Regional metal scarcity or bad rustroot?

well, I didn't really mean 1 tile node

have to say that sometimes prospecting does not look correct: i'ìve started prospecting from the entrance of a cave (outside) and found ore only 50-60 tiles away from it, only to find that the vein extended toward the cave entrance enough to get to it, while mining the vein itself.

At this point, with improved quality rustroot, I've prospected the entire cave system across a pretty significant region of a continent with zero hits, lol.

Can confirm oreless deadzones exist and can go for 10+ minimaps.

Any inkling as to whether it's dead on one level or dead all the way down?
