Solstice Minerals Limited announced further strong diamond drilling results from its 100%-owned Nanadie Copper-Gold Project in Western Australia’s Goldfields, reporting that five new diamond tails extended previous RC holes well beyond the current 2022 Mineral Resource Estimate boundary and reinforced the potential to materially increase both the size and grade of the existing inferred resource of 40.4Mt at 0.4% Cu and 0.1g/t Au; standout results included NANRCD014 with 54.8m at 0.83% Cu and 0.30g/t Au from 453m and 64.1m at 0.94% Cu and 0.23g/t Au from 520.9m, NANRCD042 with partial assays including 18m at 1.11% Cu and 0.56g/t Au from 382m, NANRCD017 with broad mineralisation below the MRE including 60.0m at 0.59% Cu and 0.18g/t Au from 372m and 45.8m at 0.80% Cu and 0.16g/t Au from 452.1m plus a high-grade silver zone of 7m at 1,019g/t Ag from 499m including 2m at 3,103g/t Ag, NANRCD058 with a combined RC-diamond intercept of 91.4m at 0.97% Cu and 0.42g/t Au from 143m including 4.9m at 4.67% Cu and 1.01g/t Au, and NANRCD059 with 25.4m at 1.00% Cu and 0.15g/t Au from 450.6m; the results highlight a laterally extensive, high-grade copper-gold zone along the eastern margin of the host gabbro, with shallow mineralisation north of a local cross-fault considered potentially valuable for future pit optimisation, while three rigs continue drilling, assays remain pending from 13 diamond holes and over 30 RC holes, and the company said its $45 million cash balance at 30 June 2026 and debt-free position supports continued resource growth and testing of additional targets at Nanadie and nearby Stark.
Key Points
ASX announcement dated 13 October 2026 from Solstice Minerals Limited (ASX: SLS) on the Nanadie Copper-Gold Project.
Five new diamond tail holes returned significant copper-gold results beyond the current Mineral Resource Estimate boundary.
NANRCD014 delivered 54.8m at 0.83% Cu and 0.30g/t Au from 453m, including 25.6m at 1.33% Cu and 0.53g/t Au.
NANRCD014 also delivered 64.1m at 0.94% Cu and 0.23g/t Au from 520.9m, including 23.7m at 1.49% Cu and 0.44g/t Au and 6m at 2.26% Cu and 0.33g/t Au.
NANRCD042 returned partial results including 16.1m at 0.69% Cu and 0.18g/t Au from 218.4m and 18m at 1.11% Cu and 0.56g/t Au from 382m, with more assays pending.
NANRCD017 returned 60.0m at 0.59% Cu and 0.18g/t Au from 372m and 45.8m at 0.80% Cu and 0.16g/t Au from 452.1m below the current MRE.
NANRCD017 also intersected exceptional silver grades of 7m at 1,019g/t Ag from 499m including 2m at 3,103g/t Ag.
NANRCD058 extended a previously reported RC hit to a combined intercept of 91.4m at 0.97% Cu and 0.42g/t Au from 143m, including 4.9m at 4.67% Cu and 1.01g/t Au.
NANRCD059 returned broad mineralisation including 32m at 0.43% Cu and 0.05g/t Au from 385m and 25.4m at 1.00% Cu and 0.15g/t Au from 450.6m.
The eastern margin of the host gabbro is emerging as a key Mineral Resource expansion target with broad copper-gold mineralisation.
Mineralisation north of the local cross-fault includes shallow wide high-grade zones that may improve future open pit optimisation and early mine planning.
The existing inferred resource at Nanadie is 40.4 million tonnes at 0.4% Cu and 0.1g/t Au, containing 162,000 tonnes of copper and 130,000 ounces of gold.
Three drill rigs are operating at Nanadie and drilling is expected to continue through the rest of calendar 2026.
Assays are pending from 13 completed diamond holes and more than 30 RC holes.
Solstice reported cash of $45 million at 30 June 2026 and no debt, supporting continued drilling and geophysical work at Nanadie and nearby Stark.
