Avocet names new chief executive

West Africa-focused Avocet Mining has named engineering veteran David Cather as its new chief executive, as it seeks to reassure the market on its operations and boost shares battered by reduced output outlook and worries over expansion plans. The miner said yesterday it had accepted Brett Richards’ resignation, appointing mining engineer Cather, who joined the company in May 2012 as chief operating officer, in his place. Last month, Avocet cut its production outlook for the full year citing equipment availability issues.
