I just did the iron ore levels of mining in Badlands, took me about 2 hours to get through that and the mithril that spawned about there. Mining is queick there, stay around the rom and make a big figure 8 crossing between the 2 giant mesa's.
Btw this was at lvl 70, but I can't see you having any real problem there at 59.
