How Far Can Solstice Minerals Push Nanadie’s Copper-Gold Boundaries?

A Breakthrough in Exploration

Solstice Minerals Limited has delivered a compelling update from its inaugural drilling campaign at the Nanadie Copper-Gold Project, located in Western Australia’s prolific Goldfields region. The recently completed Phase 1 reverse circulation (RC) drilling program, comprising 23 holes over 6,030 metres, has not only confirmed the presence of significant copper-gold mineralisation but also demonstrated that the deposit extends well beyond the boundaries of the current 40.4 million tonne Mineral Resource Estimate (MRE).

The standout results include broad intercepts of copper mineralisation exceeding 0.40% copper, with some zones revealing high-grade copper and gold values. Notably, the northernmost drill hole, NANRC023, returned an impressive 44 metres at 0.52% copper and 0.23 grams per tonne gold from 146 metres depth, including a 14-metre section grading over 1% copper and 0.58 grams per tonne gold. This intercept lies within a thick mineralised zone extending nearly 187 metres, underscoring the scale of the system.

Open-Ended Growth Potential

Crucially, the deposit remains open to the north and at depth, with multiple step-out holes (NANRC020 to NANRC023) intersecting mineralisation beyond the current resource model. These results align with a 2025 induced polarisation (IP) geophysical survey that identified chargeability anomalies trending northward and open at depth, suggesting further exploration upside. The Phase 1 drilling also confirmed widespread mineralisation at the southern end of the deposit, with infill hole NANRC026 returning consistent copper-gold grades over substantial widths.

Solstice’s CEO and Managing Director, Nick Castleden, expressed enthusiasm about the results, highlighting the unexpected discovery of high-grade, high-volume targets below certain drill holes. He emphasised that the Phase 1 program, designed to delineate the edges of the mineralised system, has instead revealed a plethora of new growth avenues, warranting sustained and focused drilling efforts.

Next Steps and Strategic Outlook

Building on this momentum, Solstice is preparing an approximately 8,000-metre Phase 2 RC drilling program aimed at testing the high-grade intercepts identified in earlier holes and expanding exploration into step-out and down-dip targets. The company also plans to deploy diamond drilling to extend selected holes beyond the depth limits of RC drilling, particularly to test promising high-grade plunge targets.

The Nanadie deposit itself is hosted within a layered mafic intrusive complex, with mineralisation characterised by disseminated chalcopyrite and associated precious metals including gold and silver. The existing inferred resource stands at 40.4 million tonnes grading 0.4% copper and 0.1 grams per tonne gold, containing significant quantities of strategic metals. Historical drilling and geophysical surveys have laid a solid foundation, but Solstice’s recent work has markedly advanced the geological understanding and resource potential.

While metallurgical and environmental studies remain in early stages, the company’s methodical approach to sampling, assay verification, and data management ensures robust and reliable results. The ongoing exploration campaign at Nanadie is rapidly shaping up as a key copper-gold growth story in Western Australia, with the potential to significantly enhance Solstice Minerals’ asset base and market profile.
