Rescue workers have saved a child more than two days after a landslide struck a southern Philippine province killing at least 15 people.

The landslide happened on Tuesday night outside a gold mining site in the town of Maco in the province of Davao de Oro, burying homes, including three buses and a jeep that were supposed to ferry employees of the mining company.

Provincial authorities said the child who survived was in stable condition, raising hopes that more survivors would be found.

The number of missing remained at 110.

Disaster officials previously reported that two buses, carrying 27 passengers were buried, but mining operator Apex Mining said in a statement on Friday that four vehicles were found buried in the landslide.

A communications officer at Apex said the company had no information yet on how many passengers the vehicles were carrying when the landslide occurred.

Apex earlier said the buses have a 60-seating capacity, while the jeep can sit 36 passengers.

Torrential rains have battered Davao de Oro in recent weeks, triggering floods and landslides.
