OREAS 508
SKU: 508
OREAS 508 was prepared from a blend of porphyry copper-gold ore, barren
granodiorite and a minor quantity of Cu-Mo concentrate. The ore was sourced from
Northparkes Mine 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).
