Graham Kerr

Graham Kerr was CEO of South32, the Sydney-, Johannesburg- and London-listed diversified mining group spun off from BHP in 2015, until stepping down on July 1, 2026, when he handed over to successor Matt Daley while remaining as a strategic advisor on the Alcoa aluminium transaction. During his tenure he oversaw a portfolio spanning aluminium, manganese, zinc, lead, silver and copper assets across Australia, Southern Africa and the Americas, including South Africa's Hillside Aluminium smelter, Mozambique's Mozal smelter, the Hermosa (Taylor) zinc-lead-silver project in Arizona, and manganese mines in South Africa's Northern Cape. Kerr led South32 through the closure of Mozal in March 2026 after the company failed to secure affordable long-term power from Mozambique's Hidroeléctrica de Cahora Bassa and South Africa's Eskom amid drought-hit hydropower supply, a decision affecting thousands of direct and indirect jobs in Mozambique. He also championed Hillside Aluminium's thirtieth anniversary in 2026, highlighting its contribution of more than R35-billion to South Africa's GDP between 2015 and 2024 and its role in supporting roughly 3 650 direct and indirect jobs, while driving negotiations with Eskom on a long-term, lower-carbon electricity solution for the smelter beyond 2031. Under his leadership South32 also advanced the Taylor zinc-lead-silver project despite rising capital costs, pursued copper growth through Sierra Gorda in Chile, and pursued the sale of its aluminium value chain to Alcoa. Kerr frequently represented South32 in engagements with the South African government, including appearances alongside President Cyril Ramaphosa, and in media briefings on the group's operational and strategic direction.
