Freeport-McMoRan has announced plans to cut production at a number of its operations around the world as the Covid-19 pandemic interferes with mining operations and the global supply chain.

The miner said that it would cut molybdenum production in half at its Climax mine in the US state of Colorado, down from a peak last year of 17 million pounds of molybdenum, and that it would make a series of layoffs at its Chino mine in New Mexico, which was closed down last month after three workers tested positive for Covid-19.
