2013 HIGHLIGHTS

• The Company commenced a takeover bid to acquire all of the outstanding shares of Rockgate Capital Corp. (“Rockgate”) in exchange for shares of Denison. Denison is offering to exchange each Rockgate common share for 0.192 of a common share of Denison (“Rockgate Transaction”). On October 30, 2013, Denison amended its offer by extending the expiry date to November 18, 2013 and varying certain conditions relating to the granting of stock options and execution of retention agreements. Denison also agreed to reduce the minimum tender condition from 90% to 66 2/3%.

• The Company completed its summer exploration campaign involving 23,880 metres in diamond drilling, geophysical surveying and linecutting on nine properties in the Athabasca Basin.

• The Company reported several high grade intersections at the Phoenix deposit on the Wheeler River property including WR-525 which intersected 43.8% U₃O₈ over 12.0 metres for a grade times thickness product (“GT”) of 525.6 %m, the highest GT of any hole drilled to date on the Wheeler River property. Mineralization has also been intersected over a strike length of 330 metres at the 489 Zone.

• The Company’s third quarter earnings were negatively impacted by a $35,655,000 impairment charge taken against the Company’s Mutanga project located in Zambia.

• The Company closed a CAD$15.0 million ($14.4 million) private placement of common shares issued on a “flow-through” basis, which will fund its Canadian exploration programs through to the end of 2014.

• Denison completed the acquisition of a portfolio of assets (“Fission Arrangement”) from Fission Energy Corp. (“Fission”) which included its 60% interest in the Waterbury Lake uranium project, its interests in all other properties in the eastern part of the Athabasca Basin, Quebec and Nunavut, as well as its interests in two joint ventures in Namibia. A new mineral resource estimate for the J Zone deposit at the Waterbury Lake project was completed in accordance with the requirements of National Instrument 43-101 (“NI 43-101”) with estimates of 291,000 tonnes grading 2.00% U₃O₈ containing 12,810,000 pounds of U₃O₈. All of the mineral resource is classified as indicated and reported above a cutoff grade of 0.1% U₃O₈.

• Denison closed its plan of arrangement (“JNR Arrangement”) with JNR Resources Inc. (“JNR”) which increased Denison’s partial interests in five exploration properties to 100%, added seven exploration properties to Denison’s property portfolio in Saskatchewan and interests in two properties in Newfoundland.

RESULTS OF OPERATIONS

Revenues

• Services and Other

Revenue from DES for the three months and nine months ended September 30, 2013 was $2,397,000 and $6,750,000 compared to $2,080,000 and $7,245,000 in the same periods in 2012.

Revenue from the management contract with UPC for the three months and nine months ended September 30, 2013 was $404,000 and $1,244,000 compared to $416,000 and $1,286,000 in the same periods in 2012.

Operating Expenses

• Mining

Commissioning of the McClean Lake mill began in the second quarter of 2013 to prepare for processing of Cigar Lake ore. The Cigar Lake joint venture (“CLJV”) continues to pay nearly all of the expenses under the terms of a toll milling agreement. Denison’s share of operating costs for the three months and nine months ended September 30, 2013 totaled $276,000 and $749,000 compared to $906,000 and $2,165,000 for the three months and nine months ended September 30, 2012. Operating costs were lower in 2013 primarily due to lower expenditures on the Surface Access Borehole Resource Extraction (“SABRE”) program. The SABRE program costs are funded by the McClean Lake joint venture.

• Services and Other

Operating expenses include costs relating to DES amounting to $2,117,000 and $6,156,000 for the three and nine months ended September 30, 2013 compared to $1,992,000 and $7,078,000 for the same periods in 2012.

Mineral Property Exploration

Denison is engaged in uranium exploration and/or development on 66 projects in Canada, Zambia, Namibia and Mongolia, comprising an aggregate of 1,145,000 hectares. While the Company has material interests in uranium projects in Asia and Africa, its primary focus (49 projects, 597,000 hectares) remains in the Eastern Athabasca Basin, Canada.

Denison’s Projects in the Athabasca Basin

Exploration expenditures for the three months and nine months ended September 30, 2013 were $4,850,000 and $12,061,000 compared to $3,269,000 and $10,685,000 for the same periods in 2012. The increase in expenditures for the three months and nine months ended September 30, 2013 is primarily due to increased spending on the Canadian properties offset by reduced spending on the Zambian and Mongolian properties.

• Canada

Denison’s share of exploration spending on its Canadian properties totaled $4,295,000 and $10,774,000 for the three months and nine months ended September 30, 2013 compared to $1,206,000 and $5,024,000 for the same periods in 2012.

At the Phoenix deposit, eight drill holes were completed in the summer program at Zone A to evaluate the potential for extensions of higher grade mineralization beyond the limits of the higher grade domain established for the January 2013 mineral resource estimate. Five of these drill holes encountered higher grade mineralization, with drill hole WR-525 being particularly significant. The results suggest that further efforts to extend higher grade mineralization are warranted. Areas to be targeted include both the western and eastern margins of Phoenix Zone A.

Ten of the 23 summer program drill holes were completed on wide spaced (300 metre) fences at the 489 Zone. Only drill hole WR-518 returned significant mineralization and it extended the strike length of known mineralization at the 489 Zone to 330 metres. However, the alteration system and structural package in the basement continues beyond the area drilled and will be followed up in future drill programs.

Additionally, four drill holes were completed in the Phoenix North area and one was completed at the REa area. No significant mineralization was encountered in these drill holes. Faulted graphitic pelitic rocks with significant sandstone alteration and anomalous geochemistry continue to be observed in the Phoenix North area, and drill targets remain there.

Other Properties

Summer Exploration Programs

Waterbury Lake – Linecutting and geophysical (DC-resistivity) surveying was completed along trend northwest of the J-Zone uranium deposit at Waterbury Lake. An initial interpretation suggests that the area has geophysical features that are analogous to the J-Zone and Midwest deposits. A six hole diamond drilling program was completed to follow up on the results. Some significant alteration and structure in both the sandstone and basement was observed in some of the drill holes. Geochemical analyses are still pending.

In the third quarter of 2013, Denison filed a mineral resource estimate for the newly acquired J Zone deposit at the Waterbury Lake project, in accordance with the requirements of NI 43-101. The estimate includes indicated resources of 291,000 tonnes grading 2.00% U₃O₈, containing 12,810,000 pounds of U₃O₈ above a cutoff grade of 0.1% U₃O₈.

Packrat – A six hole diamond drilling program on structural/geophysical targets at the Packrat property was completed. Weakly elevated radioactivity was encountered in basement rocks associated with alteration and faulting in two of the drill holes. Geochemical analyses confirm that the radioactivity is due to uranium. The highest value was 0.16% U₃O₈ over 0.3 metres in drill hole PR-13-06.

South Dufferin – Ten short diamond drill holes were completed on geophysical targets at this property located along the south rim of the Athabasca basin. No significant mineralization was intersected, although several shear zones in the basement rocks were encountered that confirm the presence of the Dufferin Lake fault system through the property.

Bachman Lake, Crawford Lake and Moon Lake – Drilling of six holes at Bachman Lake, Crawford Lake and Moon Lake is complete and was conducted as a combined program due to their close proximity. Significant alternation and structure in the sandstone and basement was observed at Bachman Lake and Crawford Lake, but not at Moon Lake. Geochemical analyses are still pending. International Enexco Limited funded the Bachman Lake drilling and, as a result, earned a 20% interest in that property.

Johnston Lake, Gumboot Lake – Since Gumboot Lake is adjacent to the Johnston Lake project, the summer program was conducted as a combined program. DC-resistivity geophysical surveying was completed and was followed up with a recently completed six hole drilling campaign. Weakly elevated radioactivity was encountered at Johnston Lake associated with alteration and structure adjacent to the unconformity. Geochemical analyses are pending.

Winter Exploration Programs

Hatchet Lake – A total of 2,370 metres of exploration drilling was completed in 13 drill holes. Uranium mineralization was intersected at the unconformity in two drill holes on the Crooked-Richardson Lakes trend. The best result was in drill hole RL-13-16, which intersected 0.45% U₃O₈ over 2.3 metres beginning at 124.0 metres down the drill hole. Further drilling is required to follow up on these results.

Moore Lake – A total of 5,110 metres of exploration drilling was completed in 12 drill holes. While no significant mineralization was intersected, several target areas require further exploration and Moore Lake remains a high priority property. Geophysical surveying was completed following the drill campaign.

Wolly and McClean Lake – At the AREVA Resources Canada Inc. operated Wolly and McClean Lake projects, a total of 6,450 metres of exploration drilling was completed in 34 drill holes. No significant mineralization was intersected.

Geophysical surveys were also completed on Bell Lake, Murphy Lake, and Stevenson River.

Zambia

Exploration expenditures of $461,000 and $796,000 for the three months and nine months ended September 30, 2013 were incurred on the Company’s Mutanga project in Zambia compared to $1,754,000 and $2,530,000 for the same periods in 2012. Soil geochemical surveying and radon sampling programs that started at Mutanga in February 2013 have now been completed. Several anomalies are worthy of follow-up programs. A 1,900 line-kilometre helicopter-borne electromagnetic geophysical survey was also completed and successfully mapped key rock types and faults on the property.

In the third quarter of 2013, a mineral resource estimate for the Mutanga project was completed, combining the Mutanga, Dibwe, and Dibwe East deposits into a single resource estimate, in accordance with NI 43-101. The combined resource estimate includes measured and indicated resources of 10,280,000 tonnes grading 0.034% U₃O₈ containing 7,800,000 pounds of U₃O₈ and inferred resources of 65,200,000 tonnes grading 0.029% U₃O₈ containing 41,400,000 pounds of U₃O₈.

Mongolia

Exploration expenditures on the Company’s GSJV properties in Mongolia totaled $94,000 and $491,000 for the three months and nine months ended September 30, 2013 compared to $309,000 and $3,131,000 for the same periods in 2012. Exploration activities have been reduced in 2013, as the Company focuses on completing the field programs and studies necessary to convert the Company’s exploration licenses to mining licenses. By comparison, the Company completed a 29,600 metre drill program on the Urt Tsav and Ulziit properties in 2012.

The Company has recently started exploring strategic alternatives regarding its ownership interest in the GSJV. The Company currently has an 85% interest in the GSJV, with Mon-Atom LLC holding the remaining 15% interest.

Namibia

Minor expenditures were completed by joint venture partner Rio Tinto on the Dome property in preparation for a 2,000 metre, seven hole diamond drilling program which commenced in October 2013.

General and Administrative

General and administrative expenses totaled $1,965,000 and $5,917,000 for the three months and nine months ended September 30, 2013 compared with $1,914,000 and $6,744,000 for the same periods in 2012. General and administrative expenses consist primarily of payroll and related expenses for personnel, contract and professional services, stock option expense and other public company expenditures. The decrease in general and administrative expenditures in the nine months ended September 30, 2013 is largely due to decreases in share-based compensation and personnel costs from the implementation of various staff reduction plans late in 2012 and early 2013.

In light of the implied valuations associated with recent market transactions involving companies with uranium projects in Africa and in conjunction with regular reviews of the exploration and development plans for the Company’s portfolio of mineral property assets, the Company completed an impairment test on its Mutanga project in Zambia. Since the Mutanga project’s recoverable amount was determined to be lower than its carrying amount, the Company has recognized an impairment loss of $35,655,000 in the three months ended September 30, 2013.

Other Income and Expenses

Other income (expense) totaled ($3,274,000) and ($2,874,000) for the three months and nine months ended September 30, 2013 compared with ($4,508,000) and ($4,133,000) for the same periods in 2012. The decrease in other expenses for the three months ended September 30, 2013 is primarily due to a $1,212,000 gain from the sale of an overriding royalty on an oil property in Italy. The decrease in other expenses for the nine months ended September 30, 2013 is primarily due to income from the sale of the overriding royalty and a $1,061,000 decrease in foreign exchange losses, offset by $1,103,000 in losses on equity investments.

Discontinued Operations

On June 29, 2012, the Company sold its U.S. Mining Division to EFR. In exchange, consideration equal to 425,440,872 EFR common shares was received and distributed to Denison shareholders of record on June 29, 2012 (the “EFR Transaction”).

As a result of the EFR Transaction, Denison has accounted for its U.S. Mining Division as a discontinued operation.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $27,867,000 at September 30, 2013 compared with $38,188,000 at December 31, 2012. The decrease of $10,321,000 was primarily due to cash used in operations of $17,071,000, cash used in investing activities of $6,542,000, and an unfavourable foreign exchange impact of $616,000, offset by cash provided by financing activities of $13,908,000.

Net cash used in operating activities of $17,071,000 in the nine months ended September 30, 2013 is comprised of net loss for the period adjusted for non-cash items and changes in working capital items. Significant changes in working capital items during the period include an increase of $593,000 in trade and other receivables and a decrease of $641,000 in reclamation obligations.

Net cash used in investing activities of $6,542,000 consists primarily of $4,058,000 spent in connection with the Fission Arrangement, $1,769,000 spent on property, plant and equipment expenditures, and $715,000 spent in connection with the JNR Arrangement.

Net cash from financing activities totaled $13,908,000, primarily due to the issuance of common shares on a “flow-through” basis, net of issue costs.

On June 27, 2013, the Company extended the maturity date of its $15,000,000 revolving term credit facility (the “Credit Facility”) from June 28, 2013 to January 31, 2014. The Credit Facility contains a covenant to maintain a certain level of tangible net worth, which must be greater than or equal to the sum of $230,000,000 plus an amount equal to (i) 50% of each equity issue from and including March 31, 2012 and 50% of positive net income in each fiscal quarter from and including March 31, 2012. At September 30, 2013, the Company is in compliance with its facility covenants and there is no debt outstanding under this facility; however, $9,413,000 of the line was used as collateral for certain letters of credit.

The Company has provided an unlimited full recourse guarantee and a pledge of all of the shares of Denison Mines Inc. (“DMI”). DMI has provided a first-priority security interest in all present and future personal property and an assignment of its rights and interests under all material agreements relative to the McClean Lake and Midwest projects. The Credit Facility is subject to a standby fee of 1%.

SUBSEQUENT EVENTS

On September 19, 2013, Denison formally commenced a takeover bid to acquire all of the outstanding shares of Rockgate in exchange for shares of Denison. Denison is offering to exchange each Rockgate common share for 0.192 of a common share of Denison. Rockgate’s key asset is its Falea project located in Mali, Africa.

On October 30, 2013, Denison amended its offer by extending the expiry date to November 18, 2013 and varying certain conditions relating to the granting of stock options and execution of retention agreements. Denison also agreed to reduce the minimum tender condition from 90% to 66 2/3%.

Using Rockgate’s outstanding shares at September 30, 2013 of 116,897,470 shares, the above share exchange ratio of 0.192 and Denison’s closing share price at September 30, 2013 of $1.08 per share, the offer values Rockgate at approximately $24,240,000 excluding transaction costs incurred by Denison.

OFF-BALANCE SHEET ARRANGEMENTS

The Company does not have any off-balance sheet arrangements.

OUTLOOK FOR 2013

The Company’s exploration, development and operation plans for Canada, Zambia and Mongolia are largely complete for the year with the Company on track to finish the year on budget:

(in thousands)	Original Budget			Revised Budget			Spend to September 30, 2013 (2)
Canada – Mining
Exploration	$	9,900	(1)	$	12,100	(1)	$	10,771

¹  Budget figures have been converted using a US$ to CAD$ exchange rate of 1.0000.

²  Represents a non-GAAP measure and excludes non-cash depreciation and amortization amounts of $400,000.

Canada

• Mineral Property Exploration

With the addition of several new properties from the Company’s acquisition of Fission, the Company increased its exploration budget for 2013. Based on the revised budget, Denison is expecting to spend $12,100,000 on Canadian exploration during 2013, as compared to the originally announced budget of $9,900,000.

• Development/Operations

Approximately $3,500,000 (Denison’s share $814,000) is expected to be spent on the Midwest and McClean Underground development stage projects and the SABRE program for 2013. The majority of the expenditures relate to the evaluation of the 2012 SABRE test program, the design of a semi-commercial field program for 2014, and the preliminary evaluation of the use of the SABRE mining method for the Caribou deposit.

Commissioning of the McClean Lake mill began in the second quarter of 2013 in preparation for processing of Cigar Lake ore late in 2013. However, in September 2013, the CLJV announced that ore production at Cigar Lake would be postponed until the first quarter of 2014 with mill processing delayed until the second quarter of 2014. This will result in a decrease in Denison’s share of operating and capital expenditures in 2013, from $1,800,000 as originally budgeted to $1,100,000. Additionally, Denison has reduced its revenue projection for U₃O₈ sales and toll milling fees from $1,500,000 to $nil.

International

• As a result of various cost control measures implemented during the year, the Company reduced its Zambian program budget from $3,500,000 to $3,100,000 for 2013, and reduced its Mongolian program budget from $1,700,000 to $1,400,000 for 2013.

RISK FACTORS

There are a number of factors that could negatively affect Denison’s business and the value of Denison’s common shares, including the factors listed in the Company’s Annual Information Form dated March 13, 2013 available at www.sedar.com, and in the Company’s Form 40-F available at http://www.sec.gov/edgar.shtml.
