PRIMARY HYDROGEN COMMENCES PHASE 2 FIELD EXPLORATION AT HOPKINS PROJECT

Primary Hydrogen Corp. (TSXV:HDRO)(FRA:83W0)(OTCQB:HNATF) ("Primary" or the "Company") is pleased to announce the commencement of Phase 2 field exploration at its Hopkins Project in Ontario. The Company has engaged Norda Stelo to conduct a focused sampling program comprising approximately 265 soil and soil-gas samples targeting both natural hydrogen and potential rare earth element (REE) mineralization.

The fieldwork is expected to be completed within one to two weeks, with analytical results from gas readings and chemical assays anticipated approximately six weeks thereafter.

"This marks our second exploration campaign at Hopkins and is designed to advance our understanding of both natural hydrogen potential and REE prospectivity," said Peter Lauder, VP Exploration at Primary Hydrogen. "In addition to expanding our earlier soil gas sampling program, this phase will assess the rare earth potential along the Clay-Howells alkali carbonatite intrusive, which is known to host REE, thorium, and iron mineralization^[1]."
