Dozens of student demonstrators pelted the office of gold miner Newmont Nusa Tenggara on Monday over a recent court ruling allowing it to continue dumping tailings in Senunu Bay in West Sumbawa district.

The protesters from the West Nusa Tenggara chapter of the National Student League for Democracy (LMND-NTB) threw rotten tomatoes and bottled water at NNT's representative office in Mataram, the provincial capital. Police and NNT security guards did not respond to the pelting.

Andra Ashad, the LMND-NTB chairman, said NNT should be forced to cease operating its Batu Hijau mine and leave the province. "There is no alternative but for us to kick Newmont out of West Nusa Tenggara," Andra said.
