Could someone give advice on the best places to look for Khazad iron and gold in Moria? I've been through the Great Delving, Zelem-melek, Durin's Way and the Silvertine Loads and haven't found a single iron or gold deposit--just copper and tin. Does it just not spawn in those areas? Which of the other areas am I most likely to find it? This character is 56, so lower level is better!
TIA for your assistance!
