I can tell you that nobody in my group macro'd, we just rushed carrots, plaice and exploration, got one guy up to seeing rustroot and went from there. There are probably some mines still out there so hang in there.
I would like to add that some kind of centralized trading location would really be nice - on the old map before I found a mine, it was a trivial matter to get together some chantrelles or silk and meet someone at the RoB to pick up a few metal bars. Something like this would go a long way to alleviate the metal blueballs that a lot of people seem to be experiencing.
