SANTIAGO, June 11 (Reuters) – Unionized workers at BHP Billiton’s Spence copper mine in northern Chile have approved a new labor contract, union president Ronald Salcedo said on Monday.
Spence is one of the Anglo-Australian miner two mines in Chile. The other, Escondida, the world’ largest copper mine, earlier this month entered into labor negotiations following a historic strike that shut down the mine for 44 days last year, depriving BHP of $1 billion in production.
