OREAS 319
SKU: 319
OREAS 319 is a replacement of the OREAS 139. It was prepared from a blend of
barren and ore grade zinc-lead-silver materials sourced from Mount Isa
(Glencore) George Fisher mine, Mt Isa, NW Queensland, Australia. The
mineralisation style is sediment-hosted ‘SEDEX’ Zn-Pb-Ag within the Urquart
Shale Formation of the Mount Isa Group. This Group is a 5 km thick sequence,
composed predominantly of Mesoproterozoic carbonate siltstones, mudstones and
shales, metamorphosed to greenschist facies. The Zn-Pb-Ag orebodies are
concordant with carbonaceous dolomitic sediments and comprised of sphalerite and
galena with pyrite and pyrrhotite. The following methods were undertaken:
4-acid (HNO3-HF-HClO4-HCl) digestion with full suite ICP-OES and ICP-MS
elemental packages
Aqua regia digestion for full elemental suite ICP-OES and ICP-MS
Lithium borate fusion whole rock analysis package by X-ray fluorescence
Thermogravimetry: Loss on Ignition (LOI) at 1000 °C
Lithium borate or sodium peroxide fusion with full suite ICP-OES and
ICP-MS elemental packages
C and S by infrared combustion furnace/CS
analyser
