Ok, so i 've ask about prospectiong. i 've learn how to use it and i start doing it.
the pick says i have very good chanse to find X ore, moderate chanse to find Y and so on, so i though i've found a good spot. i start digging. 6x6 wide 55 block deep until i reach quarz bottom(lol did you get it? quarz bottom?...nevermind)...7 copper pickaxe broken...not a single block of ANYTHING, just granite and chalk..
so i just cry, rinse and repeat the process. prospectingPick says "yeah boy. thats the spot, trust me! " and i was all like "yeay boiiii".... again not a single block of ANYTHING.. and now i'm running out of copper! i just have enough for 2/3 more pickaxe(maybe)
what i'm doing it wrong?
