Copper rises after Chilean mine strike

Copper prices rose on Friday, after Capstone Copper announced that a workers’ strike forced a production?halt at the Mantoverde Mine in Chile.

The most traded copper contract on the Shanghai Futures Exchange closed daytime trade up 0.64% at 101,340 yuan ($14.553.65) per metric ton but ended the week lower by 0.52%.

As of 0700 GMT, the benchmark three-month Copper on the London Metal Exchange had gained 1.30% and was expected to finish the week with a gain of 0.93%. The strike was triggered after Capstone and the largest union of mine workers failed to reach an agreement on collective bargaining. The company said on Thursday that a takeover began at the mine's desalination facility last Sunday. This led to disruptions.

It was predicted that the mine would produce between?29,000 to 32,000 metric tonnes of copper cathodes by 2025. Freeport-McMoRan, a copper miner, said Thursday it expects about 85% - of production to be back online at its flagship Grasberg Mine, the second-largest copper mine in the world, by the'second half of the year. In October, a deadly mudflow shut down the mine and killed several workers. This sparked supply concerns and triggered a copper rally.

The dollar index registered its biggest one-day fall in six weeks on Thursday, making greenback-denominated commodities cheaper for investors using other currencies. Greenland fears also diminished after U.S. president Donald Trump reversed his tariff threats and said that he would not take over the island with force.
