The quarry source for sand and gravel is from the Chico River notably within the barangays that are close in this river but the major source is found in central Bontoc. Other barangays, sand and gravel is found in the tributaries of this river but it is very minimal. The Bayyo side of Mount Polis bordering the municipality of Banaue is also a potential source of mountain sand and gravel but it is not as good with the Chico quarry source.
