Where to Mine Thorium in Winterspring
Winterspring: Levels 50-55
Winterspring is loaded with Thorium. There are lots of choices and strategies for you in this zone. You can stick to running the loop on the map or stick to the caves you find. You can even go off the route on the map if you’d like. You should have a lot of luck with this zone.
Where to Mine Thorium in Silithus
Silithus: Levels 55-60
The circuit you’ll be running (or flying) in Silithus is that of a large square. If that route is too boring for you there are tunnels/caves that you can go into, but you will have to fight mobs. This zone is another good place to farm Thorium Ore.
Where to Mine Thorium in Blasted Lands
Blasted Lands: Levels 55-60
The Blasted Lands is another good zone to collect Thorium in. You can travel the route on the map and find both Thorium and Rich Thorium Veins. Be sure to enter the cave in the northeast part of the route.
