Solstice Minerals Extends Nanadie Deposit with 148m Copper-Gold Intercept

Record-Length Copper-Gold Intercept Broadens Nanadie

Solstice Minerals (ASX:SLS) has unveiled a game-changing combined diamond and RC drilling intercept of 148 metres grading 0.77% copper and 0.20 grams per tonne gold from 201 metres depth at its 100%-owned Nanadie Copper-Gold Project in Western Australia's Goldfields. This intercept, recorded in hole NANRCD018, pushes mineralisation well beyond the current Mineral Resource Estimate (MRE) boundary and signals a growing footprint for what is shaping up to be a large-volume copper-gold system.

The diamond tail component alone added an extra 43.4 metres at 0.56% copper and 0.15g/t gold, reinforcing the scale of mineralisation. Nearby, a 51-metre intercept at 1.03% copper and 0.29g/t gold in RC hole NANRC041 complements this high-grade zone, suggesting a robust mineralised position north of a local cross-fault and largely outside the existing resource limits.

Step-Out Drilling Confirms Southern Extensions

Beyond depth extensions, Solstice's step-out RC drilling on three traverses south of the current MRE boundary has delivered multiple significant intercepts that extend the Nanadie deposit strike. Highlights include 43m at 0.59% copper and 0.21g/t gold from 175m in NANRC044, and 47m at 0.45% copper and 0.19g/t gold from 209m in NANRC045, among others. These results support a south-plunging mineralisation system with potential for higher-grade zones at depth, exemplified by a standout 1m intercept grading 3.60% copper and 3.26g/t gold from 278m in NANRC051.

Deepest Drilling Targets Mineralised Host Rock

Diamond drilling continues to probe the system's geometry and depth, with assays pending from the 841m deep step-down hole NANRCD005. This hole is interpreted to have intersected prospective host geology and sulphide mineralisation approximately 500 metres below the current MRE boundary, marking the deepest hole to date. Previous diamond hole NANRCD004 delivered a remarkable combined intercept of 639 metres at 0.50% copper and 0.17g/t gold, underscoring the deposit's vertical potential.

Accelerated Drilling and Expanding Footprint

With a second RC rig due on site imminently, Solstice is set to accelerate its drilling campaign, which now extends over a mineralised footprint roughly 100-200 metres wide and at least 1.2 kilometres in strike length. The system remains open both at depth and along strike, with ongoing assays expected from 12 diamond tails and 18 RC holes. The company’s geological model is being refined continuously, with visible chalcopyrite mineralisation correlating well with assay results, bolstering confidence in identifying further high-grade zones.

Nanadie’s Strategic Position and Future Prospects

Nanadie hosts an existing Inferred Mineral Resource Estimate of 40.4 million tonnes at 0.4% copper and 0.1g/t gold, containing 162,000 tonnes of copper and 130,000 ounces of gold. The deposit is situated within the Barrambie Igneous Complex, a layered mafic intrusive system known for its copper sulphide mineralisation. Solstice’s CEO Nick Castleden emphasised the ongoing drilling's role in validating and expanding the geological model, highlighting multiple emerging high-grade zones and the potential for resource growth well beyond current boundaries.

With $45 million cash and no debt, Solstice is well positioned to capitalize on these exploration successes. The company is also investigating geophysical techniques such as downhole electromagnetic surveys to better understand the controls on high-grade mineralisation. Additionally, exploration corridors extending north from Nanadie and the nearby Stark Prospect offer further upside potential beneath shallow transported cover.
