Bock was appointed on 11 August 2026 to run all Barrick's gold and copper operations outside North America, including its African mines, reporting to Mark Hill ahead of the North American IPO. He joined the Africa and Middle East region as chief financial officer in January 2019 and became its chief operating officer in July 2022, a period that included the Lumwana expansion in Zambia, record throughput at Kibali and the resolution of the Loulo-Gounkoto dispute in Mali.
Career moves on record
- Appointed
Chief Executive Officer, Rest of World, Barrick Mining Corporation
Barrick created a new 'rest of world' chief executive post and gave it to former Randgold finance executive Sebastiaan Bock, putting him in charge of the group's mines in Africa, the Middle East, Latin America and Asia-Pacific. Bock had been Barrick's COO for Africa and the Middle East since 2022 and was part of the team that settled the long-running Loulo-Gounkoto dispute with Mali, and his appointment comes as Barrick prepares a minority listing of its North American business.
