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:

  • Gold by fire assay;
  • Gold by 15-50g aqua regia digestion;
  • Gold by 5-200g cyanide leach;
  • Full ICP-OES and ICP-MS elemental suites by 4-acid digestion;
  • Full ICP-OES and ICP-MS elemental suites by aqua regia digestion.
