Solstice Minerals Unveils Wide High-Grade Copper-Gold Zones at Nanadie

Strong Start to Phase 1 Drilling

Solstice Minerals Limited has delivered a compelling update from its Nanadie Copper-Gold Project in Western Australia, reporting multiple wide and high-grade copper-gold intercepts from the first five holes of a 23-hole Phase 1 reverse circulation drilling campaign. The project, located on a granted mining lease northwest of Sandstone, has returned some of the most impressive assay results to date, including a standout intercept of 22 metres grading 2.78% copper and 1.25 grams per tonne gold.

Expanding the Resource Envelope

These initial results are particularly significant as they extend well beyond the boundaries of the current Mineral Resource Estimate (MRE) of 40.4 million tonnes at 0.4% copper and 0.1g/t gold. The mineralisation remains open at depth and along strike, suggesting that the deposit could be substantially larger than previously understood. Notably, holes NANRC004 and NANRC001 each returned mineralisation over 300 metres to the end of the hole, underscoring the potential scale of the system.

Geological Insights and Future Potential

Geological logging has revealed a broad, mineralised mafic intrusive package over 150 metres wide and at least 900 metres long, flanked by mineralised amphibolite and younger granitoid rocks. This complex geology supports the interpretation of a large, disseminated sulphide system with multiple higher-grade zones. The mineralisation starts just below surface beneath shallow soil cover, which could favour future bulk-tonnage mining methods with low strip ratios.

Well-Funded to Accelerate Growth

With $13.4 million in cash as of the end of 2025, Solstice is well positioned to aggressively pursue further exploration and resource expansion. The company is already planning a Phase 2 drilling program to follow up on these promising results, aiming to delineate additional mineralisation and refine the geological model. CEO Nick Castleden highlighted the strong validation these results provide to the team's geological understanding and the exciting potential for growth at Nanadie.

Strategic Timing Amid Copper Demand

Copper’s long-term supply-demand outlook remains robust, driven by global electrification and infrastructure trends. High-quality copper assets in stable jurisdictions like Western Australia are increasingly sought after, making Nanadie a strategically valuable asset. Solstice’s early success in expanding the resource base could position the company favourably as it advances toward development milestones.
