Workers at Chile’s Codelco-owned Radomiro Tomic mine have rejected an early wage proposal.

Union leader Erwin Mascayano said the proposal, which included bonuses and loans totalling $31,000 for each of the 760 workers, has been rejected by the workers, reports Reuters.

Mascayano added the workers’ contract expires in November and wage talks are expected to begin in mid-October.

Radomiro Tomic, located 1,040 miles north of capital Santiago, produced 440,000t of refined copper in the first half of 2010.
