The Tooltip of the plan for the dig site says:
The Mine was once abandoned, but there are still underground riches ready to be discovered.
- Level 1: Allows players to mine Draenic Stone from mineral nodes in Draenor. Draenic Stone can be converted to work orders for Draenor minerals. 7 Work Orders
- Level 2: Allows followers with the Mining trait to work here, granting a unique bonus (adds mining carts). Also opens a new mineshaft, granting access to additional mining nodes. 14 Work Orders
- Level 3: A final mineshaft allows access to rich mining nodes. In addition, garrison guards will patrol your mine, keeping it clear of hostile Goren. 21 Work Orders.
It does not say what I actually get. Do I get resources or ore? If I get Ore, how much per day? What are the exact benefits?
I am Engineer so the Ore would be welcome, but I cannot harvest any ore since I am Jeweler with my second profession on my main character.
