i got a cave, and at first i was doing a snake, but since i do not know where/if there is a metal node close by, should i hit the wall like i do when i search for river clay, bout every 20+ paces hit the wall?
also will the first wall give me metal, or do i have to go through the "cave wall" and then mine the second tile before i get to any ore?
thankyou for the replies folks
