UPDATE 1-Chile's Collahuasi copper mine running normally as strike ends
(Adds company's comments)
SANTIAGO, June 16 (Reuters) - Operations at Chile's Collahuasi copper mine were running normally on Tuesday after workers returned to work following a one-day strike, and any possible impact on production is being evaluated, the company told Reuters.
"As of 7 a.m. local time (1000 GMT) today, Collahuasi is operating normally," the company said.
Collahuasi, one of the world's largest copper mines, is a partnership between Glencore Plc and Anglo American Plc . In 2014, the mine produced around 470,400 tonnes of copper, or nearly 8 percent of Chile's total output.
Collahuasi said it "is evaluating the possible impact on its production."
Workers at the mine downed tools Monday morning over working conditions and benefits.
"Collahuasi, as is policy, has always held meetings with union leaders to address labor issues, but it will not accept meetings initiated by illegal and illegitimate pressure," the company said.
Union officials were not immediately available for comment.
Chile, which produces a third of the world's copper, is struggling with dwindling ore grades in many of its aging deposits, although new mines and recoveries in troubled ones are pushing up overall output. (Reporting by Fabian Cambero and Anthony Esposito; Editing by Paul Simao and Diane Craft)
