LONDON (Reuters) - Copper prices on the London Metal Exchange jumped on Friday to their highest level since June 2015, on talk of BHP Billiton (BLT.L) (BHP.AX) declaring force majeure on shipments from its Escondida mine in Chile, traders said.
Benchmark copper CMCU3 rose 4 percent to a session high of $6,056 a tonne. It was trading at $6,042 a tonne at 1451 GMT.
A BHP spokesman said he was unable to immediately confirm that force majeure had been declared.
