SINGAPORE, June 25 (Reuters) - Copper prices rose on Tuesday, amid worries over supply, after thousands of workers of Chile's Codelco rejected the company's offer during the weekend and extended the strike at a major mine.
Workers at Chuquicamata, one of the world's biggest copper mines, have been on strike since mid-June to demand better healthcare and retirement benefits, hurting output of state-run Codelco, the world's top copper producer.
"Supply side issues overweighed concerns about the economic backdrop. Copper prices remained supported by the ongoing strike at Codelco's Chuquicamata copper mine," said ANZ in a note.
