The world’s largest gold, and second most important copper, mine, came to a standstill last week, not long after it had resumed operations following a three-month strike. The Grasberg mine in Papua is operated by US company, Freeport McMoran – which also has a 60-40 joint venture agreement with Rio Tinto in the lease area. According to the company, some unionised workers, who recently returned to the mine, have attacked others who refused to support the recent strike. But the union has accused the management of trying to discredit it, and failing to honour a pay agreement reached in January.
