We've sent warnings about the Fomors to each base, but Colhen's becoming more and more of a strategic location. We've been ordered to patrol the area more carefully. I entrust Hoarfrost Hollows to you. Try heading deeper in.
Area 1 Path 2 has 1. It is half way through the map, just before the gate that it opened by turning the capstan. The ore is between the 2 huts nearby.
Area 2 Path 2 has 1. It is in the first of the 2 large caverns, in the middle of the cavern.
Erg Pot: There is 1 in Area 2, Path 1 near the start of the area. The pot is sitting on a lower ledge to the right. Jump down through the opening in the fence to reach it.
