OREAS 553b
OREAS 553b 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. Twenty-six 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
