De Beers parent company Anglo American once held a stake in AngloGold Ashanti but sold off its remaining shares in 2009.
De Beers said Madondo has leadership experience and a proven track record of delivery, particularly when it comes to leading underground mining operations, and overseeing safe operations.
“He is the ideal candidate to lead our managed operations business as we continue the successful delivery of the $2 billion Venetia underground project in South Africa and maintain strong operational performance at Gahcho Kué mine in Canada,” De Beers CEO Bruce Cleaver said in a press release.
“His expertise will be essential as we continue to deliver the benefits of our FutureSmart Mining program, while ensuring we remain steadfast on our ambitious Building Forever sustainability commitments.”
Madondo holds a bachelor’s degree in mechanical engineering and an Executive Master of Business Administration from the University of Cape Town and has completed an Advanced Management Program through Harvard Business School.
He recently served on the Board of the Minerals Council South Africa and Rand Refinery Limited.
Madondo is slated to start at De Beers on Jan. 1, succeeding Nompumelelo “Mpumi” Zikalala, who, as previously announced, is leaving De Beers to become CEO of Anglo American’s Kumba Iron Ore business.
