Exploration Update from Solstice Minerals Ltd Delivers Strong Progress

Solstice Minerals Accelerates Multi-Project Exploration as 2025 Field Season Concludes

The exploration update from Solstice Minerals Ltd demonstrates significant momentum across its West Australian gold and copper portfolio, as the company concludes its successful 2025 field campaign. Furthermore, Solstice Minerals Limited (ASX: SLS) has positioned itself strategically with a 40Mt copper-gold resource at Nanadie while advancing multiple high-grade gold discoveries. This comprehensive approach positions the company well for 2026 catalysts.

With $14 million in cash and no debt, Solstice maintains strong operational flexibility to capitalise on drilling results. Additionally, the company continues to pursue value-enhancing opportunities across its 1,730km² of strategic tenure in proven mining districts.

Nanadie Copper-Gold Project Shows Expansion Potential

In this exploration update from Solstice Minerals Ltd, the flagship Nanadie project continues to demonstrate the scale potential that attracted the company's acquisition earlier this year. The 5,000m Phase 1 RC drilling programme has completed 13 holes for 3,619m, with holes consistently achieving good sample quality beyond 300m depth.

Current Nanadie Resource Highlights:

• 40Mt Inferred Resource containing 162,000t copper and 130,000oz gold
• Near-surface mineralisation up to 150m wide and 900m long
• Shallow oxide profile ideal for potential open-pit development
• Located within 130km² of 100%-owned tenure in the Murchison Goldfields

According to the quarterly update, initial field observations indicate the mineralised system has significant room for expansion. However, drilling is targeting largely unconstrained deposit margins, which suggests considerable upside potential. The company plans a comprehensive update in early 2026 once field observations are compiled, with first assays expected in January.

"We are working toward expanding an already significant body of copper-gold mineralisation lying hidden and only partly defined below shallow soil cover," CEO Nick Castleden commented.

Bluetooth Gold Prospect Delivers Consistent High-Grade Results

The exploration update from Solstice Minerals Ltd outlined how the Bluetooth Gold Prospect continues to build a compelling case for near-surface gold development. Furthermore, 2025 RC drilling has returned multiple thick, high-grade intersections over a 900m strike length.

Key Bluetooth Intercepts from 2025:

The discovery shows excellent geometry for eventual open-pit extraction, with thick, shallowly-dipping oxide gold panels. These characteristics would offer processing advantages in an active mining district northeast of Kalgoorlie. In addition, a 2,000m RC programme comprising 22 holes is scheduled for Q1 2026 to further define the mineralisation and test down-plunge extensions.

Early signs of mineralisation extending into fresh rock (7m @ 1.38g/t Au EOH) suggest potential for depth extensions beyond the current oxide focus.

Edjudina Range Confirms High-Grade Gold System

The Edjudina Range discovery has evolved from reconnaissance target to confirmed high-grade gold system. Moreover, recent results have validated the presence of significant structures in fresh bedrock.

Edjudina Range 2025 Highlights:

• 5 of 7 RC holes intersected >1g/t Au in fresh rock
• 2m @ 11.10g/t Au (including 1m @ 20.90g/t Au) confirms high-grade potential
• 2m @ 5.79g/t Au (including 1m @ 10.87g/t Au) demonstrates system consistency
• 10m @ 0.47g/t Au to end-of-hole in recent aircore drilling
• 1km+ strike length of gold anomalism identified

Recent aircore drilling has extended anomalous gold results across the central 500m strike of the discovery area. Consequently, results up to 10m @ 0.47g/t Au to end-of-hole confirm broad zones of gold anomalism in weathered profiles.

The gold system shows classic signatures including quartz veining, carbonate alteration, and arsenic pathfinder anomalism in deformed rocks. These indicators represent signatures of an active bedrock gold system with regional scale potential.

Understanding Mineral Resource Categories

Inferred Resources represent the lowest confidence category of mineral resources under the JORC Code. However, they require sufficient drilling to establish geological continuity, though with limited confidence in grade and tonnage estimates.

For investors, Inferred Resources indicate:

• Exploration potential – sufficient evidence exists for further investigation
• Investment thesis support – provides foundation for development studies
• Expansion opportunities – typically grow through additional drilling

The progression from Inferred to higher-confidence categories (Indicated and Measured) requires systematic drilling programmes. For instance, this is exactly what Solstice is now executing at Nanadie through its current campaign.

Strategic Pipeline Expands Through Tenure Applications

Solstice continues building its portfolio through strategic tenure applications across both the Yarri and Ringlock projects. Furthermore, the company has secured applications over proven targets with historical results including:

Pipeline Targets Secured:

• Webb Find: 12m @ 3.80g/t Au, 8m @ 2.74g/t Au, 6m @ 3.85g/t Au
• Wallbrook West: 23m @ 2.80g/t Au
• Stewart Well: 10m @ 1.06g/t Au with wide anomalous zones

These targets are primed for immediate RC testing once permitting is completed. Consequently, they provide a ready pipeline of drill-ready prospects to complement current operations.

Investment Thesis: Multi-Asset Strategy in Proven Districts

Solstice's investment appeal centres on its strategic positioning across multiple high-quality assets in established mining districts. Additionally, the company benefits from strong financial capacity to execute systematic exploration programmes across its portfolio.

Key Investment Drivers:

1. Nanadie expansion potential – significant copper-gold resource with unconstrained margins
2. Near-surface gold discoveries – Bluetooth and Edjudina Range offer development optionality
3. Proven districts – all projects located within 150km of Kalgoorlie in active mining areas
4. Strong balance sheet – $14M cash provides multi-year exploration funding
5. Systematic approach – disciplined drilling programmes targeting resource expansion

The combination of an established resource base at Nanadie with multiple early-stage discoveries provides both near-term catalyst potential and longer-term development optionality.

What Makes This Exploration Update from Solstice Minerals Ltd Significant?

Solstice has positioned itself as a well-funded exploration company with multiple shots at discovery success across two of Western Australia's most endowed mineral provinces. Furthermore, the company's systematic approach to resource expansion at Nanadie, combined with aggressive exploration of its gold portfolio, creates multiple pathways for value creation.
