Copper - Worth its Weight in Gold

Copper is one of the easiest to find minerals in World of Warcraft and yet even with the Burning Crusade it can sell for more than enough on the Auction House. It may seem a bit obvious to point out but a lot of people don't realise exactly how much can be made. With a swift mount and the +10% riding crop increase you can speed around the copper spawn points, and an addon like gatherer will greatly speed your grinding to up your gold.

I would definately suggest any miner to spend a bit of time grinding copper to get easy gold in WoW!
