OREAS 503e
SKU: 503e
OREAS 503e was prepared from a blend of porphyry copper-gold ores, barren
granodiorite and a minor quantity of Cu-Mo concentrate. The ores were sourced
from both the Cadia Mine and Northparkes Mine. Both mines are located in
the central west of New South Wales, Australia. The barren
granodiorite was sourced from the mafic, S-Type, Late Devonian Bulla
Granodiorite complex located in northern Melbourne, Australia.
Twenty-two commercial analytical laboratories participated in the program to
certify the elements shown below. The following methods were employed:
Gold by 15-50g fire assay with AAS (17 laboratories) or ICP-OES (4
laboratories) finish;
Gold by 10-50g aqua regia digestion with ICP-MS finish (10 laboratories)
and AAS (5 laboratories) finish;
4-acid digestion for full elemental suite ICP-OES/MS finish (up to 19
laboratories depending on the element)
Aqua regia digestion for full elemental suite ICP-OES/MS and AAS finish
(up to 21 laboratories depending on the element).
Gold by instrumental neutron activation analysis (INAA) on 20 x 85mg
subsamples was undertaken to confirm homogeneity (at ANSTO, Lucas Heights,
Australia).
