OREAS L11b was prepared from a blend of high grade gold ore, barren metasediments and basalt. The 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. Twenty-eight commercial analytical laboratories participated in the program to certify Gold by fire assay.
