Origin of Material
This standard was made using oxide ore sourced from the Kansanshi Mine, located in the North Western Province of Zambia, The mine is located approximately 10 kilometers north of the town of Solwezi, 180 kilometers to the northwest of the Copperbelt town of Chingola and 16 kilometers south of the Democratic Republic of Congo border. Kansanshi, Africa’s largest copper mine, is 80% owned by Kansanshi Mining PLC, a First Quantum subsidiary. The remaining 20% is owned by a subsidiary of ZCCM. The Kansanshi deposit occurs within the Lufilian arc, a major tectonic province characterized by broadly north directed fold and thrust structures, which hosts the world class Central African Copperbelt. The deposit at Kansanshi occurs within a broad, northwest trending, north-west closing antiform, which can be traced for approximately 12 kilometers. Kansanshi is a vein deposit developed 3 within a tectonised rock sequence and, as such, constitutes a major mineralization control. The main veins and vein swarms dip sub vertically, perpendicular to the fold axes, in the plane of maximum extension.
Approximate Mineral and Chemical Composition
Deep tropical weathering has resulted in supergene enrichment and subsequent partial oxidation of the deposit. Primary copper sulphide mineralization is dominated by chalcopyrite, with very minor bornite, accompanied by relatively minor pyrite and pyrrhotite. Oxide mineralization is dominated by chrysocolla with malachite, limonite and cupriferous goethite. The mixed zone includes both oxide and primary mineralization but also carries significant chalcocite, minor native copper and tenorite. Some copper appears to be carried in clay and mica minerals, where it is essentially refractory.
