What I meant was mining Ifrit's Cauldron(a zone, you have to go through Yhoator Jungle to get there). It drops very good ores including iron, darksteel, adaman, and orichalcum. The problem is, even a LV75 player will still get agro there, so you MUST bring some way to stealth yourself. A good way to go is either at least 20WHM/10NIN(sneak at LV20, tonko at LV10) or 40NIN/20WHM. The reason you want NIN sub is that many of the mining points are right next to bombs, which agro magic. Tonko(nin's inivisible spell) does not agro them, but the Invisible spell from WHM will. Other than that you will also need sneak to get past various bats/raptors and other aggresive mobs. It can be a frustrating area to mine in, but after you get used to it very profitable as there is very little competition(no gil sellers there on my server, period).
BTW here's a good website for mining maps:
