OREAS 922b
SKU: 922b
OREAS 922b was prepared from material from the CSA mine located near the town
of Cobar in central western New South Wales, Australia. The copper ore body is
hosted by the Early Devonian CSA Siltstone, a thinly bedded turbiditic sequence
of carbonaceous siltstones and mudstones with minor coarser units. The CSA
Siltstone is part of the Cobar Supergroup, consisting of lower syn-rift
sediments and upper post-rift sag phase sediments. The mineralisation is
structurally controlled and confined to a number of steeply dipping bodies
within a major shear zone on the eastern margin of the Early Devonian Cobar
Basin. It is characterised by low-grade greenschist alteration and epigenetic
low-grade mineralisation enveloping higher-grade shoots of vein complexes or
sub-massive to massive sulphides. The sulphides include chalcopyrite,
pyrrhotite, pyrite, sphalerite, galena, bornite and cubanite. Iron-rich chlorite
and silica are prominent alterations in the siltstone host. The certification
program includes:
4-acid digestion with full suite elemental packages by ICP-OES and ICP-MS
finish
Aqua regia digestion for full elemental suite by ICP-OES and ICP-MS finish
Lithium borate fusion whole rock analysis package by X-ray fluorescence
finish
Thermogravimetry: Loss on Ignition (LOI) at 1000 °C
Lithium borate or sodium peroxide fusion with full suite elemental
packages by ICP-OES and ICP-MS finish
C and S by infrared combustion furnace/CS analyser
