Argyle Resources Initiates Drill Permit Application For Clay Howells Rare Earth Element Project In Ontario

(MENAFN- Newsfile Corp) Calgary, Alberta--(Newsfile Corp. - June 6, 2025) - Argyle Resources Corp. (CSE: ARGL) (OTCQB: ARLYF) (FSE: ME0) ("Argyle" or the "Company") is pleased to announce that it will begin the permitting process for a new drilling campaign at its Clay Howells Rare Earth Element (REE) Project, located in northwestern Ontario.

The Company is preparing to launch a 2000-meter diamond drill program, contingent on receipt of the necessary exploration permits from the Ontario Ministry of Mines. The planned program is designed to twin six historic drill holes that were completed on the property during previous exploration campaigns in 2010 and 2011.

This upcoming drill program is a key step in the Company's plan to update the project's geological model and publish a new National Instrument 43-101 ("NI 43-101") compliant technical report. The updated report will provide a modernized assessment of the Clay Howells REE mineralization based on current disclosure standards and support the Company's ongoing project development strategy.

"The Clay Howells Project represents a significant opportunity for domestic rare earth element exploration in Ontario," said Jeffrey Stevens CEO of Argyle Resources. "By twinning the historic drill holes and validating past results under modern standards, we aim to de-risk the project and position Argyle for future resource delineation and strategic partnerships."

The six historical drill holes returned encouraging results that outlined REE mineralization over significant widths. The new drilling will allow for the collection of fresh core samples to validate prior assay data, improve confidence in geological interpretations, and guide future exploration activities across the broader Clay Howells property.
