Colorado's Uranium Reserves
The US Energy Information Administration updated its Uranium Reserve estimates in 2010. Colorado was lumped in with Utah and Arizona.
The three states are estimated to have about 200 million pounds of U3O8 at a price of $100 per pound. The price is currently hovering around $60 per pound, but reached $140 per pound in 2007. From 1989 to 2004, the price averaged about $10 per pound.
The three-state group is third in the nation behind Wyoming and New Mexico.
