OD6 Metals (ASX: OD6) has unveiled an extensive epithermal alteration corridor at its Quinn Fluorspar Project.
Using EnMap satellite and NASA/JPL AVIRIS airborne hyperspectral data, the company identified an 8km corridor stretching from Dress Circle to Mammoth.
Further analysis revealed a 1.1km high-intensity alteration zone, effectively linking the Horseshoe and Jumbo prospects.
This suggests that previously known high-grade fluorspar occurrences are part of a larger, continuous mineralised system.
The Dress Circle area itself is highlighted as a 1.8km by 2km intense alteration zone, potentially indicating an intrusive source at depth.
The company estimates targets beneath the Lithocap to be between 20m to 40m beneath the surface.
Validating Previous Acquisitions
These remote sensing results provide strong validation for OD6 Metals' strategic land acquisitions made through new claim staking on March 15, 2026.
The company expanded its control over a district-scale epithermal alteration system.
The newly identified 8km corridor and the 1.1km high-intensity zone extend known high-grade fluorspar occurrences, such as those at Mammoth and Horseshoe.
Importantly, they include the previously underexplored Dresser epithermal alteration area.
This expansion significantly broadens the company's exploration footprint and enhances the potential for new discoveries within the project.
Sampling and Permitting Planned
With these promising remote sensing results in hand, OD6 Metals is now planning systematic, low-cost surface sampling.
This includes rock chip/channel sampling, channel mapping, and soil geochemistry to further define and prioritise drill targets.
Crucially, the company has initiated the permitting process for future drilling activities with the US Forest Service, as the project is located on Federal Land.
This upcoming phase of work aims to verify historic reports of very high-grade fluorspar, which have shown results greater than 40% CaF2 at Mammoth and Horseshoe, and historic rock chip results reaching up to 94% CaF2.
Strategic Context: Critical Fluorspar
Fluorspar is classified as a critical mineral for the United States, which currently has a 100% reliance on imports.
The high-grade potential of the Quinn Fluorspar Project aligns directly with the growing national need for a secure, domestic supply of this essential resource.
The project is strategically located approximately 220 km north of Las Vegas, Nevada, positioning it well within the US critical minerals supply chain.
Near-term success hinges on ground-truthing these targets through surface sampling and ultimately, the outcomes of future drilling, which will require regulatory approvals.
