Denison Reports Third Quarter Earnings Of $1.6 Million
              TORONTO, ONTARIO--Denison Mines Limited reported earnings of              $1,637,000 for the three months ended September 30, 2000.  This              compares with earnings of $7,859,000 in the third quarter of 1999,             which included earnings of $7,600,000 from the sale of the              Company's interest in the White Rose oil field.  Revenue in the              third quarter was $9,452,000, which included $6,200,000 from              uranium sales and $2,714,000 from the Ecuador oil royalty compared             with $2,497,000 in the same period in 1999.  There were no uranium             sales or revenues from the Ecuadorian royalty in the third quarter             of 1999. 
              Earnings for the nine months ending September 30 were $3,237,000              ($0.01 per share) compared with $14,152,000 ($0.04 per share) in              the corresponding period of 1999.  Earnings for the nine months              ending September 30, 1999 included a $6,067,000 reduction in the              Company's provision for decommissioning its Greek operations and              the White Rose gain of $7,735,000.  Earnings before interest,              taxes, depreciation and amortization for the nine months ended              September 30, 2000 were $16,537,000 compared with $14,526,000 for              the nine months ended September 30, 1999.  Cash and marketable              securities exceeded $19 million or almost $0.06 per share at              September 30, 2000. 
              Operations at the McClean Lake uranium facility are steadily              improving.  The production rate in the third quarter was 24% above             the nominal design capacity of six million pounds per year and              unit operating costs continued to decline.  Ore from the first              phase of the Sue C pit has been mined and stockpiled. Stripping is             ongoing in preparation for mining the 18 million pound second              phase of the Sue C ore in the later part of 2001.  Stockpiled Sue              C and JEB ore is sufficient to feed the mill at design capacity              for about two years. 
              Uranium sales volumes in the third quarter and year to date are              19% and 47% respectively of scheduled sales volumes for 2000.  The             McClean loan balance has increased to $72.8 million at September              30 as a result of the cost of increasing uranium inventory levels              for sales in the fourth quarter, stripping costs, and timing of              third quarter sales receipts. 
              Denison Environmental Services has been active with several small              contracts which will be substantially completed before year end.               A new five-year contract to maintain and monitor five mine sites              is currently being finalized. 
              Royalty receipts from Ecuador continue to be received.  Full              payment is expected before the end of the first quarter 2001. 
              Denison has entered into a joint venture agreement with a private              company whereby Denison can earn a 50% working interest in up to              8,500 acres in an oil exploration joint venture in Saskatchewan.              At least seven separate prospects have been identified and Denison             is committed to pay 70% of the cost to drill one well on at least              two of these prospects following completion and interpretation of              a 3D seismic program. The first well has been completed at a cost              to Denison of $300,000 and testing of the two oil-bearing zones is             currently underway.  Drilling of a second exploration well has              commenced. 
              Corporate cost reduction measures have been implemented and are              expected to decrease those costs by about 15% next year. 
              Mr. Craig Bamford has been appointed Vice-President, Finance of              the Corporation, replacing Chris Jamieson.  Craig is a chartered              accountant, joined Denison in 1982 and has most recently been the              Controller of the Company.

Actual results may differ from expected results for a variety of              reasons including the factors discussed in the Company's              Management Discussion and Analysis section of its 1999 Annual              Report.

              /T/
              1. As required by the new rules of the Canadian Institute of              Chartered Accountants ("CICA"), the Company has adopted the              liability method of accounting for income taxes effective January              1, 2000.  The new CICA rules require computation of the Federal              and Saskatchewan income tax provision  using theoretical tax rates             which currently apply without being allowed to record and take              advantage of the offsetting reduction to taxable income as a              result of utilizing  previously unrecognized tax  deductions.  As              a result, year-to-date net earnings have been reduced  by              $2,337,000.  This additional expense, included in income and              resource taxes on the Consolidated Statement of Earnings,  does              not increase liabilities, since the benefit of utilizing these tax             deductions is considered to be an adjustment to asset values              assigned at the time of the restructuring and therefore $2,337,000             has been credited to Retained Earnings. Prior year results have              not been restated.  
              The net impact of the new CICA rules is that Denison has deducted              a tax expense in computing net earnings and earnings per share              under the new method when no actual tax liability exists              corresponding to this increased expense. 
              The Company now has in excess of  $170 million  of non capital              losses and capital cost allowances, together with substantial              earned depletion and net capital losses which can be carried              forward to shelter its future earnings from federal and provincial             income taxes, except in Ontario.  The resulting benefit of these              deductions will be recognized in the future as an increase in              Retained Earnings to offset the tax expenses shown in earnings. 
               2. A Greek court has determined that further payments should be              made to 227 of the former unionized employees of the Company's              Prinos oil operations where production ceased in November 1998.               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 judgement which              could range up to $11 million.  An appeal has been filed and a              hearing is now scheduled for January 30, 2001. The closing of              Greek operations was accepted as valid by the Greek State in an              agreement dated November 16, 1999 which was subsequently ratified              by the Greek Parliament.  The results of an appeal cannot be              determined at this time.  The Company has an accrual of $1.6              million at September 30, 2000 to cover any remaining liabilities              in Greece. 
               3. As of  October 24, 2000 the Company has 317,871,201 Common              Shares issued and  outstanding.  On a fully diluted basis, after              giving effect to the exercise of Common Share Purchase Warrants              and stock options, the Company would have 345,856,201 Common              Shares issued.
