The Alliance Needs More Copper Bars!

Objectives
Bring 20 copper bars to Sergeant Stonebrow at the airfield in Dun Morogh.
 * Copper Bar x20

Description
Back again ? Outstanding! We still need more stacks of copper bars if you can procure them for the Ahn'Qiraj war effort. Will you help us out?

Rewards
You will receive: Alliance Commendation Signet and Ahn'Qiraj War Effort Supplies

Progress
Back again, ? Outstanding! The bars you've provided thus far are really going to help out in making all sorts of things for the war. I know, for example, that the copper is going to be used for parts of the steam tanks that are being built, as well as in a small fleet of gyrocopters that we're planning to deploy if time allows.

Don't let the stacks here fool you though, we still need more copper bars if you can procure them for the Ahn'Qiraj war effort. Will you help us out?

Completion
Excellent work! Digging around for that copper and smelting it must have been quite an adventure. Unless you bought them at the auction house. Either way, it works for me. You are to be commended for your contribution to the war effort,. And please don't hesitate to bring me more copper bars if you have them.
