Ok, so I am finally at the level to find rustroot. Problem is that it's still fairly rare, so I need manage what I have wisely. Say I have a Q 25 rustroot extract and I take it into a cave. Calculating the formula I supposedly get a 5625 tile length for this Q? I GOTTA be doing that wrong because that sounds enormous. Basically with a size like that.. if I come up with no minerals found then that means the caves pretty effing dry. So I end up with that error. I went in deeper (no where near 5625 tiles) and BAM it tells me there's copper under me.
Basically I am asking just how far should I move from spot to spot with prospecting with a 25 Q rustroot extract so I don't waste any.
Thanks in advanced to anyone who can help me.
