TORONTO, Sept. 29, 2025 (GLOBE NEWSWIRE) -- Barrick Mining Corporation (NYSE:B)(TSX:ABX) ("Barrick" or the "Company") today announced that the Company's Board of Directors (the "Board") has appointed Mark Hill as Group COO and Interim President and Chief Executive Officer, effective immediately, following the departure of Mark Bristow.

Mark 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. 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.

Mark Bristow is stepping down as President and CEO after nearly seven years having joined Barrick following Barrick's merger with Randgold in 2019. Mark Bristow led the successful integration of the two companies, and during his tenure made significant investments in Barrick's world-class assets to better position Barrick to maintain profitable gold and copper growth. Since the merger with Randgold in 2019, Barrick has returned $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.

John Thornton, Chairman of the Board, said: "On behalf of the Board, I want to thank Mark for his leadership of Barrick. During his tenure, Mark strengthened our portfolio and helped position Barrick as a leading global producer of gold and copper. As a result, the Company is well-positioned for the next phase of our growth and value creation for all shareholders. We wish Mark the very best for his future."

"We are delighted to welcome Mark Hill as Group COO and Interim President and CEO. His caliber, experience and deep knowledge of the Company will ensure we maintain momentum. The Board is committed to both finding the right leader to fully capitalize on Barrick's world-class assets and capabilities, and to driving improved performance, growth and shareholder value," added Mr. Thornton.

The Company continues to perform in line with our Full Year expectations as set out at Q2 results on August 11, 2025.
