Copper Ore farming

Copper Ore is the lowest level ore that you can farm. It comes from Copper Veins and mostly found at the starting areas and in lower level zones.
There is not much difference between the zones where you can farm Copper Ore, but the zones listed below are slightly better than the other alternatives. If you are below level 20, you should stay at the zone where you are questing currently, there will be plenty of Copper Ore there.

Copper Ore

Durotar - Horde

Durotar is an excellent place to farm Copper Ore, there are a few caves in this zone and usually there are 3-4 Copper Veins inside those caves.

Darkshore - Alliance

Darkshore is the best place for Alliance players. Even Horde players can go there with flying mount. I was able to get 200 Copper Ore with just one lap in this zone.
