OD6 Metals Reports Continuous High-Grade Fluorspar at Quinn Project with 12m at 40.8% CaF2

High-Grade Fluorspar Confirmed at Mammoth Prospect

OD6 Metals Limited (ASX:OD6) has reported encouraging results from channel sampling at the Mammoth Prospect, part of its Quinn Fluorspar Project in Nevada, USA. The sampling returned a continuous 12-metre interval averaging 40.8% calcium fluoride (CaF2), with a peak grade of 54.0% CaF2 over one metre. This breccia replacement style mineralisation demonstrates both high grade and strong continuity across the exposed outcrop.

Managing Director Brett Hazelden highlighted the significance of these results, noting that the average grade places the system among the higher-grade fluorspar deposits globally. The channel sampling, conducted at one-metre intervals, provides a more representative and reliable indication of grade continuity than previous selective rock chip samples.

Large-Scale Mineralised System with Untested Potential

The mineralised breccia system at Mammoth extends over a mapped area of approximately 9,000 square metres and up to 60 metres in width. Geological indicators suggest that the surface expression is representative of a potentially larger mineralised system extending at depth and along strike. Importantly, the channel sampling covers only a fraction of the known mineralised area, leaving significant portions untested.

These findings validate historic high-grade sample results from the 1960s and more recent rock chip assays, confirming grade reliability and consistency within the large-scale system. The project area includes other fluorspar occurrences, such as the Horseshoe Project, with historic rock chip results reportedly reaching up to 94% CaF2.

Strategic Importance Amid US Fluorspar Supply Reliance

The Quinn Fluorspar Project is located approximately 220 kilometres north of Las Vegas, Nevada, and about 300 kilometres by road from the US Strategic Minerals Reserve at Hawthorne. The United States currently imports 100% of its fluorspar consumption, with a significant portion sourced from China. Fluorspar is classified as a critical mineral by the US Geological Survey due to its applications in advanced battery technologies, AI semiconductor chip etching, nuclear fuel processing, and aerospace and defence sectors.

In a broader market context, OD6 Metals has been advancing exploration at Quinn with systematic surface sampling, geological mapping, and drill targeting, following the launch of its first modern exploration program in decades. These recent channel sampling results build on earlier findings, including high-grade rock chip assays up to 53.2% CaF2 at Mammoth, confirming the potential for a broader mineralised system OD6 Metals Confirms High-Grade Fluorspar Up to 53.2% CaF2 at Mammoth, Nevada with Expansion Potential.

Next Steps in Exploration and Development

OD6 Metals plans to expand its due diligence with further systematic channel and rock chip sampling, detailed geological and structural mapping, soil geochemistry programs, and drill target identification. The company also intends to initiate permitting processes for maiden drilling and progress metallurgical testwork planning. These steps aim to validate and replicate historic high-grade results and better define the resource potential of the Quinn Fluorspar Project.

Channel sampling results were independently assayed by ALS Global laboratories, with quality control procedures confirming the reliability of the data. The sampling was conducted under the supervision of Dr Darren Holden, a Competent Person as defined by the Australasian Code for reporting exploration results.
