ANTOFAGASTA, Chile, March 20 (Reuters) - The striking union at BHP Billiton's Escondida, the world's largest copper mine, is open to further conversations with the company that could lead to reopening negotiations, a union spokesman told reporters on Monday.
"We're going to see if that could put in place a dialogue going forward," union spokesman Carlos Allendes said after exiting a meeting with BHP in the city of Antofagasta.
"We're hopeful. We have the willingness, and we're going to wait." (Reporting by Felipe Iturrieta; Writing by Gram Slattery; Editing by Sandra Maler)
