Thorium is a radioactive metal that occurs naturally in soil, water, and rocks. It's also used in nuclear reactors, welding rods, and ceramic glazes.
It's three to four times more abundant than uranium

More than 200 thorium-rich veins in the Beaverhead Mountains form the Lemhi Pass district, Idaho and Montana. This district is thought to contain the largest concentration of thorium resources in the United States and is the site of renewed thorium exploration activity.

Endless thorium supply in China can help make unlimited nuclear power: Survey
With a half-life of over 14 billion years, that would indeed be quite a find. But it's a much weaker isotope than uranium and costs a LOT more to extract, so I wonder just how much of a "wonder fuel" it could be?
