Jubilee Metals' CEO Leon Coetzer told Proactive it is now reaping the benefit of a huge investment programme in its chrome and platinum group metals operation in South Africa.
All of these operations came onstream in March and April, while in Zambia it has now commissioned a new integrated copper cathode facility.
This increased scale in both countries is seeing costs tumble in South Africa, said Coetzer, while Zambia is set to increase copper production by four-fold alongside a new cobalt circuit also coming online.
