Summary
Solstice Minerals Limited (ASX: SLS) announced new diamond tail drilling and downhole electromagnetic survey results from its 100%-owned Nanadie Copper-Gold Project in Western Australia that show broad copper-gold mineralisation extending well beyond the current 2022 Inferred Mineral Resource Estimate of 40.4Mt at 0.4% Cu and 0.1g/t Au, with standout results from NANRCD033 in the central deposit returning 48m at 0.59% Cu and 0.16g/t Au from 334.8m and 52m at 0.71% Cu and 0.13g/t Au from 406m including 6m at 1.79% Cu and 0.37g/t Au, while DHEM in that hole defined a 140m x 140m high-conductance plate below the hole near a cross-fault that is considered a compelling sulphide target and is planned to be tested immediately with an 850m EIS co-funded RC/diamond hole; additional step-down results from NANRCD009 in the south, including 28.3m at 0.74% Cu and 0.21g/t Au from 334.8m and 43.8m at 0.55% Cu and 0.19g/t Au from 514.2m, suggest widening mineralisation and improving grade at depth across a 300m corridor, while NANRCD020 in the north confirmed further mineralisation along the eastern side of the host gabbro with 10.2m at 0.41% Cu and 0.19g/t Au from 288m and 23m at 0.41% Cu and 0.05g/t Au from 359m; the company said these results support material resource growth potential, with three rigs operating on site, assays pending from 16 more diamond holes and over 20 RC holes, and strong financial capacity with $45 million cash and no debt to continue expanding Nanadie and testing nearby targets such as Stark.
Key Points
  • Solstice Minerals Limited released the announcement on 17 September 2026 regarding the Nanadie Copper-Gold Project in WA.
  • New diamond tail drilling intersected significant copper-gold mineralisation outside the current Mineral Resource Estimate boundary.
  • Hole NANRCD033 returned 48m at 0.59% Cu and 0.16g/t Au from 334.8m and 52m at 0.71% Cu and 0.13g/t Au from 406m, including 6m at 1.79% Cu and 0.37g/t Au from 408m.
  • Downhole electromagnetic surveying in NANRCD033 identified a 140m x 140m high-conductance plate below the hole adjacent to a local cross-fault.
  • The DHEM conductor is scheduled for immediate drill testing with an 850m EIS co-funded follow-up RC/diamond hole.
  • Hole NANRCD009 in the southern part of the system returned 28.3m at 0.74% Cu and 0.21g/t Au from 334.8m and 43.8m at 0.55% Cu and 0.19g/t Au from 514.2m.
  • Results from NANRCD009 indicate the system is widening and may be increasing in copper sulphides and grade at depth.
  • Hole NANRCD020 in the northern extension returned 10.2m at 0.41% Cu and 0.19g/t Au from 288m and 23m at 0.41% Cu and 0.05g/t Au from 359m.
  • Mineralisation appears preferentially distributed along the eastern side of the host gabbro in both central and northern areas.
  • The company stated there are no known false-positive unmineralised EM conductors in the broader Nanadie system.
  • Nanadie currently hosts an Inferred MRE of 40.4 million tonnes at 0.4% copper and 0.1g/t gold containing 162,000 tonnes of copper and 130,000 ounces of gold.
  • Approximately 90% of the current resource is in fresh rock below shallow weathering and cover.
  • The deposit is on a granted Mining Lease about 100km northwest of Sandstone in Western Australia.
  • Three drill rigs are operating on site and the multi-rig RC and diamond drilling campaign is expected to continue through the rest of 2026.
  • Assays are pending from a further 16 completed diamond holes and more than 20 RC holes.
  • Solstice reported it has $45 million cash and no debt to support ongoing drilling, geophysics and growth programs at Nanadie and nearby Stark.
