WoW Tin Mining Guide

Here are The Noob School's top five zones for mining tin. If your character is a lower level check the levels to see what level mobs are found in each zone. Also, make sure your mining is at least 65 before you attempt to mine tin.
Where to Mine Tin in the Barrens

The Barrens: Levels 10-25



The tin mining route for the Barrens is very similar to the copper mining route in the Barrens because both tin and copper will be found in many of the same places. You could follow the copper mining route and probably get enough tin; however, this tin route focuses on some of the areas that are more commonly populated with tin.

Start out by going north of Ratchet into Boulder Lode Mine, proceed west toward the harpy areas in The Dry Hills. Go into the harpy areas and loop around the mountains inside their camp. Next travel southeast toward Wailing Caverns, ensure that you check the Lushwater Oasis south of Wailing Caverns. From the oasis head east to the The Stagnant Oasis and then wrap around the east side of the mountain range and head toward Northwatch Hold. From Northwatch Hold head west on the path and then south along the eastern mountain ridge. Perform a loop around Blackthorn Ridge, the quillboar camp in the very south of the zone, and head back into the path to repeat going whichever direction on the path you prefer.
Where to Mine Tin in Thousand Needles

Thousand Needles: Levels 24-35



The tin mining route for Thousand Needles is very simple. Perform a full loop of the outer edges of the entire zone and proceed into Shimmering Flats, if you can handle the mobs (up to level 35), if not just cut off your route before entering Shimmering Flats and continue onto the other side of the zone. Stay away from Highperch beasts because they will only slow down your mining time.
Where to Mine Tin in Hillsbrad Foothills

Hillsbrad Foothills: Levels 20-32



The area of focus in Hillsbrad Foothills should be Azurelode Mine, which is directly west of Southshore. Depending on what area you fly into, Tarren Mill or Southshore, hop onto the route and follow the route as indicated on the map. Stick to the northern mountains, the Azurelode Mine, Yeti Cave, and the stream and there will be an abundance of tin on this path.
Where to Mine Tin in Redridge Mountains

Redridge Mountains: Levels 15-25



This small circuit in the mountains north of Lakeshire is the most productive tin route available in the zone. Ensure that you enter all caves if you can handle the enemies, this route is full of gnolls around level 20 and orcs up to level 25, so be prepared. As an alternative you can run the mountains in a small loop in the southeastern part of the zone but I have not found it to be remotely as productive as the route in the northwest.
Where to Mine Tin in Duskwood

Duskwood: Levels 19-30



The major focus areas of this route are Roland's Doom, the nightbane infested cave, located in the southeastern part of the route and Vul'Gol Ogre Mound, the southwestern cave full of ogres. The rest of the route is to break boredom. There are tin veins around the outside mountain range of The Twilight Grove but they are not as frequent as either of the two caves, but if you cannot handle the caves then by all means use the full route on the map skipping the cave areas.
Where to Mine Tin in Instances

If you are looking for instances with tin you will find it in The Deadmines (15-20), Wailing Caverns (15-21), and Blackfathom Deeps (20-27)
