OREAS 266 was prepared from a blend of high grade gold-bearing ore, barren sedimentary rocks and barren basaltic scoria. The gold ore was sourced from the Agate Creek Gold Project located in the Etheridge Goldfield of northern Queensland, Australia. The project is hosted within a metamorphosed turbidite sequence of interbedded sandstones, siltstones and shales. Epithermal and mesothermal gold mineralisation occurs within quartz veining, stockworks and breccias associated with Permian felsic volcanic units and Proterozoic batholith. Twenty-two commercial analytical laboratories participated in the program to certify:
|Analyte||Indicative Value||1SD||Expanded Uncertainty Low||Expanded Uncertainty High||Method|
|Au, Gold (ppm)||8.23||TBD||TBD||TBD||Pb Fire Assay|
