  Denison Announces First Quarter Net Earnings Of $895,000
  TORONTO, ONTARIO--Denison Mines Limited today announced net  earnings of $895,000 ($0.00 per share) on revenue of $4,787,000  for the three months ended March 31, 2001, compared with earnings  of $1,212,000 ($0.00 per share) on revenue of $5,971,000 in the  first quarter of 2000. The financial statements for the first  quarter of 2001 reflect improved results from both uranium  operations and environmental services. The first quarter of 2000  included revenue and earnings from Greece of $1,153,000 realized  on the final lifting of oil produced prior to shutdown in 1998. 
  Although this quarter marks an end to earnings arising from the  Ecuador royalty payments, we are working hard to replace oil and  gas revenue and earnings. We are participating in a horizontal  well with Flatland following the very encouraging vertical well  completed early in the year. We are also finalizing the  acquisition of new prospective acreage in Saskatchewan from  Flatland. Denison has engaged Jennings Capital Inc. to assist us  with the identification of other Canadian oil and gas assets. 
  Our plan to further reduce general corporate expenses is on track  for a 15% reduction in the year. 
  The first quarter report to shareholders follows. 
  Denison is hosting a conference call on Tuesday, May 1, 2001  starting at 9:00 a.m. (Toronto time) to discuss the year-end  results. The conference call will be web cast. www.ir-live.com. A  recording of the call will be available approximately two hours  after the call, through a link on Denison's web site  www.denisonmines.com. 
  OPERATIONAL REVIEW  
  Mining 
  McClean Lake Uranium 
  McClean Lake production in the first quarter of 2001 was 27% above the nominal capacity of 6 million pounds per year. Denison's 22.5% share of production was 430,000 pounds. Planned mill production in 2001 is at least 600,000 pounds per month. Uranium sales in the  first quarter represented approximately 9% of planned annual sales volume. 
  Mining of the Sue C pit continued in the quarter. Mining of this  pit is expected to be complete by the end of 2001, providing  sufficient ore in stockpiles to feed the mill at nominal rates for three to four years depending upon production rate. When mining is completed, cash costs will be reduced, enabling faster debt  reduction. 
  Midwest Uranium Project 
  With an expected increase in uranium reserves at McClean Lake,  uncertainty of the timing and costs of Midwest development and in  order to eliminate the obligation to pay advance and future  royalties on production from Midwest, Denison decreased its  interest in Midwest from 25% to 19.96% effective March 31, 2001.  Cogema Resources Inc. also reduced its interest from 70.5% to  54.84%. 
  Denison Environmental Services 
  Denison Environmental Services was active in the decommissioning  of the Caland site near Atikokan in Ontario this quarter.  Preparations were also made for Denison Environmental Services to  begin operating and monitoring five decommissioned mine sites for  Rio Algom on April 1, 2001. The demand for used mining equipment  continued to be weak during the quarter and, as a result, asset  sales revenues declined. 
  Oil and Gas 
  During the quarter, one successful vertical oil well was drilled  by the Flatland joint venture in which the Company has earned a  50% interest. Additional horizontal drilling is planned for the  second quarter. 
  Denison has engaged a consultant to assist in the identification  of Canadian oil and gas assets appropriate for the Company to  acquire. 
  On March 27, 2001, the Court of Appeal in Greece heard the  Company's appeal of the lower court decision awarding further  severance to former unionized employees. The timing of a decision  is not known. 
  MANAGEMENT'S DISCUSSION AND ANALYSIS 
  Results of Operations 
  Revenue for the first three months of 2001 includes $2,698,000  (2000 - $2,479,000) from uranium sales, $529,000 (2000 - $146,000) from Environmental Services, and $1,521,000 (2000 - $2,193,000)  from the Ecuador royalty. Oil and gas revenue in the first quarter of 2000 included $1,153,000 from final sale of inventory in the  tanks produced before shutdown in 1998.  
  McClean sales revenue in the first quarter of 2001 benefited from  higher U.S. exchange rates. Sales in the first quarter represent  approximately 9% of planned sales in 2001 under long-term  contracts. Readers are cautioned that sales volumes will vary from quarter to quarter depending on which contracts deliveries are  made under and upon the timing of deliveries requested by  customers. Sales volumes in the remainder of the year are  currently forecast to be 23% in the second quarter, 19% in the  third quarter and 49% in the fourth quarter. Sales are made under  long-term contracts and approximately 17% of sales under long-term contracts are sensitive to fluctuations in spot prices. 
  Segmented earnings for mining improved by $627,000 as a result of  lower milling costs at the McClean operation and reduced interest  expenses. Environmental Services benefited from higher levels of  decommissioning work in the quarter, which more than offset lower  asset sales revenues. Oil and gas earnings declined by $2.0  million partly as a result of the elimination of Greece oil  revenue. The Company has now earned its remaining entitlement to  the Ecuador oil royalty. 
  Income tax expense for the quarter declined by $837,000 as a  result of the Company's plan to shelter its 2001 earnings with  previously unrecognized future income tax benefits. 
  Liquidity and Cash Resources 
  During the quarter, operations generated cash flow of $4.5  million. Repayments of $11 million (2000 - $8.2 million) were made on long-term debt from the collection of prior year uranium  receivables. Borrowings financed an increase in uranium  concentrate inventory of $4.8 million, mining costs and working  capital requirements at McClean. 
  Capital expenditures increased from $383,000 to $1,015,000,  principally as a result of the Flatland oil and gas drilling  program. Cash flow in the first quarter of 2000 was adversely  affected by payment of $12.6 million to pay the Oceanic lawsuit  award. 
  Cash and marketable securities declined $2.7 million to $5.7  million at March 31, reflecting a $3.0 million prepayment on the  Cogema debt facility. The Company now has the ability on 45 days'  notice to reborrow for any purpose $15.4 million, up from $12.1  million at December 31, 2000.

  Notes to Consolidated Financial Statements (Unaudited) 
  Denison Mines Limited 
  1. Basis of Presentation 
  The accompanying unaudited interim consolidated financial  statements are prepared in accordance with Canadian generally  accepted accounting principles ("GAAP").  
  While management believes that the disclosures presented are  adequate, these unaudited interim consolidated financial  statements and notes should be read in conjunction with Denison's  consolidated financial statements included in the Annual Report  for the year ended December 31, 2000. 
  The accounting policies and methods of application are consistent  with those used in the 2000 audited financial statements. Certain  prior year balances have been reclassified to conform with the  current year's basis of presentation. 
  2. Long-term Debt 
  As at March 31, the Company had made prepayments of $15,000,000  (December 31, 2000 - $12,000,000) on the McClean Lake loan  facility and had the ability to redraw $15,391,000 (December 31,  2000 - $12,131,000), upon 45 days notice, representing the amount  prepaid and interest savings. 
  3. Contingent Liability 
  In November 1998, production ceased at the Company's former Prinos oil and gas operation, offshore Greece, and employees received  severance pay averaging 16 months' wages. All operating facilities were subsequently transferred to the Greek state pursuant to an  amendment to the concession agreement ratified by the Greek  parliament in 1999, pursuant to which the wells, production  platform and processing facilities associated with the oil and gas operation were transferred to the Greek State in consideration of  the Greek State assuming all of the Consortium's remaining  decommissioning liabilities. A group of former employees sued the  Greek operating company with the objective of seeking both  reinstatement and further termination pay. In early 2000, a Greek  court determined the termination of the employees was invalid and  abusive, and that further payments should be made to 227 of the  former employees. As many of the employees were employed or  received other compensation during 1999 that reduces the amount  awarded to them, it is difficult to assess the magnitude of the  judgment that could result in payments to former employees of up  to $13 million. An appeal of the award was heard on March 27,  2001. Timing of a decision is unknown and the results of the  appeal cannot be determined at this time. The Company has an  accrual of $1.3 million at March 31, 2001 to cover any remaining  liabilities in Greece. 
  4. Capital Stock 
  As of April 30, 2001, the Company has 317,871,195 Common Shares  issued and outstanding and 10,999,992 Common Share Purchase  Warrants outstanding. Between December 31, 2000 and April 30,  2001, 200,000 Common Share Purchase Options were issued and as a  result on April 30, 2001 11,395,000 options were outstanding and  exercisable at prices ranging from $0.12 to $0.39 per Common  Share. If all Common Share Purchase Warrants and stock options had been exercised on April 30, 2001, the Company would have  340,266,187 Common Shares issued.
