07:15 AM EDT, 09/29/2025 (MT Newswires) -- Barrick Mining Corporation ( B ) was at last look up 1% in US premarket trade Monday as it appointed Mark Hill as group COO and Interim President and Chief Executive Officer, effective immediately, following the departure of Mark Bristow, while the company moved to try and ease any market concerns around this news by saying it continues to perform in line with its full year expectations as set out at Q2 results on August 11, 2025.

A statement noted that Hill, who is currently responsible for Barrick's Latam and Asia Pacific regions, is a seasoned mining executive with 30 years of experience. He joined Barrick in 2006 and has experience in strategy, corporate development and leading major projects across the world, and was also integral in the initial decision to undertake exploration at the Fourmile gold project in Nevada.

Meanwhile, the search committee of the board, chaired by Brett Harvey, has embarked on a process with the support of a leading executive search firm to identify a permanent President and CEO.

Monday's statement also noted Bristow is stepping down as President and CEO after nearly seven years having joined the company following its merger with Randgold in 2019. Since the merger, the statement said, Barrick has returned US$6.7 billion to shareholders and reduced net debt by $4 billion. Most recently, the company delivered "solid" Q2 operating performance, strong cash flows, an enhanced quarterly dividend and strong share price performance.
