PRIMARY HYDROGEN IDENTIFIES TWO HIGH-PRIORITY REE ANOMALY CLUSTERS FROM GEOPHYSICAL AND SOIL SAMPLING SURVEY AT WICHEEDA NORTH PROJECT

Primary Hydrogen Corp. has identified two significant rare earth element (REE) anomaly clusters following completion of comprehensive geophysical and soil sampling surveys at its Wicheeda North REE project in British Columbia.

Key highlights:

• Completed 401-line-kilometre airborne VTEM (versatile time-domain electromagnetic) and magnetic survey covering 25 square kilometres;
• Collected 533 new soil samples, bringing total property-wide samples to 1,234;
• Identified two high-priority REE anomaly clusters in Grid A-South and Grid D-South areas;
• Applied for drilling and trenching permits to advance exploration program;
• Project located five kilometres from Defense Metals Corp.'s Wicheeda deposit (29.3 million tonnes at 2.27 per cent TREO (total rare earth oxide)).

Survey results and anomaly identification

Geotech Ltd. successfully completed an airborne VTEM Plus and magnetic survey, covering 401 line kilometres over 25 square kilometres. The new data are being integrated with historical data sets to create a seamless property-wide survey. Advanced inversion techniques, including MVI3D and structural complexity analysis, will provide comprehensive insights into subsurface geology and potential REE mineralization.

The company's 2025 soil sampling program, conducted by Tripoint Geoservices, collected 533 samples, bringing the total property-wide sample count to 1,234. Sample results were normalized with previous surveys to account for analytical method variations, enabling comprehensive data comparison.

Two distinct anomaly clusters representing the top 5 per cent of REE values were identified:

• Grid A-South -- located in the northeastern region of the claim blocks;
• Grid D-South -- located in the eastern region of the claim blocks.

Both anomalous areas are situated near the Wichcika River. While certain anomalous samples may originate from river sediment transport, samples collected at higher elevations above the flood plain likely indicate proximal bedrock sources, warranting further investigation.

Geological interpretation and next steps

Target 4, identified in the 2023 Power One National Instrument 43-101 technical report, may account for the Grid A-South anomalous samples and will be a focus of future exploration. The Grid D-South anomaly represents a newly recognized zone of interest without any prior identified targets and is currently under active investigation.

Background REE levels across the Wicheeda North property are lower than those observed at the adjacent Wicheeda deposit, potentially indicating greater overburden depth.

The company has applied for drilling and trenching permits with the British Columbia Ministry of Energy, Mines and Low Carbon Innovation. Approval is anticipated in Q1 2026.

Planned exploration activities include:

• Additional soil sampling to delineate and expand anomalous areas;
• Overburden depth survey to assess trenching feasibility;
• Multiphase drill program targeting anomaly sources if trenching proves unfeasible;
• Expanded sampling at Zone B, identified as a prospective untested area.

"The programs were conducted in accordance with the recommendations specified in our recently updated NI 43-101 technical report," stated Benjamin Asuncion, chief executive officer of Primary Hydrogen. "The successful completion of these surveys and identification of high-priority anomalies will facilitate targeted trenching and drilling programs, advancing our goal to delineate REE mineralization at Wicheeda North. The proximity to Defense Metals' advanced Wicheeda deposit and our position within the same geological belt reinforces the exploration potential of our property."

About the Wicheeda North REE project

The Wicheeda North project comprises nine contiguous mineral claims totalling 2,138 hectares (21.1 square kilometres) in the northern Cariboo mining division in British Columbia. The property is located within the Rocky Mountain trench, a structural corridor known to host carbonatite intrusions associated with REE mineralization.

The project is situated approximately five kilometres northwest of Defense Metals Corp.'s Wicheeda rare earth element deposit, which hosts an NI 43-101-compliant measured and indicated resource of 29.3 million tonnes grading 2.27 per cent TREO and an inferred resource of 5.7 million tonnes grading 1.40 per cent TREO.

Historical exploration at Wicheeda North identified seven geophysical and geochemical targets, including subcircular to elliptical magnetic anomalies and elevated REE concentrations in soil and rock samples. The exploration strategy of the property relies on the latest interpretation of the carbonatite-related REE mineralisation and geochemical signatures of Defense Metals' Wicheeda REE deposit.
