The Dark Ore

Objectives
Bring 5 Ore Samples to Bouldercrag the Rockshaper at Bouldercrag's Refuge.
 * Dark Ore Sample (5)

Description
At the Frozen Mine in the western part of the Snowdrift Plains, the stormforged iron dwarves have constructed a mine manned by slaves.

It's well behind the lines, so we haven't been able to find out much about what's going on there, but my scouts have reported seeing them remove cartloads of dark, sickly looking ore.

Progress
What have you discovered about the ore?

Completion


That ore... I can't touch it. It seethes with unnatural energy. No creature of stone can handle it. What do they mean to do with it?
