The collapse occurred before noon yesterday in west Borneo, in a hilly area where illegal gold mining is rampant, the official said.
"We conducted a search operation last night, but we have stopped the operation now as we have found all of the bodies reported to be missing," local rescue official Leonardus Sabar Umbara told AFP.
The victims included a 17-year-old male, Umbara added.
Illegal gold mining has boomed in Indonesia in recent years as the price of the precious metal has surged, and deaths are common.
