De Beers man to head Firestone

Diamond producer De Beers’ chief financial officer Stuart Brown is leaving after 20 years to join Aim-listed miner Firestone Diamonds as chief executive. Firestone’s incumbent boss Tim Wilkes will remain at the company as an executive director. Brown’s appointment comes as Firestone tries to strengthen its executive management team ahead of developing a plant at its flagship mine in the Lesotho highlands in Africa.
