(MENAFN- Newsfile Corp) Calgary, Alberta--(Newsfile Corp. - November 18, 2025) - Argyle Resources Corp. (CSE: ARGL) (OTCQB: ARLYF) (FSE: ME0) ("Argyle" or the "Company") is pleased to announce that following completion of the permitting process, the company is now in position to start the drilling program at Lac Comporté, Silica Project, located in the Bas-Saint-Laurent region of Quebec, Canada.

The drilling campaign will comprise 3,000 metres of NQ-sized core, specifically targeting the most encouraging results from the Company's successful summer field program. This summer effort, which involved comprehensive mapping and prospecting, defined a kilometric horizon of quartzite. Four samples from this horizon returned assays of up to 98% SiO2, with a high-grade result of 98.52% SiO2 (Sample E715925).

Jeff Stevens, CEO of Argyle Resources Corp., commented: "Advancing to the drilling stage at Lac Comporté marks a pivotal moment for Argyle. Our summer program reinforced the project's potential, and we're excited to begin testing these targets with a focused 3,000-metre campaign. This milestone reflects our commitment to disciplined exploration and unlocking value in Quebec's emerging silica corridor."
