ARGYLE RESOURCES TERMINATES OPTION ON CLAY HOWELLS RARE EARTH PROPERTY; REAFFIRMS FOCUS ON MCKAY HILL SILVER AND QUEBEC SILICA ASSETS

Argyle Resources Corp. has elected to terminate its option agreement on the Clay Howells rare-earth element (REE) property, comprising 10 contiguous mining claims (approximately 160 hectares) located in Northwestern Ontario.

The decision follows the company's 2025 exploration program on the property, which included compilation and review of historical data, surface field evaluations, and a 2,000-metre, seven-hole BTW-core diamond drilling program designed to validate previously reported REE mineralization. The 20-day campaign, executed in October, 2025, was helicopter supported and targeted magnetic highs interpreted as REE-enriched magnetite-bearing carbonatite. Assay results from the program were reviewed by the company's qualified person. The results did not demonstrate REE grades or geological continuity sufficient to justify further expenditures under the option agreement.

Jeffrey Stevens, chief executive officer of Argyle Resources, commented:

"We completed a disciplined drill test of the Clay Howells targets, and the results provided useful clarity. Based on the data, we did not see a strong basis for continued work at this time, and we are shifting our technical and financial efforts toward projects with more established potential -- principally the McKay Hill silver project in the Yukon."

The company has provided notice to the vendors that it will not proceed with the remaining option payments or work commitments. The property -- which was held subject to a 1.5-per-cent net smelter returns royalty under the original agreement -- will revert to the underlying owners in accordance with the terms of the agreement. No further obligations or contingent liabilities related to the Clay Howells property remain.

Argyle will continue to focus its technical and financial resources on its core portfolio.
