Denison Mines Reports Second Quarter Results

TORONTO, ONTARIO--(CCNMatthews - Aug. 10, 2006) - Denison Mines Inc. (TSX:DEN) -

Not for distribution to United States newswire services or for dissemination in the United States

Denison Mines Inc. today reported its financial results for the three months and six months ended June 30, 2006. All amounts in this release are in Canadian dollars unless otherwise indicated.

Consolidated net earnings were $539,000 or $0.02 per share for the three months and $545,000 or $0.02 per share for the six months ended June 30, 2006. This compares with consolidated net earnings of $2,519,000 or $0.10 per share for the three months and $1,098,000 or $0.04 per share for the six months ended June 30, 2005. The 2006 results are after expensing exploration costs of $1,360,000 for the three months and $2,803,000 for the six months in 2006 compared to $571,000 and $938,000 expensed for exploration costs in the same periods in 2005.

Cash flow from (used in) operations, after funding of exploration expense, was $4,746,000 for the three months and $7,296,000 for the six months ended June 30, 2006 compared to ($2,387,000) for the three months and $552,000 for the six months ended June 30, 2005. On a fully diluted per share basis, cash flow from operations was $0.15 for the three months and $0.25 per share for the six months ended June 30, 2006 compared to ($0.09) and $0.02 for the same periods in 2005.

Revenue was $11,349,000 for the three months and $16,857,000 for the six months ended June 30, 2006 compared with $12,281,000 and $15,464,000 for the comparable periods in 2005.

Significant events in the second quarter include:

- Sales of U3O8 for the quarter were 222,500 pounds which represents about 23% of our expected annual sales volume. Average sales price for the quarter was US$36.23.

- Production of U3O8 at the McClean Lake processing facility was 382,000 pounds of which Denison's share was 86,000 pounds. As a result of the lower volumes, unit production costs have increased significantly and are expected to average $12.00 per pound higher in 2006 compared to 2005.

- The blind boring/jet boring program has proceeded more slowly than anticipated but the first three holes have been completed to just above the ore body and extraction of the ore is expected to commence in a few weeks. As a result, Denison expects the full year production at McClean to be reduced to about 3,000,000 pounds.

- The spot price of U3O8 continued to increase and was US$45.50 at June 30, 2006, an increase of 57% from the June 30, 2005 level of US$29.00. The stronger Canadian dollar reduced the impact of the price increases as exchange rates were $1.1162 at June 30, 2006 compared to $1.2254 at June 30, 2005.

- Follow-up drilling at Wheeler River by WR-214 intersected 3.8 metres of 0.857% eU3O8 at an approximate depth of 300 metres below the surface at the unconformity.

- Continued strong mineralization of 3.8 metres of 4.1% eU3O8 was intersected from a recently started summer drill program at the Mae Zone on the Midwest property.

- Mining of the Sue E pit continued with first ore anticipated to be reached in September.

- On June 13, 2006, Denison announced a normal course issuer bid to acquire for cancellation up to 2,000,000 of its common shares through the TSX. The bid commenced on June 20, 2006 and will terminate on June 19, 2007. At June 30, 2006, Denison had purchased and cancelled 200,000 common shares.

Uranium Production

The uranium production segment recorded earnings of $2,245,000 for the three months and $3,617,000 for the six months ended June 30, 2006 compared to $3,736,000 for the three months and $3,589,000 for the six months ended June 30, 2005.

The decrease in earnings of the segment for the quarter versus the comparable period last year was the result of lower sales volumes, increased cost of goods sold due to lower production volumes and Canadian/US dollar exchange rates that were unfavourable compared to last year offset in part by higher average sales prices.

Sales in the quarter were 222,500 pounds U3O8 versus 395,000 pounds in the second quarter last year. Sales for the year to date in 2006 are 345,000 pounds (35% of expected annual sales) compared to 493,000 pounds (38% of sales) for the comparable period in 2005. US dollar sales prices for the quarter averaged US$36.23 versus US$22.12 in the second quarter 2005. US/Canadian dollar exchange rates averaged $1.112 in the second quarter of 2006 compared to $1.228 in the same period last year. The resulting average sales price in Canadian currency was $40.29 for the second quarter in 2006 versus $27.17 for the same period last year. Denison's uranium sales in 2006 will be under contracts with various durations and which contain a variety of pricing formulas. Uranium sales in 2006 are contracted at about 1,000,000 pounds U3O8. About 33% of these volumes will be sold under legacy contracts at prices well below current market. The balance will be sold at prices in excess of US$30.00 per pound resulting in realized average US dollar prices being significantly higher than in 2005. Timing of delivery under these contracts is at the option of the customer. Denison expects its sales volumes for the year to be apportioned 12%, 23%, 52% and 13% in the first, second, third and fourth quarters.

The McClean Lake Joint Venture produced 382,000 pounds of uranium during the three months ended June 30, 2006 compared with 1,562,000 pounds during the same period in 2005. Denison's 22.5% share of production totaled 86,000 pounds during the second quarter 2006 compared to 351,000 pounds in the comparable period in 2005. The primary reasons for lower production in the quarter were lower grade ore feed, reduced throughput caused by variances in the arsenic concentration of the ore feed that resulted in elevated temperatures in the leach circuit and a shortage of reagents, primarily hydrogen peroxide, due to road closures caused by forest fires. To address these problems, one of the storage pachucas is being converted into an additional leach tank to increase throughput capacity and cooling coils are being added to most of the leach tanks to control the high temperatures caused by the high arsenic content. These process improvements are expected to be operational in the third quarter. Average mill feed grade for the second quarter 2006 was 0.68% U3O8 compared to 1.59% U3O8 for the comparable 2005 period.

Unit cost of goods sold increased by $12.00 per pound in the quarter and $10.00 per pound in the six months in 2006 compared to the same period last year due to the lower volumes produced. Unit production costs for the year are expected to average about $12.00 per pound higher than average production costs in 2005. This increase is expected to be reduced by about $2.00 per pound with the addition of a ferric sulphate plant, scheduled to go into service in late 2006 and substantially eliminated when processing of Cigar Lake ores begins in early 2008.

Production for the year is now expected to be about 3,000,000 pounds U3O8 of which Denison's share will be about 675,000 pounds. Actual production levels will depend on the quantity, quality and grade of ore available from mining activities during the year. Mining of the Sue A deposit was completed in the first quarter of 2006 and mining of the Sue E deposit is currently underway and will continue throughout 2006 and 2007. Processing of the ore from Sue A is underway. It is expected that ore from the Sue E deposit will be available in September 2006. The extraction of ore from the McClean North deposit using the "blind-boring/jet boring" technique is expected to commence in the next few weeks. Production will also come from the remainder of the Sue C stockpile. The ability of the operator to recover the high-grade ore contained in the stockpiles will impact actual production levels.

AREVA is planning to undertake an infill drilling program this September to determine if over 7,000,000 pounds of mineralization below and south of the planned Sue E pit, currently in inferred resources, can be brought into the reserve category and incorporated into the Sue E mining plan.

Construction on the expansion required to receive and process ore from Cigar Lake is expected to be complete by the end of 2006. Processing of the Cigar Lake ores is now not expected to commence until early 2008 subject to the Cigar Lake Joint Venture obtaining the required regulatory approvals.

Uranium Exploration (1)

Denison is engaged in uranium exploration as part of the McClean and Midwest joint ventures and as a participant in joint ventures in Saskatchewan at Wheeler River, Wolly, Waterfound, Russell Lake and in Mongolia. Through its joint ventures with industry leaders AREVA and Cameco, Denison maintains a significant land interest in the most geologically prospective part of the southeast part of the Athabasca basin. Denison's share of exploration spending totaled $1,571,000 for the three months and $3,196,000 for the six months ended June 30, 2006 compared to $724,000 and $1,240,000 for the comparable periods in 2005. Of these amounts, $1,360,000 and $2,803,000 was expensed for the three months and six months ended June 30, 2006 and $571,000 and $938,000 was expensed for the comparable periods in 2005, as the spending related to exploration on properties without ore reserves. The 2006 year-to-date exploration expenditures included $393,000 at the McClean and Midwest properties, $1,594,000 at Wheeler, $535,000 at Wolly, $64,000 at Waterfound, $66,000 at Russell Lake and $386,000 in Mongolia.

Denison's share of exploration spending for 2006 is expected to total about $5,500,000 of which $3,100,000 will be spent at the Wheeler River uranium project where Denison is the operator. Denison also expects to spend over $800,000 at the Wolly uranium project. The balance of the exploration spending will be at Midwest, McClean Lake, Waterfound, Russell Lake and in Mongolia. The majority of the exploration spending will be expensed during the year.

All of Denison's exploration projects are located in the prolific southeast part of the Athabasca basin with proximity to existing, licensed mills. All are currently the subject of significant exploration activity, either by Denison or its joint venture partners as operator. At the 40% owned Wheeler River Joint Venture, where Denison is operator and is earning a further 20% interest to total 60% by funding expenditures to $7,000,000, diamond drilling continued through the summer. The Wheeler property contains similar geological conditions to that of McArthur River, and the quartzite ridge remains a high-priority target. As previously announced, WR-204, the last hole drilled in 2005, intersected the first uraniferous intersection associated with the strongly geochemically altered quartzite ridge. Follow up drilling this summer, by WR-214, located 10 metres along a fence to the northwest, intersected 3.8 metres of 0.857% eU308, based on downhole radiometric probing, at an approximate depth of 300 metres below surface at the unconformity. Diamond drilling is currently testing targets on the east side of this quartzite ridge, and further work is planned on the WR-214 zone in the fall.

At the 22.5% owned McClean Project, a limited drill program has been completed on the newly discovered Bena Lake zone. Ten holes were drilled to test the faulted unconformity contact, and while all holes returned elevated radioactivity on the basis of down hole radiometric probing, at either the unconformity or in the basement, no significant intersections were made. Two drill holes tested the east strike extension of the JEB conductive zone with no significant results. The rig has now moved to the Midwest Project to aid in testing the Mae zone this summer.

At Midwest, a 25.17% owned project operated by joint venture partner AREVA, a two rig drill program is currently underway, testing the west extension of the Mae Zone. Work by operator AREVA this past spring, and previously disclosed by Denison, has identified a crosscutting zone of mineralization, at least 280 metres in length. At least three closely spaced and parallel mineralized structures are present, and mineralization is present in the sandstone, unconformity and basement. Depths to the unconformity are approximately 220 metres or the same as the main Midwest deposit, slated for stripping in 2008. While the high-grade part of the zone remains open to the east, the western part, accessible by land, is currently the subject of a two rig, $1,000,000 program. Five holes have been completed to date, and all have been strongly altered, but encountered zones of significant core loss. Drill hole MW-697 has intersected a reported 4.1% eU3O8 over 3.8 metres, based on downhole radiometric probe calculations. This hole is drilled on a line 200 metres grid west of previously disclosed hole MW-692 which intersected 12.4% eU3O8 over 6.1 metres. The zone remains open to the grid west and one rig will shortly move to the next fence, 25 metres to grid west, to continue to test this strike extension. The thickness and dimensions of the zone remains to be determined. The Mae zone will be the subject of an intensive two rig diamond drill program, primarily based from the ice during the winter of 2007, and the current work will aid in the identification and prioritization of targets.

Field work on the Wolly project, where Denison can earn a 22.5% interest by funding exploration expenditures to $6,000,000, has been completed for the year. Diamond drilling carried out by operator AREVA targeted crosscutting features identified by a ground resistivity survey. While a number of crosscutting structures were identified in drill core, validating the geophysical interpretation, no significant economic results were obtained. However, the prospectiveness of this region, along strike from the past producing JEB deposit, warrants additional work expected to be undertaken in 2007. The Wolly project is one of the largest properties in the Athabasca basin, at approximately 30 by 8 kilometres and located along the southeast margin, and is expected to play an increasingly prominent role in Athabasca exploration as work accelerates on this underexplored property.

The grades from both the new Wheeler and Midwest holes are equivalent eU308 grades based on downhole radiometric probing. In the case of the Mae drill hole at Midwest, results are at a cutoff grade of 0.1% U3O8 as reported by AREVA, and geochemical corroborative assay results have not been completed on this recently drilled hole. However, these radiometric probes are industry standard procedures for determining downhole uranium grades and are routinely calibrated against known radiometric standards. In the case of WR-214 at Wheeler River, assay results on split core have been received from this zone. However, while assays from several half metre sections of core were locally higher than the probe indicated grades, significant core loss within those sections means any reported assay grade would be unreliable, and the probe indicated grades therefore must be reported herein.

Environmental Services

Revenue from environmental services was $1,136,000 for the three months and $1,812,000 for the six months ended June 30, 2006 compared to $893,000 and $2,345,000 for the comparable periods in 2005. Loss from the division was $11,000 for the three months and $111,000 for the six months ended June 30, 2006 compared to a loss of $11,000 and income of $53,000 for the same periods in 2005.

During the six months ended June 30, 2006, Denison Environmental Services ("DES") provided services under its contract for environmental monitoring and maintenance of the closed mine site of Rio Algom Ltd. at Elliot Lake, under its contract to operate the Kam Kotia water treatment facilities and under its three-year contract for environmental monitoring and maintenance at the INCO Shebandowan mine site.

Corporate and Other

Uranium Participation Corporation

Effective March 30, 2005, Denison entered into an agreement to act as Manager of Uranium Participation Corporation ("Uranium Corp."). Denison receives management fees for the provision of management services and 1.5% commission on the purchase and sale of uranium oxide in concentrates (U308) and uranium hexafluoride (UF6) made on behalf of Uranium Corp. Denison earned $1,248,000 and $1,561,000 in management fees and commissions for the three months and six months ended June 30, 2006 compared with $657,000 earned in the second quarter of 2005.

Corporate Expenses

General corporate expenses were $1,169,000 for the three months and $2,175,000 for the six months ended June 30, 2006 compared to $964,000 and $1,956,000 for the comparable periods in 2005.

Non-cash stock compensation expense relating to stock options granted during the year to employees and directors was $329,000 for the three months and $617,000 for the six months ended June 30, 2006 compared to $447,000 and $681,000 for the comparable periods in 2005.

Other Income (Expense)

Other income (expense) for the six months ended June 30, 2006 includes $1,376,000 of interest earned on invested cash, $461,000 realized recovery on an investment previously written down and a ($326,000) loss on foreign exchange.

Corporate Objectives

Denison's objectives for 2006 are to accomplish the following:

-- Expand uranium resources by investing $5,000,000 in exploration in 2006, and through acquisitions;

-- Sell at least 1,000,000 pounds of U3O8 ;

-- Production of at least 4,000,000 pounds U3O8 at the McClean processing facility of which Denison's share will be 900,000 pounds;

-- At least maintain uranium production earnings at 2005 levels;

-- Complete the mining of the Sue A deposit, make substantial progress toward the mining of the Sue E deposit, and mine a portion of the McClean North deposit through the blind-boring/jet-boring mining techniques;

-- Complete the expansion of the McClean mill to allow for processing of Cigar Lake ore in 2007;

-- Progression of the development of Midwest through the regulatory process towards commencement of stripping the deposit by 2008;

-- Development of the process to recover the nickel and cobalt reserves associated with the uranium at Midwest and at Sue E;

-- Complete further drilling at the Sue E deposit to move the inferred resources into reserves.

Management believes it is on track to meet these objectives except for the annual uranium production levels and uranium production earnings. We now believe that the annual production from McClean in 2006 will be about 3,000,000 pounds U3O8. With lower production levels (and the resulting increased production costs), higher mining costs, primarily attributable to the "blind boring/jet boring program, the production earnings are expected to be lower than 2005 production earnings by up to 20%.

DISCUSSION OF CONSOLIDATED RESULTS

Consolidated revenue for the three months ended June 30, 2006 was $11,349,000 and consolidated net income was $539,000 or $0.02 per share. This compares with revenues of $12,281,000 and consolidated net income of $2,519,000 or $0.10 per share for the three months ended June 30, 2005.

Consolidated revenue for the six months ended June 30, 2006 was $16,857,000 and consolidated net income was $545,000 or $0.02 per share. This compares with revenues of $15,464,000 and consolidated net income of $1,098,000 or $0.04 per share for the six months ended June 30, 2005.

Results by segment are discussed below:

URANIUM PRODUCTION DIVISION RESULTS

Denison's uranium division consists of its 22.5% interest in the producing McClean Lake mine and mill operation and 25.17% interest in the Midwest uranium property in Saskatchewan. Both McClean and Midwest are operated by AREVA Resources Canada Limited (formerly COGEMA Resources Inc.) ("AREVA"). Uranium division results also include reclamation expense of the former Elliot Lake uranium mine.

Results for the three and six months ended June 30, 2006

The uranium production division recorded income of $ 2,245,000 for the three months and $3,617,000 for the six months ended June 30, 2006 compared to income of $3,736,000 for the three months and $3,589,000 for the six months ended June 30, 2005.

The decrease in earnings in the second quarter versus the comparable period last year was the result of lower sales volumes, increased cost of goods sold averaging about $12.00 per pound higher due to increased production costs and Canadian/US dollar exchange rates that were unfavourable compared to last year, offset in part by higher average sales prices. Sales in the quarter were 222,500 pounds U3O8 versus 395,000 pounds in the second quarter last year. US dollar sales prices for the quarter averaged US$36.23 versus US$22.12 in 2005. US/Canadian dollar exchange rates averaged $1.112 in the current quarter compared to $1.228 in the same period last year. The resulting average sales price in Canadian currency was $40.29 for the second quarter in 2006 versus $27.17 for the same period last year.

For the six months ended June 30, 2006, the increase in earnings versus the comparable period last year was the result of lower sales volumes, increased cost of goods sold averaging about $10.00 per pound higher due to increased production costs and Canadian/US dollar exchange rates that were unfavourable compared to last year, offset by higher average sales prices. Sales in the period were 345,000 pounds U3O8 versus 493,000 pounds in the same period last year. US dollar sales prices for the six months averaged US$34.59 versus US$20.63 in 2005. US/Canadian dollar exchange rates averaged $1.1299 in the current period compared to $1.2255 in the same period last year. The resulting average sales price in Canadian currency was $39.08 for the six months in 2006 versus $25.28 for the same period last year. Sales volumes for the first six months represent 35% of our expected sales volumes for the year.

The McClean Lake Joint Venture produced 382,000 and 666,000 pounds of uranium during the three months and six months ended June 30, 2006 compared with 1,562,000 and 2,925,000 pounds during the same periods in 2005. Denison's 22.5% share of production totalled 86,000 pounds during the three months and 150,000 pounds during the six months ended June 30, 2006 compared to 351,000 pounds and 658,000 pounds in the comparable periods in 2005. The primary reasons for lower production in 2006 were lower grade ore feed, variances in the arsenic concentration of the ore feed that resulted in temperature problems in the leach circuit and a shortage of reagents (primarily hydrogen peroxide) due to road closure caused by forest fires. Average mill feed grade for the six month period was 0.68% U3O8 compared to 1.59% U3O8 for the comparable 2005 period.

Unit production costs increased significantly in the quarter compared to the same period last year due to the lower volumes produced, reduced feed grade and variances in the composition of ore being fed to the mill. As production for the year increases, unit production costs will decline and are now expected to average about $12.00 per pound higher than average production costs in 2005. This increase is expected to be reduced by about $2.00 per pound with the addition of a ferric sulphate plant, scheduled to go into service in late 2006 and substantially eliminated when processing of Cigar Lake ores begins in early 2008.

Production for the year is now expected to be about 3,000,000 pounds U3O8 of which Denison's share will be about 675,000 pounds. Actual production levels will depend on the quantity, quality and grade of ore available from mining activities during the year. Mining of the Sue A deposit was completed in the first quarter of 2006 and mining of the Sue E deposit is currently underway and will continue throughout 2006 and 2007. Processing of the ore from Sue A is underway. It is expected that ore from the Sue E deposit will be available in September 2006. The extraction of ore from the McClean North deposit using the "blind-boring/jet boring" technique is expected to commence in the next few weeks. Production will also come from the remainder of the Sue C stockpile and the ability of the operator to recover the high-grade ore contained in the stockpiles will impact actual production levels.

AREVA is planning to undertake an infill drilling program this September to determine if over 7,000,000 pounds of deep mineralization below and south of the planned Sue E pit, currently in inferred resources, can be brought into the reserve category and incorporated into the Sue E mining plan.

Denison pays a Saskatchewan basic uranium royalty of 4% of gross uranium sales after receiving the benefit of a 1% Saskatchewan resource credit. Denison also pays Saskatchewan capital taxes based on the greater of 3.6% of gross uranium sales and capital tax otherwise computed under the Act. For uranium production after July 1, 2006, the factor applied to gross uranium sales for Saskatchewan capital tax purposes will be reduced to 3.3% with further reductions scheduled in 2007 and 2008. The Saskatchewan government also imposes a tiered royalty which ranges from 6% to 15% of gross uranium sales after recovery of mill and mine capital allowances which approximate capital costs. Denison has not paid tiered royalties in the past and has sufficient mill and mine capital and expansion allowances available or anticipated to shelter it from the tiered royalty at current uranium prices for several years.

Expenses related to the former Elliot Lake Uranium Mine

Denison has certain liabilities associated with the decommissioned Elliot Lake uranium mine and the retirees from the Elliot Lake operations.

In the six months ended June 30, 2006, Denison spent $292,000 primarily on monitoring and water treatment activities at its former Elliot Lake sites compared to $274,000 in the comparable period in 2005. In 2006, Denison expects to spend about $630,000 on these activities. All spending is paid for from the Elliot Lake Reclamation Trust, which had a balance of $1,632,000 at June 30, 2006. This balance, with interest earned thereon, is expected to be adequate to fund all monitoring and treatment costs through to December 31, 2011. This spending is expected to decline marginally over the next few years. The balance of the total provision for $4,498,000 represents the estimated present value of ongoing maintenance, monitoring and water treatment.

A group of retirees from Denison's Elliot Lake mine are entitled to certain medical and dental benefits and life insurance. At June 30, 2006 the post employment benefits liability recorded in the consolidated balance sheet was $8,880,000. The actuarial report on this liability as at October 1, 2005 estimated that the actuarial liability is approximately $4,554,000. The transitional surplus is being credited to income at a rate of $393,000 per year. An experience gain of $864,000 established at the time of the October 2005 actuarial valuation is also being credited to income at a rate of $71,000 per year.

2006 Outlook

Uranium sales in 2006 are contracted at about 1,000,000 pounds U3O8. About 33% of these volumes will be sold under legacy contracts at prices well below current market. The balance will be sold at prices in excess of US$30.00 per pound resulting in realized average US dollar prices being significantly higher than in 2005. Denison expects its sales volumes for the year to be apportioned 12%, 23%, 52% and 13% in the first, second, third and fourth quarters.

Production at the McClean Lake mill is now expected by Denison to be about 3,000,000 pounds U3O8 of which Denison's share is about 675,000 pounds. This represents a reduction from the levels of recent years as a result of lower grade ore being processed that contains more arsenic and planned mill shutdowns totalling about four weeks required for scheduled maintenance and to tie in mill expansion facilities being constructed to process ore from the Cigar Lake joint venture, which is scheduled to commence in early 2008. Actual production levels will depend on the quantity and grade of ore available from mining activities during the year.

As a result of lower grade ore and lower production volumes, milling costs per pound are estimated to increase by an average of about $12.00 per pound U3O8 in 2006.

Uranium prices are expected to continue to strengthen and, as a result, uranium revenue in U.S. dollars is expected to be stronger than in 2005. However, U.S. dollar exchange rates will partially offset this gain if the Canadian dollar remains strong. A change of $1.00 per pound in the spot price of uranium is expected to affect 2006 cash flow by $600,000. A change of 3% in the exchange rate of the Canadian dollar versus the U.S. dollar is expected to affect cash flow by about $900,000.

In 2002 definitive agreements were signed enabling the Cigar Lake joint venture to process its ore at the McClean Lake mill. All Cigar Lake ore will be leached at the McClean Lake mill following which the pregnant aqueous solution will be divided between the McClean Lake and Rabbit Lake facilities for processing into uranium concentrates. It is anticipated that toll milling will begin at McClean Lake in early 2008 subject to receipt by the Cigar Lake joint venture of the required regulatory approvals. Construction is continuing on the expansion of the McClean Lake mill to increase the capacity required to receive and process ore from Cigar Lake with the scheduled completion by the end of 2006.

The project description of the Midwest project was submitted to the Canadian Nuclear Safety Commission, the Environmental Assessment Branch of Saskatchewan Environment and the Canadian Environmental Assessment Agency on December 28, 2005. It is proposed that the Midwest deposit be mined as an open pit with further expansion of the JEB mill at McClean where the Midwest ore will be processed. The Midwest Project was previously considered and recommended to proceed, with conditions, in 1997 by the Joint Federal-Provincial Panel on uranium mining developments in Northern Saskatchewan. The Project was approved by the Federal and Provincial Governments in 1998, based on the Panel's recommendation. It is expected that an environmental assessment will be required. Denison anticipates that the environmental assessment and subsequent licensing will be completed in time to commence stripping of the Midwest deposit in 2008.

In 2006, Denison, in conjunction with AREVA and OURD, will continue evaluating two mining technologies: blind shaft mining (also called blind boring) and hydraulic borehole mining (also known as jet boring). Both of these technologies involve drilling an access hole through the sandstone and glacial overburden and extracting the underlying ore material from surface. Briefly, blind shaft mining uses a mechanical device (a reaming head) to cut material and enlarge the mining cavity in the ore horizon, whereas hydraulic borehole mining utilizes a high-pressure water jet. The primary purpose of the evaluation is to improve the economics of these mining technologies as a technique for recovering uranium ore, particularly from smaller deposits. In 2005 testing was conducted which successfully commissioned and to some extent tested in the sandstones, the specialty equipment (namely the mining tools and the mining pipes, engineered and manufactured exclusively for the Pilot Test Program). The achievements of the test mining in 2005 were significant enough to convince Denison to support AREVA's recommendation that the test mining should proceed to drill and test mine from up to 20 holes in 2006 with anticipated production of 500,000 pounds of U3O8. Drilling on an initial five holes has commenced. Three holes have been completed and the extraction of ore is scheduled to commence in the next few weeks.

URANIUM EXPLORATION DIVISION RESULTS

Results for the three months and six months ended June 30, 2006

Denison is engaged in uranium exploration as part of the McClean and Midwest joint ventures as a participant in joint ventures in Saskatchewan at Wheeler River, Wolly, Waterfound, Russell Lake and in Mongolia. Denison's share of exploration spending totalled $1,571,000 for the three months and $3,196,000 for the six months ended June 30, 2006, of which $1,360,000 and $2,803,000 respectively was expensed as it related to exploration on properties without ore reserves. The Denison exploration expenditures year-to-date included $393,000 at the McClean and Midwest properties, $1,594,000 at Wheeler, $535,000 at Wolly, $64,000 at Waterfound, $66,000 at Russell Lake and $386,000 in Mongolia. In the comparable six-month period in 2005, Denison's exploration expenditures totalled $1,240,000 of which $302,000 was spent at McClean and Midwest and $895,000 was spent at Wheeler, Wolly and Waterfound.

Outlook for 2006

Denison's share of exploration spending for 2006 is expected to total $5,500,000 of which $3,100,000 will be spent at the Wheeler River uranium project where Denison is the operator. Denison also expects to spend over $800,000 at the Wolly uranium project. The balance of the exploration spending will be at Midwest, McClean Lake, Waterfound, Russell Lake and in Mongolia. The majority of the exploration spending will be expensed during the year.

DENISON ENVIRONMENTAL SERVICES DIVISION RESULTS

During the six months ended June 30, 2006, Denison Environmental Services ("DES") provided services under its contract for environmental monitoring and maintenance of the closed mine site of Rio Algom Ltd. at Elliot Lake, under its contract to operate the Kam Kotia water treatment facilities and under its three-year contract for environmental monitoring and maintenance at the INCO Shebandowan mine site. Other smaller contracts and consulting projects were also completed.

Results for the three months and six months ended June 30, 2006

Revenue from environmental services was $1,136,000 for the three months and $1,812,000 for the six months ended June 30, 2006 compared to $893,000 and $2,345,000 for the comparable periods in 2005. The division incurred a loss of $11,000 for the three months and $111,000 for the six months ended June 30, 2006 compared to a loss of $11,000 and income of $53,000 for the same periods in 2005.

2006 Outlook

Denison Mines Inc.

Notes to Consolidated Financial Statements

(unaudited)

1. NATURE OF OPERATIONS

Denison Mines is engaged in uranium mining and related activities, including exploration and acquisition of uranium-bearing properties, extraction, processing, selling and reclamation. The environmental services division of the Company provides mine decommissioning and decommissioned site monitoring services for third parties.

Denison Mines's uranium production and exploration activities are carried out principally in Canada through the use of joint ventures. Uranium, the Company's primary product, is produced in the form of uranium oxide in concentrates and sold to various customers around the world for further processing.

Denison Mines is also the manager of Uranium Participation Corporation ("Uranium Corp"), a publicly listed investment holding company which invests substantially all of its assets in uranium. Denison Mines has no ownership interest in Uranium Corp but receives various fees for management services and commissions from the purchase and sale of uranium by Uranium Corp.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Preparation and Estimates

The consolidated financial statements have been prepared by management in accordance with Canadian generally accepted accounting principles ("GAAP"). Interim financial statements do not include all information required by GAAP for annual financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included in these financial statements. The preparation of financial statements in conformity with Canadian generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The most significant estimates are related to the economic lives and recoverability of mining assets, the provisions for site restoration and post-employment benefits and future income taxes, and the evaluation of contingent liabilities. Actual results could differ materially from those estimates. The results of operations for the interim period are not necessarily indicative of the operating results for the full year, primarily due to the timing of deliveries to customers.

These unaudited interim consolidated financial statements and notes should be read in conjunction with the consolidated financial statements of Denison Mines for the year ended December 31, 2005. These statements have not been subject to a review by the Company's auditors.

Consolidation Principles

These consolidated financial statements include the accounts of the Company and its subsidiaries. Denison also has interests in unincorporated ventures and jointly-controlled companies and exercises joint control over these interests through agreements which require that material changes to the policies, objectives and procedures of the joint venture be approved by a percentage of the participating interest sufficiently high enough to prevent any participant from exercising unilateral control over the joint venture. Where Denison has an interest in a jointly-controlled company, or has an interest in an unincorporated venture, the Company recognizes its share of revenues, expenses, assets and liabilities proportionate to its percentage ownership or participating interest.

At June 30, 2006, Denison Mines's significant uranium joint venture ownership interests are as follows:



-----------------------------------------------
Joint Venture Interest Ownership
-----------------------------------------------
McClean Lake Producing 22.50%
Midwest Non-producing 25.17%
Wheeler (1) Non-producing 40.00%
Wolly (2) Non-producing --%
Waterfound Non-producing 15.32%
Mongolia Non-producing 25.00%
-----------------------------------------------
-----------------------------------------------


(1) In October 2004, Denison Mines entered into an option agreement with its joint venture partners to earn a further 20% ownership interest in the project by funding $7,000,000 in exploration expenditures over the next 6 years. As at June 30, 2006, Denison has spent $4,462,000 against this option.

(2) In October 2004, Denison Mines entered into an option agreement with its joint venture partners to earn a 22.5% ownership interest in the project by funding $5,000,000 in exploration expenditures over the next 6 years. The first phase of this agreement requires Denison to fund $1,500,000 of expenditures over fiscal years 2005 and 2006 to earn a 6.5% ownership interest. As at June 30, 2006, Denison has spent $1,057,000 against this option.

AREVA Loan / Credit Facility

On April 17, 2006, Denison Mines terminated its credit facility with AREVA Resources Canada Inc. ("AREVA"). As part of the termination agreement, AREVA and Denison agreed to cancel certain rights which AREVA had in the event of a sale of Denison by way of a merger, take-over bid, amalgamation, plan of arrangement, wind-up, joint venture agreement or other business combination of Denison. The agreement also required Denison to provide its pro-rata share of financial assurances provided under the Mineral Industry Environmental Protection Regulations (1996) in connection with the McClean and Midwest Joint Ventures site restoration obligations. As a result, Denison has provided Letters of Credit from a chartered bank totaling $8,063,775.

-----------------------------------------------------
-----------------------------------------------------


As at June 30, 2006, an additional 1,309,000 shares are available for granting as options under this plan.

Denison Mines has used the Black-Scholes option pricing model to establish the fair value of stock options (and to establish the fair value of warrants associated with unit offerings -- see note 10).

13. SEGMENTED FINANCIAL INFORMATION

Denison Mines operates in four primary operating segments -- uranium production, uranium exploration, environmental services and corporate and other. The uranium segments consist of the exploration for, mining, milling and sale of uranium concentrate. The environmental services segment consists of mine decommissioning services and monitoring of decommissioned sites for third parties. Revenue in the corporate segment represents management fees and commission income earned from Uranium Corp. and expenses include general corporate expenses not allocated to the other segments.

Substantially all of the Company's operations in the uranium production and exploration segments are conducted through the use of unincorporated joint ventures. Uranium joint ventures allocate uranium production and exploration expenses to each joint venture participant and the joint venture participant derives revenue directly from the sale of such product. Mining and milling expenses incurred by the joint venture are included in the cost of inventory.

Major Customers

Denison Mines relies on a small number of customers to purchase a significant portion of its uranium concentrate product. During the six months ended June 30, 2006 and 2005, the aggregate revenue from customers each representing more than 10% of Denison Mines total revenues was $13,484,000 (80%) and $11,269,000 (73%), respectively. In 2006, two customers (2005 -- two customers) each accounted for more than 10% of the Company's gross revenues.

14.RELATED PARTY TRANSACTIONS

On March 30, 2005, Denison Mines entered into a management services agreement with Uranium Corp. Denison Mines and Uranium Corp. are considered to be related parties. The terms of the agreement were subsequently amended pursuant to a special shareholders meeting of Uranium Corp on March 27, 2006. Under the terms of the amended agreement, Denison Mines receives the following fees from Uranium Corp: a) a commission of 1.5% of the gross value of any purchases or sales of uranium completed at the request of the Board of Directors of Uranium Corp; b) a minimum annual management fee of $400,000 (plus reasonable out-of-pocket expenses) plus an additional fee of 0.3% per annum based upon Uranium Corp.'s net asset value between $100,000,000 and $200,000,000 and 0.2% per annum based upon Uranium Corp's net asset value in excess of $200,000,000; c) a fee of $200,000 upon the completion of each equity financing where proceeds payable to Uranium Corp exceed $20,000,000; d) a fee of $200,000 for each transaction or arrangement (other than the purchase or sale of uranium) of business where the gross value of such transaction exceeds $20,000,000 ("an initiative"); and e) an annual fee up to a maximum of $200,000, at the discretion of the Board, for on-going maintenance or work associated with an initiative.

On March 28, 2006, Denison Mines entered into an agreement with Uranium Corp to provide a temporary revolving credit facility not to exceed $25,000,000 to ensure that Uranium Corp had sufficient cash on hand to meet its purchase commitments. The credit facility was terminated on May 24, 2006. Interest under the credit facility was based on Canadian bank prime plus 2%. Standby fees also applied at a rate of 1% of the committed facility amount. During the three month period ending June 30, 2006, Uranium Corp drew $10,000,000 under the facility and subsequently repaid it.

The following transactions were incurred with Uranium Corp during the three month and six month periods ended June 30, 2006 and 2005:

15.CONTINGENT LIABILITIES AND COMMITMENTS

Specific Legal Matters

Elliot Lake Property Tax Complaint

The City of Elliot Lake (the "City") filed complaints with the Ontario Assessment Review Board (the "Board"), alleging that the Municipal Property Assessment Corporation ("MPAC") had: (i) understated the current value which the City is required to use in determining the annual property taxes attributable to the tailings management areas at the Company's decommissioned Elliot Lake mine site and those of other closed uranium mines in Elliot Lake; and (ii) incorrectly categorized these tailings management areas as vacant commercial land, rather than occupied industrial land.

In November 2004, the Board determined that MPAC had used the correct assessed values for the mines sites. However, the Board changed the categorization of the tailings management area to commercial occupied land as opposed to vacant commercial land. The result of the change in categorization will be additional tax that the Company has estimated to be about $5,000 per year.

The City of Elliot Lake has made an Application for Leave to Appeal the above decision to the Divisional Court. The Company believes that the City's Application for Leave is without merit and is unlikely to be successful. The Company intends to oppose the Application. No hearing date has been scheduled. The dollar value of any additional taxes arising from this Appeal, in the event the City were to be successful on its Application and on the Appeal itself, cannot be determined but could be material. No provision has been made for such amounts.

Blue Hill, Maine

The Company is a defendant in an action filed by the State of Maine against Kerramerican, Inc., ("Kerramerican") a subsidiary of Noranda Inc., Black Hawk Mining Ltd. ("Black Hawk") and the Company, regarding potential liability for clean-up costs at a zinc mining site in the state of Maine known as Blue Hill. In addition, Black Hawk and Kerramerican have each asserted cross-claims against Denison for contribution. Denison intends to defend these actions and has counter-claimed against Black Hawk and Kerramerican for indemnity. The activities of Denison Mines Limited ("DML"), a predecessor to Denison, at this site consisted only of limited exploration that did not involve the disposal of any waste and which occurred prior to 1964. Mining activities at the site occurring between 1964 and 1970 were conducted by Black Hawk, a public company in which Denison had a financial interest but did not control. Black Hawk entered into a joint venture with Kerramerican in 1970. Kerramerican was the operator of the joint venture, built processing facilities and operated the mine until it was closed in 1977. Kerramerican was responsible for the decommissioning and reclamation of the site, which was completed in 1983. The site is now the source of some heavy metal contamination of the ground water in the area and further reclamation work is required.

DML has an indemnity from Kerramerican and Black Hawk in an agreement among the parties dated July 1, 1971. The Company has thoroughly examined this issue and believes it has no liability related to the costs of any clean up of the contamination and has made no provision for any costs other than those incurred to date to investigate the matter. Furthermore, the Company believes that, to the extent that liability is determined, Kerramerican and Black Hawk are liable therefore pursuant to the July 1, 1971 indemnity agreement. Notwithstanding the Company's belief that it has no liability, future litigation of the matter cannot be ruled out and as a result, the Company cannot determine the outcome of this matter at this time.

General Legal Matters

The Company is involved, from time to time, in various other legal actions and claims in the ordinary course of business. In the opinion of management, the aggregate amount of any potential liability is not expected to have a material adverse effect on the Company's financial position or results.

Third Party Indemnities

Pursuant to the Denison Arrangement described in note 1 of the 2005 Annual Report of Denison Mines Inc., the Company has agreed to indemnify Denison Energy against any future liabilities it may incur related to the assets or liabilities transferred to Denison Mines on March 8, 2004.

Performance Bonds and Letters of Credit

In conjunction with various contracts and other performance obligations, the Company may be required to issue performance bonds and letters of credit as security to creditors to guarantee the Company's performance. Any potential payments which might become due under these items would be related to the Company's non-performance under the applicable contract. As at June 30, 2006, the Company had outstanding bonds and letters of credit of $8,565,000 of which $484,000 was collateralized by restricted cash (see note 6).
