Lang brings more than 40 years experience in the mining industry to the table, replacing Alan Hibben as agreed under a settlement with a major shareholder over a bitter battle for a board overhaul.
Lang has deep experience in relevant fields of engineering, development and production at gold, copper, coal and platinum group metals operations.
He was CEO of Centerra Gold from 2008 to 2012 and served as Centerra's board chair from 2012 to 2019. Lang has also held senior operating positions at Stillwater Mining Company, Barrick Gold, Rio Algom and Kinross Mining.
Lang holds a Bachelor of Science degree and a Master's degree in mining engineering from the University of Missouri-Rolla.
Hibben has stepped down as chair but will remain on the board as an independent director.
Former Nevsun Resources president and CEO Peter Kukielski continues to serve as interim CEO while the search committee looks for a suitable permanent appointee.
Kukielski was one of the nominees put forward by Waterton Global Resource Management, Hudbay's second-largest shareholder, and was an agreed nominee as part of the settlement struck between Waterton and Hudbay days ahead of the miner's May AGM.
At C$4.45, Hudbay shares (TSXHBM) continue to trade near the bottom-end of its 12-month range of $3.98-$10.42, which gives it a market capitalisation of $1.16 billion.
