Solstice Minerals Hits 169m at 0.87% Copper Expanding Nanadie to 1.5km Strike
Solstice Minerals (ASX: SLS) has identified several promising extension targets at its Nanadie Copper-Gold Project that could substantially increase the size of the current mineral resource. The company's methodical geological work has revealed opportunities to expand the existing 40.4 million tonne resource both laterally and at depth.
A systematic re-evaluation of historical drilling data at the Nanadie Copper-Gold Deposit has uncovered multiple extension targets with the potential to dramatically expand the current mineral resource estimate (MRE). The existing inferred resource stands at 40.4Mt @ 0.4% copper and 0.1g/t gold, containing 162,000 tonnes of copper and 130,000 ounces of gold.
The Nanadie deposit, which sits within a granted Mining Lease approximately 100km northwest of Sandstone in Western Australia, currently spans a mineralised system 150m wide and 900m long. The newly identified expansion targets could substantially increase these dimensions.
"Excellent progress is being made at Nanadie," said Nick Castleden, Solstice Minerals' CEO and Managing Director. "The first-principles review of the copper-sulphide system confirms outstanding options for MRE volume-add while also potentially guiding us toward new high-grade material as we build our understanding of the system."
Key expansion opportunities include:
Copper sulphide deposits like Nanadie typically form in mafic intrusive environments where metal-rich fluids concentrate during geological processes. The high-grade nature of Nanadie is demonstrated by numerous impressive historical drill intercepts, including:
What makes Nanadie particularly interesting is that approximately 90% of the mineral resource is fresh rock mineralisation below 40m depth. This comprises disseminated and remobilised veinlet style chalcopyrite with significant zones exceeding 1% copper where vein density increases. Importantly, increased chalcopyrite veining typically brings significantly higher gold values—a valuable bonus for potential economics.
For investors, understanding the geological setting helps explain why the expansion potential is so significant. The unconstrained boundaries and open-ended nature of the deposit suggest the current resource may represent only a fraction of the total mineralised system.
Solstice is preparing for a maiden Reverse Circulation (RC) drilling programme specifically designed to validate these extension targets. Success in this initial phase would pave the way for systematic drilling and potentially a material increase in the mineral resource estimate.
The drilling will focus on several key areas:
Additionally, field mapping has identified shallow, soil-covered southern strike extensions of the host intrusive package that could contain geological analogues to the main Nanadie deposit.
| Target Area | Expansion Potential | Supporting Evidence |
|---|---|---|
| Southeast | Lateral extension, possible fold/fault repetitions | Mineralisation open at drill hole ends, IP and magnetic responses |
| Northwest | Westward and downward extension | Revised structural interpretation, geophysical support |
| Depth | Vertical extension beneath current ~255m limit | Limited deep drilling, system remains open |
| Southern Strike | New parallel mineralised zones | Field mapping of host intrusive package |
With a robust cash position of $13.6 million as of March 31, 2025, Solstice is well-funded to advance its exploration and development strategy. This financial strength provides flexibility to progress key projects and consider compatible business opportunities.
The company's portfolio extends beyond Nanadie, with significant gold prospectivity at its Yarri Project, where Solstice has carefully selected 1,650km² of tenure close to existing mining operations and processing facilities. Recent RC drilling at the Bluetooth, Statesman Well, and Edjudina Range Prospects has been completed, with results pending.
Planned activities for 2025 include:
Copper continues to have a favourable long-term supply-demand outlook, driven by the global energy transition and electrification trends. Quality growth assets with good geometry and scale, secured by granted Mining Lease tenure and with limited competing land use, are increasingly rare.
Nanadie stands out as a strategic asset for several reasons:
"We are confident that significant value can be created at Nanadie through considered and timely Mineral Resource expansion," noted Castleden.
For investors looking for exposure to strategic metals with strong future demand projections, Solstice Minerals presents a compelling opportunity at the intersection of copper and gold development.
