SANTIAGO, Sept 9 (Reuters) - Chile's state-owned copper miner Codelco said late on Friday that unionized workers at its small Salvador copper mine have accepted a wage offer and ended a strike, which had been ongoing since Monday.
Salvador is in the process of restarting its smelter, refining, mining and plant operations, while workers are returning to their posts, Codelco said in a statement.
Salvador produced 49,000 tonnes of copper in 2015. It is the world No. 1 copper exporter Codelco's smallest and highest cost mine, and the company is battling to keep a lid on costs to ensure production is viable at a time when copper prices are low. (Reporting by Anthony Esposito)
