Solstice Minerals (ASX:SLS) has recommenced Phase 1 reverse circulation drilling at its 100%-owned Nanadie Copper-Gold Project, located approximately 100km northwest of Sandstone in Western Australia's Murchison Goldfields, following a short Christmas/New Year break.
The program has been expanded from 5,000m to 6,300m after strong geological observations from the first 13 holes drilled in late 2025, with the aim of extending and increasing drilling density within the current 40.4 Mt inferred mineral resource estimate, which contains 162,000 t of copper and 130,000 oz of gold.
The deposit, hosted in a shallow, mafic intrusive package, remains open laterally and at depth, with historical intercepts demonstrating both scale and commercial grades, including 107.8 m at 0.91% Cu and 0.24 g/t Au.
Geological logging to date confirms a widely mineralised mafic intrusive system flanked by amphibolite and younger granitoid rocks, supporting further exploration of both near-mine step-out targets and deeper extensions.
Solstice expects first assay results from 2025 drill samples by mid-late January, with the expanded program set to test both the existing MRE footprint and broader regional targets.
CEO Nick Castleden said the results so far reinforce the potential to materially increase the Nanadie MRE, highlighting the strategic significance of copper amid a positive long-term supply-demand outlook.
