There are a few types of Thorium Veins you will encounter on these routes, small and rich. You must be mining skill 230 to mine the Small Thorium veins and mining skill 255 to mine the Rich Thorium Veins. If the reason you are mining is for gold then please take a look at this Gold Course which teaches you how to reach the gold cap.

The two zones I have chosen are Ungoro Crater and Burning Steppes which both have a mix of each of the Thorium veins.

Thorium Ore in Un’Goro Crater

The hotspots here are going to focus mainly on the outside walls of the zone and especially the cave in the Northeast Corner.  In the center you can find more Rich Thorium Veins but I often find that spot is not worth navigating, but if you want to venture up that way feel free to do so.  There is also a hive in the south that can sometimes be worth dropping in to say hi.

Thorium Ore in Burning Steppes

The Thorium in this zone is usually spread out pretty good, the best spot is going to be in the caves around the mountain in the east which I’ve marked with a V.
