i can't find the bedrock ore and i not have any idea to extract

Bedrock ore generates under square patches of depth rock, unlike depth nodes which are spherical.

what about bedrock oil deposits?

also i think it might be possible to destroy bedrock oil deposit cos i was doing explosive mining and found an empty area in bedrock, the explosives i used werent strong enough to destroy depth rock though

Bedrock oil can be seen from the surface from the patches of oily dirt/sand it generates.
