Cariboo Mining Division. The Project is located within the Rocky Mountain Trench, a significant regional scale geological feature, which is recognized to host carbonatite intrusions which is the host for REE mineralization. Historical geochemical and geophysical studies have identified seven targets based on identification of sub-circular to elliptical features within magnetic anomalies and coincident elevated levels of cesium (Ce) in rock and soil samples (where available). Two of the more prominent targets[2], Grid A and Grid D in Figure 1, highlighted by anomalous values as determined using the 99th percentile of REE's and is indicative of a potential REE source. These two target areas will be the initial focus of follow-up and expansionary soil sampling and geochemical analysis to better define the extent and trend of mineralization. Concurrent geophysical surveys are planned to extend coverage to the southwest portion of the Project.
