SANTIAGO - The mine supervisor union for Chile's Centinela mine, operated by mining company Antofagasta, decided to extend negotiations to avoid a strike, the union said on Monday.
The union said in a statement that the company had made a new, much better offer, causing union leaders to hold off on threats of a strike to discuss the offer with union members.
The union said talks would be extended through Tuesday and Wednesday.
Union members had rejected a previous proposal from the mining company in mid-May, and began a mediation period with the government last week.
In 2022, Centinela produced 247,600 tonnes of copper, according to data from the state agency Cochilco.
