Solstice Minerals Expands Exploration Footprint at Nanadie with Stark Prospect Highlights

Geological Review Unlocks New Growth Avenues at Nanadie

Solstice Minerals (ASX:SLS) has significantly expanded the exploration potential at its 100%-owned Nanadie Copper-Gold Project in Western Australia following a detailed geological review. The updated interpretation identifies multiple new growth targets, notably highlighting the Stark copper prospect located just 1km southeast of Nanadie as a parallel mineralised system. This revelation opens the door to potential strike extensions and structural repetitions both at Stark and in underexplored soil-covered zones north of existing drilling.

Stark Prospect's Historical Drilling Signals Untapped Potential

Historical reverse circulation (RC) and diamond drilling at Stark, conducted by Mithril Resources and Cyprium Metals, reveals promising copper intercepts including 40m at 0.44% Cu and 17m at 0.65% Cu in hole SRC21005, 10m at 1.05% Cu in NRC15002, and 30m at 0.56% Cu in NRC14008. These results suggest that Stark shares the same magmatic copper-gold event as Nanadie, with later deformation and alteration processes likely responsible for higher-grade zones. Despite these encouraging intercepts, Stark remains sparsely tested along strike and at depth, particularly beneath transported cover to the north.

Phase 2 Drilling Advances Resource Expansion Prospects

Ongoing Phase 2 RC and diamond drilling at Nanadie continues to confirm extensive disseminated and structurally controlled chalcopyrite mineralisation over a strike length of at least 1.2km, with the system remaining open to both the north and south. The mineralisation strongly correlates with a large induced polarisation (IP) chargeability anomaly, underscoring the robustness of the geological model. Recent step-out drilling has extended mineralisation beyond the current 40.4 million tonnes Mineral Resource Estimate (MRE), which contains 162,000 tonnes of copper and 130,000 ounces of gold. Processing of diamond core and assay dispatches are underway, with a steady stream of results expected in the coming months.

Expanded Exploration Corridor and Future Targets

Beyond the established resource, historical reconnaissance drilling has identified copper anomalism extending approximately 1.7km northwest of Nanadie, while southern extensions remain largely untested. Similarly, a multi-kilometre soil-covered extension of the Stark aeromagnetic trend lies completely untested beneath transported cover. The revised geological model has thus defined a materially expanded exploration corridor northwards from Nanadie and Stark, prioritising upcoming geophysical surveys and reconnaissance drilling to test these promising targets.

Strategic Review of Eastern Goldfields Projects

In parallel with its focus on Nanadie, Solstice has initiated a strategic review of its Eastern Goldfields Projects, which include the Yarri Gold Project, Ponton Gold Project, and Ringlock Nickel-Copper-Gold Project. The review aims to maximise shareholder value by exploring options such as retention, partial or full sale, or a potential demerger distributing shares in a separate entity to Solstice shareholders. The outcomes remain uncertain, with further updates expected as the process unfolds.
