Origin of Material
The material for this CRM was sourced from the Mufulira mine, which is a sediment-hosted stratabound copper deposit in the Zambian Copperbelt. The mine site is located 10km south of the border of Democratic Republic of Congo.
Approximate Mineral and Chemical Composition
The Mufulira Mine is characterized by chalcopyrite mineralisation in Contact Shale and copper rich sections. Pyrite mineralisation increases at the expense of chalcopyrite in the upper part of the South Orebody Shale, and a zone of exclusively pyrite mineralisation occurs at the top. Bornite is typically absent from the ore formation, but minor occurrence appears on the fringes of the barren gaps, particularly in the contact shale. In order of importance, chalcopyrite, chalcocite and bornite are present in the mineralized footwall. Higher cobalt values are concentrated on either side of the geological footwall.
