Barrick Mining’ board of directors 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.

“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,” said John Thornton, chairman of the board.

“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 Thornton.

Barrick Mining engages in the exploration, mine development, production, and sale of gold and copper properties. It has ownership interests in producing gold mines that are located in Argentina, Canada, Côte d’Ivoire, the Democratic Republic of Congo, the Dominican Republic, Mali, Tanzania, and the United States. The company also has ownership interests in producing copper mines located in Chile, Saudi Arabia, Zambia, and various other projects located throughout the Americas, Asia, and Africa. Barrick Gold Corporation was founded in 1983 and is headquartered in Toronto, Canada.
