Primary Hydrogen Corp. announced the commencement of a geophysical survey at its Wicheeda North Rare Earth Element (REE) Project (the project) in British Columbia.

The Company has engaged Geotech Ltd. to conduct an infill airborne Versatile Time-Domain Electromagnetic (VTEM) and magnetic survey, totaling approximately 401 line-kilometers, completing coverage of the property and covering 25 square kilometers. The survey data will be integrated with historical geophysical information to generate a comprehensive property-wide interpretation. The focus of the program is to refine previously defined targets and soil anomalies, and to identify additional targets to guide future trenching and drill planning. A Notice of Work for a multi-year exploration trenching and drilling program has been submitted and is anticipated later this year.

“This property-wide geophysical survey will allow us to evaluate previously unexplored areas and generate a refined set of exploration targets,” stated Benjamin Asuncion, CEO of Primary Hydrogen. “The results will help prioritize areas for future trenching and drilling, supporting our broader objective of delineating REE mineralization at Wicheeda North.”

The 2025 exploration program (the program) is designed to assess both the natural H₂ potential and REE prospectivity of the Wicheeda North Project. Phase One includes:

• Soil and soil-gas sampling
• Property-wide airborne geophysical surveying
• Follow-up geochemical analysis of key zones.

Soil sampling will be expanded across high-priority target areas defined by historical magnetic anomalies and geochemical trends. The airborne electromagnetic and magnetic survey will cover the southern portion of the property, which has not been previously surveyed and overlaps with historical prospecting targets—potentially offering expansion opportunities.

Wicheeda North is located within a geological belt prospective for carbonatite-related REE mineralization, similar to the adjacent Wicheeda Rare Earths Project, owned by Defense Metals Corp., approximately 5 km to the southeast. That project hosts a NI 43-101 compliant resource of 29.3 million tons grading 2.27% Total Rare Earth Oxide (TREO) (measured and indicated), and an inferred resource of 5.7 million tons grading 1.4% TREO.

The Wicheeda North Project comprises nine contiguous mineral claims totaling 2,138 hectares (21.1 km²) in the northern Cariboo Mining Division, within the Rocky Mountain Trench—a structural corridor known to host carbonatite intrusions. Historical work identified seven geophysical and geochemical targets, including sub-circular to elliptical magnetic anomalies and elevated REE concentrations in soil and rock.

Two key zones, known as Grid A and Grid D, were delineated using the 99th percentile of REE concentrations and are considered high-priority exploration targets. These zones will be the focus of expanded soil sampling and detailed geochemical follow-up. Concurrently, the VTEM and magnetic surveys will extend coverage into the southwestern portion of the property.
