Solstice Minerals Expands Nanadie Copper-Gold System with 629m High-Grade Drill Intercept

• 629.1m @ 0.50% Cu, 0.17g/t Au drill intercept extends mineralisation 300m below resource
• Phase 2 drilling confirms strike and depth extensions, deposit remains open-ended
• Nanadie hosts 40.4Mt inferred resource with potential for significant expansion
• Solstice holds $45 million cash, no debt, supporting aggressive drilling program
• Strategic review underway for Eastern Goldfields projects including potential sale or demerger

Massive Drillhole Confirms Nanadie’s Depth and Grade Potential

Solstice Minerals (ASX:SLS) has punched well below the surface at its Nanadie Copper-Gold Project in Western Australia, returning a colossal 629.1-metre drill intercept grading 0.50% copper and 0.17g/t gold from surface to end of hole. This combined reverse circulation and diamond tail hole, NANRCD004, extends the known mineralisation more than 300 metres beneath the current 40.4 million tonne inferred Mineral Resource Estimate (MRE), underscoring Nanadie’s potential to evolve into a large-volume copper-gold system in WA’s premier Goldfields mining jurisdiction.

The intercept includes multiple high-grade zones, such as 15 metres at 2.12% copper and 0.47g/t gold, and broad intervals of mineralisation consistent with visible chalcopyrite sulphides logged in the core. This result is comparable in scale and grade to some of the world’s significant Andean copper-gold deposits, a notable achievement for a project still in the resource expansion phase.

Ongoing Drilling Extends Mineralisation Along Strike and at Depth

Phase 2 drilling continues to push Nanadie’s boundaries, with recent reverse circulation holes extending mineralisation at least 160 metres north of the current MRE. Intercepts such as 44 metres at 0.52% copper and 0.14g/t gold in NANRC030, and 32 metres at 0.60% copper in NANRC029, highlight the deposit’s strike potential, which remains open both north and south over at least 1.2 kilometres. The deposit’s width of 100-200 metres and open-ended depth profile provide multiple avenues for resource growth.

Diamond drilling is also probing down-plunge extensions, with assays pending from 12 additional diamond tails. The company’s upgraded field infrastructure supports accelerated drilling, including multi-rig operations and faster core processing, positioning Solstice to maintain a steady flow of exploration news and resource updates in the coming months.

Nanadie’s Geological Model Refined with Stark Prospect Parallels

An independent geological review has refined Solstice’s understanding of Nanadie’s mineralised system, identifying strong genetic similarities with the nearby Stark deposit located 1 kilometre southeast. Both deposits feature disseminated copper-gold mineralisation within mafic intrusive rocks, with remobilisation events producing wide zones of high-grade mineralisation. This enhanced model expands the exploration search window, revealing high-priority strike targets and untested corridors beneath shallow cover that will be the focus of upcoming geophysical surveys and drilling programs.

Eastern Goldfields Portfolio Advances Amid Strategic Review

While Nanadie remains the flagship focus, Solstice is progressing its broader Eastern Goldfields portfolio, including the Yarri Gold Project and the Bluetooth Gold Prospect. Yarri spans over 1,500 square kilometres across structurally significant corridors hosting major gold deposits, with recent tenure grants unlocking new targets for aircore drilling. Bluetooth has emerged as a promising near-surface gold discovery, with thick oxide zones showing intercepts up to 18 metres at 3.06g/t gold, suggesting open-pit potential.

Solstice has initiated a strategic review of its Eastern Goldfields assets, considering options such as partial or full sale, or a demerger to unlock shareholder value. Any such moves would require shareholder approval and regulatory clearances, indicating a period of corporate activity alongside exploration progress.

Robust Financial Position Supports Exploration Ambitions

Solstice closed the June quarter with a strong cash balance of $45.26 million and no debt, following exploration expenditure of $3.19 million during the period. The company also secured a $200,000 co-funded drilling grant from the Western Australian Government’s Exploration Incentive Scheme, providing external validation and additional financial support for its step-down exploration targeting plunge corridors.

This robust financial footing enables Solstice to sustain its aggressive drilling campaigns at Nanadie and across its other projects, positioning the company well to capitalise on favourable copper and gold market dynamics amid tightening supply fundamentals.

Bottom Line?

Solstice’s expansive drill results at Nanadie and strong cash position set the stage for significant resource growth, but pending assays and strategic decisions on Eastern Goldfields assets will be key to watch.

Questions in the middle?

• How will pending assays from 12 diamond tails influence Nanadie’s next resource update?
• What strategic direction will Solstice take with its Eastern Goldfields projects amid the ongoing review?
• Can Nanadie’s open-ended mineralisation translate into a large-scale, economically viable mine?
