According to the NDRRMC, search operations were increased on Saturday to include five sniffer dogs and seven personnel from the Department of Defense but were suspended on Sunday morning due to heavy rains and further landslides. They are yet to resume.

Regional police director Chief Superintendent Agrimero Cruz Jr said the missing miners had a slim chance of survival, though he was hoping an air pocket might allow them to breathe, according to the Manila Standard.

The newspaper and other local sources reported that Cruz told the media that a human arm, believed to be from one of the miners, had been recovered floating in waters at the mine pit on Monday morning.

The NDRRMC reported that the Pani-an mine was temporarily closed while a Department of Energy geologist investigates the cause of the landslide.

The Semirara Mining Corp said in a disclosure to the Philippine Stock Exchange that it had commissioned a third-party consultant to review the company's operations.

“To aid in these [recovery] efforts, sniffing canines have been called in through the Office of Civil Defense. Further, the company has guaranteed financial, employment, scholarship and livelihood assistance to the families of those involved,” the company said.
