ACB News (9 February 2026) — Despite heightened volatility across the Australian share market last week, Western Australia-focused gold and copper-gold explorer Solstice Minerals Limited (ASX: SLS) delivered standout performance after releasing its latest exploration update, with the company’s share price recording a sharp rise over the week.

Last Tuesday, Solstice announced a new batch of drilling results fromits Nanadie Copper-Gold Project, attracting strong market attention. The stock moved sharply higher over the week, delivering a weekly gain of approximately 157%.

According to the exploration update released by the company, Solstice’s ongoing resource extension drilling program at Nanadie has delivered its first set of results, with multiple drill holes intersecting broad, high-grade copper-gold mineralisation. Several mineralised intervals were also recorded outside the boundaries of the current resource model, indicating potential for further resource expansion.

The reported results relate to the first five drill holes of a planned 23-hole reverse circulation (RC) drilling program designed to test extensions beyond the existing Mineral Resource Estimate (MRE). The company stated that the mineralised system remains open in multiple directions and that drilling continues.

Multiple Holes End in Mineralisation

High-Grade Intercepts Extend Beyond Existing Resource Boundary

Key drilling highlights include:

62 metres at 1.55% copper and 0.66 g/t gold, including

22 metres at 2.78% copper and 1.25 g/t gold (Hole: NANRC004); and

97 metres at 0.73% copper and 0.30 g/t gold (Hole: NANRC001).

Solstice noted that some drill holes remained mineralised at the planned end-of-hole depth, indicating the copper-gold system remains open at depth. The company also confirmed that several high-grade intercepts were achieved outside the existing JORC resource model, providing further support for the project’s resource growth potential.

Resource Overview

The Nanadie Copper-Gold Project currently hosts a JORC 2012 Inferred Mineral Resource of 40.4 million tonnes, containing approximately 162,000 tonnes of copper and 130,000 ounces of gold. Solstice stated that the latest drilling results confirm mineralisation continuity beyond the current resource boundary, and the new data will be used to guide follow-up drilling and further resource evaluation work.

In terms of mineralisation style, Nanadie is characterised by broad zones of large-scale disseminated copper-gold sulphide mineralisation. The company noted that the project’s scale and development potential will require further drilling and technical studies for verification.

Further Assay Results Pending

Solstice stated that the drilling program remains underway, with assay results from the remaining 18 RC drill holes expected to be released progressively over the coming weeks. The company said these results will assist in planning the next stage of drilling and assessing the potential for a future resource update.

As at the end of December 2025, Solstice reported cash reserves of approximately A$13.4 million, and stated that its current funding position supports continued exploration activities at Nanadie and across its broader Western Australian portfolio.

Secondary Market Share Price Performance

In the secondary market, Solstice Minerals’ share price recorded significant movement last week following the announcement. After the drilling update was released on Tuesday, the stock opened with a price gap and trading volume increased. Over the following sessions, the share price continued to rise as turnover remained elevated.

By last Friday’s close, Solstice Minerals was trading around A$1.17. Based on this level, the company’s share price increased by approximately 157.14% over the week.
