SINGAPORE, July 13 (Reuters) - Shanghai copper hit its highest in nearly 25 months on Monday, while London copper scaled a 24-month high, on supply worries from top producer Chile due to a potential strike at a mine.

The most-traded August copper contract on the Shanghai Futures Exchange jumped as much as 6% to 53,520 yuan ($7,642.66) a tonne, its highest since June 15, 2018.

Three-month copper on the London Metal Exchange climbed as much as 3.3% to $6,622.50 a tonne, a level unseen since July 3, 2018.

Workers at Antofagasta Minerals's Zaldivar copper mine in Chile voted in favour of strike action after rejecting a pay offer, the mine's union said on Friday, adding that a strike had been set for July 15, pending government mediation.
