SANTIAGO, Oct 9 (Reuters) - The president of the union of workers at Chile´s Collahuasi copper mine confirmed on Friday it had reached a labor deal with the mine operator, averting the risk of a strike at the sprawling deposit.

The talks at Collahuasi - a partnership between Glencore and Anglo American with Japanese firms - were widely seen as the most sensitive of 2020 in top copper producer Chile, both because of the size of the union involved and the mine´s importance to the country´s total output.
