North Stawell Minerals (ASX:NSM) has commenced a 2,000–2,500-metre air core drilling program at its Caledonia and Darlington projects in Victoria.
The campaign is being executed by AMWD, a Victorian-based drilling specialist with extensive operational experience within the Stawell Zone.
The move marks a significant expansion of NSM’s exploration footprint as the company moves into its 2026 work program.
At the Darlington prospect, this new phase of drilling follows diamond drilling campaigns conducted in February and November 2025.
The previous efforts identified a shallow, high-grade gold zone running parallel to the historic Darlington Mine trend.
Previous intercepts include 2.3m at 29.3 g/t Au from 108.2m (including 0.8m at 82.0 g/t Au) and 0.5m at 6.10 g/t Au from 283.35m.
The Darlington target shares structural similarities with the historic Mariners Lodes at Stawell, located just 6km to the south, which historically produced grades between 28 and 30 g/t Au.
Drilling at Caledonia will build upon a surface geochemical survey completed in February.
That survey identified anomalous gold consistent with the broader 3.6km Darlington-Caledonia mineralised trend.
Both prospects remain open in all directions, and the current program features step-out drilling designed to test along-strike extensions.
