Grasberg mine: production restart delayed

Workers of the Freeport McMoRan's Grasberg copper mine have postponed the restart of production citing technical problems. The management and workers have had a three-month dispute over the wages that resulted in growing concerns over the copper supply. The production standoff supported metal's prices amid weak investor's confidence.  However, the mine is likely to restart operations by the end of this week thus weighting down on the metal's price.
