Uranium Reserves by Country 2025

Infamous more than famous, Uranium is well-known because of its use in nuclear power. It can fuel nuclear reactors, generating electricity and powering Navy vessels. Nuclear weapons are another major use of the mineral, which makes it a little scary that it is so relatively common to find.

The problem is that even though it is common, it tends to be spread out over large areas. Obviously, this presents an issue as it makes mining the Uranium potentially costly. Because of this, Uranium measurements are qualified by the cost of recovery. Basically, this means we understand how much uranium we can actually access based on the cost of extraction.

Australia has the most Uranium of any country in the world. At a cost of $260/k, Australia has 1.95 million tons of Uranium. At half that price point, $130/kg, Austria still has 1.68 million tons. Kazakhstan and Canada both have similar amounts of uranium at $260/kg: 874 thousand for Kazakhstan and 865 thousand for Canada. However, Kazakhstan has easier access to its Uranium; it can access 815 thousand tons at $130/kg while Canada can only access 588 thousand.

Russia and Namibia round out the top five, both with over half a million tons accessible at $260/kg. However, at $130/kg, both Russia and Namibia drop under 500 thousand tons of Uranium. Famous lover of nuclear weapons, the United States lands somewhere in the middle with 112 thousand tons of Uranium at $260/kg but only 59 thousand at $130/kg.

At the bottom of the list is Senegal with 1.1 thousand tons of Uranium accessible at $260/kg. Finland has slightly more at 1.2 thousand tons, but all of it is available at $130/kg. Zimbabwe and Chile both have 1.4 thousand tons at $260/kg. Egypt, Chad, Vietnam, Paraguay, and Guyana all have less than 5 thousand tons, and Mexico rounds out the bottom ten countries with exactly 5 thousand tons.
