Markets & logistics

Built for the Copperbelt, via Lobito

Output serves copper and cobalt producers in all major producing regions. The Copperbelt (DRC/Zambia), reached via the Port of Lobito, is a major market — with a shorter supply route than long-haul supply from Asia.

Sines → Lobito → Kolwezi
