| Description: OREAS 139 has been prepared from a blend of barren and ore grade SEDEX Type Zn-Pb-Ag materials sourced from the Dugald River deposit located in the Mt Isa Inlier, ~65km north-west of Cloncurry in north-west Queensland, Australia. The mineralisation style is dominated by sphalerite and galena with a gangue of graphitic slate, pyrrhotite and pyrite. The deposit is hosted within a sequence of upper greenschist to amphibolite facies metamorphic rocks consisting quartzite, schists, slates and dolomite.
