Philippine officials say they have resumed the search for victims of a landslide that killed more than 20 people at a remote gold mining area, but that they are uncertain how many more remained buried in the rubble.

The landslide took place early Thursday in Pantukan township of Compostela Valley province. Civil Defense chief Benito Ramos says early reports of about 100 people still buried were inaccurate.

Ramos says those estimates were far too high, but that the exact number is uncertain. He says local authorities do not record the number of mostly migrant miners who work there.

Rescue work was suspended Thursday because heavy rains threatened to unleash fresh slides in the area. Geologists warned months earlier that the area is highly susceptible to sudden landslides.
