(MENAFN- Newsfile Corp) Calgary, Alberta--(Newsfile Corp. - October 28, 2025) - Argyle Resources Corp. (CSE: ARGL) (OTCQB: ARLYF) (FSE: ME0) ("Argyle" or the "Company") is pleased to provide an update on its recently completed diamond-drilling campaign at the Clay Howells Rare Earth Element (REE) Project, located in northwestern Ontario.

End-of-Run Summary

The 2025 drilling campaign for the Clay Howells targets was executed across 20 days, completing 7 diamond-drill holes, totaling 2,000 metres. The drilling utilized a BTW-core rig, achieving an average of 100 metres per day across the 20 days of operation. To minimize environmental impact, all drill moves and personnel transport were supported by Helicopters. Results from the campaign have been sent to the lab, with the first batch of results expected back in 3-4 weeks and the second batch in 5-6 weeks.

Operational Overview

The drilling campaign targeted magnetic highs, which were interpreted to target REE-enriched magnetite-bearing carbonatite. Despite experiencing logistical challenges, such as variable weather and a limited water supply at some drill sites, the campaign maintained excellent performance and safety standards throughout.

CEO Comment

Jeffrey Stevens, CEO of Argyle Resources, stated:

"Argyle Resources is pleased to report the completion of a successful 2,000 metre drill campaign. We remain optimistic on the geological potential of the Clay Howells property and look forward to reviewing the results and determining a path forward in the region"
