OD6 aims to position itself as an emerging supplier of strategically important critical minerals required for next-generation industrial, defence and energy technologies. Quinn Fluorspar Project – Nevada, USA OD6 is advancing the Quinn Fluorspar Project located in Nevada, USA, one of the world’s premier mining jurisdictions and currently ranked second globally in the Fraser Institute 2025 Mining Attractiveness Index. Quinn hosts multiple high-grade fluorspar deposits across 226 mining claims (4,670 acres / 1,890ha) including Horseshoe, Mammoth and Big Jim, with historical drilling, channel sampling and testwork confirming significant high-grade mineralisation and potential for both Metspar and premium Acidspar products.
