A while back I bought a couple pickaxes and went to the Palborough Mines to try my luck at mining. I had no idea what I was doing, didn't have any mining equipment or any idea of what I would find. Anyway I went and I found a few mining spots and dug up a few chunks of mythril gravel (i think that's what it was called). I took the chunks and saw a refinery machine located in the mines. Curiosity got the better of me and I put all the chunks in and turned the machine on. I then went and picked them up at the bottom of the machine. They had turned into Mythril Sand (or Mythril Dust, not sure). I was just wondering what the point of these are since I've had them for a while and they are taking up space in my mog house.
