Nanadie Holds 40.4Mt Resource as Solstice Targets Extensions with New IP Survey

Exploration Momentum Builds at Nanadie

Solstice Minerals Limited (ASX, SLS) has commenced a targeted Induced Polarisation (IP) geophysical survey at its wholly owned Nanadie Well Copper-Gold Deposit in Western Australia. This survey aims to refine and prioritise key extensional targets adjacent to the existing Mineral Resource Estimate (MRE), setting the stage for a maiden Reverse Circulation (RC) drilling campaign scheduled for the third quarter of 2025.

The Nanadie deposit is characterised by a near-surface, disseminated and sulphide veinlet style chalcopyrite mineralisation system, extending up to 150 metres wide and 900 metres long. The deposit currently holds an inferred MRE of 40.4 million tonnes grading 0.4% copper and 0.1 grams per tonne gold, containing approximately 162,000 tonnes of copper and 130,000 ounces of gold. Importantly, the mineralisation remains open along strike and at depth, presenting significant upside potential.

Advancing Geophysical Techniques to Extend Depth

Historical IP surveys over the central resource area demonstrated strong responses coincident with mineralisation but were limited to depths of around 200 metres due to technological constraints at the time. The current IP program is designed with a grid layout to extend the search window to approximately 400 metres vertical depth, targeting the northern and southern strike extensions of the deposit. This deeper and broader coverage could reveal new zones of mineralisation previously undetected.

Solstice’s CEO, Nick Castleden, highlighted the strategic importance of the project, "Western Australian copper-gold assets of scale with granted mining leases are rare. With copper’s favourable long-term supply-demand outlook, expanding Nanadie’s resource base could create significant value for shareholders." The granted Mining Lease securing the Nanadie deposit adds a layer of operational certainty to the exploration plans.

Broader Exploration and Financial Strength

Beyond Nanadie, Solstice continues active gold exploration at its Yarri Project in the Eastern Goldfields, with recent drilling successes at Bluetooth and Statesman Well prospects. The company’s strong cash position, $13.6 million as of March 2025 plus additional funds from a strategic placement, provides a solid foundation to sustain its exploration pipeline through the remainder of the year.

The upcoming IP survey results will be integrated with geological reviews to refine drill targets, with the maiden RC drilling campaign poised to test these high-priority zones. Success in this phase could materially increase the Nanadie resource, potentially repositioning Solstice as a significant player in the copper-gold sector.
