OD6 Metals Limited (ASX: OD6) has announced the staking of additional exploration claims surrounding the Quinn Fluorspar Project in Nevada, USA, expanding its position within a historically productive fluorite district.
In my opinion, this adds genuine substance to the project, as it appears that the OD6 Metals management is working to establish it as the flagship project in the US and likely as the company's primary project as well. This is a great way to move the OD6 Metals journey while the long lead time projects such as Spinter Rock and Gulf Creek takes its time to mature.
The US looks like it is playing their geopolitical game to bring focus back to the US and most importantly, the companies are now getting funding and administrative support from the US government as well (something that the Australian Government should learn).
The newly secured ground captures interpreted strike extensions of several historical high-grade deposits including Mammoth, Spar, Big Jim, Rocket, Jumbo and Horseshoe, along with key structural corridors and extensive epithermal alteration zones considered prospective for fluorite mineralisation.
The expanded landholding also includes the Dresser epithermal alteration target, a large and largely untested zone hosted within favourable carbonate rocks that are known to host fluorite mineralisation elsewhere in the district.
Subject to the company exercising its option to acquire the Quinn Fluorspar Project, OD6 plans to undertake geological mapping, surface sampling, geochemical surveys and drill target generation as part of its due diligence program across the broader district-scale fluorite system.
About OD6 Metals Limited
For readers following the critical minerals sector, OD6 Metals Limited is a company developing a portfolio that spans rare earths, copper and fluorspar exploration assets.
The company’s flagship asset is the Splinter Rock Rare Earth Project in Western Australia, where a Mineral Resource Estimate confirmed a large clay-hosted rare earth deposit containing 119Mt @ 1,632ppm TREO (Indicated) and 563Mt @ 1,275ppm TREO (Inferred).
Beyond rare earths, OD6 has expanded into the fluorspar sector in the United States, where the company holds an option to acquire the Quinn Fluorspar Project in Nevada. Fluorspar (fluorite) is classified as a critical mineral in the United States, used in applications including semiconductors, batteries, hydrofluoric acid production and nuclear technologies.
This Samso News highlights a recent announcement where OD6 has expanded its claim position around the Quinn Fluorspar Project, securing ground interpreted to host extensions of several historic high-grade deposits.
OD6 Metals Secures Additional Ground Around Historic High-Grade Quinn Fluorspar Deposits in Nevada
OD6 Metals has announced the staking of additional exploration claims surrounding the Quinn Fluorspar Project in Nevada, USA, where the company currently holds an exclusive option to acquire a 100% legal and beneficial interest.
The newly staked claims expand the company’s footprint across the broader Quinn fluorite district, securing interpreted strike extensions of several historic deposits including Mammoth, Spar, Big Jim, Rocket, Jumbo and Horseshoe.
The claim expansion also captures structural corridors and carbonate host rocks known to host fluorite mineralisation, as well as a large untested alteration zone known as the Dresser target.

Highlights - OD6 Metals and the Quinn Fluorspar Project
Key points from the ASX announcement include:
OD6 Metals has staked multiple new exploration claims adjacent to the Quinn Fluorspar Project in Nevada.
The additional claims secure interpreted strike extensions of historical high-grade fluorspar deposits including Mammoth, Spar, Big Jim, Rocket, Jumbo and Horseshoe.
The expanded landholding captures extensive epithermal alteration zones considered prospective for fluorite mineralisation.
Several structural corridors and favourable carbonate host rocks have been secured within the new claims.
The newly staked ground includes the Dresser epithermal alteration target, interpreted as a potential centre of hydrothermal activity.
The project sits within Nevada, one of the world’s leading mining jurisdictions.
Management Commentary
OD6 Metals Managing Director Brett Hazelden commented that the new claim staking significantly strengthens OD6’s position within what the company believes to be an expansive district-scale fluorite system in Nevada.
According to the company, the expanded claims secure key structural corridors and epithermal alteration zones which may host additional fluorite mineralisation.
The claims also capture the Dresser alteration target, a large untested area located within favourable carbonate host rocks similar to those that host the existing fluorite deposits in the district.
Hazelden also noted that the United States currently imports 100% of its fluorspar supply, highlighting the strategic importance of developing domestic sources of the mineral.
Consolidating a District-Scale Fluorspar System
The Quinn project sits within a well-developed fluorite district hosted in carbonate rock sequences, where hydrothermal fluids associated with intrusive activity have produced fluorite-bearing veins, breccia pipes and replacement bodies.
Historical geological mapping indicates that the system extends beyond the currently known deposits, with epithermal alteration and structural corridors continuing across a broader area.
The new claims were staked to secure:
Strike extensions of known deposits
Large epithermal alteration zones
Favourable carbonate host rocks
Structural corridors associated with fluorite mineralisation

New Discovery Target Area – The Dresser Zone
A key focus of the claim expansion is the Dresser epithermal alteration target, located south of the main Quinn deposits.
This target hosts a large footprint of hydrothermal alteration within Pogonip limestone and Simonson dolomite units, which are geological formations known to host fluorite mineralisation elsewhere in the district.
Satellite hyperspectral data analysis has identified alteration signatures across the area, suggesting that the Dresser zone may represent another centre of hydrothermal activity within the broader fluorite system.
Near-term Milestones to Watch
OD6 Metals has outlined several activities as part of its due diligence and exploration program at the Quinn Fluorspar Project:
Surface rock chip and channel sampling
Verification of historic assay grades
Detailed geological mapping and structural interpretation
Soil geochemistry surveys
Geophysical studies and interpretation
Drill target generation across the district
Permitting for an initial drilling program
Metallurgical sampling and test work
These steps are designed to confirm historical mineralisation and define targets for future drilling programs.

Samso Concluding Comments
Does this look like OD6 Metals is making this a new flagship project? The establishment of new projects is not a bad idea to hedge your risk if your bank balance has the qualities to allow such options. My thoughts are that the commodity space is just positioning itself within a gold boom. If one takes a broader view of what is happening, I think the gold boom is a financial play, kind of the establishment of the new geopolitical financial scene t a new commodity equilibrium is being established which will require the new capital funding structure being created now.
I like what is happening with OD6 Metals as the latest acquisition may just be what the company needs to re-establish itself with a new image. The expansion of exploration claims around the Quinn Fluorspar Project increases OD6 Metals’ land position within a historically productive fluorite district in Nevada. The new claims secure extensions of known deposits and areas of epithermal alteration that may host additional fluorite mineralisation.
The claim staking also includes the Dresser alteration zone, which has been identified through satellite hyperspectral data as a large area of hydrothermal alteration hosted within carbonate rocks. These rock units are similar to those hosting existing fluorite deposits in the district.
The Quinn project sits within Nevada, a jurisdiction with a long history of mining and well-developed infrastructure. Historical production from the district and United States Geological Survey work have previously confirmed high-grade fluorspar mineralisation within the region.
Time and additional capital will be the key hurdles i will be looking for in 2026 as the company outlines a staged exploration program that includes geological mapping, geochemical sampling and verification of historic grades, followed by the generation of drill targets across the district. These activities form part of the company’s due diligence process as it evaluates the potential acquisition of the Quinn Fluorspar Project.
Market Implication - The Investor Lens
The market is liking the recent news as the share price chart is clearing showing (Figure 3) in morning trading as we write this blog on the 16th March 2026. As I have mentioned, I think it is a good idea to establish a "near production" play to the mix of projects.

This is not to say that there is production tones coming out from management but I like long terms proposition. Projects that of any substance is always long term. So lets wait for the Coffee with Samso with OD6 Metals at the end of March 2026.
