Barrick Appoints Sebastiaan Bock CEO, Rest of World

Bock Will Lead Portfolio Outside North America, Report to Barrick CEO Mark Hill

TORONTO, Aug. 11, 2026 (GLOBE NEWSWIRE) -- Barrick Mining Corporation (NYSE:B)(TSX:ABX) today announced the appointment of Sebastiaan Bock as Chief Executive Officer, Rest of World, effective immediately. Mr. Bock will lead Barrick’s gold and copper operations and projects outside North America and will report to Mark Hill, President and Chief Executive Officer of Barrick.

Barrick’s rest of world portfolio includes gold and copper assets across Africa, the Middle East, Latin America, and Asia Pacific. It produces more than two million gold equivalent ounces a year and is expected to grow by more than 20% over the next three years.

John Thornton, Barrick’s Chairman, said, “Outside North America, our Rest of World portfolio has a distinct advantage: our ability to work with Chinese partners, including joint mine ownership and co-investment. This can enable higher efficiency; broader access to advanced technologies, including those revolutionizing exploration, operations, processing, and information management; access to leading equipment suppliers and comprehensive and agile supply chain solutions; and partnership opportunities including shared infrastructure, resources, and solutions, to derisk and improve outcomes.”

“Seb’s experiences and accomplishments are tailor-made for Barrick to build on this unique advantage,” said Mark Hill, Barrick’s President and CEO. “He has experience across operations, finance, strategic planning, geopolitical issues, human resources, and risk management. Seb is the ideal person to grow our Rest of World business. He is a perfect example of Barrick’s deep and global bench, and the integrity and character of its leaders.”

“I am excited to accept this new role quite simply because what Barrick does, matters,” said Bock. “It matters to the thousands of employees and stakeholders I’ve been honored to work with over the years. It matters to the communities where we work to create lasting and shared benefits. It matters to our investors whose wellbeing is affected by how well our work is done. These partnerships will allow us to realize the benefits of our unique rest-of-world strengths.”

Mr. Bock joined Barrick as Senior Vice President and Chief Financial Officer, Africa and Middle East, in January 2019, and was appointed Chief Operating Officer for the region in July 2022. Under his guidance, the region has met or exceeded guidance every year and achieved significant growth. He has led the Lumwana expansion, the resolution of the situation in Mali, the achievement of record throughput at Kibali, and the growth of gold reserves at Loulo-Gounkoto and Bulyanhulu.
