Solstice Minerals’ Nanadie copper–gold: scale-up and resource lens for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Solstice Minerals is expanding the scale of its Nanadie copper–gold project in Western Australia after completing 10,623m of drilling in the quarter, comprising 15 diamond tails and 26 reverse circulation holes. Assays from these programmes show mineralisation now extending over at least several kilometres of strike, prompting the company to target a larger, district-scale copper system rather than a small stand-alone resource. For geologists and mine planners, the step-up in drilling density and depth suggests a shift towards defining a substantial sulphide resource with longer-term underground potential.
Technical Brief
- Quarterly drilling comprised 15 diamond tails plus 26 RC holes, totalling 10,623m of new data.
Our Take
The earlier Nanadie drilling reports in August 2026, with long copper–gold intercepts extending beyond the existing resource envelope, suggest Solstice Minerals is likely testing whether the system can support a larger, lower-grade open pit rather than just chasing discrete high-grade shoots.
With 15 diamond tails and 26 RC holes reported in a single quarter at Nanadie, Solstice’s metreage is now at the upper end of what our database shows for single-asset copper–gold juniors in Western Australia, signalling a deliberate push to fast-track resource growth ahead of any scoping-level studies.
Copper–gold projects in Western Australia feature prominently in our 1251 Mining stories, and Nanadie’s near-surface intercepts place it in the same exploration ‘bulk-tonnage’ bucket as several other WA copper plays that are being evaluated for future hub-and-spoke processing or toll-treatment options.
