I spent a lot of time among the ogres in the snowy area above Southshore with my paladin. If you don’t mind grinding, this is a great spot. The ogres are easy to single pull. They are about your level. And they drop lots of silk that can be used for trade skills or sold in the auction house. Best of all iron, mithril and truesilver spawn all around the valley.
I spent many levels there for all the above reasons. If you are just after the ore, but sure to expand your search to the snow yeti area as well, including around the side of the mountain. There’s only one problem with this area, everyone and their pet gerbil knows about it. A lot of players make regular rounds looking for ore. But if your lucky or play during off hours you can dig up a fair amount of ore.
