Fastest Way to Mine Iron / Coal? Help and Advice Forum Mar 26, 20060183;32;I once did a similar thing. I was going to mine 700 iron and 1400 coal to get my mining to 60 and my smithing to 50. The 700 iron wasnt that hard, I mined it at the Al Karid spot with 3 rocks all next to each other (thats what it takes if you have a rune pick) This took me several hours. The coal took me several weeks.
