Apo Land and Quarry Corp. said Thursday, that while it held mining rights to the area, it had no quarry operations there.

"Operating in that area is not part of our pipeline this year or next year," company representative Chito Maniago said in an interview with ANC's Market Edge.

Before the landslide struck, the company warned local authorities and the Mines and Geosciences Bureau about "cracks" in the area, he said.
