TORONTO, ONTARIO--(Marketwire - Feb. 27, 2012) - Denison Mines Corp. (TSX:DML)(NYSE Amex:DNN) ("Denison" or the "Company") is pleased to announce that it has recently completed a mineral resources estimate on its 100% owned Mutanga Project based on the results of its 2011 drill program, and this new estimate significantly expands the mineral resources at the Mutanga Project.
The new Dibwe East Inferred resource, located between the main Mutanga and Dibwe deposits was estimated as of February 24, 2012, in accordance with National Instrument 43-101 ("NI 43-101"), to be 39.8 million tonnes grading 322 ppm eU3O8, containing 28.2 million lbs. The Inferred resource is in accordance with CIM Definition Standards and is based on a cut-off grade of 100 ppm eU3O8.
Ron Hochstein, President and C.E.O. of Denison commented, "Several targets are yet to be tested to potentially further increase the resources. The 2012 drill program will focus on a number of these targets."
The resource estimated at the Dibwe East deposit represents a significant discovery of continuous uranium mineralization associated with known ore-bearing geologic sediments. The Dibwe East deposit consists of strata bound sedimentary uranium mineralization located in three stacked mineralized horizons extending from near-surface to depths of 130 meters.
In 2009, the Company filed a technical report for mineral resource estimates for the Mutanga Project. The following table provides a consolidated summary of the Measured, Indicated and Inferred mineral resource estimates for the Mutanga Project, including the Mutanga, Dibwe, Dibwe East, Mutanga Ext, Mutanga East and Mutanga West deposits.
Consolidated Mutanga Project Mineral Resource Estimates
|Lbs. U3O8 |
|Measured & Indicated||10.3||345||7.8|
The Dibwe East resource estimate has been prepared by Denison Mines (USA) Corp., a wholly owned subsidiary of Denison. Roscoe Postle Associates, Inc. ("RPA") was retained by the Company to independently review and verify the Dibwe East mineral resource estimate. The resource estimate is based on 237 holes totaling 21,729 meters of reverse circulation and diamond drilling carried out by Denison from 2008 through 2011 on roughly a 100 metres x 200 metres grid with 100 metre drill hole spacing along profiles. Equivalent % U3O8 ("e%U3O8") is based on radiometric gamma probing and not chemical assays. Radiometric assays have been corrected for disequilibrium based on comparison with chemical assays in core holes. The Technical Report presenting these mineral resource estimates will be filed on SEDAR (www.sedar.com) within 45 days of this release.
The technical information contained in this press release regarding the Dibwe East deposit has been prepared and verified by Mr. Mark Mathisen, P.G., Senior Project Geologist at Denison Mines (USA) Corp, who is a "Qualified Person" as defined in NI 43-101, and has been reviewed by William E. Roscoe, Ph.D. P.Eng. of RPA, who is an independent "Qualified Person" as defined in NI 43-101.

This information speaks only as of the date of this press release. In particular, this press release may contain forward-looking information pertaining to the following: the estimates of Denison's mineral reserves and mineral resources; estimates regarding Denison's uranium and vanadium production levels and sales volumes; capital expenditure programs, estimated production costs, exploration and development expenditures and reclamation costs; expectations of market prices and costs; supply and demand for uranium and vanadium; possible impacts of litigation and regulatory actions on Denison; exploration, development and expansion plans and objectives; Denison's expectations regarding raising capital and adding to its mineral reserves and resources through acquisitions and development; and receipt of regulatory approvals, permits and licences and treatment under governmental regulatory regimes.
There can be no assurance that such statements will prove to be accurate, as Denison's actual results and future events could differ materially from those anticipated in this forward-looking information as a result of those factors discussed in or referred to under the heading "Risk Factors" in Denison's Annual Information Form dated March 28, 2011, available at http://www.sedar.com, and in its Form 40-F available at http://www.sec.gov, as well as the following: global financial conditions, the market price of Denison's securities, volatility in market prices for uranium and vanadium; ability to access capital, changes in foreign currency exchange rates and interest rates; liabilities inherent in mining operations; uncertainties associated with estimating mineral reserves and resources and production; uncertainty as to reclamation and decommissioning liabilities; failure to obtain industry partner and other third party consents and approvals, when required; delays in obtaining permits and licenses for development properties; competition for, among other things, capital, acquisitions of mineral reserves, undeveloped lands and skilled personnel; public resistance to the expansion of nuclear energy and uranium mining; uranium industry competition and international trade restrictions; incorrect assessments of the value of acquisitions; geological, technical and processing problems; the ability of Denison to meet its obligations to its creditors; actions taken by regulatory authorities with respect to mining activities; the potential influence of or reliance upon its business partners, and the adequacy of insurance coverage.

"Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves. United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable.
