ARGYLE RESOURCES COMPLETES LAC COMPORTÉ SILICA PROJECT 2,287 METRES DRILLING CAMPAIGN

Argyle Resources Corp. has provided an update on its recently completed diamond drilling campaign at the Lac Comporte silica project, located in the Bas-Saint-Laurent region of Quebec, Canada.

The 2025 program was executed efficiently over 23 days in December, averaging 104 metres per day despite challenging winter weather and logistical constraints for a total of 2,287 m. The campaign successfully targeted two west-northwest-trending quartzitic units previously identified as high-priority targets with surface grades reaching up to 98 per cent SiO2. All core samples are being prepared for submission to the laboratory, with a full suite of assay results expected in early Q1 2026.

The campaign successfully targeted two west-northwest-trending, kilometre-scale quartzitic units identified during the 2025 summer field program. These units exhibit metre-scale thicknesses and surface grades reaching up to 98 per cent SiO2. Preliminary visual inspections of the NQ-sized core indicate significant quartzitic intervals; however, these visual estimates are subject to laboratory verification.

Jeffrey Stevens, chief executive officer of Argyle Resources, commented: "We are extremely pleased with the successful completion of our 2025 drilling campaign at the Lac Comporte silica project. We look forward to sharing these results and continuing to build value for our shareholders and stakeholders in Quebec's Bas-Saint-Laurent region."
