Solstice Minerals Advances Copper-Gold Projects Across Western Australia

Solstice Minerals has capped off 2025 with a comprehensive year-end exploration update that demonstrates significant progress across its dual-metal strategy, advancing both Solstice Minerals copper-gold projects at Nanadie and expanding gold discoveries at the Yarri Project in Western Australia's proven mining districts.

Strategic Copper-Gold Asset Gains Momentum at Nanadie

The company's flagship Nanadie Copper-Gold Project is delivering on its promise as a substantial near-surface resource. With 162,000 tonnes of copper and 130,000 ounces of gold contained within a 40-million-tonne Inferred Mineral Resource, Nanadie represents a strategic copper play in an increasingly supply-constrained market.

The current 5,000-metre Phase 1 RC drilling programme has completed 13 holes for 3,619 metres, with drilling consistently achieving depths beyond 300 metres and maintaining excellent sample quality. Importantly, initial field observations suggest the mineralised system has significant room for expansion beyond current resource boundaries.

Key Nanadie Statistics:

• 40Mt Inferred Resource containing 162,000t Cu and 130,000oz Au
• 13 RC holes completed averaging 278m depth
• First assays expected January 2025
• Substantial expansion potential identified

CEO Nick Castleden commented: "Nanadie represents a substantial and strategic near-surface bank of copper, a metal with a strong demand and challenging supply outlook. We are working toward expanding an already significant body of copper-gold mineralisation lying hidden and only partly defined below shallow soil cover."

Gold Discovery Pipeline Accelerates at Yarri Project

The company's 1,600km² Yarri Project continues to generate multiple high-grade gold discoveries, with Bluetooth Gold Prospect emerging as a standout performer. Recent RC drilling has delivered consistently strong intercepts including 18m @ 3.06g/t Au within 30m @ 2.06g/t Au, demonstrating the potential for substantial near-surface oxide gold resources.

Bluetooth Gold Prospect Highlights:

• 18m @ 3.06g/t Au (within 30m @ 2.06g/t Au)
• 29m @ 1.58g/t Au
• 20m @ 1.98g/t Au
• 23m @ 1.38g/t Au
• 2,000m RC programme planned Q1 2026

Furthermore, the Edjudina Range discovery is proving equally promising, with high-grade fresh rock intercepts confirming a new mineralised system. Results including 2m @ 11.10g/t Au (including 1m @ 20.90g/t Au) validate the discovery's potential as a regional gold system with significant exploration upside.

Understanding Resource Expansion: Why Margin Testing Matters

For investors new to mining exploration, margin testing refers to drilling around the edges of known mineralisation to define its full extent. At Nanadie, previous drilling rarely extended beyond the mineralised zone, meaning the true size of the system remains unknown.

This approach is particularly valuable because it can lead to substantial resource increases without the discovery risk associated with greenfield exploration. Success in margin testing often provides the fastest path to meaningful resource growth, making it a lower-risk strategy for expanding existing assets.

Why This Matters for Investors

• Lower geological risk compared to greenfield exploration
• Potential for significant resource growth from systematic drilling
• Near-term catalyst potential from assay results

Margin testing systematically explores the boundaries of known mineralisation through strategic drilling programmes. Companies typically drill on a grid pattern extending outward from established mineral zones, with hole spacing designed to test geological continuity whilst maintaining cost efficiency.

The technique proves particularly effective in disseminated copper-gold systems like Nanadie, where mineralisation boundaries may extend well beyond initial drilling coverage. Previous operators often focused on central high-grade zones rather than testing full system extent, creating expansion opportunities for current explorers.

Strong Financial Position Enables Aggressive Exploration

With approximately $14 million in cash and no debt, Solstice is well-positioned to capitalise on exploration success across both projects. This financial flexibility allows the company to:

• Accelerate drilling programmes based on positive results
• Pursue complementary acquisition opportunities
• Maintain systematic exploration across the portfolio

The company's dual-commodity strategy provides exposure to both the structural copper supply deficit and the continued strength in gold markets, positioning shareholders to benefit from multiple commodity cycles.

Next Steps: Multiple Catalysts Through Q1 2026

Immediate Catalysts:

• Nanadie assay results – January 2025
• Continued Nanadie drilling – Q1 2026
• Bluetooth Phase 4 drilling – Q1 2026 (2,000m programme)
• Exploration licence grants – unlocking additional targets

Medium-Term Opportunities:

• Resource expansion studies at Nanadie
• Fresh rock exploration at Edjudina Range
• Regional target testing across Yarri Project

The company reports that initial field observations from the Nanadie programme suggest mineralisation extends beyond current boundaries, though formal assay results remain pending. This preliminary indication, combined with systematic drilling coverage, positions the project for potential resource growth.

Investment Thesis: Dual-Metal Strategy in Proven Districts

Solstice Minerals presents a compelling investment proposition through its focused approach to Solstice Minerals copper-gold projects in Western Australia's established mining regions. The company's strategy combines:

Near-term Resource Growth Potential: Systematic drilling at Nanadie targeting significant expansion of an already substantial copper-gold resource in a supply-constrained copper market.

High-Grade Gold Discovery Pipeline: Multiple advanced prospects at Yarri, including Bluetooth's consistent wide intercepts and Edjudina Range's high-grade fresh rock system.

Strategic Location Advantages: Assets located within proven mining districts with established infrastructure and processing facilities within 100km.

Strong Balance Sheet: $14 million cash position providing operational flexibility and acquisition capability.

Copper Market Context

The global copper market faces mounting supply challenges as existing mines deplete whilst new discovery rates decline. Major copper deposits typically require 10-15 years from discovery to production, creating structural supply gaps that benefit developers with advanced projects.

Nanadie's near-surface mineralisation and established resource base position it advantageously in this environment. The project's 162,000 tonnes of contained copper represents meaningful scale in the Australian context, particularly given its accessibility and proximity to processing infrastructure.

Gold Exploration Upside

The Yarri Project's 1,600km² tenure covers prospective ground within the Eastern Goldfields' established mining corridors. Recent exploration success at Bluetooth and Edjudina Range demonstrates the property's potential to generate multiple discovery centres.

Gold exploration benefits from shorter development timelines compared to base metals, offering potential near-term value catalysts through resource definition and development studies. The project's location within 100km of established processing facilities further enhances development economics.
