The mines in Alterac Valley hold more than just minerals.  Both the Frostwolf and Stormpike have cached excess supplies in the Irondeep and Coldtooth mines... that's not a bad idea, if we could only maintain control of them!$B$BCapture a mine, then return to me.  To capture a mine, enter one that we do not control and kill its leader.  When you do that, the mine will be ours, and we'll send troops to protect it!
