How Solstice’s Expanded Drilling Could Unlock Nanadie’s Copper-Gold Potential

Drilling Momentum Builds at Nanadie

Solstice Minerals Limited has announced the resumption and expansion of its reverse circulation (RC) drilling program at the Nanadie Copper-Gold Project, located northwest of Sandstone in Western Australia’s Murchison Goldfields. After a brief holiday pause, the company has increased its Phase 1 drilling plan from 5,000m to 6,300m, driven by promising geological observations from the initial 13 holes completed in late 2025.

The Nanadie Project is notable for its shallow, disseminated sulphide copper-gold system hosted within a mafic intrusive package. The current Inferred Mineral Resource Estimate (MRE) stands at 40.4 million tonnes grading 0.4% copper and 0.1 grams per tonne gold, containing approximately 162,000 tonnes of copper and 130,000 ounces of gold. This resource sits within a granted Mining Lease, positioning Nanadie as a strategic asset amid tightening global copper supply and rising demand.

Geological Insights and Exploration Potential

Geological logging of the recent drilling aligns well with historical data, confirming a broadly mineralised mafic intrusive host flanked by amphibolite and younger granitoid rocks. The mineralised system remains open in multiple lateral directions and at depth, suggesting significant upside potential. Notably, previous drilling rarely extended beyond the mineralised intrusive package, leaving room for expansion both laterally and vertically.

Historical drill intercepts have demonstrated both scale and commercial-grade mineralisation, with highlights including intercepts exceeding 100 metres at grades near 1% copper and accompanying gold values. The current program aims to increase drilling density within and below the existing resource block model, with success expected to pave the way for more systematic RC and diamond drilling campaigns.

Market Context and Financial Strength

Solstice’s CEO, Nick Castleden, emphasised the favourable market backdrop, noting copper prices have recently surpassed US$6 per pound and the metal’s long-term supply-demand fundamentals remain robust. The company’s strong cash position of approximately $14 million and zero debt provides operational flexibility to advance exploration and development activities without immediate capital constraints.

Beyond Nanadie, Solstice continues to explore its extensive gold tenure at the Yarri Project near Kalgoorlie, with ongoing drilling successes at prospects such as Bluetooth and Edjudina Range. This diversified portfolio underpins the company’s strategy to build value across multiple commodities and project stages.

Looking Ahead

All samples from the 2025 drilling campaign are currently at the laboratory, with initial assay results anticipated by mid to late January 2026. These results will be critical in assessing the potential to materially increase the Nanadie resource base. Further drilling, including step-out holes testing geophysical targets and structural extensions, is planned to continue through 2026. Metallurgical testing on archived core samples is also underway to support future development studies.

Solstice’s methodical approach, combined with a supportive copper market and a substantial existing resource, positions the Nanadie Project as a compelling copper-gold growth story in the Australian mining landscape.
