OREAS 247 was prepared from a blend of high grade gold-bearing ore and barren metasediments. The gold ore was sourced from the central Victorian goldfields and is hosted within a metamorphosed turbidite sequence of interbedded sandstones, siltstones and shales. Gold mineralisation mainly occurs within disseminated arsenopyrite and pyrite ± stibnite-quartz zones.
Thirty-five commercial analytical laboratories participated in the program to certify:
Gold by fire assay;
Full ICP-OES and ICP-MS elemental suites by 4-acid digestion
