OD6 TO ACQUIRE ULTRA HIGH GRADE USA FLUORSPAR PROJECTS – 4th March 2026 - view the announcement
USA FLUORSPAR ACQUISITION PRESENTATION - 5th March 2026 - view announcement
The acquisition of the Quinn Fluorspar Project introduces OD6 Metals Limited to the fluorspar market, a mineral classified as critical across multiple jurisdictions including the United States, Australia, the European Union, Canada, and Japan. Fluorspar is the primary source of fluorine, an element used across semiconductor manufacturing, advanced batteries, nuclear fuel processing, and defence technologies.
The project is located in Nevada, a globally recognised mining jurisdiction with established infrastructure and regulatory frameworks supportive of mineral development. The United States is currently fully reliant on imported fluorspar, creating potential strategic interest in domestic supply sources.
From an investor's viewpoint, OD6 Metals Limited is now exploring emerging technology supply chains and national security issues. With the market volatility, OD6 Metals Limited look likes its managing portfolio risks.
The acquisition also brings in a project with historically high-grade fluorspar occurrences and past small-scale production, offering an initial geological framework for resource delineation.
2. About OD6 Metals Limited
OD6 Metals Limited is an Australian-listed exploration company focused on critical minerals. The Company is building a portfolio of projects targeting commodities considered important for energy transition and advanced technologies.
Its current asset portfolio includes:
The Quinn Fluorspar Project in Nevada, United States
Rare earth projects such as Splinter Rock
Copper exploration assets including Gulf Creek
The Quinn acquisition adds fluorspar exposure to the company’s portfolio and provides a potential pathway into the United States critical minerals supply chain.
3. Introduction
The March 2026 ASX presentation outlines the proposed acquisition of the Quinn Fluorspar Project located in Nevada, USA.
The project hosts multiple historical fluorspar prospects with reported high-grade mineralisation from previous sampling and small-scale mining activity. The OD6 Metals Limited presentation describes the geological setting, historical exploration results, acquisition structure, and planned exploration activities.
Fluorspar deposits at Quinn occur within carbonate host rocks affected by hydrothermal alteration linked to Tertiary volcanism. Mineralisation is interpreted to occur in veins, breccias, and replacement bodies within limestone and dolomite units.
OD6 Metals Limited intends to verify historical data and undertake systematic exploration with the aim of defining a JORC-compliant mineral resource.

About Fluorspar
Fluorspar (CaF₂) is the primary mineral source of fluorine and is widely used in semiconductor manufacturing, lithium battery chemistry, nuclear fuel processing, and advanced materials production.
4. Highlights
OD6 Metals Limited has secured an option to acquire the Quinn Fluorspar Project in Nevada, USA.
Fluorspar (CaF₂) is classified as a critical mineral by multiple jurisdictions including the United States.
The United States currently relies entirely on imported fluorspar supply.
Historical exploration identified high-grade mineralisation including:
Up to 94% CaF₂ in rock samples
Channel samples up to 45% CaF₂.
The project contains several prospects including Mammoth, Horseshoe, Spar Mine, and Big Jim.
Historic production at the Horseshoe deposit produced approximately 26,000 tonnes from shallow open pits.
Acquisition structure involves staged payments with an initial A$75,000 option payment and additional milestone-based payments tied to exploration success.
5. Management Commentary
The presentation outlines OD6 Metals Limited’ view that the Quinn Fluorspar Project represents a district-scale high-grade fluorspar system with multiple prospects and exploration pathways.
The company highlights that fluorspar plays an essential role in industries such as semiconductor manufacturing, batteries, nuclear fuel processing, and defence systems. Fluorine derived from fluorspar is used in plasma etching for semiconductor fabrication and in lithium battery electrolyte chemistry.
Management also notes that the United States’ reliance on imported fluorspar creates a strategic context for domestic supply development.
6. Near-Term Milestones to Watch
Planned exploration and development activities include:
Surface rock chip and channel sampling programs
Verification of historical exploration data
Geological mapping and structural interpretation
Soil geochemistry surveys
Geophysical investigations
Development of drilling programs to test mineralisation
Permitting processes for initial drilling programs
Metallurgical test work planning
These activities aim to establish a geological model and progress toward resource delineation.

8. Samso Concluding Comments
The Quinn Fluorspar acquisition introduces OD6 Metals Limited into the fluorspar sector, a mineral category receiving increasing attention due to its role in advanced industrial technologies. Fluorspar is the primary source of fluorine, which is used in semiconductor chip fabrication, lithium battery chemistry, nuclear fuel processing, and various defence applications. The United States’ current reliance on imported supply creates a strategic context for domestic exploration projects.
Geologically, the project area contains multiple occurrences of fluorspar mineralisation hosted within carbonate rocks affected by hydrothermal activity. The Mammoth (Figure 2) and Horseshoe (Figure3) prospects represent the most advanced targets identified from historical work. These prospects host mapped zones of mineralisation interpreted to extend beneath shallow cover and along structural controls.
Figure 2: Mammoth Deposit Geological Section (OD6 Metals Limited)
Historic sampling from these areas indicates high grades in both rock chips and channel samples. At Mammoth, surface sampling has returned results including 10.7 metres at 44.9% CaF₂ and 15.2 metres at 48% CaF₂, suggesting significant concentrations of mineralisation within breccia-hosted systems. At Horseshoe, historical mining extracted approximately 26,000 tonnes of fluorspar from shallow pits, indicating that mineralisation reaches the surface in places.

The project also includes several additional prospects such as Spar Mine and Big Jim, where sampling has reported fluorspar grades exceeding 70–90% CaF₂ in veins and channel samples. These occurrences indicate a broader mineralised district that may contain multiple exploration targets.
From a development perspective, the company plans to begin with systematic field programs to confirm historical results before advancing toward drilling. If exploration confirms continuity and grade, the next stage would involve defining a JORC-compliant resource. The staged acquisition structure ties major payments to exploration success, aligning financial commitments with geological progress.
