A new global breakdown of identified uranium resources shows just three countries, Australia, Kazakhstan and Canada, control more than half of the world's known supply. Total identified recoverable uranium resources reached 5.9 million metric tons in 2023, the most recent year with complete data, up more than 25 percent over the past decade as exploration activity has accelerated alongside renewed interest in nuclear power.

Australia holds the largest share by a wide margin, with 1.7 million metric tons of contained uranium, or 28 percent of the global total, more than double the amount held by second ranked Kazakhstan at 814,000 metric tons. Canada rounds out the top three with 582,000 metric tons. Namibia and Niger each hold significant African reserves at 498,000 and 336,000 metric tons, while Russia holds 477,000 metric tons.

The United States, by comparison, holds an identified 68,000 metric tons, a small fraction of the global total despite being one of the largest consumers of uranium for nuclear fuel. That gap between domestic resources and consumption underpins the federal government's recent push to secure long term supply agreements and expand domestic enrichment capacity, since raw uranium resources and enrichment capability are separate links in the fuel supply chain. The data, compiled from the OECD Nuclear Energy Agency and International Atomic Energy Agency, covers resources recoverable at costs up to $130 per kilogram of uranium.
