CAD$5.10 each

OREAS 317 has been prepared from a blend of barren black slate and various Zn-Pb-Ag ore and concentrate materials. This includes materials from the Dugald River, Black Star and Cannington deposits located in Northern Queensland, Australia.

Twenty-six commercial analytical laboratories participated in the program to certify:

  • Majors & base metals by oxidising fusion with X-ray fluorescence finish;
  • Loss on ignition at 1000° Celsius;
  • Total Sulphur by infrared combustion furnace or C/S analyser;
  • Full ICP-OES and MS elemental suites by peroxide fusion;
  • Full ICP-OES and MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl) digestion;
  • Full ICP-OES and MS elemental suites by aqua regia digestion.
