 Spectacular Fluorspar Discovery at Big Jim, Nevada
Key Points
  • Historically referenced Big Jim Fluorspar Lode rediscovered with massive fluorspar exposed at surface
  • Assays pending, but visual estimates indicate up to 98.6% CaF2 in the main lode and 60% CaF2 in the footwall breccia
  • Extensive system mapped over 220m with high-grade fluorspar at both ends, open along strike
Full Summary

OD6 Metals Limited (ASX: OD6) ('OD6' or 'the Company') has confirmed the rediscovery of the historically referenced high-grade Big Jim Fluorspar Lode at its Quinn Fluorspar Project, defining a significant new drill target within a growing district-scale fluorspar system. The Big Jim Fluorspar workings, noted in historic US Geological Survey reports, were located through targeted field reconnaissance, with an extensive high-grade system confirmed including massive fluorspar exposed at surface, plus a tunnel inferred to be the Big Jim lode. Visual estimates indicate the main lode contains up to 98.6% CaF2, while the footwall breccia contains up to 60% CaF2. The historic workings have been mapped out to over 220m in length, with high-grade fluorspar reported at both ends, indicating the system remains open along strike. Multiple rock samples have been collected for assay, and metallurgical samples have been taken for further testwork. The shallow westerly dip of the system provides a direct target for drilling to test the high-grade fluorspar mineralization extending underneath the lithocap. This discovery complements OD6's existing nearby Mammoth and Horseshoe fluorspar discoveries, further validating the company's ambition to become a US-based high-grade fluorspar developer.

Outlook

The rediscovery of the Big Jim Fluorspar Lode presents a third extensive fluorspar system on the Quinn Project, complementing the Mammoth and Horseshoe discoveries. OD6 plans to undertake further due diligence activities, including assay testing, detailed geological mapping, and soil geochemistry, to prioritize drill targets and initiate permitting for a maiden drilling program.
