York Harbour Expands Into Clean Energy Exploration Through Strategic Hydrogen Asset Acquisition

(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - September 25, 2025) - YORK HARBOUR METALS INC. (CSE: YORK) (OTC Pink: YORKF) (FSE: 5DE) (the " Company " or " York Harbour ") is pleased to announce that it has entered into a mineral property purchase agreement (the " Agreement ") with 1502757 B.C. Ltd (the " Seller "), for the acquisition of a portfolio of highly prospective hydrogen assets located in Ontario and Quebec, Canada (the " Acquisition ").

These assets position York Harbour at the forefront of the emerging "white hydrogen" exploration cycle, similar to the early days of lithium and rare earth exploration

Hydrogen: A Strategic Exploration Commodity

Natural (or "white") hydrogen is increasingly recognized as a potentially transformative resource in the global shift toward decarbonization. Unlike industrial hydrogen produced from hydrocarbons or electrolysis, natural hydrogen seeps represent a clean, renewable source formed geologically in the Earth's crust.

Key factors driving investment in hydrogen exploration include:

• Global policy support for hydrogen as a cornerstone of net-zero energy strategies.

• Industrial adoption in steelmaking, chemicals, and heavy transport.

• Exploration momentum in Canada, Australia, and the U.S., with discoveries attracting comparisons to past "white gold" cycles in lithium and rare earths.

The Hydrogen Asset Portfolio

The portfolio consists of three strategic hydrogen projects totaling over 36,000 hectares :

• Kirwan Hydrogen (Québec, 1,463 ha): 100% owned, road accessible, adjacent to Quebec Innovative Materials Corp's flagship hydrogen discovery in western Quebec.¹

• Casa Hydrogen (Québec, 5,851 ha): Option to earn 100%; hosts multiple "fairy circles" (Barren patches indicative of natural hydrogen).²

• Hearst East & West (Ontario, ~29,000 ha): 100% owned, extensive land position adjacent to Maxx Energy's hydrogen projects in Ontario, featuring widespread "fairy circles".

Blair Naughty, President and CEO of York Harbour Metals, commented:

"This acquisition provides York Harbour shareholders with exposure to an exciting new frontier in resource exploration. Natural hydrogen is being recognized as a critical clean energy commodity, with potential to rival lithium in its importance to the global energy transition. Our projects are strategically located next to some of the most active hydrogen explorers in Canada, giving us immediate relevance in this emerging sector."¹
