U.S. Uranium Reserves Estimates

Data for: 2008 | Release Date: July 2010 | Next Release Date: Discontinued

The U.S. Energy Information Administration (EIA) has updated its estimates of uranium reserves for year-end 2008. This represents the first revision of the estimates since 2004. The update is based on analysis of company annual reports, any additional information reported by companies at conferences and in news releases, personal contacts, and expert judgment.

Table 1. U.S. Forward-Cost Uranium Reserves by State, Year-End 2008
State	$50/lb			$100/lb
State	Ore (million tons)	Grade^a (%)	U₃O₈ (million lbs)	Ore (million tons)	Grade^a (%)	U₃O₈ (million lbs)
Wyoming	145	0.076%	220	398	0.056%	446
New Mexico	64	0.140%	179	186	0.105%	390
Arizona, Colorado, Utah	22	0.145%	63	117	0.084%	198
Texas	15	0.089%	27	32	0.062%	40
Other^b	28	0.090%	50	95	0.081%	154
Total	275	0.098%	539	828	0.074%	1,227
^a Average percent U₃O₈ per ton of ore. ^b Includes Alaska, California, Idaho, Montana, Nebraska, Nevada, North Dakota, Oregon, South Dakota, Virginia and Washington. Notes: Uranium reserves that could be recovered as a byproduct of phosphate and copper mining are not included in this table. Reserves values in forward-cost categories are cumulative; that is, the quantity at $100 per pound U₃O₈ includes all reserves available up to and including that cost. Totals may not equal sum of components because of independent rounding.See EIA Glossary for definition of reserves."Reserves," as reported here, do not necessarily imply compliance with U.S. or Canadian government definitions for purposes of investment disclosure.
