Highlights

  • Solstice continued multi-rig copper-gold exploration at its Nanadie project in Western Australia during 2026.
  • The existing Nanadie Inferred Mineral Resource Estimate is 40.4 million tonnes at 0.4% copper and 0.1g/t gold.
  • September drilling included a 169.3-metre intercept at 0.87% copper and 0.29g/t gold.
  • October assay results identified additional mineralised intervals beyond the current resource boundary.
  • The September-quarter company report disclosed $41.3 million cash and no debt.

Solstice Minerals Limited (ASX:SLS) explores for copper and gold in Western Australia, with its wholly owned Nanadie Copper-Gold Project a principal focus of drilling. The company also holds exploration interests at Yarri and Ringlock. Its 2026 Nanadie drilling program has produced copper-gold intersections beyond the limits of the existing Inferred Mineral Resource Estimate, adding geological information for future resource work. Those drilling results do not themselves establish an enlarged mineral resource or an economically viable operation.

Nanadie Drilling Extends Beyond the Resource Boundary

The existing Nanadie resource stands at 40.4 million tonnes grading 0.4% copper and 0.1 grams per tonne gold, containing approximately 162,000 tonnes of copper and 130,000 ounces of gold. This estimate is classified as Inferred, indicating that geological confidence remains limited compared with higher-confidence resource categories. Solstice Minerals (ASX:SLS) is testing extensions along strike and at depth rather than reporting a producing mine.

In a 29 September 2026 announcement, the company reported a combined reverse circulation and diamond intercept from NANRCD001 of 169.3 metres at 0.87% copper and 0.29g/t gold. Within that result was 73.3 metres at 1.07% copper and 0.26g/t gold from 299 metres. The company also reported mineralisation east of the previously expected host-rock contact, identifying an additional target area requiring drilling.

October Assays Add to the Geological Picture

A further company release dated 13 October 2026 described five new diamond tails at Nanadie. Reported intercepts included 64.1 metres at 0.94% copper and 0.23g/t gold in NANRCD014, and 91.4 metres at 0.97% copper and 0.42g/t gold in NANRCD058. The results expand the available dataset, although continuity, overall grade distribution and resource classification still need to be determined through subsequent geological modelling and estimation.

The quarterly activities report issued in late October described the mineralised zone as extending over at least 1.5 kilometres of strike and around 100–200 metres in width. It also identified the eastern margin of the host gabbro as a priority for systematic testing. Solstice Minerals (ASX:SLS) reported assays pending from more than 60 holes, providing further information for assessment as results become available.

Cash Position and Exploration Priorities

The September 2026 quarterly report stated that Solstice Minerals (ASX:SLS) held $41.3 million in cash and had no debt. This balance provides a measure of funding for continued drilling and evaluation; it does not establish the cost or financing arrangements for any future development. The company also reported a substantial exploration workload during the quarter, reflecting its emphasis on defining the Nanadie mineralised system.

Yarri and Ringlock provide additional gold exploration exposure, while current technical updates principally concern Nanadie.

What Remains Uncertain at Nanadie?

Exploration intercepts show mineralisation at specific drill locations and should not be interpreted as ore reserves, project cash flows or proof of commercial extraction. Further drilling, metallurgical testing, technical studies and approvals would be needed before a mine development decision could be considered. Copper and gold prices could also affect future project economics. For Solstice Minerals (ASX:SLS), the distinction between promising intercepts and a compliant, economically assessed resource remains material.

Key Insights

Solstice Minerals (ASX:SLS) has reported progressively more drilling information at Nanadie throughout 2026, including September and October intersections beyond its existing 40.4-million-tonne Inferred resource boundary. Its disclosed cash position supports continued exploration. The principal unresolved questions concern continuity, updated mineral resources, processing characteristics and economic feasibility, rather than short-term share-price movements.
