Satellite Data Reveals 8km Fluorspar Alteration Zone at Quinn Project

• 8km-long epithermal alteration system identified via satellite and airborne hyperspectral data
• High-intensity alteration zones link known prospects Horseshoe, Jumbo, and Mammoth
• Dress Circle anomaly suggests possible intrusive mineral source at depth
• Project located in US critical minerals jurisdiction with strategic supply implications
• Upcoming surface sampling, geological mapping, and drill targeting planned

Advanced Remote Sensing Unlocks New Potential

OD6 Metals Limited has taken a significant step forward in its exploration of the Quinn Fluorspar Project in Nevada, unveiling an extensive 8-kilometre epithermal alteration corridor. This discovery, made possible through cutting-edge satellite and airborne hyperspectral imaging, dramatically expands the geological understanding of the project area and hints at a mineralised system far larger than previously recognised.

The use of EnMap satellite imagery combined with NASA's AVIRIS airborne hyperspectral data allowed the identification of key alteration minerals such as pyrophyllite, alunite, dickite, and muscovite. These minerals are indicative of hydrothermal fluid activity, which is closely associated with fluorspar mineralisation. Notably, the alteration system connects historically known prospects including Horseshoe, Jumbo, and Mammoth, suggesting a continuous mineralised corridor rather than isolated deposits.

Strategic Importance of the Quinn Fluorspar Project

Fluorspar, or calcium fluoride, is a critical mineral essential for a range of high-tech applications including battery technologies, AI chip manufacturing, nuclear fuels, and aerospace. The United States currently imports 100% of its fluorspar supply, with a heavy reliance on China. OD6’s Quinn Project, situated approximately 220 kilometres north of Las Vegas and near the US Strategic Minerals Reserve at Hawthorne, Nevada, could play a pivotal role in bolstering domestic supply chains.

Historical mining at Quinn dates back to the 1950s, but exploration has been limited since. The new remote sensing data reveals alteration zones over 8 kilometres long, with intense zones exceeding 1 kilometre in strike length. The Dress Circle anomaly, a 2km by 1.8km zone of intense alteration, is particularly intriguing as it may indicate an intrusive source at depth, a classic hallmark of significant epithermal mineral systems.

Next Steps and Exploration Outlook

OD6 Metals is preparing to advance from remote sensing to on-ground exploration. The company plans systematic surface rock chip and channel sampling to validate historic assay results, detailed geological mapping, soil geochemistry, and structural interpretation. These efforts will feed into prioritising drill targets and commencing permitting for initial drilling programs.

Managing Director Brett Hazelden emphasised the confidence these findings bring to the company’s targeting strategy, noting the potential for new discoveries and scale beyond historic workings. The integration of modern remote sensing technologies with traditional exploration techniques positions OD6 to unlock value in a critical mineral sector that is increasingly strategic on a global scale.

While no drilling results have yet been reported, the scale and intensity of alteration mapped provide a compelling case for further investment and exploration. The project’s location in a top-tier mining jurisdiction and proximity to strategic reserves further enhances its appeal.

Bottom Line?

OD6 Metals’ remote sensing breakthrough at Quinn sets the stage for a potentially transformative fluorspar discovery in a critical US supply region.

Questions in the middle?

• How will upcoming surface sampling results confirm the extent and grade of mineralisation?
• What are the timelines and challenges for securing drilling permits on federal land?
• Could the Dress Circle anomaly represent a significant intrusive source driving mineralisation?
