Solstice Minerals has identified promising new geophysical targets at its Nanadie Copper-Gold Project, setting the stage for a maiden drilling campaign aimed at expanding its existing resource.
- Dipole-Dipole Induced Polarisation survey reveals strong chargeability anomalies
- Targets located immediately north and south of existing 40.4Mt inferred resource
- Maiden Reverse Circulation drilling planned to test new extensions
- Nanadie deposit lies within granted Mining Lease with shallow cover
- Company holds $15 million cash to support exploration activities
Exploration Advances at Nanadie
Solstice Minerals Limited (ASX, SLS) has announced encouraging results from a recently completed Dipole-Dipole Induced Polarisation (IP) geophysical survey at its 100%-owned Nanadie Copper-Gold Project in Western Australia. The survey has delineated robust chargeability anomalies immediately along strike to the north and south of the current Inferred Mineral Resource Estimate (MRE), which stands at 40.4 million tonnes grading 0.4% copper and 0.1 grams per tonne gold.
The IP chargeability responses align well with geological interpretations and aeromagnetic features, highlighting untested zones that could represent extensions of the known mineralisation. Nanadie is characterised by a near-surface, high-volume body of disseminated and veinlet-style chalcopyrite mineralisation, with widths up to 150 meters and lengths of approximately 900 meters, lying beneath shallow cover generally less than two meters thick.
Strategic Drilling Plans
Building on these geophysical insights, Solstice is prioritising drill hole design for its maiden Reverse Circulation (RC) drilling program scheduled in the coming months. The company’s management is optimistic that successful testing of these IP targets, combined with strong geological extension targets identified in a recent review, could materially increase the existing resource base.
Importantly, the Nanadie deposit and its prospective strike extensions are secured within a large, granted Mining Lease, providing a solid tenure foundation for exploration and potential development. The deposit’s geological setting and mineralisation style are well suited to IP geophysical techniques, which have proven effective in outlining these new targets.
Broader Project and Financial Position
Beyond Nanadie, Solstice continues active exploration at its Yarri Project in the Eastern Goldfields, with recent drilling successes at advanced gold prospects. The company maintains a strong financial position, reporting $15 million in cash as of June 30, 2025, underpinning its capacity to advance exploration and development activities.
CEO Nick Castleden emphasised the strategic value of Nanadie, noting the scarcity of large-scale copper-gold assets in Western Australia with granted mining leases and good operational access. He highlighted copper’s favourable long-term supply-demand outlook and expressed confidence in the potential to grow the Nanadie resource through timely drilling.
Looking Ahead
The upcoming RC drilling campaign represents a critical next step for Solstice, aiming to convert geophysical targets into tangible resource growth. Success here could unlock significant value for the project and position Nanadie as a notable copper-gold asset in the region. Meanwhile, ongoing metallurgical testing and further geological modelling will refine understanding of the deposit’s characteristics and economic potential.
Bottom Line?
Solstice’s maiden drilling at Nanadie could redefine the project’s scale, with market eyes keenly awaiting assay results.
Questions in the middle?
- Will the maiden RC drilling confirm the extent of the new IP chargeability targets?
- How might metallurgical test results impact the economic viability of Nanadie?
- What timelines does Solstice envisage for resource upgrade and potential development?
