The labour union of Antamina Antamina copper-zinc mine in Peru SUTRACOMASA has ended a strike that has been ongoing since 10 December and is set to resume to work.
The first union strike, which ran from 10 November to 30 November was declared both unlawful and illegal by the government labour authorities at each stage of legal proceedings.
Minera Antamina said in a statement: "In both strike proceedings, SUTRACOMASA was claiming the alleged existence of failure to comply with provisions of the collective bargaining agreement, and demanded a bonus to compensate the lower amount of profit sharing.
"As it is well known, profits are variable income and our company faces a business scenario in which a lower level of production coincides with an international market in which there are lower prevailing prices for the mineral products that the company produces."
During the strike, the mining company called for the establishment of a process of transparent dialogue and understanding without any form of pressure.
According to Antamina, the strike had not affected production, although the union has said that around 60% of operations were impacted.
BHP Billiton and Glencore Xstrata own a 33.75% stake in the mine, which produced 273,411t of copper between January and September.
Teck owns 22.5% and Mitsubishi holds 10% in the mine.
