Day 279:
I chased a vein of ore out of the chamber I was in down a good 4 meters, and found myself in another cave I’ve previously mined out. (Although apparently I didn’t do a thorough job if I just chased a vein of ore in there… on the other hand, I’m missing my laser-guided mineral scanner, so I’m not beating myself up over it much.)
So now instead of straightening up the one I was in (which was pretty clean to begin with) I’ve started reshaping this one. Because I’m already digging the wrong direction, why not keep going?
