The form and size of the galleries is not fixed, but flexible depending on the composition of the ore layers and the different characteristics of the deposit. These criteria are assessed by the miners during underground and surface gophering for copper minerals. This variability explains the changes in form and size of galleries, which often have no regular geometric profile and no strict direction.
The galleries' dimensions and structure are not fixed but can change based on ore layer composition and deposit characteristics. Miners evaluate these factors during exploration for copper minerals. The resulting variations cause alterations in gallery shape and size, which typically do not follow a consistent geometric pattern or have a clear orientation.
