LONDON: Copper pulled back from the previous session’s three-week high on Friday as momentum sparked by a strike at one of the world’s biggest copper mines, Indonesia’s Grasberg, eased ahead of the long weekend break in China, the US and Britain.
Freeport McMoRan Inc said on Thursday that mining and milling rates at Grasberg had been affected by an extended strike and that a “large number” of about 4,000 absentee workers were deemed to have resigned.
“The Grasberg news yesterday ... has now been factored in, so there’s a bit of profit-taking, but copper should find good dip-buying support for the rest of today, given that it’s a long holiday weekend,” said Societe Generale analyst Robin Bhar.
Dutch bank ING said in a note that Freeport has about 100,000 tonnes of copper stocks that could be used to meet demand in the near term.
The metal remains rangebound, Bhar said. “Although people are prepared to buy the dips, they’re also prepared to sell the rallies,” he said. “We need to get through overhead resistance and move above some of the longer term moving averages.”
