I mean, if I mine a tile in cave and nearby tiles turn into brown color, and I mine one and get a feldspar - does it mean there is only feldspar, or is there a chance that any of the uncovered tiles is ore, even though it looks the same?
All cave walls initially look the same.
After mining the cave wall until it collapses all walls near it will be revealed, making them change colour.
This colour represents what stone or ore the wall has.
You'll have to figure out which ones give stone and which give ore.
