How does the amount of uranium identified at the deposit in Pittsylvania County compare to U.S. uranium reserves


Comments from KM:  Paul Robinson concludes, "No basis for a statement that VUI uranium resources approach one-quarter of U.S. uranium reserves is available from DOE EIA data."
Robinson debunks Millican's statement (see articles below). Robin Millican, of the market-oriented Institute for Energy Research in Washington, D.C., said Virginia has an estimated 100 million pounds of uranium – more than one quarter of all known U.S. reserves.
 
 
 
 
 
How does the amount of uranium identified at the deposit in Pittsylvania County compare to U.S. uranium reserves?

 A March 20, 2013 posting about uranium in Virginia includes the statement,

            Robin Millican, of the market-oriented Institute for Energy Research in Washington, D.C., said Virginia has an estimated 100 million pounds of uranium – more than one quarter of all known U.S. reserves,” without attribution. See  http://watchdog.org/75723/uranium-mining-heats-up-va-governors-race/.

 How accurate is that statement and where can U.S. Uranium Reserve estimates be found?

 An appropriate sources for the estimation of U.S. uranium reserves is the Department of Energy (DOE) Energy Information Administration (EIA) that keeps on a range of energy related matters including U.S. and state-by-state uranium reserves. DOE EIA’s  most recent report, published in 2010 from industry sources, is available at http://www.eia.gov/cneaf/nuclear/page/reserves/ures.html
 
The DOE EIA Report presets uranium reserves by state in the table as follows:

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 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. Sources: Estimated by Energy Information Administration, Office of Coal, Nuclear, Electric and Alternate Fuels, based on company reports, industry conferences, and U.S. Department of Energy, Grand Junction Office, files.
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  As the table shows, Virginia reserves identified by DOE EIA are a small fraction, much less than one-quarter, of U.S. uranium reserves in all categories identified by DOE EIA.

The table identified uranium reserves in two cost categories, “forward-cost $50/lb” and “forward-cost $100/lb.”

In the $50/lb category, total U.S. uranium reserves are reported as 539 million pounds.
 
Reserves in the “Other” state category that explicitly includes Virginia are reported as 50 million pounds, less than 10% -  about 9.2% - of the U.S. total. Attributing all of the “other” state uranium to Virginia is undoubtedly an over-estimate as it allows all of the “Other” state uranium to be counted as Virginia reserves even though “Other” states includes Nebraska where a currently operating in-situ uranium mine is located that certainly contains a significant portion of the “Other” state uranium reserves.

In the $100/lb category, total U.S. uranium reserves are reported as 1,227 million pounds. Reserves in the “Other” state category that includes Virginia are reported as 154 million pounds, less than one-eighth – 12.2% - of the U.S. total. This estimate is undoubtedly an over estimate of the uranium resource in Virginia as it allows all of the “Other” state uranium to be counted as Virginia reserves even though “Other” states includes Nebraska were a currently operating in situ uranium mine is located that certainly contains a portion of the “Other” state uranium reserves. 

DOE EIA’s U.S. uranium reserve estimate can be compared to the amount of uranium identified in Pittsylvania County in technical reports prepared by the Virginia Uranium, Inc. (VUI) consultants.

 The often-stated total amount of all uranium resources identified at the Coles Hill deposit of 119 million pounds used in the 2011 National Academies of Science/National Research Council Study of Uranium Mining in Virginia (“NAS Study”) is based on a 2009 Virginia Uranium, Inc.
 
(VUI) Preliminary Economic Assessment prepared by VI consultants filed in accordance with Canadian Securities Administrator requirements for uranium resources estimation.
 
The Canadian uranium resources estimation methods are not directly comparable to the DOE EIA reserve estimation method.
 
The 2009 VUI consultant report relied on in the NAS study does not support the use of 119 million pounds as the mineable uranium resources as the deposit; that Report identifies the uranium “resource available for mining” as 63.3 million pounds, only 53% of the total VUI uranium resource reported.

The VUI “minable” resources, though larger than the “Other” state reserves reported by DOE EIA, is still only 11.7% of the total U.S. uranium reserves reported by DOE EIA for the lower cost, $50/lb.

If the total uranium resources reported by VUI of 119 million pounds - included the 47% determined not to be “mineable” by VUI consultants – is compared to the total U.S. uranium reserves in the higher, $100/lb., category; the total uranium resource identified by VUI is less than 10%  - 9.7% - of the total U.S. uranium reserves of 1,227 million pounds.

No basis for a statement that VUI uranium resources approach one-quarter of U.S. uranium reserves is available from DOE EIA data.
