Solstice Minerals' Nanadie Discovery Keeps Growing With Depth
Drilling confirmed mineralisation extending well below the existing resource at a rare magmatic copper deposit already sitting on a granted mining lease.
15 Jul 2026 · 2 min read
In short
Solstice Minerals rallied more than 50% as drilling at its Nanadie copper-gold project confirmed mineralisation extending to more than 600 metres depth and remaining open, highlighting potential for the deposit to grow.
Terra Capital describes Nanadie as a standout copper discovery, currently 40 million tonnes at 0.40% copper and 0.11 grams per tonne gold, with rare magmatic copper-dominant geology potentially supporting a 30,000-50,000 tonne per annum open-cut operation.
The project's location on an already-granted WA mining lease with sealed-road access could allow faster development through the permitting process compared with greenfield discoveries.
Solstice Minerals rallied more than 50 percent as drilling at its Nanadie copper-gold project near Meekatharra in Western Australia confirmed mineralisation extending well below the existing resource, with fund managers valuing the deposit's rare magmatic copper-dominant geology and fully permitted mining lease as combining genuine scale with a rapid pathway to development.
Deeper drilling confirms a growing resource
Wilson Asset Management said Solstice Minerals is advancing the Nanadie Copper-Gold Project near Meekatharra in Western Australia, releasing visual results in April from deeper drilling below earlier high-grade copper hits, suggesting the mineral system extends well below the current resource and highlighting the deposit's potential scale, with the fund seeing share price upside as drilling helps define a larger resource. In June, the fund said updated drilling results from the first diamond drilling program confirmed the mineralised system extends to depths of more than 600 metres and remains open at depth, with mineralisation continuing well below the existing resource, highlighting the potential for the deposit to grow.

A standout discovery with rare geology and fast-track permitting
Terra Capital highlighted Nanadie as a standout copper discovery, currently 40 million tonnes at 0.40 percent copper and 0.11 grams per tonne gold on an inferred JORC basis, with the thesis resting on the deposit's rare magmatic copper-dominant geology, a drilling campaign extending grade and depth well beyond the existing resource, potentially supporting a 30,000 to 50,000 tonne per annum open-cut operation, and full permitting on a granted WA mining lease with sealed-road access. Acorn Capital's Squire said the Western Australian copper discovery combines the two characteristics he values most: genuine scale and a location already covered by a mining lease, which could allow future development to progress more quickly through the permitting process.

A structural copper supply-demand thesis
Wilson Asset Management said it held copper exposure through Solstice Minerals, reflecting its positive view on supply and demand dynamics in the copper market.
What fund managers say they are watching next is continued drilling to define a larger resource given mineralisation remains open at depth, progress toward a potential 30,000 to 50,000 tonne per annum open-cut operation, benefits from the already-granted WA mining lease speeding permitting, and whether the structural copper supply-demand thesis continues supporting the stock.
Questions
What did recent drilling reveal about Solstice Minerals' Nanadie project?
Drilling confirmed the mineralised system at Nanadie extends to depths of more than 600 metres and remains open at depth, with mineralisation continuing well below the existing resource, highlighting potential for the deposit to grow.
Why is Solstice Minerals' Nanadie project considered a fast-track development opportunity?
Acorn Capital notes the project sits on an already-granted WA mining lease with sealed-road access, which could allow future development to progress more quickly through the permitting process compared with greenfield discoveries.
What makes Nanadie's copper geology unusual?
Terra Capital highlights the deposit's rare magmatic copper-dominant geology, currently estimated at 40 million tonnes at 0.40% copper and 0.11 grams per tonne gold, potentially supporting a 30,000-50,000 tonne per annum open-cut operation.
