Did some prospecting around for something other than Cassiterite, and found a "vein" of Chalcopyrite, however after tunneling in, this is my discovery.
Should I keep digging deeper, or did I just get fucked by the ore gods?
as long as you understand how to play minesweeper, just mine away and see what you find. i usually find viens around other viens of the same type, so maybe youll be lucky like me in that regard.
ive found a lot of veins that are literally like 5 tiles and once you dig those 5 you dont get another prospecting hit on that same area when you try again so... YMMV.
