OREAS 504b
OREAS 504b was prepared from porphyry copper-gold ore and waste samples from a mine deposit located in central western New South Wales, Australia with the addition of a minor quantity of Cu-Mo concentrate.
OREAS 504b contains 110 certified values from the participation of twenty seven commercial analytical laboratories. The following methods were employed:
- Gold via 25-40g fire assay with AAS (20 labs) or ICP-OES (5 labs) finish;
- Gold via 15-50g aqua regia digestion with ICP-MS (8 labs), AAS (3 labs) or solvent extraction AAS finish (1 lab);
- Four acid digestion for full elemental suite ICP-OES and ICP-MS (25 laboratories);
- Aqua regia digestion for full elemental suite ICP-OES and ICP-MS (23 laboratories);
- Instrumental neutron activation analysis for Au on 1g subsamples to confirm homogeneity (1 laboratory).
