Argyle completed a 2,287-metre winter drilling program at Lac Comporté, confirming high-purity silica targets; assays expected early 2026.
Argyle Resources Corp. has announced the successful completion of its most recent diamond-drilling program at the Lac Comporté Silica Project, situated in the Bas-Saint-Laurent region of Quebec, Canada. The company confirmed that the campaign met its operational and geological objectives, reinforcing the project’s potential as a high-quality silica asset and marking an important milestone in its ongoing exploration strategy.
The 2025 drilling program was carried out over a concentrated 23-day period during December, a time typically associated with harsh winter conditions in eastern Canada. Despite challenging weather, limited daylight hours, and logistical constraints common to remote winter operations, the program was executed efficiently and safely. Drilling progress averaged approximately 104 metres per day, resulting in a total of 2,287 metres of diamond drilling completed across the targeted zones. This performance highlights both effective planning and strong on-site execution by the technical team and contractors involved.
The primary objective of the campaign was to test two west-northwest (WNW) trending, kilometre-scale quartzitic units that had been identified earlier in the year as high-priority targets. These units were initially delineated during the 2025 summer field program, which included detailed geological mapping and surface sampling. Surface results from that work returned silica grades of up to 98% silicon dioxide (SiO2), suggesting the presence of exceptionally pure quartzitic material suitable for a range of industrial and advanced technology applications.
During the winter drilling program, multiple holes were designed to intersect these quartzitic units at depth in order to evaluate their thickness, continuity, and geological characteristics beyond surface exposure. Preliminary visual examination of the recovered NQ-sized drill core indicates the presence of substantial quartzitic intervals consistent with expectations from surface observations. Several metre-scale sections of visually high-purity quartzite were noted, reinforcing confidence in the geological model developed earlier in the year. However, the company emphasized that all visual interpretations remain preliminary and must be confirmed through laboratory analysis.
All drill core samples from the program are currently being processed, logged, and prepared for submission to an accredited laboratory. A comprehensive suite of analytical tests will be conducted to determine silica content and other relevant parameters. The company expects to receive full assay results in early Q1 2026, which will provide critical data for evaluating the project’s economic potential and guiding subsequent exploration or development decisions.
Commenting on the completion of the program, Jeffrey Stevens, Chief Executive Officer, expressed strong satisfaction with the outcome of the campaign. He noted that successfully completing a technically demanding winter drilling program reflects the company’s commitment to disciplined execution and value creation. He also highlighted the importance of continuing to advance the Lac Comporté Silica Project in collaboration with local stakeholders in the Bas-Saint-Laurent region.
Overall, the completion of the 2,287-metre drilling campaign represents a significant step forward in advancing the understanding of the Lac Comporté Silica Project. Pending laboratory results will play a key role in shaping the next phase of work as the company continues to evaluate the project’s potential within the broader critical and industrial minerals landscape.
