Nanadie Project (100%)

(Copper-Gold)

The Nanadie Copper-Gold Project is located 95km south-east of Meekatharra in the Murchison District, Western Australia. It comprises granted licences M51/887, E51/1040, E51/1987 and L51/124 and exploration licence application E20/1097 covering a total of 137km2.

Nanadie represents a low cost, high leverage copper opportunity underpinned by an existing JORC-compliant Inferred Mineral Resource Estimate (MRE) of 40.4Mt @ 0.4% copper and 0.1g/t gold for 162kt of contained copper and 130koz gold. The deposit sits in a zone up to 150m wide by 900m long, extends to surface and is under-explored at the margins, depth, and along strike – offering exceptional exploration upside.

The MRE sits within a granted Mining Lease in a typical flat northern Goldfields setting, with sand-covered strike extensions that offer greenfield targets for shallow drilling and the dominantly sulphide mineralisation is a style that lends itself to simple float extraction. No deleterious elements have been noted in available multi-element data, and Solstice expects that planned sighter metallurgical test work will demonstrate a commercial concentrate could be produced.

Impressive previous drill intercepts demonstrate the strength of the Nanadie mineralised system:

  • 107.8m @ 0.91% Cu and 0.24g/t Au from 80.3m in NWD2003, including:
    • 16m @ 1.65% Cu and 0.42g/t Au from 87m, and
    • 7m @ 2.94% Cu and 0.45g/t Au from 155m, and
    • 13.2m @ 1.05% Cu and 0.56g/t Au from 167.8m
  • 76m @ 0.85% Cu and 0.39g/t Au from 25m in NWD2004, including:
    • 10.2m @ 2.61% Cu and 2.06g/t Au from 77.8m, and
    • 59.8m @ 0.63% Cu and 0.15g/t Au from 109m
  • 122.3m @ 0.61% Cu and 0.15g/t Au from 155.9m in NWD2101, including:
    • 24.6m @ 1.23% Cu and 0.22g/t Au from 210.6m
  • 81m @ 0.79% Cu and 0.23g/t Au from 16m in NRC05020, including:
    • 16m @ 2.1% Cu and 0.54g/t Au from 35m, and
    • 9m @ 1.57% Cu and 0.56g/t Au from 62m

Nanadie Project Location Map


Copper has a strong demand outlook, and Solstice is excited by the scale, geometry and MRE growth potential, and recognises that mafic magmatic systems like these can also deliver zones of increased grade.

Systematic re-logging of historical drill holes has resulted in increased understanding of the copper-gold mineralisation. Extrapolation of the host mafic intrusive package and an updated structural interpretation has opened up step-out MRE expansion targets beyond the margins of the current MRE. In particular the south-eastern portion of the MRE remains unconstrained at the margins of drilling information and offers additional potential for fold and/or fault repetitions to extend the host geology eastward. Drillholes in this portion of the MRE are commonly mineralised to the end of hole, demonstrating the potential to significantly widen and extend the system.

Further opportunity has also been observed toward the northwestern edges of the mineralised system where mineralisation may extend toward the west and the entire Nanadie system remains open at depth.
