The copper operations in Zambia of South Africa’s Jubilee Metals showed strong growth in the six months to December 31, with further sharp increases expected going forward. The Johannesburg- and London-listed Jubilee, led by CEO Leon Coetzer and chaired by former Mpumalanga Premier Mathews Phosa, recovers copper in Zambia and chrome and platinum group metals (PGMs) in South Africa, from historical waste rock, run-of-mine materials and tailings.
