Another union joined the strike later in the same month, forcing the closure of the copper mine.

Located in Chile’s Atacama Region, the Candelaria copper mining complex comprises two adjacent copper mining operations, Candelaria and Ojos del Salado.

In November 2014, Lundin Mining acquired an 80% ownership stake in the Candelaria and Ojos del Salado copper mining operations for $1.8bn from Freeport-McMoRan.

In a statement sent to Reuters on 3 November, the company stated: “During the negotiation process, Minera Candelaria has submitted four improved offers.

“Once again we call on the leaders and members of the Mina Union to resume the dialogue to reach a mutually beneficial agreement.”

The union confirmed the news agency about its ‘decision to reject the proposal’ and said it will continue with the ongoing strike.

Due to the current labour action, Lundin withdrew this year’s production guidance of 145,000t-155,000t of copper (Cu) and 80,000oz-90,000oz of gold (Au).

Last year, Candelaria produced 111,400t of copper.

In July 2015, Lundin Mining received the EIA approval for Candelaria copper mine.
