SLS Daily Timeframe Chart as of 27 April 2026
Announcement Overview
On 27 April 2026, Solstice Minerals Limited (ASX: SLS) announced the successful completion of its first diamond drill tail at the 100%-owned Nanadie Copper-Gold Project in Western Australia. The hole, NANRCD004, extended prior high-grade reverse circulation results to a final depth of 629.1 metres — making it the deepest hole ever drilled at Nanadie — and intersected multiple zones of visible chalcopyrite mineralisation consistent with earlier drilling that significantly deepens the known mineralised system. Geological logging and core processing are now underway, with assay results expected within approximately six weeks. The diamond campaign is designed to comprise around 10 tails for approximately 2,000 metres of core and is running concurrently with a major 10,000-metre Phase 2 reverse circulation program targeting step-out exploration, resource delineation, and definition of higher-grade positions for future mineral resource estimates. The announcement is material because it demonstrates that high-grade copper-gold mineralisation persists well below the existing resource envelope, supporting the case for a substantially larger deposit than currently defined.

Market Sentiment
SLS surged +21.7% to close at $1.540, setting a new 52-week high of $1.542 intraday. The market reaction reflects growing confidence in Nanadie's scale potential — this is not an isolated event but the latest in a string of positive drilling updates that have driven the stock from $0.175 to $1.54 over the past 12 months, an approximately 780% appreciation. The move was supported by strong volume and follows the company's successful $32.6 million institutional placement at $1.00/share in early April 2026, which was fully allocated to fund precisely this type of drilling activity. Broader sentiment in the copper-gold exploration space remains highly constructive, with copper prices elevated on structural supply deficit concerns and gold at or near record highs. SLS is increasingly seen as one of the ASX's standout copper-gold discovery stories, and the diamond drilling milestone adds a new dimension of depth confirmation to the thesis.
Risks & Considerations
While the visual logging of chalcopyrite at depth is encouraging, assay results are not yet available — investors should note that visible mineralisation does not guarantee economic grades, and the market is partially pricing in a positive outcome approximately six weeks ahead. The existing 40.4Mt Inferred resource is based on a 2012 JORC estimate and will need updating to incorporate the Phase 1 and Phase 2 drilling — until then, there is uncertainty around the final tonnage, grade, and classification uplift. The stock has appreciated ~780% from its 52-week low, implying significant speculative premium and heightened downside risk if results disappoint. Dilution is a factor: the April 2026 placement issued 32.6 million new shares at $1.00, and further capital raises may be required as the project advances toward feasibility. Nanadie remains at an exploration/resource definition stage with no scoping or feasibility study completed, meaning the pathway to production is uncertain and multi-year. Metallurgical test work is underway but results are pending, introducing processing risk. Finally, as a single-asset company (with supplementary gold exploration at Yarri), SLS carries concentrated project risk.

Price Action Analysis
- Previous Close: $1.265
- Close Price (27 April 2026): $1.540
- Move (27 April 2026): +21.7%
- 52-Week Range: $0.175 – $1.542
Key Levels to Watch
Resistance Levels:
- $1.542 (Weak) — current 52-week high; no overhead supply. A breakout here moves into uncharted territory, with the next psychological target at $1.60–$1.70.
Support Levels:
- $1.063 (Very Strong) — roughly aligned with the $1.00 placement price from April 2026; strong institutional demand floor
- $0.975 (Strong) — pre-placement trading range support
- $0.850 (Very Strong) — consolidation zone from the earlier Phase 1 assay-driven rally
Key Takeaways
- SLS surged +21.7% on 27 April 2026 following a price-sensitive ASX disclosure.
- The announcement — Strong Start to Diamond Drilling at Nanadie Project — was the primary catalyst.
- Hole NANRCD004, the deepest ever drilled at Nanadie at 629.1 metres, intersected multiple zones of visible chalcopyrite mineralisation, confirming that the copper-gold system extends significantly below the existing resource envelope.
- The diamond campaign (~10 tails for ~2,000m) is running alongside a large 10,000-metre Phase 2 RC program, representing the most intensive drilling effort in Nanadie's history.
- Assay results from NANRCD004 are expected within approximately six weeks — this is the key near-term catalyst.
- SLS has now appreciated ~780% from its 52-week low of $0.175, reflecting the market's rapid re-rating of Nanadie as a potentially district-scale copper-gold asset in WA.
- Watch $1.542 as immediate resistance (current 52-week high) and $1.063 as key support near the institutional placement floor.
Summary
Solstice Minerals delivered another strong exploration update at its Nanadie Copper-Gold Project, completing the deepest drill hole in the project's history at 629.1 metres and confirming visible chalcopyrite mineralisation at depth — a significant extension of the known system below the existing 40.4Mt Inferred resource. The announcement drove SLS +21.7% to a new 52-week high of $1.542, continuing a remarkable run from $0.175 over the past year. With ~2,000 metres of diamond drilling and a 10,000-metre Phase 2 RC program underway, and backed by the recent $32.6 million institutional placement, SLS is well-funded for sustained exploration intensity through 2026. Investors should focus on the diamond drill assay results due in approximately six weeks as the next major catalyst, while monitoring the broader Phase 2 program for further evidence of resource growth and grade improvement ahead of an anticipated updated MRE.
