OREAS 353 is a certified reference material (CRM) prepared from a Pb-Ag concentrate sample sourced from South32 Ltd’s Cannington mine plant. The stratabound, metasediment hosted (Broken Hill Type) deposit is located ~200 kms south-east of Mount Isa in north-west Queensland, Australia. The major sulphides occur as argentiferous galena and sphalerite with subordinate magnetite-pyrrhotite and minor marcasite and arsenopyrite-lollingite-chalcopyrite. OREAS 353 is certified for:
Lead by ethylenediamminetetraacetic acid (EDTA) with titration finish
Silver by reduced charge, fire assay with gravimetric finish
Moisture (H2O-) at 105°C by thermogravimetry
Full ICP-OES & MS elemental suites by 4-acid digestion
Full ICP-OES elemental suite by peroxide fusion
S and C by infrared combustion furnace
