Let me translate the Tagalog text in the photo to English:

Q12: What are the layers of soil or gravel which can be found while digging for TH?

IMHO: Different designs have been observed from various kinds of digging or tunnel. Some are shallow, about 20 meters only; others are more or less 50 meters deep. Some of the treasures were buried so deep. This means one may encounter many and different kinds of mud or soil throughout the digging. There were areas recorded to have 10 to 12 types of soil cover. Expect to find a mixture of mud and ordinary soil, of black or coffee brown, sometimes wood chips are mixed with them. The most common soil cover used is a mixture of gravel and corals, and at times,powdered shell. It was suspected that these kinds of soil cover give protection to the buried treasure from metal detector.

Thanks!
