OREAS 313 is a replacement of the OREAS 136. It was prepared from a blend of barren and ore grade zinc-lead-silver materials sourced from Mount Isa (Glencore) George Fisher mine, Mt Isa, NW Queensland, Australia. The mineralisation style is sediment-hosted ‘SEDEX’ Zn-Pb-Ag within the Urquart Shale Formation of the Mount Isa Group. This Group is a 5 km thick sequence, composed predominantly of Mesoproterozoic carbonate siltstones, mudstones and shales, metamorphosed to greenschist facies. The Zn-Pb-Ag orebodies are concordant with carbonaceous dolomitic sediments and comprised of sphalerite and galena with pyrite and pyrrhotite. The following methods were undertaken:
