Toronto: Barrick Mining appointed veteran executive Mark Hill as interim president and CEO on Monday following the sudden resignation of Mark Bristow, who led the Canadian miner for nearly seven years after its merger with Randgold Resources.

Bristow, who became CEO in 2019 when Barrick acquired Randgold, oversaw the integration of the two companies and steered the miner through a period of significant portfolio reshaping and debt reduction.

“Disappointed to see him leave, he has been a fine leader,” said Peter Letko, of the Letko Brosseau investment fund, one of Barrick’s shareholders. Bristow indicated in May he would stay in his current role until 2028, a timeline that would have allowed him to oversee the development of the company’s Reko Diq copper and gold project in Pakistan.

The announcement was therefore “surprising”, analysts at Citi said in a note. “One question is whether this will lead to bigger changes at Barrick,” they said. “A new CEO could bring a new strategy in Mali, at Reko Diq or for the portfolio.” Hill, who will also continue to serve as group chief operating officer, takes charge immediately as the board begins a global search for a permanent chief executive with the help of an external firm, named by one source as Egon Zehnder.

The board has been looking at succession planning for some time, driven, according to one source with knowledge of the matter, by the business’s relative underperformance compared to competitors over the past five years.

Shares in Barrick, which owns 13 mining assets across Africa, Asia, Latin America, and North America, have lagged some rivals, rising by 37pc since 2020 compared to a 110pc climb in shares of fellow Canadian miner Agnico Eagle, with gold prices hitting record highs. US-listed shares of Barrick were marginally higher in premarket trading on Monday.
