|Exiting Ul'dah from the Gate of Nald, head directly East until you reach the mineral deposits on the cliffside near the Ul'dah Dispatch Yard. If you just stand on the steps and search with a spell, you will be led in the wrong direction. Go to Central Thanalan 23-27 and look at the outcrop of rock, with the trees to your left. Start to the left of the tree, and run behind the tree and onto the top of the rock. Hug the cliff face until the rock ends. Jump down. Follow the lower path back to the tree. Of course, you should mine any deposits you see. I got 3-4 deposits per circuit, and it was a short circuit. The only things available in this circuit are shards and bone chips (and experience, of course).
