Solstice Minerals expands Nanadie copper‑gold system; Resolution Minerals advances US antimony project

Solstice Minerals (ASX:SLS) announced significant drill intercepts that extend the copper‑gold mineralisation at its Nanadie project in Western Australia beyond the current resource boundary. Nine of ten reverse‑circulation holes returned notable results, including 51 m at 1.03 % Cu and 0.29 g/t Au, 97 m at 0.57 % Cu and 0.16 g/t Au, and 30 m at 1.15 % Cu and 0.25 g/t Au. CEO Nick Castleden said, “Every new batch of drill results reveals a much larger copper‑gold system than previously recognised.” The company says the system now measures 100–200 m wide and at least 1.2 km long and remains open along strike and at depth.

Resolution Minerals (ASX:RML) reported progress on its Horse Heaven antimony‑tungsten‑gold‑silver project in Idaho, USA. The firm secured FAST‑41 transparency coverage for the Antimony Ridge area, completed three‑dimensional modelling that identified more than 100 antimony‑bearing veins, and began a Phase 2 drilling campaign at the Golden Gate target. A $20 million capital raise strengthened its balance sheet, and metallurgical test work demonstrated the potential for high‑purity antimony trioxide production, supporting its strategy to build a domestic critical‑minerals supply chain.
