OREAS 554b
primary
dolomitic shale
structurally-controlled sediment-hosted
OREAS 554b
SKU: 554b
OREAS 554b was prepared from copper-cobalt sulphide ore samples sourced from
MMG’s Kinsevere Mine blended with barren black slate and a minor addition of
cobalt concentrate. The Kinsevere Mine is located in the Haut-Katanga province
about 30 km from Lubumbashi in the south-east of the Democratic Republic of the
Congo (DRC). The hypogene mineralisation at Kinsevere occurs as stratabound,
veins and breccias consisting of mainly chalcopyrite, carrolite, bornite and
occasionally pyrite and chalcocite, hosted within the Mine series carbonaceous
shales, siltstones, and dolomites of the Roan Group belonging to the Katangan
Supergroup stratigraphy.
Thirty analytical laboratories participated in the program using the
following methods:
Lithium borate fusion whole rock analysis package by X-ray fluorescence
Loss on Ignition (LOI) at 1000° C
Infrared combustion furnace/CS analyser to determine C and S
Co and Cu by 5% sulphuric acid leach with ICP-OES or AAS finish
Full ICP-OES and ICP-MS elemental suites by sodium peroxide fusion
Full ICP-OES and ICP-MS elemental suites by 4-acid (HCl-HNO3-HF-HClO4)
digestion
Full ICP-OES and ICP-MS elemental suites by aqua regia
digestion
