ARGYLE RESOURCES CORP. PROVIDES DRILLING UPDATE FOR CLAY HOWELLS REE PROJECT

Argyle Resources Corp. has provided an update on its continuing diamond drilling program at the Clay Howells rare-earth element (REE) project, located in Northwestern Ontario.

The campaign has completed four holes, and drilling is now under way on the fifth. A significant highlight is the discovery of a 5.9-metre interval of magnetite-layered carbonatite in drill hole CH-25-04. This finding is particularly promising as preliminary analysis confirms the presence of a high-grade rare-earth element (REE) system, providing strong validation for the property's potential. The company is actively following up on this success by drilling the current hole, CH-25-05, in the same magnetic anomaly area.

Diamond drilling progress

During the past week, from Sept. 21 to Sept. 29, Argyle made significant progress in its drilling program. A total of 1231 metres were drilled, averaging 102.6 metres per day. Drilling is advancing as planned, with hole CH-25-05 (2025-AR-001) currently at 267 metres of a planned 300 metres. This steady progress reassures the company that it is on track with its drilling schedule. Drilling is expected to be completed shortly, after which the next planned hole, 2025-AR-006-b, will commence.

Recap of drilling highlights

Significant mineralization in hole CH-25-04: A notable intersection of magnetite-layered carbonatite was encountered from 165.25 to 171.15 metres (a 5.9-metre interval).

Drilling at Clay Howells this past week showed encouraging signs. In hole CH-25-04, the team intersected a magnetite-rich carbonatite zone between 165 and 171 metres, a rock type known to host rare-earth elements. Portable XRF readings confirmed the presence of cerium, lanthanum, neodymium and praseodymium, making this one of the most promising intervals encountered so far in the program. While hole CH-25-05 is under way and has reached 267 metres of its planned 300-metre depth, findings have led to mainly pink and grey syenite. While no carbonatite has been hit yet in this hole, its proximity to CH-25-04 means it remains a high-priority target.

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

"Our drilling program at Clay Howells is progressing well, with early results providing valuable insight into the property's geology. The discovery of magnetite-layered carbonatite in CH-25-04 is a key development that supports our geological model and will help refine future targeting across the project."
