OREAS L15b

OREAS L15b was prepared from a blend of high-grade gold-bearing ore, barren metasediments and basalt. The gold ore was sourced from the Agate Creek Gold Mine in Queensland, Australia. Agate Creek’s gold deposits are hosted mainly in Permian volcanic rocks (rhyolite and andesite) of the Agate Creek Volcanic Group. The mineralisation is characterised predominantly by a low-sulphidation epithermal gold system, with gold occurring in quartz-chalcedony veins, stockworks and breccias developed in and around volcanic dykes and shallowly dipping faults. Thirty-nine commercial analytical laboratories participated in the program to certify Gold by lead collection fire assay.
