West Cobar Metals Secures Historic Acid-Grade Baxter Fluorspar Project in Nevada

West Cobar Metals Enters Nevada Fluorspar Market with Historic High-Grade Acquisition

West Cobar Metals Limited (ASX: WC1) has announced the West Cobar Metals Baxter Fluorspar Project acquisition in Nevada, USA. The historic high-grade fluorspar asset documented production of approximately 200,000 tonnes of acid-grade concentrate grading 97–98% CaF₂ between 1928 and 1957. The deal includes a $1,051,146 placement to fund due diligence, exploration, and broader portfolio activities, marking the company's entry into the US critical minerals market as domestic fluorine supply chains face increasing scrutiny.

A Historic Asset in a Premier Jurisdiction

The Baxter Fluorspar Project sits in south-west Nevada, approximately 150km east-southeast of Reno, on 51 contiguous BLM-registered claims covering roughly 4.3km² of public land. Nevada is consistently ranked among the world's leading mining jurisdictions, offering established infrastructure, low sovereign risk, and clear permitting pathways.

The project's crown jewel is the Kaiser Mine, which operated from 1928 to 1957 and generated meaningful production history before modern exploration techniques existed. A second historical working, the Spar Dome Mine, also sits within the claim boundary and has notably never been drill-tested.

The mineralisation at Kaiser occurs within structurally controlled fluorite-bearing vein systems associated with faulting, silicification, and brecciation. Historical underground development over 680 metres of strike suggests strong continuity of mineralisation along strike and at depth, with potential for extensions that remain completely untested by modern methods.

"Historical production of approximately 200,000 tonnes of fluorspar including a premium acid-grade concentrate provides a strong platform for exploration potential. Much of the district has not been evaluated using modern exploration techniques. We believe there is substantial opportunity to identify extensions to known mineralisation and potentially discover additional fluorite-bearing structures across the project area." — Managing Director Matt Szwedzicki

What Is Acid-Grade Fluorspar and Why Does It Matter?

Acid-grade fluorspar represents the highest-purity commercially produced form of fluorspar, typically grading 97% or more calcium fluoride (CaF₂). It serves as the primary feedstock for producing hydrofluoric acid (HF), which sits at the foundation of an enormous range of industrial and high-technology processes.

Without acid-grade fluorspar, hydrofluoric acid cannot be produced. Consequently, without hydrofluoric acid, industries cannot manufacture semiconductors, process lithium-ion battery materials, enrich nuclear fuel, or produce advanced refrigerants.

This distinction matters significantly for investors. Many fluorspar projects produce lower-purity "metallurgical-grade" material used primarily in steel production. Acid-grade fluorspar, however, commands a meaningfully higher price premium and sits at the critical junction of several high-growth industrial value chains simultaneously.

The Baxter Project's documented historical production of acid-grade concentrate grading 97–98% CaF₂ indicates that the deposit has the geological character capable of generating a premium product. Furthermore, West Cobar intends to build on this foundation through modern exploration.

Technical Glossary

• CaF₂ (Calcium Fluoride): The mineral compound measured to determine fluorspar grade and purity
• Acid-Grade Fluorspar: Fluorspar grading ≥97% CaF₂, used to produce hydrofluoric acid and downstream fluorochemicals
• Metallurgical-Grade Fluorspar: Lower-purity material (typically 60–85% CaF₂) used in steel and aluminium smelting
• NSR (Net Smelter Return) Royalty: A royalty calculated as a percentage of gross revenue from metal or mineral sales, less transportation and refining costs
• BLM (Bureau of Land Management): The US federal agency that administers public land, including unpatented mining claims
• Hydrothermal Vein System: Mineral deposits formed by hot mineral-rich fluids moving through fractures and faults in the earth's crust

The Strategic Case: Why Fluorspar, Why Now, Why Nevada

Fluorspar's classification as a critical mineral by the United States, Australia, and the European Union reflects growing awareness that western industrial supply chains face dangerous exposure to a single dominant supplier. China currently controls the majority of global fluorspar supply, whilst the United States has virtually no meaningful domestic production despite widespread industrial use.

The end-use applications driving demand growth represent structural rather than speculative or cyclical trends:

1. Semiconductors: Hydrofluoric acid is essential in chip etching and cleaning processes
2. Lithium-ion batteries: Fluorine compounds are used in electrolytes and cathode materials
3. Nuclear fuel processing: Uranium hexafluoride (UF₆) enrichment requires significant fluorine inputs
4. Defence and aerospace: High-performance fluoropolymers are used in specialised equipment and coatings
5. Advanced refrigerants: New-generation low-GWP refrigerants require fluorine chemistry
6. Steel and aluminium: Fluorspar serves as a fluxing agent in metal production

This demand profile spans defence, energy transition, and advanced manufacturing simultaneously. These sectors increasingly treat supply security as a national priority.

For West Cobar, acquiring a Nevada-based, historically proven acid-grade fluorspar project positions the company at the intersection of all these demand vectors, on US soil, in a first-tier mining jurisdiction.

Acquisition Structure: Low-Cost Entry with Defined Upside

The transaction is structured to minimise upfront capital at risk whilst preserving significant potential upside for WC1 shareholders.

The 30-day due diligence period represents an important investor consideration. West Cobar retains the ability to assess the full technical and commercial picture before completing the transaction, with plans to undertake ground inspection, surface sampling, and detailed technical review of historical mine data during this period.

The cash consideration is entirely in shares, meaning the primary financial exposure is the A$60,000 exclusivity fee. This represents a lean entry point for a project with documented acid-grade production history.

The $1,051,146 Placement: Funded for Action

To support the acquisition and advance activities across its portfolio, West Cobar has successfully completed a share placement, raising $1,051,146 gross at $0.017 per share. This represents a 15% discount to the last closing price and a 20% discount to the 15-day VWAP.

The placement was lead managed by Xcel Capital Pty Ltd, which will receive a management fee of up to 6% of gross proceeds and 5,000,000 unlisted options at an exercise price of $0.04, expiring 15 May 2028.

Funds are earmarked across the portfolio with specific allocations for:

• Due diligence and initial exploration at the Baxter Fluorspar Project
• Flowsheet and recovery optimisation and testwork at the Salazar Critical Minerals Project
• Continued exploration at the Cobar West Project
• General working capital

Exploration Roadmap: What Comes Next?

The Baxter Project has seen only limited modern exploration. No systematic geophysical surveys, minimal drilling relative to the known system, and significant untested strike length create a compelling exploration opportunity that requires methodical execution.

West Cobar has outlined a clear phased approach.

Immediate (Due Diligence Phase)

• Ground inspection and surface sampling
• Compilation and digitalisation of historical mine records
• Tenure verification and technical data review

2026/27 Financial Year Program

1. Detailed geological and structural mapping
2. Rock chip and channel sampling programmes
3. Verification of historical drill results
4. Geophysical surveys (where appropriate)
5. Drill target generation
6. Drill testing of priority targets
7. Metallurgical testwork

The exploration thesis is well-defined. In addition, the company is targeting three distinct opportunity types:

• High-grade vein extensions along strike and at depth from known Kaiser Mine workings
• Fracture and breccia-hosted mineralisation across the broader 3km corridor
• New fluorite-bearing structures across the district, including the undrilled Spar Dome Mine area

The 3km mineralised corridor hosting multiple historical workings, with most of it never subjected to systematic modern methods, represents a meaningful exploration pipeline before a drill bit turns.

Portfolio Context: A Diversified Critical Minerals Platform

The West Cobar Metals Baxter Fluorspar Project acquisition in Nevada slots into an existing portfolio of Australian and now American critical minerals assets.

The addition of a US-based fluorspar project adds geographic diversification, commodity diversification, and direct exposure to the North American fluorine supply chain. This market is distinct from Australian and European supply dynamics and increasingly driven by onshoring priorities.

Why Investors Should Watch West Cobar Closely

West Cobar has made a low-cost entry into a high-profile critical minerals commodity at a moment of genuine strategic relevance. Several factors combine to make this a story worth following:

• Proven production history: ~200,000 tonnes of acid-grade fluorspar from the Kaiser Mine provides geological confidence that the system is capable of generating premium product
• Significant exploration upside: The 3km corridor hosting multiple historical workings has seen virtually no modern exploration. The system is open along strike, across strike, and at depth
• Premier jurisdiction: Nevada's established mining framework provides a low-risk operating environment for US-based exploration activity
• Lean deal structure: A$60,000 non-refundable exclusivity fee limits downside during the due diligence period, with the balance payable in shares upon completion
• Well-funded balance sheet: The $1,051,146 placement provides capital to advance Baxter alongside the existing Australian portfolio
• Diversified critical minerals portfolio: Copper, antimony, scandium, REEs, and now fluorspar provide exposure across multiple critical minerals themes simultaneously
