The miner Freeport-McMoRan has reportedly reached a tentative agreement with union workers at its Papua site in Indonesia over their wages and pensions.
Reuters quotes a union spokesman, Juli Parorrongan, as saying this may avert a strike, but warns a final agreement would have to be reached this week.
The negotiations were suspended in May when a tunnel collapse killed 28 people, but resumed in June.
Freeport Indonesia employs about 24,000 workers, including contractors and staff.
Relations between Freeport and unions have been strained in recent years following a three-month strike in 2011, May's deadly tunnel collapse and a series of minor spats.
