Green copper and clean smelting and refining are envisaged at Orion Minerals’ quickly advancing base metals mines in South Africa’s well-endowed Northern Cape province, which has historically produced 2.5-millon tons of copper until base metal mining ceased there several decades ago. The fully permitted and already reviving Prieska mine will begin producing its first saleable copper and zinc 12 to 18 months after finalising its total funding requirement, which is estimated at from R3-billion to R4-billion.
