SANTIAGO, Oct 19 (Reuters) - Chile´s Candelaria copper mine, owned by Canada's Lundin Mining, announced it would suspend operations beginning Tuesday after two of its workers' unions walk off the job.

In a statement late Sunday, the company said it made the decision to ensure the safety of its workers.

"Given the constant blockades, the attacks on our staff and facilities that put the safety of our workers at risk... Candelaria has decided to suspend its operations as of October 20," the mine said in the statement.

Candelaria´s "Mine Union" began a strike on Oct. 8, while the "Candelaria Union" said it would walk off beginning Oct. 20. Both unions failed to reach agreement with management on new collective labor contracts.

The company reiterated in a statement its willingness to continue talks. The unions, however, have said the company has tried to impose its own conditions during the talks.

Candelaria produced 111,400 tonnes of copper in 2019 and had reached 74,200 tonnes as of August this year. (Reporting by Fabian Cambero; Writing by Dave Sherwood; Editing by Louise Heavens)
